Objective Morality & Arguments For God

with 2 comments

Morality is certainly an important facet of the human condition, and as a philosophical topic of such high regard, it clearly deserves critical reflection and a thorough analysis.  It is often the case that when people think of ethics, moral values, and moral duties, religion enters the discussion, specifically in terms of the widely held (although certainly not ubiquitous) belief that religions provide some form of objective foundation for morals and ethics.  The primary concern here regarding morals is determining whether our morals are ontologically objective in some way or another, and even if they are, is it still accurate to describe morality as some kind of an emergent human construct that is malleable and produced by naturalistic socio-biological processes?

One of the most common theistic arguments, commonly referred to as the Divine Command Theory, states that the existence of a God (or many gods for that matter) necessarily provides an ontologically objective foundation for morals and ethics.  Furthermore, coinciding with this belief are the necessary supportive beliefs that God exists and that this God is inherently “good”, for if either of these assumptions were not also the case, then the theistic foundation for morals (i.e. what is deemed to be “good”) would be unjustified. The assumption that God exists, and that this God is inherently “good” is based upon yet a few more assumptions, although there is plenty of religious and philosophical contention regarding which assumptions are necessary, let alone which are valid.

Let’s examine some of the arguments that have been used to try and prove the existence of God as well as some arguments used to show that an existent God is necessarily good. After these arguments are examined, I will conclude this post with a brief look at moral objectivity including the most common motivations underlying its proposed existence, the implications of believing in theologically grounded objective morals, and finally, some thoughts about our possible moral future.

Cosmological Argument

The Cosmological Argument for God’s existence basically asserts that every effect has a cause, and thus if the universe began to exist, it too must have had a cause.  It is then proposed that the initial cause is something transcendent from physical reality, something supernatural, or what many would refer to as a God.  We can see that this argument most heavily relies on the initial assumption of causality.  While causality certainly appears to be an attribute of our universe, Hume was correct to point out the problem of induction, whereby, causality itself is not known to exist by a priori reasoning, but rather by a posteriori reasoning, otherwise known as induction.  Because of this, our assumption of causality is not logically grounded, and therefore it is not necessarily true.

Clearly science relies on this assumption of causality as well as on the efficacy of induction, but its predictive power and efficacy only requires that causal relationships hold up most of the time, although perhaps it would be better to say that science only requires that causal relationships hold up with the phenomena it wishes to describe.  It is not a requirement for performing science that everything is causally closed or operating under causal principles.  Even quantum mechanics has shown us acausal properties whereby atomic and subatomic particles exhibit seemingly random behavior with no local hidden variables found.  It may be the case that ontologically speaking, the seemingly random quantum behavior is actually governed by causal processes (albeit with non-local hidden variables), but we’ve found no evidence for such causal processes. So it seems unjustified to assume that causality is necessarily the case, not only because this assumption has been derived from logically uncertain induction alone, but also because within science, specifically within quantum physics, we’ve actually observed what appear to be completely acausal processes.  As such, it is certainly both possible and plausible that the universe arose from acausal processes as well, with this possibility heavily supported by the quantum mechanical principles that underlie it.

To provide a more satisfying explanation for how something could come from nothing (as in some acausal process), one could look at abstract concepts within mathematics for an analogy.  For example, if 0 = (-1) + (1), and “0” is analogous to “nothing”, then couldn’t “nothing” (i.e. “0”) be considered equivalent to the collection of complementary “somethings” (e.g. “-1” and “+1”)?  That is, couldn’t a “0” state have existed prior to the Big Bang, and this produced two universes, say, “-1” and “+1”?  Clearly one could ask how or why the “0” state transformed into anything at all, but if the collection or sum of those things are equivalent to the “0” which one started with, then perhaps the question of how or why is an illogical question to begin with.  Perhaps this ill-formulated question would be analogous to asking how zero can spontaneously give rise to zero.  In any case, quantum mechanical principles certainly defy logic and intuition, and so there’s no reason to suppose that the origins of the universe should be any less illogical or counter-intuitive.  Additionally, it is entirely possible that our conceptions of “nothing” and “something” may not be ontologically accurate or coherent with respect to cosmology and quantum physics, even if we think of those concepts as trivial and seemingly obvious in other domains of knowledge.

Even if the universe was internally causal within its boundaries and thus with every process inside that universe, would that imply that the universe as a whole, from an external perspective, would be bound by the same causal processes?  To give an analogy, imagine that the universe is like a fishbowl, and the outer boundary of the fishbowl is completely opaque and impenetrable.  To all inhabitants inside the fishbowl (e.g. some fish swimming in water), there isn’t anything to suppose except for what exists within the boundary, i.e., the water, the fish, and the laws of physics that govern the motion and physical processes therein (e.g. buoyant or freely floating objects and a certain amount of frictional drag between the fish and the water).  Now it could be that this fishbowl of a universe is itself contained within a much larger environment (e.g. a multi-verse or some meta-space) with physical laws that don’t operate like those within the fishbowl.  For example, the meta-space could be completely dry, where the fishbowl of a universe isn’t itself buoyant or floating in any way, and the universe (when considered as one object) doesn’t experience any frictional drag between itself and the meta-space medium around it.  Due to the opaque surface of the fishbowl, the inhabitants are unaware that the fishbowl itself isn’t floating, just as they are unaware of any of the other foreign physical laws or properties that lay outside of it.  In the same sense, we could be erroneously assuming that the universe itself is a part of some causal process, simply because everything within the universe appears to operate under causal processes.  Thus, it may be the case that the universe as a whole, from an external perspective that we have no access to, is not governed by the laws we see within the universe, be they the laws of time, space, causality, etc.

Even if the universe was caused by something, one can always ask, what caused the cause?  The proposition that a God exists provides no solution to this problem, for we’d then want to know who or what created that God, and this would create an infinite regress.  If one tries to solve the infinite regress by contending that a God has always existed, then we can simplify the explanation further by removing any God from it and simply positing that the universe has always existed.  Even if the Big Bang model within cosmology is correct in some sense, what if the universe has constantly undergone some kind of cycle whereby a Big Bang is preceded by and eventually succeeded by a Big Crunch ad infinitum?  Even if we have an epistemological limitation from ever confirming such a model, for example, if the information of any previous universe is somehow lost with the start of every new cycle, it is certainly a possible model, and one that no longer requires an even more complex entity to explain, such as a God.

Fine-Tuning Argument

It is often claimed by theists that the dimensionless physical constants in our universe appear to be finely tuned such that matter, let alone intelligent life, could exist.  Supposedly, if these physical constants were changed by even a small amount, life as we know it (including the evolution of consciousness) wouldn’t be possible, therefore, the universe was finely tuned by an intelligent designer, or a God.  Furthermore, it is often argued that it has been finely tuned for the eventual evolution of conscious human beings.

One question that can be posed in response to this argument is whether or not the physical constants could be better than they currently are, such that the universe would be even more conducive to matter, life, and eventually intelligent life.  Indeed, it has been determined that the physical constants could be much better than they are, and we can also clearly see that the universe is statistically inhospitable to life, empirically supported by the fact that we have yet to find life elsewhere in the universe.  Statistically, it is still very likely that life exists in many other places throughout the universe, but it certainly doesn’t exist in most places.  Changing the physical constants in just the right way would indeed make life ubiquitous.  So it doesn’t appear that the universe was really finely tuned at all, at least not for any of the reasons that have been supposed.

There have also been other naturalistic theories presented as possible solutions to the fine-tuning argument, such as that of the Multi-verse, whereby we are but one universe living among an extremely large number of other universes (potentially infinite, although not necessarily so), and each universe has slightly different physical constants.  In a way, we could say that a form of natural selection among universes occurs, where the appearance of a finely tuned universe is analogous to the apparent design in biological nature.  We now know that natural selection along with some differentiation mechanisms are all that are necessary to produce the appearance of designed phenotypes.  The same thing could apply to universes, and by the anthropic principle, we can see that those universes that had physical constants within a particular range conducive to life, and eventually intelligent life, would indeed be the type of universe that we are living in such that we can even ask the question.  That is, some universes could be naturally selected to undergo the evolution of consciousness and eventually self-awareness.

There have been other theories presented to account for the appearance of a finely tuned universe such as a quantum superposition of initial conditions during the Big Bang, but they utilize the same basic principles of cosmic differentiation and natural selection, and so need not be mentioned further.  In any case, we can see that there are several possible naturalistic explanations for what appear to be finely tuned physical constants.

An even more important point worth mentioning is the possibility that every combination of physical constants could produce some form of consciousness completely unfathomable to us. We have yet to solve the mind-body problem (if it is indeed solvable), and so without knowing what physical mechanism produces consciousness, are we justified in assuming which processes can not produce consciousness? Even if consciousness as we know it is limited to carbon-based biological organisms with brains, can we justifiably dismiss the possibility of completely different mechanisms and processes that lead to some form of self-regulating “life”, “consciousness”, or “awareness”? Even a form of life or consciousness that does not involve brains, let alone atoms or molecules?  If this is the case, then all universes could have some form of “life” or “consciousness”, even if they would never come close to falling within our limited definition of such concepts.

“God is Good” & The Ontological Argument

The assumption that a God which exists must necessarily be a good God is definitely necessary for one to believe that the existence of that God provides an ontologically objective foundation for morals and ethics. So what exactly is the basis for this assumption that a God must necessarily be good?

This assumption has been derived by many from some versions of what is known as the Ontological Argument for God’s existence. This argument, believed to have been first asserted by St. Anselm of Canterbury in the year 1078 CE, basically asserts that God, by definition, is the greatest conceivable being.  However, if the greatest conceivable being is supposedly limited to the mind, that is, as a mental construct, then an even greater conceivable being is possible, namely one that actually exists outside of the mind as an entity in reality, therefore, God exists in both the mind as well as in reality.  Furthermore, regarding the concept of God being good, some people take this argument further and believe that the greatest conceivable being, that is, a God, also has to be good, since it is believed that the most perfect God, by definition, would deserve to be worshipped, and would only create or command that which is best.  So it follows then by the Ontological Argument, that not only God exists, but also that God must necessarily be good.

One obvious criticism to this argument is the fact that just because one can conceive of something, that act in itself certainly doesn’t make that conception exist in any sense other than as a mental construct.  Even if I can conceive of a perfect object, like a perfect planet that is perfectly spherical for example, this doesn’t mean that it necessarily has to exist.  Even if I limit my conceptions to a perfect God, what if I conceive of two perfect beings, with the assumption that two perfect beings are somehow better than one?  Does this mean that two perfect beings must necessarily exist? How about an infinite number of perfect beings? Isn’t an infinite number of infinitely perfect beings the best conception of all?  If so, why isn’t this conception necessarily existent in reality as well?  Such an assertion would indeed provide proof for polytheism.  One could certainly argue over which conceptions are truly perfect or the best, and thus which should truly produce something necessarily in reality, but regardless, one still hasn’t shown how conceptions alone can lead to realities.  Notice also that the crux of St. Anselm’s argument is dependent on one’s definition of what God is, which leads me to what I believe to be a much more important criticism of the Ontological Argument.

The primary criticism I have with such an argument, or any argument claiming particular attributes of a God for that matter, is the lack of justification for assuming that anyone could actually know anything about a God.  Are we to assume that any attributes at all of a God should necessarily be within the limits of human comprehension?  This assumption of such a potent human attribute of understanding sounds incredibly pretentious, egotistical, and entirely unsubstantiated.  As for the common assumptions about what God is, why would a God necessarily have to be different from, or independent of, the universe itself, as presumably required for an ontologically objective foundation for morality?  Pantheists for example (which can be classified as atheists as far as I’m concerned), assume that the universe itself is God, and thus the universe needed no creator nor anything independent of itself.  Everything in the universe is considered a part of that God and that’s simply all there is to it.

If one takes a leap of faith and assumes that a presumed God not only exists, but is indeed also independent of the universe in some way, aren’t they even less justified in making claims about the attributes of this God?  Wouldn’t it be reasonable to assume that they’d have an even larger epistemological barrier between themselves and an external, separate, and independent God?  It seems incredibly clear that any claims about what a God would be like are based on the unsubstantiated assumption that humans must necessarily have access to such knowledge, and in order to hold such a view, it seems that one would have to abandon all logic and reasoning.

Euthyphro dilemma

One common challenge to the Divine Command Theory mentioned earlier is the Euthyphro dilemma, whereby one must determine if actions are good simply because a presumed God commands them, or rather that the presumed God commands particular actions because they are good independently of that God.  If the former premise is chosen, this would imply that whatever a God commands, even if humans or others see those commands to be immoral, that they must be moral and good regardless of human criticisms. If the latter premise is chosen, then morality is clearly not dependent on God thus defeating the Divine Command Theory altogether as well as the precept that God is omnipotent (since God in this case wouldn’t ultimately have control over defining what is good and what is not good).  So for those that ascribe to the Divine Command Theory, it appears that they also have to accept that all moral actions (no matter how immoral they may seem to us) are indeed moral simply because a God commands them. One should also contemplate that if a God were theoretically able to modify its commands over time (presumably possible with an omnipotent God), then any theological objective foundation for morals would be malleable and subject to change, thereby reducing, if not defeating, the pragmatic utility of that objective foundation.

There are many people that have absolutely no problem with such Divine Command Theory assumptions, including the many theists that accept and justify the purported acts of their God (or gods), despite there being an enormous number of people outside of those particular religions that see many of those acts as heinous and morally reprehensible (e.g. divinely authorized war, murder, rape, genocide, slavery, racism, sexism, sexual-orientationism, etc.).  Another problem that exists for the Divine Command Theory is the problem of contradictory divine commands, whereby many different religions each claim to follow divine commands despite the fact that the divine commands of one religion may differ from another.  These differences clearly indicate that even if the Divine Command Theory were true, the fact that people don’t agree on what those divine commands are, and the fact that there is no known method for confirming what the true divine commands are, illustrates that the theory is pragmatically useless as it fails to actually provide any way of knowing what these ontologically objective morals and ethics would be.  In other words, even if morals did have a theologically-based ontologically objective foundation, it appears that we have an epistemological barrier from ever confirming such an objective status.

Argument from Morality for the Existence of God

Some believe in what is often referred to as the “Moral Argument for God” or the “Argument from Morality”, whereby at least one variation asserts that because moral values exist in some sense, it then follows that a God must necessarily exist, since nature on its own appears to be morally neutral, as nature doesn’t appear to have any reason or mechanism for producing moral values from purely physical or materialistic processes. One can also see that by accepting such an assertion, if one wants to believe in the existence of an objective foundation for morals, one need only believe that morals exist, for this supposedly implies that God exists, and it is presumed that an existent God (if one ascribes to the common assumption that “God” must be good as explained earlier) also provides an objective foundation for morals.

Well, what if morals are not actually separate from naturalistic mechanisms and explanations?  While nature may appear to be morally neutral, there is evidence to suggest that what we often call “morality” (at least partially) resulted from natural selection pressures ingraining into humans a tendency for reciprocal altruism among other innate behaviors that have been beneficial to the survival of our highly social species, or at least beneficial in the context of the environment we once lived in prior to our cultural evolution into civilization.  For example, altruism, which can roughly be expressed or represented by the Golden Rule (i.e. do to others what you would have them do to you), is a beneficial behavior for it provides an impulse toward productive cooperation and reciprocal favors between individuals.  Another example of innate morality would be the innate aversion from incest, and this also makes evolutionary sense because incestual reproduction is more likely to produce birth defects due to genetically identical recessive mutations or problematic genes being expressed more often.

These innate tendencies, that is, what we innately feel to be good and bad behaviors are what we often label as “moral” and “immoral” behaviors, respectively.  It is certainly plausible that after our unconscious, pre-conscious, or primitively conscious ancestors evolved into self-aware and more complex conscious beings that were able to culturally transmit information over generations as well as learn new behavior, they also realized that their innate tendencies and feelings were basically fixed attributes of their human nature that couldn’t simply be unlearned or modified culturally.  Without having any idea where these innate tendencies came from, due to a lack of knowledge about evolutionary biology and psychology, humans likely intuitively concluded that moral values (or at least those that are innate) were something supernaturally based or divinely ordained.  It is at least arguable that not all morals that humans ascribe to are necessarily innate, as there also appears to be a malleable moral influence derived from the cultural transmission of certain memes, often aided by our intellectual ability to override certain instincts.  However, I think it would be more accurate to say that our most fundamental goals in life in terms of achieving personal satisfaction (through cultivating virtues and behaving with respect to the known consequences of our actions) constitutes our fundamental morality — and I think that this morality is indeed innate based on evolutionary psychology, biology, etc.

Additionally, a large number of these culturally transmitted behaviors (that we often label as “morals”) often align with our innate moral tendencies anyway, for example, memes promoting racism may be supported by our natural tendency to conveniently lump people into groups and see outsiders as dangerous or threatening.  Or the opposite may occur, for example, when memes promoting racial equality may be supported by our natural tendency for racially-neutral reciprocal altruism.  Clearly what we tend to call “morals” are an amalgam of culturally transmitted ideas as well as innate predispositions, that is, they result from socio-biological or cultural-biological processes — even if there is an innate fundamental morality that serves as an objective foundation for those culturally constructed morals.

Moreover, since other animals (or at least most other animals) do not seem to exhibit what we call moral behavior, it is likely that most humans saw it (and many still continue to see it) as a unique property of humans alone, and thus somehow existing independently of the rest of the nature around them.  One response to this anthropocentric perspective would be to note that if we look at other animals’ behavior, they may just as easily be described as having their own morals based on their own naturally selected innate behavioral tendencies, even if those morals are completely different from our own, and even if those morals are not as intelligently informed due to our more complex brains and self-awareness (most notably in the case of culturally transmitted morals).  Now it may be true that what evolutionary biologists, psychologists, and sociologists have discovered to be the mechanism or explanation for human morality, as well as how we choose to define that morality naturalistically, is not something that certain people want to accept.  However, that lack of acceptance or lack of comfort doesn’t make it any less true or any less plausible.  It seems that some people simply want morality to have a different kind of ontological status or some level of objectivity, such that they can find more solace in their convictions and also to support their anthropocentric presuppositions.

Objective Morality, Moral Growth, and our Moral Future

While the many arguments for God have been refuted or at least highly challenged, it appears that the actual existence of God isn’t nearly as important as people’s belief in such a God, especially when it comes to concepts such as morality.  Sartre once quoted Dostoyevsky as saying, “If there is no God, then everything is permissible.”  I personally feel that this quote illustrates quite eloquently why so many people feel compelled to argue that a God exists (among other reasons), as many seem to feel that without the notion of a God existing, the supposed lack of an objective foundation for morality will lead people to do whatever they want to do, and thus people will no longer ascribe to truly “moral” behavior.  However, as we can clearly see, there are many atheists who behave quite morally relative to the Golden Rule, if we must indeed specify some moral frame of reference.  There are also plenty of people who believe in a God and yet behave in ways that are morally reprehensible relative to the same Golden Rule standard.  The key difference between the atheist and the theist, at least concerning moral objectivity, is that the atheist, by definition, doesn’t believe that any of their behavior has a theologically grounded objective ontological status to justify it, although the atheist may still believe in some type of moral objectivity (likely grounded in a science of morality, which is a view I actually agree with).  On the other hand, the theist does believe in a theological basis for moral objectivity, so if either the atheist or theist behave in ways that you or I would find morally reprehensible, the theist alone would actually feel religiously obligated to do so.

Regarding the concern for a foundation for morals, I think it is fair to say that the innate morality of human beings, that is, those morals that have been ingrained in us for evolutionary reasons (such as altruism), could be described as having a reliable foundation, even if not an ontologically objective one.  On top of this “naturally selected” foundation for morality, we can build upon it by first asking ourselves why we believe moral behavior is important in the first place.  If humans overwhelmingly agree that morality is important for promoting and maximizing the well-being of conscious creatures (with higher-level conscious creatures prioritized over those with less complex brains and lower-level consciousness), or if they agree with the contra-positive of that proposition, that morality is important for inhibiting and minimizing the suffering of conscious creatures, then one could say that humans at least have a moral axiom that they could ascribe to.  This moral axiom, i.e., that moral behavior is defined as that which maximizes the well-being of conscious creatures (as proposed by many “Science of Morality” proponents such as Sam Harris), is indeed an axiom that one can further build upon, refine, and implement through the use of epistemologically objective methods in science.  Even if this “moral axiom” doesn’t provide an ontologically objective morality, it has a foundation that is grounded on human intuition, reason, and empirical data.  If one argues that this still isn’t as good as having a theologically grounded ontologically objective morality, then one must realize that the theological assumptions for said moral objectivity have no empirical basis at all.  After all, even if a God does in fact exist, why exactly would a God necessarily provide an objective foundation for morals?  More importantly, as I mentioned earlier, there appears to be no epistemologically objective way to ascertain any ontologically objective morals, so it doesn’t really matter anyway.

One can also see that the theist’s position, in terms of which morals to follow, is supposedly fixed, although history has shown us that religions and their morals can change over time, either by modifying the scripture or basic tenets, or by modifying the interpretation of said scripture or basic tenets. Even if moral modifications take place with a religion or its followers, the claim of moral objectivity (and an intentional resistance to change those morals) is often maintained, paradoxically. On the other hand, the atheist’s position on morals is not inherently fixed and thus the atheist is at least possibly amenable to reason in order to modify the morals they ascribe to, with the potential to culturally adapt to a society that increasingly abhors war, murder, rape, genocide, slavery, racism, sexism, sexual-orientationism, etc.  Whereas the typical theist can not morally adapt to the culturally evolving world around them (at least not consciously or admittedly), even as more evidence and data are obtained pertaining to a better understanding of that world, the typical atheist indeed has these opportunities for moral growth.

As I’ve mentioned in previous posts, human nature is malleable and will continue to change as our species continues to evolve.  As such, our innate predispositions regarding moral behavior will likely continue to change as it has throughout our evolutionary history.  If we utilize “engineered selection” through the aid of genetic engineering, our moral malleability will be catalyzed and these changes to human nature will precipitate incredibly quickly and with conscious foresight.  Theists are no exception to evolution, and thus they will continue to evolve as well, and as a result their innate morality will also be subject to change.  Any changes that do occur to human nature will also likely affect which memes are culturally transmitted (including memes pertaining to morality) and thus morality will likely continue to be a dynamic amalgam of both biological and cultural influences.  So despite the theistic fight for an objective foundation for morality, it appears that the complex interplay between evolution and culture that led to theism in the first place will continue to change, and the false idea of any ontologically objective foundation for morality existing will likely continue to dissipate.

History has shown us that reason as well as our innate drive for reciprocal altruism is all we need in order to behave in ways that adhere to the Golden Rule (or to some other moral axiom that maximizes the well-being of conscious creatures).  Reason and altruism have also given us the capability of adapting our morals as we learn more about our species and the consequences of our actions. These assets, combined with a genetically malleable human nature will likely lead us to new moral heights over time. In the mean time, we have reason and an innate drive for altruism to morally guide us. It should be recognized that some religions which profess the existence of a God and an objective morality also abide by some altruistic principles, but many of them do not (or do so inconsistently), and when they do, they are likely driven by our innate altruism anyway. However, it takes belief in a God and its objective foundation for morality to most effectively justify behaving in any way imaginable, often in ways that negate both reason and our instinctual drive for altruism, and often reinforced by the temptation of eternal reward and the threat of eternal damnation. In any case, the belief in moral objectivity (or more specifically moral absolutes), let alone the belief in theologically grounded moral objectivity or absolutism, appears to be a potentially dangerous one.

Religious Paradigms in the Wake of Science

with 2 comments

Albert Einstein once said “Science without religion is lame, religion without science is blind.” From my perspective, I see the latter as most certainly true as science is the only way we’ve been able to gain a falsifiable world view of our universe. As for the former, it seems that Einstein was mainly pointing out how religion has largely precipitated from the human aspiration to ascertain truth, and without that drive for truth, science would be ineffective. That also sounds reasonable, as early on and throughout most of human history, religion was more or less the dominant world view used to provide many explanations for the unknown. Many if not most of these explanations were supernatural and the world view in general was also highly anthropomorphic and anthropocentric, perhaps due to its highly subjective basis and the failure to see that subjectivity bias as a fundamental problem (even if it sometimes produces more intuitive explanations). For a more in depth analysis of religion, I recommend you read one of my previous posts.

As people stumbled upon science, realizing that the same empirical and causally-based methodologies used to tackle everyday problems could actually be applied to the investigation of all phenomena, it has been slowly but surely replacing the religious world views with a more objective perspective as the human quests for truth, understanding, and predictive power are perpetuated. In the hopes of maintaining many of the old religious world views, there has no doubt been an enormous amount of religious opposition to science. It’s certainly not difficult to see why so many different religious proponents oppose science. After all, the pragmatic knowledge and explanatory power derived from science has replaced the hundreds of different gods and supernatural explanations proposed over the centuries, and it has also been taking power away from the priests and clergy whose authority throughout history has been based on the presumed existence of those gods and supernatural processes. Above and beyond the fact that science has been eliminating the “gods of the gaps” one by one, science has also been refuting some primary and often necessary assumptions within certain religions. Overall, it seems that the religious world views are slowly fading away in the wake of science. Let’s examine a few…

Human Origins

There is a strong belief held by many religious proponents that human beings along with all other species were created by a deity in their present form. Science has shown us no evidence of any deities, but it has shown us a plethora of evidence within evolutionary biology (among other disciplines) which shows that human beings, like all other life forms on Earth, have indeed evolved from a common ancestor thus forming the diversity of life we see today. Furthermore, we are seeing many different species continue to evolve (including human beings). Despite the scientific consensus that evolution is a fact, there are a large number of people that ignore the evidence in order to preserve their creation origin myths as well as to preserve many other parts of their old world view. While this ignorance may be seen as inconsequential to some (people are entitled to their own beliefs after all), it definitely becomes problematic when it enters and poisons the educational and political spheres of society where reason and intellect are needed most.

Some people have actually gone so far as to try and add Creationism as a complement to the Theory of Evolution currently being taught within the science curriculum of various public schools, despite the fact that the creationist’s claims aren’t supported by any scientific evidence, and thus should remain in the academic realms of cultural studies, religious studies, and mythology. To make matters worse, many religious proponents have also tried to use pseudo-scientific arguments to disprove evolution (although to no avail). Some have even resorted to using the intellectually dishonest (or merely ignorant) argument claiming that “evolution is just a theory”, not realizing that the meaning of the word “theory” within science is quite different from the common everyday usage. Whereas the common everyday usage of the word “theory” is meant to imply a “hypothesis”, the scientific usage implies an explanation with a factual basis that is generally supported by most if not all of the scientific community within the relevant fields. Einstein’s General Theory of Relativity is no different and thus would also be considered as “just a theory”, but we know for a fact that some force which we call “gravity” does indeed exist, and this force also produces measurable temporal dilation, as well as the non-Euclidean or curved space effects predicted by the theory. While some of the details of these theories may remain under contention, and while the theories may be incomplete in one way or another, the main crux of these scientific theories are widely accepted as scientific facts.

These kinds of arguments and tactics have far less precedent, for in the past, religious claims were largely supported by religious authority and intuition alone and didn’t require falsifiable scientific support. As science has continued to gain more influence and followers through its explanatory power, and as more educated people begin to participate in these kinds of public discourses, the necessity of scientifically grounded arguments has grown substantially. So it isn’t all that surprising to see many of the people with religious-based world views try and find scientific arguments to support their case, although it is obviously hypocritical and inconsistent when the same people undermine science when it no longer supports their position. The crucial difference worth noting here is that science is ultimately about trying to find an explanatory and descriptive model that fits the data best, whereas those trying to prove religious beliefs to be true are effectively cherry-picking data to fit a presupposed model. That is, science is always willing to scrap a poor model for a better one that has more explanatory and predictive power as more and more data is collected, whereas religion clings to one model and one model only no matter how poorly it fits the ever increasing amount of data and despite it’s usual lack of explanatory and predictive power.

Teleological Evolution of Humans

Evolutionary theists believe that evolution is factual, but some of them also believe that evolution has had a specific purpose or end-goal in mind determined by a deity, namely to produce human beings (another example of religious anthropocentrism).  In a few of these religious accounts, it has been suggested that once humans evolved from other life forms, they were given a soul and have been participating in some kind of an ongoing religious narrative.  Some have claimed that humans evolved to worship some god(s), to prepare for an apocalypse, to prepare for the afterlife, and other similar stories.  The main point here is that within these types of religious claims, the human species is purportedly the final speciation goal of evolution, and as a result, humans are thought to be the most remarkable, most intellectually capable, and most important species that will ever exist.

In terms of the scientific credibility of such claims, none of the claims are falsifiable except perhaps one — that humans are the end-all be-all for evolution and speciation, or to put it another way, that humans (or another species for that matter) will not evolve further (let alone evolve to produce a species that is more remarkable or one with more intelligent capabilities than homo sapiens).  We can already see that the assumption that humans will no longer evolve is patently false by noticing some relatively recent evolutionary changes to human beings, including the otherwise unnecessary ability for some human adults to digest lactose (this mutation became favorable after the recent development of agriculture and dairy farming several thousand years ago), the existence of specific disease resistances (and their genetic markers) within certain ethnic populations, and other gene pool changes due to genetic drift.

Perhaps more importantly, with the recent development of genetic engineering, we are beginning to consciously and directly guide our own evolution at the molecular level (and the evolution of other species).  As this technology develops further, we are likely to change extremely quickly into a completely different species, and one with more advanced capabilities engineered into the genome. Interestingly enough, there hasn’t been any evidence for the teleological evolution of any species until relatively recently, but it is human beings that are teleologically driving it through both artificial and, what I call, “engineered” selection.

Free Will

If science has shown us anything, it has shown us that there is a causal structure that exists in the world around us in which events that occur are ultimately caused by prior events. If this weren’t the case, then we could never successfully apply the scientific method, let alone live our daily lives with any predictable order or structure. Fortunately, because of the causal (and potentially deterministic) nature of our universe, we’ve been able to successfully formulate hypotheses, test them, and use the results to make further testable predictions.  Regarding free will, there is no known way for humans (or any other entity or object for that matter) to circumvent this causality without their actions being causa sui which would not only undermine the process of rational thought (which depends on causal thought processes), but would also go against every bit of scientific evidence we have obtained thus far.

Even if the randomness proposed within quantum mechanics were ontologically the case (which we’ll likely never know), we all know that randomness can’t produce freely willed actions either, since there have to be non-random conscious intentions and thought processes behind any deliberate action.  So whether the universe is ontologically deterministic or indeterministic (i.e. random), classical free will is logically incompatible with either possibility. Obviously this presents a serious problem to those religious views which assume that humans do in fact possess free will. Concepts such as moral responsibility, human fate in some proposed afterlife, karma, etc., lose their luster when free will is taken out of the equation since this would imply that any spiritual fate supposed isn’t something we can actually change or control anyway, and thus any implemented punishment or reward is ultimately futile.

Despite the fact that we don’t have free will, we all live with the illusion of free will since we don’t directly experience the prior causes to our thoughts and subsequent actions, and thus we truly feel that we self-cause those thoughts and actions.  In the grand scheme of things, even without any free will, we can see that our societal approach of implementing laws, crime deterrence measures, and any punishment-reward system for that matter, isn’t based on the assumption that we can freely choose our behaviors so much as they are based on their efficacy to maximize safety, productivity, as well as what society deems to be acceptable behavior.  It’s efficacy is accomplished primarily through the physical constraint measures put into place as well as the pragmatic application of psychological conditioning principles.

It doesn’t ultimately matter whether or not we could have chosen to behave differently unless one is trying to maintain certain metaphysical presuppositions, such as those proposed in many religions. However, our recognition that free will doesn’t exist can certainly affect how we approach problems in society. As a result of science demonstrating that we lack free will through the discovery of causal constraints such as genes, the body’s internal environment, and the body’s external physical environment (including that which causes the psychological conditioning of the brain), we’re definitely becoming more able to address the actual root causes of many problematic behaviors. In doing so, rather than wasting resources and erroneously blaming an individual for not “choosing” to behave differently (as in many religions), we can appropriately view every individual as an innocent amalgam of genetic and environmental information (regardless of their behavior) and then take more effective measures to improve their behavior by attempting to change any problematic genes and environmental factors.

Struggle for Morality

One of the most pressing issues regarding the human condition is the constant struggle to behave in ways that society deems to be moral. Many religions have their own ideas about what is considered to be moral behavior and they often claim that their particular morals are ordained by a god or some form of divine authority. It is also common that morality and immorality play an important role within various religious narratives.  For example, within the Abrahamic religions, if a person commits what the religion deems to be immoral acts, that is, if they “sin”, and this person does not repent or have their sins absolved, they are destined to eternal damnation.  Within Christianity, “sin” is considered an inevitable act passed down from generation to generation ever since the supposed “fall of man” which, as the story goes, began with a first descendent, named Adam.  This concept of seeing humans as inherent sinners is sometimes referred to as “original sin”.

As was mentioned in the previous section, humans’ lack of free will suggests that humans ultimately have no control over whether they “sin” or not.  Behavior is determined by prior causes such as a person’s genes and the psychological conditioning they’ve undergone throughout their lives.  Evolutionary biologists have also shown that the reasons for humans behaving in ways that society or various religions deem immoral is because of selfish genes as well as an ongoing conflict between biological instincts and societal conventions and expectations.

The strategy that genes tend to implement through their respective phenotypes (including behavior) tend to perpetuate those genes through means of self-preservation, reproductive success, and subsequent child-rearing success.  Additionally, because of the incredible speed of cultural evolution and ever-changing social conventions, humans may find difficulties adhering to particular conventions due to their biological evolution lagging behind that cultural evolution. To give some examples, if people kill others or steal, it is likely (or was likely long ago) to increase one’s chances of survival or increase one’s chances of successful mating by gaining power, property, and social status.  Infidelity could also be seen as a result of being sexually attracted to others because they may provide better genes for new offspring or simply provide more offspring.  Also, if humans are naturally more of a polygamous primate, it would make sense that monogamy, even if the current societal convention, would be difficult to maintain. Thus, there are many possible reasons for why humans behave the way they do, and science has been continuing to enlighten us with these reasons as we gain more information from evolutionary biology and psychology (among other disciplines).

As for the religious claim that humans will always be immoral, a few things must be made clear. For one, morality is largely determined by society, and so what is considered moral in one society may be considered immoral in another. Despite the claim by some religious proponents that religions provide some kind of objective foundation for ethics and morals, we can see that different religions often proclaim different morals, thus it is clear that no such objectivity exists. Science and reason on the other hand do provide a nice resource for answering moral questions by showing us in detail the consequences of our actions (such that we can better determine how we ought to behave), by providing us with a clearer picture of how the world really is so that our moral goals aren’t based on false pretenses, and by providing us with increasingly better ways to achieve those moral goals.

As we continue to evolve as humans or into another species entirely, our innate feelings or instincts about what is moral or immoral will likely continue to change (as will our behavior) since anything that is innate has a biological basis. Most importantly, as we continue to consciously guide our own species’ evolution through genetic engineering, we will have the power to shape human nature into anything we desire. In other words, we aren’t necessarily trapped in a struggle for morality as many religions claim, for we are going to have greater and greater abilities to change our instinctual behavior such that we are naturally inclined to behave in any way that society desires. The key point here is that, as opposed to some religious views which assume that mankind is forever doomed to immoral behavior, science is providing a way out of this supposed predicament.

Final Thoughts

It’s not at all surprising to see certain religious groups highly opposed to science, for there are countless ways that science has been threatening to their world view. Even the fear of death which has likely attracted people to religions for the promise of eternal life is being addressed by science as advances in genetic engineering, medicine, and artificial intelligence work toward increasing life expectancy potentially to the theoretical upper limit (i.e. for as long as the universe is able to support life, given the Second Law of Thermodynamics, etc.).

One striking parallel between many religious claims and the actual efficacy of science is that science truly appears to be providing the ultimate salvation of our species (and whatever species we will become). However, it is being accomplished by taking the ever increasing knowledge acquired over time and addressing every problem we face within the human condition, one by one. While religion has played an important role in history, most notably, in the human quest for truth — it seems clear to me that history has indeed also shown us that the more we accept and use science to learn about the universe, the better chance we have to achieve our goals as our species continually evolves.

An Evolved Consciousness Creating Conscious Evolution

Two Evolutionary Leaps That Changed It All

As I’ve mentioned in a previous post, human biological evolution has led to the emergence of not only consciousness but also a co-existing yet semi-independent cultural evolution (through the unique evolution of the human brain).  This evolutionary leap has allowed us to produce increasingly powerful technologies which in turn have provided a means for circumventing many natural selection pressures that our physical bodies would otherwise be unable to handle.

One of these technologies has been the selective breeding of plants and animals, with this process often referred to as “artificial” selection, as opposed to “natural” selection since human beings have served as an artificial selection pressure (rather than the natural selection pressures of the environment in general).  In the case of our discovery of artificial selection, by choosing which plants and animals to cultivate and raise, we basically just catalyzed the selection process by providing a selection pressure based on the plant or animal traits that we’ve desired most.  By doing so, rather than the selection process taking thousands or even millions of years to produce what we have today (in terms of domesticated plants and animals), it only took a minute fraction of that time since it was mediated through a consciously guided or teleological process, unlike natural selection which operates on randomly differentiating traits leading to differential reproductive success (and thus new genomes and species) over time.

This second evolutionary leap (artificial selection that is) has ultimately paved the way for civilization, as it has increased the landscape of our diet and thus our available options for food, and the resultant agriculture has allowed us to increase our population density such that human collaboration, complex distribution of labor, and ultimately the means for creating new and increasingly complex technologies, have been made possible.  It is largely because of this new evolutionary leap that we’ve been able to reach the current pinnacle of human evolution, the newest and perhaps our last evolutionary leap, or what I’ve previously referred to as “engineered selection”.

With artificial selection, we’ve been able to create new species of plants and animals with very unique and unprecedented traits, however we’ve been limited by the rate of mutations or other genomic differentiating mechanisms that must arise in order to create any new and desirable traits. With engineered selection, we can simply select or engineer the genomic sequences required to produce the desired traits, effectively allowing us to circumvent any genomic differentiation rate limitations and also allowing us instant access to every genomic possibility.

Genetic Engineering Progress & Applications

After a few decades of genetic engineering research, we’ve gained a number of capabilities including but not limited to: producing recombinant DNA, producing transgenic organisms, utilizing in vivo trans-species protein production, and even creating the world’s first synthetic life form (by adding a completely synthetic or human-constructed bacterial genome to a cell containing no DNA).  The plethora of potential applications for genetic engineering (as well as those applications currently in use) has continued to grow as scientists and other creative thinkers are further discovering the power and scope of areas such as mimetics, micro-organism domestication, nano-biomaterials, and many other inter-related niches.

Domestication of Genetically Engineered Micro and Macro-organisms

People have been genetically modifying plants and animals for the same reasons they’ve been artificially selecting them — in order to produce species with more desirable traits. Plants and animals have been genetically engineered to withstand harsher climates, resist harmful herbicides or pesticides (or produce their own pesticides), produce more food or calories per acre (or more nutritious food when all else is equal), etc.  Plants and animals have also been genetically modified for the purposes of “pharming”, where substances that aren’t normally produced by the plant or animal (e.g. pharmacological substances, vaccines, etc.) are expressed, extracted, and then purified.

One of the most compelling applications of genetic engineering within agriculture involves solving the “omnivore’s dilemma”, that is, the prospect of growing unconscious livestock by genetically inhibiting the development of certain parts of the brain so that the animal doesn’t experience any pain or suffering.  There have also been advancements made with in vitro meat, that is, producing cultured meat cells so that no actual animal is needed at all other than some starting cells taken painlessly from live animals (which are then placed into a culture media to grow into larger quantities of meat), however it should be noted that this latter technique doesn’t actually require any genetic modification, although genetic modification may have merit in improving these techniques.  The most important point here is that these methods should decrease the financial and environmental costs of eating meat, and will likely help to solve the ethical issues regarding the inhumane treatment of animals within agriculture.

We’ve now entered a new niche regarding the domestication of species.  As of a few decades ago, we began domesticating micro-organisms. Micro-organisms have been modified and utilized to produce insulin for diabetics as well as other forms of medicine such as vaccines, human growth hormone, etc.  There have also been certain forms of bacteria genetically modified in order to turn cellulose and other plant material directly into hydrocarbon fuels.  This year (2014), E. coli bacteria have been genetically modified in order to turn glucose into pinene (a high energy hydrocarbon used as a rocket fuel).  In 2013, researchers at the University of California, Davis, genetically engineered cyanobacteria (a.k.a. blue-green algae) by adding particular DNA sequences to its genome which coded for specific enzymes such that it can use sunlight and the process of photosynthesis to turn CO2 into 2,3 butanediol (a chemical that can be used as a fuel, or to make paint, solvents, and plastics), thus producing another means of turning our over abundant carbon emissions back into fuel.

On a related note, there are also efforts underway to improve the efficiency of certain hydro-carbon eating bacteria such as A. borkumensis in order to clean up oil spills even more effectively.  Imagine one day having the ability to use genetically engineered bacteria to directly convert carbon emissions back into mass-produced fuel, and if the fuel spills during transport, also having the counterpart capability of cleaning it up most efficiently with another form of genetically engineered bacteria.  These capabilities are being further developed and are only the tip of the iceberg.

In theory, we should also be able to genetically engineer bacteria to decompose many other materials or waste products that ordinarily decompose extremely slowly. If any of these waste products are hazardous, bacteria could be genetically engineered to breakdown or transform the waste products into a safe and stable compound.  With these types of solutions we can make many new materials and have a method in line for their proper disposal (if needed).  Additionally, by utilizing some techniques mentioned in the next section, we can also start making more novel materials that decompose using non-genetically-engineered mechanisms.

It is likely that genetically modified bacteria will continue to provide us with many new types of mass-produced chemicals and products. For those processes that do not work effectively (if at all) in bacterial (i.e. prokaryotic) cells, then eukaryotic cells such as yeast, insect cells, and mammalian cells can often be used as a viable option. All of these genetically engineered domesticated micro-organisms will likely be an invaluable complement to the increasing number of genetically modified plants and animals that are already being produced.

Mimetics

In the case of mimetics, scientists are discovering new ways of creating novel materials using a bottom-up approach at the nano-scale by utilizing some of the self-assembly techniques that natural selection has near-perfected over millions of years.  For example, mollusks form sea shells with incredibly strong structural/mechanical properties by their DNA coding for the synthesis of specific proteins, and those proteins bonding the raw materials of calcium and carbonate into alternating layers until a fully formed shell is produced.  The pearls produced by clams are produced with similar techniques. We could potentially use the same DNA sequence in combination with a scaffold of our choosing such that a similar product is formed with unique geometries, or through genetic engineering techniques, we could modify the DNA sequence so that it performs the same self-assembly with completely different materials (e.g. silicon, platinum, titanium, polymers, etc.).

By combining the capabilities of scaffolding as well as the production of unique genomic sequences, one can further increase the number of possible nanomaterials or nanostructures, although I’m confident that most if not all scaffolding needs could eventually be accomplished by the DNA sequence alone (much like the production of bone, exoskeleton, and other types of structural tissues in animals).  The same principles can be applied by looking at how silk is produced by spiders, how the cochlear hair cells are produced in mammals, etc.  Many of these materials are stronger, lighter, and more defect-free than some of the best human products ever engineered.  By mimicking and modifying these DNA-induced self-assembly techniques, we can produce entirely new materials with unprecedented properties.

If we realize that even the largest plants and animals use these same nano-scale assembly processes to build themselves, it isn’t hard to imagine using these genetic engineering techniques to effectively grow complete macro-scale consumer products.  This may sound incredibly unrealistic with our current capabilities, but imagine one day being able to grow finished products such as clothing, hardware, tools, or even a house.  There are already people working on these capabilities to some degree (for example using 3D printed scaffolding or other scaffolding means and having plant or animal tissue grow around it to form an environmentally integrated bio-structure).  If this is indeed realizable, then perhaps we could find a genetic sequence to produce almost anything we want, even a functional computer or other device.  If nature can use DNA and natural selection to produce macro-scale organisms with brains capable of pattern recognition, consciousness, and computation (and eventually the learned capability of genetic engineering in the case of the human brain), then it seems entirely reasonable that we could eventually engineer DNA sequences to produce things with at least that much complexity, if not far higher complexity, and using a much larger selection of materials.

Other advantages from using such an approach include the enormous energy savings gained by adopting the naturally selected economically efficient process of self-assembly (including less changes in the forms of energy used, and thus less loss) and a reduction in specific product manufacturing infrastructure. That is, whereas we’ve typically made industrial scale machines individually tailored to produce specific components which are later assembled into a final product, by using DNA (and the proteins it codes for) to do the work for us, we will no longer require nearly as much manufacturing capital, for the genetic engineering capital needed to produce any genetic sequence is far more versatile.

Transcending the Human Species

Perhaps the most important application of genetic engineering will be the modification of our own species.  Many of the world’s problems are caused by sudden environmental changes (many of them anthropogenic), and if we can change ourselves and/or other species biologically in order to adapt to these unexpected and sudden environmental changes (or to help prevent them altogether), then the severity of those problems can be reduced or eliminated.  In a sense, we would be selecting our own as well as other species by providing the proper genes to begin with, rather than relying on extremely slow genomic differentiation mechanisms and the greater rates of suffering and loss of life that natural selection normally follows.

Genetic Enhancement of Existing Features

With power over the genome, we may one day be able to genetically increase our life expectancy, for example, by modifying the DNA polymerase-g enzyme in our mitochondria such that they make less errors (i.e. mutations) during DNA replication, by genetically altering telomeres in our nuclear DNA such that they can maintain their length and handle more mitotic divisions, or by finding ways to preserve nuclear DNA, etc. If we also determine which genes lead to certain diseases (as well as any genes that help to prevent them), genetic engineering may be the key to extending the length of our lives perhaps indefinitely.  It may also be the key to improving the quality of that extended life by replacing the techniques we currently use for health and wellness management (including pharmaceuticals) with perhaps the most efficacious form of preventative medicine imaginable.

If we can optimize our brain’s ability to perform neuronal regeneration, reconnection, rewiring, and/or re-weighting based on the genetic instructions that at least partially mediate these processes, this optimization should drastically improve our ability to learn by improving the synaptic encoding and consolidation processes involved in memory and by improving the combinatorial operations leading to higher conceptual complexity.  Thinking along these lines, by increasing the number of pattern recognition modules that develop in the neo-cortex, or by optimizing their configuration (perhaps by increasing the number of hierarchies), our general intelligence would increase as well and would be an excellent complement to an optimized memory.  It seems reasonable to assume that these types of cognitive changes will likely have dramatic effects on how we think and thus will likely affect our philosophical beliefs as well.  Religious beliefs are also likely to change as the psychological comforts provided by certain beliefs may no longer be as effective (if those comforts continue to exist at all), especially as our species continues to phase out non-naturalistic explanations and beliefs as a result of seeing the world from a more objective perspective.

If we are able to manipulate our genetic code in order to improve the mechanisms that underlie learning, then we should also be able to alter our innate abilities through genetic engineering. For example, what if infants could walk immediately after birth (much like a newborn calf)? What if infants had adequate motor skills to produce (at least some) spoken language much more quickly? Infants normally have language acquisition mechanisms which allow them to eventually learn language comprehension and productivity but this typically takes a lot of practice and requires their motor skills to catch up before they can utter a single word that they do in fact understand. Circumventing the learning requirement and the motor skill developmental lag (at least to some degree) would be a phenomenal evolutionary advancement, and this type of innate enhancement could apply to a large number of different physical skills and abilities.

Since DNA ultimately controls the types of sensory receptors we have, we should eventually be able to optimize these as well.  For example, photoreceptors could be modified such that we would be able to see new frequencies of electro-magnetic radiation (perhaps a more optimized range of frequencies if not a larger range altogether).  Mechano-receptors of all types could be modified, for example, to hear a different if not larger range of sound frequencies or to increase tactile sensitivity (i.e. touch).  Olfactory or gustatory receptors could also be modified in order to allow us to smell and taste previously undetectable chemicals.  Basically, all of our sensations could be genetically modified and, when combined with the aforementioned genetic modifications to the brain itself, this would allow us to have greater and more optimized dimensions of perception in our subjective experiences.

Genetic Enhancement of Novel Features

So far I’ve been discussing how we may be able to use genetic engineering to enhance features we already possess, but there’s no reason we can’t consider using the same techniques to add entirely new features to the human repertoire. For example, we could combine certain genes from other animals such that we can re-grow damaged limbs or organs, have gills to breathe underwater, have wings in order to fly, etc.  For that matter, we may even be able to combine certain genes from plants such that we can produce (at least some of) our own chemical energy from the sun, that is, create at least partially photosynthetic human beings.  It is certainly science fiction at the moment, but I wouldn’t discount the possibility of accomplishing this one day after considering all of the other hybrid and transgenic species we’ve created already, and after considering the possible precedent mentioned in the endosymbiotic theory (where an ancient organism may have “absorbed” another to produce energy for it, e.g. mitochondria and chloroplasts in eukaryotic cells).

Above and beyond these possibilities, we could also potentially create advanced cybernetic organisms.  What if we were able to integrate silicon-based electronic devices (or something more biologically compatible if needed) into our bodies such that the body grows or repairs some of these technologies using biological processes?  Perhaps if the body is given the proper diet (i.e. whatever materials are needed in the new technological “organ”) and has the proper genetic code such that the body can properly assimilate those materials to create entirely new “organs” with advanced technological features (e.g. wireless communication or wireless access to an internet database activated by particular thoughts or another physiological command cue), we may eventually be able to get rid of external interface hardware and peripherals altogether.  It is likely that electronic devices will first become integrated into our bodies through surgical implantation in order to work with our body’s current hardware (including the brain), but having the body actually grow and/or repair these devices using DNA instruction would be the next logical step of innovation if it is eventually feasible.

Malleable Human Nature

When people discuss complex issues such as social engineering, sustainability, crime-reduction, etc., it is often mentioned that there is a fundamental barrier between our current societal state and where we want or need to be, and this barrier is none other than human nature itself.  Many people in power have tried to change human behavior with brute force while operating under the false assumption that human beings are analogous to some kind of blank slate that can simply learn or be conditioned to behave in any way without limits. This denial of human nature (whether implicit or explicit) has led to a lot of needless suffering and has also led to the de-synchronization of biological and cultural evolution.

Humans often think that they can adapt to any cultural change, but we often lose sight of the detrimental power that technology and other cultural inventions and changes can have over our physiological and psychological well-being. In a nutshell, the speed of cultural evolution can often make us feel like a fish out of water, perhaps better suited to live in an environment closer to our early human ancestors.  Whatever the case, we must embrace human nature and realize that our efforts to improve society (or ourselves) will only have long term efficacy if we work with human nature rather than against it.  So what can we do if our biological evolution is out-of-sync with our cultural evolution?  And what can we do if we have no choice but to accept human nature, that is, our (often selfish) biologically-driven motivations, tendencies, etc.?  Once again, genetic engineering may provide a solution to many of these previously insoluble problems.  To put it simply, if we can change our genome as desired, then we may be able to not only synchronize our biological and cultural evolution, but also change human nature itself in the process.  This change could not only make us feel better adjusted to the modern cultural environment we’re living in, but it could also incline us to instinctually behave in ways that are more beneficial to each other and to the world as a whole.

It’s often said that we have selfish genes in some sense, that is, many if not all of our selfish behaviors (as well as instinctual behaviors in general) are a reflection of the strategy that genes implement in their vehicles (i.e. our bodies) in order for the genes to maintain themselves and reproduce.  That genes possess this kind of strategy does not require us to assume that they are conscious in any way or have actual goals per se, but rather that natural selection simply selects genes that code for mechanisms which best maintain and spread those very genes.  Natural selection tends toward effective self-replicators, and that’s why “selfish” genes (in large part) cause many of our behaviors.  Improving reproductive fitness and successful reproduction has been the primary result of this strategy and many of the behaviors and motivations that were most advantageous to accomplish this are no longer compatible with modern culture including the long-term goals and greater good that humans often strive for.

Humans no longer exclusively live under the law of the jungle or “survival of the fittest” because our humanistic drives and their cultural reinforcements have expanded our horizons beyond simple self-preservation or a Machiavellian mentality.  Many humans have tried to propagate principles such as honesty, democracy, egalitarianism, immaterialism, sustainability, and altruism around the world, and they are often high-jacked by our often short-sighted sexual and survival-based instinctual motivations to gain sexual mates, power, property, a higher social status, etc.  Changing particular genes should also allow us to change these (now) disadvantageous aspects of human nature and as a result this would completely change how we look at every problem we face. No longer would we have to say “that solution won’t work because it goes against human nature”, or “the unfortunate events in human history tend to recur in one way or another because humans will always…”, but rather we could ask ourselves how we want or need to be and actually make it so by changing our human nature. Indeed, if genetic engineering is used to accomplish this, history would no longer have to repeat itself in the ways that we abhor. It goes without saying that a lot of our behavior can be changed for the better by an appropriate form of environmental conditioning, but for those behaviors that can’t be changed through conditioning, genetic engineering may be the key to success.

To Be or Not To Be?

It seems that we have been given a unique opportunity to use our ever increasing plethora of experiential data and knowledge and combine it with genetic engineering techniques to engineer a social organism that is by far the best adapted to its environment.  Additionally, we may one day find ourselves living in a true global utopia, if the barriers of human nature and the de-synchronization of biological and cultural evolution are overcome, and genetic engineering may be the only way of achieving such a goal.  One extremely important issue that I haven’t mentioned until now is the ethical concerns regarding the continued use and development of genetic engineering technology.  There are obviously concerns over whether or not we should even be experimenting with this technology.  There are many reasonable arguments both for and against using this technology, but I think that as a species, we have been driven to manipulate our environment in any way that we are capable of and this curiosity is a part of human nature itself.  Without genetic engineering, we can’t change any of the negative aspects of human nature but can only let natural selection run its course to modify our species slowly over time (for better or for worse).

If we do accept this technology, there are other concerns such as the fact that there are corporations and interested parties that want to use genetic engineering primarily if not exclusively for profit gain (often at the expense of actual universal benefits for our species) and which implement questionable practices like patenting plant and animal food sources in a potentially monopolized future agricultural market.  Perhaps an even graver concern is the potential to patent genes that become a part of the human genome, and the (at least short term) inequality that would ensue from the wealthier members of society being the primary recipients of genetic human enhancement. Some people may also use genetic engineering to create new bio-warfare weaponry and find other violent or malicious applications.  Some of these practices could threaten certain democratic or other moral principles and we need to be extremely cautious with how we as a society choose to implement and regulate this technology.  There are also numerous issues regarding how these technologies will affect the environment and various ecosystems, whether caused by people with admirable intentions or not.  So it is definitely prudent that we proceed with caution and get the public heavily involved with this cultural change so that our society can move forward as responsibly as possible.

As for the feasibility of the theoretical applications mentioned earlier, it will likely be computer simulation and computing power that catalyze the knowledge base and capability needed to realize many of these goals (by decoding the incredibly complex interactions between genes and the environment) and thus will likely be the primary limiting factor. If genetic engineering also involves expanding the DNA components we have to work with, for example, by expanding our base-four system (i.e. four nucleotides to choose from) to a higher based system through the use of other naturally occurring nucleotides or even the use of UBPs (i.e. “Unnatural Base Pairs”), while still maintaining low rates of base-pair mismatching and while maintaining adequate genetic information processing rates, we may be able to utilize previously inaccessible capabilities by increasing the genetic information density of DNA.  If we can overcome some of the chemical natural selection barriers that were present during abiogenesis and the evolution of DNA (and RNA), and/or if we can change the very structure of DNA itself (as well as the proteins and enzymes that are required for its implementation), we may be able to produce an entirely new type of genetic information storage and processing system, potentially circumventing many of the limitations of DNA in general, and thus creating a vast array of new species (genetically coded by a different nucleic acid or other substance).  This type of “nucleic acid engineering”, if viable, may complement the genetic engineering we’re currently performing on DNA and help us to further accomplish some of the aforementioned goals and applications.

Lastly, while some of the theoretical applications of genetic engineering that I’ve presented in this post may not sound plausible at all to some, I think it’s extremely important and entirely reasonable (based on historical precedent) to avoid underestimating the capabilities of our species.  We may one day be able to transform ourselves into whatever species we desire, effectively taking us from trans-humanism to some perpetual form of conscious evolution and speciation.  What I find most beautiful here is that the evolution of consciousness has actually led to a form of conscious evolution. Hopefully our species will guide this evolution in ways that are most advantageous to our species, and to the entire diversity of life on this planet.

Neuroscience Arms Race & Our Changing World View

leave a comment »

At least since the time of Hippocrates, people began to realize that the brain was the physical correlate of consciousness and thought.  Since then, the fields of psychology, neuroscience, and several inter-related fields have emerged.  There have been numerous advancements made within the field of neuroscience during the last decade or so, and in that same time frame there has also been an increased interest in the social, religious, philosophical, and moral implications that have precipitated from such a far-reaching field.  Certainly the medical knowledge we’ve obtained from the neurosciences has been the primary benefit of such research efforts, as we’ve learned quite a bit more about how the brain works, how it is structured, and the ongoing neuropathology that has led to improvements in diagnosing and treating various mental illnesses.  However, it is the other side of neuroscience that I’d like to focus on in this post — the paradigm shift relating to how we are starting to see the world around us (including ourselves), and how this is affecting our goals as well as how to achieve them.

Paradigm Shift of Our World View

Aside from the medical knowledge we are obtaining from the neurosciences, we are also gaining new perspectives on what exactly the “mind” is.  We’ve come a long way in demonstrating that “mental” or “mind” states are correlated with physical brain states, and there is an ever growing plethora of evidence which suggests that these mind states are in fact caused by these brain states.  It should come as no surprise then that all of our thoughts and behaviors are also caused by these physical brain states.  It is because of this scientific realization that society is currently undergoing an important paradigm shift in terms of our world view.

If all of our thoughts and behaviors are mediated by our physical brain states, then many everyday concepts such as thinking, learning, personality, and decision making can take on entirely new meanings.  To illustrate this point, I’d like to briefly mention the well known “nature vs. nurture” debate.  The current consensus among scientists is that people (i.e. their thoughts and behavior) are ultimately products of both their genes and their environment.

Genes & Environment

From a neuroscientific perspective, the genetic component is accounted for by noting that genes have been shown to play a very large role in directing the initial brain wiring schema of an individual during embryological development and through gestation.  During this time, the brain is developing very basic instinctual behavioral “programs” which are physically constituted by vastly complex neural networks, and the body’s developing sensory organs and systems are also connected to particular groups of these neural networks.  These complex neural networks, which have presumably been naturally selected for in order to benefit the survival of the individual, continue being constructed after gestation and throughout the entire ontogenic evolution of the individual (albeit to lesser degrees over time).

As for the environmental component, this can be further split into two parts: the internal and the external environment.  The internal environment within the brain itself, including various chemical concentration gradients partly mediated by random Brownian motion, provides some gene expression constraints as well as some additional guidance to work with the genetic instructions to help guide neuronal growth, migration, and connectivity.  The external environment, consisting of various sensory stimuli, seems to modify this neural construction by providing a form of inputs which may cause the constituent neurons within these neural networks to change their signal strength, change their action potential threshold, and/or modify their connections with particular neurons (among other possible changes).

Causal Constraints

This combination of genetic instructions and environmental interaction and input produces a conscious, thinking, and behaving being through a large number of ongoing and highly complex hardware changes.  It isn’t difficult to imagine why these insights from neuroscience might modify our conventional views of concepts such as thinking, learning, personality, and decision making.  Prior to these developments over the last few decades, the brain was largely seen as a sort of “black box”, with its internal milieu and functional properties remaining mysterious and inaccessible.  From that time and prior to it, for millennia, many people have assumed that our thoughts and behaviors were self-caused or causa sui.  That is, people believed that they themselves (i.e. some causally free “consciousness”, or “soul”, etc.) caused their own thoughts and behavior as opposed to those thoughts and behaviors being ultimately caused by physical processes (e.g. neuronal activity, chemical reactions, etc.).

Neuroscience (as well as biochemistry and its underlying physics) has shed a lot of light on this long-held assumption and, as it stands, the evidence has shown this prior assumption to be false.  The brain is ultimately controlled by the laws of physics since every chemical reaction and neural event that physically produces our thoughts, choices, and behaviors, have never been shown to be causally free from these physically guiding constraints.  I will mention that quantum uncertainty or quantum “randomness” (if ontologically random) does provide some possible freedom from physical determinism.  However, these findings from quantum physics do not provide any support for self-caused thoughts or behaviors.  Rather, it merely shows that those physically constrained thoughts and behaviors may never be completely predictable by physical laws no matter how much data is obtained.  In other words, our thoughts and behaviors are produced by highly predictable (although not necessarily completely predictable) physical laws and constraints as well as some possible random causal factors.

As a result of these physical causal constraints, the conventional perspective of an individual having classical free will has been shattered.  Our traditional views of human attributes including morality, choices, ideology, and even individualism are continuing to change markedly.  Not surprisingly, there are many people uncomfortable with these scientific discoveries including members of various religious and ideological groups that are largely based upon and thus depend on the very presupposition of precepts such as classical free will and moral responsibility.  The evidence that is compiling from the neurosciences is in fact showing that while people are causally responsible for their thoughts, choices, and behavior (i.e. an individual’s thoughts and subsequent behavior are constituents of a causal chain of events), they are not morally responsible in the sense that they can choose to think or behave any differently than they do, for their thoughts and behavior are ultimately governed by physically constrained neural processes.

New World View

Now I’d like to return to what I mentioned earlier and consider how these insights from neuroscience may be drastically modifying how we look at concepts such as thinking, learning, personality, and decision making.  If our brain is operating via these neural network dynamics, then conscious thought appears to be produced by a particular subset of these neural network configurations and processes.  So as we continue to learn how to more directly control or alter these neural network arrangements and processes (above and beyond simply applying electrical potentials to certain neural regions in order to bring memories or other forms of imagery into consciousness, as we’ve done in the past), we should be able to control thought generation from a more “bottom-up” approach.  Neuroscience is definitely heading in this direction, although there is a lot of work to be done before we have any considerable knowledge of and control over such processes.

Likewise, learning seems to consist of a certain type of neural network modification (involving memory), leading to changes in causal pattern recognition (among other things) which results in our ability to more easily achieve our goals over time.  We’ve typically thought of learning as the successful input, retention, and recall of new information, and we have been achieving this “learning” process through the input of environmental stimuli via our sensory organs and systems.  In the future, it may be possible to once again, as with the aforementioned bottom-up thought generation, physically modify our neural networks to directly implant memories and causal pattern recognition information in order to “learn” without any actual sensory input, and/or we may be able to eventually “upload” information in a way that bypasses the typical sensory pathways thus potentially allowing us to catalyze the learning process in unprecedented ways.

If we are one day able to more directly control the neural configurations and processes that lead to specific thoughts as well as learned information, then there is no reason that we won’t be able to modify our personalities, our decision-making abilities and “algorithms”, etc.  In a nutshell, we may be able to modify any aspect of “who” we are in extraordinary ways (whether this is a “good” or “bad” thing is another issue entirely).  As we come to learn more about the genetic components of these neural processes, we may also be able to use various genetic engineering techniques to assist with the necessary neural modifications required to achieve these goals.  The bottom line here is that people are products of their genes and environment, and by manipulating both of those causal constraints in more direct ways (e.g. through the use of neuroscientific techniques), we may be able to achieve previously unattainable abilities and perhaps in a relatively miniscule amount of time.  It goes without saying that these methods will also significantly affect our evolutionary course as a species, allowing us to enter new landscapes through our substantially enhanced ability to adapt.  This may be realized through these methods by finding ways to improve our intelligence, memory, or other cognitive faculties, effectively giving us the ability to engineer or re-engineer our brains as desired.

Neuroscience Arms Race

We can see that increasing our knowledge and capabilities within the neurosciences has the potential for drastic societal changes, some of which are already starting to be realized.  The impact that these fields will have on how we approach the problem of criminal, violent, or otherwise undesirable behavior can not be overstated.  Trying to correct these issues by focusing our efforts on the neural or cognitive substrate that underlie them, as opposed to using less direct and more external means (e.g. social engineering methods) that we’ve been using thus far, may lead to much less expensive solutions as well as solutions that may be realized much, much more quickly.

As with any scientific discovery or subsequent technology produced from it, neuroscience has the power to bestow on us both benefits as well as disadvantages.  I’m reminded of the ground-breaking efforts made within nuclear physics several decades ago, whereby physicists not only gained precious information about subatomic particles (and their binding energies) but also how to release these enormous amounts of energy from nuclear fusion and fission reactions.  It wasn’t long after these breakthrough discoveries were made before they were used by others to create the first atomic bombs.  Likewise, while our increasing knowledge within neuroscience has the power to help society improve by optimizing our brain function and behavior, it can also be used by various entities to manipulate the populace for unethical reasons.

For example, despite the large number of free market proponents who claim that the economy need not be regulated by anything other than rational consumers and their choices of goods and services, corporations have clearly increased their use of marketing strategies that take advantage of many humans’ irrational tendencies (whether it is “buy one get one free” offers, “sales” on items that have artificially raised prices, etc.).  Politicians and other leaders have been using similar tactics by taking advantage of voters’ emotional vulnerabilities on certain controversial issues that serve as nothing more than an ideological distraction in order to reduce or eliminate any awareness or rational analysis of the more pressing issues.

There are already research and development efforts being made by these various entities in order to take advantage of these findings within neuroscience such that they can have greater influence over people’s decisions (whether it relates to consumers’ purchases, votes, etc.).  To give an example of some of these R&D efforts, it is believed that MRI (Magnetic Resonance Imaging) or fMRI (functional Magnetic Resonance Imaging) brain scans may eventually be able to show useful details about a person’s personality or their innate or conditioned tendencies (including compulsive or addictive tendencies, preferences for certain foods or behaviors, etc.).  This kind of capability (if realized) would allow marketers to maximize how many dollars they can squeeze out of each consumer by optimizing their choices of goods and services and how they are advertised. We have already seen how purchases made on the internet, if tracked, begin to personalize the advertisements that we see during our online experience (e.g. if you buy fishing gear online, you may subsequently notice more advertisements and pop-ups for fishing related goods and services).  If possible, the information found using these types of “brain probing” methods could be applied to other areas, including that of political decision making.

While these methods derived from the neurosciences may be beneficial in some cases, for instance, by allowing the consumer more automated access to products that they may need or want (which will likely be a selling point used by these corporations for obtaining consumer approval of such methods), it will also exacerbate unsustainable consumption and other personal or societally destructive tendencies and it is likely to continue to reduce (or eliminate) whatever rational decision making capabilities we still have left.

Final Thoughts

As we can see, neuroscience has the potential to (and is already starting to) completely change the way we look at the world.  Further advancements in these fields will likely redefine many of our goals as well as how to achieve them.  It may also allow us to solve many problems that we face as a species, far beyond simply curing mental illnesses or ailments.  The main question that comes to mind is:  Who will win the neuroscience arms race?  Will it be those humanitarians, scientists, and medical professionals that are striving to accumulate knowledge in order to help solve the problems of individuals and societies as well as to increase their quality of life?  Or will it be the entities that are trying to accumulate similar knowledge in order to take advantage of human weaknesses for the purposes of gaining wealth and power, thus exacerbating the problems we currently face?

Technology, Evolution, and the Fate of Mankind

Introduction

One could easily argue that human technology is merely a by-product of evolution, or to be more specific, a by-product of natural selection, since any animal possessing a brain and body capable of manipulating their environment to such a high degree is likely to have a higher survival rate than those that do not.  Technology can also be seen as an external evolving feature of the human race, that is, it is changing over time based on environmental pressures that exist, yet it is evolving somewhat independently of our own physical evolution.  Environmental pressures aside, it is clear that our technology has also evolved as a result of our own desire for convenience, entertainment, and pure novelty.  Throughout this post, I plan to discuss our intimate relationship with technology, its evolutionary effects, and also how this may affect the future of our species.

Necessity for Survival?

While technology has provided us with many conveniences, it has also become something that many have come to rely on for their survival (albeit to varying degrees).  Certainly one of our largest problems as a species is our unprecedented reliance on so much technology, not to mention the lack of sustainability for its use.  We have so much infrastructure utilizing enormous amounts of non-renewable fossil fuels, and a host of other interconnected electro-mechanical technologies required for the operation of our civilized world.  We also have medicine and other medical devices that so many depend on, whether to survive an accident, to combat a chronic illness, or to compensate for any number of genetic shortcomings.  Whether it’s a need for prescription glasses, anti-biotics, or a dialysis machine, it is clear that there are a large number of people that couldn’t live without many of these technologies (or would be much less likely to survive without it).

Genetic Change Induced by Technology and Society

I find it interesting to think about how the gene pool has changed as a result of our technology.  There are a considerable number of people living with various life-threatening illnesses, poor eye-sight, obesity, diabetes, sexual dysfunction, etc., due in part to the fact that various synthesized pharmaceuticals and medical advancements have allowed many of these people to live long enough and reproduce.  Not long ago, many people living with these types of impairments would have died young and their genes would have been eradicated.  Now it goes without saying that any advancements we’ve made in terms of genetic engineering or gene therapy, that is, any advancements that actually increase our fitness genetically (and can thus be passed on to future offspring), are not an issue.  Rather, it is all of the other advancements that have merely provided a band-aid approach in order for the genetically less-endowed individuals to survive and reproduce.

Now granted, many of the health problems we encounter in society are largely a result of environmental circumstances (caused by technology or otherwise) transpiring ontogenically as opposed to those which are largely inherited genetically.  There are also a large number of conditions surfacing simply because we’ve increased our life expectancy in such a short amount of time.  Regardless, the gene pool has indeed been affected by a plethora of heritable factors resulting from our technologically pampered society.

It must be said that our gene pool has seen this genetically sub-par influx partly due to the fact that the previous environmental pressures that would have eradicated these genes has been replaced with a technologically savvy super-organism that values human life regardless of how much each life contributes to, or detracts from, the longevity of our species.  Unlike most species, we are at least self-aware, and many of us fully understand the possibility that some of our choices may lead to the extinction of our species (as well as others).  However, I believe that this possibility of extinction hasn’t been taken very seriously and thus there hasn’t been enough invested in evaluating the direction we are heading as a species, let alone the direction we are heading as an entire planet.

Engineered Selection

Now it may be that one day our technology will allow us to understand and manipulate our genome (or that of any other species) such that we can prevent and/or cure any disease or handle any environmental change, effectively eliminating our form of natural selection from the evolutionary equation.  After all, if we could simply modify our gene pool in order to survive any environmental change that is otherwise out of our control, then the gradual course for natural selection and the mutations previously required to make it an effective mechanism, would be replaced by what I would call an “engineered selection”.

We’ve already greatly altered natural selection (relative to other animals) by manipulating our own environmental pressures via technology.  We’ve also created artificial selection (i.e. selective breeding) and utilized this to domesticate various plants and animals, as well as to create breeds possessing traits we find advantageous.  If we actually managed to complement this with a mastery in genetic engineering technology, we would potentially be able to “select” our own species (and the future species we’d become) indefinitely.  The key would be in understanding genetic causal relationships, even if this knowledge required the use of complex genetic evolutionary simulations, supercomputers, etc.

I definitely think that the most significant change for our species lies in this field of genetic engineering, as opposed to any other technological niche.  The possibilities provided by mastering genetic engineering are endless.  We may use it in order to design future offspring with genetic traits that we’re already familiar with (preferably to increase their fitness in the present environment as opposed to superficial motivations), we may add traits from other species (e.g. ability to re-grow limbs, develop wings so we can fly, etc.), or we may even employ some method of integrating communication devices or other deemed “synthetic” technologies into our bodies such that they are biologically grown and repairable, etc.  Humans may use this to genetically engineer brains such that the resulting consciousness has completely different properties, or they may be able to use genetic engineering to create consciousness in a biological “robot”.  If genetically engineered brains result in a more beneficial form of consciousness, higher intelligence, etc., then genetic engineering may end up as a sort of cognitive-evolutionary/technological catalyst thus allowing us to exponentially increase our capacities to solve problems and build ever more advanced technologies.  That is, our enhanced brains and the resulting technology produced would help us to further enhance our brains and technology ad infinitum.  The possibilities are endless if we manage to acquire enough knowledge, acquire the ability to produce engineered DNA sequences, and potentially acquire a way to accelerate the ontogenic evolution of anything produced in order to verify experimental hypotheses/theories in the absence of sufficient computer simulation capabilities.

Fate of Mankind

We are definitely on the cusp of a potentially dramatic evolutionary change for our species.  However, we are also at a very vulnerable stage, for much of our technology has caused our gene pool to regress in terms of physical fitness within a society that could one day be deprived of much of this technology.  Technology has also led to an incredible population explosion, mainly due to agriculture and the fossil-fuel-catalyzed industrial revolution.  This population explosion has helped us in some ways by providing an increase in idea collaboration (thus leading to an exponential increase in technological evolution), but it has also led to much more disastrous effects on the environment including an increased difficulty in sustainability.

Now from an evolutionary perspective, one could argue that currently, our technology is but an extension of ourselves, and our well-developed brains have more than compensated for our physical regression.  While this claim has some truth to it (at the moment anyway), if we lost our ability to mass-produce the technology required for industrialized agriculture, running water, medicine, transportation, sanitation, etc., whether caused by depleting our non-renewable energy sources or even caused by something like a solar-induced electro-magnetic pulse that takes out our power distribution systems (i.e. the entire electrical grid), how many would perish as a result?  In my opinion, the ideal level of evolutionary progression should be such that removing any non-renewable energy source or other vulnerable technology isn’t catastrophic to the survival of our species.  This way our species is less vulnerable to anything that forces us to take a step backwards.  Currently, if we did lose our non-renewable infrastructure, I believe it would be catastrophic and it would be the hunter-gatherers and/or smaller-scale agrarians (i.e. those that are completely off the grid) that would survive, rise up and once again dominate the gene pool as was the case with our ancestors.

Will we survive until an exclusively “engineered selection” is attained?  Or will we simply fall off the evolutionary cusp and potentially extinguish ourselves with the very technology that led to civilization in the first place?  The answer may depend on our level of respect and caution for the technology we so often take for granted.
