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…
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.
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.
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.
