“The Bounds of Subjectivity”

The world as it really is
Unknowable, despite conviction
We hope for objectivity
And yet we see prediction

Perception is the mind’s best guess, to make some sense of all the mess
Expectations frame the lens, ontology, each one depends

Controlled hallucination
To see what we want to see
Perception is not a mirror
But the bounds of subjectivity

Our minds are but a model, sensations flowing, open throttle
A story written, a narrative, to which high credence we will give

Grounded on abstraction
Toward emotion reason shouts
Embodied filters blinding us
Wishful thinking wins the bout

Behold the power of intuition, as certainty comes to fruition
Housed in our unconscious mind, yet fallible we ought to find

Beliefs entangled with desire
Can I hold this view of mine?
Search for reasons to confirm
True or not, we all assign

Not all views have equal merit, unable to know, unless we share it
Reducing that complexity, except when over-vexed we’ll be

Worlds are shaped by what we want
In how we act and how we view
Rigid ways take hold of us
The old interprets all the new

Emotions are the reason’s master, ignoring this will bring disaster
Hume was right about the passions, finding reasons is our fashion

When evidence begins to mount
Against a highly prized belief
Minds can change, a last resort
From dissonance, we seek relief

Ignore the proof, for it can’t be! Or change your views for harmony
Highlight all coincidence, though it lacks significance

Must I believe what’s likely true?
Not if I can find a way!
A means to cover my own eyes
Truth be damned, emotions stray

Coincidence we seem to find, memories, tricks of the mind
‘Tis the frequency illusion, we’re falling prey to this delusion

The path of least resistance
Always tempting to the end
Sacrificing truth for self
How far the mind can bend

A marvel of our evolution, the ego fights its dissolution
Fallacies run far and wide, despite the logic by our side

Remember what you must
Your world is up to you
Conveniently forget the rest
And false becomes the true

Few will try to face the truth
Combat the bias, critique the “I”
Only the bravest make attempts
By far the most would rather die

By far the most would rather lie
To themselves, to everyone
Confirmation biases
From human nature, we try to run

You can run but you can’t hide!
Our biases remain
But evidence has verified
There’s knowledge we can gain

Predictive Processing: Unlocking the Mysteries of Mind & Body (Part V)

In the previous post, part 4 in this series on Predictive Processing (PP), I explored some aspects of reasoning and how different forms of reasoning can be built from a foundational bedrock of Bayesian inference (click here for parts 1, 2, or 3).  This has a lot to do with language, but I also claimed that it depends on how the brain is likely generating new models, which I think is likely to involve some kind of natural selection operating on neural networks.  The hierarchical structure of the generative models for these predictions as described within a PP framework, also seems to fit well with the hierarchical structure that we find in the brain’s neural networks.  In this post, I’m going to talk about the relation between memory, imagination, and unconscious and conscious forms of reasoning.

Memory, Imagination, and Reasoning

Memory is of course crucial to the PP framework whether for constructing real-time predictions of incoming sensory information (for perception) or for long-term predictions involving high-level, increasingly abstract generative models that allow us to accomplish complex future goals (like planning to go grocery shopping, or planning for retirement).  Either case requires the brain to have stored some kind of information pertaining to predicted causal relations.  Rather than memories being some kind of exact copy of past experiences (where they’d be stored like data on a computer), research has shown that memory functions more like a reconstruction of those past experiences which are modified by current knowledge and context, and produced by some of the same faculties used in imagination.

This accounts for any false or erroneous aspects of our memories, where the recalled memory can differ substantially from how the original event was experienced.  It also accounts for why our memories become increasingly altered as more time passes.  Over time, we learn new things, continuing to change many of our predictive models about the world, and thus have a more involved reconstructive process the older the memories are.  And the context we find ourselves in when trying to recall certain memories, further affect this reconstruction process, adapting our memories in some sense to better match what we find most salient and relevant in the present moment.

Conscious vs. Unconscious Processing & Intuitive Reasoning (Intuition)

Another attribute of memory is that it is primarily unconscious, where we seem to have this pool of information that is kept out of consciousness until parts of it are needed (during memory recall or or other conscious thought processes).  In fact, within the PP framework we can think of most of our generative models (predictions), especially those operating in the lower levels of the hierarchy, as being out of our conscious awareness as well.  However, since our memories are composed of (or reconstructed with) many higher level predictions, and since only a limited number of them can enter our conscious awareness at any moment, this implies that most of the higher-level predictions are also being maintained or processed unconsciously as well.

It’s worth noting however that when we were first forming these memories, a lot of the information was in our consciousness (the higher-level, more abstract predictions in particular).  Within PP, consciousness plays a special role since our attention modifies what is called the precision weight (or synaptic gain) on any prediction error that flows upward through the predictive hierarchy.  This means that the prediction errors produced from the incoming sensory information or at even higher levels of processing are able to have a greater impact on modifying and updating the predictive models.  This makes sense from an evolutionary perspective, where we can ration our cognitive resources in a more adaptable way, by allowing things that catch our attention (which may be more important to our survival prospects) to have the greatest effect on how we understand the world around us and how we need to act at any given moment.

After repeatedly encountering certain predicted causal relations in a conscious fashion, the more likely those predictions can become automated or unconsciously processed.  And if this has happened with certain rules of inference that govern how we manipulate and process many of our predictive models, it seems reasonable to suspect that this would contribute to what we call our intuitive reasoning (or intuition).  After all, intuition seems to give people the sense of knowing something without knowing how it was acquired and without any present conscious process of reasoning.

This is similar to muscle memory or procedural memory (like learning how to ride a bike) which is consciously processed at first (thus involving many parts of the cerebral cortex), but after enough repetition it becomes a faster and more automated process that is accomplished more economically and efficiently by the basal ganglia and cerebellum, parts of the brain that are believed to handle a great deal of unconscious processing like that needed for procedural memory.  This would mean that the predictions associated with these kinds of causal relations begin to function out of our consciousness, even if the same predictive strategy is still in place.

As mentioned above, one difference between this unconscious intuition and other forms of reasoning that operate within the purview of consciousness is that our intuitions are less likely to be updated or changed based on new experiential evidence since our conscious attention isn’t involved in the updating process. This means that the precision weight of upward flowing prediction errors that encounter downward flowing predictions that are operating unconsciously will have little impact in updating those predictions.  Furthermore, the fact that the most automated predictions are often those that we’ve been using for most of our lives, means that they are also likely to have extremely high Bayesian priors, further isolating them from modification.

Some of these priors may become what are called hyperpriors or priors over priors (many of these believed to be established early in life) where there may be nothing that can overcome them, because they describe an extremely abstract feature of the world.  An example of a possible hyperprior could be one that demands that the brain settle on one generative model even when it’s comparable to several others under consideration.  One could call this a “tie breaker” hyperprior, where if the brain didn’t have this kind of predictive mechanism in place, it may never be able to settle on a model, causing it to see the world (or some aspect of it) as a superposition of equiprobable states rather than simply one determinate state.  We could see the potential problem in an organism’s survival prospects if it didn’t have this kind of hyperprior in place.  Whether or not a hyperprior like this is a form of innate specificity, or acquired in early learning is debatable.

An obvious trade-off with intuition (or any kind of innate biases) is that it provides us with fast, automated predictions that are robust and likely to be reliable much of the time, but at the expense of not being able to adequately handle more novel or complex situations, thereby leading to fallacious inferences.  Our cognitive biases are also likely related to this kind of unconscious reasoning whereby evolution has naturally selected cognitive strategies that work well for the kind of environment we evolved in (African savanna, jungle, etc.) even at the expense of our not being able to adapt as well culturally or in very artificial situations.

Imagination vs. Perception

One large benefit of storing so much perceptual information in our memories (predictive models with different spatio-temporal scales) is our ability to re-create it offline (so to speak).  This is where imagination comes in, where we are able to effectively simulate perceptions without requiring a stream of incoming sensory data that matches it.  Notice however that this is still a form of perception, because we can still see, hear, feel, taste and smell predicted causal relations that have been inferred from past sensory experiences.

The crucial difference, within a PP framework, is the role of precision weighting on the prediction error, just as we saw above in terms of trying to update intuitions.  If precision weighting is set or adjusted to be relatively low with respect to a particular set of predictive models, then prediction error will have little if any impact on the model.  During imagination, we effectively decouple the bottom-up prediction error from the top-down predictions associated with our sensory cortex (by reducing the precision weighting of the prediction error), thus allowing us to intentionally perceive things that aren’t actually in the external world.  We need not decouple the error from the predictions entirely, as we may want our imagination to somehow correlate with what we’re actually perceiving in the external world.  For example, maybe I want to watch a car driving down the street and simply imagine that it is a different color, while still seeing the rest of the scene as I normally would.  In general though, it is this decoupling “knob” that we can turn (precision weighting) that underlies our ability to produce and discriminate between normal perception and our imagination.

So what happens when we lose the ability to control our perception in a normal way (whether consciously or not)?  Well, this usually results in our having some kind of hallucination.  Since perception is often referred to as a form of controlled hallucination (within PP), we could better describe a pathological hallucination (such as that arising from certain psychedelic drugs or a condition like Schizophrenia) as a form of uncontrolled hallucination.  In some cases, even with a perfectly normal/healthy brain, when the prediction error simply can’t be minimized enough, or the brain is continuously switching between models, based on what we’re looking at, we experience perceptual illusions.

Whether it’s illusions, hallucinations, or any other kind of perceptual pathology (like not being able to recognize faces), PP offers a good explanation for why these kinds of experiences can happen to us.  It’s either because the models are poor (their causal structure or priors) or something isn’t being controlled properly, like the delicate balance between precision weighting and prediction error, any of which that could result from an imbalance in neurotransmitters or some kind of brain damage.

Imagination & Conscious Reasoning

While most people would tend to define imagination as that which pertains to visual imagery, I prefer to classify all conscious experiences that are not directly resulting from online perception as imagination.  In other words, any part of our conscious experience that isn’t stemming from an immediate inference of incoming sensory information is what I consider to be imagination.  This is because any kind of conscious thinking is going to involve an experience that could in theory be re-created by an artificial stream of incoming sensory information (along with our top-down generative models that put that information into a particular context of understanding).  As long as the incoming sensory information was a particular way (any way that we can imagine!), even if it could never be that way in the actual external world we live in, it seems to me that it should be able to reproduce any conscious process given the right top-down predictive model.  Another way of saying this is that imagination is simply another word to describe any kind of offline conscious mental simulation.

This also means that I’d classify any and all kinds of conscious reasoning processes as yet another form of imagination.  Just as is the case with more standard conceptions of imagination (within PP at least), we are simply taking particular predictive models, manipulating them in certain ways in order to simulate some result with this process decoupled (at least in part) from actual incoming sensory information.  We may for example, apply a rule of inference that we’ve picked up on and manipulate several predictive models of causal relations using that rule.  As mentioned in the previous post and in the post from part 2 of this series, language is also likely to play a special role here where we’ll likely be using it to help guide this conceptual manipulation process by organizing and further representing the causal relations in a linguistic form, and then determining the resulting inference (which will more than likely be in a linguistic form as well).  In doing so, we are able to take highly abstract properties of causal relations and apply rules to them to extract new information.

If I imagine a purple elephant trumpeting and flying in the air over my house, even though I’ve never experienced such a thing, it seems clear that I’m manipulating several different types of predicted causal relations at varying levels of abstraction and experiencing the result of that manipulation.  This involves inferred causal relations like those pertaining to visual aspects of elephants, the color purple, flying objects, motion in general, houses, the air, and inferred causal relations pertaining to auditory aspects like trumpeting sounds and so forth.

Specific instances of these kinds of experienced causal relations have led to my inferring them as an abstract probabilistically-defined property (e.g. elephantness, purpleness, flyingness, etc.) that can be reused and modified to some degree to produce an infinite number of possible recreated perceptual scenes.  These may not be physically possible perceptual scenes (since elephants don’t have wings to fly, for example) but regardless I’m able to add or subtract, mix and match, and ultimately manipulate properties in countless ways, only limited really by what is logically possible (so I can’t possibly imagine what a square circle would look like).

What if I’m performing a mathematical calculation, like “adding 9 + 9”, or some other similar problem?  This appears (upon first glance at least) to be very qualitatively different than simply imagining things that we tend to perceive in the world like elephants, books, music, and other things, even if they are imagined in some phantasmagorical way.  As crazy as those imagined things may be, they still contain things like shapes, colors, sounds, etc., and a mathematical calculation seems to lack this.  I think the key thing to realize here is the fundamental process of imagination as being able to add or subtract and manipulate abstract properties in any way that is logically possible (given our current set of predictive models).  This means that we can imagine properties or abstractions that lack all the richness of a typical visual/auditory perceptual scene.

In the case of a mathematical calculation, I would be manipulating previously acquired predicted causal relations that pertain to quantity and changes in quantity.  Once I was old enough to infer that separate objects existed in the world, then I could infer an abstraction of how many objects there were in some space at some particular time.  Eventually, I could abstract the property of how many objects without applying it to any particular object at all.  Using language to associate a linguistic symbol for each and every specific quantity would lay the groundwork for a system of “numbers” (where numbers are just quantities pertaining to no particular object at all).  Once this was done, then my brain could use the abstraction of quantity and manipulate it by following certain inferred rules of how quantities can change by adding to or subtracting from them.  After some practice and experience I would now be in a reasonable position to consciously think about “adding 9 + 9”, and either do it by following a manual iterative rule of addition that I’ve learned to do with real or imagined visual objects (like adding up some number of apples or dots/points in a row or grid), or I can simply use a memorized addition table and search/recall the sum I’m interested in (9 + 9 = 18).

Whether we consider imagining a purple elephant, mentally adding up numbers, thinking about what I’m going to say to my wife when I see her next, or trying to explicitly apply logical rules to some set of concepts, all of these forms of conscious thought or reasoning are all simply different sets of predictive models that I’m simply manipulating in mental simulations until I arrive at a perception that’s understood in the desired context and that has minimal prediction error.

Putting it all together

In summary, I think we can gain a lot of insight by looking at all the different aspects of brain function through a PP framework.  Imagination, perception, memory, intuition, and conscious reasoning fit together very well when viewed as different aspects of hierarchical predictive models that are manipulated and altered in ways that give us a much more firm grip on the world we live in and its inferred causal structure.  Not only that, but this kind of cognitive architecture also provides us with an enormous potential for creativity and intelligence.  In the next post in this series, I’m going to talk about consciousness, specifically theories of consciousness and how they may be viewed through a PP framework.

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

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?

Dreams, Dialogue, and the Unconscious

It has long been believed that our mental structure consists of both a conscious and an unconscious element.  While the conscious element has been studied exhaustively, there seems to be relatively little known about the unconscious.  We can certainly infer that it exists as every part of the self that we can’t control or are not aware of must necessarily be mediated by the unconscious.  To be sure, the fields of neuroscience and psychology (among others) have provided a plethora of evidence related to the unconscious in terms of neuronal structures and activity, and the influence it has on our behavior, respectively.  However, trying to actually access the unconscious mind has proven to be quite difficult.  How can one hope to access this hidden yet incredibly powerful portion of themselves?  In this post, I plan to discuss what I believe to be two effective ways with which we can learn more about ourselves and access that which seems to elude us day-in and day-out.

Concept of Self

It is clear that we have an idea of who we are as individuals.  We consciously know what many of our interests are, what our philosophical and/or religious beliefs are, and we also have a subjective view of what we believe to be our personality traits.  I prefer to define this aspect of the self as the “Me”.  In short, the “Me” is the conscious subjective view one holds about themselves.

Another aspect of the self is the “You”, or the way others see you from their own subjective perspective.  It goes without saying that others view us very differently than we view ourselves.  People see things about us that we just don’t notice or that we deny to be true, whether they are particular personality traits or various behavioral tendencies.  Due to the fact that most people put on a social mask when they interact with others, the “You” ends up including not only some real albeit unknown aspects of the self, but also how you want to be seen by others and how they want to see you.  So I believe that the “You” is the social self — that which is implied by the individual and that which is inferred by another person.  I believe that the implied self and the inferred self involve both a conscious and unconscious element from each party, and thus the implication and inference will generally be quite different regardless of any of the limitations of language.

Finally, we have the aspect of the self which is typically unreachable and seems to be operating in the background.   I believe that this portion of the self ultimately drives us to think and behave the way we do, and accounts for what we may describe to be a form of “auto-pilot”.  This of course is the unconscious portion of the self.  I would call this aspect of the self the “I”.  In my opinion, it is the “I” that represents who we really are as a person (independent of subjective perspectives), as I believe everything conscious about the self is ultimately derived from this “I”.  The “I” includes the beliefs, interests, disinterests, etc., that we are not aware of yet are likely to exist based on some of our behaviors that conflict with our conscious intentions.  This aspect in particular is what I would describe as the objective self, and consequently it is that which we can never fully access or know about with any certainty.

Using the “You” to Access the “I”

I believe that the “You” is in fact a portal to access the “I”, for the portion of this “You” that is not derived from one’s artificial social mask will certainly contain at least some truths about one’s self that are either not consciously evident or are not believed by the “Me” to be true, even if they are in fact true.  Thus, in my opinion it is the inter-subjective communication with others that allows us to learn more about our unconscious self than any other method or action.  I also believe that this in fact accounts for most of the efficacy provided by mental health counseling.  That is, by having a discourse with someone else, we are getting another subjective perspective of the self that is not tainted with our own predispositions.  Even if the conversation isn’t specifically about you, by another person simply sharing their subjective perspective about anything at all, they are providing you with novel ways of looking at things, and if these perspectives weren’t evident in your conscious repertoire, they may in fact probe the unconscious (by providing recognition cues for unconscious concepts or beliefs).

The key lies in analyzing those external perspectives with an open mind, so that denial and the fear of knowing ourselves do not dominate and hinder this access.  Let’s face it, people often hear what they want to hear (whether about themselves or anything else for that matter), and we often unknowingly ignore the rest in order to feel comfortable and secure.  This sought-out comfort severely inhibits one’s personal growth and thus, at least periodically, we need to be able to depart from our comfort zone so that we can be true to others and be true to ourselves.

It is also important for us to strive to really listen to what others have to say rather than just waiting for our turn to speak.  In doing so, we will gain the most knowledge and get the most out of the human experience.  In particular, by critically listening to others we will learn the most about our “self” including the unconscious aspect.  While I certainly believe that inter-subjective communication is an effective way for us to access the “I”, it is generally only effective if those whom we’re speaking with are open and honest as well.  If they are only attempting to tell you what you want to hear, then even if you embrace their perspective with an open mind, it will not have much of any substance nor be nearly as useful.  There needs to be a mutual understanding that being open and honest is absolutely crucial for a productive discourse to transpire.  All parties involved will benefit from this mutual effort, as everyone will have a chance to gain access to their unconscious.

Another way that inter-subjective communication can help in accessing the unconscious is through mutual projection.  As I mentioned earlier, the “You” is often distorted by others hearing what they want to hear and by your social mask giving others a false impression of who you are.  However, they also tend to project their own insecurities into the “You”.  That is, if a person talking with you says specific things about you, they may in fact be a result of that person unknowingly projecting their own attributes onto you.  If they are uncomfortable with some aspect of themselves, they may accuse you of possessing the aspect, thus using projection as a defense mechanism.  Thus, if we pay attention to ourselves in terms of how we talk about others, we may learn more about our own unconscious projections.  Fortunately, if the person you’re speaking with knows you quite well and senses that you are projecting, they may point it out to you and vice versa.

Dream Analysis

Another potentially useful method for accessing the unconscious is an analysis of one’s dreams.  Freud, Jung and other well-known psychologists have endorsed this method as an effective psychoanalytic tool.  When we are dreaming, our brain is in a reduced-conscious if not unconscious state (although the brain is highly active within the dream-associated REM phase).  I believe that due to the decreased sensory input and stimulation during sleep, the brain has more opportunities to “fill in the blanks” and make an alternate conceptualization of reality.  This may provide a platform for unconscious expression.  When our brain constructs the dream content it seems to be utilizing a mixture of memories, current sensory stimuli constituting the sleeper’s environment (albeit a minimal amount — and perhaps necessarily so), and elements from the unconscious.  By analyzing our dreams, we have a chance to try and interpret symbolic representations likely stemming from the unconscious.  While I don’t believe that we can ever know for sure that which came from the unconscious, by asking ourselves questions relating to the dream content and making a concerted effort to analyze the dream, we will likely discover at least some elements of our unconscious, even if we have no way of confirming the origin or significance of each dream component.

Again, just as we must be open-minded and willing to face previously unknown aspects of ourselves during the aforementioned inter-subjective experience, we must also be willing to do the same during any dream analysis.  You must be willing to identify personal weaknesses, insecurities, and potentially repressed emotions.  Surely there can be aspects of our unconscious that we’d like and appreciate if discovered, but there will likely be a tendency to repress that which we find repulsive about ourselves.  Thus, I believe that the unconscious contains more negative things about our self than positive things (as implied by Jung’s “Shadow” archetype).

How might one begin such an analysis?  Obviously we must first obtain some data by recording the details of our dreams.  As soon as you wake up after a dream, take advantage of the opportunity to record as many details as you can in order to be more confident with the analysis.  The longer you wait, the more likely the information will become distorted or lost altogether (as we’ve all experienced at one time or another).  As you record these details, try and include different elements of the dream so that you aren’t only recording your perceptions, but also how the setting or events made you feel emotionally.  Note any ambiguities no matter how trivial, mundane, or irrelevant they may seem.  For example, if you happen to notice groups of people or objects in your dreams, try to note how many there are as that number may be significant.  If it seems that the dream is set in the past, try to infer the approximate date.  Various details may be subtle indicators of unconscious material.

Often times dreams are not very easy to describe because they tend to deviate from reality and have a largely irrational and/or emotional structure.  All we can do is try our best to describe what we can remember even if it seems non-sensical or is difficult to articulate.

As for the analysis of the dream content, I try and ask myself specific questions within the context of the dream.  The primary questions include:

• What might this person, place, or thing symbolize, if they aren’t taken at face value?  That is, what kinds of emotions, qualities, or properties do I associate with these dream contents?
• If I think my associations for the dream contents are atypical, then what associations might be more common?  In other words, what would I expect the average person to associate the dream content with?  (Collective or personal opinions may present themselves in dreams)

Once these primary questions are addressed, I ask myself questions that may or may not seem to relate to my dream, in order to probe the psyche.  For example:

• Are there currently any conflicts in my life? (whether involving others or not)
• If there are conflicts with others, do I desire some form of reconciliation or closure?
• Have I been feeling guilty about anything lately?
• Do I have any long term goals set for myself, and if so, are they being realized?
• What do I like about myself, and why?
• What do I dislike about myself, and why?  Or perhaps, what would I like to change about myself?
• Do certain personality traits I feel I possess remind me of anyone else I know?  If so, what is my overall view of that person?
• Am I envious of anyone else’s life, and if so, what aspects of their life are envied?
• Are there any childhood experiences I repeatedly think about (good or bad)?
• Are there any recurring dreams or recurring elements within different dreams?  If so, why might they be significant?
• Are there any accomplishments that I’m especially proud of?
• What elements of my past do I regret?
• How would I describe the relationships with my family and friends?
• Do I have anyone in my life that I would consider an enemy?  If so, why do I consider them an enemy?
• How would I describe my sexuality, and my sex life?
• Am I happy with my current job or career?
• Do I feel that my life has purpose or that I am well fulfilled?
• What types of things about myself would I be least comfortable sharing with others?
• Do I have undesired behaviors that I feel are out of my control?
• Do I feel the need to escape myself or the world around me?  If so, what might I be doing in order to escape? (e.g. abusing drugs, abusing television or other virtual-reality media, anti-social seclusion, etc.)
• Might I be suffering from some form of cognitive dissonance as a result of me having conflicting values or beliefs?  Are there any beliefs which I’ve become deeply invested in that I may now doubt to be true, or that may be incompatible with my other beliefs?  If the answer is “no”, then I would ask:  Are there any beliefs that I’ve become deeply invested in, and if so, in what ways could they be threatened?

These questions are intended to probe one’s self beneath the surface.  By asking ourselves specific questions like this, particularly in relation to our dream contents, I believe that we can gain access to the unconscious simply by addressing concepts and potential issues that are often left out-of-sight and out-of-mind.  How we answer these questions isn’t as important as asking them in the first place.  We may deny that we have problems or personal weaknesses as we answer these questions, but asking them will continue to bring our attention to these subjects and elements of ourselves that we often take for granted or prefer not to think about.  In doing so, I believe one will at least have a better chance at accessing the unconscious than if they hadn’t made an attempt at all.

In terms of answering the various questions listed above, the analysis will likely be more useful if you go over the questions a second time, and reverse or change your previous instinctual answer while trying to justify the reversal or change.  This exercise will force you to think about yourself in new ways that might improve access to the unconscious, since you are effectively minimizing the barriers brought on through rationalization and denial.

Final Thoughts

So as we can see, while the unconscious mind may seem inaccessible, there appear to be at least two ways with which we can gain some access.  Inter-subjective communication allows us access to the “I” via the “You”, and access to both the speaker’s and the listener’s unconscious is accomplished via mutual projection.  Dreams and the analysis of such appears to be yet another method for accessing the unconscious.  Since our brains appear to be in a semi-conscious state, the brain may be capable of cognitive processes that aren’t saturated by sensory input from the outside world.  This reduction in sensory input may in fact give the brain more opportunities to “fill in the blanks” (or so to speak), and this may provide a platform for unconscious expression.  So in short, it appears that there are at least a few effective methods for accessing the unconscious self.  The bigger question is:  Are we willing to face this hidden side of ourselves?
