It has been over a year since my last entry. I've sat down on a couple of different occasions in that time and tried to compose the next installment, but until now, it wouldn't come. I knew the subject, but just what I had to say about it remained cognitively ethereal, and it has taken until now for it to coalesce to the point where I'm confident that, yes, a clear, solid set of thoughts has indeed sprung into existence. I'd like to try and share the cardinal points of this year long journey with you now. This will be the last installment of Qjapheme, and something new will take its place. It has served its purpose for me these last five years, and for all my initial skepticism about keeping a blog, I've come to understand and appreciate the value of information, even terribly obscure, often esoteric ramblings in the ephemeral, electronic format.
I'd like to give trial basis to a particular definition of 'belief': the act of allowing the mind to accept a given idea or concept as true to such a degree that the physiological response to the idea or concept is indistinguishable from other truths.
Already I can see things getting tangled in semantical netting here, but fortunately I am not limited to one dictionary-esque definition to illustrate my meaning. I have not rigorously researched the topic I'm about to speak on, but I've been fortunate enough to have been exposed to the writings of some who have: Carl Sagan, Francis Collins, Michael Shermer being the latest and most lucid. I'd like to thank them for their work, and everyone else who grapples with our biggest existential mysteries with such courage and dedication.
As I have come to understand it, as human creatures we have a peculiar relationship with 'the truth'. Apprehending reality in a consistent and predictable way is essential to our well being. Being unable to reliably perceive the truth, or more commonly, facing deception, typically elicits a stress response from our bodies. Why? The simplest answer I think is obvious: If we lack true information, suffering can easily follow. If I can't find food, I'll starve. If I'm unaware of danger, it can harm me. This is true of every living thing. As complex social creatures, these most basic needs manifest in humans as networks of trust.
The most important consideration amidst all this is one I think religion and science both point out: we are fallible, but this can be overcome. In the Abrahamic faiths (Judaism, Christianity, Islam), this fallibility is sin, and is overcome by faith in God. In Buddhism, the fallibility is our resistance to change, and it is overcome by letting go of the self and accepting change. Science, in particular neuroscience, the study of the brain, has put forth an explanation of this fallibility to which I am partial because of its robust and harmonious explanatory power amidst so many different angles of examination.
Our brains being a product of biological evolution is central to this. Brains are not computer programs which have benefitted from concentrated debugging efforts. Instead, the brain's capabilities and its bugs arise from slow, gradual transformations which deal with challenges that are being faced at a particular point in time. The human body has many vestigial components - remnants of things that once made sense to have, but are no longer needed. The muscles that allow you to wiggle your ears are left overs from when ear directionality was important to hearing (like dogs, cats, horses, etc. all point their ears towards what they want to listen to). The nerve that connects your brain to your vocal chords curiously loops down near your heart, a result of the pathway elongating, but evolution being unable to 'unplug, detangle, and replug' the nerve back in like we do when a mess of electrical cords needs sorting out behind our electronics. Even our DNA contains ARE's or Ancient Repetitive Elements which are also found in other mammals (even mice) but aren't expressed in our genome. They were needed once, but not anymore, and evolution doesn't use a Trash or Recycle Bin like you would on your computer desktop.
Our brains have trillions of pathways which serve to code our very complex experiences and behaviors. There are even synapses that only fire when we see a particular individual's face. At its most basic though, the brain is a difference engine: pathways are either on, or off. The operation of what gets turned on and what gets turned off has also fallen under the inevitable guidance of our most basic needs: feeling of hunger indicates that it's time to acquire food; injections of adrenaline into the system indicate a time to fight or run; feelings of sexual attraction are the brain's way of using pleasure hormones to reward a behavior that propagates the species, without which no new brains ever come to exist at all.
Assessments of truth and falsity also fall under the brain's list of tasks (as do all tasks we perform, whether conscious or unconscious, our brain orchestrates everything, evidenced by the fact that if the brain is damaged in a particular area, that area's tasks are impeded, or eliminated). And this is where science explains our fallibility: here the brain makes mistakes. It can make false positives and false negatives, perceiving something as true when it is not, and also perceiving something as false when it is true. In this way, the brain believes instead of knows. And if we look back to our definition of belief, the effect of a belief that something is true is physiologically indistinguishable from something that is known to be true. Belief is just un-vetted knowledge, and it can be objectively correct or incorrect.
We all dream, and we all know dreams can seem indistinguishable from reality. A friend of mine actually told me about a dream he had which seemed to span an entire day, and because of events that happened in the dream, he was angry with his mother for a week for something that never actually happened. Similarly, schizophrenia is characterized partially by the brain accepting as true things which objectively aren't, usually resulting in symptoms of hallucinations, paranoia and conspiracy theorizing. The difference between dreams and schizophrenia is not that one is 'normal' and the other 'abnormal', but instead that when you wake up, dreams are usually recognized as not real, whereas a brain suffering from schizophrenia fails to properly vet the patterns that are being made. If my friend had dreams all the time that made him mad at people for things that never happened, we might say he was mentally ill, but because this is infrequent, we say he's alright. But, the potential lies inside all of us, and false positives are far more common than I ever really considered. As scary as the thought may be, this leads me to imagine that the experience of our own lives are actually based on true stories instead of simply being objectively true stories. And for the same reason that multiple witnesses make a stronger case, that we have two eyes instead of just one, and that multiple lines of evidence are required to suss out the best explanation, we need to consider as many of those lives, based on true stories, as we can when searching for answers in life.
