Our default fundamental philosophical positions often seem to be the most sensible , and they are further reinforced by institutions, such as a prevailing religion, that wield influence over a culture. However, upon closer inspection and introspection, one perhaps finds that which was once as reasonable as the idea that the sun rotates around the earth replaced by non-intuitive truths such as heliocentrism.
The attribute most closely held by virtually all, and the one seen as that which most separates us from the animal kingdom, is that we are imbued with libertarian free-will, that our decisions are ours alone, enacted without interior coercion. Though our choices may not be absolutely unbridled by circumstance, at very least, our moral choices are enacted by some perhaps innate divine spark.
Just as Copernicus supplanted the Ptolemaic system, I would affirm that neuroscience, as well as classical physics, as supplanted libertarian metaphysics. We live in a universe, at least above the quantum level, that is governed by causality, often complex and nuanced, especially in respect to human behavior. The brain, as with all biological organs, is bound by the laws of nature, by chemistry, biology. As such, our identity, our sense of person-hood, our consciousness, is an emergent property of the brain, though the mechanism is perhaps dimly understood at the present time. What is known, though, is that our behaviors, our very identity, are effected by changes to the brain, either by illness, injury, or intake of mind altering substances.
Well documented is the fact that our moral proclivities can be altered by the effects on the brain by a benign tumor. It is undeniable that the core of ones personality can be permanently altered by injury to the brain. One of the foundations of our sense of self, our memories, may be erased by the terrible onslaught of dementia. Even our political leanings can be predicted by variations in brain structure. It is noted that self-identified liberals tend to have a larger anterior cingulate cortex (ACC) while those who identify as conservative have a larger amygdala. Parenthetically, the ACC, amongst other functions, is related to coping with uncertainty and monitoring conflicting information while a larger amygdala is linked have a greater sensitivity to fear and disgust.
How the aforementioned relates to the debate over free will vs determinism should begin to become clear. An experiment by Benjamin Libet, performed in the 1980’s and repeated afterwards, seems to affirm the deterministic principle of materialism in relation to human behavior. In Libet’s experiment, participants were to perform a simple action, pressing a button, for example, and were asked to note the instant in time when they were consciously aware of their decision to perform the action. In the experiment, EEG electrodes were attached to the participants head, and interestingly, it was noted that certain brain activity, referred to by Libet as a ‘readiness potential,’ occurred on average a half-second before the participants were aware of their decision to act. The point of the above is that often decisions are made in the unconscious mind before they bubble up to the level of awareness.
Let’s think further about how our choices are constrained, perhaps to the point that they are only an illusion of choice. Think of the powerful influences over our preferences and attributes of which we have no control. We did not chose the time and place of our birth. We did not chose the color of our eyes, nor the biological gender we were assigned at birth. We did not chose the politics or religion of our parents, cultural influences that color, at the very least, our years into young adulthood. Even our hobbies and interests are informed by parents and culture. I’ve known many avid hunters over the years, and one common thread is that hunting has been a family tradition spanning generations. Would an individual with no exposure to such suddenly wake up one morning and decide to nurture an interest in killing dear?
Being an avid reader with a wide range of interests. I have, at times, revisited novels read years ago, and much like viewing a movie for the second time, the denouement remains the same. If we were to rewind our life to a point in our history were we have made a decision, of consequence or not, I believe, our narrative experience would not change because the myriad of causes that effected said decision remains the same.
I am aware of the rather brief and superficial nature of my treatment of the subject and it’s consequences, but as I think more about thinking, about those hidden places where thoughts, often unpredictable, emerge, I found myself having abandoned the comfortable notion that we possess a divine spark that gives birth to free will. Even in my days of Christian zealotry, I affirmed the Biblical text revealed a story of an Abrahamic god who was no respecter of His creations ‘free will’, hardening the hearts of some at His whim, and opening others when He desired. In the Creation myth, we find mankind in a fallen state where one cannot even chose to be morally perfect, that a state of falleness is our inheritance. And what about morals without a foundation of free will? Briefly, I am now more nuanced in my ideas and thoughts of justice and punishment, more compassionate of all, overall. I know that there are causes for behaviors, and I believe less in being punitive towards bad actors and lean more into rehabilitation. If such is not possible, then humanly segregate those unable to function in society. My hope is that as we progress into the 21st century, we shed archaic concepts and grow more humane.
