Upon first learning about determinism, specifically scientific determinism, I became quite anxious and internally divided given the importance I had previously placed on free will. I weighed in the strengths and weaknesses of both sides, and ultimately it was determinism that emerged as the clear winner, at least from my point of view. The idea that I have no free will seemed despairing at first, but upon further investigation I realized that as contradictory as it may seem, free will and determinism can work in conjunction.
First, an outline of determinism is in order. Broadly defined, determinism is the idea that the current universal state of affairs - all events, actions, and decisions - is determined by a previous state of affairs, in effect implying that free will is illusory. Determinism can then be further broken down into categories such as social determinism, economic determinism, environmental determinism, and so forth. The specific type of determinism that caught my attention, and which I believe to be reductionist and therefore to render all other forms of determinism irrelevant, is scientific determinism. Materialism, the view that everything is made up of matter and energy, which follow the universal laws of nature, creates the basis of and in fact necessarily implies scientific determinism.
I’ll state now that for many years I’ve retained an agnostic viewpoint of religion/higher powers for one simple reason: I believe that it would require a great level either of intelligence or of arrogance, neither of which I possess at sufficient levels, to state that it can be proven that the existence of some type of higher power does not exist. Furthermore, I have my doubts that any kind of ultimate Truth can truly be known. That being said, my metaphysical viewpoint on what I believe to probably be the case is a nihilistic one, but more on that another time.
Now, back to the argument at hand. As a result of my underlying view of reality, that all is made up of matter following the universal laws of nature/physics, I find the argument for scientific determinism quite convincing. If I believe that I am a product of evolution, my species having started out countless generations ago as a single cell organism, and further back yet on the molecular level as different atoms travelling on their determined paths and then coming together to form molecules; if I am an extremely complex organism, whose systems can be broken down further and further until reduced to these same interactions on the molecular and atomic levels, then what room does that leave for free will? Some would make the argument that mind/body dualism, the view that there is a separate physical body and nonphysical mind, is able to account for free will, but I have yet to hear a convincing argument for dualism. For instance, how do the physical and non-physical interact? How might a dualist explain the correlation between damage to the brain and the resulting change in mental function, or the neuro-chemical effects of drugs on the non-physical mind? Alas, if one believes in universal scientific law, then one necessarily believes in determinism.
One exception or possible alternative to the ontological concept of scientific determinism is that suggested by quantum physics. If we were to reduce our argument of determinism at the atomic level yet further down into the sub-atomic level, quantum physicists would suggest that things start to act a little strange and not in accordance with the practical laws of science; substances can exist in multiple locations at once, as both particles or waves, and react in quite unpredictable ways. I find this idea certainly to work well against the concept of scientific determinism, but it also still works against the concept of free will, at least in most cases. Some physicists, such as Roger Penrose, argue that consciousness exists in a sort of quantum form at the fundamental level of the universe and that it is tapped into by our neurons and cannot be simulated artificially, a theory worth reading into but which I’m not convinced by, as at this point I maintain a more functionalist viewpoint on the philosophy of mind. But alas, I digress.
I believe a further distinction needs to be made between determinism and fatalism. Fatalism, generally speaking, is the concept that our destinies are pre-determined by a higher power, and that nothing can be done to change this. Determinism, on the other hand, doesn’t necessarily predict what will happen; it merely claims that the current state of affairs is the result of a previous state of affairs. I might argue that they are more similar than others would admit, with the exception of the involvement of a higher power in fatalism. Imagine though, if it was possible to take a universal snapshot of the current state of all things. Given an intellect of infinite capacity and using the universal laws of nature, would it not be possible to map out the indefinite history of all things?
If at all convinced by the argument for scientific determinism, it seems to eliminate the possibility for free will. But despair ye not! It turns out that free will and determinism can both fit into one’s worldview, with the help of pragmatism. For instance, if I’m standing on a train track and a train is coming at me, I will not simply say to myself, “I don’t need to get out of the way. All is determined, so if it so happens that the complex machine I call my body decides not to move, then so be it.” No, I see the train and I make what feels like a decision to get out of the way, even if that ‘decision’ is a mere illusion, covering the complex interaction between stimulus, processing, and response on the higher level, neural computation on the mid-level, and biophysical cause & effect on the low-level. I can believe that my actions and thoughts are entirely determined, but that does not mean I’m going to refrain from behaving as though I have free will. Some would say that this concept, this pragmatic cohesion between determinism & free will, is quite important in upholding the way in which we behave and are responsible for our actions, and in maintaining the very foundations of society. It puts the complex machine of my brain at ease to know that I can be a scientific determinist and an existentialist at the same time.
