Physicalism (Materialism) Verifies Free Will Defining free will and physicalism The 'will' is the conscious experience of deciding and initiating human actions. Stefan Molyneux defines free will as the ability to compare an action to an ideal standard, but I will take a broader definition of free will which I would assume Stefan would agree with (without allowing for compatibilism): Free will is the ability to choose between possible actions independently of events that are external to a persons 'will'. That is, a person who decided to pursue action A at time X could have chosen action B under exactly the same external circumstances if he or she had 'willed' to do so. The opposite of free will is determinism which is: the doctrine that all events, including human action, are ultimately determined by causes regarded as external to the 'will'. Another definition of determinism is that events including the 'will' are determined by previously existing causes, however, this definition will not be used because I believe it does not necessarily touch the core of the issue which is whether our 'will' can act undetermined by external causes. If we were to assume this second definition, then determinism would be compatible with free will. Physicalism (also known as materialism) is the doctrine that the real world consists only of the physical world. The contradiction between free will and physicalism In this section, I will play devil's advocate and suggest a contradiction between free will and physicalism. Stefan argues that it is self-evident that free will exists, i.e., that our will causes human actions, as anyone arguing against this is causing their human action of 'arguing'. Not only that, but they are assuming that the other person is in a sense causing their 'listening' or 'acceptance' or 'non-acceptance' of their argument, which are also human actions. An issue with free will that probably troubles the minds of others in this community is that if free will is self-evident, it is true. If it is true, then determinism is false. If determinism is false then physicalism is false. It seems if we accept free will, we must abandon physicalism and adopt mind-body dualism, that is, that the 'will' is real but is independent of the physical world. It seems that the physical world is synonymous with objective reality because all that is objective is in some way measurable and that which is measurable is physical. However, mind-body dualism would mean that reality consists of more than objective reality, which means truth is subjective. However, the statement that 'truth is subjective' demonstrates that truth is objective, which is a contradiction. We are left in a bind. Either determinism or free will is true. Determinism must be false because free will is self-evident, and free will must be false because mind-body dualism is self-contradictory. This is a contradiction. Defending free will and physicalism I believe there is an error in the above reasoning. It does not follow that "if determinism is false then physicalism is false". In fact, I will now argue that if physicalism is true, then free will is true, and hence determinism is false. The 'will', self, or consciousness exists and this is self-evident (cogito ergo sum; I think therefore I am). Therefore, physicalism would imply that the 'will' is physical. This conclusion is in line with physicalist theories of consciousness including Integrated Information Theory (IIT) which states that a system's consciousness is determined by its causal properties and is therefore an intrinsic, fundamental property of any physical system. If physicalism is true, then consciousness is a property of the causal links between neurons in a person's neural network. Then, consciousness is identical to the neural network. They are one of the same. If consciousness is the neural network, then our 'will' is also the neural network. Determinism would suggest that human actions are caused by this neural network but that human actions are caused by events external to our 'will': Determinism would suggest that the neural network itself is determined by external events such as non-conscious 'zombie' networks or neural networks connected to but external to the brain such as the peripheral nervous system. Therefore, if our brain determines actions and our brain is determined by external events, then our actions are determined by external events. However, it is not necessarily the case that external events determine our conscious neural network. According to IIT, the neural network is causally linked in such a way that the system is more akin to a positive feedback loop than a feed-forward system. That is, rather than external events causing consciousness causing action, external events play a role in consciousness (for example, I might say the reason I drank a glass of water is that I am thirsty) but that consciousness is caused by prior consciousness. Therefore, actions would be caused by consciousness, but consciousness would not be caused by external events. And because the 'will' is synonymous with our experience of consciousness, our 'will' has self-caused the action. It is not even that non-conscious processes cause our 'will'. It is that our 'will' and indeed our 'self' is composed in that integrated neural network that plays out causes and effects with itself. This is exactly what free will is, it is the freedom of the 'will' to act without being determined by external events, and because the ‘will’ is equal to the neural networks, the neural networks don’t count as external events. The best way to describe free will would be to say that it is an endogenous system. So we must conclude that physicalism actually demonstrates that free will is true and determinism is false. Looking at it from this perspective, it is completely, both ontologically and metaphysically accurate to say that 'I' convinced myself do to action A or action B. Conclusion The conception of free will I have suggested seems to dissolve much of the worries that people have about determinism. Some may worry that if determinism is true, then how can we ever be satisfied that we act rationally or are responsible for our actions? If external events determined that I would do something irrational or evil, how are we to expect any kind of integrity from ourselves. If we cannot expect integrity from ourselves, how can we say that we are really rational animals and how can we assign responsibility to ourselves and others? It seems that if determinism is true, then we are in a way doomed to a quasi-pathological life and we are fundamentally not in control of our own happiness. I believe this is the fundamental worry among free willers. The conception of free will I suggest solves this issue by suggesting that our self-integrity lies within the physical integrity (literally the integrated information) in our neural networks that retain a self-generating, endogenous system. If we look at free will with a physicalist lense, I believe we can preserve free will without compromising physicalism.
