Sam Harris, philosopher and neuroscientist, writes this treatise on Free Will from an incompatibilist view point. Most theologians and many philosophers today take the compatibilist approach, which is the view that determinism (we have no control over causal events) is compatible with the idea of free will. Harris makes out a forceful argument that this is not so. He believes that free will is an illusion. Citing the fact that "No human being is responsible for his genes or his upbringing, yet we have every reason to believe that these factors determine his character" to illustrate his point that we mistake conscious deliberations for free will. He asks, for example, if his decision to have a second cup of coffee was due to a random release of neurotransmitters, how could the indeterminacy of the initiating event count as an exercise of free will? If he drank a glass of water because he was thirsty, even though he was free to choose orange juice, it could hardly be an exercise of free will if the thought of an orange juice never crossed his mind. He goes further and suggests that even if we were to believe in a "soul" that dwells within us, we cannot be exercising free will - "if we have no idea what [our] soul is going to do next, [we] are not in control." Harris does not believe that determinism necessarily leads to fatalism and he explains so in pages 33-35. He also believes that belief in determinism "need not damage our system of criminal justice." (see pages 56-60). He concludes his book thus: "Now I feel that it is time for me to leave. I'm hungry, yes, but it also seems that I've made my point. In fact, I can't think of anything else to say on the subject. And where is the freedom in that?"
