By now we’ve all noticed the campaign of scientific materialists to discredit religion in the hope that a saner, more scientific society will prevail. This future society, it is hoped, will base decisions on empirically verifiable facts and not superstition. Among those leading the campaign for atheism are Richard Dawkins, the late Christopher Hitchens, Bill Maher, Ricky Gervais, and the co-founder of Project Reason, philosopher and neuroscientist Sam Harris.

"Free Will" by Sam HarrisHarris’ position is very clear: he believes that physics explains all phenomena and therefore our so-called free will is actually an illusion. Because the decisions we make arise out of our current conditions, and those conditions are the result of innumerable physical influences (brain structure, weather, etc.), our decisions are simply the outcome of a specific organism (us) going through a specific physical history (everything that formed us).

Looking back at any action, it is easy to feel as though we could have done things differently. But we cannot prove this. To say we could have acted differently is to suppose that at least some condition at the time of our decision would have been different. If not for the particular conditions influencing us, why did we decide as we did?

Free Will acknowledges the psychological fact that we all feel we are in control of our decisions. This is, in reality, one of the very few arguments for free will. So Harris asks us to look into the causes of our future decisions. We can tell a story about what influences us and how we will likely act, but this story covers very few of the innumerable factors that actually move us to one action over another. When we finally make a decision and exercise our will, we cannot say the impetus lies solely with our conscious “I.”

The conscious “I,” Harris argues, is a simply a function of human organisms. Consciousness is necessary to sort priorities and make decisions, but no supernatural agency is needed to justify this; it is simply an adaptive biological function. Willpower, he claims, is one factor of our consciousness, and we can never truly know why we choose to do one thing over another.

With Harris’ position, there is no need to invent supernatural explanations for any of the facts. God and the soul are comforting fictions but cannot maintain in a society that bases its decisions on empirical data.  

This book should be fairly convincing to anyone with an open mind. I empathize with the frustration that theists must feel at the disrespect with which many writers and celebrities criticize religion. But Harris is not belligerent at all. His writing is clear, cogent, and makes no unnecessary detours to put down any creed. He instead prefers a straightforward approach, written in firm language.

Far from abstract verbalism, Free Will discusses the practical issues of morality, politics, and justice without yanking the rug out from under them. From Harris’ position justice must still be served, but our inclinations to hate criminals must be reassessed as we realize these criminals aren’t in complete control, but are the unlucky outcomes of bad genes, bad environments, or other maladaptive conditions. The elimination of free will in no way leads to the decay of morality.

What really impresses me about Free Will is the logical, masterful way in which he unfolds his thesis. Many times I finished one chapter with specific questions, only to find those exact questions tackled in the next chapter. Whether the reader is convinced or not, the execution of this little book is far superior to most on the subject.

    Logical? Hardly. It’s an absurdity.

    Q: Is your belief that “free will is an illusion” based on logic, or brain chemistry?

    If it is based on logic, then congratulations! You alone, among all humans who have ever lived, actually possess the free will to veto the dictates of your own brain chemistry. Can I have your autograph?

    If, on the other hand, your belief is based on brain chemistry, then it is not based on logic and therefore there is no paticular reason to suppose it’s true (adaptive, perhaps, but not reliably true, even if your brain chemistry compels you to believe it’s true).

    The assertion that “free will is an illusion”, then, is a self-refuting statement based on breathtaking intellectual vanity. Even it were true, there is no way we could ever know it’s true. We could only “believe” it, and even then only for as long as our brain chemistry compels us to believe it.
