Philosophical Naturalism (Self-Stultifying) | CS LEWIS

This is an excerpt from C.S. Lewis' book, "God in the Dock," chapter 4 -- Answers to Questions on Christianity.

EXTRA
Determinism is self-stultifying. If my mental processes are totally determined, I am totally determined either to accept or to reject determinism. But if the sole reason for my believing or not believing X is that I am causally determined to believe it I have no ground for holding that my judgment is true or false.

ROBOTS AND COSMIC PUPPETRY: THE SCIENTIFIC CHALLENGE TO FREEDOM

Since at least the time of Sir Isaac Newton, scientists and philosophers impressed by the march of science have offered a picture of human behavior that is not promising for a belief in freedom. All nature is viewed by them as one huge mechanism, with human beings serving as just parts of that giant machine. On this view, we live and think in accordance with the same laws and causes that move all other physical components of the universal mechanism.

According to these thinkers, everything that happens in nature has a cause. Suppose then that an event occurs, which, in context, is clearly a human action of the sort that we would normally call free. As an occurrence in this universe, it has a cause. But then that cause, in turn, has a cause. And that cause in turn has a cause, and so on, and so on [remember, reductionism].

➤ “Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible player” ~ Albert Einstein.

As a result of this scientific world view, we get the following picture:

✦ Natural conditions outside our control…
✦ cause…
✦ Inner bodily and brain states,
✦ which cause…
✦ mental and physical actions

But if this is true, then you are, ultimately, just a conduit or pipeline for chains of natural causation that reach far back into the past before your birth and continue far forward into the future after your death. You are not an originating cause of anything [this includes brain activity of all degrees, that is, love, pain, etc.). Nothing you ever do is due to your choices or thoughts alone. You are a puppet of nature. You are no more than a robot programmed by an unfeeling cosmos.

Psychologists talk about heredity and environment as responsible for everything you do. But then if they are, you aren’t. Does it follow that you can then do as you please, irresponsibly? Not at all. It only follows that you will do as nature and nurture please. But then, nature on this picture turns out to be just an illusory veil over a heartless, uncaring nature. You have what nature gives you. Nothing more, nothing less.

Where is human freedom in this picture? It doesn’t exist. It is one of our chief illusions. The natural belief in free will is just a monstrous falsehood. But we should not feel bad about holding on to this illusion until science corrects us. We can’t have helped it.

This reasoning is called The Challenge of Scientific Determinism. According to determinists, we are determined in every respect to do everything that we ever do.

This again is a serious challenge to human freedom. It is the reason that the early scientist Pierre Laplace (1749-1827) once said that if you could give a super-genius a total description of the universe at any given point in time, that being would be able to predict with certainty everything that would ever happen in the future relative to that moment, and retrodict with certainty anything that had ever happened in any moment before that described state. Nature, he believed, was that perfect machine. And we human beings were just cogs in the machine, deluded in our beliefs that we are free.
