Materialism is the theory that matter is all
that exists. From a materialist’s perspective, all aspects of mind and
consciousness — including our thoughts, feelings, beliefs, and intentions — are
believed to result from nothing more than electrochemical impulses in our
brains. A corollary of this perspective is that many aspects of our everyday
human experience – including mental causation, free will, and our sense of self
– are mere illusions, simple by-products of our neural and bodily machinery.
The materialist viewpoint was articulated rather bluntly by Francis Crick (co-discoverer of the structure of DNA), who
said: “‘You,’ your joys and your sorrows, your memories and your ambitions,
your sense of personal identity and free will, are in fact no more than the
behavior of a vast assembly of nerve cells and their associated molecules.” Or,
as Marvin Minsky (one of the pioneers in the field of
artificial intelligence) put it: “The human brain is just a computer that
happens to be made out of meat.”
The materialist perspective contrasts rather
sharply with the religious belief that human beings are children of God. While
different religions may teach different things about exactly what it means to
be a child of God, I think it’s safe to say that most, if not all, religions
agree that humans are much more than computers made of meat.
So it’s not surprising that a religious person
like myself would be skeptical of materialism. It is, however, surprising that
someone like NYU philosophy professor Thomas Nagel would be skeptical of materialism. Nagel, you
see, is a committed atheist. He has expressed this rather forcefully, saying: “It isn’t
just that I don’t believe in God and, naturally, hope that I’m right in my
belief. It’s that I hope there is no God! I don’t want there to be a God; I
don’t want the universe to be like that.”
And yet, in his book Mind
and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost
Certainly False,
Nagel confesses that
