AWAITING A NEW GOD:

Awaiting a New Darwin : a review of Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False by Thomas Nagel (H. Allen Orr, 2/07/13, NY Review of Books)

In Mind and Cosmos, Nagel continues his attacks on reductionism. Though the book is brief its claims are big. Nagel insists that the mind-body problem "is not just a local problem" but "invades our understanding of the entire cosmos and its history." If what he calls "materialist naturalism" or just "materialism" can't explain consciousness, then it can't fully account for life since consciousness is a feature of life. And if it can't explain life, then it can't fully account for the chemical and physical universe since life is a feature of that universe. Subjective experience is not, to Nagel, some detail that materialist science can hand-wave away. It's a deal breaker. Nagel believes that any future science that grapples seriously with the mind-body problem will be one that is radically reconceived.

As Nagel makes clear in the subtitle of Mind and Cosmos, part of what he thinks must be reconceived is our reigning theory of evolutionary biology, neo-Darwinism. Neo-Darwinism maintains, or at least implies, that the origin and history of life can be explained by materialist means. Once the first life arose on earth, the fate of the resulting evolutionary lineage was, neo-Darwinists argued, shaped by a combination of random mutation and natural selection. Biological types that survive or reproduce better than others will ultimately replace those others. While natural selection ensures that species constantly adapt to the changing environments around them, the process has no foresight: natural selection responds only to the present environment and evolution cannot, therefore, be aiming for any goal. This view, Nagel tells us, is "almost certainly false."

Before creationists grow too excited, it's important to see what Nagel is not claiming. He is not claiming that life is six thousand years old, that it did not evolve, or that natural selection played no part in this evolution. He believes that life has a long evolutionary history and that natural selection had a part in it. And while he does believe that intelligent design creationists have asked some incisive questions, Nagel rejects their answers. Indeed he is an atheist. Instead Nagel's view is that neo-Darwinism, and in fact the whole materialist view elaborated by science since the seventeenth century, is radically incomplete. The materialist laws of nature must, he says, be supplemented by something else if we are to fold ourselves and our minds fully into our science.

There's a name for that set of beliefs: creationism.
