Philosopher David Chalmers notes that there has been a shift among philosophers of mind in the last decade from a strict materialistic reductionism (or physicalism) toward the view that mind cannot be reduced to matter (dualism), that mind and matter are essentially disparate entities. Dualists, by Chalmers' estimation, are still in the minority, but their numbers are growing. This is a fascinating development after a century and a half of philosophers and neurobiologists trying to show that mind is nothing more than a word we use to describe the function of the brain.
Materialism seems to be under assault everywhere. Marxist economic materialism has long been discredited, of course, and within the last fifteen years materialist conceptions of the cosmos have become increasingly untenable in light of discoveries being made by cosmologists about the fine-tuning of the fundamental forces, laws, and constants which govern the universe. Similarly, Intelligent Design is challenging materialism in the realm of biology, and now many philosophers are concluding that consciousness is something other than just chemical reactions in the brain.
Next thing you know philosophers will be resurrecting the concept of soul. It reminds me of the closing words of Robert Jastrow's God and the Astronomers. Jastrow notes that scientists have struggled, like men climbing a mountain, for every foothold and handhold that would help them reach the pinnacle - an understanding how our universe works. Every scrap of knowledge came at a great cost in effort and labor. Finally, after centuries of working their way toward the summit, they heave themselves over the last ledge only to find a bunch of theologians who've been sitting at the top all along.
