Yes, many naturalists deny that objective moral values exist — that our moral impulse is nothing more than the product of a blind evolutionary process that selects out traits that enhance survival and reproduction. I such a case, morality is merely subjective. However, non-theists can and do endorse objective moral values — that rape or child abuse is wrong. These nontheistic moral realists will tell us, "You don't need God to be good." Yet the deeper question is, how did we come to be morally responsible, rights-bearing beings? Since all human beings are God's image-bearers, they not surprisingly recognize the same sorts of moral values theist do. The basic issue, tough, is this: why think humans have rights and dignity if they're products of valueless, physical processes in a cause-and-effect series from the bing bang until now? The more plausible context or scenario is that human value and moral responsibility come from a good God who created us as intrinsically valuable, morally responsible creatures.

The religious hypothesis of mind-body dualism has been in trouble with evolutionary biology, and with several other sciences as well, for more than a century. It didn't need any special input from artificial intelligence or neuroscience to make it scientifically implausible. I bring it up here only because it is a clear example of a popular and important belief currently under siege by modern information. And because its example may be repeated. The fact is, there is a much more intriguing area of current conceptual commitment, one more likely to be affected by emerging cognitive theory in particular. It lies even closer to home and is even more widespread, if that is possible, than mind-body dualism. It is our current self-conception: our shared portrait of ourselves as self-conscious creatures with beliefs, desires, emotions, and the power of reason.

Your brain is far too complex and mercurial for its behavior to be predicted in any but the broadest outlines or for any but the shortest distances in the future. Faced with the extraordinary dynamical features of a functioning brain, no device constructible in this universe could ever predict your behavior, or your thoughts, with anything more than merely statistical success. ¶ So one need not fear being reduced to a clanking robot or an empty machine. Quite to the contrary, we are now in a position to explain how our vivid sensory experience arises in the sensory cortex of our brains: how the smell of baking bread, the sound of an oboe, the taste of a peach, and the color of a sunrise are embodied in a vast chorus of neural activity. We now have the resources to explain how the motor cortex, the cerebellum, and the spinal cord conduct an orchestra of muscles to perform the cheetah's dash, the falcon's strike, or the ballerina's dying swan. ... On this matter of conceptual development there is especial cause for wonder. For the human brain, with a volume of roughly a quart, encompasses a space of conceptual and cognitive possibilities that is larger, by one measure at least, than the entire astronomical universe. It has this striking feature because it exploits the combinatorics of its 100 billion neurons and their 100 trillion synaptic connections with each other.

We are children of chaos, and the deep structure of change is decay. At root, there is only corruption, and the unstemmable tide of chaos. Gone is purpose; all that is left is direction. This is the bleakness we have to accept as we peer deeply and dispassionately into the heart of the Universe.

Darwinists took the wrong view of science because they were infected with the craving to be right. Their scientific colleagues have allowed them to get away with pseudoscientific practices primarily because most scientists do not understand that there is a difference between the scientific method of inquiry, as articulated by Popper, and the philosophical program of scientific naturalism. One reason that they are not inclined to recognize the difference is that they fear the growth of religious fanaticism if the power of naturalistic philosophy is weakened. But whenever science is enlisted in some other cause — religious, political, or racialistic — the result is always that the scientists themselves become fanatics. Scientists see this clearly when they think about the mistakes of their predecessors, but they find it hard to believe that their colleagues could be making the same mistakes today.

[T]he logic of materialist reductionism implies that science itself is the product of unreasoning material causes. No wonder the Age of Reason ends with the age of postmodernist relativism! And yet we still see the reductionists complacently describing religious belief either as a meme or as the product of a "God module" in the brain without realizing that they are sawing off the limb on which they themselves are sitting. If unthinking matter causes the thoughts the materialists don't like, then what causes the thoughts they do like?

By any realistic definition naturalism is a religion, and an extremely dogmatic one. It rests on a basic conviction about ultimate reality that is held by a kind of faith, and it incorporates its own definitions of "knowledge" and "reason." It says that knowledge comes ultimately from our senses and that the more complex forms of knowledge come from scientific investigation. By naturalistic definition there can be no such thing as knowledge of the supernatural. Statements about God are either nonrational (if frankly presented as mere subjective belief) or irrational (if they purport to make objective factual claims).
