Evolutionary naturalism takes the inherent limitations of science and turns them into a devastating philosophical weapon: because science is our only real way of knowing anything, what science cannot know cannot be real.

A Chinese paleontologist lectures around the world saying that recent fossil finds in his country are inconsistent with the Darwinian theory of evolution. His reason: The major animal groups appear abruptly in the rocks over a relatively short time, rather than evolving gradually from a common ancestor as Darwin's theory predicts. When this conclusion upsets American scientists, he wryly comments: "In China we can criticize Darwin but not the government. In America you can criticize the government but not Darwin."

To philosophical materialists God is no more than an idea in the human mind, and not a very important idea.

Evolutionary naturalism takes the inherent limitations of science and turns them into a devastating philosophical weapon: because science is our only real way of knowing anything, what science cannot know cannot be real.

Materialism sets us free from sin-by proving that there is no such thing as sin. There's just antisocial behavior, which we can control with measures like laws and educational programs.

The assumption that nature is all there is, and that nature has been governed by the same rules at all times and places, makes it possible for natural science to be confident that it can explain such things as how life began.

Truth as such is not a particularly important concept in naturalistic philosophy.
