According to the scientific naturalist version of cosmic history, nature is a permanently closed system of material effects that can never be influenced by something from outside - like God, for example.

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.

First, Darwinian theory tells us how a certain amount of diversity in life forms can develop once we have various types of complex living organisms already in existence.

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.

Darwinism is not merely a support for naturalistic philosophy: it is a product of naturalistic philosophy.

A constitutional democracy is in serious trouble if its citizenry does not have a certain degree of education and civic virtue.
