The monopoly of science in the realm of knowledge explains why evolutionary biologists do not find it meaningful to address the question whether the Darwinian theory is true.

If modernist naturalism were true, there would be no objective truth outside of science. In that case right and wrong would be a matter of cultural preference, or political power, and the power already available to modernists ideologies would be overwhelming.

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.

Some theists in evolutionary science acquiesce to these tacit rules and retain a personal faith while accepting a thoroughly naturalistic picture of physical reality.

All the most prominent Darwinists proclaim naturalistic philosophy when they think it safe to do so.

In short, the proposition that God was in any way involved in our creation is effectively outlawed, and implicitly negated.

The second advantage claimed for naturalism is that it is equivalent to rationality, because it assumes a model of reality in which all events are in principle accessible to scientific investigation.
