Religious faith is the one species of human ignorance that will not admit of even the possibility of correction.

Some ... sexist evil probably predates religion and can be ascribed to our biology, but there is no question that religion promulgates and renders sacrosanct attitudes toward women that would be unseemly in a brachiating ape.

It is time we recognized that belief is not a private matter; it has never been merely private. In fact, beliefs are scarcely more private than actions are, for every belief is a fount of action in potential.

Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts.

Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe.

The problem is that religion tends to give people bad reasons to be good.

As many critics of religion have pointed out, the notion of a creator poses an immediate problem of an infinite regress. If God created the universe, what created God? To say that God, by definition, is uncreated simply begs the question. Any being capable of creating a complex world promises to be very complex himself. As the biologist Richard Dawkins has observed repeatedly, the only natural process we know of that could produce a being capable of designing things is evolution.
