You know, when you get to the New World and you develop your three branches of government and you have a civil society, you can just jettison all the barbarism I recommended in the first books.

A kernel of truth lurks at the heart of religion, because spiritual experience, ethical behavior, and strong communities are essential for human happiness. And yet our religious traditions are intellectually defunct and politically ruinous. While spiritual experience is clearly a natural propensity of the human mind, we need not believe anything on insufficient evidence to actualize it.

If history reveals any categorical truth, it is that an insufficient taste for evidence regularly brings out the worst in us. Add weapons of mass destruction to this diabolical clockwork, and you have . . . a recipe for the fall of civilization.

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.

The fact that one can lose one's sense of self in an ocean of tranquility does not mean that one's consciousness is immaterial or that it presided over the birth of the universe.

Liberals tend to understand that a person can be lucky or unlucky in all matters relevant to his success. Conservatives, however, often make a religious fetish of individualism. Many seem to have absolutely no awareness of how fortunate one must be to succeed at anything in life, no matter how hard one works. One must be lucky to be able to work. One must be lucky to be intelligent, physically healthy, and not bankrupted in middle age by the illness of a spouse.
