People who harbor strong convictions without evidence belong at the margins of our societies, not in our halls of power. The only thing we should respect in a person’s faith is his desire for a better life in this world; we need never have respected his certainty that one awaits him in the next.

You don't get anything worth getting, by pretending to know things you don't know.

In fact, "atheism" is a term that should not even exist. No one ever needs to identify himself as a "non-astrologer" or a "non-alchemist."

Atheism is nothing more than the noises reasonable people make in the presence of unjustified religious beliefs.
