Theology is ignorance with wings.

The only thing that guarantees an open-ended collaboration among human beings, the only thing that guarantees that this project is truly open-ended, is a willingness to have our beliefs and behaviors modified by the power of conversation.

If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.

We must continually remind ourselves that there is a difference between what is natural and what is actually good for us.

To not believe in God is to know that it falls to us to make the world a better place.

The atheist, by merely being in touch with reality, appears shamefully out of touch with the fantasy life of his neighbors.

When considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't. Religion is one area of our lives where people imagine that some other standard of intellectual integrity applies.
