Scientists do not join hands every Sunday and sing "Yes gravity is real! I know gravity is real! I will have faith! I believe in my heart that what goes up, up, up must come down, down, down. Amen!" If they did, we would think they were pretty insecure about the concept.

The very concept of sin comes from the Bible. Christianity offers to solve a problem of its own making! Would you be thankful to a person who cut you with a knife in order to sell you a bandage?

There is no evidence for a god, no coherent definition of a god, no good argument for a god, good positive arguments against a god, no agreement among believers about the nature or moral principles of a god, and no need for a god. We can live happy, moral, productive lives without such belief, and we can do it better.

It is wrong for a secular government to promote prayer. We think the National Day of Prayer is unconstitutional. What if the president declared a National Day of Cursing God because He failed us on September 11? Americans would say, "You've overstepped your authority." That's how we feel when he promotes prayer.

Even if it is true that all cultures share a common morality, why does this prove a supreme intelligence? After all, don't we humanists sometimes claim that there is a common thread of humanistic values running through history across cultural and religious lines?

There is joy in rationality, happiness in clarity of mind. Freethought is thrilling and fulfilling - absolutely essential to mental health and happiness.

Only sinners need saviors.
