Religious faith obscures uncertainty where uncertainty . . . exists, allowing the unknown, the implausible, and the . . . false to achieve primacy over the facts.

Theology is now little more than a branch of human ignorance.

What we do in every other area of our lives (other than religion), is, rather than respect somebody's beliefs, we evaluate their reasons.

Where we have reasons for what we believe, we have no need of faith; where we have no reasons, we have lost both our connection to the world and to one another.

Man is manifestly not the measure of all things. This universe is shot through with mystery. The very fact of its being, and of our own, is a mystery absolute, and the only miracle worthy of the name.

The fact that my continuous and public rejection of Christianity does not worry me in the least should suggest to you just how inadequate I think your reasons for being a Christian are.

An argument can be logically valid, but unsound in that it contains a false premise and, therefore, leads to a false conclusion (e.g., Scientists are smart; smart people do not make mistakes; therefore, scientists do not make mistakes).
