We do not accept a religion because it offers us certain rewards. The only thing that a religion can offer us is to be just what it, in itself, is: a greater meaning in ourselves, in our lives, and in our grasp of the nature of things...a religion exists for us only if, like a piece of poetry, it carries us away.

The information in DNA could no more be reduced to the chemical than could the ideas in a book be reduced to the ink and paper: something beyond physics and chemistry encoded DNA.

No inanimate object is ever fully determined by the laws of physics and chemistry.
