“That which can be asserted without evidence, can be dismissed without evidence.”

"Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence."

“After Darwin, God's role changes from being the designer of all creatures, great and small, to being the designer of the laws of nature, from which natural selection can unfold, to being just perhaps the chooser of the laws.”

"All that's necessary for the forces of evil to win in the world is for enough good men to do nothing."

"Every great and deep difficulty bears in itself its own solution. It forces us to change our thinking in order to find it."

"I can live with doubt, and uncertainty, and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of certainty about different things, but I'm not absolutely sure of anything, and in many things I don't know anything about. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn't frighten me."
