“Faith, sir, as to that matter, I don't believe one half of it myself.”

“...evolution is not a religious tenet, to which one swears allegiance or belief as a matter of faith.. It is a factual reality of the empirical world. Just as one would not say 'I believe in gravity," one should not proclaim 'I believe in evolution.”

“I don't believe for a minute that the proof of God's existence is achieved. My faith prohibits me from believing that the proof of God's existence can ever be adduced. My God is not an object for verification, He is a subject for love. My faith is not knowledge, it is acceptance. It is a matter not of calculation but of trust.”

“Faith is a great thing, and really religious people would like us to believe that faith and knowing are the same thing, but I don't believe that myself. Because there are too many different ideas on the subject. What we know is this: When we die, one of two things happens. Either our souls and thoughts somehow survive the experience of dying or they don't. If they do, that opens up every possibility you could think of. If they don't, it's just blotto. The end.”

“I don't blame any one for not believing my history. If I had not experienced what I have, I could not have believed it myself.”

“It's lack of faith that makes people afraid of meeting challenges, and I believed in myself.”
