“The object of the new school is to teach reasonable doubt. Not the unreasonable doubt of the wild-eyed heckler, but the evidence-based doubt of the questioning scientist and the reason-based doubt of the skilled debater.”

“No doubt about it, Lawrence Decker was the reason God had invented nakedness.”

“The mind God is looking for in man is a doubting, questioning mind, not a dogmatic mind; dogmatic reasoning is wrong reasoning. Dogmatic reason ties a huge rock to a man’s foot and stops him forever from advancing.”

“There is no proof great enough to prevent doubt. Ir you base your belief on proof, sooner or later you will sink!”

“What should we think of someone who never admits error, never entertains doubt but adheres unflinchingly to the same ideas all his life, regardless of new evidence?

It is doubt that shows we are still thinking, still willing to reexamine hardened beliefs when confronted with new facts and new evidence.”

“I ought not to doubt the steadiness of your affection, yet such is the inconsistency of real love, that it is always awake to suspicion, however unreasonable; always requiring new assurances from the object of its interest, and thus it is, that I always feel revived, as by a new conviction, when your words tell me I am dear to you; and, wanting these, I relapse into doubt, and too often into despondency.”
