“Creationist? Well, no, it’s not creationist either. The point is that we are probably a bit less top-to-bottom thorough than, say, the Army Corps of Engineers. Well, actually, scratch that. We are probably about exactly as thorough as the Army Corps of Engineers, in that we are intermittently thorough.”

“Few things hold the perception more thoroughly captive than anxiety about what we have got to say”

“I think if we ever reach the point where we think we thoroughly understand who we are and where we came from, we will have failed.”

“We have convictions only if we have studied nothing thoroughly.”

“We all take such pains to over-educate ourselves. In the wild struggle for existence, we want to have something that endures, and so we fill our minds with rubbish and facts, in the silly hope of keeping our place. The thoroughly well-informed man - that is the modern ideal. And the mind of the thoroughly well-informed man is a dreadful thing. It is like a bric-a-brac shop, all monsters and dust, with everything priced above its proper value.”

“No mind is thoroughly well-organized that is deficient in a sense of humor.”
