"There is something patently insane about all the typewriters sleeping with all the beautiful plumbing in the beautiful office buildings —and all the people sleeping in the slums."
"I set about fifty-five years ago (1927) to see what a penniless, unknown human individual with a dependent wife and newborn child might be able to do effectively on behalf of all humanity…"
"I do not look upon human beings as good or bad. I don't think of my feet as a right foot and a wrong foot."
"The physical is inherently entropic, giving off energy in ever more disorderly ways. The metaphysical is antientropic, methodically marshalling energy. Life is antientropic. It is spontaneously inquisitive. It sorts out and endeavors to understand."
"Every time man makes a new experiment he always learns more. He cannot learn less."
"Dare to be naïve."
"People should think things out fresh and not just accept conventional terms and the conventional way of doing things."
"I am convinced all of humanity is born with more gifts than we know. Most are born geniuses and just get de-geniused rapidly."

"Children are born true scientists. They spontaneously experiment and experience and reexperience again. They select, combine, and test, seeking to find order in their experiences - "which is the mostest? which is the leastest?" They smell, taste, bite, and touch-test for hardness, softness, springiness, roughness, smoothness, coldness, warmness: the heft, shake, punch, squeeze, push, crush, rub, and try to pull things apart."
"I think I am a verb."
"We have a habit in writing articles published in scientific journals to make the work as finished as possible, to cover up all the tracks, to not worry about the blind alleys or describe how you had the wrong idea at first, and so on. So there isn't any place to publish, in a dignified manner, what you actually did in order to get to do the work."
