“You don't invent circumstances, but when they happen they reveal human nature.”

“There are moments when we think nature happens just for us, and there are other moments when the ridiculousness of that notion is revealed.”

“Circumstances don't make the man, they only reveal him to himself.”

“When freedom prevails, the ingenuity and inventiveness of people creates incredible wealth. This is the source of the natural improvement of the human condition.”

“We mustn't be afraid of inventing anything...Everething there is in us exists in nature. After all, we're part of nature. If it resembles nature, that's fine. If it doesn't, what of it? When man wanted to invent something as useful as the human foot, he invented the wheel, which he used to transport himself and his burdens. The fact that the wheel doesn't have the slightest resemblance to the human foot is hardly a criticism of it.”

“Human attention, in the best of circumstances, is a fluid but fragile entity. Beyond a certain threshold, the more that is asked of it, the less well it performs. When this happens in a psychological experiment, it is interesting. When it happens in traffic, it can be fatal.”
