“Well, I've worried some about, you know, why write books ... why are we teaching people to write books when presidents and senators do not read them, and generals do not read them. And it's been the university experience that taught me that there is a very good reason, that you catch people before they become generals and presidents and so forth and you poison their minds with ... humanity, and however you want to poison their minds, it's presumably to encourage them to make a better world.”
