Robert A. Heinlein

Hand the people a scapegoat to hate. Let them kill a scapegoat occasionally for cathartic release. The mechanism is ages old. Tyrants used it centuries before the word "psychology" was ever invented. It works, too.

A rational anarchist believes that concepts, such as "state" and "society" and "government" have no existence save as physically exemplified in the acts of self-responsible individuals. He believes that it is impossible to shift blame, share blame, distribute blame ... as blame, guilt, responsibility are matters taking place inside human beings singly and nowhere else. But being rational, he knows that not all individuals hold his evaluations, so he tries to live perfectly in an imperfect world ... aware that his efforts will be less than perfect yet undismayed by self-knowledge of self-failure.

Jealousy is a disease, love is a healthy condition. The immature mind often confuses one for the other, or assumes the greater the love, the greater the jealousy. In fact they are almost incompatible; both at once produce unbearable turmoil.

Man is not a rational animal, he is a rationalizing animal.

The capacity of the human mind for swallowing nonsense and spewing it forth in violent and repressive action has never yet been plumbed.

Everything is theoretically impossible, until it is done. One could write a history of science in reverse by assembling the solemn pronouncements of highest authority about what could not be done and could never happen.

If you would know a man, observe how he treats a cat.
