People have been marrying and bringing up children for centuries now. Nothing has ever come of it.

The chief difficulty of modern theoretical physics resides not in the fact that it expresses itself almost exclusively in mathematical symbols, but in the psychological difficulty of supposing that complete nonsense can be seriously promulgated and transmitted by persons who have sufficient intelligence of some kind to perform operations in differential and integral calculus.

That society exists to frustrate the individual may be seen from its attitude to work. It is only morally acceptable if you do not want to do it. If you do want to, it becomes a personal pleasure.

If you stand up to the human race you lose something called their 'goodwill'; if you kowtow to them you gain ... their permission to continue kowtowing.

What appear to be the most valuable aspects of the theoretical physics we have are the mathematical descriptions which enable us to predict events. These equations are, we would argue, the only realities we can be certain of in physics; any other ways we have of thinking about the situation are visual aids or mnemonics which make it easier for beings with our sort of macroscopic experience to use and remember the equations.

It is easier to study the 'behavior' of rats than people, because rats are smaller and have fewer outside commitments. So modern psychology is mostly about rats
