Chemists are, on the whole, like physicists, only 'less so'.They don't make quite the same wonderful mistakes, and much what they do is an art, related to cooking, instead of a true science. They have their moments, and their sources of legitimate pride. They don't split atoms, as the physicists do. They join them together, and a very praiseworthy activity that is.

[Scientists] define these [terms] in tight phrases which convey a meaning only to those who already understand it.

There's many a true word spoken in jest; scientists are abominably solemn; therefore scientists miss many a true word.

Psychologists pay lip service to the scientific method, and use it whenever it is convenient; but when it isn't they make wild leaps of their uncontrolled fancy.

Scientists are convinced that they, as scientists, possess a number of very admirable human qualities, such as accuracy, observation, reasoning power, intellectual curiosity, tolerance, and even humility.

If you want to understand human beings, there are plenty of people to go to besides psychologists.... Most of these people are incapable of communicating their knowledge, but those who can communicate it are novelists. They are good novelists precisely because they are good psychologists.

We are having wool pulled over our eyes if we let ourselves be convinced that scientists, taken as a group, are anything special in the way of brains. They are very ordinary professional men, and all they know is their own trade, just like all other professional men. There are some geniuses among them, just as there are mental giants in any other field of endeavor.
