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.

But regular biology, as an "ology," has to be "scientific," and this means in practice that it has to be made dull.... Everything has to be expressed in utterly impersonal terms.

Psychologists, like other scientists, pride themselves on being extremely modern, and therefore much better than any group of people that ever were before.

Insight is not the same as scientific deduction, but even at that it may be more reliable than statistics.

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

It is true that physics gives a wonderful training in precise, logical thinking-about physics. It really does depend upon accurate reproducible experiments, and upon framing hypotheses with the greatest possible freedom from dogmatic prejudice. And if these were the really important things in life, physics would be an essential study for everybody.

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.
