Such instances of the almost infinite unpredictability of man are known to social scientists, but they are no more affected by them than the asylum inmate is by being told that he is not Napoleon.

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.

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

Physical scientists probably deserve the reputation they enjoy for incorruptibility and unswerving devotion to pure truth. The reason for this is that it is not worth while to bribe them.

The dreadful cocksureness that is characteristic of scientists in bulk is not only quite foreign to the spirit of true science, it is not even justified by a superficial view.

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.

Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.
