Like Prince von Bismarck in diplomacy, I have no secrets.

The mind is like the stomach. It is not how much you put into it that counts, but how much it digests.

Someone asked me years ago if it were true that I disliked Jews, and I replied that it was certainly true, not at all because they are Jews but because they are folks, and I don't like folks.

Learning has always been made much of, but forgetting has always been deprecated; therefore pedantry has pretty well established itself throughout the modern world at the expense of culture.

Perhaps the prevalence of pedantry may be largely accounted for by the common error of thinking that, because useful knowledge should be remembered, any kind of knowledge that is at all worth learning should be remembered too.

The position of modern science, as far as an ignorant man of letters can understand it, seems not a step in advance of that held by Huxley and Romanes in the last century.
