The mark of a civilized man is his willingness to re-examine his most cherished beliefs.

We should be eternally vigilant against attempts to check the expression of opinions that we loathe.

People talk fundamentals and superlatives and then make some changes of detail.

To be civilized is to be potentially master of all possible ideas, and that means that one has got beyond being shocked, although one preserves one's own moral aesthetic preferences.

There is in all men a demand for the superlative, so much so that the poor devil that has no other way of reaching it attains it by getting drunk.

I know of no teachers so powerful and persuasive as the little army of specialists. They carry no banners, they beat no drums; but where they are men learn that bustle and push are not the equals of quiet genius and serene mastery.

Our test of truth is a reference to either a present or imagined future majority in favour of our view.
