Knowledge keeps no better than fish.

I put forward as a general definition of civilization, that a civilized society is exhibiting the five qualities of Truth, Beauty, Adventure, Art, Peace.

Art flourishes where there is a sense of adventure, a sense of nothing having been done before, of complete freedom to experiment.

The absolute pacifist is a bad citizen; times come when force must be used to uphold right, justice and ideals.

Art flourishes where there is a sense of adventure.

It does not matter what men say in words, so long as their activities are controlled by settled instincts. The words may ultimately destroy the instincts; but until this has occurred, words do not count.

Algebra reverses the relative importance of the factors in ordinary language. It is essentially a written language, and it endeavors to exemplify in its written structures the patterns which it is its purpose to convey. The pattern of the marks on paper is a particular instance of the pattern to be conveyed to thought. The algebraic method is our best approach to the expression of necessity, by reason of its reduction of accident to the ghostlike character of the real variable.
