I cannot escape from the conclusion that the great ages of progress have depended upon a small number of individuals of transcendent ability.

In the first place a philosophical proposition must be general. It must not deal specially with things on the surface of the earth, or within the solar system, or with any other portion of space and time. . . . This brings us to a second characteristic of philosophical propositions, namely that they must be a priori. A philosophical proposition must be such as can neither be proved nor disproved by empirical evidence. . . . Philosophy, if what has been said is correct, becomes indistinguishable from logic as that word has now come to be used.

The moral thing I should wish to say to them is very simple; I should say: "Love is wise - Hatred is foolish." In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other.

No; we have been as usual asking the wrong question. It does not matter a hoot what the mockingbird on the chimney is singing. The real and proper question is: Why is it beautiful?

Moral progress has consisted in the main of protest against cruel customs, and of attempts to enlarge human sympathy.

I hold all knowledge that is concerned with things that actually exist - all that is commonly called Science - to be of very slight value compared to the knowledge which, like philosophy and mathematics, is concerned with ideal and eternal objects, and is freed from this miserable world which God has made.

Indemnity for the past and security for the future.
