Silence is as full of potential wisdom and wit as the unshown marble of great sculpture. The silent bear no witness against themselves.

Books have their destinies like men. And their fates, as made by generations of readers, are very different from the destinies foreseen for them by their authors. Gulliver's Travels, with a minimum of expurgation, has become a children's book; a new illustrated edition is produced every Christmas. That's what comes of saying profound things about humanity in terms of a fairy story.

The man who has successfully solved the problem of his relations with the two worlds of data and symbols is a man who has no beliefs. With regard to the problems of practical life he entertains a series of working hypotheses, which serve his purposes, but are taken no more seriously than any other kind of tool or instrument. In other words, symbols should never be raised to the rank of dogmas, nor should any system be regarded as more than a provisional convenience.

The effects which follow too constant and intense a concentration upon evil are always disastrous. Those who crusade, not for God in themselves, but against the devil in others, never succeed in making the world better, but leave it either as it was, or sometimes even perceptibly worse than it was, before the crusade began. By thinking primarily of evil we tend, however excellent our intentions, to create occasions for evil to manifest itself.

Man is unique in organizing the mass murder of his own species.
