The scientific value of truth is not, however, ultimate or absolute. It rests partly on practical, partly on aesthetic interests.

A man's feet should be planted in his country, but his eyes should survey the world.

Memory itself is an internal rumour; and when to this hearsay within the mind we add the falsified echoes that reach us from others, we have but a shifting and unseizable basis to build upon.

Parents lend children their experience and a vicarious memory; children endow their parents with a vicarious immortality.

Sanity is madness put to good use.
