There is no history: There is only Biography. The attempt to perpetuate, to fix a thought or principle, fails continually. You can only live for yourself: Your action is good only whilst it is alive -- whilst it is in you. The awkward imitation of it by your child or your disciple, in not a repetition of it, is not the same thing but another thing. The new individual must work out the whole problem of science, letters, & theology for himself, can owe his fathers nothing. There is no history: only biography.
