In the actual duration of his life, the individual ranges from the bacterium's hour to the the big tree's five thousand years.By speech first, but far more by writing, man has been able to put something of himself beyond death. In tradition and in books an integral part of the individual persists, for it can influence the minds and actions of other people in different places and at different times: a row of black marks on a page can move a man to tears, though the bones of him that wrote it are long ago crumbled to dust.
Julian Huxley
