I am become death, the destroyer of worlds....

The optimist thinks this is the best of all possible worlds. The pessimist fears it is true.

The atomic bomb made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass and beyond there is a different country.

In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin and this is a knowledge which they cannot lose.

A man does not die of love or his liver or even of old age he dies of being a man.

Old age is a tyrant, who forbids, under pain of death, the pleasures of youth.

Love has no age, no limit and no death.

It is old age, rather than death, that is to be contrasted with life. Old age is life's parody, whereas death transforms life into a destiny: in a way it preserves it by giving it the absolute dimension. Death does away with time.
