The struggle with the past is not a hand-to-hand fight. The future overcomes it by swallowing it. If it leaves anything outside it is lost.

In this initial illimitableness of possibilities that characterizes one who has no nature there stands out only one fixed, pre-established, and given line by which he may chart his course, only one limit: the past.
