It is the needs of people, the revolt of a class, which define aims and goals. It is from within a rejected situation, in the light of this rejection, that a new state appears as desirable; only the will of men decides; and it is on the basis of a certain individual act of rooting itself in the historical and economic world that this will thrusts itself toward the future and then chooses a perspective where such words as goal, progress, efficacy, success, failure, action, adversaries, instruments, and obstacles, have a meaning. Then certain acts can be regarded as good and others as bad.
