"This mystification of useless effort is more intolerable than fatigue. Life imprisonment is the most horrible of punishments because it preserves existence in its pure facticity but forbids it all legitimation. A freedom can not will itself without willing itself as an indefinite movement. It must absolutely reject the constraints which arrest its drive toward itself. This rejection takes on a positive aspect when the constraint is natural. One rejects the illness by curing it. But it again assumes the negative aspect of revolt when the oppressor is a human freedom. One can not deny being: the in-itself is, and negation has no hold over this being, this pure positivity; one does not escape this fullness: a destroyed house is a ruin; a broken chain is scrap iron: one attains only signification and, through it, the for-itself which is projected there; the for-itself carries nothingness in its heart and can be annihilated, whether in the very upsurge of its existence or through the world in which it exists. The prison is repudiated as such when the prisoner escapes. But revolt, insofar as it is pure negative movement, remains abstract. It is fulfilled as freedom only by returning to the positive, that is, by giving itself a content through action, escape, political struggle, revolution. Human transcendence then seeks, with the destruction of the given situation, the whole future which will flow from its victory."
