"Oppression divides the world into two clans: those who enlighten mankind by thrusting it ahead of itself and those who are condemned to mark time hopelessly in order merely to support the collectivity; their life is a pure repetition of mechanical gestures; their leisure is just about sufficient for them to regain their strength; the oppressor feeds himself on their transcendence and refuses to extend it by a free recognition. The oppressed has only one solution: to deny the harmony of that mankind from which an attempt is made to exclude him, to prove that he is a man and that he is free by revolting against the tyrants. In order to prevent this revolt, one of the ruses of oppression is to camouflage itself behind a natural situation since, after all, one can not revolt against nature. When a conservative wishes to show that the proletariat is not oppressed, he declares that the present is a natural fact and that there is thus no means of rejecting it; and doubtless he has a good case for proving that, strictly speaking, he is not stealing from the worker "the product of his labor," since the word theft supposes social conventions which in other respects authorizes this type of exploitation; but what the revolutionary means by this word is that the present regime is a human fact. As such, it has to be rejected. This rejection cuts off the will of the oppressor, in his turn, from the future toward which he was hoping to thrust himself alone: another future is substituted, that of revolution. The struggle is not one of words and ideologies; it is real and concrete, if it is this future which triumphs, and not the former, then it is the oppressed who is realized as a positive and open freedom and the oppressor who becomes an obstacle and a thing."
