“Revolutionary man must be a contingent being, unjustifiable but free, entirely immersed in the society that oppresses him, but capable of transcending this society by his effort to change it. Idealism mystifies him in that it binds him by rights and values that are already given; it conceals from him his power to devise roads of his own. But materialism also mystifies him, by depriving him of his freedom. The revolutionary philosophy must be a philosophy of transcendence.”
