“ Let any man consult his own experience; he knows how consciousness is clogged, so to speak, by sexual desire; it seems that one is invaded by facticity, that one ceases to flee it and that one slides toward a passive consent to the desire. At other moments it seems that facticity invades consciousness in its very flight and renders consciousness opaque to itself. ”
