For pornography is not directly obscene: it excites only as long as there is a struggle within the viewer between lust and the angel of culture. When the devils carry off the angel; when, as a result of general tolerance, the weakness of sexual prohibitions—their complete helplessness—is laid bare; when prohibitions are thrown on the rubbish heap, then how quickly pornography betrays its innocent (which here means ineffective) character, for it is a false promise of carnal bliss, an augury of something which does not in fact come true. It is the forbidden fruit, so there is as much temptation in it as there is power in the prohibition.
