"Indecency is not wild and lawless. The danger of indecency is exactly that it is tame, dull, direct, inevitable; a mere law in the members."

A sophistry may affect the mind, but an obscenity must affect the mind; it is a violence. It may do one of two things equally direct and instinctive; it may shock purity or it may inflame impurity. But in both cases the process is brutal and irrational. A picture or a sentence which shocks sensibility or sharpens sensuality does not offer itself for discussion. It is no more open to argument than a squeaking slate pencil is open to argument, or the choking smell of ether is open to argument. The human victim is drugged — or he is sick.

Therefore (without carrying the parallel, of course, to any lengths of literalism), I think we may speak of indecorum as an assault. In the matter of violations of traditional public decency (however plausibly defended) I am entirely with the Puritans. The ordinary argument that sex can be treated calmly and freely like anything else is the most loathsome cant in this canting epoch. The parallels from other crimes are insolently fallacious. A man reading about a burglary is not any more likely to commit a burglary. A man who has seen a pocket picked is not in the least likely to become a pickpocket. But there is one evil which, by its hold on the imagination (the creative and reproductive part of man), can reproduce itself even by report. We have a right to protect ourselves and especially our top-heavy and groping children against startling and uncivilized appeals to this instinct. Heretics have a legal claim to persuade human souls to err and sin like human souls; they have no business to make them jump like monkeys on a stick. I have no more right to give an unwilling citizen a sexual shock than to give him an electric shock. I have no more right to come behind him and inflame his passions than to come behind him and inflame his coattails. …

The appeal to animal appetite may succeed by its very familiarity. Indecency is not wild and lawless. The danger of indecency is exactly that it is tame, dull, direct, inevitable; a mere law in the members. It is automatic evil. Pride makes a man a devil; but lust makes him a machine.
