"The frequency with which a man experiences lust depends upon his own physical condition, whereas the occasions which rouse such feelings in him depend upon the social conventions to which he is accustomed. To an early Victorian man a woman's ankles were sufficient stimulus, whereas a modern man remains unmoved by anything up to the thigh. This is merely a question of fashion in clothing. If nakedness were the fashion, it would cease to excite us, and women would be forced, as they are in certain savage tribes, to adopt clothing as a means of making themselves sexually attractive. Exactly similar considerations apply to literature and pictures; what was exciting in the Victorian age would leave the men of a franker epoch quite unmoved. The more prudes restrict the permissible degree of sexual appeal, the less is required to make such an appeal effective. Nine-tenths of the appeal of pornography is due to the indecent feelings concerning sex which moralists inculcate in the young; the other tenth is physiological, and will occur in one way or another whatever the state of the law may be. On these grounds, although I fear that few will agree with me, I am firmly persuaded that there ought to be no law whatsoever on the subject of obscene publications."
