>Almost a century ago, when Freud had just published his groundbreaking Three Essays on Sexuality, the Viennese writer Otto Soyka published a fiery little volume called Beyond the Boundary of Morals. Never widely known, and now entirely forgotten, it was a polemic directed against the prohibition of "unnatural" sex like bestiality, homosexuality, fetishism and other non-reproductive acts. Soyka saw these prohibitions as futile and misguided attempts to limit the inexhaustible variety of human sexual desire. Only bestiality, he argued, should be illegal, and even then, only in so far as it shows cruelty towards an animal.

why does it feel more comfortable endorsing a position with some kind of precedent? appeal to authority?
