to be congenital, and Uraniasters, in whom it has been acquired or deliberately adopted. And it would be very difficult to frame laws which should take cognisance of these two classes. The Code Napoleon legalises the position of both, theoretically at any rate. The English code treats both as criminal, doing thereby, it must be admitted, marked injustice to recognised Urnings, who at the worst are morbid or insane, or sexually deformed, through no fault of their own. In the present state of things, adds Ulrichs, the men who yield their bodies to abnormal lovers, do not merely do so out of compliance, sympathy, or the desire for reasonable reward. Too often they speculate upon the illegality of the connection, and have their main object in the extortion of money by threats of exposure. Thus the very basest of all trades, that of _chantage_, is encouraged by the law. Alter the law, and instead of increasing vice, you will diminish it; for a man who should then meet the advances of an Urning, would do so out of compliance, or, as is the case with female prostitutes, upon the expectation of a reasonable gain. The temptation to ply a disgraceful profession with the object of extorting money would be removed. Moreover, as regards individuals alike abnormally constituted, voluntary and mutually satisfying relations, free from degrading risks, and possibly permanent, might be formed between responsible agents. Finally, if it be feared that the removal of legal disabilities would turn the whole male population into Urnings, consider whether London is now so much purer in this respect than Paris? One serious objection to recognising and tolerating sexual inversion has always been that it tends to check the population. This was a sound political and social argument in the time of Moses, when a small and militant tribe needed to multiply to the full extent of its procreative capacity. It is by no means so valid in our age, when the habitable portions of the globe are rapidly becoming overcrowded.[62] Moreover, we must bear in mind that society, under the existing order, sanctions female prostitution, whereby men and women, the normally procreative, are sterilised to an indefinite extent. Logic, in these circumstances, renders it equitable and ridiculous to deny a sterile exercise of sex to abnormal men and women, who are by instinct and congenital diathesis non-procreative.
