Note 242 — Chapter VI · —THE THEORY OF SEXUAL INVERSION.

Alcohol has sometimes been considered an important exciting cause of homosexuality, and alcoholism is certainly not uncommon in the heredity of inverts; according to Hirschfeld (Die Homosexualität, p. 386) it is well marked in one of the parents in over 21 per cent, of cases. But it probably has no more influence as an exciting cause in the individual homosexual person than in the individual heterosexual person. From the Freudian standpoint, indeed, Abraham believes (Zeitschrift für Sexualwissenschaft, Heft 8, 1908) that even in normal persons alcohol removes the inhibition from a latent homosexuality, and Juliusburger from the same standpoint (Zentralblatt für Psychoanalyse, Heft 10 and 11, 1912) thinks that the alcoholic tendency is unconsciously aroused by the homosexual impulse in order to reach its own gratification. But we may accept Näcke's conclusions (Allgemeine Zeitschrift für Psychiatrie, vol. lxviii, 1911, p. 852), that (1) alcohol cannot produce homosexuality in persons not predisposed, that (2) it may arouse it in those who are predisposed, that (3) the action of alcohol is the same on the homosexual as the heterosexual, and that (4) alcoholism is not common among inverts.
