Most publicized of this century’s contributions are undoubtedly the monumental statistical studies of sex behavior by the biologist A. C. Kinsey, which have shown homosexual experience to be more prevalent than hitherto claimed even by Ellis or Hirschfeld. Insofar as Kinsey attacks causes, he is with the Freudians in holding that all individuals are potentially bisexual, but there the agreement ceases. Kinsey’s contention is that the human sex drive will find outlet according to its strength in a given individual, and that its satisfaction via the same sex is due to the sensitivity of erogenous zones to any adequate stimuli. This explains satisfactorily the behavior of bisexuals and of homosexuals whose opportunities are largely confined to their own sex, but to account for those who are frigid to the other sex Kinsey is obliged to admit the importance of subjective factors. This brief survey indicates how much the social attitude toward variance has relaxed since the days of Belot and Peladan. Today the sternest counsellors of youth—outside perhaps a few religious groups—no longer talk of homosexuality in terms of depravity and corruption. And the psychiatrist’s charge of arrested development weighs comparatively lightly upon such variants as are fairly well adjusted to their condition. * * * * * Factors other than the scientific have also affected this century’s output of literature dealing with variant women. Until the beginning of World War I, the Woman’s Movement figured sporadically in fiction, but not in variant novels after 1900. As a force in practical politics, however,—sometimes, as in England, a very noisy one—it had by the end of the war won the suffrage battle throughout much of the western world. Even where this end was not achieved, the movement widened women’s educational and occupational opportunities, and thus tended to multiply the total number of feminine authors. Next, the war opened a number of men’s jobs to women, increased their financial and personal independence, and encouraged tendencies toward masculine simplicity in dress. It also brought about that relaxation of sexual standards in general for which the 1920s have become notorious. Taken together, these alterations in women’s status are held by some social historians to have increased female variance. Certainly what may be called a first peak in variant literature was reached between 1925 and 1935. Thus, it is not surprising to discover that during the first third of the present century, literary titles dealing with variant women averaged more than one per year, that at least half were written by women, and that a majority were more favorable to variance than otherwise.
