Otto Weininger,
Sex & Character
(1906)
“ That the rudiment of homo-sexuality, in however weak a form, exists in every human being, corresponding to the greater or smaller development of the characters of the opposite sex, is proved conclusively from the fact that in the adolescent stage, while there is still a considerable amount of undifferentiated sexuality, and before the internal secretions have exerted their stimulating force, passionate attachments with a sensual side are the rule amongst boys as well as amongst girls. ”
