- Not Clearly Pro or Con to the question "Is Sexual Orientation Determined at Birth?"
“Several cases of sexual inversion in which the subjects were disposed to form amatory attachments to other men, have been under my observation. They are even more distressing and disgusting than cases such as the details of which I have just given; but it is necessary for the elucidation of the subject to bring their details before the practitioner. So long as human nature exists such instances will occur and physicians must be prepared to treat them.”
Sexual Impotence in the Male and Female, 1887
