the opinion that the Urning is a Dioning arrested at a certain point of development; but rather that there is an element of uncertainty attending the simultaneous evolution of physical and psychical factors from the indeterminate ground-stuff. "Sex," says he, "is only an affair of development. Up to a certain stage of embryonic existence all living mammals are hermaphroditic. A certain number of them advance to the condition of what I call man (Doining), others to what I call woman (Dioningin), a third class become what I call Urning (including Urningin). It ensues therefrom that between these three sexes there are no primary, but only secondary differences. And yet true differences, constituting sexual species, exist as facts."[1] Man, Woman, and Urning—the third being either a male or a female in whom we observe a real and inborn, not an acquired or a spurious, inversion of appetite—are consequently regarded by him as the three main divisions of humanity viewed from the point of view of sex. The embryonic ground-stuff in the case of each was homologous; but while the two former, Man and Woman, have been normally differentiated, the Urning's sexual instinct, owing to some imperfection in the process of development, does not correspond to his or her sexual organs.
The line of division between the sexes, even in adult life, is a subtle one; and the physical structure of men and women yields indubitable signs of their emergence from a common ground-stuff. Perfect men have rudimentary
breasts. Perfect women carry a rudimentary
