“Everywhere sex is understood to be something females have that males want.”

“One of the most pusillanimous things we of the female sex have done throughout the centuries is to have allowed the male sex to assume that mankind is masculine. It is not. It takes both male and female to make the image of God. The proper understanding of mankind is that it is only a poor, broken thing if either male or female is excluded.”

“It would be ridiculous to talk of male and female atmospheres, male and female springs or rains, male and female sunshine.... how much more ridiculous is it in relation to mind, to soul, to thought, where there is as undeniably no such thing as sex, to talk of male and female education and of male and female schools. [written with Elizabeth Cady Stanton]”

“(In actuality there are no such things as "male" or "female" hormones. Hormones have no sex of their own, and all types of sex hormones are present in all human beings in varying amounts.)”

“How deep congenital sex-inversion roots may be gathered from the fact that the pleasure-dream of the male Urning has to do with male persons, and of the female with females.”

“...There are as many sexes as there are individuals...the seeming neat correspondence between male and female organs is not the end, but the beginning, of sexuality.”
