More children from the fit, less from the unfit -- that is the chief aim of birth control.

Through sex, mankind may attain the great spiritual illumination which will transform the world, which will light up the only path to earthly paradise.

No woman can call herself free who cannot choose the time to be a mother or not as she sees fit.

Every single case of inherited defect, every malformed child, every congenitally tainted human being brought into this world is of infinite importance to that poor individual; but it is of scarcely less importance to the rest of us and to all of our children who must pay in one way or another for these biological and racial mistakes.

Many people are horrified at the idea of birth control. . . . It is simply the keynote of a new moral program.

Woman must have her freedom, the fundamental freedom of choosing whether or not she will be a mother and how many children she will have. Regardless of what man's attitude may be, that problem is hers - and before it can be his, it is hers alone.

The most far-reaching social development of modern times is the revolt of woman against sex servitude. The most important force in the remaking of the world is a free motherhood.
