As an advocate of birth control I wish ... to point out that the unbalance between the birth rate of the 'unfit' and the 'fit,' admittedly the greatest present menace to civilization, can never be rectified by the inauguration of a cradle competition between these two classes. In this matter, the example of the inferior classes, the fertility of the feeble-minded, the mentally defective, the poverty-stricken classes, should not be held up for emulation.... On the contrary, the most urgent problem today is how to limit and discourage the over-fertility of the mentally and physically defective.

Eugenics is ... the most adequate and thorough avenue to the solution of racial, political and social problems.

Women must have economic and social equality with men.

... it has always been the depth of my belief, my faith, or my love that was the mainspring of my behavior. When once I believed in doing a thing, nothing could prevent my doing it.

The greatest issue is to raise the question of birth control out of the gutter of obscenity ... into the light of intelligence and human understanding.

The undeniably feeble-minded should, indeed, not only be discouraged but prevented from propagating their kind.

Birth control is nothing more or less than...weeding out the unfit.
