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

I think the greatest sin in the world is bringing children into the world that have disease from their parents, that have no chance to be a human being, practically. Delinquents, prisoners, all sorts of things just marked when they're born. That to me is the greatest sin - that people can - can commit.

War, famine, poverty and oppression of the workers will continue while woman makes life cheap. They will cease only when she limits her reproductivity and human life is no longer a thing to be wasted.

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

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.

Birth control appeals to the advanced radical because it is calculated to undermine the authority of the Christian churches. I look forward to seeing humanity free someday of the tryanny of Christianity no less than Capitalism.

As I look back upon my life, I see that every part of it was a preparation for the next. The most trivial of incidents fits into the larger pattern like a mosaic in a preconceived design.
