No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water.
When she was fifteen if you'd told her that when she was twenty she'd be going to bed with bald-headed men and liking it, she would have thought you very abstract.
By the toll of a billion deaths man has bought his birthright of the earth, and it is his against all comers; it would still be his were the Martians ten times as mighty as they are. For neither do men live nor die in vain.
The ethical system of these men of the New Republic, the ethical system which will dominate the world state, will be shaped primarily to favour the procreation of what is fine and efficient and beautiful in humanity — beautiful and strong bodies, clear and powerful minds, and a growing body of knowledge — and to check the procreation of base and servile types, of fear-driven and cowardly souls, of all that is mean and ugly and bestial in the souls, bodies, or habits of men.

War is a curtain of dense black fabric across all the hopes and kindliness of mankind. Yet always it has let through some gleams of light, and not--I am not dreaming--it grows threadbare, and here and there and at a thousand points the light is breaking through.
We are living in 1937, and our universities, I suggest, are not half-way out of the fifteenth century. We have made hardly any changes in our conception of university organization, education, graduation, for a century - for several centuries.
The professional military mind is by necessity an inferior and unimaginative mind; no man of high intellectual quality would willingly imprison his gifts in such a calling.
You have, let us say, a promising politician, a rising artist that you wish to destroy. Dagger or bomb are archaic, clumsy and unreliable - but teach him, inoculate him with chess.
Alexander the Great changed a few boundaries and killed a few men. Both he and Napoleon were forced into fame by circumstances outside of themselves and by currents of the time, but Margaret Sanger made currents and circumstances. When the history of our civilization is written, it will be a biological history and Margaret Sanger will be its heroine.
