There's truths you have to grow into.

A world revolution to a higher social order, a world order, or utter downfall lies before us all.

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.

The great body of physical science, a great deal of the essential fact of financial science, and endless social and political problems are only accessible and only thinkable to those who have had a sound training in mathematical analysis, and the time may not be very remote when it will be understood that for complete initiation as an efficient citizen of one of the new great complex worldwide States that are now developing, it is as necessary to be able to compute, to think in averages and maxima and minima, as it is now to be able to read and write.

Very simple was my explanation, and plausible enough---as most wrong theories are!

It sounds plausible enough tonight, but wait until tomorrow. Wait for the common sense of the morning.

Armament should be an illegality everywhere, and some sort of international force should patrol a treaty-bound world. Partial armament is one of those absurdities dear to moderate-minded 'reasonable' men. Armament itself is making war. Making a gun, pointing a gun, and firing it are all acts of the same order. It should be illegal to construct anywhere upon earth any mechanism for the specific purpose of killing men. When you see a gun it is reasonable to ask: 'Whom is that intended to kill?'
