“To come to this war: despite the known disposition of the actors in a struggle to overrate its importance, and when it is over to return to their admiration of earlier events, yet an examination of the facts will show that it was much greater than the wars which preceded it.”

“The tragedy of the War is now to be followed by the greater tragedy of peace. The ostensible plea for the War as a struggle for the freedom of small nations now becomes clear as a War of Imperialism. The War for the so-called democratisation of Germany has now turned into a War for the crushing of the rising working class of Europe.”

“It is mere illusion and pretty sentiment to expect much from mankind if he forgets how to make war. And yet no means are known which call so much into action as a great war, that rough energy born of the camp, that deep impersonality born of hatred, that conscience born of murder and cold-bloodedness, that fervor born of effort of the annihilation of the enemy, that proud indifference to loss, to one's own existence, to that of one's fellows, to that earthquake-like soul-shaking that a people needs when it is losing its vitality.”

“Having a spine is overrated. If everybody squealed and ran away, there'd be no more wars.”

“Peace demands the most heroic labor and the most difficult sacrifice. It demands greater heroism than war. It demands greater fidelity to the truth and a much more perfect purity of conscience.”

“The time for war has not yet come, but it will come, and that soon; and when it does come, my advice is to draw the sword and throw away the scabbard.”

“Preventing war is much better than protesting against the war. Protesting the war is too late.”

“Nothing is more impressive than the fact that as mathematics withdrew increasingly into the upper regions of ever greater extremes of abstract thought, it returned back to earth with a corresponding growth of importance for the analysis of concrete fact. …The paradox is now fully established that the utmost abstractions are the true weapons with which to control our thought of concrete fact.”

“The modern systems view, which flowered during World War II (though building on principles in the wind much earlier), has already borne its first fruits and is in danger of a superficial acceptance into the corpus of sociology by way of the incorporation of some of its now common vocabulary.”

“No device of man can remove the tragedy from war, yet it is a great advance when the guilty have far more to fear from war than the innocent.”
