A nation is as great, and only as great, as her rank and file.

It recognizes no morality but a sham morality meant for deceit, no honor even among thieves and of a thievish sort, no force but physical force, no intellectual power but cunning, no disgrace but failure, no crime but stupidity.

There is no more subtle dissolvent of morals than sentimentality.

It is not men that interest or disturb me primarily; it is ideas. Ideas live; men die.

We are expected to put the utmost energy, of every power that we have, into the service of our fellow men, never sparing ourselves, not condescending to think of what is going to happen to ourselves, but ready, if need be, to go to the utter length of self-sacrifice.

I can predict with absolute certainty that within another generation there will be another world war if the nations of the world do not concert the method by which to prevent it.

Let me... remind you that it is only by working with an energy which is almost superhuman and which looks to uninterested spectators like insanity that we can accomplish anything worth the achievement. Work is the keystone of a perfect life. Work and trust in God.
