War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse.

What is human warfare but just this an effort to make the laws of God and nature take sides with one party.

In modern war... you will die like a dog for no good reason.

If we don't end war, war will end us.

I must study politics and war that my sons may have liberty to study mathematics and philosophy.
