We must, all of us, learn actually not to have enemies, but only confused adversaries who are ourselves in disguise.
I count him braver who overcomes his desires than him who conquers his enemies; for the hardest victory is over self.
We have real enemies in the world. These enemies must be found. They must be pursued and they must be defeated.
If we cut up beasts simply because they cannot prevent us and because we are backing our own side in the struggle for existence, it is only logical to cut up imbeciles, criminals, enemies, or capitalists for the same reasons.
