Peace is not mere absence of war, but is a virtue that springs from force of character.
If you want peace, prepare for war.
There is no principle worth the name if it is not wholly good. I swear by non-violence because I know that it alone conduces to the highest good of mankind, not merely in the next world, but in this also. I object to violence because, when it appears to do good, the good is only temporary, the evil it does is permanent.
