"Peace, if it ever exists, will not be based on the fear of war, but on the love of peace. It will not be the abstaining from an act, but the coming of a state of mind."

If there were only some way of contriving that a state or an army should be made up of lovers and their beloved, they would be the very best governors of their own city, abstaining from all dishonour, and emulating one another in honour; and when fighting at each other's side, although a mere handful, they would overcome the world. For what lover would not choose rather to be seen by all mankind than by his beloved, either when abandoning his post or throwing away his arms? He would be ready to die a thousand deaths rather than endure this.
