Montesquieu

The finest peace treaty of which his­tory has spo­ken is, I believe, the one that Gelon made with the Carthaginians. He insis­ted they abo­lish the cus­tom of sacri­fi­cing their chil­dren.1 How extra­or­di­nary ! After defea­ting three hun­dred thou­sand Carthaginians, he impo­sed a condi­tion that was use­ful only to them, or rather he was nego­tia­ting for the human race.
