For as yet it is by no means evident that if we do as we are bidden we shall henceforth enjoy lasting peace. For I think you are not unaware that all men are wont to discuss just terms with those who defend their rights, while in the case of those who are over-ready to do what they are commanded they keep adding more and more to the conditions which at first they intended to impose; and thus it happens that men of a warlike temper obtain a more satisfactory peace than those who too readily come to terms.
