Panegyricus (182-185)

—it is disgraceful for us, I say, now that all Hellas is being continually outraged, to take not a single step to wreak a common vengeance, although we have it in our power to accomplish deeds as lofty as our dreams. For this war is the only war which is better than peace; it will be more like a sacred mission than a military expedition; and it will profit equally both those who crave the quiet life and those who are eager for war; for it will enable the former to reap the fruits of their own possessions in security and the latter to win great wealth from the possessions of our foes.

You will find, if you weigh the matter carefully, that this undertaking is most desirable for us from many points of view. For against whom, pray, ought men to wage war who crave no aggrandizement, but look to the claims of justice alone? Is it not against those who in the past have injured Hellas, and are now plotting against her, and have always been so disposed towards us?

And against whom should we expect men to direct their envy who, while not wholly lacking in courage, yet curb this feeling with prudence? Is it not against those who have compassed powers that are too great for man, and yet are less deserving than those who are unfortunate among us? And against whom should those take the field who both desire to serve their gods and are at the same time intent on their own advantage? Is it not against those who are both their natural enemies and their hereditary foes, who have acquired the greatest possessions and are yet, of all men, the least able to defend them? Do not the Persians, then, fulfill all these conditions?

Furthermore, we shall not even trouble the several states by levying soldiers from them—a practice which now in our warfare against each other they find most burdensome. For it is my belief that those who will be inclined to remain at home will be far fewer than those who will be eager to join this army. For who, be he young or old, is so indolent that he will not desire to have a part in this expedition—an expedition led by the Athenians and the Lacedaemonians, gathered together in the cause of the liberty of our allies, dispatched by all Greece, and faring forth to wreak vengeance on the barbarians?
