As for the fact, then, that Philip rose to greatness from small and humble beginnings, that the Greek states are mutually disloyal and factious, and that the increase of Philip’s power in the past was a far greater miracle than the completion of his conquests now that he has already gained so much, these and all such topics on which I might expatiate, I will pass over in silence.
I observe, however, that all men, and you first of all, have conceded to him something which has been the occasion of every war that the Greeks have ever waged. And what is that? The power of doing what he likes, of calmly plundering and stripping the Greeks one by one, and of attacking their cities and reducing them to slavery.
Yet your hegemony in Greece lasted seventy-five years, that of Sparta twenty-nine, and in these later times Thebes too gained some sort of authority after the battle of Leuctra. But neither to you nor to the Thebans nor to the Lacedaemonians did the Greeks ever yet, men of Athens, concede the right of unrestricted action, or anything like it.
On the contrary, when you, or rather the Athenians of that day, were thought to be showing a want of consideration in dealing with others, all felt it their duty, even those who had no grievance against them, to go to war in support of those who had been injured; and again, when the Lacedaemonians had risen to power and succeeded to your position of supremacy, and when they set to work to encroach on others and interfered unduly with the established order of things, all the Greeks were up in arms, even those who had no grievance of their own.
