Yet no man could point out two places in the whole world of more importance to the commonwealth than Thermopylae by land and the Hellespont by sea; and both of them these men have infamously sold and delivered into the hands of Philip. What an enormous offence, apart from all the rest, is the surrender of Thrace and the Thracian outposts, I could show by a thousand reasons; and it would be easy to point to many men who for such betrayals have been sentenced to death or mulcted in large sums of money in this court,—Ergophilus, Cephisodotus, Timomachus, and, in old times, Ergocles, Dionysius, and others, of whom I may say that all of them together had inflicted fewer injuries upon the commonwealth than the defendant.
But in those days, men of Athens, you were still careful to be on your guard against perils, and not sparing of precaution; now you overlook anything that at any given moment does not disturb you or cause immediate annoyance. And then you come here and pass random resolutions,—that Philip shall swear fidelity to Cersobleptes,—that he shall have no share in Amphictyonic business,—that he shall revise the terms of peace. Yet all your resolutions would have been unnecessary, if only the defendant had chosen to travel by sea and to do his duty. What might have been saved by sailing, he has lost by insisting on travel by land; and what might have been saved by telling the truth, he has lost by telling lies.
