Here is a warning, men of Athens , which, if you will be guided by me, you will bear in mind; and, remembering also that, when Philip was besieging Amphipolis , he pretended to be doing so in order to hand the place over to you, but that, when he had got it, he annexed Potidaea into the bargain, you will sh to have the same sort of assurance that, according to the story, Philocrates, son of Ephialtes, once opposed to the Lacedaemonians. It is said that, when the Lacedaemonians were trying to overreach him, and offered any assurance he was willing to accept, Philocrates replied that the only possible assurance would be that they should satisfy him that, if they had a mind to injure him, they would not have the power; for, he added, I am quite certain that you will always have the mind, and there can be no assurance so long as you have the power. That,—if you will let me advise you,—is the sort of assurance that you will hold against this Thracian. If he ever became master of all Thrace , you need not inquire what his sentiments toward you would be. That it is entirely the act of insane men to compose such decrees, or to bestow such favours as this, may easily be learned from many examples. I am sure, men of Athens , that you all know as well as I do that you once admitted Cotys over yonder to your citizenship, evidently because you regarded him at the time as a sincere well-wisher. Indeed, you decorated him with golden crowns; and you would never have done that, if you had thought him your enemy. Nevertheless, when he was a wicked, unprincipled man, and was doing you serious injury, you treated the men who put him to death, Pytho and Heracleides of Aenos , as benefactors, made them citizens, and decorated them with crowns of gold. Now suppose that, at the time when the disposition of Cotys was thought to be friendly, it had been proposed that any one who killed Cotys should be given up for punishment, would you have given up Pytho and his brother? Or would you, in defiance of the decree, have given them your citizenship, and honored them as benefactors? Again, there was Alexander of Thessaly . In 368 Alexander, tyrant of Pherae, detained Pelopidas as a hostage. This led to the Theban invasion of Thessaly . At the time when he had imprisoned Pelopidas, and was holding him captive, when he was the most bitter enemy of the Thebans, when his feelings towards you were so fraternal that he applied to you for a commander, when you gave aid to his arms, when it was Alexander here and Alexander there,—why, gracious heavens! if anybody had moved that whoever killed Alexander should be liable to seizure, would it have been safe for any man to try to give him due punishment for his subsequent violence and brutality?
