The History of the Peloponnesian War
Page: 106"We must not, therefore, commit ourselves to a false policy through a belief in the efficacy of the punishment of death, or exclude rebels from the hope of repentance and an early atonement of their error. Consider a moment. At present, if a city that has already revolted perceive that it cannot succeed, it will come to terms while it is still able to refund expenses, and pay tribute afterwards. In the other case, what city, think you, would not prepare better than is now done, and hold out to the last against its besiegers, if it is all one whether it surrender late or soon? And how can it be otherwise than hurtful to us to be put to the expense of a siege, because surrender is out of the question; and if we take the city, to receive a ruined town from which we can no longer draw the revenue which forms our real strength against the enemy? We must not, therefore, sit as strict judges of the offenders to our own prejudice, but rather see how by moderate chastisements we may be enabled to benefit in future by the revenue-producing powers of our dependencies; and we must make up our minds to look for our protection not to legal terrors but to careful administration. At present we do exactly the opposite. When a free community, held in subjection by force, rises, as is only natural, and asserts its independence, it is no sooner reduced than we fancy ourselves obliged to punish it severely; although the right course with freemen is not to chastise them rigorously when they do rise, but rigorously to watch them before they rise, and to prevent their ever entertaining the idea, and, the insurrection suppressed, to make as few responsible for it as possible.
"Only consider what a blunder you would commit in doing as Cleon recommends. As things are at present, in all the cities the people is your friend, and either does not revolt with the oligarchy, or, if forced to do so, becomes at once the enemy of the insurgents; so that in the war with the hostile city you have the masses on your side. But if you butcher the people of Mitylene, who had nothing to do with the revolt, and who, as soon as they got arms, of their own motion surrendered the town, first you will commit the crime of killing your benefactors; and next you will play directly into the hands of the higher classes, who when they induce their cities to rise, will immediately have the people on their side, through your having announced in advance the same punishment for those who are guilty and for those who are not. On the contrary, even if they were guilty, you ought to seem not to notice it, in order to avoid alienating the only class still friendly to us. In short, I consider it far more useful for the preservation of our empire voluntarily to put up with injustice, than to put to death, however justly, those whom it is our interest to keep alive. As for Cleon's idea that in punishment the claims of justice and expediency can both be satisfied, facts do not confirm the possibility of such a combination.
