Edith Hamilton on Thucydides

“Power, Thucydides wrote, or its equivalent wealth, created the desire for more power, more wealth. The Athenians and the Spartans fought for one reason — because they were powerful, and therefore were compelled (the words are Thucydides' own) to seek more power. They fought not because they were different — democratic Athens and oligarchical Sparta — but because they were alike. The war had nothing to do with differences in ideas or with considerations of right and wrong. Is democracy right and the rule of the few over the many wrong? To Thucydides the question would have seemed an evasion of the issue. There was no right power. Power, whoever wielded it, was evil, the corrupter of men.”

“Thucydides saw that the foundation stone of all morality, the regard for the rights of others, had crumbled and fallen away. It had been the acknowledged foundation when Euripides wrote the Suppliants, not only of dealings between man and man, but also between state and state. The state embodied the idea of honorable men. But when Thucydides wrote, Athens had won an empire by dismissing that idea. In the big business of power politics it was not only necessary, it was right, for the state to seize every opportunity for self-advantage. Thucydides was the first probably to see, certainly to put into words, this new doctrine which was to become the avowed doctrine of the world. He makes Pericles explicitly deny that fair dealing and compassion are proper to the state as they are to the individual. A country pursuing her own way with no thought of imposing that way on others might, he points out, keep to such ideas, but not one bent upon dominion. "A city that rules an empire," he writes, "holds nothing which is to its own interest as contrary to right and reason."”
