"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.""
