The Greek historian Thucydides, in his History of the Peloponnesian War, gave the following account of an Athenian’s appeal to representatives of the small island of Melos, to join Athens in its war against Sparta:
You know as well as we do that, in the logic of human nature, right only comes into question where there is a balance of power, while it is might that determines what the strong exhort and the weak concede. . . . Your strongest weapons are hopes yet unrealized, while the weapons in your hands are somewhat inadequate for holding out against the forces already arranged against you. . . . Reflect that you are taking a decision for your country, a country whose fate hangs upon a single decision right or wrong.
