Thucydides (c. 460-400 BCE)
“It is more disgraceful, at least for those who have a name to lose, to gain one’s ends by deceit which pretends to be morality than by open violence.”
- From a speech attributed to Brasidas in the History of the Peloponnesian War (Book IV, section 86) by Thucydides, translated by Rex Warner (Penguin Classics, 1972).
