Thucydides (Athenian general and historian, c. 460-400 BCE)
“Haste and anger are, to my mind, the two greatest obstacles to wise counsel – haste, that usually goes with folly, anger, that is the mark of primitive and narrow minds.”
- History of the Peloponnesian War (Book III, 42) by Thucydides, translated by Rex Warner (Penguin Classics, 1972). The quote comes from a speech that Thucydides wrote while in the character of Diodotus.
