Animus in consulendo liber (Latin: "A mind unfettered in deliberation") is the motto of the North Atlantic Treaty Organization (NATO).[1] The phrase is from The Conspiracy of Catiline (52.21) by the Roman historian Sallust, and was translated by Charles Anthon as "a mind unfettered in deliberation".[2]
The motto was chosen by the dean of the NATO Council, André de Staercke , to reflect the spirit of consultation envisioned by the then-Secretary General of NATO Paul-Henri Spaak.[1] De Staercke borrowed the quote when he recalled his visit to the Palace of the Chief Magistrate in San Gimignano, where "animus in consulendo liber" was engraved on the Magistrate's seat.[1] The motto is displayed on the wall of the main council room at NATO headquarters in Brussels, behind the chairman's seat.[1]
The motto's original context by Sallust, who cites Cato the Younger's address to the Roman Senate, is: "But there were other qualities which made them [our forefathers] great, which we do not possess at all: efficiency at home, a just rule abroad, in counsel an independent spirit free from guilt or passion".[3]
