The Art of Tetman Callis

“It is demonstrated in natural law that he who promises another confers on him a perfect right to require the thing promised, & that, consequently, not to observe a perfect promise, is to violate the right of another; it is as manifest injustice as to plunder any one of their right. All the tranquility, the happiness & security of mankind rest on justice, on the obligation to respect the rights of others. The respect of others for our rights of domain & property is the security of our actual possessions; the faith of promises is our security for the things which cannot be delivered or executed on the spot. No more security, no more commerce among men, if they think themselves not obliged to preserve faith, to keep their word.” – Emer de Vattel (as translated by Thomas Jefferson in Jefferson’s “Opinion on the French Treaties,” April 28, 1793)
