Charles Maurice de Talleyrand Quotes
If we go on explaining we shall cease to understand one another.
Cooper, Duff. Talleyrand. Jonathan Cape, 1932, p. 234.
The principle seems to have been generalized from the military field to include executive orders, diplomatic instructions, policy statements and the like.
Charles-Maurice de Talleyrand-Périgord, 1st Prince of Benevento, then Prince of Talleyrand, was a French clergyman and leading diplomat. After studying theology, he became Agent-General of the Clergy in 1780. Just before the French Revolution, he became Bishop of Autun. He worked at the highest levels of successive French governments, most commonly as foreign minister or in some other diplomatic capacity. His career spanned the regimes of Louis XVI, the years of the French Revolution, Napoleon, Louis XVIII, and Louis-Philippe. Those Talleyrand served often distrusted him but, like Napoleon, found him extremely useful. The name "Talleyrand" has become a byword for crafty, cynical diplomacy.
