Famous quotes containing the word regiment:
“Christians would show sense if they dispatched these argumentative Scotists and pigheaded Ockhamists and undefeated Albertists along with the whole regiment of Sophists to fight the Turks and Saracens instead of sending those armies of dull-witted soldiers with whom they’ve long been carrying on war with no result.”
—Desiderius Erasmus (c. 1466–1536)
