"Knights-errant knew and ought to know everything, Sancho," said Don Quixote; "for there were knights-errant in former times as well qualified to deliver a sermon or discourse in the middle of an encampment, as if they had graduated in the University of Paris; whereby we may see that the lance has never blunted the pen, nor the pen the lance."
-De todo sabían y han de saber los caballeros andantes, Sancho -dijo don Quijote-, porque caballero andante hubo en los pasados siglos que así se paraba a hacer un sermón o plática, en mitad de un campo real, como si fuera graduado por la Universidad de París; de donde se infiere que nunca la lanza embotó la pluma, ni la pluma la lanza.
