On taking leave, Don Quixote said to Don Lorenzo, "I know not whether I have told you already, but if I have I tell you once more, that if you wish to spare yourself fatigue and toil in reaching the inaccessible summit of the temple of fame, you have nothing to do but to turn aside out of the somewhat narrow path of poetry and take the still narrower one of knight-errantry, wide enough, however, to make you an emperor in the twinkling of an eye." In this speech Don Quixote wound up the evidence of his madness, but still better in what he added when he said, "God knows, I would gladly take Don Lorenzo with me to teach him how to spare the humble, and trample the proud under foot, virtues that are part and parcel of the profession I belong to; but since his tender age does not allow of it, nor his praiseworthy pursuits permit it, I will simply content myself with impressing it upon your worship that you will become famous as a poet if you are guided by the opinion of others rather than by your own; because no fathers or mothers ever think their own children ill-favoured, and this sort of deception prevails still more strongly in the case of the children of the brain."
