“That of knight-errantry,” said Don Quixote, “which is as good as that of poetry, and even a finger or two above it.”
“I do not know what science that is,” said Don Lorenzo, “and until now I have never heard of it.”
“It is a science,” said Don Quixote, “that comprehends in itself all or most of the sciences in the world, for he who professes it must be a jurist, and must know the rules of justice, distributive and equitable, so as to give to each one what belongs to him and is due to him. He must be a theologian, so as to be able to give a clear and distinctive reason for the Christian faith he professes, wherever it may be asked of him. He must be a physician, and above all a herbalist, so as in wastes and solitudes to know the herbs that have the property of healing wounds, for a knight-errant must not go looking for someone to cure him at every step. He must be an astronomer, so as to know by the stars how many hours of the night have passed, and what clime and quarter of the world he is in. He must know mathematics, for at every turn some occasion for them will present itself to him; and, putting it aside that he must be adorned with all the virtues, cardinal and theological, to come down to minor particulars, he must, I say, be able to swim as well as Nicholas or Nicolao the Fish could, as the story goes; he must know how to shoe a horse, and repair his saddle and bridle; and, to return to higher matters, he must be faithful to God and to his lady; he must be pure in thought, decorous in words, generous in works, valiant in deeds, patient in suffering, compassionate towards the needy, and, lastly, an upholder of the truth though its defence should cost him his life. Of all these qualities, great and small, is a true knight-errant made up; judge then, Señor Don Lorenzo, whether it be a contemptible science which the knight who studies and professes it has to learn, and whether it may not compare with the very loftiest that are taught in the schools.”
“If that be so,” replied Don Lorenzo, “this science, I protest, surpasses all.”
