o, "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 some one 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,
Senor 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."

"How, if that be so?" said Don Quixote.

"What I mean to say," said Don Lorenzo, "is, that I doubt whether there
are now, or ever were, any knights-errant, and adorned with such
virtues."

"Many a time," replied Don Quixote, "have I said what I now say once
more, that the majority of the world are of opinion that there never were
any knights-errant in it; and as it is my opinion that, unless heaven by
some miracle brings home to them the truth that there were and are, all
the pains one takes will be in vain (as experience has often proved to
me), I
