WHAT WE ARE TO THINK OF THE PRICE IN THE BUYING OF BOOKS

From what has been said we draw this corollary welcome to us, but
(as we believe) acceptable to few: namely, that no dearness of
price ought to hinder a man from the buying of books, if he has
the money that is demanded for them, unless it be to withstand
the malice of the seller or to await a more favourable
opportunity of buying. For if it is wisdom only that makes the
price of books, which is an infinite treasure to mankind, and if
the value of books is unspeakable, as the premises show, how
shall the bargain be shown to be dear where an infinite good is
being bought? Wherefore, that books are to be gladly bought and
unwillingly sold, Solomon, the sun of men, exhorts us in the
Proverbs: Buy the truth, he says, and sell not wisdom. But what
we are trying to show by rhetoric or logic, let us prove by
examples from history. The arch-philosopher Aristotle, whom
Averroes regards as the law of Nature, bought a few books of
Speusippus straightway after his death for 72,000 sesterces.
Plato, before him in time, but after him in learning, bought the
book of Philolaus the Pythagorean, from which he is said to have
taken the Timaeus, for 10,000 denaries, as Aulus Gellius relates
in the Noctes Atticae. Now Aulus Gellius relates this that the
foolish may consider how wise men despise money in comparison
with books. And on the other hand, that we may know that folly
and pride go together, let us here relate the folly of Tarquin
the Proud in despising books, as also related by Aulus Gellius.
An old woman, utterly unknown, is said to have come to Tarquin
the Proud, the seventh king of Rome, offering to sell nine books,
in which (as she declared) sacred oracles were contained, but she
asked an immense sum for them, insomuch that the king said she
