Valens

"His father had bought a hundredweight of books from a trader. When Valens was fifteen, he'd told him he could choose five books for his own; the rest would be burned. Valens had read them all, desperately, in a hurry, and made his choice. Varro's "On Statecraft," Yonec's "Art of War," the Sude "Encyclopedia," Statianus on revenues and currency, and the "Standard Digest of Laws & Statutes;" five books, Valens reckoned, that between them contained the bare minimum of knowledge and wisdom a prince needed in order to do his job properly. When he announced that he'd made his choice, his father had had the five books burned and spared the rest; books should be a man's servant, he declared, not his master. Valens wasn't quite sure he saw the point, but he'd learned the lesson, though not perhaps the one his father had intended to convey: that to value anything is to give it an unacceptable degree of power over you, and to choose a thing is to lose it."
