Sách nói: On Duties

On Duties (Latin: DE OFFICIIS) discusses virtue, expediency and apparent conflicts between the two. St. Ambrose, St. Jerome and other Doctors of the Roman Catholic Church considered it to be legitimate for study. It was the second book after the Bible printed on Gutenberg's press and a standard text taught at Eton College. Written by Marcus Tullius Cicero. Translated by Walter Miller.
