O powinnościach. Nauki etyczne Cycerona o obowiązku, honorze i cnocie in short
On Duties asks one large question in three steps. Book One says duty grows from reason, the love of truth and the need for fellowship, and it divides honour into wisdom, justice, courage and self-control. Book Two says people prosper through trust and kindness, not fear.
What O powinnościach. Nauki etyczne Cycerona o obowiązku, honorze i cnocie is about
Imagine a statesman who has lost his city. The senate no longer meets, the courts are shut, and a man he fears hunts him. Marcus Tullius Cicero is that man, and he sits down to write a letter to his son.
The letter is On Duties, in three books. His son Marcus studies in Athens, and Cicero wants him to know how to act in every part of life, from business and friendship to war and public office. Cicero's bold answer is that a thing which is truly wrong can never be truly useful.
Dla kogo. Readers who enjoy practical ethics, Roman history and the question of how to act well under pressure, and anyone who likes a wise teacher speaking straight to a young person.
The 11 key ideas

Cicero writes to his son as Rome falls
Cicero wrote On Duties near the end of his life, when the republic he had served was collapsing. Caesar had been killed, the senate no longer governed, and the courts stood closed. Cicero left Rome in 44 BC, afraid of Mark Antony. He could no longer speak in the forum, so he turned to writing.
The book is a letter to his son Marcus, a young man studying in Athens. Cicero urges him to join Greek learning with Latin. He says no part of life, public or private, is free of duty.
He follows the Greek thinker Panaetius, who sorted choices into what is right, what is useful, and what to do when the two clash. Cicero adds the choice between two right acts and between two useful ones. So the work asks five questions across three books. Duty is the practical art of acting on good reasons in every part of life.
