This lecture discusses key ideas from the ancient philosopher and statesman Marcus Tullius Cicero's work, On Duties (De Officiis), which presents a largely Stoic view on ethics, virtues, relationships, and duties or moral obligationsSpecifically it examines whether a person can commit injustice through failing to act. Cicero's answer is that this is indeed possible, and he discusses several motives for this, including the seemingly positive one of being exclusively concerned with philosophy.To support my ongoing work, go to my Patreon site - www.patreon.com/sadlerIf you'd like to make a direct contribution, you can do so here - www.paypal.me/ReasonIO - or at BuyMeACoffee - www.buymeacoffee.com/A4quYdWoMYou can find over 2000 philosophy videos in my main YouTube channel - www.youtube.com/user/gbisadlerPurchase Cicero's On Duties - amzn.to/2xYHJLN(Amazon links are associate links.
