Alexander of Aphrodisias: Ethical Problems [PDF ebook] 

Aristotle”s
Nicomachean Ethics has been a central text in moral philosophy since the fourth century BC. The Ethical Problems attributed to Alexander of Aphrodisias – the leading ancient commentator on Aristotle – not only shows us how Aristotle”s work was discussed in Alexander”s own day (c. 200 AD) but offers interpretations and insights that are valuable in their own right. Topics discussed include pleasure and distress, moral virtue, the criteria for judging actions voluntary, the development of moral understanding, and the place in ethics of utility, political community and a sense of shame.
