After Virtue was first published in 1981, but MacIntyre wrote a new preface in 2007 reasserting his full confidence in the arguments. After Virtue promises to take on emotivism and moral relativism generally and to help us navigate not toward moral absolutism but toward moral judgment through a renewal of Aristotelian virtue ethics. This video introduces key themes, including his disagreement with communitarianism, and a bit of the life of MacIntyre–who’s still going at 90– in preparation for a reading of the third edition of After Virtue.
