Sorry for the somewhat personal and idiosyncratic review.
Not my favourite collection of articles by MacIntyre, much less indispensable than the first volume in my opinion, for example. Of course it still contains gems and some amount of greatness.
The first part, "Learning from Aristotle and Aquinas" contains the first four papers of the book. MacIntyre is always great as a historian and the first three papers deliver in that regard. Very informative, precise, critical and analytical, on Renaissance, Modern and Thomistic receptions of Aristotle. However, the fourth and only previously unpublished paper of the book might be the worst text I have read of MacIntyre - which, admittedly, is not saying a lot. I see it as a very abstract treatment - in the bad sense of the term - of very serious and concrete matters (on rational disagreement and abortion) and I think it muddies the water regarding those issues rather than illuminating them. It also appears to me as one of the most dogmatically thomistic of his works.
The next three papers, forming the second part of the book, "Ethics", are what I've read of MacIntyre that indeed most resemble a contribution to contemporary ethical philosophy. For this very reason, I tend to find them less helpful and less interesting, as my love for MacIntyre really stemmed from my disdain for contemporary ethical philosophy. I mean that I tend to find contemporary ethics to be in fact more obfuscating than illuminating, and here more than elsewhere MacIntyre "plays ball" and enters the obfuscating arena.
The third part regards "The politics of Ethics", a subject in which I think MacIntyre usually shines, and here lies a lot of good stuff, though nothing particularly new or more compelling than can be found elsewhere. The piece on Years might be the most intriguing, as I have indeed read too little of what MacIntyre has to say about arts, but it has always been greatly interesting.
