Alasdair MacIntyre is the most famous contemporary proponent of Aristotelianism, and has been so ever since the publication in 1981 of After Virtue: A Study in Moral Theory. Although he soon thereafter identified his Aristotelianism with the Thomistic tradition, his position remains distinctive in what he says of rivalry between traditions, of the merits of Marxism and phenomenology, and in opposition to modern moral and political  theory and to its institutionalized practice. He is now Senior Research Fellow in CASEP, researching into common goods and political reasoning. His arguments are critically scrutinized, elaborated and applied in the work of the International Society for MacIntyrean Enquiry.
