Terry Eagleton's tribute to Alasdair MacIntyre is the best I've read so far:
All this makes MacIntyre one of the great moral philosophers of the 20th century. He was a radical Scottish puritan, austere and high-minded, who ended up supporting the revival of monasticism and switched his sympathies from the Bolsheviks to St Benedict. His dissent from the priorities of the modern age took an incongruous variety of forms but remained wholly self-consistent. If he turned back to Aristotle and Aquinas, it was in order to move beyond what he saw as the scepticism and subjectivism of the present. His work showed up the limits of rationalism, but was deeply averse to the irrational. It could win praise from both Leftists and conservatives, but gave no comfort to neoliberalism. MacIntyre refused to subscribe to the view that the individual was at the centre of the universe; that reason is timeless and independent of practical social life; and that relations are primarily contractual and actions chiefly instrumental. In contrast with a mean-spirited utilitarianism, he saw society not as a means of individual self-promotion but as a good in itself. He was interested in practices like playing chess or writing poetry whose goods, as he would say, were “internal” to themselves rather than external goals to be pursued.
