I recommend some of his other works: Whose Justice, Whose Rationality and Dependent Rational Animals.

It’s rewarding to seem him attempt a reconciliation between some modern epistemologies and Augustinian Thomism. I’m not sure he really pulls it off but his stature as a thinker in moral philosophy is undeniable.

Also his very late work, ethics in the conflicts of modernity is often looked over for his older ones but is probably my favorite.

After Virtue is his most important work, I think, but the above titles are the logical follow-ups to read next.
