Twentieth Century Moral Philosophy

Despite being somewhat long in the tooth at the time, Aristotle, Hume and Kant were
still dominating twentieth century moral philosophy. Much of the progress made in that
century came from a detailed working through of each of their approaches by the
expanding and increasingly professionalized corps of academic philosophers. And this
progress can be measured not just by the quality and sophistication of moral philosophy
at the end of that century, but also by the narrowing of some of the gaps between
Aristotelian, Humean and Kantian philosophers.
