Philosopher Alasdair MacIntyre, in his 1981 book "After Virtue," argues that moral discourse since the Enlightenment is not rational and therefore empty. He believes the reason for this is that the morals of the Enlightenment lack purpose - teleology. The scientific revolution, armed with Darwinism, brought an end to "purpose." One was left to define morality on their own terms. This led to the moral relativism of the individual.  But now a new tribalism has returned, with the left-brain, visually oriented individualism of the Enlightenment giving way to the right-brain, auditory tribalism of the Global Village.  And with it a return to moralistic thinking.   Hegel believed that morals consisted of group ethics that progressed over time, centered in one's family, one's socials spheres and communities, and the state itself. Perhaps the Hegel Renaissance seen over the last few decades is a result of the correspondence of his teachings to this new reality.
