The idea that there are distinct epochs of history, each with distinct types of humanity, each having distinct understandings of the world that are somehow explained by the characteristics of that epoch, has a long history. Nietzsche gave us the noble soul and the resentful soul, the former predominating in the pre-Socratic age, the latter prevailing from Christianity down to the present moment. Before him, Marx gave us feudal man and capitalist man, the former able to understand the plurality of values, the later who reduced that plurality to the monovalent measure of money. Further back, Kant gave us the archaic man, who treated others as means, followed by cosmopolitan man, who treated others as ends. Rousseau gave us ancient man, who was oriented by virtue, and modern man, who is oriented by interests. Luther, working within a biblical framework, gave us Old Testament Man, oriented by the Law, and New Testament man, oriented by the Gospel. Augustine gave us that formulation as well, though more moderately formulated, which left open the way for Aquinas to leave his indelible mark on the Roman Catholic Church.
