I thought this was well said:
Postmodernity, in reaction to Enlightenment’s enthronement of human reason and back of that, Christianity’s logos epistemology, according to which God places in every human the capacity for objective reason and logic, shifted attention to emotion and feelings as the driving forces in human thought and action. Related to this shift was the adoption of relativism: truth and facts and morals are not absolute but are always culturally and situationally dependent.
A Staple of the West
Friedrich Nietzsche was one of the first to elaborate on these themes, but they’ve become a staple of the West, particularly since the 60’s. At their most beneficial, these views remind us that we are not an exclusively reason-driven species (the Bible never taught that anyway), and at worst suggest that reason is simply a tool of deep (and sometimes malignant) emotions and that we can never arrive at objective truth to boot. The upshot is that reason and truth are in the dock, constantly having to defend themselves, while emotions and feelings and relativism get an unlimited supply of reloadable get-out-of-jail-free cards.
