Post-truth” carries a catchy, advertising-agency ring. And that may be exactly what is wrong with it and with our times. We do not live in an era stripped of truths. We live, to the contrary, in a political-cultural moment saturated with competing claims on truth, each insisting on its veracity. We have contrived to construct an open marketplace of truths, and it is not a happy state.
If there can be said to be an era in recent American history when the essence of truth was under critical scrutiny, it was the generation after 1960. In both popular and academic culture, that was when the belief that truth lay in a sphere of certainty independent of truth’s inquirers began to fragment. Social scientists learned to grow much more self-critical about their methods. Anthropologists realized that they could not write themselves out of their ethnographies. Historians learned that archives contained fictions as well as facts. Paradigms, in Thomas Kuhn’s phrase, shaped the very worlds of assumption in which natural scientists worked. None of truth’s seekers, it was increasingly realized, could wholly escape the perspectives and experiences they carried with them. What seemed “natural” was, as often as not, not natural at all but a product of culture and unspoken assumption.
