The veneer of civilization, I concluded, was quite thin—a natural thought for an intelligence officer whose profession trends pessimistic and whose work is consumed by threats and dangers. Over the years I had learned that the traditions and institutions that protect us from living Hobbesian "solitary, poor, nasty, brutish and short" lives are inherently fragile and demand careful tending. In America today, they are under serious stress.
It was no accident that the Oxford Dictionaries' word of the year in 2016 was "post-truth," a condition where facts are less influential in shaping opinion than emotion and personal belief. To adopt post-truth thinking is to depart from Enlightenment ideas, dominant in the West since the 17th century, that value experience and expertise, the centrality of fact, humility in the face of complexity, the need for study and a respect for ideas. ~ Michael Hayden, former director of the NSA and CIA, in an op-ed for The New York Times
