Existentialism entered the American consciousness like an elephant entering a dark room: there was a good deal of breakage and the people inside naturally mistook the nature of the intrusion. What would it be? An engine of destruction perhaps, a tank left over from the war? After a while the lights were turned on and it was seen to be “only” an elephant; everyone laughed and said that a circus must be passing through town. But no, soon they found the elephant was here to stay; and then, looking closer, they saw that although he was indeed a newcomer, an odd-looking one at that, he was not a stranger: they had known him all along.
