Walker Percy wrote in Lost in the Cosmos (foreseeing the craze for antidepressants): “Assume that you are quite right [to be depressed].  You are depressed because you have every reason to be depressed.  No member of the other two million species which inhabit the earth – and who are luckily exempt from depression – would fail to be depressed if it lived the life you lead.  You live in a deranged age – more deranged than usual, because despite great scientific and technological advances, man has not the faintest idea of who he is or what he is doing. . . . Consider the only adults who are never depressed: chuckleheads, California surfers, and fundamentalist Christians who believe they have had a personal encounter with Jesus and are saved for once and all.”
