"Man is the only animal who is prone to insanity"
About this Quote
Wilson emerged in postwar Britain, when existentialism was still a live wire and psychiatry was becoming a dominant cultural language. His work (from The Outsider onward) is preoccupied with people who can't quite metabolize ordinary life: the visionary, the misfit, the obsessive. So the line isn't merely bleak. It's a backhanded compliment to the species: only a creature capable of abstract meaning, moral dread, and future-terror can also become unmoored by them.
The subtext is a critique of modernity's thin scripts for living. When the world offers comfort without purpose, stimulation without direction, the mind looks for intensity elsewhere - sometimes by turning on itself. Wilson's provocation is that madness isn't an alien invasion; it's a human feature, the shadow cast by self-awareness.
