Wilson rationalized the psychological dislocation so characteristic of Western creative thinking into a coherent theory of alienation, and defined those affected by it as a type: the Outsider. Through the works and lives of various artists - including Kafka, Camus, Hemingway, Hesse, Lawrence, Van Gogh, Shaw, Nietzsche and Dostoevsky - Wilson explored the psyche of the Outsider, his effect on society and society's on him. Nothing that has happened in the past four decades years has made The Outsider any less relevant; it remains the seminal work on this most persistent of modern-day preoccupations.
