John Gray argues for another way of perceiving the world inspired by the fantasy fiction writer Arthur Machen. Instead of believing that meaning in life can only be found by changing things around us, "Some of the most valuable human experiences, Machen observed, come about when we simply look around us without any intention of acting on what we see. He thought of the world as a kind of text in invisible writing, a cipher pointing to another order of things" Producer: Sheila Cook.
