This is one of the clearest accounts I've ever read about the mystery of consciousness, and the way in which one theory about it, panpsychism, does a great deal to explain how it occurs and what it is. Why shouldn't consciousness be a normal property of matter, like mass or electrical charge? This idea has the glorious simplicity of our first realisation that the earth goes around the sun, and not vice versa. Suddenly the universe appears in a new and much more revealing perspective. Philip Goff's book is altogether a splendid introduction to this fascinating idea.
