John Searle, in his book [b:Mind: A Brief Introduction|51905|Mind A Brief Introduction|John Rogers Searle|http://d202m5krfqbpi5.cloudfront.net/books/1348671049s/51905.jpg|50644], says the following: "...among most of the professionals in the field, substance dualism is not regarded as a serious possibility. A prominent exception is the defense of dualism offered by Karl Popper and J. C. Eccles. They claim that there are two quite distinct worlds, World 1 of physical objects and states and World 2 of states of consciousness. Each is a separate and distinct world that interacts with the other. Actually they go Descartes one better and also postulate World 3, a world of 'culture in all its manifestations.'"
Well, the least I can say is that I am excited to see how Popper's claim passes his falsifiability test, or would he call me a "Popperazzi" too?
