A lot of famous philosophers have adopted the notion that the mind is "non-physical". This is the dualism of Descartes. I admit that it may be true that there is another realm in the Universe which is so different from the physical world that it needs to be treated as an independent component. But may be is not is. I side with Spinoza and many others on this issue.

Precognition as well as other "psi phenomena" such as clairvoyance, telepathy, and telekinesis may actually exist. Few serious students of psychology, which is after all the current name for the study of the mind, believe that there is sufficient evidence for any of the psi phenomena. However, there is a very good book, "The Conscious Universe", by Dean Radin, that reviews the evidence from the late nineteenth century to the early twenty-first and comes down firmly in favor of accepting these phenomena as real. Real means that if you do the experiments and do them properly you get the same results time and time again and it is no longer possible to declare that psi phenomena don't exist. But the book also relates the mysterious existence of these events to quantum physics. This would keep the mind with all its properties in the physical realm. I just happen to favor this idea. I certainly may be wrong, though. I'm not special. I have thought about these problems since the age of twelve, if that's worth anything.
