I certainly ain't fer dualism, but I think that merely pointing to the complexity of the brain or to correlations between processes taking play its parts and reported is not sufficient to destroy dualism. I prefer to look for a more robust refutation, and in that spirit, I would first offer an (ironic) defense of dualism of the sort that would recognize the need for the complexity of operation in the brain. The argument that defeats this not-so-lame version of dualism is one that gives us insights into an alternative to both dualism AND to materialistic monism.
Integral to Dembski's idea of specified complexity (SC) is the notion that something extrinsic to evolution is the source of the specification in how it develops. He compares SC to the message sent by space aliens in the movie "Contact." In that movie, earthbound scientists determine that radio waves originating in from somewhere in our galaxy are actually a signal being sent by space aliens. The scientists determine that these waves are a signal is the fact that they indicate prime numbers in a way that a random occurrence would not. What is interesting to me is the fact that Dembski relies upon an analogy with a sign rather than a machine. Like a machine, signs are produced by an intelligent being for the sake of something beyond themselves. Machines, if you will, have a meaning. Signs, if you will, produce knowledge. But the meaning/knowledge is in both cases something other than the machine/sign itself. Both signs and machines are purposeful or teleological...
