Dennett's reliance upon Benjamin Libet's experiment shows how pathetically ignorant he is of where freedom of the will is be found. He thinks it's about acting for no reason; whereas it's acting for a reason, i.e., for a goal. Moving a hand at an unassigned moment is one of the least suitable examples of the exercise of free will that could be conjured up. For free will is an act of choosing between two alternatives that are intelligibly different. Try as I may, I just can't see anything intelligible about the difference between moving my hand now and not moving my hand now. That sort of choice looks less like the product of typical deliberation than it looks like the attempt to act indeliberately, randomly.
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...
