At one point he affirms a kind of law of conservation of information, but at another point he says that a simple roll of the dice can increase the amount of information. Is the latter an exception because of the role of a human intelligence? But that intelligence did not know the outcome: it could have been replaced by a dice rolling machine, etc. Or a natural event could have caused the dice to roll. In such a case, would information have been increases or decreased?
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...
