If higher level operations were principled by lower operations rather than by a higher level of being, then those (higher level) operations would merely be an effect of the interactions of lower level beings: they would be epiphenomenal. And if epiphenomenal, then agency would be an illusion. But if agency is not illusory, it is not epiphenomenal and higher level operations are not the effect of lower level operations. The only alternative is that there is a higher level of being present. But how does that relate to the lower--as being is to capacity?
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...
