Natural scientists aspire to be able to explain nature in quantitative terms : that is, terms of its common sensible characteristics as well as the force, and other quantifiable characteristics needed to explain changes in common sensible characteristics. out the recognition of the qualitative features of experience. Thomas Nagel recognized this problem in his article "What's it like to be a Bat?" That article points out that scientific knowledge of how a bat perceives can never convey the experience that a bat has from a bat's point of view. These perceptual notes are called qualia what it's like for a to perceive, so that if we never perceive things the way a bat does, we wouldn't know how to point out that part of nature that indicates that, when you've then you will leave out the recognition of the qualitative features of nature or experience, including the proper-sensibles. But that is not to say that these qualia are immaterial. Rather, it may indicate that nature itself (including perception and much more) possesses qualia
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...
