However Dembski’s argument suffers from the same fundamental flaw as Behe’s: Dembski, on the other hand, wants to measure the information exhibited by a given phenomenonand from that make an inference about the causal process which produced the phenomenon.


Very well written book luncch the state and direction of the intelligent design movement. In doing so, he alleges, the programmer has “smuggled” complex specified information or specified complexity into the result.
