Bartlet on Poor Design, ID

Intelligent Design: "Professor Bartelt writes:
if we assume that Behe is correct, and that humans can discern design, then I submit that they can also discern poor design (we sue companies for this all the time!). In Darwin's Black Box, Behe refers to design as the 'purposeful arrangement of parts.' What about when the 'parts' aren't purposeful, by any standard engineering criteria? When confronted with the 'All-Thumbs Designer' - whoever designed the spine, the birth canal, the prostate gland, the back of the throat, etc, Behe and the ID people retreat into theology.* [I.e., God can do whatever it wants, or We're not competent to judge intelligence by a god's standards, or being an intelligent designer does not mean being a good or perfect designer.]"
