A correspondent asked about “specified complexity” and the intelligent design of the eye. I explained why I much prefer the phrase “purposeful arrangement of parts” as a criterion for design — versus irreducible complexity, specified complexity, specified small probability, information, complex specified information, or other phrases.
The critical difference between ID and Darwinian evolution (and all other proposals for unintelligent evolutionary processes) is the involvement of a mind in ID. The philosopher Lydia McGrew once wrote that the basic question of ID boils down to the question of “other minds.” One of Alvin Plantinga’s claims to fame is that he argued fifty years ago in God and Other Minds that (I paraphrase) the perception of the existence of God is the same sort of problem as the perception of the existence of other minds.Michael Behe, “Recognizing Design by a “Purposeful Arrangement of Parts”” at Evolution News and Science Today (June 10, 2021)
“Purposeful arrangement of parts” is actually much easier for the average person to understand.
