Here is part 2 of my summary of Stephen Meyer’s response to key objections raised against ID (read part 1).  This post will conclude my review/summary of Meyer’s book.  Links to the entire series: 1, 2, 3, 4, 5, 6, 7a.

“ID is an argument from ignorance”

Not at all.  Arguments from ignorance take the following form: X cannot explain Y, therefore Z does.  That is not the form of ID arguments.  ID does not reason that if all naturalistic proposals fail, ID must be true by default.  There are positive evidences provided for inferring design in the universe/biology.  We are not ignorant of how information arises.  We also know from experience that only intelligent designers are capable of producing information (functional, complex specificity).  So postulating an intelligent designer to explain the biological information we observe in the cell is based on what we know, not what we don’t.  If chance and necessity are not adequate to explain the origin of biological information, whereas intelligent agency is, then it is reasonable to view intelligence is the best explanation.[1]

“Doesn’t this presuppose a naturalistic explanation won’t be found in the future?” 

No, it doesn’t.  It merely recognizes that our conclusions should be based on the evidence available to us in the present, not hypothetical evidence that might possibly be discovered in the future.  We must reason to the best explanation given our current data, and our current data gives us no reason to believe life originated by purely naturalistic means, but good reason to believe its origin is due to the activity of a designing intelligence.
