Wasn't the original purpose of the analogy "combatting Intelligent Design (ID) theory"? How does comapring biological evolution to technological development, a process that involves an intelligent agent, combat ID?
That's how I took it and ran with my own version of the argument in posts 1903 and 1906 where my "slap down" of Intelligent Design was that no intelligent agents of the sort we popularly assume, actually exist.
But my slap down was just a breeze from a hair dryer, because the intelligent behavior of goal direction, foresight, and reasoning from causes is more than mere smoke and mirrors. It's the reason humans are such advanced tool makers. Sure, it's all in essence a natural selection, but there's a reason we have the vocabulary about human intelligence.
My next lame version was to grant that intelligent behavior of a more involved sort takes place in human tool making, but that this is an unnecessary detail to my argument. The argument being that intelligent action needn't be called forth. It's a different level of discription that can be ignored in the essential accounting of the process that exhibits just the selecting. All is just selecting.
But the devil is in the details: the details I'm trying to compartmentalize out of the picture. My argument is still trying to say there are no intelligent agents involved. I say, well there are intelligent agents, but they are on a different level of discription, so we musn't take them into account here. I'm hoping to misdirect the ID guy from my denial.
Now if I could show in clear detail how the selection system in human tool making does not involve goal directed behavior, reasoning from causes, and imagination, then I could frame my slap down aright.
So I confess my version of Southwind's approach to be pantywaist and lame.
And I wish others more success framing it in a way that would actually leave ID speechless.
