Well, let's fix the problem. We'll have a machine measure the liquid. When it measures out 51ml, it will stop pouring the liquid. The problem is that we first need to calibrate the machine so that it knows what 51ml is. And who gets to do that? Some subjective human being, of course. And we're right back to square one.
But we can argue that whereas most people will agree on whether it is 50ml or 51ml, it is more difficult to get a majority of people to agree of whether something is designed or not. So then the question of objectivity or subjectivity becomes a relativistic one: how easy is it to get a majority of people to agree on something?
So if ID advocates could get a majority of people to agree that something was designed, then it would be objective and science? I doubt that Mike would agree with this. I'm curious what his response would be.
