- I know that you guys don't think much of the Anthropic Principle -- but I do, and would point out that my argument is something of a variation on that principle. The AP claims that what sets our universe apart from any other potential universes is that ours supports observers.
I assume you mean the Strong Anthropic Principle, rather than the Weak Anthropic Principle. The Weak is pretty much a tautology, and I suspect that every man jack* of us accepts it.
- I should take that back. I was skipping a step. The AP talks directly about the unlikelihood of life in the universe rather than the unlikelihood of observers...
Yes, but the Strong Anthropic Principle isn't part of the standard scientific model, so you can't use it to disprove the standard scientific model. (Unless you can prove it, which I guarantee you can't.) Once again, assuming (arguendo) the scientific model + something else (it was souls last time, if I recall correctly), and then showing that that leads to a contradiction does not disprove the scientific model. It only shows that both can't be true; it still leaves open the possibility that it's the something else that's false.
So, feel free to personally believe in the SAP all you want, but don't pretend that it's a useful part of any sort of proof you might offer us. To perform a reductio ad absurdam of the scientific model, you have to stick to the scientific model.
(I don't know how many times I'm going to have to say this; I suspect a lot.)
I'm not sure you
can show that the SAP + the standard scientific model leads to contradiction, but even if you could, it wouldn't further your so-called proof one bit. It would be a waste of your time and ours.
* or woman jill.
ETA: I might go so far as to say that the Strong Anthropic Principle
is the Texas Sharpshooter Fallacy.
