So just to clarify, you would never participate in any hypothetical question, nor would you ever make a comment like "we would have won if Gronk were healthy" or any statement along those lines? Because your logical proof applies to all of those scenarios, and I would hate to think you are being a hypocrite in attacking this thread for no apparent good reason.
Whoa! Using a word like "hypocrite" and construing my comment as "attacking" the thread is way off base. The thread posed a question, to which the opening post suggested the answer was open. In that spirit, I gave a response.
But, to answer your question and take it seriously, yes, the logic does hold (and, BTW, it's not "my" logic, but rather a tiny part of a systematic logical framework that has been around for a couple millennia and expounded by minds far greater than mine). Sometimes, it actually has practical applications.
Here's the point. If we're speculating on an outcome based on a circumstance that did not occur, yes, we are always dealing with the unknowable. Positing the unknowable as a premise creates a situation in which anything that follows from the premise, when considered together with the premise, forms a statement that, by the rules of logic, is always a "True" statement.
The practical implication of this is that the logical answer to the posited question or any similar question is, by definition, "Maybe. Maybe not." If that's "attacking" and I'm some kind of a "hypocrite" then, I'm guilty as charged.
As
Bruins29 and I ultimately agreed (after his very thoughtful initial comment on my post and our subsequent exchange about it above) it does make for what many would consider to be an interesting discussion. But, ultimately we're dealing with what is unknowable.
Would the Pats have won XLVI if Gronk had been healthy? "Maybe. Maybe not." That could be an interesting discussion, but, the answer is ultimately unknowable and demands speculation. Does that mean we don't engage in it? No. Does it mean that I, speaking personally, don't think it's worth spending a lot of time on it? Yes, but I wouldn't demean others who do so extensively engage (and certainly wouldn't call them names).
Would the Seahawks have won XLIX if Avril had not left the game? Or if several other members of the D weren't playing hurt? "Maybe. Maybe not." Another discussion of what is unknowable, which many could find interesting but on which I'm not interested in spending a lot of time.
That's my point, no more. No less.
