dexter,
Actually, I'm not saying that just because you don't have 100% certainty of something, you can't believe it. I'm saying you have 0% certainty of something.
Frankly, you don't seem that interested in understanding and engaging Hume's argument, so I'm probably not going to continue much longer, but here's one more whirl. You ask how I'm defining "possible universes," and complain that I can't know that all my various universes (that are not regular tomorrow) are really possible. Well, right back atcha' -- you don't know that the universe that IS regular for one more day is possible, either. We are in ignorance about which universes are possible, including the one that stays ordered. You say we see THIS one. Well, yes, but we don't know whether THIS one is ordered tomorrow, or just up through today. Period.
So the best we can do is list all the possibilities and assign them equal weight.
And when I say "possible universes," I really mean "possible futures for this one universe." If talking of more than one universe offends you, think of it as futures, then. But again -- you can't say that we've seen ANY of the futures, so while it's true that I can't know that any of the disordered possibilities is true, neither can you the ordered one. To turn around an old atheist saw, "You reject the liklihood of all infinitely many possible futures. I just reject one more."
The reason order is less reasonable to expect than disorder is because we can't give any reason to expect any particular outcome, and there are far, far more disordered possible outcomes than ordered ones.
"Justified does not mean 100.00% sureness or clarity... it only means that there is reasonable, sufficient and appropriate support for your position - which clearly there is."
No, there is not. There is ZERO reason to believe that the universe will stay ordered tomorrow. And please don't think this is a novel argument. It's not. Hume popularized it, and it has never been refuted.
"I have (considerable) evidence *and* I have the lack of contrary evidence in my favor.
Yeah, but you're citing evidence for the proposition that evidence is reliable. See how that's circular?
Regards.
