Chakka, intellectual laziness? Me? Wash your mouth out!! (Gin should do the trick quite nicely). As I've said before, unless we have solid proof that something is fact, then, logically, we can only say we don't know the answer. I want to know the answers, and I do weigh the evidence, but if that is inconclusive, settling for a �reasonable conclusion� is what amounts to intellectual laziness (Occam's Razor rears its head again), since there's a possibility that what might be presumed to be reasonable today may prove to be totally incorrect tomorrow. If I don't have the answer, I'm not going to invent it by accepting any conclusion, reasonable or otherwise, and therefore I have no alterative but to keep an open mind.
I'll look at the thread in Science you mentioned later - and possibly throw in my two-pennorth.
(Yes, I�ve finished. Have you? I'm feeling quietly confident, but am probably just about to fall flat on my face!). :o/
