[Ghoulish Delight]

Look, I'm a scientist, I know all this. But I will always maintain that the whole of science holds true only if our fundamental perception of the universe is true. And that's something that, by definition, simply cannot be proven or disproven by observational science.

Again, all of this is taken, by me, as a purely mental exercise. I don't believe that our base pereceptions are wrong, but I'm fully cognizant that they could be. I do believe it's possible that what I observe is entirely a product of my own dellusional consciousness, that "reality" is something outside of my observational ability. Of course, I also accept that that doesn't particularly matter and that within the limits of what we can observe, everything you say is true. I don't live my life constantly qualifying everyting with, "Yes, but only if you assume the universe actually exists." But that's just as implicit as Alex's "In my opinion" reviews.
