Clearly it's a waste of time to try to have a reasoned debate with someone not even willing to consider one's arguments but rather intent on misrepresenting them as directed toward purposes for which they never were intended to serve (e.g. a fleshed-out psychology or comprehensive analysis of the perceptual system).

It's a shame you haven't read Hume's skeptical critiques of empirical claims of "fact," but as I said before, deep epistemology isn't of interest to everyone and isn't relevant to the vast majority of scientific claims that can be made.

Peace.
