pennywise: actually, the paradigm I've been defending has been 'warranted true belief', rather than JTB. If nothing else, the proposition JTB = Knowledge has been proven false. (Yes, sometimes philosophers prove things false.) Part of the reason for this, and this is an idea going back to Aristotle, is that if you want to understand a phenomenon, you need to understand the basic cases first, and only then look to the aberrant cases. Moreover, I am not a foundationalist, and I would never say "I have a white sense perception". I would say "I see a white thing".
But what if the white thing isn't actually there? Well, then our senses aren't working properly. But we have the fact that we almost always can figure out when our senses aren't working properly (for example, by conferring with other people, testing the perception of the pink elephant against our belief that there are no pink elephants, testing a perception with other senses -- trying to touch the pink elephant.) THis very fact, that we know sometimes our senses deceive us, is evidence that by and large they do not.
