We can be totally deprived of all raw data and yet be awash in experience. I think this demonstrates the degree to which this conceptual confusion enters into the topic. When I think of this one I imagine something like Philip's experience when he entered the cathedral. Very much, it seems, like the experience I had when I first saw the Grand Canyon. I would count this experience as very basic to my life but hardly basic to my epistemology, knowledge or belief system.
Experience is part of the process of building a belief system.
It is, in other words, the next step. I have long felt that the Foundationalist program was unnecessary but that has never taken away from it's fascination for me. I remain convinced, as I think some may agree, that any adequate epistemology will need to address the building blocks and their adequacy. Ones which I personally don't think can be resolved adequately. This, it seems, is the direction of R1.
