If there is direct experience it is an irruption of the real, a lightning strike a few feet away, a crash, an explosion that knocks you off your feet. Anything else is anticipated, pre-digested, buffered and entirely conceptual. It doesn't feel that way though. The distinction between immediate and mediated experience is a concept intrinsic to mediated experience. However your naturalistic metaphysics or anti-metaphysics works it relies on the work of this distinction, that's what maintains the frame. That you can imagine a certain sustained introspection will deliver up little bursting specks of the real proves the point by the very imbalance of the crafted instrument you need to put into play with the presumed naivety of the product. Still, there is some point in assaying experience for its fragments of reality, as long as you know that such reality is only currency.
