No matter how basic it gets, experience is not data. Experience is experience.
Experience is subjective by definition.
Experience is always interpreted and, to my way of thinking, never basic. It certainly cannot be the basis building block of knowledge. Far from being indubitable it seems to me to be the most dutiable of all experience. It stops being data as soon as it becomes experience. At least when we close our eyes the data stops, when we turn out the light the data stops, when we stop up our ears the data stops.
