It treats experiences as ‘objects’ or things in their own right: the kind of thing that might float around, unowned, waiting to be scooped into a bundle with some others, like sticks lying in a forest. But, the objection continues, this is a mistake, for experiences are parasitic, or adjectival on persons who have them.
This is a false objection. If there is no self proper, there is no “I” having experiences, but only experiences, thoughts, feelings, sensations themselves. These things are not parasitic to the self but exist in and of themselves.
