Full Idea
The ground for thinking that qualia are only experiences because they relate to a unifying subject is that they have to be identified, by being brought under concepts, and giving rise to judgements which usually go beyond them.
Clarification
'Qualia' are raw unprocessed experiences
Gist of Idea
Qualia must be united by a subject, because they lead to concepts and judgements

A Reaction
Thus one of Hume's greatest fans gives the clearest objection to Hume. It strikes me as a very powerful objection, better than anything Carruthers offers (1394,1395,1396). The conceptual element is very hard to disentangle from the qualia.
