@Cyracuz,
Quote: But when we evaluate our own internal processes, as we do in trying to identify and define 'self', we find that there is no object behind the idea.
Maybe the self doesn't like to be self-evaluated, and keeps in hiding... Only half-joking here: my take is the self is very bad at looking at itself, its only Darwinian advantage being in looking at the world.
In any case, if there is no self, there is no subject, and hence no subjectivity.
