As far as inner action is concerned, we are only rarely truly self-determined persons, for the major part of our conscious mental activity rather is an automatic, unintentional form of behavior on the subpersonal level.

I believe that if we would carefully apply the distinction between transparency and opacity to the different layers of the human self-model, looking at self-consciousness in a much more careful and fine-grained manner, then we might also arrive at a new answer to your original question: What a "first-person perspective" really is.

Only as long as we believe in our own identity over time does it make sense for us to make future plans, avoid risks, and treat our fellow human beings fairly - for the consequences of our actions will, in the end, always concern ourselves.

The notion of a conscious model of oneself as an individual entity actively trying to establish epistemic relations to the world and to oneself, I think, comes very close to what we traditionally mean by notions like "subjectivity".

Consciousness is phenomenologically subjective whenever there is a stable, consciously experienced first-person perspective.

Someone who cannot stop his outer flow of words will soon be unable to communicate with other human beings at all.

I could never understand how someone would embark on their life without having first confronted and clarified the truly fundamental questions.
