Whoever loses the capability for inner silence, loses contact to himself and soon won't be able to think clearly any more.

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.

If we lose the ability in question for a single moment only, we are immediately being hijacked by an aggressive little "Think me!" and our mind begins to wander.

I believe that gut feelings, the sense of balance, and spatial self-perception are so firmly coupled to our biological body that we will never be able to leave it experientially on a permanent basis.

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.

Whoever loses the capability for inner silence, loses contact to himself and soon won't be able to think clearly any more.

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