For a human being, to possess a consciously experienced first-person perspective means to have acquired a very specific functional profile and distinctive level of representational content in one's currently active phenomenal self-model: It has, episodically, become a dynamic inner model of a knowing self.

As a philosopher, you define constraints for any good theory explaining what you are interested in, then you go out and search for help in other disciplines.

Subjectivity is an ability, the capacity to use a new inner mode of presenting the fact that you currently know something to yourself.

Virtual reality is the representation of possible worlds and possible selves, with the aim of making them appear as real as possible - ideally, by creating a subjective sense of "presence" and full immersion in the user.

The Ego is a transparent mental image: You, the physical person as a whole, look right through it. You do not see it. But you see with it.

A lot of evidence shows that most of our cognitive processing is unconscious - phenomenal experience is just a very small slice or partition of a much larger space in which mental processing takes place.

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.
