Subjectivity means to catch yourself in the act.

Subjective time flows forward, the phenomenal self is embedded into this flow, an inner history unfolds. That it is why it is not a bubble, but a tunnel: There is movement in time.

The conscious experience of being a subject arises when a single organism learns to enslave itself.

You cannot be a rational subject without veto-control on the level of mental action.

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.

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.

The self is not a thing, but a process.
