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.

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.

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

Subjectivity means to catch yourself in the act.

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

What many people don't see is that there are abundant examples of phenomenal opacity: It is one of the most interesting features of the human conscious model of reality that, first, it can contain elements that are not experienced as mind-independent, as unequivocally real, as immediately given, and second, that there is a "gradient of realness" in which one and the same content can be experienced transparently or in an opaque fashion.

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