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

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

In ordinary life, the phenomenology of embodied emotions is an excellent example for dynamic changes between transparency and opacity: You can "directly perceive" that your wife is cheating you, or you can become aware of the possibility that maybe it is you who has a problem, that your "immediate" emotional representation of social reality might actually be a misrepresentation.

As a first-order approximation, I would say that phenomenality is "availability for introspective attention": Consciousness is a property of all those mental contents to which you can in principle direct your attention.

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

As modern-day neuroscience tells us, we are never in touch with the present, because neural information-processing itself takes time. Signals take time to travel from your sensory organs along the multiple neuronal pathways in your body to your brain, and they take time to be processed and transformed into objects, scenes, and complex situations. So, strictly speaking, what you are experiencing as the present moment is actually the past.

I think that there is an ongoing conspiracy in the philosophical community, an organized form of self-deception, as in a cult, to simply all together pretend that we knew what "first-person perspective" (or "quale" or "consciousness") means, so that we can keep our traditional debates running on forever.
