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

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.

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.

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

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

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.
