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 believe that gut feelings, the sense of balance, and spatial self-perception are so firmly coupled to our biological body that we will never be able to leave it experientially on a permanent basis.

Conscious experience as such is an exclusively internal affair: Once all functional properties of your brain are fixed, the character of subjective experience is determined as well.

The notion of a conscious model of oneself as an individual entity actively trying to establish epistemic relations to the world and to oneself, I think, comes very close to what we traditionally mean by notions like "subjectivity".

Speaking as a phenomenologist, it seems to me that a considerable portion of mind wandering actually is "mental avoidance behaviour", an attempt to cope with adverse internal stimuli or to protect oneself from a deeper processing of information that threatens self-esteem.

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

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