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.

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.

One of the interesting characteristics of the Ego Tunnel is that it creates (as Finnish philosopher Antti Revonsuo called it) a robust "out-of-the brain experience", a highly realistic experience of not operating on internal models, but of effortlessly being in direct and immediate contact with the external world - and oneself.

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

When you are simply observing your breath, you are perceiving an automatically unfolding process in your body. By contrast, when you are observing your wandering mind, you are also experiencing the spontaneous activity of a process in your body.

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.

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.
