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.
Thomas MetzingerVirtual reality is the representation of possible worlds and possible selves, with the aim of making them appear as real as possible - ideally, by creating a subjective sense of "presence" and full immersion in the user.
Thomas MetzingerI 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.
