Each of our five senses are limited. Other animals can sense things that we cannot. We can construct devices that we employ to explore the world beyond our what our physical limitations can render. Nevertheless, there are still "things" out there that we will never be aware of.
So, that leaves us us, necessarily, with an incomplete idea of what reality really is.
In our everyday lives, we sense things around and within us. To us this is reality; and we operate within that concept as maintained within our minds. For the most part, that suffices to meet our normal needs. So, apart from the current computer-based notion of "virtual reality," we would seem to be constantly operating within our own human-based virtual reality.
Do we need a new vocabulary to describe these notions? A new vocabulary that is useful?
