We think that the world is a solid, vivid place, full of shape and colour and solid objects like this table and this microphone and so on, but we actually create that in our heads out of the bits of information that hit the back of our eyeballs or hit our eardrums or hit our tongues or whatever.

What the computer in virtual reality enables us to do is to recalibrate ourselves so that we can start seeing those pieces of information that are invisible to us but have become important for us to understand.

Douglas Adams Quotes
