What's it like to be? How do I know that I am?
Do I exist independently of the Universe and all of you? Or would I cease in the absense of the perception of those around me? Would I become the sound the tree may or may not make when it falls and noone witnesses?
But, if there are other trees around, are they not witnesses? Is counciousness and self-realization a requisite of being? If so, do stars and germs and trees and photons not exist? What does exist? If nobody perceives which side of the coin is up when flipped in a blackened room, does that really mean that neither side is truely "up"?
What should I have for lunch today?
