h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

i have only just read this imformation at http://www.thekeyboard.org.uk/What%20is%20reality read throught that then we can have a debate about it.

it has a lot of points in it, which make you think, how do we know what i see is the same as what you see, but we wouldnt know otherwise because we have been brought up to name certain things by how they look, so if it was differnt for everyone it wouldnt matter because the word would hold its individual meaning but also an international meaning.

Say for instance i see a house as a house, a tree as a tree, a computer as a computer and a tv as a tv. but if i were to look through your eyes i would see a house as a tree, a tree as a computer, a computer as a tv and a tv as house, but you wont realize that we see them diferntly because it is the word you have always matched that image with.

It can be simpler than that! What about simple colors?
If you and I were able to exchange neural pathways, we may find that what looks "blue" to me, looks orange to you even though you call the color "blue", too.

Warm, cool, smooth, and rough, may also be reversed in some way, where we have the same physiological reaction, but interpret the sensations differently.

this would certainly explain things like why time goes faster for someone having fun compared to someone bored, and also why some people find people who i think are ugly, beautiful
