*sigh* Ahhh... philosophical debate. There's not much that I ... well... the word isn't enjoy, or hate. I am filled with loathing for some of the asinine thoughts I have heard uttered from the mouths of people I know, yet for some reason I can't help but argue about it instead of just saying, "That is utterly idiotic, and I find it repugnant that you would assault my ears with such tripe."
And... in that vein... look at yourself as a symbiotic being. You have your brain or mind, and then you have your body, with little nervy tendrils snaking throughout in order to get information. Now your view of the world; sight, smell, taste, sense of direction, etc are all interpreted from the various sensory organs of the body by the brain. Your perception of what's around is, in a very real way, a simulation created by the brain, in the brain and for the brain.
Oh, and in terms of having to have all the information stored, not so. There are ways to cheat that. Algorithms in programming do a wonderful job of it. Hell... an MP3 with a high enough sample rate is indistinguishable from live music. It doesn't change the fact that the MP3 is an imperfect representation of the actual sound.
My advice on the whole thing? Leave philosophy to those who have managed to con their way out of having real jobs and get paid by the government to think their deep thoughts in our colleges and universities. Unless, of course, you want to con the government, too.
Edit: Oh! I almost forgot. Hippies also get to wax philosophical, they just don't have to pretend that any intelligence drives what they're saying.
