"I think, therefor I am"
Also, theirs no way of saying anyone shares concurrent reality. Remember that theory that right before you die, your life flashes before your eyes? Now, lets pretend for a moment, you completely live your life in that time. At the end, you'll replay your life...
Wake up, anon.

"And René Descartes was a drunken fart 'I drink therefore I am'"

[quote]"I think, therefor I am"[/quote] Nice phrase but it doesn't actually prove anything.
-
Well, it proves self existence (which was a genuine point of interest in the early Enlightenment). There's no way to prove it to another though, sadly.

[quote]Well, it proves self existence[/quote]No, it doesn't actually. You see, the 'I' that is apparently proven to exist at the end, is already there at the start. 'I think' already presupposes that I exist, so it cannot therefore be proof that I exist. How do i know i exist? Because I am thinking. But how do I know I am thinking? Because I exist. It's a classic example of circular logic. It's like saying the Bible is true because it is the word of God, and God exists because it says so in the Bible.

Circular logic can actually be applied to these circumstances though. How can you exist without the capability to do anything? Doing something proves the point of existence, as existing proves the point of being able to do something.

You're missing the point. You can't prove your existence if you have to assume you exist first; that just doesn't make sense as an argument. You can say that existence and 'doing things' go hand in hand and can't be separated, if you really want to, but you can't then prove one of them simply by inferring the other one. If something's existence is in doubt then so is whether it is 'doing things', because 'doing things' can only happen if the thing exists, which hasn't been proven yet.

It's all a cycle. No one ever really dies.
