If the world is your reality, then yes i do not exist. However, you do not have the exclusive on this world so i would say that i do exist. If i did not exist how could i respond with such thoughts. The thing with Jesus is that you cannot be sure he existed. Did you ever meet him? Have you ever seen him? I haven't therfore i conclude that i cannot be sure he exists. Thnough a similiar thought process can be done for all things. for example... I know all crows are black, however, i have not seen all crows. Therfore how can i say that I know all crows are black???I believe that certain assumptions must be accepted in this world despite of knowing for sure. it makes the world run smoother to asusme such things. besides if we didn't have assumptions and assume they were true the world would reolve around us sitting down and doing philosophy all day. Though it would be fun for a while, i would tire of it soon.
Well... for one, denying your own existance is kind of shooting yourself in the food, becuse the denial itself is sufficient proof of existance (Descartes "I think, therefore I am..." add "...whether I like it or not." But that's about as far as we can really go for proof of any existance. Anything else we see, or think we see, could be a dream, a delusion, or a trick. So, Pkhosheta, even if you did meet Jesus (which many have done on peyote and such), or see all the crows in the world, you still would know anything for sure. The certain assumptions you are talking about boil down to faith. We all have it to a certain degree, whether we beleive in Jesus, even though we have never met him, or we believe that the chair we are sitting in actually exists. Unless, of course, you're a Nihilist (sp?), in which case the only thing you actually believe is that you're going to get a million dollars for Bunny Lebowski.
*I believe in theory what I know in practice to be true* -Aldus Huxley
Descartes has a big problem with his argument "Cogito ergo sum" (that's the only Latin i know) the problem being that, as you said, a chair exists if we believe it exists or not. If a chair doesn't think, does it exist still? Of course it does. Or it exists at some point or form of existence. There could be other planes of existence which we are not aware of. This group is really great. People who play poker, like philosophy and the Big Lebowski....I'm amazed. The only thing better would be if attractive young women flocked here. Anyway, we should be friends because of our mutual likes.
As for the jesus post, you believe that you cannot accept he is real because you have never met him what about X number of years down the road will your great grandkids (if you have any) deny your existance as a myth invented to give them a purpose? As for things being real, reality is what you make it for if you get down to the science every single thing you see with the human eye is an after image (light bounces off things then into the eye) so with that said how are you sure that things are really there, and really look how you view them? As for "I think therefore I am" that is assuming that what we do is thought, and what is existing?
I had to back Sethauj up - we can prove nothing more than our own existences. Everything else could be a figment of our imagination. Including this message.
