However, If we do live in a matrix, then wether all this is real or not is real to us and effects our assumed lives. So really we dont know. I cant tell you weather i agrre with his theory or not, im stil skeptical, but i like it anyway.
But taking this philosophers side... If we were in a dream, perhaps you are a female dreaming your a male. If you kicked a rock, then maybe you really did kick a rock or it is in the mind, that imagines life. I see your point, in fact it has made me think, but Discartes thought that concept, that he knows he exists because hes able to think about it. He doesnt know the rock exists, or anyone else exists, because he doesn't know if they think. He is not them. We can only assume that thy think becasue of science and common sense, but whos to decide science is real?
If a female dreams she is a male, that no more makes her a male than her dreaming she is riding an elephant means that she is riding an elephant. To dream you are doing X does not imply that you are doing X, and to dream that you are Y does not imply that you are Y.
I know that I exist because I could not wonder whether I exist without existing. So, if I do anything at all, I must exist to do it.
As I pointed out, a rock doesn't have to think for it to exist. Who would believe such a thing. Descartes never said that if you exist then you think. He said if you think then you exist. It does not follow that because a rock exists it thinks. But it would follow that if a rock thought, then it would exist. You have to distinguish between: If X thinks, then X exists. Which is true, from, if X exists, then X thinks, which is, of course, false. As in the case of the rock.
That I might be living in a matrix does now mean that I don't know I am not living in a matrix. That a horse might be a female does not mean I do not know the horse is a male. If I told a person that I own a male horse, and he said, "well, it might be a male horse, but you don't know it is, since it might be a female horse" I would just stare at him. What could he mean?
