I have been reading some descartes, and I find myself agreeing with him, to the point of the idea as being able to base our belief in self on the fact that we are thinking.
My problem is that we cannot be sure that our thoughts are not simply prewritten recordings, or being projected. Of course, there is the argument that there is no evidence that those things are occuring, either. I guess therein lies the crux of things. We have no proof of anything, really, not even a first assumption, therefore we do and do not exist, depending on what hallucination you ascribe to.
