Well actually, I don't exist - not yet, but that's another matter entirely.
I'm willing to concede - without knowing for certain, that you experience 'I' - and that Descartes experienced 'I' - but cannot concede that 'I' is an experience independent of, and therefore distinct from the physical body and physical world.
Therefore, logically, if the existence of the physical body and world can be doubted, such that existence itself does not stand as a rational and undeniable truth, then neither does 'I'.
By reverse, if 'I' exists then the phsical body and world exists and the plethora of rational truths we would ordinarily concede without knowing for certain fall within the scope of our reasoning.
So you're right, as Socrates, if he existed, said: i know that i know nothing.
