By separating, within the Cogito, on the one hand, hyperbole (which I maintain cannot be enclosed in a factual and determined historical structure, for it is the project of exceeding every finite and determined totality), and, on the other hand, that in Descartes's philosophy (or in the philosophy supporting the Augustinian Cogito or the Husserlian Cogito as well) which belongs to a factual historical structure, I am not proposing the separation of the wheat from the tares in every philosophy in the name of some philosophia perennis.
