But I think that Descartes would regard his own process as inadequate, which evidently he did not, if he saw himself as taking as his first principle/assumption the idea that he could doubt everything. Conversely, it is always possible to infer background assumptions from non-gibberish (at least under some allowance for presuppositional inference, as in Kant's transcendental arguments), but that is pointless if the point is not to presuppose them. Cogito ergo sum is intended to find an essential truth relating the metaphysical and the empirical realm. This is before logic has been applied.
