Scholarly literature overwhelmingly shows that Wittgenstein's remarks on doubt and certainty in On Certainty were developed in direct opposition to, rather than as a continuation of, Cartesian epistemology.
The retrieved papers consistently treat Wittgenstein's views on doubt (such as those in On Certainty) as a critique, refutation, or alternative to Cartesian skepticism rather than a direct derivation from Descartes. There are no papers supporting the idea that Wittgenstein's maxim originated directly from Descartes; instead, they position him as anti-Cartesian or as offering a radical departure from Cartesian foundationalism.
