Sabe-se que Wittgenstein não recebeu bem os resultados de Goedel. Mas, sua crítica foi depois muito rebatida. Francesco Berto, todavia, no artigo cujo resumo está a seguir, argumenta que Wittgenstein propositalmente recusava a distinção entre o nível objeto e o meta-nível e ao mesmo tempo tinha intuições que hoje conferem com propostas de uma aritmética dita paraconsistente.

“The Gödel Paradox and Wittgenstein's Reasons - Philosophia Mathematica
By Francesco Berto
“An interpretation of Wittgenstein’s much criticized remarks on Gödel’s First Incompleteness Theorem is provided in the light of paraconsistent arithmetic: in taking Gödel’s proof as a paradoxical derivation, Wittgenstein was drawing the consequences of his deliberate rejection of the standard distinction between theory and metatheory. The reasoning behind the proof of the truth of the Gödel sentence is then performed within the formal system itself, which turns out to be inconsistent. It is shown that the features of paraconsistent arithmetics match with some intuitions underlying Wittgenstein’s philosophy of mathematics, such as its strict finitism and the insistence on the decidability of any mathematical question.
