several passages

Ludwig Wittgenstein wrote several passages about the incompleteness theorems that were published posthumously in Über formal unentscheidbare Sätze der Principia Mathematica's 1953 Remarks on the Foundations of Mathematics.

Wittgenstein

Wittgenstein is best known for Wittgenstein's spectacular incompleteness theorems, and Wittgenstein's Platonist orientation toward mathematics.

repudiation

Ludwig Wittgenstein's Remarks on the Foundations of Mathematics contains Ludwig Wittgenstein's compiled views, notably a controversial repudiation of Gödel's incompleteness theorems.

, quite amazingly primitive”

In a footnote Principia Mathematica says that Wittgenstein’s comments in Principia Mathematica's Remarks on the Foundation of Mathematics on Gödel’s Incompleteness Theorem “appear at first sight, to one trained in mathematical logic, quite amazingly primitive”: strong words from a discreet writer.

Floyd & Putnam and Steiner 2001 (2000) ()

Recently, and perhaps most interestingly, Floyd & Putnam (2000) and Steiner (2001) have evoked new and interesting discussions of Wittgenstein’s ruminations on undecidability, mathematical truth, and Gödel’s First Incompleteness Theorem (Rodych 2003, 2006; Bays 2004; Sayward 2005; and Floyd & Putnam 2006).
