Description acceptable. A book written in response to this argument inspired Annalisa Coliva’s work on hinge epistemology by treating one of this argument’s premises as a “hinge proposition.” The weakness of this argument was identified as “transmission failure” by Crispin Wright. A class of arguments against moral error theory repurposes this argument’s procedure of replacing the opponent’s modus ponens with a modus tollens, which is called its creator’s namesake “shift.” At the behest of Norman Malcolm, Wittgenstein spent the last two years of his life compiling notes on this argument that became the book On Certainty. This argument was made in a 1939 paper that follows up on the author’s “Defense of Common Sense.” For 10 points, identify this argument purporting to refute skepticism that G. E. Moore made with two of his body parts. ■END■
