(10[2])This argument was made in a 1939 paper (10[1])that follows up (10[1])on the author’s “Defense of Common Sense.” (10[5])For 10 points, identify this argument purporting to refute skepticism (10[1]-5[1])that G. E. Moore (10[1])made (10[1])with (10[1])two of his body parts. (10[2])■END■ (10[3]0[5])
