E Pluribus Putnams Unum: Hilary Putnam and the Indispensability Argument

In this paper, I argue that the indispensability argument unifies all of Hilary Putnam’s diverse work in the philosophy of mathematics. I also argue that his version of the indispensability argument does not justify knowledge of mathematical objects. I first characterize indispensability arguments in the philosophy of mathematics, distilling them to four essential characteristics. I show that t...

On Putnam

Hilary Putnam has made major contributions to philosophy of mind and philosophy of language. In philosophy of mind, he developed the theories of multiple instantiability and functionalism. In philosophy of language, a major contribution of his is semantic externalism. This paper will give a very brief overview of multiple instantiability and functionalism, and then describe semantic externalism...

My Putnam Problems

4. (A1 or B1 problem) Let C be a circle of radius 1, and let D be a diameter of C. Let P be the set of all points inside or on C such that p is closer to D than it is to the circumference of C. Find a rational number r such that the area of P is r. 5. Let n be a positive integer, let 0 ≤ j < n, and let fn(j) be the number of subsets S of the set {0, 1, . . . , n−1} such that the sum of the elem...

Putnam and Constructibility *

I discuss and try to evaluate the argument about constructible sets made by Putnam in “Models and Reality”, and some of the counterarguments directed against it in the literature. I shall conclude that Putnam’s argument, while correct in substance, nevertheless has no direct bearing on the philosophical question of unintended models of set theory. MSC2000: 00A30, 03A05, 03E45.
