THE SUPERSUBSTANTIVALIST RESPONSE TO THE ARGUMENT FROM VAGUENESS by Mark Puestohl A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts in Philosophy at The University of Wisconsin-Milwaukee May 2013 ABSTRACT THE SUPERSUBSTANTIVALIST RESPONSE TO THE ARGUMENT FROM VAGUENESS by Mark Puestohl The University of Wisconsin-Milwaukee, 2013 Under the Supervision of Professor Joshua Spencer Unrestricted Composition is the axiom of classical extensional mereology according to which any objects, the xs, compose some y. Perhaps the most powerful argument for Unrestricted Composition is the Argument from Vagueness, which purports to secure Unrestricted Composition on the grounds of a few plausible theses about composition, vagueness, and the number of objects. Here I present Theodore Sider’s (2001) formulation of the Argument from Vagueness. I show that given supersubstantivalism— the thesis that material objects are identical to spacetime regions—we are in a position to consider the Argument from Vagueness unsound.
