Abstract

In this essay, we explore a fresh avenue into mind-body dualism by considering a seemingly distant question posed by Frege: "Why is it absurd to suppose that Julius Caesar is a number?". The essay falls into three main parts. In the first, through an exploration of Frege’s Julius Caesar problem, we attempt to expose two maxims applicable to the mind-body problem. In the second part, we draw on those maxims in arguing that “full blown dualism” is preferable to more modest, property-theoretic, versions. Finally, in the third part we close by suggesting that full blown dualism need not be spooky, resurrecting a broadly Lockean, rather than Cartesian, metaphysical picture.
