MENTAL FICTIONALISM As AN UNDERMOTIVATED THEORY.

Our paper consists of three parts. In the first part we explain the concept of mental fictionalism. In the second part, we present the various versions of fictionalism and their main sources of motivation. We do this because in the third part we argue that mental fictionalism, as opposed to other versions of fictionalism, is a highly undermotivated theory. [ABSTRACT FROM AUTHOR]
