Abstract

In this paper I present, analyse, criticise and expand on the concept of interpretational invariants created by Michael Heller. I argue that Heller in fact holds two separate views of interpretational invariants and that in the context of his writings they should be, in fact, hold jointly. I propose a critique of one of those views, that in which one claims that there exist interpretational invariants across different mathematical representations of a theory. This leads me to propose a modified version of interpretational invariants, which are relativised, but not reduced, to mathematical formulations of a certain theory.
