ABSTRACT:
Hilary Putnam sought to undermine cognitive relativism by charging it with self- destructive incoherence. Thomas Kuhn's conception of the development of scientific knowledge occupies a prominent place in that critical endeavor, and the incommensurability between rival paradigms constitutes the core of the dispute. Putnam claimed that incommensurability is self- refuting, taking into account only its semantic dimension. This article examines this anti-relativist attack. I consider two senses of self-refutation, the material and the formal, and argue that they do not affect the semantic formulation of incommensurability. Additionally, I show that the epistemological dimension of incommensurability is also unaffected.
