The aim of the paper is twofold. First, it expounds the thesis of ‘conceptual relativity’ propounded in a series of writings of the well-known philosopher Hilary Putnam and indicates the alleged manner in which the thesis, according to Putnam, undermines the foundations of metaphysical realism (understood in a peculiar way spelled out in the paper). Second, a critical examination of Putnam’s anti-metaphysical-realist argument is offered. It is argued that Putnam offers examples only of a trivial, so-called indexical relativity, and that his strategy leaves the foundations of metaphysical realism intact.
