 This is not how Putnam understands his idea of conceptual relativity, however, which thesis he distinguishes from conceptual relativism. As he sees things, we accept a theory which licenses us to assert “Electrons exist” and also licenses us to assert “if humans were to disappear from this planet, electrons need not follow in their train” since the theory assures us that the existence of electrons in no way causally depends on the existence of humans. For the anti-realist our well-founded practices of assertion ground at one and the same time our conception of the world and our conception of humanity’s place within it.
