Representationalism in measurement theory – Structuralism or Perspectivism?

In Chapter 6, Johanna E. Wolff uses models of measurements as a case for exploring two forms of scientific realism that are meant to address the problem of plurality of models in science: structural realism and perspectival realism. She distinguishes their motivations in the following way: structural realists address the plurality of models by looking for similarities, namely structural commonalities, between the models, whereas perspectival realists emphasize how differences among a plurality of models can be complementary. In comparing these realist alternatives, Wolff chooses to focus on measurement theory. Wolff urges the idea that perspectival realism and structural realism are not competing realist accounts but complementary ones.
