Theoretical representations in discussions surrounding the semantic significance of words and their analogs in thought should not be viewed under a realist interpretation as individually revealing what the represented items really are. Instead, they should be viewed under an instrumentalist interpretation as having other roles to play within their respective explanatory contexts. I consider some case studies for this broad methodological claim: theoretical representations of the semantic significance of words within semantics, theoretical representations of what determines the semantic significance of (...) words within metasemantics – both under the auspices of the so-called new theory of reference – and theoretical representations of cognitive attitudes within the Representational Theory of Mind.
