Semantic Externalism and the History of Ideas: A Critical Review

Abstract A recent innovation in the study of methods in the history of ideas is the introduction of elements of semantic externalism from the philosophy of language. Studies that rely on semantic externalism have done so to address particular questions of method in political theorising, including the interpretation of ‘essentially contested concepts’, and the issue of relativism in historical contextualism. In this paper, I critically review the use of semantic externalism, and associated methods such as Kripke’s causal theory of reference, in the history of ideas. I explore the barriers that might prevent the use of externalism, and how studies relying on externalism seek to overcome such barriers. I then assess both the implications of relying on externalism, as well as a set of limitations.
