 His three theses in the philosophy of language undergird his whole theory of interpretation and entail certain parts of the answer to the question just raised. It is an implication of his thesis that all thought is essentially dependent on and bounded by language that an interpreted subject’s language is in a certain sense bound to be a reliable indicator of the nature of his thought, so that the interpreter at least need not worry that the interpreted subject might be entertaining ineffable thoughts or thoughts whose character is systematically distorted by his expression of them in language. It is an implication of Herder’s thesis that meaning consists in word-usage that interpretation essentially and fundamentally requires pinning down an interpreted subject’s word-usages, and thereby his meanings. Finally, it is an implication of Herder’s quasi-empiricist thesis concerning concepts that an interpreter’s understanding of an interpreted subject’s concepts must include some sort of recapturing of their basis in the interpreted subject’s sensations.
