Inferential role/Brandom: Without them it is not clear why what is represented by an atomic sentence or a simple predicate should be important for what is represented by another one - e.g. non-inferential: Indicating: cannot form an independent field of language.
Content/Dummett/Brandom: conceptual content as inferential role: 1) circumstances: (sets of premises) - 2) consequences: (narrowing of consequences).
Empirical concepts: rather non-inferential - circumstances: also beliefs, actions, perceptions.
