 In spite of these structural analogies, we may still wonder why an elucidation of the notion of force is important for a theory of communication. That A is an important component of communication, and that A underdetermines B, do not justify the conclusion that B is an important component of communication. Content also underdetermines the decibel level at which we speak but this fact does not justify adding decibel level to our repertoire of core concepts for pragmatics or the philosophy of language. Why should force be thought any more worthy of admission to this set of core concepts than decibel level? One reason for an asymmetry in our treatment of force and decibel level is that the former, but not the latter, seems to be a component of speaker meaning: Force is a feature not of what is said but of how what is said is meant; decibel level, by contrast, is a feature at most of the way in which something is said. This point is developed in Section 5 below.
