When Does Communication Succeed?
Concepts associated with general terms vary substantially between speakers, even between speakers of the same language. There can be differences even about topics as basic as whether the hand is part of the arm, i.e. about the meaning of ‘arm’. Still, such differences are rarely detected in normal communication. Two questions arise. The first is whether communication fails in the case of interpersonal conceptual differences, or whether there are differences that, depending on the relevant requirements of the context, don’t matter, so that communication (in some cases) succeeds despite the variation. To answer this, we need a model of communicative success. The second question is why even such basic differences as in the example typically fail to come to light. What mechanism of communication allows it to flow smoothly despite the variation? This chapter attempts to answer both these questions.
