  Another stumbling block, in the case of analytical behaviorism, is the fact that the behavioral sentences that are intended to offer the behavioral paraphrases of mental terms almost always use mental terms themselves (see Chisholm 1957). In the example of my belief that I have a 2pm dental appointment, one must also speak of my desire to arrive at 2pm, otherwise the behavior of arriving at 2pm could not count as believing that I have a 2pm appointment. The term “desire” is a mental term. Critics of analytical behaviorism have charged that we can never escape from using mental terms in the characterization of the meaning of mental terms. This suggests that mental discourse cannot be displaced by behavioral discourse. At least it cannot be displaced term-by-term. Perhaps analytical behaviorists need to paraphrase a whole swarm of mental terms at once so as to recognize the presumption that the attribution of any one such mental term presupposes the application of others (see Rey 1997, p. 154–5).
