 The force of this objection rests on the first problem of pragmatic principles raised above. For if that problem is solved, then the solution to the problems of psychological explanation, predication, and rationalization will follow on its wings. Insofar as utterances of (1) and (4) implicate different information about the way in which Lois believes what she allegedly believes, it seems likely that there will be a very natural account of the difference in their explanatory, predictive, and rationalizing potential, the difference in what is pragmatically implicated will account for the differences noted in this section. So the more fundamental problem facing the Naive Russellian is the problem of pragmatic principles.
