Philosophy of Language and Interest

With the Philosophy of Language defined as 'the study of effective Communication', and the radical alterity of interpersonal relations accepted as a fundamental premise, the primary problem of the enterprise is to determine Commonality in Communication.  Three prominent solutions to that problem have been: 1. The metaphysical world (Leibniz); 2. The natural world (Russell), and 3. Cognitive structures (early Wittgenstein).  Accordingly, the later Wittgenstein can be understood as rejecting the shared assumption of all three, i. e. that Commonality is Monistic.  But, in the process of demonstrating the Pluralism of Language-Games, he, perhaps unwittingly, implies the possibility of a Monistic #4--Interest.  For, the source of Commonality in a Language-Game is the Purpose that unites it and its participants.  So, if there is a universal Interest, e. g. world peace, then it is a potential single ground of effective Communication.
