Universal Language and Communication

Modern Philosophy of Language begins not with Frege and Russell, but two centuries earlier, with Leibniz' efforts to develop a "Universal Characteristic", i. e. a universal language, in the course of which he also pioneers Symbolic Logic, and the cross-breeding of Logic and Mathematics.  Now, as he explains in the 1677 piece 'Towards a Universal Characteristic', by means of a "universal language", it becomes "possible for people of different nations to communicate their thoughts to one another".  Implicit in that thesis is a two-fold criticism of Russell's attempt to isolate Language from Communication, i. e. his 'Propositional Attitudes' from Propositions--1. The mistaking of 'impersonal' as 'non-personal', rather than as 'universally personal'; and 2. The lack of recognition of the possibility of universal motives, e. g. the desire to communicate.  Derived from Leibniz, that challenge to Fregean-Russellian Philosophy of Language cannot be as easily dismissed as 'misologistic' as some practitioners of that technique seem to assume.
