In his attempt to synthesize the differences between the Similarity Theory and the Convention Theory, Plato points out that even though language is conventional to a certain extent, there is still a union between the Word and the Reality which is by no means accidental. Language is instrumental and composed by human “name-makers” according to certain fixed laws. Language deals with the expression of truth and falsity at various degrees and at different levels. Plato’s thesis of knowledge, as well as that of the tripartite division of language, meaning, and the thing signified, has had a profound influence on the philosophers of language in subsequent generations.
