Spinoza on Language

Some scholars have understood that Spinoza’s extreme rationalism, nominalism, conventionalism, and rejection of a semantic theory of truth make his philosophy incapable to use language for philosophical and scientific purposes; insofar he considered language a source of inadequate knowledge, falsity, and error. Thus Spinoza finds contradiction in his inevitable use of language to express his philosophy. This paper has four aims: first, propose an explanation on why language is inadequate knowledge for Spinoza; second, present differences between inadequacy, falsity, and error in language; third, argue on the Spinozian use of the geometrical method as a solution for the adequate use of language in philosophical and scientific work; finally, show the problems and limits of this solution for metaphysical discussions.
