The present paper deals with the consequences Kripke?s interpretation of Wittgenstein?s private language argument has for political and social thought. We will show this is particularly important because it challenges the framework where ordinarily is located the discussion of the political and social relevance of Wittgenstein?s thought. Classical discussion has been concerned mainly with the role of communitary agreement, its relativistic or conservative consequences, the room for criticism and disagreement that it leaves, etc. We discern in classical reading a commitment with some epistemological problems (warrants for knowledge) which is not completely overcame, its semantic jargon notwithstanding. Instead, we will argue, the new framework proposed by Kripke, overcome this epistemological problematic, rising new concerns, close to which, in French contemporary thought, has been called ?philosophies of the subjection of the subject?.
