In this paper, we would like to discuss Wittgenstein’s critique of the idea that a person’s experiences are necessarily private, and these experiences can only be expressible in a private language. Taking a clue from Wittgenstein, we intend to say that the person’s experiences though private, can also be known by others. In the following sections 243 of his Philosophical Investigations, Wittgenstein argues against the possibility of a private language about the subject’s inner experiences. He contends that by coining names/words (...) to name sensations and our inner experiences, we cannot create a private language. If we have a list of names, that cannot function as a language. We need predicate terms; we need the syntax to link the words in the form of a sentence. If we use private names and use the predicates from the language that everyone knows, then the private words will acquire public status like the terms ‘pain’ and ‘sensation.’ These terms are already part of the public language, and if private experiences like pain and sensation cannot be made public, we would not have these terms in our language at all. This is the reason why any application of words is public, and therefore, there is no possibility of a private language. Wittgenstein concentrates on the public rules that govern the correct application for the use of words. And the expressions are meaningful only when these are used according to rules of grammar; if these expressions do not follow any rules of grammar, these are simply meaningless. (shrink)

In his last papers about deontic logic, von Wright sustained that there is no genuine logic of norms. We argue in this paper that this striking statement by the father of deontic logic should not be understood as a death sentence to the subject. Rather, it indicates a profound change in von Wright's understanding about the epistemic and ontological role of logic in the field of norms. Instead of a logical constructivism of deontic systems revealing a necessary structure of prescriptive (...) discourse, which marked his earlier efforts, he adopted the view that such systems should be seem as mere objects of comparison, i.e. as providing practical standards of rationality for normgiving activity. Within such view he proposed an interpretation of standard deontic logic in such a way to free deontic logicians from the philosophical difficulties related to the so-called Jørgensen's dilemma and deontic paradoxes. This effort, as we claim in the present paper, is an application of Wittgenstein's therapeutic method to dissolve philosophical difficulties caused by the use of logical tools to model relations between norms.
