摘要:AbstractOur study focuses on the problems of private language, or, as approached in the philosophical exegesis as “the argument of private language”, described as such in Ludwig Wittgenstein's late writings. Our goal is that, through a textual analysis and interpretation, to link the philosopher's slightly framed idea on expressions to the field of general human communication, focussing on the way we learn, from a little age, psychological concepts. As in the case of sensations and in that of primary emotions, that a have a specific behaviour, respectively universal facial expressions, we consider that the non verbal elements are both the model and basis on which verbal communication is constructed.
