Abstract
Language is nothing but human subjects in as much as they speak, say and know. Language is something coming from the inside of the speaking subject manifest in the meaningful intentional purpose of the individual speaker. A language, on
the contrary, is something coming from the outside, from the speech community, something offered to the speaking subject from the tradition in the technique of speaking. The speech act is nothing but the development of an intuition by the subject thus transforming it in words of a language. It is both individual and social. Since human subjects are free and historical, the study of speech acts is hermeneutics, that is, interpreting speech acts with knowing and the human reality
