Discourse is not just a message meant to be deciphered, it is also a product that we make available to others and whose value is defined in relation to other products, whether rare or common. The effect of the linguistic market, which is materialized in shyness or stage fright when speaking in public, is manifested in the most trivial exchanges of everyday life: take as an example the language changes that, in bilingual situations, without even thinking about it , the announcers operate according to the social characteristics of their interlocutor. In addition to being an instrument of communication, the language is also an external sign of wealth and an instrument of power. Social science must try to justify what, well thought out, is still an act of magic: you can act with words, orders or slogans. Does the force displayed by the words come from the words themselves or from their spokesmen? Thus, we are faced with what the scholastics called the mystery of the ministry, a miracle of the transubstantiation that covers the word of the spokesman of a superior force, which is granted by the group in which he exercises it. By thinking about language from another point of view, we can approach the field par excellence of symbolic power, that of politics, the place of foresight as a prediction that aims to produce its own realization. And understand, in its specific economy, the regionalist or nationalist debate, apparently far from economic rationality. But we can also reveal the repressed intention of some philosophical texts, whose apparent rigor is nothing more than the visible trace of the especially rigorous censorship of the market to which they are destined.
