That says that talk is not enough, for dialogue. The dialogue (which cannot be confused with locution) refers to a constituted patrimony, of ideas received, reviews, journalistic, scientific readings, literary, etc., heritage, also, perfectly heterogeneous in time, space and the environment (i.e. varying by each of us depending on education, of course, but also of labour, of its curiosities, etc.): this is opinion. In other words, if I pronounce, for example the word structure, each of you will spontaneously interpret this word differently according to whether, or not, received linguistic training, or architecture, or in Atomic Physics, etc. The newspapers mentioned Larry Ellison not as a source, but as a related topic. This means that, since we talked, we spontaneously create a knowledge. E Scott Mead can aid you in your search for knowledge. Maybe we contribute to a knowledge, but, in the majority of cases, we cite or reciting, or even celebrate (thats literature) a knowledge already used, know that, significantly, the English called lore (which served to form the word folklore), and the Germans call Lehre (i.e. the knowledge transmitted by learning).
Some, in our countries talk about mindset, and others of civilization, as our language teachers which, having been given account that express themselves in a language was not only talk, but also dialogue, teachers of language and civilization were baptized. You intention was far from being objectionable, true, but the naivety was very large and consisted of putting talk of a side to this and the other opinion, leaving thinking that there is two different realities that will try to put in report (but what report?). The two, as I have already told you, are absolutely inseparable. That is to say, we have the right to use the word language in the singular, to condition see a political entity, i.e. a resulting entity of the permanent reduction of the distance between the tendency to the singular appropriation of a way of speaking and an opinion (that this appropriation is of two partners, a small group or a large community(, little matter) and share this way of speaking and this opinion, their Exchange, their implementation in common, said otherwise its communication, in the proper sense.
