|It is natural that every person in his everyday life faces differences of opinion in contact with other people, this can happen in all spheres of life: in family life, at work, in public life. These differences of opinion can emerge as a result of a dramatic event or, on the contrary on the very simple issues. One can express the opposite opinion verbally, during the conversation directly, which is very frequent, and in written form, as well. In such cases he advances argumentation to defend his or her standpoint, and this is done in order to resolve the emerged debate. This kind of discussion is named argumentative discussion. In everyday usage, argumentation often has negative connotations, suggesting quarrelsomeness and unpleasantness. Though it is reasonable to put this stereotype aside and examine argumentation in its classical sense—as the study of effective reasoning. Argumentation relates to the field of rhetoric. Rhetoric is another term that has taken on pejorative connotations but that has a rich history as the study of how messages influence people. Argumentation is also related to two other fields, logic and dialectic, concerning which were written very deep and precise works by E.Rigotti, Frans van Eemeren and many others.
