(Wydawnictwo Naukowe UAM, 2001) Pachocińska, Elżbieta
The trutstworthy speaker (interlocutor) presents his reasoning as based on logical deduction, although it is
structured by much more complicated relations.This is because of the goal posed before the discourse in
which an opinion is expressed. He tries to influence a recipient and to make him adopt a new point of view
which is not based merely on logical values. To achieve this goal the speaker (interlocutor) uses
argumentative structures which use procedures of natural reasoning.
