The contradictory verbal exchange is primarily an exchange of positions determined by successive turn-taking, thus included in the interactive devise as it was initially comprehended, that is why the opponents’ representations always work alternatively and conversely. As a result involvement in a dispute requires reciprocal acknowledgement of the other as a true opponent, more precisely, his representation of the two positions that he would find himself in successively during the dispute. When talking the initiator has to identify with the defender and yet to imagine himself as the future opponent of what he is to receive in a future dispute, such as the proposals of the new initiator. This is the case with two important scientists of Romanian linguistics: A Philippide, and respectively, Bogdan Petriceicu Hasdeu.
