C'è logica nel pensiero critico?

This paper gives an account of the experiment of a short series of lectures which was posited by the author at the beginning of the first year of the Degree of Education at the University of Salerno and whose content was the structure of argumentation and the rules of dialogue. If the series of lectures was appreciated by the students, the main difficulty concerned how to introduce and to discuss logic and its basical contents (propositional logic, categorical logic, modalities and so on) in the run of the lectures. The author attempts to show that this introduction is factually necessary even if it stays hard, proposing some ways in order to do that.
