Abstract
The work starts from the idea that the natural instrument of communication in a class is constituted by linguistic propositions, called fuzzy propositions, which are grammatically and syntactically correct statements, but which often can not be classified either completely true or completely false. The truth value of a linguistic proposition depends on the opinions of a decision maker that are conditioned by the circumstances that occur. In this order of ideas the linguistic proposition is called a fuzzy event. A problem of decisions under conditions of uncertainty can be seen as attributing truth values to fuzzy events for each of the states of nature. Using the classic logical operations on events we can define the logical reasoning methods. We consider also an extension to fuzzy events, highlighting the fact that this leads to having to make choices of a subjective nature, on which to open interesting debates in the classroom.
