Abstract

The studies on the history of logic in the Polish schools of the Commission for National Education in the period of the Enlightenment that have been published up to date evaluate the educational practice with respect to its accordance to Condillac’s work. His textbook was indeed order by the Commission for its schools, and it was also evaluated highly, but it was not published in the Polish language. From the rules of the Commission and its didactic practice, which made use of a series of the most eminent eclectic textbooks on logic then functioning in the European school, we can deduce that the Commission must have evaluated Condillac’s book as too one-sided. Aside to his approach, there functioned in then Polish school a number of other studies. The Commission exposed a textbook written by the French Jesuit, Claude Buffier, in the first place. Despite the fact that he was close to modern solutions, e.g. Descartes’ and Locke’s, nevertheless he showed respect for scholastic tradition. Accordingly, he presented a group of solutions well-known from the traditional approaches. He only emphasised, in the modern spirit, how important is the veracity of the premises of syllogism as the fundamental condition for the veracity of the conclusion. It follows that the role of the theory of reasoning was limited and at the same time the value of epistemological problems was stressed
