The article shows that the Aristotelic tradition dominated the philosophical courses of
Kyiv-Mohyla Academy in the 17th and 18th centuries. It puts forward several arguments.
First, the professors of the Academy called their philosophy Aristotelian, Peripatetic or ad
mentem Aristotelis. The analysis of the titles of the courses reveals that since 1639 until
1751, when scholastic-type courses were taught, the Mohylanian professors never had
shown allegiance to any other philosopher, but Aristotle. Second, the courses of logic and
physics (the largest parts of the philosophical course) were structured around Aristotle’s
books: Cathegories, De interpretatione, Prior Analytics, and Posterior Analytics; and Physics,
De Caelo, De Ge neratione et Corruptione, De Meteoris, and De Anima, respectively.
Third, the main concepts used by the professors come from Aristotle. However, Aristotelian
tradition, which is evident in the courses, most likely does not come directly from reading
of Aristotle’s texts, but from scholastic textbooks of the 17th-18th centuries. Kyiv-Mohyla
courses were especially influenced by Jesuits. The Jesuits, unlike most Catholic orders of
that time, also called their philosophy Aristotelian. Teaching philosophy ad mentem
Aristotelis was instructed by regulative documents of the Society of Jesus, like Constitutiones
and Ratio Studiorum. Nevertheless, there are cases in the Mohylanian courses when the
professors had greater familiarity with Aristotle’s texts. For example, Theophan Prokopovych
gives a detailed account of Aristotle’s books Cathegories and De interpretatione. It is possible
to conclude that the Kyiv-Mohyla philosophical courses represented the Aristotelian
tradition, but the level of familiarity with Aristotle’s texts depends on the professor.
