The Kyiv-Mohyla Academy (KMA) was founded by Metropolitan Petro Mohyla (Petru Movilă) in 1632. As the first Orthodox institution of higher education in Ukraine, it played an important role in the country’s cultural development for two centuries. The Academy also played a significant part in the development of academic philosophy in Ukraine. Thanks to the large number of well-preserved manuscripts, it is possible to study the dominant philosophical trends at the KMA during different periods. A study of the available material showed that the philosophy professors at the KMA were influenced by Western authors, predominantly Catholic ones. The most interesting aspect is how the Orthodox professors accepted the ideas of Catholic authors and whether they modified them.
