"Piąta droga" św. Tomasza z Akwinu w formalizacjach J.M. Bocheńskiego i P. Weingartnera
St. Thomas Aquinas' "Fifth Way" in J.M. Bochenski's and P. Weingartner's Formalizations

Summary/Abstract: The present state of research reveals that basically Fr. J.M. Bochenski (1902-1995) left three versions of the formalizations of St. Thomas Aquinas’ fifth way. The first version comes from the article “Die fünf Wege”, published in 1989, and the third one, which is unauthorized, from the book “Gottes Dasein und Wesen. Logische Studien zur Summa Theologiae I, qq. 2-11”, published in Munich in 2003. These works are completed by the second version from two manuscripts of the book: one German (1989) and one Polish (1993). The above mentioned texts have shown the contribution made by Fr. J.M. Bochenski into the realization of the intended application of the tools of contemporary logic in the field of philosophy of God as well as theology. One of the main followers of these ideas in Austria has been Paul Weingartner (born 1931). In 2010 he published “God’s Existence? A Logical Commentary on the Five Ways of Thomas Aquina”s, a book which makes direct references to J.M. Bochenski’s works, and like Bochenski’s work it is a logical commentary to certain fragments of St. Thomas Aquinas’ “Summa Theologiae”.
