(It is an English version of article contained in this volume of the journal, pp. 223–229). This article discusses the biography, works and philosophical views of Giuseppe Angiolini, an Italian Jesuit working at the Academy of Polotsk at the turn of the 18th and 19th centuries. The whole philosophy represented by Angiolini is in line with Italian Catholic philosophy, which in turn was influenced by the traditional Jesuit Collegium Romanum. The philosophy of Angiolini contains certain Suarezian ideas. In this respect it was influenced by the Jesuit tradition, especially as regards the mental difference between essence and existence, and modalism.
