the article presents a brief overview of the study of classical Islamic philosophy in chronological order. According to the author, in Western countries, the scientific research of Islamic philosophy began within the framework of the Christian scholastic tradition, yet later the analysis of Arabic texts as well as the structure of Islamic theoretical thought was initiated. Some scholars applied a methodological approach to the study of Islamic philosophy. Orientalist philologists also played an important role in the study of the religious and philosophical doctrine of Islam. Both of these schools adopted a methodological approach based on the traditions of Christian and Jewish philosophy and theology, which in some aspects had similarities with Islamic thought.
