This paper investigates the development of dialectical concepts about the universe, being, metaphysics, scientific methods, and the knowledge of philosophers. The methods it uses are mainly theoretical and empirical methods, such as analysis and synthesis. Within the boundaries of the designated topic, it offers a systematic analysis of the historical periodization of Arab Muslim philosophy from the eighth century to the twentieth. The paper examines the activities of the prominent philosopher and mathematician Abu Nasr Muhammad ibn Muhammad al-Farabi, showing the (...) circumstances of his borrowing certain forms, concepts, and structures from ancient Greek philosophers. The paper's main conclusion is that al-Farabi is a Second Teacher in modern philosophy, meaning the continuation in his works of the search for a scientific approach to the study of various forms of being.
