Abstract

Abu Ali ibn Sina - Avicenna is one of the founders of medieval medicine. He is one of the great learned encyclopedias in the Muslim East. In the epistemological system of the sage, the main place is occupied by theory and experiment. The peculiarity of this theory lies in the interconnection of processes and an accurate interpretation of the essence of this world. In the epistemology of the scientist, the relationship between God, Nature, Soul and Mind is traced. According to Avicenna's idea, this is the basis of all that exists.
