Abstract

The scientific legacy of Ibn Sina, who sealed his place in world medicine, is a very rich and priceless treasure. It is no exaggeration to say that Abu Ali ibn Sina devoted his life to the study of human health. The second is intermittent and is called "munfasil" in Arabic. Everything in existence, quantity and quality in the subject and process are inseparable, manifested in unity. Adjective in Arabic means "mood", quantity in Arabic means "kamiya". There is no immutable object in the existence of nature. But the whole existence of nature changes within itself. The norm is a multifaceted, substantive category in the teachings of Ibn Sina.
