Avicenna’s (Ibn Sina) Natural Philosophy

Ibn Sina, one of the most influential philosophers of the Islamic civilization, discusses his philosophical views with integrity in his book, Kitab al-Shifa (Book of Healing). The first book of the second part of the Book of Healing, called The Physic, reveals his detailed philosophy on nature. Although Ibn Sina's philosophy of nature has been extensively analyzed about the concepts of motion, time, and place, there is a need for a comprehensive study that examines this subject from a historical perspective, covering all aspects of it. The author gives a comparison between the natural philosophy of Ibn Sina and the explanations of previous philosophers specifically Aristotle in her work 'Avicenna's (Ibn Sina) Natural Philosophy'. The discussion of the natural sciences centers primarily around method and subject, with a dedicated section for defining the term 'nature'. The subsequent sections delve into great detail regarding the causes that impact objects as subjects of the natural sciences, as well as their causal relationships. Since the work is a subject of natural sciences, it is completed with motion; time and place are the primary variables in defining motion. The work aims to compare Ibn Sina's natural philosophy with the views of previous philosophers and highlight the differences. It also explains the evidence and logical system that Ibn Sina used when presenting this philosophy. Our aspiration is that this research will make a meaningful contribution to the disciplines of natural sciences and philosophy.
