The concepts of good and evil in avicenna's philosophy

Avicenna is the most significant philosopher of the Islamic Philosophical tradition in the Farabi School. He is considered to be the greatest philosopher in Mashshai (peripatetic) school after Farabi. His moral philosophy includes similar views with his predecessors such as Plato, Aristotle, Farabi, and Ibn Miskeveyh. He addresses topics such asethics and human happiness in his encyclopedic treatises and other treatises he wrote. In Avicenna's understanding of morality, the aim of man is to reach happiness and this is only possible by having good morals. In his philosophy of ethics, the essential thing in the universe is goodness and the evil is faulty. The aim of this study is to provide a comprehensive understanding of Avicenna's good-bad understanding, which is reflected in his work within the general moral philosophy. For this reason, Avicenna's predecessors Aristotle, Plato, Farabî and İbn Miskeveyh's moral philosophies and understanding of happiness have been discussed firstly in the study in general terms. Then, Avicenna's thoughts on good and evil within the philosophy of morality have been evaluated.
