Comparison of philosophical thoughts within the Islamic tradition

The Sinan approach to the theory of definition is an explanation and expanded from of Aristotelian definition. He has accepted Aristotle’s definition of objects based on analyzing their quiddity in terms of their genus and differentia and extended it. Moreover, Ibn Sīnā has added some innovative views to it that have not received the attention that they truly deserve, and researchers have not explained and organized them in a consistent and structured from. Following a descriptive-analytic method, this paper explains the theory of Sinan definition within a consistent framework and analyzes the quality of Ibn Sīnā’s encounter with the views of Aristotle and Fārābī. Moreover, it refers to Ibn Sīnā’s innovations regarding the problem of definition and, by emphasizing its less studied aspects, responds to the following questions: to what extent is the unknown nature of objects’ differentia consistent with Ibn Sīnā’s theory on the definition and knowledge of objects? Does the theory of Sinan definition merely target quiddative affairs, or does it also extend to non-quiddative affairs? Which mechanism does Ibn Sīnā provide for defining non-quiddative affairs?
