A Comparative Study of the Development of Conventional Propositions from Farabi and Ibn Sina's Point of View

This article seeks to explore the factors involved in the development of propositions referred to in logic as conventional propositions. It will examine conventional propositions from Farabi and Ibn Sina's points of view. In Farabi's works, we dont see any direct and clear reference to conventional propositions. However, by reflecting upon his works we can understand how conventional propositions are formed. Unlike Farabi, Ibn Sina has coherently dealt with the factors involved in formation of conventional propositions and in some of the most important ones, he shares Farabi's views implied in his works in this regard. On the whole, it can be said that the main objective for Farabi's discussion about the formation of such propositions is to reach true happiness. In Ibn Sina's works, conventional propositions are taken to bring about positive changes in communities. Finally, Farabi and Ibn Sina have suggested that the inheritors of their knowledge take care of inquiries about the practical wisdom and political philosophy.
