Philosophical Secondary Intelligible in Allameh Tabatabai's Point of View

The intelligibles are general concepts and are divided in three kinds: Primary Intelligibles, Logical Secondary Intelligibles, and Philosophical Secondary Intelligibles. Allameh Tabatabai defines philosophical secondary intelligibles as concepts whose their predication is mentally and their qualification is externally. He emphasizes the role of intuitive knowledge in achieving these concepts. He describes frankly some concepts as philosophical secondary intelligibles, such as Existence and Non-existence, Necessity and possibility. About some else conceps, Allameh doesn’t speak frankly and even describes them as primary intelligibles, but based on his philosophical elements, we can considere them as philosophical secondary intelligibles. In Tabatabai's thought, philosophical secondary intelligibles have several features, the most important of which is the abstraction from the findings of intuitive knowledge. This paper, with a descriptive-analytical method, peruses the whatness and examples of philosophical secondary intelligibles in Allameh Tabatabai's thought.
