Rational Intuition in Perceiving Intelligibles

In the Islamic philosophy, intelligibles are general concepts perceived by reason. These concepts which are independent from material accidents are found by the help of sensible things. There are many disputes among philosophers about the way they are formed and what that they represent. All Muslim philosophers are unanimous that rational forms and perceptions are immaterial. The problem of their permanence and generality may be solved if their immateriality is taken into account. Since they are immaterial, intelligibles cannot be found by and through senses, rather, they are perceived by reason. There are many pieces of evidence in sayings of the earlier philosophers about these points and based on which a common doctrine about perceiving intelligibles as rational intuiting can be depicted. Based on this solution, the way secondary philosophical intelligibles and consequences which are sought from such concepts may be explained. While explaining the solution of rational intuition, the author will discuss suspicions about this solution. When rational intuition of intelligibles is taken into account, the prevalent interpretation of the theory of immateriality seems not to be correct and it should be interpreted in another way and based on Peripateticism. And, the theory of rational intuition seems to be a correct one.
