Dividing general concepts into primary and secondary intelligibles is one of the important foundations of Islamic wisdom, which plays a key role in solving problems in the rational sciences. Secondary philosophical intelligibles have gained a central position due to their specific characteristics. Emphasizing the distinction between these concepts and the first and second logical intelligibles, Allamah Misbah Yazdi considers neglecting this division to be the source of many philosophical errors. Using an analytical-descriptive method, this research explains the fundamental role of secondary philosophical intelligibles in moral philosophy from the perspective of Allamah Misbah Yazdi. The findings show that the basic concepts of ethics are of the type of secondary philosophical intelligibles. Accepting this premise has far-reaching consequences: The realism of moral propositions, the possibility of solving the problem of “inferring the ought from the is”, criticism of relativism and unrealistic moral schools, and criticism of some Western moral schools such as Kant. This article concludes that adherence to this theory not only provides a robust strategy for defending the objectivity of morality, but also constitutes an essential framework for any research into Islamic moral philosophy.
