SUBJECT & OBJECTIVES: Moral realism means that moral values are real regardless of feelings and emotions, collective agreement, and the orders of anyone. This article aims to explain the relationship between Mulla Ṣadrā's viewpoint and moral realism, as well as the influence of his thoughts on our lives.   METHOD & FINDING: The research benefitted from an analytical-descriptive method. At first, by referring to all the works of Mulla Ṣadrā, his moral ontological foundations were deduced, and based on his statements and foundations, it was analyzed in an integrated manner and finally, its effect on pure life has been explained. We have concluded that based on Mulla Ṣadrā's idea, he is a realist. We can enumerate the following shreds of evidence to prove this claim: 1) The reality of the moral criterion, 2) The criticism of divine command theory, 3) The real basis of moral judgments, 4) The consequences of moral judgments, and 5) The manifestation of inner attributes. Additionally, we have demonstrated that action based on the realistic foundations of Mulla Ṣadrā will direct life towards a divine life with true happiness and will suggest a different way of life.CONCLUSION: Action based on the realistic principles of Mulla Ṣadrā will guide life towards a divine life with true happiness and will suggest a different way of life.
