Given that the effects of the lack of moral sovereignty are becoming increasingly apparent in societies, and that especially developed societies in this regard are encountered with widespread challenges, discussion about moral philosophy is inevitable. Differences of opinions in moral philosophy have made the comparative comparison of different perspectives in this respect doubly important. Relying on specialized sources and comparative comparisons, in this research, we seek to answer what the main differences are between martyr Motahhari and McIntyre as representatives of Islamic and Western ideas in explaining the meaning of virtue. Belief in relativism, independence in the development of the program of happiness, belief in the historical context of the emergence of virtue, and knowledge of virtue as intermediate are among the most important elements that distinguish these two views. Based on the arguments presented, it can be concluded that although McIntyre’s thought is a defensible theory in ethics, it has shortcomings in comparison with Islamic thought.
