This article presents a comparative analysis of the perspectives of Shahid Morteza Motahhari and Ayatollah Abdullah Javadi Amoli on "innate ethics." Both scholars, grounding their views in the Quran and opposing ethical relativism, argue that morality is rooted in humanity's unchangeable divine nature . Their fundamental agreement lies in rejecting the Hellenistic-derived theory of "rational good and evil," emphasizing instead the universality of ethical propositions. However, subtle distinctions exist in their epistemological explanations of this ethical innate disposition.

Shahid Motahhari adopts a holistic, pragmatic view, considering ethics an extension of "the truth of servitude to God" and based on inherent "innate inclinations" like truth-seeking, beauty-seeking, and self-dignity. For him, the moral conscience is active prior to rational deliberation, linking ethics to "practical self-awareness" and its social function. By comparing the aversion to lying to hunger, he anchors ethics in the human lifeworld.

In contrast, Ayatollah Javadi Amoli centers his framework on the "immateriality of the soul" and "intuitive spiritual wayfaring." He posits that ethical action is realized only through "presential knowledge," which removes dark veils and elevates the soul toward "immaterial perfection." Here, ethical cognition is more an inner revelation than a discursive process.

Ultimately, these perspectives are complementary facets of a single truth. Motahhari's focus on the "social function of ethics" and Javadi Amoli's emphasis on "existential teleology" together reveal the comprehensiveness of the Islamic theory of fitrah, presenting a unique paradigm against secular ethical systems.
