One of the most fundamental philosophical and theological inquiries throughout history has been the relationship between reason and religion. The central question is whether epistemic authority lies with human intellect or divine revelation. In this context, this study examines the relationship between reason and faith in the intellectual framework of Morteza Motahhari and its influence on the discourse of the Islamic Revolution. The hypothesis suggests that as a leading contemporary scholar, Motahhari engaged deeply with the philosophical aspects of the reason-religion dynamic, articulating a rationalist approach within his works. Given his significant role in shaping the ideological foundations of the Islamic Revolution, his views on this subject inevitably influenced the intellectual discourse of the revolution. This research, employing an interpretive-explanatory approach and utilizing documentary and library sources, finds that Motahhari consistently emphasized a rational interpretation of religion. His approach not only integrated reason into religious exegesis but also extended rationality into his understanding of political Islam.
The question of the relationship between reason and religion has long preoccupied theologians and philosophers. The central debate revolves around whether divine revelation and rational thought are inherently contradictory or complementary sources of knowledge. Some historical perspectives, particularly within Western positivist historiography and materialist sociology, have dismissed religion as an irrational and mythical construct. Figures such as Joseph Lafitau, Max Müller, and James Frazer viewed religious beliefs as primitive and irrational, while 19th-century materialist sociologists like Feuerbach and Marx saw religion as a byproduct of human immaturity.
Conversely, many scholars argue that religion and reason are not necessarily in conflict. Some religious traditions emphasize that faith does not contradict logic but rather complements and reinforces it. This has led to a long-standing debate across various intellectual traditions, from medieval Christian theologians to Islamic philosophers. Thinkers such as Augustine and Thomas Aquinas in the Christian tradition, and scholars in Islamic philosophy, have examined the interplay between reason and faith.
In Islamic thought, this debate has been particularly prominent, with some schools of thought advocating a complete separation between reason and revelation, while others—such as the Mu‘tazilites—have sought to harmonize the two. Within Shia Islam, the balance between intellect and faith has been a core component of theological discourse. In this context, Morteza Motahhari, as one of the most influential contemporary Islamic thinkers, engaged deeply with the question of reason and religion. His views played a crucial role in shaping the intellectual and ideological foundations of the Islamic Revolution. This study explores the fundamental question: What is the relationship between reason and faith in Motahhari’s thought, and how did it influence the discourse of the Islamic Revolution?
Theoretical Framework: Rationality and Religion
The debate over the compatibility of reason and religion is a longstanding issue in philosophy and theology. Some scholars argue for a fundamental incompatibility between rationality and faith, while others suggest a harmonious relationship between the two. The reconciliation or divergence of reason and religious belief significantly influences epistemology, ethics, and political philosophy.
One of the central issues in this debate is the role of reason in evaluating religious beliefs. Key questions include:

What is the nature of rationality, and how does it interact with religious knowledge?
Can rational analysis be applied to religious doctrines?
Does faith require rational justification?

Throughout history, thinkers have developed different models to address these questions. Augustine, for example, argued that divine illumination enables human reason to perceive eternal truths. Thomas Aquinas, building on Aristotelian philosophy, posited that reason and revelation are not contradictory but rather different expressions of the same truth. In contrast, fideist perspectives hold that faith is independent of, or even superior to, rational thought.
In the Islamic tradition, figures such as Al-Farabi, Avicenna, and Mulla Sadra have examined the role of reason in understanding religious truths. Shia theology, in particular, has emphasized the compatibility of intellect and revelation. The hadith from Imam Musa al-Kadhim stating that "God has two proofs upon mankind: an external proof (the prophets and imams) and an internal proof (human reason)" reflects this perspective.
Motahhari’s intellectual framework aligns with this tradition, arguing for the integration of reason and faith. His works emphasize that Islamic teachings are fundamentally rational and that reason serves as a critical tool for understanding religious principles.
Findings

The Rational Foundation of Islamic Teachings

Motahhari’s works demonstrate a strong emphasis on rationality within Islamic teachings. He argued that the Quran does not promote blind faith but instead encourages rational inquiry. According to him, Islamic epistemology is based on logical reasoning rather than dogmatic adherence:
"Islam assigns immense value to human reason, thought, knowledge, and scientific investigation. The Quran consistently calls upon individuals to reflect and contemplate, avoiding blind imitation in matters of faith." (Motahhari, 1989, p. 185)
He further maintained that the Quranic approach to belief is based on intellectual conviction rather than emotional or mystical experience. For example, Quranic verses frequently appeal to reason by presenting logical arguments for divine existence and moral principles.

Reason as a Tool for Religious Interpretation

Motahhari viewed rationality as essential in interpreting religious texts. He argued that Islamic jurisprudence and theology must be grounded in reason to ensure their relevance and adaptability. His perspective aligns with the principles of ijtihad (independent reasoning) in Islamic law, which allows for continuous reinterpretation based on rational analysis.

Motahhari’s Critique of Secular and Extremist Views

Motahhari was critical of both secular rationalism, which sought to exclude religion from public life, and religious extremism, which rejected rational inquiry. He argued that a purely secular perspective leads to a spiritual void, while an anti-rational religious stance results in dogmatism and stagnation. His balanced approach aimed to integrate rationality within religious thought without succumbing to either extreme.

The Influence of Motahhari’s Thought on the Islamic Revolution

Motahhari’s emphasis on the compatibility of reason and faith played a crucial role in shaping the intellectual discourse of the Islamic Revolution. He rejected the Western secular model, which separates religion from politics, while also opposing fundamentalist interpretations that dismissed rational discourse. His vision of an Islamic state was one in which governance was informed by both religious principles and rational policymaking.
He argued that the revolution was not merely a political upheaval but also an intellectual and spiritual movement. His ideas provided the ideological foundation for a political system that sought to balance Islamic teachings with modern governance structures.
Conclusion
The relationship between reason and religion has been a central debate in philosophy and theology. This study examined Morteza Motahhari’s views on this issue, highlighting his rationalist interpretation of Islam and its impact on the Islamic Revolution.
Motahhari’s approach demonstrates that he saw no inherent contradiction between reason and faith. He argued that Islamic teachings are fundamentally rational and that intellectual inquiry is essential for understanding religious principles. His emphasis on rationality influenced the discourse of the Islamic Revolution, shaping its ideological foundations and contributing to the development of an Islamic governance model that integrates both reason and faith.
By advocating for a rational interpretation of Islam, Motahhari provided a framework that continues to influence contemporary Islamic thought. His legacy serves as a testament to the possibility of harmonizing intellectual inquiry with religious belief, offering a model for a modern Islamic state that upholds both rationality and spirituality.
