Various perspectives exist regarding theoretical reason ('aql nazarī) and practical reason ('aql 'amalī). For instance, some consider theoretical reason responsible for all cognitive perceptions, while practical reason governs action and motivation. Others view theoretical reason as the center for perceiving universals, whereas practical reason deals with particulars. The main question of this research is: What is the innovative viewpoint of Professor Javadi Amoli on theoretical and practical reason? The findings of this study are as follows:
1. According to Ayatollah Javadi Amoli, theoretical reason is responsible for understanding, thought, certainty, and 
conviction, while practical reason governs inclination, intention, motivation, faith, piety, trust in God (tawakkul), patience (sabr), sincerity (ikhlas), love, enmity, power, and resolve. Human flourishing (sa'āda) results from the harmony between 
theoretical and practical reason in establishing these two connections. Additionally, theoretical reason is responsible for 
perceiving all issues of theoretical and practical wisdom (hikma), but it is practical reason that ensures the actualization of practical wisdom.
2. In an innovative approach, based on distinguishing the functions of theoretical and practical reason (where perception is the function of theoretical reason and inclination is that of practical reason), he presents the self-evident nature (badāha) of theoretical and practical reason as fundamentally different. That is, the self-evidence of theoretical reason is of the nature of perception, whereas that of practical reason is of the nature of inclination.
3. Ayatollah Javadi Amoli’s view aligns closely with the position hat theoretical reason is the source of perception, 
while practical reason is the source of motivation. However, his perspective is formulated in such a way that it avoids the 
criticisms leveled against the aforementioned view.
