Reason as one of the most important sources of cognition from the perspective of Mulla Sadra and Isfahani

One of the concepts with different and much definitions is the word reason. Some groups considering it equally with human being, others disagree and calling it the origin of misleading and fell out of the range of devotion to divine. Some equivalent it with philosophy and a group have ruled to the need of separation between the reason and philosophy. Although philosophers endearing reason, tradition believers and Ash'arite rejected it. Mulla Sadra knows reason as the analyst power for situations and modes of soul which includes a broad extension from primitive reason to acquired reason; while the wisdom in perspective of Mirza Mehdi Isfahani has an independent and light entity, "In essence is illustrative and luminous to others. In essence is innocent and has independent entity". That is imparted by God. The reason from his look is only enlightening the truth, and is not even the Analyst of human soul modes. The present study investigates the subject in idea of two great Islamic scholars, Mulla Sadra, the founder of the eminent wisdom and Mirza Mehdi Isfahani, the founder of the school of distinction. We will attempt to understand the similarities and differences between them by comparing these two thinkers' views about the reason.
