practical reason

Since Kant is a son of his time, his thought is originally rooted in the Enlightenment. The distinction between theoretical and practical reason, formal and material conscientiousness, authentic and doctrinal theodicy, sincerity and falsehood, and finally, historical and moral faith religion, are implications of the court held by Kant for metaphysics. Meanwhile, Kantian distinction between deism and theism in one hand, and inclination toward Job and Christ as the symbols of moral faith of religion in the other hand, can be explained by the German Protestantism of the age of Fredrick the Great and his successor. The theology based on practical reason criticizes rationalism in faith and suggests perception of religion through morality. But, Aquinas as a Christian catholic emphasizes on historical religion, revealed religion, Divine legislation, faith in Divine worship and ecclesiastical faith. Aquinas is the most distinguished supporter of rational theology. However, he believed to other kind of theology named theologia sacrae scripturae or sacred theology which its main subject is Divine beings. The main bases of Aquinas‘s ethics are revelation and foundations of church. Kant, in the contrary, tries to make room for faith inside the realm of morality and speak of practical reason theology through denial of theoretical reason.  

Four different notions of freedom can be distinguished in Kant's philosophy: logical freedom, practical freedom, transcendental freedom and freedom of choice ("Willkiir"). The most important of these is transcendental freedom. Kant's arguments for its existence depend on the claim that, necessarily, the categorical imperative is the highest principle of reason. My paper examines how this claim can be made plausible.

Introduction: In this comparative research, while discussing free will as the basis of moral action, Mulla Sadra's and Kant's views were examined. In examining Mulla Sadra's views, his fundamental approach in relation to free will and the fruit of practical reason, i.e. the attainment of transcendental agency, has been considered as the main paradigm. Material and Methods: The research method is logical analysis on the use of library texts. Conclusion: From the comparison of these two theories, it can be concluded that Kant's theory has led to humanist ethics due to benefiting from the essence of human knowledge and using elements such as independence of will. Because according to Kant, man has a true identity and is free from all external and transcendental factors. According to him, independence of will is the highest principle of morality. Mulla Sadra's theory is an epistemological-divine theory and his epistemological basis is also rooted in the beyond. From his point of view, although man is a creator, but he is really the same as belonging, needing, and connecting with the origin of existence, that is, God, and Mullah Sadra's upward course is based on the movement of his essence, the originality of his existence, its skepticism, and the connection of man with the holy intellect and the active intellect, and finally it shows communication with God; that man has no independence from himself and his whole existence is mortal in the existence of the Almighty. Kant considered will and free will as the most fundamental bases, while Mulla Sadra considered theoretical reason to be the basis of human knowledge

Practical reason is the use of reason to decide how to act and perform in a social reality. When someone deliberates about what to do, one puts all the reasons for the action, and then all the reasons against the action will determine the outcome of the action. In that situation, we can describe that practical action with reason because we will determine reason with the weight of different reasons not on the weighing reasons. In this paper, we analyze that reasons have weight against the theory that weights of reasons have no role in a theory of reasoning, and defend that reasons have weight with the evidence of practical reasons. The aim of this paper is to argue that weight of reasons has a role in the process of reasoning. In every situation of life, we can use have reason and weight of reason according to the practical situation of life.

The concept of human perfection is a universal concern that has occupied thinkers from various schools of thought, including Mulla Sadra. This study employs a descriptive-analytical and library-based methodology to examine Mulla Sadra's perspective on the perfect human being. The analysis reveals that humans are inherently driven towards perfection, and Mulla Sadra's philosophy emphasizes instructing how individuals can progress toward this ultimate state. From Mulla Sadra's perspective, human being   is the pinnacle of existence, possessing inherent dignity. However, to realize this, humans must embark on a path of perfection. This perfection lies in the development of their rational faculty, which sets them apart from other beings. Human intellect has two aspects: theoretical and practical. The complete development of both these facets is essential for human perfection.
