A Model for Human Action Based on Sadra’i Wisdom

Introduction
An action is an external behavior formed through an interplay between knowledge and inner tendencies, and then actualized via will or volition. On this picture, an action begins from a conception and assent (affirmation) within an epistemic process, leading to decision-making and will. Several factors, such as the imaginative faculty, the faculty of theoretical and practical reason, the craving faculty, and will, contribute to this process. Accordingly, various types of human action are formed given the order of functioning as well as the intensity and strength of these faculties. Hence, the existence of various possibilities and circumstances for the interactions of these principles demand different models for human action. A consideration and comparison of these factors can play a role in analyzing and explaining the human action as well as presenting various solutions to change, modify, or even reinforce human behaviors. To do so, a survey was conducted in the works of Mullā Ṣadrā deploying the descriptive-analytic method to identify various models of human action and pinpoint their differences and the conditions in which they occur. The main problem of this research is:
What is the fundamental and basic model of the human action and what are the models branching from them?
The secondary questions include the following:

How do models of human action differ from each other and from the model of action in animals?
What is the role of temperament in the model of human actions?

Research Background
Thus far, several studies have been carried out concerning the philosophy of action and how an action is produced within the framework of Mullā Ṣadrā’s philosophy. Rezaee and Houshangi (2013) in “The process of the production of human voluntary action,” Shahgoli (2019) in “Principles of action in the views of Fārābī and Mullā Ṣadrā,” and Mirhadi (2018) in “Philosophy of action in Transcendent philosophy” aim to introduce the principles and preliminaries of action and the stages of the production of an action from the perspective of Muslim philosophers, particularly Mullā Ṣadrā. Vafaeian and Gharamaleki (2017) in “An ontological analysis of the process of the production of actions from the perspectives of Avicenna and Ṣadr al-Mutaʾallihīn” assert that they are concerned with the ontological status of the principles of the production of action. Soleimani (2020) in “The place of action in human existence in Mullā Ṣadrā’s view” provides an account of the formation of action and the longitudinal relationship between its principles, stating that Mullā Ṣadrā views the inner reality of an action as its longitudinal principles, while external action is solely a manifestation and expression of this longitudinal chain of the functioning of perceptual and motive faculties of the soul. Varzdar and Ketabchi (2022) in “The study of the function of practical reason in the process of action production in Transcendent philosophy” are focused on the role of practical reason in the process of the production of actions.
The contribution of the present research, which sets it apart from the above-mentioned studies, is that it addresses the numerous models and schemas of the order and mode of the functioning of the formative principles and elements of action.
 
Conclusion
When doing an action, the human individual employs the numerous faculties and powers of their soul, including perceptual and motive faculties. Given the order of functioning as well as the intensity and strength of these faculties, various types of human action are formed. Thus, a model and schema can be determined for each type of human action. All conceivable models of human action involve a transition from the cognitive principle to determination, will, and production of the outer overt action. In other words, all varieties of human actions are formed based on a basic model. This foundational model shows the general course of the soul’s linear motion from the highest to the lowest principles that contribute to the actualization of action.
Regarding the basic fundamental model of human action, stages can be devised as follows:
In the first stage, the desired goal and objective are determined by theoretical reason. In the second, the proper action to fulfil the goal is selected and confirmed by practical reason. In the third, the requisite proper urge and motivation are produced by the craving faculty under the governance of practical reason. In the fourth, rational urge prevails and intensifies and then determination and will are formed for doing the action.
In the model of deterministic action, the urge resulting from the confirmation by practical reason is not agreeable to nature, but the action is selected and preferred by the cognitive system and then confirmed by reason. Accordingly, an action not being agreeable is compatible with its volitional and free character.
In the model of animal action, humans just like animals have a presence-based comprehension of an instinctive impulse and need within themselves, then conceive a particular action in their imaginative faculty as well as the pleasure or pain associated with the action, and then through appetitive or irascible faculties, an urge or repulsion towards the action ill be produced in the individual. If the urge is bolstered and prevails, the will to do or omit the action will be formed.
In any event, Ṣadrā believes that urge and will in humans are governed by reason. It is only in this case that the will can be rational and human. However, if the urge and will are governed by instincts, senses, and imagination, which yields a speculative judgment by reason, the will is animal.
When the action occurs, its wanted or unwanted consequences can have an effect on the constitutive elements of the action. This means that they have a reinforcing or undermining effect on instincts and inner impulses, knowledge, desire, and will. Nevertheless, this effect is only indirect. In case there is a positive effect, which reinforces the principles of an action, the action will be repeated frequently. This will lead to a particular psychological habit in the individual, which is called a “temperament” or “character.” According to the principles of Sadraean philosophy, a soul that possesses a temperament changes its substantial form, and given the new stage of its psychological forms, it comes to have new and stronger faculties and powers. Later, the principles of the action will be further solidified and their functioning in inducing actions will be quicker, such that the actions associated with that stage of the soul will be produced more easily.
