Meshai tradition and İbn Bajjah's nafs idea -investigating his opinions about human psychology in the context of "Kitab'an Nafs"-

The concept of nafs in Islamic philosophy has played many roles in epistemology, ontology, cosmology and eschatology. Almost all of the Islamic philosophers have written a book about nafs or opened a section on the subject in their works and discussed this discussion in detail. Therefore, in order to analyze a text about Islamic philosophy, it is vital for us to comprehend how philosophers draw the concept of nafs and its meaning framework. Ibn Bajjah's forms of approach presented in Tadbir Al-Mutavahhit gives us important clues on the man's of ripening and the point of revealing ability of self-expression. However, the preparatory of this work is actually Kitabu'n-Nafs, especially what nafs is and how it solves the issues in terms of sensation and thought shows the way of thinking of our philosopher. The establishment of all systems of Farabi and Ibn Sina within the framework of God, Nous and Nafs influenced the ideas of later philosophers such as Ibn Bajjah. Ibn Bajjah also wrote the book called Kitabu'n-Nafs revealed the importance of nafs and he tried to put forward what the nafs is and the processes of acquiring knowledge in sensory and mental sense. In Ibn Bâcce, the spirit that builds the humanistic and divine aspect is also used in the sense of nafs. Nafs is expressed as the competence of the body. The fact that a person has a healthy spirit world will affect his decisions as well as his body health on solid foundations. Will and responsibility play an active role in ensuring the divine aspect of the human soul or in its inferiority. It is in the person's own hands to become competent by coming out of the particular by reaching the knowledge of the universal. This effort is also supported divinely and leads to human perfection. The person who reaches the highest level in terms of mental competence will affect the development and transformation of the society by sharing this gain with other people. The Mutavvahhit Theory put forward by Ibn Bajjah is the activity of directing the whole society for the good starting from the individual. This transformative activity, with its peaceful nature, can be a role model for today's cosmopolitan societies. It has also been designed as an individual way out for intellectuals who are in conflict with the contradictions of society. In any case, the fact that it targets the happiness of both the individual and the society will shed light on the problems of our age.
