Scientific and Ethical Perfection from Khawje Nasir's Viewpoint

This study intends to analyze scientific and ethical perfection from the viewpoint of Tusi. In analyzing perfectionism, we begin with analysis of the concept of perfection. Dimensions of human perfection (scientific and ethical ones), stating the degrees of human perfection and practical procedure and process of human perfection from Tusi’s viewpoint are other issues discussed in this paper. Dimensions of human perfection in accordance with human soul forces (theoretical and practical forces), Tusi’s interpretations from the function of these forces are different in his works. According to him, with regard to various functions of the forces, scientific and practical perfection will also be various. Scientific perfection is knowledge-based while constitutional facts (insights) and ethical perfection are from particular cases of knowledge and practical effects. In fact, Tusi’s ethical theory extends beyond the soul’s health and it is indicative of high-level ideals, i.e. soul’s perfection. As an ideal of ethics, perfection has degrees which could be shown by horizontal hierarchy of perfection. Tusi believes that regarding the stages of perfection in philosophical works the focus is on nonessential forces of soul and in mystical works, the attention is directed towards manners of soul and its horizontal existence shields. The process of perfection has two scientific and ethical dimensions and Tusi has proposed a practical procedure for perfection and has not merely theorized.
