In Avicenna’s view, the practical intellect plays a basic and foundational role in producing moral action. By investigating this notion in the framework of Avicenna’s philosophy, we find that he regards perception and cognition as the main functions of the practical intellect. However, he considers this perception as particular, introducing it as different from the particularity of imaginary and estimative cognitions (animal perceptive faculties). This difference makes the action produced by an animal essentially different from the action produced by the practical intellect. This view, however, is contrary to the views of some other philosophers and theologians who disagree with him on the perceptive function of the practical intellect and maintain just a motivational function for it. In addition, Avicenna enumerates the following as other roles of the practical intellect in producing moral action: motivational and incentive function; dominance over motivational and inclinative (to or against) faculties, etc and being served by them; serving the speculative intellect and purifying, completing and refining the speculative intellect in the realm of the practical intellect. Many other points have also been mentioned in this regard within this article. Overall, the central role of the practical intellect in producing moral action in Avicenna’s view gives rise to other discussions regarding moral action as well, in a way that those discussions are based on, or lead to it directly or indirectly.

The companies with major customers can supply a considerable source of cash flows by selling a large portion of their products to them. Since the lack of purchase, loss, or bankruptcy of major customers can result in a significant reduction in cash flows in the company, thus the risk is the companies with major customers is higher than other companies. Thus, the present study aimed to investigate the effect of customer concentration on company risks. For this purpose, the effect of customer concentration on three criteria of stock price crash risk, bankruptcy risk, and employment risk was studied. The research sample included 127 companies listed in the Tehran Stock Exchange during 2011-2018. Multivariate regression models with panel data were used by the random-effects method to test the research hypotheses. The research findings indicated that customer concentration has a significant positive effect on stock price crash risk, bankruptcy risk, and employment risk. In other words, stock price crash risk, bankruptcy risk, and employment risk are higher in the companies where the concentration of major customers is higher.
