Analyzing pleasure in Ibn Sina's view and critical the interpretation of Khaje Nasir- Altosi

In Ibn Sina's view, "pleasure" is one of the qualities of the ego. It's conceptual is present perception. In his book, " Al-isharat wa al-tanbihat," he describes pleasure is a perception and achievement to something that is perfection and goodness in the human. Who percept it. Since in this description, contrary to other descriptions, for the description of pleasure he has used the word "Neil", some researchers have conceived that "Neil" refers to the present perception of the essence of evidence in Ibn Sina's mind. whereas that's a contradiction with his philosophy. This idea has been raised by Khaje Nasir al-Din and reflected in new researches. Even some researchers, based on this interpretation, have explained the mistakes of pleasure in the thought of Ibn Sina. Therefore, it is necessary to analyze by descriptive-analytical method his description of pleasure in the book. The results of the research show that basically, the interpretation of the achievement to the present perception as a pleasure of perceptibility is not acceptable.
