In this article, by analyzing the opinions of Avicenna and Moore, about the indefinability of good and bad morals, their attitude is explained from the epistemological point of view, The main problem of the research is Avicenna and Moore's attitude about criticizing the naturalistic criterion and criteria for carrying moral characteristics such as good and bad in moral issues. Avicenna states in his opinions that moderation as a metaphysical and natural matter cannot be a criterion for the good or badness of moral issues in all fields, and Moore, by analyzing the naturalistic fallacy, considers pleasure or harmony with nature as the criterion and criterion for carrying good and bad. He does not know moral issues. The results of the research show that the approach of these two thinkers to prove their claim is to pay attention to the logical problem that occurs in the comparison of knowing good and bad with things such as moderation, pleasure, and harmony with nature. To answer the problem, Avicenna and Moore defend the non-naturalistic realism of moral propositions, in the meantime, emphasizing the intuition of the characteristics in the intellectual intuition of the people to find criteria and criteria for the truth and falsity of moral propositions makes it possible to discuss the opinions of these two thinkers. The research method is to analyze the content of the opinions of these two philosophers in order to create a dialogue to compare their opinions.

This article explains and compares the views of Ibn Sina and G.E. Moore in the field of realist ethics and while discussing the method of intuition in recognizing moral characteristics. Realism in ethics means the objectivity of moral propositions, and therefore moral properties are intuitive. The main issue of research on the formulation of Ibn Sina's views, along with the principles of realism and the method of intuition, is whether the moral propositions under popular opinion follow the same principles that Moore put forward in the discussion of realism in ethics and how they can be intuitive. Moore's moral realism is based on the intuitionism of moral qualities such as good and evil, which are unacceptable to the natural or metaphysical. According to Ibn Sina, moral realism is defined and intuitive based on the moral presuppositions such as good and bad. In this attitude, the good and the bad for the soul are explained as a being whose exaltation and happiness is a real thing. The results of this study show that for Moore, the relationship between moral issues and predicates such as good and bad is an intuitive thing, which is defined as a good relationship with the greatest possible good, and this combination and understanding requires reflection and intellectual maturity of the moral agent. According to Ibn Sina, the relationship between moral issues and moral presuppositions such as good and bad is explained on the basis of the reputation of moral propositions and the intuitions of the wise of the people.
