تحلیلی بر معنای امکان اخص از منظر ابن سینا

Abstract

Abstract Avicenna (Ibn Sīnā's) discusses in detail the modality and modal syllogistic, in his logical books. The earliest formal system of modal logic was developed by Avicenna, who ultimately developed a theory of "temporally modal" syllogistic. However, referring to his works, there is a kind of ambiguity in the meaning of narrowest possibility. Some Western logicians have also reported such ambiguity, sometimes leading to misunderstandings. Therefore, knowing the exact meaning of the narrowest possibility from Avicenna's perspective is important. In the book of Healing (Kitāb al-Shifā, Kitāb al-Burhan), it becomes clear that his definition of the narrowest possibility is the same as the definition of a future possibility. In the book of Oriental logic (Mantiq Al-Mashriqiyin) and the book of Pointers (Al-Isharat wa’l-Tanbihat), the narrowest possibility and future possibility are defined separately, but the definitions provided do not completely coincide. Two strategies will be proposed to resolve this ambiguity. Finally, it seems that there is no real distinction between the narrowest possibility and future possibility. That is, the distinction between these two possibilities depends solely on whether it is a consideration for the future or not.
