In 2012, my winter in Athens began with Aristotle＇s Metaphysics Zeta. Among strong classical philologists, 1 was the only student whose understanding of metaphysics had been based on Avicenna. After a while 1 found myself amid audiences beforehand precluded to compromise milestones of mine. But on the contrary, I embarked to reread both of the Avicenna and Aristotle from entirely different angle again. Inquiring in the concept of Being in both of the Aristotle and Avicenna was the first candidate of my decision. This paper is the result of mentioned concern. Aristotle＇s equivalence between the question of ＂what substance is＂ rendered to the question of ＂what being is＂ in addition to spelling out the implications of this observation done by Avicenna--basing on his own metaphysics---constitutes the body of my paper.
