One of the difficulties of understanding and commentating on Aristotle’s “Metaphysics” is understanding the structure of it. While ancient commentator of metaphysics regarded it as one collection that have Coherent structure, most of the modern commentators on Aristotle hold that this collection does not have unity and its topics, specially topic of ontology in middle books and topic of theology in final books, do not have philosophical consistency with each other. In this essay, based on problems of book III (B), which can be regarded as Metaphysics’ table of contents, it is tried to offer a theory about structure of Aristotle’s Metaphysics and to criticize different theories in this matter.
