Edward C. Halper 
One and Many in Aristotle’s Metaphysics 
Alpha to Delta

In this first volume of One and Many, Halper argues that books Alpha to Delta should be read as a coherent treatment, within the larger whole of the Metaphysics, which addresses the problem of how there can be a single science of metaphysics. Halper shows that Aristotle poses and pursues the problem of the existence of metaphysics as a version of the problem of the one and the many, which he resolves by introducing doctrines of being and substance.
