One and many in Aristotle's Metaphysics. / Books alpha-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.
