Metaphysics

Across fourteen books, Aristotle defines what it would mean to have a science of being itself: of the categories that classify what is, of the causes that explain why anything is what it is, and of the highest cause — the unmoved mover — that draws all motion toward itself. The Metaphysics is not a single argument but a sustained interrogation, written in fragments and revisited returns. Book Alpha gives us the famous survey of his predecessors, Books Zeta and Theta the heart of substance theory, and Book Lambda the proof of the unmoved mover that would shape every major theology since.
