Reale s monumental work establishes the exact dimensions of Aristotle s concept of first philosophy and proves the profound unity of concept that exists in Aristotle s Metaphysics. Reale s opposition to the genetic interpretation of the Metaphysics is an updated return to a more traditional view of Aristotle s work, one which runs counter to nearly all contemporary scholarship. Reale argues that Aristotle s first philosophy includes a study of being, a study of substance, a study of divine substance, and a study of principles and causes, all of which are integrated and dialectically reconciled."
