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.
