Abstract
An argument for the historical continuity of Neo-Platonism and the Early Academy, resting principally on the positions held by 1) Posidonius on the relation between the soul and mathematics, 2) Speusippus on the relation between the One and the material principle, and 3) Boethius on the relation between degrees of being and degrees of knowledge. There is also an analysis of the elements of Neo-Platonism in Aristotle's metaphysics. A scholarly and readable book, certain to be controversial.--A. R.
