Schopenhauer's Metaphysics and Plato's Concept

There are controversies over the use of Plato's concept by Schopenhauer in his metaphysics.On the one hand,Plato's concept plays a positive role in constructing Schopenhauer's metaphysics;on the other,his use of such concept is quite different because his metaphysics of will deviates from Platonism,which has led later philosophers like Nietzsche to subvert the metaphysical tradition of Platonism,that is,the end of metaphysics.
