‘All the difficulties in the theory of forms arise from their separation.’ This recurrent criticism of Aristotle's is, of course, one of the principal obstacles in the way of any reconstruction of the Platonic metaphysic. To begin with, it is flatly denied by Plato himself in the use of such words as μέθεξις, παρoυσία and κoινωνία. It must also be rejected by the orthodox account of the Forms which takes them to be immanent, constitutive principles in the world of everyday (...) life, like a Law of Nature or the Concrete Universal of Hegel. Finally, modern philosophy has made it clear that this view of universals is right and necessary if thought and language are to exist, and it is therefore tempting to attribute it to Plato. (shrink)
