Abstract

There are three main views of the development of Plato’s distinction between being and becoming which have been defended in recent times. Most scholars have thought that Plato always held the same version of the distinction despite appearances to the contrary. But some who have taken this position have thought that Plato took the realm of being to consist of things which never change in any way, and the realm of becoming to consist of things which are never stable in any way. Others have thought that Plato’s account of things in the realm of becoming was not so extreme. They have maintained that the realm of being is made up of things which never change in any way, but that the realm of becoming consists of things which constantly change while they exist in many ways. The third view belongs to those who have held that Plato did in his middle dialogues take the extreme view of becoming and the extreme version of the distinction which that entails. But later, they claim, he discovered that the distinction was incoherent. He therefore abandoned it, and the metaphysical doctrine of degrees of reality which he had based on it, altogether.
