Its nature is to be the recipient of Forms. In itself it is no thing (to nh ov), though not absolutely nothing (owe ov). In the Timaeus, 'primary Matter' cannot be distinguished from Space in three dimensions.

It is constant only in change (ia-rtiKot owe iv a-ratrei); it 1 Moore (Home University Library--' Nature and Origin of Life ') thinks it probable that atoms are generated out of the ether. Mendeleeff, too, has argued that the ether, instead of being some mysterious form of non-matter, is the lightest and simplest of the elements. . . . The atomic weight of the ether he...
