memory; and the Other moves it again in the difference between past and present, touching at the same time upon diversity and identity. 25. But now let us take a draught of the corresponding composition of the soul from the structure of the body of the universe. There we find fire and earth, whose nature is such as not to admit of mixture one with another but with great difficulty, or rather is altogether obstinately refractory to mixture and constancy. God therefore, placing air and water in the middle between both,—the air next the fire, the water next the earth,—first of all tempered the middlemost one with another, and next, by the assistance of these two, he brought the two extreme elements not only to mix with the middlemost, but also to a mutual closure or conjunction between themselves. Then he drew together those contrary powers and opposing extremes, the Same and the Other, not immediately, the one adjoining to the other, but placing other substances between; the indivisible next the Same, and the divisible next the Other, disposing each to each in convenient order, and mixing the extremes with the middlemost. After which manner he interweaved and tissued the whole into the form and composition of the soul, completing, as far as it was possible, similitude out of things different and various, and one out of many. Therefore it is alleged by some, that Plato erroneously affirmed the nature of the Other to be an enemy to mixture, as being not only capable to receive it, but a friend of change. Whereas that should have been rather said of the nature of the Same; which, being stable and an utter adversary to mutability, is so far from an easy and willing condescension to mixture, that it flies and abhors it, to the end it may preserve itself pure and free from alteration. But they who make these objections against Plato betray their own ignorance, not understanding that the Same is the idea (or essential form) of those things that always continue in the same state and condition, and that the Other is the idea of those things which are subject to be variously affected; and that it is the peculiar nature of the one to disjoin and separate into many parts whatever it happens to lay hold upon, and of the other to cement and assimilate scattered substances, till they resume one particular form and efficacy.
