Republic

It would be absurd to suppose that the element of high spirit was not derived in states from the private citizens who are reputed to have this quality as the populations of the Thracian and Scythian lands and generally of northern regions; or the quality of love of knowledge, which would chiefly be attributed to the region where we dwell, or the love of money which we might say is not least likely to be found in Phoenicians and the population of Egypt. One certainly might, he replied. This is the fact then, said I, and there is no difficulty in recognizing it. Certainly not. But the matter begins to be difficult when you ask whether we do all these things with the same thing or whether there are three things and we do one thing with one and one with another—learn with one part of ourselves, feel anger with another, and with yet a third desire the pleasures of nutrition and generation and their kind, or whether it is with the entire soul that we function in each case when we once begin. That is what is really hard to determine properly. I think so too, he said. Let us then attempt to define the boundary and decide whether they are identical with one another in this way. How? It is obvious that the same thing will never do or suffer opposites in the same respect in relation to the same thing and at the same time. So that if ever we find these contradictions in the functions of the mind we shall know that it was not the same thing functioning but a plurality. Very well. Consider, then, what I am saying. Say on, he replied. Is it possible for the same thing at the same time in the same respect to be at rest and in motion? By no means. Let us have our understanding still more precise, lest as we proceed we become involved in dispute. If anyone should say of a man standing still but moving his hands and head that the same man is at the same time at rest and in motion we should not, I take it, regard that as the right way of expressing it, but rather that a part of him is at rest and a part in motion. Is not that so? It is. Then if the disputant should carry the jest still further with the subtlety that tops at any rate stand still as a whole at the same time that they are in motion when with the peg fixed in one point they revolve, and that the same is true of any other case of circular motion about the same spot—we should reject the statement on the ground that the repose and the movement in such cases were not in relation to the same parts of the objects, but we would say that there was a straight line and a circumference in them and that in respect of the straight line they are standing still since they do not incline to either side, but in respect of the circumference they move in a circle; but that when as they revolve they incline the perpendicular to right or left or forward or back, then they are in no wise at rest. And that would be right, he said.
