Here is a prisoner, with his hands tied and a cord round his neck (as suggested by figures in Assyrian bas-reliefs), being led home by his savage conqueror, who intends to make him a slave. The one you say is captive and the other free. Are you quite sure the other is free? He holds one end of the cord and, unless he means his captive to escape, he must continue to be fastened by keeping hold of the cord in such way that it cannot easily be detached. He must be himself tied to the captive while the captive is tied to him. In other ways his activities are impeded and certain burdens are imposed on him. A wild animal crosses the track and he cannot pursue. If he wishes to drink of the adjacent stream he must tie up his captive, lest advantage be taken of his defenceless position. Moreover, he has to provide food for both. In various ways he is no longer, then, completely at liberty; and these worries adumbrate in a simple manner the universal truth that the instrumentalities by which the subordination of others is effected themselves subordinate the victor, the master, or the ruler.[91] Thus it comes that all nations attempting to live by conquest end by being themselves the victims of a military tyranny precisely similar to that which they hope to inflict; or, in other terms, that the attempt to impose by force of arms a disadvantageous commercial situation to the advantage of the conqueror ends in the conqueror's falling a victim to the very disadvantages from which he hoped by a process of spoliation to profit.
