Yet it was long a subject of dispute among mankind, whether military efforts were more advanced by strength of body, or by force of intellect. For, in affairs of war, it is necessary to plan before beginning to act, and, after planning, to act with promptitude and vigor. Thus, each being insufficient of itself, the one requires the assistance of the other.
II. In early times, accordingly, kings (for that was the first title of sovereignty in the world) applied themselves in different ways; some exercised the mind, others the body. At that period, however, the life of man was passed without covetousness; every one was satisfied with his own. But after Cyrus in Asia and the Lacedaemonians and Athenians in Greece, began to subjugate cities and nations, to deem the lust of dominion a reason for war, and to imagine the greatest glory to be in the most extensive empire, it was then at length discovered, by proof and experience, that mental power has the greatest effect in military operations. And, indeed, if the intellectual ability of kings and magistrates were exerted to the same degree in peace as in war, human affairs would be more orderly and settled, and you would not see governments shifted from hand to hand, and things universally changed and confused. For dominion is easily secured by those qualities by which it was at first obtained. But when sloth has introduced itself in the place of industry, and covetousness and pride in that of moderation and equity, the fortune of a state is altered together with its morals; and thus authority is always transferred from the less to the more deserving.
