[Traveling in Constantinople around 400 A.D. the Grecian philosopher] Synesius observes and deplores the fatal abuse which the imprudent bounty of the late emperor had introduced into the military service. The citizens and subjects had purchased an exemption from the indispensable duty of defending their country, which was supported by the arms of barbarian mercenaries.

In the same passage, Gibbon outlines Synesius' proposals to solve Rome's mercenary problem. Sixteen centuries later, in an America where "outsourcing war" has been called "an explosive trend," his ideas seem only slightly dated:

The measures which Synesius recommends are the dictates of a bold and generous patriot. He exhorts the emperor to revive the courage of his subjects by the example of manly virtue; to banish luxury from the court and from the camp; to substitute, in the place of the barbarian mercenaries, an army of men interested in the defence of their laws and of their property; to force, in such a moment of public danger, the mechanic from his shop and the philosopher from his school; to rouse the indolent citizen from his dream of pleasure; and to arm, for the protection of agriculture, the hands of the laborious husbandman.
