Galba

Iphicrates the Athenian used to think that the mercenary soldier might well be fond of wealth and fond of pleasure, in order that his quest for the means to gratify his desires might lead him to fight with greater recklessness; but most people think that a body of soldiers, just like a natural body in full vigour, ought to have no initiative of its own, but should follow that of its commander.

Wherefore Paulus Aemilius, as we are told, finding that the army which he had taken over in Macedonia was infected with loquacity and meddlesomeness, as though they were all generals, gave out word that each man was to have his hand ready and his sword sharp, but that he himself would look out for the rest.[*](See the Aemilius, xiii. 4.)

Moreover, Plato[*](Cf. e.g. Republic 376 C.) sees that a good commander or general can do nothing unless his army is amenable and loyal; and he thinks that the quality of obedience, like the quality characteristic of a king, requires a noble nature and a philosophic training, which, above all things, blends harmoniously the qualities of gentleness and humanity with those of high courage and aggressiveness. Many dire events, and particularly those which befell the Romans after the death of Nero, bear witness to this, and show plainly that an empire has nothing more fearful to show than a military force given over to untrained and unreasoning impulses.
