On making prisoners of our generals, they expected that we should perish from want of direction and order. It is incumbent, therefore, on our present… - Xenophon

The company, then, were feasting in silence, as though some one in authority had commanded them to do so, when Philip the buffoon knocked at the door and told the porter to announce who he was and that he desired to be admitted; he added that with regard to food he had come all prepared, in all varieties—to dine on some other person's,—and that his servant was in great distress with the load he carried of—nothing, and with having an empty stomach. Hearing this, Callias said, “Well, gentlemen, we cannot decently begrudge him at the least the shelter of our roof; so let him come in.” With the words he cast a glance at Autolycus, obviously trying to make out what he had thought of the pleasantry. But Philip, standing at the threshold of the men's hall where the banquet was served, announced: “You all know that I am a jester; and so I have come here with a will, thinking it more of a joke to come to your dinner uninvited than to come by invitation.” “Well, then,” said Callias, “take a place; for the guests, though well fed, as you observe, on seriousness, are perhaps rather ill supplied with laughter.”

Righteously and honourably he would obtain them, if he might, or else forego them.

That ... is the road to the obedience of compulsion. But there is a shorter way to a nobler goal, the obedience of the will. When the interests of mankind are at stake, they will obey with joy the man whom they believe to be wiser than themselves. You may prove this on all sides: you may see how the sick man will beg the doctor to tell him what he ought to do, how a whole ship’s company will listen to the pilot.
