[I]
THE GOVERNMENT OF A COUNTRY

And Wu the Master said:—

The mighty rulers of old first trained their retainers, and then extended their regard to their outlying feudatories.

There are four discords:—

Discord in the state: then never make war.

Discord in the army: then do not strike camp.

Discord in the camp: then do not advance to attack.

Discord in the battle array: then seek not to decide the issue.
