" I hold that it is bad, as far as we are concerned, if a person opposed
to a party, an army, or a school is not attacked by the enemy. For in
that case, it would mean that we have sunk to the level of the enemy.
It is good if we are attacked by the enemy. This proves that we have
drawn a clear line of demarcation between the enemy and ourselves.
It is still better if the enemy attacks us wildly, and takes us as utterly
black and without a single virtue. It demonstrates that we have not
only drawn a clear line of demarcation between the enemy and
ourselves, but achieved a great deal in our work." Sun Tzu
