Fighting a War with a Moral Justification
兴兵开战要有正当的名义或理由。泛指做事有正当的理由。它包含两层意思：其一，师直为壮，谓出兵理由正当，则士气旺盛，战斗力强，否则难以服众；其二，无故不得兴兵，防止因贪、怒而穷兵黩武。其核心在于强调战争的正义性。这是文明精神的体现。
To wage a war, one must have a legitimate cause, just as we ought to have such a reason in doing all things. The term has two meanings. The first is that moral justification is a source of strength when waging a war. With moral justification, the troops will have high morale and strength in fighting. Without it, it would be difficult to command the troops. The second meaning is that war must not be waged without a just cause. Greed or anger should not be allowed to lead to militarism and aggression. The underlying notion of this concept is that war can only be fought with a just cause, which represents the spirit of civilization.
