Since opposed principles, or ideologies, are irreconcilable, wars fought over principle will be wars of mutual annihilation. But wars fought for simple greed will be far less destructive, because the aggressor will be careful not to destroy what he is fighting to capture. Reasonable - that is, human - men will always be capable of compromise, but men who have dehumanized themselves by becoming the blind worshipers of an idea or an ideal are fanatics whose devotion to abstractions makes them the enemies of life.
