Peaceful disputes are maintained when men sincerely believe that they are morally, logically correct about the issues at hand. It is when neither side is really certain that wars are instigated.
Women particularly should concern themselves with peace because men by nature are more foolhardy and headstrong, and their overwhelming desire to avenge themselves prevents them from foreseeing the resulting dangers and terrors of war. But woman by nature is more gentle and circumspect. Therefore, if she has sufficient will and wisdom she can provide the best possible means to pacify man.
Sometimes we have to soak ourselves in the tears and fears of the past to water our future gardens.
