Weapons are unhappy tools, not chosen by thoughtful people, to be used only when there is no choice, and with a calm, still mind, without enjoyment. To enjoy using weapons is to enjoy killing people, and to enjoy killing people is to lose your share in the common good. It is right that the murder of many people be mourned and lamented. It is right that a victor in war be received with funeral ceremonies.
