The alternative of reason vs. force is the alternative of diplomacy vs. war. Now let's integrate diplomacy with some better known virtues. The first thing to do is to identify the social virtues. We must distinguish the virtues you would need even on a desert island from the virtues you need only among other men. Justice is clearly social.
Independence is hard to call.
We can recognize justice and honesty as sub-methods of diplomacy. To treat men justly and honestly is essential to winning and keeping their help. Diplomacy is the art of getting others to help. Rather, the aim of your diplomacy is your own good. Whatever friendships, alliances or arrangements you come to with others, can only be based on your own knowledge and purposes.
