When we consider the nature and the objects of the ambitions and desires that the statesman or leader must fulfill, we see why the relations of ruler to people are difficult to understand. Nations do not know with clearness either what they desire or why at heart they desire the objectives that seem of most importance. People give economic and political reasons, but the consciousness of nations is subject to deep moods, and is influenced by remote events and traditions. Nations have generic desires as well as specific ones. They always crave empire; they all desire to have rank. They are always ambitious, jealous and watchful of one another. These general and more or less subconscious desires make their desires for specific objects intense, but they also make them peculiarly irrational. The heroic examples of history, hereditary emotions and the effects of specific events in the history of peoples complicate their politics, and often make rational politics impossible. Nations will not act in their own best interests, because they are governed by irrational motives. In this way certain disparities are often produced between the people and their practical statesmen, but history seems to show us that when these disparities exist in the region of fundamental desires and policies it is the leader who must yield. History seems to show us also that wars, coming in general out of the deeper motives of nations, do not belong to such an extent as is often supposed to the realm of politics. Political causes are often incidental causes and determine the time and place of wars but do not create them. Cramb (66) says that wars persist in spite of their unreason, because there is something transcendental that supports them, and this transcendental purpose is the desire for empire. Powers (75) says that nations fight for tangible things and also for intangible things. The tangible things are existence, commerce, independence, territory; nations also desire objects that are not useful, the worth of which consists in their satisfaction of taste. The ambition to own colonies, Powers thinks, is of this nature. Colonies are quite as much ornamental as they are useful. They convey the feeling and impression of power. That these deep desires of nations as expressed in the ambition to reach certain geographical objectives are exceedingly strong, often if not always irrational, brutally arrogant and tenacious, the whole course of history teaches us. These desires are indeed the forces behind historical movements. They create politics and policies. War preexists in these irrational purposes. These purposes are charged with emotion, with prejudice, and tradition. It is with these motives that all practical politics must contend, and these motives are the forces that the statesman must use and make more rational.
