War is also a cultural entity, and its practice is not linked to any single type of political organisation or society. Rather, as discussed by John Keegan in his “History Of Warfare”, war is a universal phenomenon whose form and scope is defined by the society that wages it. The conduct of war extends along a continuum, from the almost universal tribal warfare that began well before recorded human history, to wars between city states, nations, or empires.
Psychologists such as E.F.M. Durban and John Bowlby have argued that human beings are inherently violent. While this violence is repressed in normal society, it needs the occasional outlet provided by war. This mixes with other notions such as displacement, where a person transfers their grievances into bias and hatred against other ethnic groups, racial groups, religions, nations or ideologies. While these theories may have some explanatory value about why wars occur, they do not explain when or how they occur. Nor do they explain the existence of certain human cultures completely devoid of war.[10] If the innate psychology of the human mind is unchanging, these variations are inconsistent. A solution adapted to this problem by militarists such as Franz Alexander is that peace does not really exist. Periods that are seen as peaceful are actually periods of preparation for a later war or when war is suppressed by a state of great power, such as the Pax Britannica.
If war is innate to human nature, as is presupposed and predetermined (according to determinism philosophy) by many psychological theories, then there is little hope of ever escaping it. Psychologists have argued that while human temperament allows wars to occur, this only happens when mentally unbalanced people are in control of a nation. This school of thought argues leaders that seek war such as Napoleon, Hitler, Saddam Hussein, and Stalin were mentally abnormal, but fails to explain the thousands of free and presumably sane people who wage...
