Without a theory the facts are silent, the economist F. A. Hayek has written. That may be true of the cold facts of economics, but the facts of war are not cold. They burn with the heat of the fires of hell. The late Sir John Keegan, the renowned military historian known for The Face of Battle and many other superb studies of combat in the Western world, opposed philosophical abstraction. Theories of history that sought to explain the causes of conflict by reference to materialist, idealist, gender, (what have you) theory failed to appreciate the role human agency and culture — tradition, religion, tribal identity — played in explaining human action, Keegan believed.
In his particular field of study, military history, Keegan believed the theories of Carl von Clausewitz that war is about politics, was a wholly inadequate explanation. (War is simply [an expression] of political intercourse, with the addition of other means. Clausewitz, On War, p.605) The adoption of theoretical constructs to explain war, Keegan argued, lay upon totalizing or universalist assumptions that failed to see farther than their cultural presuppositions.
Journalism suffers from these problems. What I see as the displacement of the classical Anglo-American school of journalism by European-style advocacy journalism mirrors the failings Keegan identified in the historical profession. Reporters who come to a story through advocacy journalism have a preconceived notions about the nature of truth into which they seek to place the available facts. If the facts are inconvenient or do not fit the theories, they can be left out of the story.
