"Soldiers are not as other men – that is the lesson that I have learned from a life cast among warriors. The lesson has taught me to view with extreme suspicion all theories and representations of war that equate it with any other activity in human affairs. War undoubtedly connects, as the theorists demonstrate, with economics and diplomacy and politics. Connection does not amount to identity or even similarity. War is wholly unlike diplomacy or politics because it must be fought by men whose values and skills are not those of politicians and diplomats. They are those of a world apart, a very ancient world, which exists in parallel with the everyday world but does not belong to it. Both worlds change over time, and the warrior world adapts in step to the civilian. It follows it, however, at a distance. The distance can never be closed, for the culture of the warrior can never be that of civilization itself. All civilisations owe their origins to the warrior; their cultures nurture the warriors who defend them, and the differences between them will make those of one very different in externals from those of another. It is, indeed, a theme of this book that in externals there are three distinct warrior traditions. Ultimately, however, there is only one warrior culture. Its evolution and transformation over time and place, from man’s beginnings to his arrival in the contemporary world, is the history of warfare."
