War is a ritual, a deadly ritual, not the result of aggressive self-assertion, but of self-transcending identification. Without loyalty to tribe, church, flag or ideal, there would be no wars.
- Arthur Koestler
I’m not sure I completely agree with Koestler because there’s also something innate within us that is twisted for selfish power and dominance (our original sin), but he has a point. Few would argue that the rituals used to wage war change with the times, but students of Clausewitz are skeptical about supposed changes in what we believe to be war’s enduring nature. According to the Prussian, war’s nature does not change - only its character. The way we use these words today can seem to render such a distinction meaningless, but careful attention to semantics can reveal real problems in how we think about war, society, and the future.
The nature of war describes its unchanging essence: that is, those things that differentiate war (as a type of phenomenon) from other things. War’s nature is violent, interactive, and fundamentally political. Absent any of these elements, what you’re talking about is not war but something else.
The character of war describes the changing way that war as a phenomenon manifests in the real world. As war is a political act that takes place in and among societies, its specific character will be shaped by the politics and culture of those societies - by what Clausewitz called the “spirit of the age.”
War’s conduct is undoubtedly influenced by technology, law, ethics, culture, methods of social, political, and military organisation, and other factors that change across time and place.
