The motivating principle of human survival, based upon the instinctual needs of food and sex, is power. The ability to effectively use power is crucial for the sustenance of life itself. The technology of fighting, pre-modern and modern, is an expression of this power, and the human race has survived to this point in history because of the ability to properly use this power. In fact, the development of this technology has given rise to new ideas, scientific advances, civilization, and culture. The basic principle of power is deeply rooted in life itself, and it is still the basis of human society as we know it today.
