All of these factors can be readily measured. Understanding one's part in the shared burden. Measurement seeks to limit data so that it can be examined in accordance with some qualitative or quantitative standard. Except by making heroic assumptions, much of warfare cannot be measured directly on a ratio scale. We are, therefore, required either to make such assumptions, or to provide surrogates for what we cannot measure directly in order to wrench them onto the ratio scale where they can be manipulated.
