Really? Start with the five hard questions. Then ask why norms, traditions, laws, values, institutions, always develop to enforce reciprocity under some variation given local constraints. Why are ploities, armies, empires created? Why do states and empires domesticate those who are not domesticated, and what is the means of doing it and why? Why is extermination so rare and conquest so nearly universal?
