Short Comment on Melissa Lane’s Popular Sovereignty Paper Paul Sagar Professor Lane’s paper offered a fascinating approach to conceptualising both Ancient Greek political thought and our own conceptions of popular sovereignty. Through innovative readings of Aristotle and Plato, she urged us to think about how sovereignty can be understood through political offices, and not merely the individuals who hold them. Yet any discussion of the Greeks in the context of popular sovereignty immediately invites caution, simply because the Greeks lacked that concept for themselves. Professor Lane’s paper encourages us to understand the Greek kurios as roughly equivalent to our concept of ‘authority’. This is important. The modern concept of ‘sovereignty’ is umbilically linked to questions of ‘authority’, and also of ‘legitimacy’ (another concept arguably lacked by the Greeks). This is because sovereignty theory is in significant measure justification theory: it seeks to explain not only who has (or should have) ultimate political decision-making power, but more fundamentally who has (or should have) the legitimate authority to exercise that power, and thus rightfully coerce others. A theory of sovereignty thus needs an account of authority. But it is at least arguable that the Greek’s lacked any such concept. Kurios is only controversially rendered ‘authority’; it could also be rendered as pertaining to mastery and lordship, and the possession of powers of ownership. On this understanding, lacking a concept of authority the Greeks would also seem to lack a concept of modern sovereignty. Why is this significant? What is wrong with retrospectively supplying the Ancients with modern conceptualisations that render their thought more perspicuous and comprehensible? Perhaps nothing. But we should bear in mind the warnings of thinkers such as Friedrich Nietzsche, and in his shadow Bernard Williams and Alistair MacIntyre. That rather than improving the thought of the Ancients, we may be failing to appreciate when they were better off than we are now. Consider a (for now) necessarily speculative possibility. Let us suppose that sovereignty theory is a post-Roman, European Christendom phenomenon. The Greeks necessarily lacked it. But who says they were worse off for lacking it? Perhaps they show us that, at the very least, sovereignty theory is surplus to political requirements for a functioning society. Perhaps they show us more: that sovereignty theory is acquired baggage from a Christian era that we are now moving out of, and would actually be better off without. Rather than giving the Greeks our supposedly improved concepts, maybe the lesson should run in the other direction. I should stress that I do not wish to claim that this is definitely so. But I do suggest that in dealing with the Ancients, we always keep in mind the possibility that it might be so.
