As this dystopian election campaign has unfolded, my mind keeps being tugged by a passage in Plato’s Republic. It has unsettled — even surprised — me from the moment I first read it in graduate school. The passage is from the part of the dialogue where Socrates and his friends are talking about the nature of different political systems, how they change over time, and how one can slowly evolve into another. And Socrates seemed pretty clear on one sobering point: that “tyranny is probably established out of no other regime than democracy.” What did Plato mean by that? Democracy, for him, I discovered, was a political system of maximal freedom and equality, where every lifestyle is allowed and public offices are filled by a lottery. And the longer a democracy lasted, Plato argued, the more democratic it would become. Its freedoms would multiply; its equality spread. Deference to any sort of authority would wither; tolerance of any kind of inequality would come under intense threat; and multiculturalism and sexual freedom would create a city or a country like “a many-colored cloak decorated in all hues.”

This rainbow-flag polity, Plato argues, is, for many people, the fairest of regimes. The freedom in that democracy has to be experienced to be believed — with shame and privilege in particular emerging over time as anathema. But it is inherently unstable. As the authority of elites fades, as Establishment values cede to popular ones, views and identities can become so magnificently diverse as to be mutually uncomprehending. And when all the barriers to equality, formal and informal, have been removed; when everyone is equal; when elites are despised and full license is established to do “whatever one wants,” you arrive at what might be called late-stage democracy. There is no kowtowing to authority here, let alone to political experience or expertise.
