The article introduces a symposium, “The Crowd in the History of Political Thought,” which is being published as a two-part special issue. The articles are by American and European scholars with disparate interests and approaches to the history of political thought. Some engage contemporary questions, while others offer interpretive analyses. Today, commentators, scholars, and pundits alike ignore the history of political thought to the detriment of their understanding of populism. Many thinkers have reflected on democratic health and sickness. The articles here furnish a partial catalog of the quarrels associated with this inherited vocabulary. The tradition itself is best conceived of as an unfinished Socratic conversation. In this issue, articles on Thucydides, Aristophanes, Plato, and Aristotle orbit the original democracy at Athens, the backdrop for reflections on popular rule of so many thinkers. The final article on Josephus moves away from the experience of the Greek polis toward the more contemporary preoccupations of the second issue.
