The despotic imperative: From Hiero to the circle
Authors:
Publisher and Date:(Duke University Press, 2019)The article thematizes the actuality of despotism through a double reading of Xenophon’s Hiero and Dave Eggers’s Circle. A key text on despotism, Hiero is interesting to reconsider in a contemporary context because of its explicit focus on the economic element in the nexus of despotism, economy, and voluntary servitude. Discussing this nexus in an ancient context, the article turns to The Circle, a dystopic novel from 2013, which elaborates on how the attempt at creating a transparent society ...
