Ronald Weed's book offers a fresh investigation of political conflict in Aristotle's Politics. While there have been a number of studies on stasis or factional conflict, few provide a thorough analysis of its intractable character dimensions. Weed presents a highly original and provocative analysis of the moral psychology of factional conflict in the middle books of the Politics, arguing that the character deficiencies of a citizenry are the central causes of stasis and indispensable for understanding both the nature of these conflicts and their remedies. In Weed's view, Aristotle contends that stasis can be greatly limited without greatly reducing bad character, so long as the vices that breed it most are limited. Weed presents a novel and detailed explanation of how Aristotle's institutional remedies, such as the selective distribution of honor and wealth, may bypass circumstances that provoke stasis, if they account for what vices are triggered under those circumstances. Weed advances an understanding of Aristotle's practical thought that captures Aristotle's penetrating realism about political breakdown and pathology, while also preserving the robust and irreducible essence of his theory of character and rational choice.
