Book excerpt: The Revolution of the Saints is a study, both historical and sociological, of the radical political response of the Puritans to disorder. It interprets and analyzes Calvinism as the first modern expression of an unremitting determination to transform on the basis of an ideology the existing political and moral order. Michael Walzer examines in detail the circumstances and ideological options of the Puritan intelligentsia and gentry. He sees Puritanism, in sharp contrast to some generally accepted views, as the political theory of intellectuals and gentlemen attempting to create a new government and society.
