Although England is the focus of attention for most of the contributors, their themes have wider significance. Among the topics covered in the collection are the political thought of the Levellers and of James Harrington; radical social movements of the Puritan Revolution; the ideological context of physiological theories associated with William Harvey; the relationship between science and religion and the social relations of science; and the function of millenariansim and eschatology in the seventeenth century. The editor’s Introduction indicates the context in which the articles were composed and provides valuable bibliographical information about the subjects discussed.
