Liberty, Conscience, and Toleration is a masterful achievement, one as remarkable for its careful treatment and painstaking analysis of early modern toleration and liberty of conscience as for its insightful reflections on political theory, practice and genre. Assessing the wide sweep of Penn's writings and actions serves as an exemplary opportunity not only to reflect on theory and its complex and at times unexpected relationship to practice but also to see more clearly the ways in which political theorizing responds to context, shapes the embodied and performative dimensions of protest and resistance, resists entrenched and coercive power, and protects religion, prudence and civil interest.
