Kevin Killeen's study of the seventeenth-century author Thomas Browne is a welcome contribution to a number of fields of early modern scholarship. Focusing on Browne's encyclopedic study of error, the Pseudodoxia Epidemica (1646), Killeen places Browne in his intellectual and political contexts, and in doing so illuminates a number of overlooked dimensions of Browne's thought. Chapter 4, for example, explores Pseudodoxia's extensive interaction with the seventeenth-century practices of natural knowledge, and specifically with the way in which Browne envisions “a substantial religious and indeed scriptural framework to his science” (112). This is evident in Browne's attention to the problem of action at a distance. He put forward a theological basis for the theory of effluvia (the mechanisms for unseen action), for example. Although he was not a particularly original natural philosophical thinker, Browne's ability to weave together various models of natural knowledge within an overarching scriptural framework Killeen argues, makes his work intriguing. These disciplinary amalgams reveal that, despite what has often been assumed, Browne was no mere popularizer of knowledge. (112) Meticulously researched and carefully argued, Killeen's book will prompt a reassessment of Browne's work, as well as pave the way for renewed attention to Browne by scholars of the intellectual, political and religious climate of seventeenth century England.
