This book investigates the philosophical and theological framework of John Norris to determine his significance within the intellectual landscape of the late 17th century. W. J. Mander, a scholar of British philosophy, utilizes primary texts and historical context to reconstruct Norris's unique synthesis of Augustinian, Platonic, and Cartesian ideas. The work argues that Norris occupies a critical position as both a bridge between continental rationalism and British empiricism and as a primary antagonist to the burgeoning Lockean tradition.

Scholars recognize this text as a necessary intervention in the study of neglected early modern thinkers. Readers frequently note the academic density of the prose, which is intended for those with a background in philosophical history.
