This book investigates how René Descartes’ metaphysical framework accounts for the existence and nature of everyday objects and the mundane experiences of human life. Deborah J. Brown and Calvin G. Normore, both established scholars in early modern philosophy, utilize a rigorous analytical approach to examine Cartesian texts. They argue that Descartes’ ontology is not merely a system of abstract substances but a structured attempt to reconcile the mechanical philosophy with the common-sense reality of the world.

Experts in early modern philosophy recognize this work as a significant contribution to the study of Cartesian metaphysics. Readers frequently note the academic density of the prose, which is intended for advanced students and scholars of the field.
