This work investigates the philosophical coherence of George Berkeley’s immaterialism by re-examining his core arguments regarding the nature of reality and perception. Kenneth P. Winkler, a scholar of early modern philosophy, utilizes a rigorous analytical framework to situate Berkeley’s radical claims within the context of 18th-century debates on abstraction and causality. By challenging traditional readings of Berkeley as a mere skeptic or idealist, Winkler argues that his conclusions regarding the non-existence of matter are logical outcomes of his specific reflections on representation and the nature of spirits.

Scholars frequently cite this text as a sophisticated and nuanced contribution to the study of Berkeley’s philosophy. It is widely regarded as a rigorous resource for students and academics seeking to understand the logical structure of immaterialist thought.
