In Spinoza's Argument for Substance Monism: Why There Is Only One Thing, Christopher Martin deploys the notion of conceptual independence and the principle of sufficient reason in development of a distinctive critical analysis of Spinoza's argument for substance monism that engagingly unfurls the complexity, audacity, and grandeur of Spinoza's thought.

Martin's book is simultaneously a lucid introduction to Spinoza's metaphysics and an exciting contribution to the scholarship on Spinoza's substance monism. The core of this book is a compelling reconstruction and defense of Spinoza's argument that there is only one fundamental being in the cosmos. Yet it is also a testament to the enduring power of Spinoza's philosophical method. Martin makes a forceful case for treating Spinoza's ideas not merely as relics of the history of thought, but as philosophical possibilities that we must contend with even today.

In this valuable book, Martin brings a clear voice and vision to one of the most vexing arguments in seventeenth-century philosophy. Balancing a conversational tone with deep knowledge of the historic and scholarly context, Martin methodically lays out, explains, and defends Spinoza's argument for substance monism. As he proceeds, Martin considers tricky concepts and arguments in sophisticated, but accessible, ways that will be of interest to both students and specialists. Spinoza's Argument for Substance Monism is an excellent resource for understanding this component of Spinoza's philosophical system and might just convince you that there is only one substance.

Christopher Martin's remarkably lucid book gives anyone curious about Spinoza's Ethics the background needed to appreciate some of the most important arguments in that famously forbidding work. I will enthusiastically recommend it to all my students and will be giving it to family members who have been wondering for years what I spend a lot of my time thinking about.
