“Matysik has written a thoughtful, deeply researched, and elegantly structured intellectual history that fastens our attention on certain key chapters in the European reception of Spinoza’s philosophy. When Spinoza Met Marx is an excellent book, and it deserves considerable attention from readers in modern European intellectual history and from anyone interested in the modern fortunes of Marxism and posthumanist social theory.”
— Peter E. Gordon, coauthor of 'Authoritarianism: Three Inquiries in Critical Theory'
“When Spinoza Met Marx is essential reading. It fills a gap in the history of European Spinozism, and it provides a new context for the histories of Marxism and socialism—one that it is crucial to understand as scholars and political actors seek to adapt Marxist frameworks to ongoing matters of social and environmental justice. It also provides a new intellectual history of nineteenth-century German political thought that is truly innovative in its approach.”
— Knox Peden, author of 'Spinoza Contra Phenomenology: French Rationalism from Cavaillès to Deleuze'
"Matysik’s writing is very clear and free of jargon. The book is well organized and extensively documented with more than 80 pages of endnotes and bibliography. There is a thoughtfully constructed index."

"This is a book of superlatives: the most comprehensive, most detailed, most ambitious, simply the best thing ever written in any language on the Marx-Spinoza connection in the long nineteenth century. Masterfully composed and brilliantly researched, the volume accomplishes a herculean task in surveying the historical, philosophical and political reception of Spinoza in that time period."
