Engaging with the challenging and controversial reading of Spinoza presented by Gilles Deleuze in Expressionism in Philosophy (1968), this book focuses on Deleuze's redeployment of Spinozist concepts within the context of his own philosophical project of constructing a philosophy of difference as an alternative to the Hegelian dialectical philosophy. Duffy demonstrates that a thorough understanding of Deleuze's Spinozism is necessary in order to fully engage with Deleuze's philosophy of difference.

Gilles Deleuze's engagements with mathematics, replete in his work, rely upon the construction of alternative lineages in the history of mathematics, which challenge some of the self imposed limits that regulate the canonical concepts of the discipline. For Deleuze, these challenges provide an opportunity to reconfigure particular philosophical problems - for example, the problem of individuation - and to develop new concepts in response to them. The highly original research presented in this book explores the mathematical construction of Deleuze's philosophy, as well as addressing the undervalued and often neglected question of the mathematical thinkers who influenced his work. In the wake of Alain Badiou's recent and seemingly devastating attack on the way the relation between mathematics and philosophy is configured in Deleuze's work, Simon B.Duffy offers a robust defence of the structure of Deleuze's philosophy and, in particular, the adequacy of the mathematical problems used in its construction. By reconciling Badiou and Deleuze's seemingly incompatible engagements with mathematics, Duffy succeeds in presenting a solid foundation for Deleuze's philosophy, rebuffing the recent challenges against it.

This title presents a range of critical engagements with the work of Alain Badiou. This collection of 13 essays directly addresses the work of Alain Badiou, focusing specifically on the philosophical content of his work and the various connections he established with both his contemporaries and his philosophical heritage. This is the first reassessment of Badiou's work since the publication of the English translation of Logics of Worlds, (2009). It critiques how Badiou sources and responds to existing philosophical arguments and traditions as well as the arguments he employs to do so. It examines Badiou's work through the lens of a number of thinkers and themes, from Cantor and category/topos theory, through Lacan and Lautman, to Sartre and subject.

This is the first English collection of the work of Albert Lautman, a major figure in philosophy of mathematics and a key influence on Badiou and Deleuze. Albert Lautman (1908-1944) was a French philosopher of mathematics whose work played a crucial role in the history of contemporary French philosophy. His ideas have had an enormous influence on key contemporary thinkers including Gilles Deleuze and Alain Badiou, for whom he is a major touchstone in the development of their own engagements with mathematics. "Mathematics, Ideas and the Physical Real" presents the first English translation of Lautman's published works between 1933 and his death in 1944. Rather than being preoccupied with the relation of mathematics to logic or with the problems of foundation, which have dominated philosophical reflection on mathematics, Lautman undertakes to develop an understanding of the broader structure of mathematics and its evolution. The two powerful ideas that are constants throughout his work, and which have dominated subsequent developments in mathematics, are the concept of mathematical structure and the idea of the essential unity underlying the apparent multiplicity of mathematical disciplines. This collection of his major writings offers readers a much-needed insight into his influence on the development of mathematics and philosophy.

What does it mean to think about, and with, Spinoza today? This collection, the first broadly interdisciplinary volume dealing with Spinozan thought, asserts the importance of Spinoza’s philosophy of immanence for contemporary cultural and philosophical debates. Engaging with Spinoza’s insistence on the centrality of the passions as the site of the creative and productive forces shaping society, this collection critiques the impulse to transcendence and regimes of mastery, exposing universal values as illusory. Spinoza Now pursues Spinoza’s challenge to abandon the temptation to think through the prism of death in order to arrive at a truly liberatory notion of freedom. In this bold endeavor, the essays gathered here extend the Spinozan project beyond the disciplinary boundaries of philosophy to encompass all forms of life-affirming activity, including the arts and literature. The essays, taken together, suggest that “Spinoza now” is not so much a statement about a “truth” that Spinoza’s writings can reveal to us in our present situation. It is, rather, the injunction to adhere to the attitude that affirms both necessity and impossibility.
