Spinoza's theoretical philosophy is one of the most radical attempts to construct a pure ontology with a single infinite substance. This book, which presents Spinoza's main ideas in dictionary form, has as its subject the opposition between ethics and morality, and the link between ethical and ontological propositions. His ethics is an ethology, rather than a moral science. Attention has been drawn to Spinoza by deep ecologists such as Arne Naess, the Norwegian philosopher; and this reading of Spinoza by Deleuze lends itself to a radical ecological ethic. As Robert Hurley says in his introduction, "Deleuze opens us to the idea that the elements of the different individuals we compose may be nonhuman within us. One wonders, finally, whether Man might be defined as a territory, a set of boundaries, a limit on existence." Gilles Deleuze, known for his inquiries into desire, language, politics, and power, finds a kinship between Spinoza and Nietzsche. He writes, ""Spinoza did not believe in hope or even in courage; he believed only in joy and in vision . . . he more than any other gave me the feeling of a gust of air from behind each time I read him, of a witch's broom that he makes one mount. Gilles Deleuze was a professor of philosophy at the University of Paris at Vincennes. Robert Hurley is the translator of Michel Foucault's History of Sexuality.

Expressionism, Deleuze's philosophical commentary on Spinoza, is a critically important work because its conclusions provide the foundations for Deleuze's later metaphysical speculations on the nature of power, the body, difference and singularities. Deleuze and Spinoza is the first book to examine Deleuze's philosophical assessment of Spinoza and appraise his arguments concerning the Absolute, the philosophy of mind, epistemology and moral and political philosophy. The author respects and disagrees with Deleuze the philosopher and suggests that his arguments not only lead to eliminativism and an Hobbesian politics but that they also cast a mystifying spell.

In this remarkable work, Gilles Deleuze, the renowned French philosopher, reflects on one of the thinkers of the past who most influenced his own sweeping reconfiguration of the tasks of philosophy. For Deleuze, Spinoza, along with Nietzsche and Lucretius, conceived of philosophy as an enterprise of liberation and radical demystification. He locates in Spinoza “a set of affects, a kinetic determination, an impulse” and makes Spinoza into “an encounter, a passion.” Expressionism in Philosophy was the culmination of a series of monographic studies by Deleuze (on Hume, Bergson, Nietzsche, Proust, Kant, and Sacher-Masoch) and prepared the transition from these abstract treatments of historical schemes of experience to the nomadology of Capitalism and Schizophrenia (Anti-Oedipus and A Thousand Plateaus, co-authored with Félix Guattari). Thus, Expressionism in Philosophy is both a pivotal reading of Spinoza’s work and a crucial text within the development of Deleuze’s thought.

Spinoza Contra Phenomenology fundamentally recasts the history of postwar French thought, typically presumed to have been driven by a critique of reason indebted to Nietzsche and Heidegger. Although the reception of phenomenology gave rise to many innovative developments in French philosophy, from existentialism to deconstruction, not everyone in France was pleased with this German import. This book recounts how a series of French philosophers used Spinoza to erect a bulwark against the nominally irrationalist tendencies of phenomenology. From its beginnings in the interwar years, this rationalism would prove foundational for Althusser's rethinking of Marxism and Deleuze's ambitious metaphysics. There has been a renewed enthusiasm for Spinozism of late by those who see his work as a kind of neo-vitalism or philosophy of life and affect. Peden counters this trend by tracking a decisive and neglected aspect of Spinoza's philosophy—his rationalism—in a body of thought too often presumed to have rejected reason. In the process, he demonstrates that the virtues of Spinoza's rationalism have yet to be exhausted.

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.

Beth Lord looks at Kant's philosophy in relation to four thinkers who attempted to fuse transcendental idealism with Spinoza's doctrine of immanence. Examining Jacobi, Herder, Maimon and Deleuze, Lord argues that Spinozism is central to the development of Kant's thought, and opens new avenues for understanding Kant's relation to Deleuze.
