Theory and Practice is a series of nine lectures that Jacques Derrida delivered at the École Normale Supérieure in 1976 and 1977. The topic of “theory and practice” was associated above all with Marxist discourse and particularly the influential interpretation of Marx by Louis Althusser. Derrida’s many questions to Althusser and other thinkers aim at unsettling the distinction between thinking and acting.
Derrida’s investigations set out from Marx’s “Theses on Feuerbach,” in particular the eleventh thesis, which has often been taken as a mantra for the “end of philosophy,” to be brought about by Marxist practice. Derrida argues, however, that Althusser has no such end in view and that his discourse remains resolutely philosophical, even as it promotes the theory/practice pair as primary values. This seminar also draws fascinating connections between Marxist thought and Heidegger and features Derrida’s signature reconsideration of the dichotomy between doing and thinking. This text, available for the first time in English, shows that Derrida was doing important work on Marx long before Specters of Marx. As with the other volumes in this series, it gives readers an unparalleled glimpse into Derrida’s thinking at its best—spontaneous, unpredictable, and groundbreaking.
Jacques Derrida was a French philosopher best known for developing deconstruction, a method of critical analysis that questioned the stability of meaning in language, texts, and Western metaphysical thought. Born in Algeria, he studied at the École Normale Supérieure in Paris, where he was influenced by philosophers such as Heidegger, Husserl, and Levinas. His groundbreaking works, including Of Grammatology (1967), Writing and Difference (1967), and Speech and Phenomena (1967), positioned him at the center of intellectual debates on language, meaning, and interpretation. Derrida argued that Western philosophy was structured around binary oppositions—such as speech over writing, presence over absence, or reason over emotion—that falsely privileged one term over the other. He introduced the concept of différance, which suggests that meaning is constantly deferred and never fully present, destabilizing the idea of fixed truth. His work engaged with a wide range of disciplines, including literature, psychoanalysis, political theory, and law, challenging conventional ways of thinking and interpretation. Throughout his career, Derrida continued to explore ethical and political questions, particularly in works such as Specters of Marx (1993) and The Politics of Friendship (1994), which addressed democracy, justice, and responsibility. He held academic positions at institutions such as the École des Hautes Études en Sciences Sociales and the University of California, Irvine, and remained an influential figure in both European and American intellectual circles. Despite criticism for his complex writing style and abstract concepts, Derrida’s ideas have left a lasting impact on contemporary philosophy, literary theory, and cultural criticism, reshaping the way meaning and language are understood in the modern world.
