Gilles Deleuze produced a body of work that challenged traditional metaphysical views by asserting that identity is a secondary effect of difference. Active from the early 1950s until 1995, the French thinker navigated the landscapes of ontology, aesthetics, and social critique, leaving a substantial legacy in the fields of continental philosophy and post-structuralism through his prolific writing.
Academic Formation and Early Career
Born in 1925 in the 17th arrondissement of Paris, Deleuze attended Lycée Carnot and later Lycée Louis-le-Grand. His formative years were marked by the occupation of France, during which his brother, Georges, died while in transit to a concentration camp. In 1944, he began studies at the Sorbonne, learning under influential figures such as Georges Canguilhem and Jean Hyppolite. After passing his agrégation in 1948, he held teaching roles at various lycées before transitioning to university positions. He served as a research fellow at the National Center for Scientific Research from 1960 to 1964 and taught at the University of Lyon until 1969.

Deleuze challenged the standard philosophical hierarchy where identity takes precedence over difference. He argued that identities are instead generated by underlying differences. In his 1968 doctoral dissertation, published as Difference and Repetition, he explored this ontological reversal. He rejected the notion that categories and forms exist independently, proposing that reality must be grasped as it is, through internal differences. His approach to space and time diverged from Kantian traditions, positioning his concepts of the virtual as conditions for actual experience rather than transcendent models.
Collaborations and Later Years
In 1969, Deleuze joined the experimental Paris 8 University, where he remained until his retirement in 1987. During this period, his collaboration with Félix Guattari resulted in significant texts, including Anti-Oedipus (1972) and A Thousand Plateaus (1980). Beyond his original treatises, he published numerous monographs examining the history of philosophy and art, covering thinkers like Spinoza, Leibniz, Nietzsche, and Bergson, as well as artists such as Francis Bacon and Marcel Proust. His final years were defined by severe respiratory illness exacerbated by tuberculosis, leading to his suicide in 1995 in his native Paris.
