The oeuvre of Alain Badiou has gained international success and recognition, but most of the secondary literature focuses on internal problems of Badiou's philosophy, rather than its position within a broader philosophical genealogy. This book unites philosophers from Germany, Slovenia, the UK, Australia and France, to trace the relation between elements of Badiou's philosophy and the German philosophical tradition, namely the three significant movements of German Idealism, Phenomenology, Marxism and the Frankfurt School. This is a discussion that has not yet been established, although the parallels and decisive differences between poststructuralist French philosophy and German philosophy are apparent. Through these paradigms - Badiou's reception of German Idealism, Marxism, Adorno and the Critical Theory, and Heideggerian phenomenology - the authors shed light onto Badiou's inheritance of and engagement with these specific traditions, but also highlight the links between these philosophies to open up new questions for contemporary continental thought. With an original chapter from Alain Badiou himself, looking back at his influences and antagonisms within the German tradition, this book is essential for readers interested in the exploration of Badiou's legacy. It illustrates the continuation of poststructuralist philosophy, Critical Theory and the Frankfurt School, assessing the place of classic continental philosophy to tackle how we might benefit from these intellectual exchanges today.
