Anti-philosophy is a tendency that dates back to Ancient Greece but came into circulation in the late 18th century as a technical term and gained strength in 20th-century Continental Philosophy. Movements such as structuralism/poststructuralism, deconstruction, and postmodernism have been influential in becoming important for anti-philosophy along with the developments in the philosophy of language. These tendencies nourish the anti-philosophy tradition by limiting the field of philosophy or declaring its end. Badiou declares that Nietzsche, whom he considers one of the most significant “events” in the history of thought, also plays a founder role in the construction of modern anti-philosophy and announces him the undisputed king of anti-philosophy. Badiou's denial of all anti-philosophical tendencies on the one hand, and his acceptance of an "event" by excluding Nietzsche from the mainstream of his thought on the other, becomes a critical and necessary philosophical agenda. With this study, we aim to comprehend the anti-philosophical character of Nietzsche's expression, which founds the claims of the closure of philosophy, and to examine Badiou's acceptance of it as an event of thought within the framework of the alternative for Philosophy of Event. The study can also be considered a first step attempt to assess the infrastructure of the anti-philosophy movement, which has a wide range of thoughts from Nietzsche to Lacan.
