Although he proclaims Hegel as his ultimate hero, iek, the most popular philosopher of our time, has a mode much closer to Nietzsche. Hegel's work is all about ancient labor, Nietzsche's is all about modern dancing. Žižek philosophizes like a dancer, and he writes the way he talks: fast and funny. You almost never understand how all his thoughts fit together, but you are always entertained by the way he picks up this or that thing, analyzes it, and then drops it.
