He is recognized for his scholarship on continental philosophy and phenomenology. He has published extensively on philosophy's roots in political and religious disappointment, as well as on contemporary art, poetry, fashion, political theory, and authenticity as they relate to philosophy. He regularly contributes to The Guardian and moderates "The Stone," a New York Times series that features contemporary philosophers' writings on issues that include art, war, ethics, gender and popular culture. He is also the "Chief Philosopher" of the International Necronautical Society, a parody of early 20th century avant-garde organizations.
