French philosopher Jean Baudrillard, a social theorist known for his acerbic commentaries on consumerism and excess, died Tuesday, his publishing house said. He was 77. Baudrillard died at his home in Paris, said Michel Delorme of the Galilee publishing house. He died after a "long illness," Delorme said, a term that in France most often means cancer. The two men had worked together since 1977, when "Oublier Foucault" (Forget Foucault), one of some 20 books written by Baudrillard, was published, Delorme said by telephone. The last book published by Baudrillard was "Cool Memories V," in 2005.
