José Carlos Mariátegui is recognized as one of the greatest Latin American essayists. With dazzling erudition, these essays breathe a modernity that, in a Latin American key, is very reminiscent of Walter Benjamin and the young Lukács, and they establish a critical discussion with the aesthetic avant-garde, the modern literary debate and the nascent cultural industry. Proof of this are the authors and themes that he deals with: Joyce, just after it was published in Spanish, the avant-garde “isms”, Chaplin, Isadora Duncan, Proust or Freud. An early reference to Borges already appears in an article from 1925.
