In recent decades Roger Bartra has become an essential figure for understanding what it means to be Mexican today, based on key concepts such as melancholy and a national culture’s capacity for metamorphosis. Bartra has a doctorate in Sociology from the Sorbonne, is an Emeritus Professor at UNAM and has been a guest lecturer at different universities in Mexico, the United States and Spain. On this occasion, the event will focus on two books that are essential in order to understand his worldview, the essays Chamanes y robots: Reflexiones sobre el efecto placebo y la conciencia artificial, and Melancolía y cultura. In conversation with Jacobo García.
