To understand the fluid and controversial nature of art, Elena Oliveras considers the return of utopia after postmodernity, the expanding genres of the 21st century -such as self-fiction and quirky- and the Internet as an art producer. The relationship of aesthetics and art with politics and the role of the curator are some of the issues explored. In this new book, Oliveras presents the thinking of authors who -as Giorgio Agamben, Jacques Rancière, Jean-Luc Nancy, Boris Groys, Michel Onfray, Nicolas Bourriaud, Timotheus Vermeulen and Robin van den Akker- arouse great interest in their ideas and also have a strong presence in the contemporary debate. They belong to different generations and, while some (such asVermeulen and Van den Akker) begin to be recognized in our new century, others (Rancière or Nancy) had wide impact in the last decades of the last century and continue to have it for their most recent contributions, which are those discussed at this time. The book "continues with the objetives of the book "Estética: la cuestión del arte" (2004) elaborated over the course of my aesthetics theoretical classes in the Departamento de Artes de la Facultad de Filosofía y Letas, UBA with the valuable participation of the teachers of that chair. Again, we try to bring the reader closer to aesthetic ideas, this time on those developed in recent decades.".
