“Bento Prado Jr. brings to bear the magnitude of his thought and the range of his cultural understanding, which were already discernible in his previous work, on the philosophy that he develops in this book and that is as original as it is profound, situating the author at the interface between the continental and the analytical traditions. With Error, Illusion, Madness, Prado Jr. emerges as the greatest Brazilian philosopher of the twentieth century.”Renaud Barbaras, University of Paris 1 Panthéon-Sorbonne
