Post-Modernity is the creative destruction that has shattered our present times into fragments. It dynamited modernism which had dominated the western world for most of the 20th century. Post-modernism stood for everything modernism rejected: fun, exuberance, irresponsibility. But beneath its glitzy surface, post-modernism had a dirty secret: it was the fig leaf for a rapacious new kind of capitalism. It was also the forcing ground of the 'post truth', by means of which western values got turned upside down. But where do these ideas come from and how have they impacted on the world? In his history of a dangerous idea, Stuart Jeffries tells a narrative that starts in the early 1970s and continue to today.
