Contributor(s): Paul Mason | Our world is changing dramatically. Social upheaval has followed worldwide economic crisis and the gulf between the haves and the have-nots is widening. In 2011, this profound disconnect found expression in events that we were told had been consigned to history: revolt and revolution. In his new book Why It's Kicking Off Everywhere which he will discuss in this lecture Paul Mason sets out to explore the causes and consequences of this current wave of struggle, illuminating the links between the economic and social crisis. He explores and analyses what lies behind the new revolutions – a volatile combination of the near collapse of free-market capitalism, new technologies and changes in popular culture, and a profound shift in our understanding of what freedom means. Looking at how new social media have impacted on how we behave and organize, Mason interviews activists on the ground and the people behind these new forms of collective action, providing an insight into the agile networks of Twitter- and Facebook-savvy young protesters supporting the viral spread ofinternational activism. The economics editor of the BBC's flagship program Newsnight, Paul Mason is also one of the most influential journalists on twitter. He first reported live for the BBC on 9/11, and covered the collapse of Lehman Brothers in 2008 from outside its New York HQ. His television and online reports have tracked the social and economic impact of the global meltdown from the mean streets of Gary, Indiana to the elite salons of Davos.
