The government led by Syriza in Greece, elected in January of 2015, seemed, at least in its initial months, to be the most radical European government in recent history. It proclaimed itself as the 'government of hope' and became a symbol of hope throughout the world. It represented for many the proof that radical change could be achieved through institutional politics. Then came the referendum of July 2015, the vote to reject the austerity imposed by the banks and the European Union, followed by the complete reversal of the government's position and its acceptance of that austerity. The dramatic collapse of the Syriza government's radical discourse showed the limits of institutional politics, a lesson that is apparently completely overlooked by the enthusiastic followers of Jeremy Corbyn and Bernie Sanders. But it also poses profound questions for those who reject state-centred politics. The anarchist or autonomist movement in Greece has been one of the strongest in the world yet it has failed to have a significant impact in opening up alternative perspectives in this situation. Is there then no way out? Is there nothing beyond the world of capitalist destruction or can we still see some possibility for radical hope? The essays in this collection reflect on the experience of the crisis in Greece and its political implications for the whole world. They do not point a way forward but seek to open windows in the darkening sky of apparent impossibility.
