Russell Brand's calling for revolution now, to overthrow the system that he says supports extreme inequality. David Babbs, executive director of 38 Degrees, wants popular campaigns to bring about change and strengthen democracy. Juliet Barker re-examines the Great Revolt of 1381 and finds not a peasants' revolt but one by a new middle class in the shires, dissatisfied with a London elite. Philosopher Susan Neiman looks at how we are expected to abandon the adventures of youth if we are to grow up and asks, is there a new way to imagine what it means to be mature?
