''His finest work and one that was both symptom and engine of the concept of "history from below" ... Here Levellers, Diggers, Ranters, Muggletonians, the early Quakers and others taking advantage of the collapse of censorship to bid for new kinds of freedom were given centre stage ... Hill lives on'' Times Higher Education

In ''The World Turned Upside Down'' Christopher Hill studies the beliefs of such radical groups as the Diggers, the Ranters, the Levellers and others, and the social and emotional impulses that gave rise to them. The relations between rich and poor classes, the part played by wandering ''masterless'' men, the outbursts of sexual freedom, the great imaginative creations of Milton and Bunyan - these and many other elements build up into a marvellously detailed and coherent portrait of this strange, sudden effusion of revolutionary beliefs.
