I have a mild obsession with human attempts to create heaven on earth. Of course, their idealism is infectious: who doesn’t want heaven on earth? But such visions always come with a cost – in whatever society, in whatever generation. But if modernist visions of utopia have been about projecting the dream of the future through rejection of the past, others have been more concerned with recreating the long-gone, supposedly golden past. The English Arcadian vision is one such: it gripped several generations before the English Civil War and is the subject of Adam Nicolson’s fascinating book Arcadia: The Dream of Perfection in Renaissance England.
