Utopian town planning produced a distinctive type of settlement characterized by its square plan, collective ownership of properties, and communal dormitories. Some were sanctuaries from religious persecution, like those of the French Huguenots and American Shakers, while others were sanctuaries from the Industrial Revolution, like those imagined by Charles Fourier and Robert Owen. While they have traditionally been viewed separately, these settlements, Lewis shows, are really part of a continuous intellectual tradition that stretches from the early Protestant Reformation into modern times. Lewis is the Faison-Pierson-Stoddard Professor of Art History at Williams College. His books include Frank Furness: Architecture and the Violent Mind and The Gothic Revival.
