William Whewell was a giant of Victorian intellectual culture. His influence, whether recognized or forgotten, is palpable in areas as diverse as moral philosophy, mineralogy, architecture, the politics of education, physics, engineering, and theology. Recent studies of the place of the sciences in nineteenth-century Britain have repeatedly indicated the significance of Whewell's sweeping and critical proposals for a reformed account of scientific knowledge and moral values.However, until now there has been no detailed study of the context and impact of his project. This collection of essays by recognized authorities in the fields of history, history of science, and philosophy thus represents the first attempt to do justice to a magisterial nineteenth-century intellectual. More generally, it makes an important contribution to our understanding of Victorian intellectual life and its aftermath.
