The first comprehensive history of John Venn’s life and work.

John Venn (1834–1923) is remembered today as the inventor of the famous Venn diagram. The postmortem fame of the diagram has until now eclipsed Venn’s own status as one of the most accomplished logicians of his day. Praised by John Stuart Mill as a “highly successful thinker” with much “power of original thought,” Venn had a profound influence on nineteenth-century scientists and philosophers, ranging from Mill and Francis Galton to Lewis Carroll and Charles Sanders Peirce. Venn was heir to a clerical Evangelical dynasty, but religious doubts led him to resign Holy Orders and instead focus on an academic career. He wrote influential textbooks on probability theory and logic, became a fellow of the Royal Society, and advocated alongside Henry Sidgwick for educational reform, including that of women’s higher education. Moreover, through his students, a direct line can be traced from Venn to the early analytic philosophy of G. E. Moore and Bertrand Russell, and family ties connect him to the famous Bloomsbury group. 

This essential book takes readers on Venn’s journey from Evangelical son to Cambridge don to explore his life and work in context. Drawing on Venn’s key writings and correspondence, published and unpublished, Lukas M. Verburgt unearths the legacy of the logician’s wide-ranging thinking while offering perspective on broader themes in religion, science, and the university in Victorian Britain. The rich picture that emerges of Venn, the person, is of a man with many sympathies—sometimes mutually reinforcing and at other times outwardly and inwardly contradictory.

William Whewell, the famous master of Trinity College in Cambridge, was a central figure in nineteenth-century British scientific culture and one of the last great polymaths. His influential work ranged from history and philosophy of science, education, architecture, mineralogy, and political economy to mathematics, engineering, natural theology, metaphysics, and moral philosophy. Among his many gifts to science was his role as cofounder and president of the British Association for the Advancement of Science and his wordsmithing; he coined the terms scientist, physicist, linguistics, and electrode. While he was himself an opponent of evolution through natural selection, Whewell’s most famous works, including his Bridgewater Treatise (1833) and Philosophy of the Inductive Sciences (1840), played a formative role in Charles Darwin’s creation of the theory of evolution. William Whewell: Victorian Polymath reexamines the whole of Whewell’s oeuvre, as well as the wide range and internal unity of his many polymathic endeavors, placing him within the early Victorian intellectual landscape and highlighting his exchanges with other important figures of the period, such as John Herschel, Charles Lyell, and Robert Peel. Bringing together a group of eminent and emergent scholars, the volume explores all major aspects of Whewell’s reform project and its legacy, both in the sciences and the humanities, in the Victorian era and beyond.
