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 Drawing on Venn’s key writings and correspondence, published and unpublished, Lukas M. Verburgt unearths the legacy of the logician’s wide-ranging thinking while offering perspective on broader themes in religion, science, and the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.
I.B.Tauris in association with the Iran Heritage Foundation The decline and fall of Safavid Iran is traditionally seen as the natural outcome of the unrelieved political stagnation and moral degeneration which characterised late Safavid Iran. "Persia in Crisis" challenges this view. In this ground-breaking new book, Rudi Matthee revisits traditional sources and introduces new ones to take a fresh look at Safavid Iran in the century preceding the fall of Isfahan in 1722, which brought down the dynasty and ushered in a long period of turbulence in Iranian history. Inherently vulnerable because of the country's physical environment, its tribal makeup and a small economic base, the Safavid state was fatally weakened over the course of the seventeenth century. Matthee views Safavid Iran as a network of precarious alliances subject to perpetual negotiation and the society they ruled as an uneasy balance between conflicting forces. In the later seventeenth century this delicate balance shifted from cohesion to fragmentation. An increasingly detached, palace-bound shah; a weakening link between the capital and the outlying provinces; the regime's neglect of the military and its shortsighted monetary policies combined to exacerbate rather than redress existing problems, leaving the country with a ruler too feeble to hold factionalism and corruption in check and a military unable to defend its borders against outside attack by Ottomans and Afghans. The scene was set for the Crisis of 1722. This book makes a major contribution to our understanding of Iranian history and the period that led to two hundred years of decline and eclipse for Iran.
