This book is the first to trace the origins and significance of positivism on a global scale. Taking their cues from Auguste Comte and John Stuart Mill, positivists pioneered a universal, experience-based culture of scientific inquiry for studying nature and society-a new science that would enlighten all of humankind. Positivists envisaged one world united by science, but their efforts spawned many. Uncovering these worlds of positivism, the volume ranges from India, the Ottoman Empire, and the Iberian Peninsula to Central Europe, Russia, and Brazil, examining positivism's impact as one of the most far-reaching intellectual movements of the modern world. Positivists reinvented science, claiming it to be distinct from and superior to the humanities. They predicated political governance on their refashioned science of society, and as political activists, they sought and often failed to reconcile their universalism with the values of multiculturalism. Providing a genealogy of scientific governance that is sorely needed in an age of post-truth politics, this volume breaks new ground in the fields of intellectual and global history, the history of science, and philosophy.

Born in Germany, Georg Iggers escaped from Nazism to the United States in his adolescence where he became one of the most distinguished scholars of European intellectual history and the history of historiography. In his lectures, delivered all over the world, and in his numerous books, translated into many languages, Georg Iggers has reshaped historiography and indefatigably promoted cross-cultural dialogue. This volume reflects the profound impact of his oeuvre. Among the contributors are leading intellectual historians but also younger scholars who explore the various cultural contexts of modern historiography, focusing on changes of European and American scholarship, as well as non-Western historical writing in relation to developments in the West. Addressing these changes from a transnational perspective, this well-rounded volume offers an excellent introduction to the field, which will be of interest to both established historians and graduate students.
