Alexandre Koyré

Alexandre Koyré (1892–1964) was a French philosopher of Russian origin who made significant contributions to the history and philosophy of science. Born Alexandr Vladimirovich Koyra in Taganrog, Russian Empire, he studied in Europe under influential figures like Henri Bergson and Edmund Husserl. After serving in World War I, Koyré taught at the École pratique des hautes études in Paris and later at institutions in Egypt, the United States, and other countries. His most famous work, "From the Closed World to the Infinite Universe," explores the conceptual shift in understanding the cosmos from Nicholas of Cusa to Newton. Koyré critiqued positivist views of science, arguing that scientific revolutions were driven more by changes in theoretical perspective and historical context than by empirical data alone. He highlighted the interplay between scientific discoveries and religious or philosophical worldviews, noting the emergence of a split between the human phenomenal world and the abstract mathematical world of science. His work influenced prominent philosophers of science such as Thomas Kuhn and Michel Foucault. Koyré died in Paris in 1964.
