Pierre Duhem
modernPhilosophy of Science, Instrumentalism, Conventionalism1861 – 1916
Pierre Duhem (1861–1916) was a French physicist, historian, and philosopher of science who made foundational contributions to thermodynamics and the philosophy of physics. He championed an instrumentalist view of scientific theories, arguing they are classificatory tools rather than literal descriptions of reality. His historical research rehabilitated medieval natural philosophy as a genuine precursor to modern science.
