This book collects a variety of short essays on Stephen Gaukroger’s thought, by leading scholars, both senior and junior. Stephen Gaukroger (1950-2023) was one of the preeminent specialists of early modern science and philosophy, particularly their interrelations including under the heading ‘natural philosophy’, on the international scene, since the 1980s, starting with his prominent Cartesian scholarship (and biography) and moving towards the formidable 4-volume series on science and the shaping of modernity (from Emergence of a Scientific Culture to Civilization and the Culture of Science), dealing not just with early modernity but with the Enlightenment, German Romanticism and 20th-century society. This volume covers the thought of this highly-recognized scholar and engages with his works covering early modern philosophy, enlightenment, and contemporary periods, making it a must-read for any philosopher and historian of science.
