La mutation du visible, volume 2 by Philippe Hamou explores the historical transformation of visual perception through the development of optical instruments in England. Focusing on the period from Francis Bacon to Robert Hooke, the book examines how microscopes and telescopes reshaped scientific understanding and philosophical conceptions of sight. Drawing on detailed historical analysis, Hamou investigates the interplay between technological innovation and epistemological change during the early modern era. This volume continues the author's scholarly inquiry into the cultural and scientific implications of seeing, offering insights into the evolution of observational practices that laid the foundation for modern science. Written in French, the work is part of a broader intellectual project examining the intersection of instrumentation, vision, and knowledge production in seventeenth-century Europe.
