'By stressing the deep traditionalism of Maxwell's enterprise, Harman makes him a participant in a philosophical conversation about matter, motion and mind, well-established by the time of Newton and continuing into this century.' Simon Schaffer, London Review of Books 'The sections on Maxwell's physics in this book are presented with admirable clarity, particularly the intricacies of how his theory of electromagnetism developed, which are usually difficult to follow. This presentation gives the general reader a clear overview of Maxwell's work, while the discussion of how Maxwell's physics developed with time provides a good insight into how philosophical ideas matured.' Elizabeth Garber, Physics World '… not the least of his talents is his ability to present brief, informed, and intelligible, accounts of the results of such analysis and use them in his argumentation.' Ole Knudsen, Centaurus 'The book is wonderfully informative and insightful throughout; its merit lies as much in stimulating questions as in providing answers.' Daniel Siegal, American Scientist ''Natural Philosopher' probably captures as much of Maxwell as any single label can, and Harman is to be commended for bringing a measure of synthesis to our picture of one of the most important but elusive figures of Victorian science.' Bruce J. Hunt, Book Reviews - Isis, 91 'James Clerk Maxwell (1831–1879) belonged to the 'golden age' of classical physics and contributed to many of its great achievements … In addition to the philosophical focus of the text, the book is full of interesting historical detail, and is very fully annotated; it would be enjoyed by anyone with a scholarly interest in the history of physics in the 'golden age'.
