This work investigates the intellectual transition from natural philosophy to modern theoretical science through the life and unpublished writings of Henry Cavendish. Russell K. McCormmach, a historian of science, utilizes primary source documents and biographical analysis to argue that Cavendish represents the archetype of the modern, full-time scientist. By examining the specific methodologies and scientific attitudes of the late 18th and early 19th centuries, the author constructs a framework for understanding how empirical inquiry evolved into the rigorous theoretical structures of the modern era.
