Abstract

The chapter focusses on the Scottish natural philosophy of the late eighteenth century represented by John Anderson (1726–1796) and John Robison (1739–1805), which is considered a link between Newton’s natural philosophy and nineteenth-century physics in Britain (Kelvin and Maxwell). Anderson and Robison have to be seen in a tradition of Scottish Newtonians established in the seventeenth century by David Gregory and John Keill and specifically shaped in the Mid-eighteenth century through the chemical-physical work of Joseph Black and the common-sense philosophy of Thomas Reid. These latter Newtonians built on Newton’s theory of matter and short-range forces as indicated in Query 31 of his Opticks (Black) but also on his Rules of Reasoning of the second edition of his Principia (Black and Reid) and in this way created the theoretical framework in which Anderson and Robison developed their natural philosophy. In the center of their natural philosophy, which was oriented on experimental investigations, were the manifold open questions of the Baconian sciences of that time - theories of heat, light, electricity, magnetism as well as the understanding of the phlogiston. The chapter thus provides insight into the specific way in which the Newtonian camp participated in early modern natural philosophical speculations about minute particles of matter, fluids, or the propagation of light and heat.
