NEWTON (Isaac). Philosophiae Naturalis principia mathematica - Cantabrigiae [Cambridge], [Cornelius Crownfield at the University Press], 1713. In-4° bound in full blond calf, spine ribbed and gilt (contemporary binding). [4] ff, 484 pp, [4] ff. decorated with an engraved title finial and a folding plate. An enlarged second edition published 26 years after the original of 1687 in a limited edition of 750 copies from Cambridge University Press. It includes one of Newton's most famous texts, the Scholium Generale, published for the first time, in which Newton uses the expression Hypotheses non fingo in response to the many criticisms he received. In particular, in this chapter he opposed the natural philosophy of Descartes and Leibniz. A fundamental and revolutionary work in the history of physics and science, Principia mathematica is a synthesis that defends the physical unity of the universe. For the first time, a single mathematical and physical law became the explanation for the universe as a whole and its many elements, making a definitive break with medieval and ancient knowledge, in particular the concept of a binary world (natural/supernatural). Good condition despite a tired binding and a few brown spots, particularly on the fold-out plateEx-libris of Ferdinand Faber and handwritten dated inscriptions of M. Whitmann, 1844 and Ed. Hagendbroter ('), 1860.
