: Newton's critics argued that his treatment of gravity in the Principia saddles him with a substantial dilemma. If he insists that gravity is a real force, he must invoke action at a distance because of his explicit failure to characterize the mechanism underlying gravity. To avoid distant action, however, he must admit that gravity is not a real force, and that he has therefore failed to discover the actual cause of the phenomena associated with it. A reinterpretation of Newton's (...) distinction between the "mathematical" and the "physical" treatment of force indicates how he can reject each horn of this dilemma. (shrink)

In the eighteenth century, Newton's ideas were an important element of the dominant world view, but it was not immediately clear that they could play such a role. What made them seem philosophically relevant is investigated in the case of the Dutch Republic. At the universities people initially were rather sceptical about Newton's theories. Support came mainly from scientific amateurs who tried to place their religious feelings on a scientific footing. The Spinozists' claim that religion was refuted by mathematics created (...) the need for a scientific answer, which would demonstrate the fallaciousness of Spinoza's geometrical method and uphold revealed religion. In this article, it is shown in some detail how Newtonian ideas were put to such use among mathematical amateurs in Amsterdam, mainly under the influence of informal contacts with David Gregory and his circle. Physico-theology appeared not so much as a fresh start as a transformation of the older mathematical approach of philosophical and religious questions. (shrink)

Forty-two essays by authors from five continents and many disciplines provide a synthetic account of the history of the social sciences-including behavioral and economic sciences since the late eighteenth century. The authors emphasize the cultural and intellectual preconditions of social science, and its contested but important role in the history of the modern world. While there are many historical books on particular disciplines, there are very few about the social sciences generally, and none that deal with so much of the (...) world over so long a timespan.

Reasoning without experience is very slippery. A man may puzzle me by arguents [sic] … but I’le beleive my ey experience ↓my eyes.↓ernan mcmullin once remarked that, although the “avowedly tentative form” of the Queries “marks them off from the rest of Newton’s published work,” they are “the most significant source, perhaps, for the most general categories of matter and action that informed his research.”2 The Queries (or Quaestiones), which Newton inserted at the very end of the third book of (...) the Opticks3 or its Latin rendition, Optice,4 constitute that part of his optical magnum opus which he reworked and augmented the most—especially between 1704 and 1717. While the main text of the Opticks itself underwent .. (shrink)

During high summer 1721, while rioters and bankrupts gathered outside Parliament, Robert Walpole's new ministry forced through a bill to clear up the wreckage left by the stock-market crash, the South Sea Bubble, and the visionary projects swept away when it burst. In early August the President of the Royal Society Isaac Newton, a major investor in South Sea stock, and the Society's projectors, learned of a new commercial scheme promising apparently automatic profits, a project for a perpetual motion. Their (...) informants were a young Viennese courtier Joseph Emmanuel Fischer von Erlach, a contact of Desaguliers recently engaged in industrial espionage in northern England, and the Leiden physics professor Willem 'sGravesande, who had visited London five years earlier. They reported that they had been summoned to a remarkable series of demonstrations in the castle of Weissenstein, the seat of the Landgrave of Hesse-Kassel. In a carefully guarded room of the castle there was set up a hollow wooden wheel covered in oilcloth, about 12 feet in diameter and 18 inches thick on an axle 6 feet in length. Its designer, a Saxon engineer and clockmaker Johann Bessler, who travelled Germany under the name Orffyreus, had been in Kassel for four years, published schemes for perpetual motion and been appointed commercial councillor. The Landgrave, well-known as a patron of advanced engineering schemes, commissioned him to build a new machine and put it on show before expert witnesses (Figure 1). (shrink)

In this discussion paper, I seek to challenge Hylarie Kochiras’ recent claims on Newton’s attitude towards action at a distance, which will be presented in Section 1. In doing so, I shall include the positions of Andrew Janiak and John Henry in my discussion and present my own tackle on the matter . Additionally, I seek to strengthen Kochiras’ argument that Newton sought to explain the cause of gravity in terms of secondary causation . I also provide some specification on (...) what Kochiras calls ‘Newton’s substance counting problem’ . In conclusion, I suggest a historical correction .Keywords: Isaac Newton ; Action at a distance; Cause of gravity; Fourth letter to Bentley. (shrink)

In January and February 1720 John Theophilus Desaguliers, a fellow of the Royal Society and a popular lecturer and experimenter, engaged in a public argument with two booksellers, William Mears and John Woodward. Each side offered for sale a translation of Willem Jacob ’sGravesande’s Physices elementa mathematica, experimentis confirmata, an introduction to Isaac Newton’s natural philosophy. The adversaries challenged each other in letters placed within advertisements for their respective translations that appeared in the Post Boy. While historians of science have (...) long noted the existence of the two translations, the events following their publication have not been explored fully. Setting Desaguliers as the focal point allows the complexities buried beneath the surface of this affair to be revealed. Desaguliers’s behavior resulted from his past experiences with the book trade, the competition among public lecturers in London, his financial situation, and concerns about the preservation of his reputation. This episode demonstrates the necessity of finding a prominent role for newspaper advertisements in the study of public science and in histories of the book. (shrink)

In the early eighteenth century Newtonianism became popular in the Netherlands both in academic and non-academic circles. The ‘Book of Nature’ was interpreted with the help of Newton’s natural philosophy and his ideas about a providential deity, thereby greatly enhancing the attractiveness of physico-theology in the eighteenth-century United Provinces. Like other Europeans the Dutch welcomed physico-theology as a strategic means in their battle against irreligion and atheism. Bernard Nieuwentijt, Johan Lulofs, Petrus Camper, and Johannes Florentius Martinet were prominent experts in (...) the field. Combining Newtonian notions with Leibnizian optimism and romanticist trends, physico-theology remained popular in the Netherlands well into the nineteenth century.Author Keywords: Apologetics; Dutch Enlightenment; Physico-theology; Prophetic theology; Argument from design; Empiricism.
