Properties and causes: An approach to the problem of hypothesis in the scientific methodology of Sir Isaac Newton

This article considers the differential absorption and integration of refugee physicists into various countries during the 1930s, and the social and intellectual factors responsible for this, focusing particularly on the social functions of the British and American university at that period, as well as continuing ideological struggles in the Soviet Union. More generally, the issue of the relative absorption of refugee physicists is used to examine the nature of the physics communities and other institutions of the host societies.     

William Whiston, Isaac Newton and the crisis of publicity

William Whiston was one of the first British converts to Newtonian physics and his 1696 New theory of the earth is the first full-length popularization of the natural philosophy of the Principia. Impressed with his young protégé, Newton paved the way for Whiston to succeed him as Lucasian Professor of Mathematics in 1702. Already a leading Newtonian natural philosopher, Whiston also came to espouse Newton’s heretical antitrinitarianism in the middle of the first decade of the eighteenth century. In all, Whiston enjoyed twenty years of contact with Newton dating from 1694. Although they shared so much ideologically, the two men fell out when Whiston began to proclaim openly the heresy that Newton strove to conceal from the prying eyes of the public. This paper provides a full account of this crisis of publicity by outlining Whiston’s efforts to make both Newton’s natural philosophy and heterodox theology public through popular texts, broadsheets and coffee house lectures. Whiston’s attempts to draw Newton out through published hints and innuendos, combined with his very public religious crusade, rendered the erstwhile disciple a dangerous liability to the great man and helps explain Newton’s eventual break with him, along with his refusal to support Whiston’s nomination to the Royal Society. This study not only traces Whiston’s successes in preaching the gospel of Newton’s physics and theology, but demonstrates the ways in which Whiston, who resolutely refused to accept Newton’s epistemic distinction between ‘open’ and ‘closed’ forms of knowledge, transformed Newton’s grand programme into a singularly exoteric system and drove it into the public sphere.     

Isaac Newton and the problem of the earth's shape

In this article I discuss the theory of the earth's shape presented by Isaac Newton in Book III of his Principia. I show that the theory struck even the most reputable continental mathematicians of the day as incomprehensible. I examine the many obstacles to understanding the theory which the reader faced — the gaps, the underived equations, the unproven assertions, the dependence upon corollaries to practically incomprehensible theorems in Book I of the Principia and the ambiguities of these corollaries, the conjectures without explanations of their bases, the inconsistencies, and so forth. I explain why these apparent drawbacks are, historically considered, strengths of Newton's theory of the earth's shape, not weaknesses.     

Written in the flesh: Isaac Newton on the mind–body relation

Isaac Newton’s views on the mind–body relation are of interest not only because of their somewhat unique departure from popular early modern conceptions of mind and its relation to body, but also because of their connections with other aspects of Newton’s thought. In this paper I argue that (1) Newton accepted an interesting sort of mind–body monism, one which defies neat categorization, but which clearly departs from Cartesian substance dualism, and (2) Newton took the power by which we move our bodies by thought alone to be a member of the family of forces that includes gravity and electricity. Time and again, Newton draws an analogy between the ultimate cause and nature of the volitional powers of mind and the ultimate cause and nature of these other forces.     

Henry More and the development of absolute time

This paper explores the nature, development and influence of the first English account of absolute time, put forward in the mid-seventeenth century by the ‘Cambridge Platonist’ Henry More. Against claims in the literature that More does not have an account of time, this paper sets out More's evolving account and shows that it reveals the lasting influence of Plotinus. Further, this paper argues that More developed his views on time in response to his adoption of Descartes' vortex cosmology and cosmogony, providing new evidence of More's wider project to absorb Cartesian natural philosophy into his Platonic metaphysics. Finally, this paper argues that More should be added to the list of sources that later English thinkers – including Newton and Samuel Clarke – drew on in constructing their absolute accounts of time.     

‘The long-lost truth’: Sir Isaac Newton and the Newtonian pursuit of ancient knowledge

In the 1720s the antiquary and Newtonian scholar Dr. William Stukeley (1687-1765) described his friend Isaac Newton as ‘the Great Restorer of True Philosophy’. Newton himself in his posthumously published Observations upon the prophecies of Daniel, and the Apocalypse of St. John (1733) predicted that the imminent fulfilment of Scripture prophecy would see ‘a recovery and re-establishment of the long-lost truth’. In this paper I examine the background to Newton’s interest in ancient philosophy and theology, and how it related to modern natural philosophical discovery. I look at the way in which the idea of a ‘long-lost truth’ interested others within Newton’s immediate circle, and in particular how it was carried forward by Stukeley’s researches into ancient British antiquities. I show how an interest in and respect for ancient philosophical knowledge remained strong within the first half of the eighteenth century.     

Models, scientific realism, the intelligibility of nature, and their cultural significance

In this article, I will view realist and non-realist accounts of scientific models within the larger context of the cultural significance of scientific knowledge. I begin by looking at the historical context and origins of the problem of scientific realism, and claim that it is originally of cultural and not only philosophical, significance. The cultural significance of debates on the epistemological status of scientific models is then related to the question of ‘intelligibility’ and how science, through models, can give us knowledge of the world by presenting us with an ‘intelligible account/picture of the world’, thus fulfilling its cultural-epistemic role. Realists typically assert that science can perform this role, while non-realists deny this. The various strategies adopted by realists and non-realists in making good their respective claims, is then traced to their cultural motivations. Finally I discuss the cultural implications of adopting realist or non-realist views of models through a discussion of the views of Rorty, Gellner, Van Fraassen and Clifford Hooker on the cultural significance of scientific knowledge.     

Boussingault versus ville: The social,political and scientific aspects of their disputes

A feature of mid-nineteenth century scientific debates in France on the subject of plant nutrition was the rivalry, at times acrimonious, between Jean Baptiste Boussingault and Georges Ville. It started in 1848 when Ville was demonstrator to Boussingault, who held one of the two chairs of agriculture at the Conservatoire des Arts et Métiers. A study of their disputes serves to illustrate their mutual incompatibility, exacerbated by the patronage extended to Ville by his step-brother, Louis Napoléon Bonaparte, afterwards Napoléon III. Their disputes were not merely the result of personal differences but also accompanied the development of two concepts of plant nutrition, namely the rôle of atmospheric nitrogen. and its possible assimilation by plants, and the chemical nature of plant nutrients, especially nitrates and phosphates.     

On Joseph Fourier: the man,the mathematician and the physicist

In 1793 Lord Macartney arrived in China as ambassador of King George III. The aims of his embassy were largely directed towards the enlargement of British trade with the far east, and especially with China. The embassy also had a diplomatic and cultural mission, to impress the Chinese with British achievements. They were to do so largely by distributing presents of British manufactures, chief among them being scientific instruments. The Chinese refused the embassy's requests, and clearly regarded the gifts of instruments as merely ingenious toys. This paper describes the role of instruments in the embassy, and contrasts British expectations with Chinese attitudes to scientific instruments. The embassy's failure is shown to reveal fundamental differences in British and Chinese eighteenth-century responses to science, and has wide cultural implications.     

Newton,Gases, and Daltonian chemistry: The foundations of combination in definite proportion

This study deals with the relationship between Newton's gas model in the Principia (Book II, Proposition xxiii) and Dalton's theorizing. Dalton's first theory of mixed gases is an elegant extension of the Newtonian gas model which, in turn, led Dalton to a general model of chemical combination. The views on combination are contrasted with those of Arnold Thackray. Interestingly, the model of combination was knowingly based on a falsified theory.     

On reading Newton as an Epicurean: Kant,Spinozism and the changes to the Principia

This paper argues for three distinct, albeit mutually illuminating theses: first it explains why well informed eighteenth-century thinkers, e.g., the pre-critical Immanuel Kant and Richard Bentley would have identified important aspects of Newton’s natural philosophy with (a species of modern) Epicureanism. Second, it explores how some significant changes to Newton’s Principia between the first (1687) and second (1713) editions can be explained in terms of attempts to reframe the Principia so that the charge of “Epicureanism” can be deflected. In order to account for this, the paper discusses the political and theological changes in the wake of the Glorious Revolution (1688); Bentley plays a non-trivial role in these matters. Third, the paper argues that there is an argument in Kant’s (1755) Universal Natural History and Theory of the Heavens that undermines a key claim of Newton’s General Scholium that was used to discredit Spinozism by Clarke in A demonstration of the being and attributes of God.     

Chemist,entomologist, Darwinian,and man of affairs: Raphael Meldola and the making of a scientific career

In 1925 a debate erupted in the correspondence columns of the British Medical Journal concerning the effectiveness of eating raw pancreas as a treatment for diabetes. Enthusiasts were predominantly general practitioners (GPs), who claimed success for the therapy on the basis of their clinical impressions. Their detractors were laboratory‐oriented ‘biochemist‐physicians,’ who considered that their own experiments demonstrated that raw pancreas therapy was ineffective. The biochemist‐physicians consistently dismissed the GPs' observations as inadequately ‘controlled’. They did not define the meaning of ‘control’ in this context, although it clearly did not have the term's present‐day meaning of a trial employing an untreated comparison group of patients. Rather, the physician‐biochemists' ‘properly controlled’ experiments involved careful regulation of their patients' diet and other environmental factors, and evaluation of the therapy's success through biochemical, rather than just clinical, criteria. However, my analysis suggests that these factors alone are inadequate to account for the biochemist‐physicians' dismissal of the GPs' work as ‘uncontrolled’. I suggest that the biochemist‐physicians were deliberately exploiting the powerful rhetorical connotations of the term ‘control’. Ultimately, they implied that only a trial which they themselves had conducted could be deemed ‘adequately controlled’.     

The birth of modern science: culture, mentalities and scientific innovation

In a recent paper, Luc Faucher and others have argued for the existence of deep cultural differences between ‘Chinese’ and ‘East Asian’ ways of understanding the world and those of ‘ancient Greeks’ and ‘Americans’. Rejecting Alison Gopnik’s speculation that the development of modern science was driven by the increasing availability of leisure and information in the late Renaissance, they claim instead—following Richard Nisbett—that the birth of mathematical science was aided by ‘Greek’, or ‘Western’, cultural norms that encouraged analytic, abstract and rational theorizing. They argue that ‘Chinese’ and ‘East Asian’ cultural norms favoured, by contrast, holistic, concrete and dialectical modes of thinking. After clarifying some of the things that can be meant by ‘culture’ and ‘mentality’, the present paper shows that Faucher and his colleagues make a number of appeals—to the authority of comparative studies and history of science, to the psychological studies of Nisbett and his colleagues, and to a hidden assumption of strong cultural continuity in the West. It is argued that every one of these appeals is misguided, and, further, that the psychological findings of Nisbett and others have little bearing on questions concerning the origins of modern science. Finally, it is suggested that the ‘Needham question’ about why the birth of modern science occurred in Europe rather than anywhere else is itself multiply confused to the extent that it may express no significant query.
