This paper is in three sections. The first establishes that Newton, in spite of a well-known passage in a letter to Richard Bentley of 1692, did believe in action at a distance. Many readers may see this merely as an act of supererogation, since it is so patently obvious that he did. However, there has been a long history among Newton scholars of allowing the letter to Bentley to over-ride all of Newton’s other pronouncements in favour of action at a (...) distance, with devastating effects on our understanding of related aspects of his physics and his theology. Furthermore, this misconceived scholarly endeavour shows no sign of abating. The second section then offers a historical reconstruction, based on Newton’s writings, of how, when and why he began to accept actions at a distance and make them one of the cornerstones of his physics. Finally, using this chronological account of Newton’s use of actions at a distance, the paper re-assesses the claims of B. J. T. Dobbs that Newton’s important manuscript, De gravitatione et aequipondio fluidorum, was written, not in the late 1660s or early 1670s as was previously supposed, but during the composition of the Principia, in 1684 or 1685.Keywords: Isaac Newton; Action-at-a-distance; Gravity; Force; Aether; Attraction.

This paper draws attention to the crucial importance of a new kind of precisely defined law of nature in the Scientific Revolution. All explanations in the mechanical philosophy depend upon the interactions of moving material particles; the laws of nature stipulate precisely how these interact; therefore, such explanations rely on the laws of nature. While this is obvious, the radically innovatory nature of these laws is not fully acknowledged in the historical literature. Indeed, a number of scholars have tried to (...) locate the origins of such laws in the medieval period. In the first part of this paper these claims are critically examined, and found at best to reveal important aspects of the background to the later idea, which could be drawn upon for legitimating purposes by the mechanical philosophers. The second part of the paper argues that the modern concept of laws of nature originates in René Descartes's work. It is shown that Descartes took his concept of laws of nature from the mathematical tradition, but recognized that he could not export it to the domain of physico-mathematics, to play a causal role, unless he could show that these laws were underwritten by God. It is argued that this is why, at an early stage of his philosophical development, Descartes had to turn to metaphysics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.1 (2001) 99-119 [Access article in PDF] Animism and Empiricism: Copernican Physics and the Origins of William Gilbert's Experimental Method John Henry In the second year of this journal's run, way back in 1941, appeared Edgar Zilsel's classic and still widely cited paper on The Origins of William Gilbert's Experimental Method. 1 Focusing on Gilbert's De magnete of 1600, undoubtedly a seminal text (...) in the history of the experimental method, 2 Zilsel argued that Gilbert borrowed his methodology from elite craftsmen, artisans, and other manual workers involved in mining, smelting, smithing, compass making, navigation, sailing, and other activities which involved working with iron or with magnets. 3 On its appearance the paper contributed to a growing and still continuing debate in the history of science about the relative importance of scholars and craftsmen in the origins of modern science. Although Zilsel's general thesis has been critically evaluated in terms of that wider debate, 4 his very specific claims about the [End Page 99] role of elite craftsmen in providing Gilbert with a ready-made experimental method, have never been properly considered. This paper attempts to reassess Zilsel's claims about the origin of Gilbert's experimental method and, in so doing, to arrive at a richer understanding of what Gilbert was trying to do in De magnete and to suggest an alternative source for his experimentalism.The first thing to note about Zilsel's argument is that it had two strands. 5 One of these pointed to actual experimental techniques used by Gilbert and showed that they can all be found in earlier writings on magnets. To be more specific, the techniques in question are to be found either in the thirteenth-century "Letter on the Magnet" written by Petrus Pergrinus or Pierre de Maricourt, first published in 1558, or in The Newe Attractive, a work on the magnetic compass written by a retired mariner, Robert Norman, first published in 1581 but reprinted three times before 1600. 6 The second strand did not involve experiments at all, with one notable exception, but simply implied or suggested that Gilbert's experimental techniques must have been inspired by miners and foundrymen, or navigators and instrument makers. The problem here, as others have objected, 7 is that it is by no means clear that elite craftsmen were engaged in performing experiments in anything like the sense of the word required for the argument to cut any ice. For Zilsel, however, "we cannot doubt that many of [the miners and foundrymen of the period], stimulated to improvements by economic competition, were wont to try new techniques and to observe natural processes." 8 A few sentences later we are told that it is "obvious" that "among such manual labourers there were experimentalists, though experimentalists with practical aims only and without theoretical knowledge." 9 [End Page 100]The philosopher of science at this point might legitimately want to suggest that an experiment is not an experiment unless it is testing a theory, but we do not have to enter into such arguable niceties. 10 We can see that there is something profoundly tendentious in Zilsel's claims simply by reading on. At this point Zilsel mentioned the only experiment specifically referred to in this strand of his argumentation. Quoting Gilbert, Zilsel showed that Gilbert himself must have descended into a mine in order, as Zilsel says, "to verify the hypothesis" that the polarity of a magnet derives from the polarity of the earth: We had a twenty pounds' heavy loadstone dug and hauled out after having first observed and marked its ends in its vein. Then we put the stone in a wooden tub on water, so that it could turn freely. Immediately the surface which had looked to the North in the mine turned itself to the North on the water. 11Zilsel did not make the absurd claim that Gilbert must have seen miners doing this kind of experiment, but he did all he could to...

ArgumentIt is argued that the sensorium of God was introduced into theQuaestionesadded to the end of Newton’sOptice(1706) as a way of answering objections that Newton had failed to provide a causal account of gravity in thePrincipia. The discussion of God’s sensorium indicated that gravity must be caused by God’s will. Newton did not leave it there, however, but went on to show how God’s will created active principles as secondary causes of gravity. There was nothing unusual in assuming that God, (...) acting as the First Cause, operated in nature by means of secondary causes; but it was unusual to devote as much time to discussing God’s precise role as to discussing the secondary causes themselves. It is contended that Newton felt the need to do this to persuade readers that what might seem like a second cause that could not possibly work could be made to work by the omnipotent God. (shrink)

Samuel Clarke is best known to historians of science for presenting Isaac Newton’s views to a wider audience, especially in his famous correspondence with G. W. Leibniz. Clarke’s independent writings, however, reveal positions that do not derive from, and do not coincide with, Newton’s. This essay compares Clarke’s and Newton’s ideas on the cause of gravity, with a view to clarifying our understanding of Newton’s views. There is evidence to suggest that Newton believed God was directly responsible for gravity, and (...) this interpretation has been promoted by a number of scholars. By comparing Newton’s views with those of Clarke, however, it can be seen that Newton did not subscribe to the kind of occasionalist approach to gravity that Clarke developed. Clarke insisted that matter was categorically incapable of being endowed with powers or forces and that therefore what looks like gravitational attraction has to be performed directly by God or by angels. By comparing Clarke’s pronouncements with Newton’s, it becomes clear that Newton adopted the more standard line: that the first cause, God, operated in nature through secondary causes and that gravitational attraction was just such a secondary (albeit occult) cause.

In spite of vigorous opposition by a number of historians it has now become a commonplace that the rapid development of the ‘new philosophy’ sprang from the ideology of Puritanism. What began its career as the ‘Merton thesis’ has now been refined, developed, and so often repeated that it seems to be almost unassailable. However, the two foremost historians in the entrenchment of this new orthodoxy are willing, in principle, to concede that ‘in reality things were very mixed up’, and (...) that non-Puritan natural philosophers at the time were operating ‘in a precisely similar manner’ to their Puritan contemporaries. Indeed, it would be impossible not to concede this in the face of the many critiques launched against the Merton thesis. (shrink)

ABSTRACT Looking in particular at the Scientific Revolution, this essay argues that, for all their differences, positivist commentators on science and contextualist historians of science ought to be committed to the view that counterfactual changes in the history of science would have made no significant difference to its historical development. Assumptions about the history of science as an inexorable march toward the truth commit the positivist to the view that, even if things had been different, scientific knowledge would still have (...) ended up where it is. Perhaps surprisingly, the move away from “great man” history and the increasing emphasis among contextualist historians on the broad cultural influences on scientific thought and practice also imply that changes of a restricted or specific nature ought to have no significant effect on general outcomes. Unlike the positivist, however, the contextualist is willing to concede that things might have been different if the entire cultural background had been different. But in such cases the effect of such sweeping changes would be impossible to conceive and so deprive counterfactual history of any useful insights it might be supposed to offer. (shrink)

This study considers the contribution of Francesco Patrizi da Cherso to the development of the concepts of void space and an infinite universe. Patrizi plays a greater role in the development of these concepts than any other single figure in the sixteenth century, and yet his work has been almost totally overlooked. I have outlined his views on space in terms of two major aspects of his philosophical attitude: on the one hand, he was a devoted Platonist and sought always (...) to establish Platonism, albeit his own version of it, as the only currect philosophy; and on the other hand, he was more determinedly anti-Aristotelian than any other philosopher at that time. Patrizi's concept of space has its beginnings in Platonic notions, but is extended and refined in the light of a vigorous critique of Aristotle's position. Finally, I consider the influence of Patrizi's ideas in the seventeenth century, when various thinkers are seeking to overthrow the Aristotelian concept of place and the equivalence of dimensionality with corporeality. Pierre Gassendi , for example, needed a coherent concept of void space in which his atoms could move, while Henry More sought to demonstrate the reality of incorporeal entities by reference to an incorporeal space. Both men could find the arguments they needed in Patrizi's comprehensive treatment of the subject. (shrink)

_ Source: _Volume 29, Issue 1, pp 9 - 38 Hobbes tried to develop a strict version of the mechanical philosophy, in which all physical phenomena were explained only in terms of bodies in motion, and the only forces allowed were forces of collision or impact. This ambition puts Hobbes into a select group of original thinkers, alongside Galileo, Isaac Beeckman, and Descartes. No other early modern thinkers developed a strict version of the mechanical philosophy. Natural philosophies relying solely on (...) bodies in motion require a concept of inertial motion. Beeckman and Descartes assumed rectilinear motions were rectilinear, but Galileo adopted a theory which has been referred to as circular inertia. Hobbes’s natural philosophy depended to a large extent on what he called “simple circular motions.” In this paper, I argue that Hobbes’s simple circular motions derived from Galileo’s belief in circular inertia. The paper opens with a section outlining Galileo’s concept, the following section shows how Hobbes’s physics depended upon circular motions, which are held to continue indefinitely. A third section shows the difficulty Hobbes had in maintaining a strictly mechanistic philosophy, and the conclusion offers some speculations as to why Galileo’s circular inertia was never entertained as a serious rival to rectilinear inertia, except by Hobbes.

La acción a distancia se ha considerado muy a menudo como un medio de explicación inaceptable en la física. Debido a que daba la impresión de resistirse a los intentos de asignarle causas propias a los efectos, la acción a distancia se ha proscrito como sinsentido ocultista. El rechazo de la acción a distancia fue el principal precepto del aristotelismo que fue tan dominante en la filosofía natural europea, y hasta hoy permanece como un prejuicio principal de la física moderna. (...) No obstante, hubo un período de interregno; un período durante el cual las acciones a distancia eran fácilmente aceptadas por un número ignificativo de filósofos naturales. La principal influencia sobre este nuevo enfoque radical hacia la naturaleza de la causalidad física fue, por supuesto, Isaac Newton. El principio de gravitación universal de Newton a muchos les pareció dar no sólo un ejemplo innegable de una fuerza cuya naturaleza no se podía producir por ningún tipo de contacto mecánico entre los cuerpos, sino también un modelo para otras supuestas fuerzas que podían suponerse que dan cuenta de los fenómenos químicos, biológicos y otros fenómenos físicos. Por tanto, durante el siglo XVIII, como lo han demostrado un gran número de importantes estudios históricos, los filósofos naturales buscaron hacer fructífero el deseo de Newton, expresado en el Prefacio a los Principia, de que todos los fenómenos de la naturaleza fueran explicados en términos de fuerzas atractivas y repulsivas que operan a distancia entre las partículas diminutas de los cuerpos. Sin embargo, en la actualidad el rechazo a la legitimidad de las acciones a distancia es tan grande que una serie de notables especialistas de Newton han insistido en que Newton nunca creyó en la actio in distans y que fue completamente malentendido por la generación que le sucedió. Este artículo reitera que Newton sí creía en la acción a distancia y refuta los argumentos de especialistas recientes que sostienen lo contrario. (shrink)

This chapter, which examines the work of Rene Descartes and the reception of Cartesianism in Great Britain in the seventeenth century, suggests that Descartes was an undeniably influential figure during this period, and explains that he exposed the faults of the philosophy before him and pointed the way forward. It also highlights the fact that Cartesianism was accepted in the universities after Aristotelianism was significantly affected by innovations in the sciences and university curricula in natural philosophy had to be changed.

John Henry gives a dramatic account of the background to Bacon's innovations and the sometimes unconventional sources for his ideas.

Certified nursing assistants (CNAs) provide up to 80% of the direct care to older adults in long‐term care facilities. CNAs are perceived as being at the bottom of the hierarchy among healthcare professionals often negatively affecting their job satisfaction. However, many CNAs persevere in providing quality care and even reporting high levels of job satisfaction. The aim of the present investigation was to identify primary themes that may help CNAs make meaning of their chosen career; thus potentially partially explaining increases (...) in job satisfaction among this group. Focus groups were conducted with CNAs at three long‐term care facilities. Four themes emerged from the data: CNA work is good or special; CNA as relationship builder; CNA as expert; CNA as team member. These themes reflect the perceptions that these CNAs held in regard to themselves and their relationships to others in the work environment and, when present, can contribute to intrinsic job satisfaction. Our meaning‐making themes support the premise that CNAs do not passively accept the evaluations of others but instead actively frame identities that validate their importance to residents and the institution.

This paper offers a caution that emphasis upon the importance of mathematics in recent historiography is in danger of obscuring the historical fact that, for the most part, mathematics was not seen as important in the pre-modern period. The paper proceeds by following a single case study, and in so doing offers the first account of the mathematical writings of Jean Fernel (1497–1558), better known as a leading medical innovator of the 16th century. After establishing Fernel's early commitment to mathematics, (...) and attempt to forge a career as a cosmographer, it goes on to explain his abandonment of mathematics for a career in medicine. The ‘mathematization of the world picture’ is usually explained in terms of the perceived usefulness of mathematics, but Fernel's case shows that for many pre-modern thinkers mathematics was not regarded as a useful pursuit. The paper should serve as a reminder, therefore, that the take-up of mathematics by natural philosophers was by no means inevitable, but had to be carefully managed by early modern mathematical practitioners. The case of Fernel indicates that perhaps he was not the only would-be mathematical practitioner to abandon mathematics in favour of a calling that was more appreciated by contemporaries. (shrink)

Noting that the doctrine of the general resurrection attracted renewed attention after the Reformation, and after the atomist revival led to the displacement of traditional hylomorphism by alternative matter theories, this article surveys the ways in which the resurrection was discussed by leading natural philosophers in seventeenth‐century England. These include discussion of how bodily resurrection might be possible, what resurrected bodies will be like; as well as the nature of living conditions after the resurrection. It is indicated that the resurrection (...) seems to have played a much less prominent place in the writings of natural philosophers than the doctrine of the immortality of the soul, and other issues of natural theology. Reasons for this lack of prominence are tentatively offered, chiefly focusing on its unsuitability for combatting the perceived atheism of the time. It is hoped that this preliminary survey might inspire others to extend the survey, especially to cover Continental philosophers. (shrink)

Established religions integrate a society's everyday secular realities with humankind's numinous experience of the holy. Powerful emotions nourish the cultural expression of the archetypes propelling the “ritual dances” of art, sport, and technocracy. During sacred moments such as mother‐infant or adult bonding, neuroendocrine triggers activate lifelong ties. The cultural canon of the left cortex contrasts with the intuitive right. Brainstem “switches” alternate the left's cool, extraverted, sympathetic drive for control with the right's “warm” attachment behavior and dreaming sleep. Psychic trauma (...) damages flexibility with resultant alexithymic blindness to emotions and archetypes. Substance abuse and narcissistic overemphasis on control ensue. (shrink)

In theology there has never been any doubt that God can cause things to happen, but there has been a great deal of controversy about the precise nature of God’s causal activity in nature. The theory of divine concurrentism (both God, as primary cause, and creatures, as secondary causes, are engaged in causal processes), fostering the middle way between the anti-providential notion of natural causation and occasionalism (which attributes all causation to God), was questioned in the era of modern science (...) and philosophy. The restriction of divine action to the moment of the first creation in deism led to the agnostic and atheistic rejection of God as an ‘unnecessary hypothesis.’ Most theological responses to this crisis followed the restriction of causality to efficient causes, showing an implicit tendency to speak about the causation of God and creatures in univocal terms and trying to define the ‘causal joint’ between God and nature. A philosophical analysis of evolutionary biology, emergence, big bang cosmology, chaos theory, and quantum mechanics, however, has recently brought a retrieval of a broader understanding of causation, triggering a renewed interest in divine action. The topic of causality has raised interest among analytical philosophers as well. Those following the metaphysics of dispositions and manifestations acknowledge the neo-Aristotelian flavor of their analyses, which becomes, in turn, an incentive for a revival of the classical version of divine concurrentism.

ABSTRACT As well as the mathematically-supported celestial mechanics that Newton developed in his Principia, Newton also proposed a more speculative natural philosophy of interparticulate forces of attraction and repulsion. Although this speculative philosophy was not made public before the ‘Queries’ which Newton appended to the Opticks, it originated far earlier in Newton’s career. This article makes the case that Newton’s short, unfinished manuscript, entitled ‘De Aere et Aethere’, should be seen as an important landmark in Newton’s intellectual development, being the (...) first work in which Newton assumed there are repulsive forces operating at a distance between the particles of bodies. The article offers an account of how Newton came to write ‘De Aere et Aethere’ and why. It also outlines its relationship to the ‘Conclusio’, with which Newton briefly intended to finish the Principia, and to the ‘Queries’ in the Opticks. The date of the manuscript is disputed, and the article also aims to settle this dispute. Claims that the ‘De Aere et Aethere’ must have been written before the ‘Hypothesis... of Light’ of 1675 are dismissed, and it is suggested, following R. S. Westfall, that it was written after a well-known letter Newton wrote to Boyle early in 1679. (shrink)

This chapter focuses on the English response to Thomas Hobbes as a mechanical philosopher. Hobbes's mechanical philosophy was by no means merely derivative from Descartes's Principia philosophiae; indeed, Hobbes came closer than anyone else to developing a mechanistic system to match it. Hobbes's system was a carefully thought‐out and uniquely original system of mechanical philosophy, and none of his contemporaries, not even his staunchest critics, ever considered it to be simply derived from Cartesianism. An important aspect of the dispute between (...) Robert Boyle and Hobbes was concerned with the correct method to arrive at knowledge of the natural world. The distinctions between the thought of Hobbes and his critical contemporaries were by no means as stark as his critics wanted to maintain, but were highly nuanced. This can be seen in the marked similarity between Hobbes's concept of a corporeal God, and Henry More's influential concept of a supposedly immaterial but nonetheless three‐dimensionally extended God.
