This chapter describes various aspects of the impact on philosophy of Newton’s Principia. It shows how Newton’s achievement dramatically influenced debates over the way subsequent philosophers conceived of their activity, and thus prepared the way for an institutional and methodological split between philosophy and science. These large-scale themes are illustrated by attention to a number of detailed debates over the nature and importance of Newton’s legacy: debates concerning gravity and matter theory, the status of Newton’s “laws of motion”, the role of final causes in natural philosophy, and the interpretation of Newton’s “rules for the study of natural philosophy”. Important contributors to these debates included Hume, Colin Maclaurin, Priestley, and Reid. The chapter also includes discussion of how eighteenth-century philosophers understood Newton’s place in the history of science.

The main aim of this paper is to explore why it is so important for Hume to defi ne ‘cause’ as he does. This will shed light on the signifi cance of the natural/philosophical relation (hereafter NPR) distinction in the Treatise. Hume's use of the NPR distinction allows him to dismiss on general grounds conceptions of causation at odds with his own. In particular, it allows him to avoid having to engage in detailed re-interpretation of potentially confl icting theories formulated by natural philosophers. Moreover, it provides an instance of the normative nature of Hume's “science of man.” The paper argues that the NPR distinction - in conjunction with the so-called copy principle - is meant to undercut appeals to the authority of theories not founded on Hume's “principles.” In order to illustrate its claims about Hume, this essay explores some aspects of Newton's natural philosophy. Finally, this paper resolves a long-standing interpretive problem: how to reconcile Hume's two “defi nitions” of causation in the Treatise

In this paper I clarify what Newton could have meant when he insisted that gravity is a real force. I interpret Newton’s speculative treatment of gravity as a relational, accidental quality of matter that arises through what Newton calls “the shared action” of two bodies. I argue that when Newton drafted the first edition of the Principia in the mid 1680s, he thought that (at least a part of) the cause of gravity is the disposition inherent in any individual body, but that the force of gravity is the actualization of that disposition; a necessary condition for the actualization of the disposition is the actual obtaining of a relation between two bodies having the disposition. The cause of gravity is not essential to matter because God could have created matter without that disposition. Nevertheless, at least a part of the cause of gravity inheres in individual bodies and were there one body in the universe it would inhere in that body. On the other hand, the force of gravity is neither essential to matter nor inherent in matter, because (to repeat) it is the actualization of a shared disposition. A lone part-less particle would, thus, not generate a gravity field.

The first two sections of this paper investigate what Newton could have meant in a now famous passage from “De Graviatione” (hereafter “DeGrav”) that “space is as it were an emanative effect of God.” First it offers a careful examination of the four key passages within DeGrav that bear on this. The paper shows that the internal logic of Newton’s argument permits several interpretations. In doing so, the paper calls attention to a Spinozistic strain in Newton’s thought. Second it sketches four interpretive options: (i) one approach is generic neo-Platonic; (ii) another approach is associated with the Cambridge Platonist, Henry More; a variant on this (ii*) emphasizes that Newton mixes Platonist and Epicurean themes; (iii) a necessitarian approach; (iv) an approach connected with Bacon’s efforts to reformulate a useful notion of form and laws of nature. Hitherto only the second and third options have received scholarly attention in scholarship on DeGrav. The paper offers new arguments to treat Newtonian emanation as a species of Baconian formal causation as articulated, especially, in the first few aphorisms of part two of Bacon’s New Organon. If we treat Newtonian emanation as a species of formal causation then the necessitarian reading can be combined with most of the Platonist elements that others have discerned in DeGrav, especially Newton’s commitment to doctrines of different degrees of reality as well as the manner in which the first existing being ‘transfers’ its qualities to space (as a kind of causa-sui). This can clarify the conceptual relationship between space and its formal cause in Newton as well as Newton’s commitment to the spatial extended-ness of all existing beings. While the first two sections of this paper engage with existing scholarly controversies, in the final section the paper argues that the recent focus on emanation has obscured the importance of Newton’s very interesting claims about existence and measurement in “DeGrav”. The paper argues that according to Newton God and other entities have the same kind of quantities of existence; Newton is concerned with how measurement clarifies the way of being of entities. Newton is not claiming that measurement reveals all aspects of an entity. But if we measure something then it exists as a magnitude in space and as a magnitude in time. This is why in DeGrav Newton’s conception of existence really helps to “lay truer foundations of the mechanical sciences.”

What makes for a philosophical classic? Why do some philosophical works persist over time, while others do not? The philosophical canon and diversity are topics of major debate today. This stimulating volume contains ten new essays by accomplished philosophers writing passionately about works in the history of philosophy that they feel were unjustly neglected or ignored-and why they deserve greater attention. The essays cover lesser known works by famous thinkers as well as works that were once famous but now only faintly remembered. Works examined include Gorgias' Encomium of Helen, Jane Adams' Women and Public Housekeeping, W.E.B. DuBois' Whither Now and Why, Edith Stein's On the Problem of Empathy, Jonathan Bennett's Rationality, and more. While each chapter is an expression of engagement with an individual work, the volume as a whole, and Eric Schliesser's introduction specifically, address timely questions about the nature of philosophy, disciplinary contours, and the vagaries of canon formation.

David Hume's philosophy, especially the positive project of his science of man, is often thought to be modeled on Newton's successes in natural philosophy. Hume's self-described experimental method (see the subtitle to Treatise) and the resemblance of his rules of reasoning (Treatise, 1.3.15)1 with Newton's are said to be evidence for this position (Noxon 1973; De Pierris 2002). Hume encourages this view of his project by employing Newtonian metaphors: he talks of an attraction in the mental world on a par with that in the natural world (1.1.4.6). Hume infers the existence of habits as a kind of mental force (EHU 5.2.2) analogous to gravity; the discovery of the the principles of association, which in thehe calls his most important achievement see the section on Association in the entry on Hume in this Encyclopedia, are, then, analogous to the laws of motion. Hume certainly appears to want his readers to feel that he is modeling his project on the successes of natural philosophy, exemplified by Newton. In the Introduction to the Treatise and even more explicitly in the opening pages of EHU (1.15), Hume suggests that his science of man can parallel recent achievements in natural philosophy (with rather obvious nods to Newton's successes in planetary astronomy). And at the start of EPM, he echoes Newton's rejection of hypotheses (1.10). There is, thus, no doubt that Hume wants his readers to believe that Newton forms a kind of model

In this paper I offer three main challenges to James (2011). All three turn on the nature of philosophy and secure knowledge in Spinoza. First, I criticize James's account of the epistemic role that experience plays in securing adequate ideas for Spinoza. In doing so I criticize her treatment of what is known as the ‘conatus doctrine’ in Spinoza in order to challenge her picture of the relationship between true religion and philosophy. Second, this leads me into a criticism of her account of the nature of philosophy in Spinoza. I argue it is less piecemeal and less akin to what we would recognize as ‘science’ than she suggests. Third, I argue against James's core commitment that Spinoza's three kinds of knowledge differ in degree; I claim they differ in kind. My argument will offer a new interpretation of Spinoza's conception of ‘common notions’. Moreover, I argue that Spinozistic adequate knowledge involves something akin to angelic disembodiment

n recent years, there has been a resurgence of academic interest in Adam Smith. As a consequence, a large number of PhD dissertations on Smith have been written by international scholars - in different languages, and in many diverse disciplines, including economics, women’s studies, philosophy, science studies, political theory and english literature: diversity which has enriched the area of study. In response to this activity, and in order to making these contributions more easily accessible to other Smith scholars, Leonidas Montes and Eric Schliesser have edited this important new book. Of interest to Smith scholars and those interested in the history of economic thought in general, the contributions to this book are self-consciously interdisciplinary and skilfully employ many different methodologies.

I call attention to Berkeley’s treatment of a Newtonian indispensability argument against his own main position. I argue that the presence of this argument marks a significant moment in the history of philosophy and science: Newton’s achievements could serve as a separate and authoritative source of justification within philosophy. This marks the presence of a new kind of naturalism. A long the way, I argue against the claim tha t there is no explicit opposition or distinction between “philosophy” and “science” until the nineteenth century. Finally, I argue for the conceptual unity between Berkeley’s immaterialism and instrumentalism. I argue that Berkeley’s commitment to immaterialism requires his reinterpretation of science and, thus, the adoption of instrumentalism.

This paper focuses on Warren Nutter’s The Extent of Enterprise Monopoly in the United States, 1899-1939. This started out as a (1949) doctoral dissertation at The University of Chicago, part of Aaron Director’s Free Market Study. Besides Director, O.H. Brownlee and Milton Friedman were closely involved with supervising it. It was published by The University of Chicago Press in 1951. In the 1950s the book was explicitly understood as belonging to the “Chicago School” (Dow and Abernathy 1963). By articulating the content, context, and reception of Nutter’s monograph, this paper discusses four larger themes. First, I introduce the importance of Kuhnian conceptions of science to the methodological and institutional understanding of economics in the development of a ‘Chicago’ school of economics. I do this in context of previously unpublished Stigler-Kuhn exchange. While Thomas Kuhn was widely read and adopted in the social sciences and humanities in the 1960s and 70s (and thereafter), I argue that at ‘Chicago,’ proto-Kuhnian language can be found going back to the 1940s; in those early days it is partly used to disparage the achievements of economic theorizing as promoted by others. A more self-congratulatory Kuhnian self-understanding of economics as a mature paradigm starts to get adopted around 1955 by George Stigler. One important new claim is that the later Kuhnian language gets adopted in part to divest ‘Chicago’ from its shared roots with Institutionalist economics. So, this paper contributes to a better understanding of the formation of a shared narrative at ‘Chicago.’ Second, I introduce contextual themes from Milton Friedman’s writings in the late 40s and 50s to help us understand the nature of realism at Chicago. Nutter’s dissertation helps in reading and illuminating Milton Friedman’s famous 1953 methodology paper in historical and intellectual context. Third, while this chapter notes some of the political ramifications of Chicago economics, my main aim is to help explain the manner in which Chicago attempted to chart a distinctive methodological course. This methodology has often been described as Marshallian with debts to the large-scale NBER studies. Rather than going over familiar territory, I call attention to the importance of proxies in Nutter’s empirical methodology. It is an unappreciated feature of the inductive, quantitative method that focused on the component structures of the economy that characterizes Chicago’s methodological outlook in this period. I show this by comparing Nutter’s dissertation to work done by Stigler, then at Columbia. We know from Stigler’s correspondence with Friedman that in this period they discussed methodological matters. What is less well known is that Friedman is explicitly credited for Stigler’s methodological insights in Stigler's Five Lectures at LSE. The fifth lecture, “Competition in the United States,” covers similar territory as Nutter’s project. Comparing the work by Stigler and Nutter sheds light on the nature of Chicago methodology as it was being developed away from foundations laid by Frank Knight and Henry Simons in the late 1940s and 1950s and opening up the door to (right wing) social engineering as exemplified by Harberger. I present my analysis through the published critical reception of both works among economists. A fourth reason to focus on Nutter’s dissertation is that it was featured in a Fortune magazine article in January 1952. So, it provides a useful entry into how politically important ‘Chicago’ research was marketed to a wider audience. This connects to issues explored by Phil Mirowski and his students, Rob van Horn and Eddie Nik-kah. So, Nutter’s dissertation can help us see how ‘sponsored’ research looks at ‘Chicago at the time. This is especially important because it has been claimed that Director’s Free Market Study group promoted a change from classically liberal views on monopoly, which condemned labor and employer monopolies, to a more pro-business stance.

In this article, the author offers a discussion of the evidential role of the Galilean constant in the history of physics. The author argues that measurable constants help theories constrain data. Theories are engines for research, and this helps explain why the Duhem-Quine thesis does not undermine scientific practice. The author connects his argument to discussion of two famous papers in the history of economic methodology, Milton Friedman's 'Methodology of Positive Economics', which appealed to example of Galilean Law of Fall in its argument; and Vernon Smith's 'Economics in the Laboratory'. While the author offers some criticism of Friedman and Smith, most of the article is a friendly reinterpretation of their insights.

Adam Smith is rediscovered every few generations by philosophers surprised by his subtlety, originality, and relevance. Smith’s status as mythical father of economic science and his role as canonical defender of free trade is secure within economics, but few philosophers have been more often misrepresented and underestimated. Because he is well known as an advocate of commercial society, many scholars, public intellectuals, commentators, and journalists are happy to implicate him automatically in its successes and failures, or to enlist him in one side or another of the various ideological battles surrounding the utility and dangers of market economics. This book is an accessible and engaging introduction to Smith’s most important contributions to philosophy. Beginning with an introductory chapter on Smith’s life, writings and readings, Eric Schliesser locates Smith in his immediate social and philosophical context. Later chapters analyse key concepts in his core moral, political and metaphysical theories, before turning to Smith's contribution to areas of ongoing philosophical interest, especially philosophy of science, and the metaphysics of mind and self. Schliesser concludes by summarising Smith's complicated legacy in the eighteenth, nineteenth, and twentieth centuries, and explores how Smith is being 're-discovered' in contemporary moral philosophy.

In this paper I revisit Adam Smith’s treatment of Copernicanism and Newtonianism in his essay, “The History of Astronomy” (hereafter: “Astronomy”), in light of a surprisingly ignored context: David Hume. This remark will strike most scholars of Adam Smith as unfounded—David Hume’s philosophy is often invoked as a source of Smith’s approach in the “Astronomy” or as its target. Yet, Hume’s occasional remarks on Copernicanism nor his treatment of the history of science in the History of England (1754-62, but revised throughout Hume’s life) have not been carefully analyzed in light of the “Astronomy.” In the first five sections of this paper I offer a detailed analysis of all of Hume’s remarks on the Copernican system in his oeuvre. I show that David Hume believed that Copernicus achieved a “revolution” in philosophy. Moreover, I argue that Hume increasingly treats Galileo as the hero of the Copernican revolution. In doing so, Hume appears surprisingly blind to the importance of post-Galilean natural philosophy, especially the (dynamical) arguments that Huygens and Newton provided for the rotation of the Earth. In the last section of the paper, I argue that Adam Smith does show appreciation of dynamic views. I show that Smith and the mature Hume agree on the importance of Galileo, even describing his method in strikingly similar language, but that they evaluate the evidence differently in light of two conflicting commitments: i) Hume is committed to the “true philosophy”—-a certain kind of scepticism which Smith does not share; ii) Hume never seems to have assimilated the way Newton changed the evidential standards within science.

This chapter explains what Isaac Newton means with the phrase “absolute, true, and mathematical time” in order to discuss some of the philosophic issues that it gives rise to. It describes Newton's thought in light of a number of scientific, technological, and metaphysical issues that arose in seventeenth‐century natural philosophy. The first section discusses some of the relevant context from the history of Galilean, mathematical natural philosophy, especially as exhibited by the work of Christiaan Huygens. The second section offers a close reading of what Newton says about time in the Principia's Scholium to the definitions. It argues that Newton allows us to conceptually distinguish between “true” and “absolute” time from the vantage point of Newton's dynamics. The third section, in the context of a brief account of Descartes' views on time, discusses the material that Newton added to the second edition of the Principia in the General Scholium.
