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 call attention to Adam Smith’s “Considerations Concerning the First Formation of Languages” in order to facilitate understanding Adam Smith from a Darwinian perspective. By ‘Darwinian’ I mean a position that explains differential selection over time through natural mechanisms. First, I argue that right near the start of Wealth of Nations Smith signals that human nature has probably evolved over a very long amount of time. Second, I connect this evidence with an infamous passage on infanticide in The Theory of Moral Sentiments in order to argue that Smith is committed to group selection. Third, I argue that in Dissertation on Languages one can find building blocks for the claim that mind and language co-develop over time. More controversially I claim that in TMS there is a distinction between natural sentiments and moral sentiments. Natural sentiments are evolved (presumably through cultural selection) and moral sentiments are developed (through acculturation within society). Along the way, I argue that this distinction would have improved Darwin’s Descent of Man by blocking a move toward eugenics.

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 (Scottish and European) and philosophical (Hume, Hutcheson, Mandeville, Rousseau, Montesquieu, Butler, Hobbes, Spinoza, Newton, Voltaire) context. Later chapters analyse key concepts in his core moral, political and metaphysical theories (sympathy, self-interest, division of labor), 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.

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.

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.”

In this paper, I argue that major elements of Hume’s metaphysics and epistemology are not only directed at the inductive argument from design which seemed to follow from the success of Newton’s system, but also have far larger aims. They are directed against the authority of Newton’s natural philosophy; the claims of natural philosophy are constrained by philosophic considerations. Once one understands this, Hume’s high ambitions for a refashioned ‘true metaphysics’ or ‘first philosophy’, that is, Hume’s ‘Science of Human Nature’, can be seen and evaluated in their proper light. Hume has three motives for his attack on Newton: his work is informed by and gives cover to superstitious beliefs; his project is not useful to the public; and its success generates a challenge to the independent authority of philosophy. This essay consists of five sections. First, I discuss Hume’s attitude toward Newton. Newton claims that natural philosophy should be the foundation for other sciences, while in the ‘Introduction’ to the Treatise Hume asserts the supremacy of the ‘science of man’. For Hume the human sciences can attain the high epistemic status of ‘proof’, while much of the physical sciences must do with lower forms of ‘probability’. Furthermore, Hume’s ‘rules by which to judge of causes and effects’ do not replicate Newton’s fourth Rule; this opens a gap between the ontologies and methodologies of Newton and Hume. Moreover, Hume’s account of causation is designed to undercut the reductionist bias of natural philosophy. According to Hume the parts of natural sciences that go beyond common life can be evaluated from the point of view of the science of man. I end with remarks on the philosophic origins and significance of Hume’s attack on Newton’s natural philosophy. I depart from two independent traditions of interpreting Hume. One tradition makes many references to Newton’s influence on Hume. On a more detailed level, proponents of this view may call attention to Hume’s ‘rules’, his ‘Experiments’ and ‘Anatomy’, his method of investigation, the application of Newtonian metaphors works (e.g., an ‘attraction’ in the ‘mental world’ on a par with that in the ‘natural world’ – the principles of association are, then, analogous to the laws of motion). Hume’s ‘science of man’ is said to be inspired by Newton’s science of nature. Hume wants 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 more explicitly in the opening pages of EHU, Hume suggests that his ‘science of man’ can parallel recent achievements in natural philosophy (especially planetary astronomy). Thus, my claim is not that Newton did not figure importantly in Hume’s philosophy, but, instead, that Hume’s project is in many respects more hostile to Newton’s achievements – as available to well-informed eighteenth-century readers – than many recent interpreters have realized. There is a different tradition that argues Hume simply did not understand Newton. Hume’s philosophy, thus, cannot do justice to Newtonian science. Hume’s lack of mathematical competence is said to be a barrier to his understanding of Newton’s mathematical natural philosophy. One finds this attitude behind the cranking of Bayesian machinery in John Earman’s attack on Hume’s treatment ‘Of Miracles’. However, this tradition begs the question; it takes the authority of ‘science’ for granted in Hume. Against this second tradition I argue that Hume did understand salient features of Newton’s methodology and position, although in ways often unappreciated by the first tradition mentioned above. For example, in his comments on Newton in the History of England, Hume discerns the (broad) outlines of Newton’s commitment to the method of analysis and synthesis (see Newton’s Opticks, Query 31) and how it differs from Boyle’s methodology. So, Hume has a subtle understanding of Newton’s methodology – even if one were to grant that he lacks appreciation of the role of mathematics in Newton’s natural philosophy. Leaving open the question whether Hume understood all the details of Newton’s system, Hume’s departures from Newton are best interpreted not as ‘ironic’, but as philosophically motivated.
