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

This paper offers a composite portrait of the concept of magnanimity in nineteenth-century America, focusing on Ralph Waldo Emerson, Margaret Fuller, and Henry David Thoreau. A composite portrait, as a method in the history of philosophy, is designed to bring out characteristic features of a group's philosophizing in order to illuminate characteristic features that may still resonate in today's philosophy. Compared to more standard methods in the historiography of philosophy, the construction of a composite portrait de-privileges the views of individual authors. These philosophers saw the virtue of magnanimity as a remedy for a number of modern ills. American philosophers suggest that the best sort of magnanimity is acquired by adopting the correct relation to the natural world, including new forms of inquiry, or by adopting a life of voluntary poverty. Magnanimous individuals are critics of capitalism and offer themselves as exemplars of a better, experimental life.

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.

Chapter one is an introduction. In chapter two, I argue that, due to a lack of knowledge of Newton, Hume is unable to use the "Science of Man" to provide a foundation for the other sciences. Hume's account of causality and the missing shade of blue receive special attention. Hume tries, without paying attention to scientific practice, to constrain what science can be about. ;In chapter three, I reconstruct Adam Smith's epistemology. The major theoretical concept of Smith's moral psychology, the "Impartial Spectator," illuminates his views on the articulation and reception of scientific theories; it brings out the open-ended, social and norm-governed nature of science. Sentiments motivate inquiry, but adopting its results can still be reasonable. After Newton, Smith is not a skeptic, but a realist. ;In chapter four, I explain Smith's methodology in Wealth of Nations . Smith employs a model to enable observed deviations from expected regularities to uncover genuine social causes and aid in improving theory in a potentially open-ended process of successive approximation. I draw on The History of Astronomy where Smith attacks Descartes for trying to explain away deviations from general rules. ;In Chapter five, I explain the political aims of Smith's WN. Smith is an Incremental Redistributionist . Smith's reform proposals and the values that guide his theorizing are in aid of the working poor. I attack a possible political counter-argument against this by attending to Smith's historical understanding of property; Smith's defense of property rights, following Hume's critique of Locke, is by no means absolute. Yet, Smith's appeals to "humanity" appear without justification in WN. ;In chapter six, I investigate the purpose of philosophy in commercial society. In the debate between Rousseau and Hume on philosophic self-understanding, between self-sufficiency and independence, Smith sides with the latter. Smith emphasizes, however, that once basic needs are met, friendship among equals is a more valuable than wealth; it provides happiness and is within every one's reach. Philosophers can enjoy immortality after death if they attempt to be benefactors to humanity, but Smith believes that philosophic friendship is its own and highest reward

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 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.

Sophie de Grouchy: The Tradition of Two Liberties and the Missing Mother of LiberalismIn this paper, I treat Sophie de Grouchy as an important contributor to liberal reflection on the famous distinction between two kinds of liberty. I place her in the intellectual context of Adam Smith and Jean-Jacques Rousseau, and show it is likely that Benjamin Constant was familiar with her work. Along the way, by engaging with Isaiah Berlin and with Jason Stanley and Vesla Weaver, I make some suggestions on the nature of an intellectual tradition worth having.

In this collection of new and previously published essays, noted philosopher Eric Schliesser offers new interpretations of the signifance of Isaac Newton's metaphysics on his physics and the subsequent development of philosophy more broadly. In particular, he explores the rich resonances between Newton's and Spinoza's metaphysics. The volume includes a substantive introduction, new chapters on Newton's modal metaphysics and his theology, and two postscripts in whichSchliesser responds to some of his most important critics, including Katherine Brading, Andrew Janiak, Hylarie Kochiras, Steffen Ducheyne, and Adwait Parker. The collection provides new and varied analyses on familiar focuses of Newton's work, adding important perspectives to the recent revival ofinterest in Spinoza's metaphysics.

This paper argues that a debate between Toland and Clarke is the intellectual context to help understand the motive behind the critic and the significance of Berkeley's response to the critic in PHK 60-66. These, in turn, are responding to Boyle's adaptation of a neglected design argument by Cicero. The paper shows that there is an intimate connection between these claims of natural science and a once famous design argument. In particular, that in the early modern period the connection between the scientific revolution and a certain commitment to final causes, and god's design, is more than merely contingent. The details of PHK 60-66 support the idea that the critic is responding to concerns that by echoing features of Toland's argument Berkeley undermines the Newtonian edifice Clarke has constructed.

This paper shows that Locke anticipates key features of Hume's more celebrated analysis of convention. It does so by developing Lenz's account of Lockean (linguistic) convention and its normativity, as presented in Socializing Minds. Locke's account of linguistic convention shares structural features also visible in Locke's treatment of the convention of money and property. The paper shows that Locke's ‘Humean' account of convention responds to a lacuna in Pufendorf’s treatment of linguistic convention that Lenz argues is significant to Locke.
