    Infinite analysis, lucky proof, and guaranteed proof in Leibniz
    Archiv für Geschichte der Philosophie 93 (2): 222-236. 2011.
    According to one of Leibniz's theories of contingency a proposition is contingent if and only if it cannot be proved in a finite number of steps. It has been argued that this faces the Problem of Lucky Proof , namely that we could begin by analysing the concept ‘Peter’ by saying that ‘Peter is a denier of Christ and …’, thereby having proved the proposition ‘Peter denies Christ’ in a finite number of steps. It also faces a more general but related problem that we dub the Problem of Guaranteed Pr…Read more

    Heidegger on the Being of Monads: Lessons in Leibniz and in the Practice of Reading the History of Philosophy
    British Journal for the History of Philosophy 23 (6): 1169-1191. 2015.
    This paper is a discussion of the treatment of Leibniz's conception of substance in Heidegger's The Metaphysical Foundations of Logic. I explain Heidegger's account, consider its relation to recent interpretations of Leibniz in the Anglophone secondary literature, and reflect on the ways in which Heidegger's methodology may illuminate what it is to read Leibniz and other figures in the history of philosophy

    Theodicy, Metaphysics, and Metaphilosophy in Leibniz
    Philosophical Topics 43 (1-2): 27-52. 2015.
    In this paper I offer a discussion of chapter 3 of Adrian Moore’s The Evolution of Modern Metaphysics, which is titled “Leibniz: Metaphysics in the Service of Theodicy.” Here Moore discusses the philosophy of Leibniz and comes to a damning conclusion. My main aim is to suggest that such a conclusion might be a little premature. I begin by outlining Moore’s discussion of Leibniz and then raise some problems for the objections that Moore presents. I follow this by raising a Moore-inspired problem …Read more

    Leibniz's Mill Argument Against Mechanical Materialism Revisited
    Ergo: An Open Access Journal of Philosophy 1. 2014.
    Section 17 of Leibniz’s Monadology contains a famous argument in which considerations of what it would be like to enter a machine that was as large as a mill are offered as reasons to reject materialism about the mental. In this paper, I provide a critical discussion of Leibniz’s mill argument, but, unlike most treatments, my discussion will focus on texts other than the Monadology in which considerations of the mill also appear. I provide a survey of three previous interpretations of the argume…Read more

    According to Robert Sleigh Jr., “The opening remarks of DM.18 make it clear that Leibniz took the results of DM.17 as either establishing, or at least going a long way toward establishing, that force is not identifiable with any mode characterizable terms of size, shape, and motion.” Sleigh finds this puzzling and suggests that other commentators have generally been insufficiently perplexed by the bearing that the DM.17 has on the metaphysical issue. In this brief paper, I examine the solution t…Read more

    In a recent paper, Dennis Plaisted examines an important argument that Leibniz gives for the existence of primitive concepts. After sketching a natural reading of this argument, Plaisted observes that the argument appears to imply something clearly inconsistent with Leibniz’s other views. To save Leibniz from contradiction, Plaisted offers a revision. However, his account faces a number of serious difficulties and therefore does not successfully eliminate the inconsistency. We explain these diff…Read more

    Seine Kritik an Descartes' Auffassung vom Körper gründet Leibniz bekanntlich auf Erörterungen zur Teilbarkeit und Ausdehnung. Obgleich jene Argumentation im Fokus einer Auseinandersetzung mit Leibniz' Metaphysik angesiedelt werden muss, ist sie bisher nicht recht verstanden worden. Mein Anliegen hier ist im Kern, Leibniz' Gedankengang zu explizieren und dessen Stichhaltigkeit auszuleuchten. Das Argument, um das es geht, ist wohl am ehesten aus der Darlegung in Leibniz' Korrespondenz mit Antoine …Read more

    In 1985 Daniel Garber published his highly intluential paper “Leibniz and the Foundations of Physics: The Middle Years”. In two recent articles, Garber returns to these issues with a new position - that we should perhaps conclude that Leibniz did not have a view concerning the ultimate ontology of substance during his middle years. I discuss the viability of this position and consider some more general methodological issues that arise from this discussion.

    Stepping Back Inside Leibniz’s Mill
    with Marc Bobro
    The Monist 81 (4): 553-572. 1998.
    Leibniz’s reasons for rejecting materialism are complex and often rely on assumptions that are deeply puzzling to contemporary philosophers. However, the discussion of these issues in § 17 of the Monadology has received a lot of attention over the past couple of decades. For it is here that Leibniz presents the most well known version of his “mill argument.”

    Leibniz, Bayle, and Locke on Faith and Reason
    with Ben Crowe
    American Catholic Philosophical Quarterly 76 (4): 575-600. 2002.
    This paper illuminates Leibniz’s conception of faith and its relationship to reason. Given Leibniz’s commitment to natural religion, we might expect his view of faith to be deflationary. We show, however, that Leibniz’s conception of faith involves a significant non-rational element. We approach the issue by considering the way in which Leibniz positions himself between the views of two of his contemporaries, Bayle and Locke. Unlike Bayle, but like Locke, Leibniz argues that reason and faith are…Read more

    Leibniz's notion of an aggregate
    British Journal for the History of Philosophy 9 (3). 2001.

    In discussion of Leibniz’s philosophical methodology Donald Rutherford defends the view that Leibniz regarded metaphysics as an a priori demonstrative science. In the course of this discussion Rutherford isolates and tries to deflect a significant challenge for his view, namely the observation that in many of his mature writings on metaphysics Leibniz appears to defend his views by means of a posteriori arguments. I present some prima facie difficulties with Rutherford’s position and then offer …Read more

    The debate over extended substance in Leibniz's correspondence with de Volder
    International Studies in the Philosophy of Science 15 (2). 2001.
    Between 1698 and 1706 Leibniz was engaged in one of his most interesting correspondences, with the Dutch philosopher and physicist Burcher de Volder. The two men were concerned primarily with the question of how the motion of bodies can be explained without appeal to the direct intervention of God. Leibniz presented a naturalistic account of motion to De Volder, but failed to convince him of its adequacy. I shall examine one reason for this failure - the disagreement that arose over the issue of…Read more

    Leibniz’s Philosophical Dream of Rational and Intuitive Enlightenment
    Dialogue and Universalism 32 (1): 203-219. 2022.
    This paper is a new translation and interpretation of the essay by Leibniz which has come to be known as “Leibniz’s Philosophical Dream.” Leibniz used many different literary styles throughout his career, but “Leibniz’s Philosophical Dream” is unique insofar as it combines apparent autobiography with a dreamscape. The content is also somewhat surprising. The essay is reminiscent of Plato, insofar as Leibniz describes a transition from existence in a cave to a more enlightened mode of being outsi…Read more

    True and False Mysticism in Leibniz
    The Leibniz Review 25 55-87. 2015.
    The question of Leibniz’s relationship to mysticism has been a topic of some debate since the early part of the 20th Century. An initial wave of scholarship led by Jean Baruzi presented Leibniz mystic. However, later in the 20th Century the mood turned against this view and this negative appraisal holds sway today. In this paper I aim to do two things: First I provide a detailed account of the ways in which Leibniz is critical of mysticism; second, I argue that there is, nonetheless, an importan…Read more

    Leibniz and His Correspondents (edited book)
    Cambridge University Press. 2004.
    Unlike most of the other great philosophers Leibniz never wrote a magnum opus, so his philosophical correspondence is essential for an understanding of his views. This collection of essays by pre-eminent figures in the field of Leibniz scholarship is a most thorough account of Leibniz's philosophical correspondencee. It both illuminates Leibniz's philosophical views and pays due attention to the dialectical context in which the relevant passages from the letters occur. The result is a book of en…Read more

    Leibniz Microfilms at the University of Pennsylvania
    The Leibniz Review 6 164-169. 1996.
    Thanks to the efforts of Paul Schrecker and John W. Nason some half century ago, the University of Pennsylvania is home to microfilm reproductions of over one hundred thousand hand-written pages drawn from the collection of Leibniz’s papers presently housed in the Niedersächsische Landesbibliothek, Hannover. The microfilms are to be found on the mezzanine floor of the reference section in the Van Pelt Library and are readily accessible to visitors. Xerox copies may be made, although the Van Pelt…Read more

    Leibniz’s Philosophy as a Way of Life?
    Metaphilosophy 51 (2-3): 259-279. 2020.
    The main concern of this essay is to make a case for the thesis that Leibniz conceived of his philosophy as a way of life in something like the sense articulated in the works of Pierre Hadot. On this view, philosophy was a type of conduct, or a mode of existing‐in‐the‐world, which had to be practised at each instant, with the goal of transforming the whole of the individual’s life. The essay also serves as an introduction to some of the main themes in Hadot’s work. While it includes a brief disc…Read more

    The aim of this paper is to shed light on Leibniz’s justification of the Principle of Sufficient Reason. It approaches this issue through a close textual analysis of the correspondence with Samuel Clarke and a more abstruse and lesser-known writing, ‘Leibniz’s Philosophical Dream’.

    This volume is a critical edition of the eight-year correspondence between Gottfried Wilhelm Leibniz and Burcher de Volder, professor of philosophy and mathematics at Leiden University. Containing the surviving correspondence between Leibniz and De Volder, the volume also presents a generous selection from the letters between Leibniz and his friend Johann Bernoulli, through whose intercession the correspondence began. Bernoulli acted as intermediary throughout, and the often candid discussions b…Read more
