    Schon in seinen frühen Jahren war Leibniz ein Gegner der Cartesischen Naturphilosophie, ca. 1697 zeigt sich in seinen Texten dann ein Argument gegen Descartes, das ich im folgenden behandle und als ,heterogeneity argument‘ bezeichnen möchte - eingangs wird hier dargestellt, wie Leibniz es im Paragraphen 13 seiner Schrift De ipsa natura expliziert, anschließend diskutiere ich zwei frühere Ansätze, die sich um das Thema drehen und die darin einig sind, daß Leibniz Descartes' Auffassung von der mat…Read more

    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

    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

    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

    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

    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
