Locke's Essay, Book I: The Question-Begging Status of the Anti-Nativist Arguments

In this paper I argue against the received view that the anti-nativist arguments of Book I of Locke's Essay conclusively challenge nativism. I begin by reconstructing the chief argument of Book I and its corollary arguments. I call attention to their dependence on (what I label) "the Awareness Principle", viz. , the view that there are no ideas in the mind of which the mind either isn't currently aware or hasn't been aware in the past. I then argue that the arguments' dependence on this principle is question begging on two counts. Unless this principle is defended, Locke's arguments beg the question against Descartes and Leibniz because their nativism implies the denial of the Awareness Principle. And even when Locke defended the principle, his arguments remain question begging because they presuppose the empiricism they aim to prove. The disclosure of the question-begging status of these arguments debunks a seemingly powerful way of attacking nativism.     

Properties,laws, and worlds

Jonathan Schaffer argues against a necessary connection between properties and laws. He takes this to be a question of what possible worlds we ought to countenance in our best theories of modality, counterfactuals, etc. In doing so, he unfairly rigs the game in favor of contingentism. I argue that the necessitarian can resist Schaffer’s conclusion while accepting his key premise that our best theories of modality, counterfactuals, etc. require a very wide range of things called ‘possible worlds’. However, the necessitarian can and should insist that, in many cases, these worlds are not metaphysically possible. I will further argue that, having taken such a stance, the necessitarian has additional resources to respond to Schaffer’s other arguments against the view.     

Descartes,Malebranche and Leibniz: conceptions of substance in arguments for the immateriality of the soul

ABSTRACT

The most prominent early modern argument against materialism is to be found in Descartes. Previously I had argued that this argument relies crucially on a robust conception of substance, according to which it has a single principal attribute of which all its other intrinsic qualities are modes. In the present paper I return to this claim. In Section 2, I address a question that is often raised about that conception of substance: its commitment to the idea that a substance has a single such principal attribute. Gonzalo Rodriguez-Pereyra and Daniel Garber have argued that this claim relies on Descartes's identification of substance with attribute. But I argue that it relies on his view that a substance has a single, unitary nature. In Section 3, I examine the role of this conception of substance in arguments found in Malebranche and Leibniz and compare these arguments with Descartes's.     

Toleration and Pragmatism: Themes from The Work of John Horton

John Horton’s work has been particularly influential in debates on specific topics related to toleration, political obligation, modus vivendi and political realism. More recently, he has synthesised these views in the form of a distinctive position in political philosophy, a position that has the potential to question much of the received wisdom in the field. The papers of this special issue engage with some of the most fundamental issues of Horton’s account, more exactly, the related issues of toleration and modus vivendi, Horton’s account of associative obligations, with a focus on the methodological assumptions which underpin his position more generally, and the metaphysical presuppositions of his account, in particular, the presupposition of contingency. I offer brief presentations of the papers in the special issue and of the ways they link with each other. In the discussion of the papers by Forst, Newey, Jones, Weale and Mendus, the emphasis will be on those arguments which question Horton’s position. Horton’s paper will then be presented with a focus on possible responses to these challenges. I will conclude with several remarks on an unexpected continuity between Horton’s realist view and a view realists usually criticise as idealising, namely, John Rawls’s theory of justice as fairness.     

Morality and the market in blood

ABSTRACT The late Richard Titmuss made a persuasive case against allowing the sale of human blood in his book, The Gift Relationship. His arguments have been developed further by Peter Singer in recent articles. While the issues of quantity and quality of blood under market and non-market systems have received much attention, the moral and political aspects of the Titmuss-Singer case have gone relatively unexamined. First, I question their claim that a donation-only system promotes greater freedom, which rests on a confusion of liberty and opportunity. Next, I consider reasons for doubting their view that altruism is fostered significantly more under the non-market approach. Finally, I survey recent developments in the quantity-quality debate and possible implications of the blood controversy for national health care.     

The debate over extended substance in Leibniz's correspondence with De Volder

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 whether there is a substance whose nature is constituted by extension.     

Making history philosophical: Kant,Maimon, and the evolution of the historiography of philosophy in the critical period

ABSTRACT

In this article I explore Maimon’s role in the evolution of Kant’s understanding of the function of the history of philosophy in philosophical enquiry. Kant is often viewed as holding an ambivalent relation to the history of philosophy. On the one hand, he dismisses past philosophers as victims of transcendental illusion and downplays the value of the historiography of philosophy. On the other hand, by framing his project as a synthesis of several philosophical traditions, Kant embeds the critical philosophy into a sweeping historical narrative in a manner that highlights the importance of the past for present philosophical aims. In this article, I argue that for most of his career Kant held a position reflective of the former view, but that the publication of Maimon’s response to a prize question announced by the Royal Academy led Kant to develop an understanding of the history of philosophy more in line with the latter view. The result is a distinctively post-Kantian model for a ‘philosophical history of philosophy’ that is both methodologically nuanced and potentially relevant to contemporary debates.     

Max Scheler,cousin of disjunctivism

Disjunctivism has triggered an intense discussion about the nature of perceptual experience. A question in its own right concerns possible historical antecedents of the position. So far, Frege and Husserl are the most prominent names that have been mentioned in this regard. In my paper I shall argue that Max Scheler deserves a particularly relevant place in the genealogy of disjunctivism for three main reasons. First, Scheler’s view of perceptual experience is distinctively disjunctivist, as he explicitly argues that perceptions and hallucinations differ in nature. Second, his version of the position is philosophically interesting in its own right. This is so primarily, though not exclusively, in virtue of the positive story he tells us about perceptual content. Third, Scheler’s case proves particularly instructive to the question of whether intentionalism and disjunctivism constitute a fundamental, unbridgeable divide.     

Moral Evil and Leibniz’s Form/Matter Defense of Divine Omnipotence

The purpose of this paper is to demonstrate that Leibniz’s form/matter defense of omnipotence is paradoxical, but not irretrievably so. Leibniz maintains that God necessarily must concur only in the possibility for evil’s existence in the world (the form of evil), but there are individual instances of moral evil that are not necessary (the matter of evil) with which God need not concur. For Leibniz, that there is moral evil in the world is contingent on God’s will (a dimension of divine omnipotence), with the result that even though it is necessary that God exerts his will, there are particular products of his will that are contingent and unnecessary—including human moral evil. If there are instances of evil which are contingent on God’s will and yet unnecessary, then the problematic conclusion for Leibniz’s view must be that human evil depends upon divine concurrence, not just for its possibility in the world (which is necessary) but for its instance (which is contingent). If the form/matter defense of omnipotence contains a true paradox, then God concurs in the form as well as the matter of evil. To assuage this difficulty for Leibniz, I will argue that he could either give up an Augustinian notion of evil, or rely upon a distinction between *potenta absoluta* and *potenta ordinate*, which was popular among important thinkers in the medieval period.     

Leibniz's Twofold Gap Between Moral Knowledge and Motivation

Moral rationalists and sentimentalists traditionally disagree on at least two counts, namely regarding the source of moral knowledge or moral judgements and regarding the source of moral motivation. I will argue that even though Leibniz's moral epistemology is very much in line with that of mainstream moral rationalists, his account of moral motivation is better characterized as sentimentalist. Just like Hume, Leibniz denies that there is a necessary connection between knowing that something is right and the motivation to act accordingly. Instead, he believes that certain affections are necessary for moral motivation. On my interpretation, then, Leibniz is an externalist about judgements and motivation: he is committed to a gap between the judgement that something is morally right and the motivation to act accordingly. As a matter of fact, I will argue that there are two gaps. The first and less controversial one has to do with the fact that Leibniz reconciles his psychological egoism with ethical altruism through his account of love. The second gap between moral judgements and motivation is a more fundamental one: Leibniz denies that there are any necessary connections between beliefs and motivation, or even more generally, between perceptions and appetitions.     

THE DEFENCE OF THE MYSTERIES OF THE TRINITY AND THE INCARNATION: AN EXAMPLE OF LEIBNIZ'S 'OTHER' REASON

In this paper I will discuss certain aspects of Leibniz's theory and practice of ‘soft reasoning’ as exemplified by his defence of two central mysteries of the Christian revelation: the Trinity and the Incarnation. By theory and practice of ‘soft’ or ‘broad’ reasoning, I mean the development of rational strategies which can successefully be applied to the many areas of human understanding which escape strict demonstration, that is, the ‘hard’ or ‘narrow’ reasoning typical of mathematical argumentation.¹ These strategies disclose an ‘other’ reason, i.e. a complementary set of arguments and methods developed by Leibniz in order to deal with crucial issues such as the ‘weighting’ of probabilities and truths of fact. I will argue that one of the most compelling examples of the importance and fertility of Leibniz's ‘other’ reason is provided by his solution to the problems posed by the unique epistemological status of theological mysteries.     

On Kant’s Knowledge of Leibniz’ Metaphysics—a Reply to Garber

Daniel Garber has put forward an argument that aims to show that Kant’s understanding of Leibniz’ metaphysics should be discounted because he could only have had access to a small and narrow sample of Leibniz’ works from around 1710–1714. In particular, Garber argues that as Kant could not have read Leibniz’ correspondence with Arnauld or his correspondence with Des Bosses he could not have had an adequate conception of Leibniz’ understanding of the relation between substance and body. I will show that Kant could have read some of the Arnauld correspondence and practically all of the Des Bosses correspondence, as well as a number of other related texts that are important for understanding Leibniz’ metaphysics, over a decade before writing the Critique of Pure Reason. Garber’s historical-textual argument for dismissing Kant’s account of Leibniz’ metaphysics is therefore seriously misleading.     

Jerome on Sinlessness: a Via Media between Augustine and Pelagius

This article will explore Jerome's understanding of sinlessness and will argue that he saw himself just as opposed to Augustine as to Pelagius. I begin by exposing Jerome's context in the Pelagian Controversy. I then expose his understanding of sinlessness. Next, I turn to his arguments in Ep. 133 and the first two books of his Dialogi contra Pelagianos. In book three of that text, we notice a change in his arguments which indicates that Jerome is no longer arguing only against Pelagius; he now disagrees with Augustine as well. I then examine a variety of issues besides sinlessness in the third book of the Dialogi that reveal that Jerome disagreed with Augustine on multiple topics, showing that his opposition to Augustine's position on sinlessness was not exceptional. Finally I turn to statements by Jerome that seem to indicate a positive appreciation for the Bishop of Hippo, but which on closer inspection are seen to contain latent criticisms.     

NEWTON AND WOLFF: THE LEIBNIZIAN REACTION TO THE PRINCIPIA, 1716–1763

Newton rested his theory of mechanics on distinct metaphysical and epistemological foundations. After Leibniz's death in 1716, the Principia ran into sharp philosophical opposition from Christian Wolff and his disciples, who sought to subvert Newton's foundations or replace them with Leibnizian ideas. In what follows, I chronicle some of the Wolffians' reactions to Newton's notion of absolute space, his dynamical laws of motion, and his general theory of gravitation. I also touch on arguments advanced by Newton's Continental followers, such as Leonhard Euler, who made novel attempts to defend his mechanical foundations against the pro‐Leibnizian attack. This examination grants us deeper insight into the fate of Newton's mechanics on the Continent during the early eighteenth century and, more specifically, sheds needed light on the conflicts and tensions that characterized the reception of Newton's philosophy of mechanics among the Leibnizians.     

Kant's Argument that Existence is not a Determination

In this paper, I examine Kant's famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non‐existent objects; necessarily, there are only existent objects. I argue further that Kant's target is not merely ontological arguments as such but the larger ‘ontotheist’ metaphysics they presuppose: the view that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that the ontotheist explanation of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I examine Kant's arguments in the Critique of Pure Reason against it.     

Spinoza’s Arguments for the Existence of God*

It is often thought that, although Spinoza develops a bold and distinctive conception of God (the unique substance, or Natura Naturans, in which all else inheres and which possesses infinitely many attributes, including extension), the arguments that he offers which purport to prove God’s existence contribute nothing new to natural theology. Rather, he is seen as just another participant in the seventeenth century revival of the ontological argument initiated by Descartes and taken up by Malebranche and Leibniz among others. That this is the case is both puzzling and unfortunate. It is puzzling because although Spinoza does offer an ontological proof for the existence of God, he also offers three other non‐ontological proofs. It is unfortunate because these other non‐ontological proofs are both more convincing and more interesting than his ontological proof. In this paper, I offer reconstructions and assessments of all of Spinoza’s arguments and argue that Spinoza’s metaphysical rationalism and his commitment to something like a Principle of Sufficient Reason are the driving force behind Spinoza’s non‐ontological arguments.     

Are liberal perfectionism and neutrality mutually exclusive?

In this paper, I question the view that liberal perfectionism and neutrality are mutually exclusive doctrines. I do so by criticizing two claims made by Jonathan Quong. First, I object to his claim that comprehensive anti-perfectionism is incoherent. Second, I criticize his claim that liberal perfectionism cannot avoid a paternalist stance. I argue that Quong’s substantive assumptions about personal autonomy undermine both of his arguments. I use the discussion of Quong to argue that the standard assumption in liberal theory about mutual exclusivity of liberal perfectionism and neutrality needs to be reconsidered, and I show why the argument about the convergence of perfectionism and neutrality makes conceptual sense.     

The complex tapestry of free will: striving will,indeterminism and volitional streams

The aim of this paper is to respond to recent discussion of, and objections to, the libertarian view of free will I have developed in many works over the past four decades. The issues discussed all have a bearing on the central question of how one might make sense of a traditional free will requiring indeterminism in the light of modern science. This task involves, among other things, avoiding all traditional libertarian appeals to unusual forms of agency or causation (uncaused causes, noumenal selves, non-event agent causes, etc.) that cannot be accounted for by ordinary modes of explanation familiar to the natural and human sciences. Doing this, I argue, requires piecing together a “complex tapestry” of ideas and arguments that involve rethinking many traditional assumptions about free will. The paper also argues that one cannot get to the heart of historical debates about free will without distinguishing different kinds of freedom, different senses of will, and different notions of control, among other distinctions. I especially focus here on different notions of freedom and control that are necessary to make sense of free will.

     

Leibniz on Conatus, Causation, and Freedom

Abstract: In this paper, I address the topic of free will in Leibniz with particular attention to Leibniz's concept of volition, and its analogue in his physics – his concept of force. I argue against recent commentators that Leibniz was a causal determinist, and thus a compatibilist, and I suggest that logical consistency required him to adopt compatibilism given some of the concepts at work in his physics. I conclude by pointing out that the pressures to adopt causal determinism in Leibniz's system are perhaps more severe than those facing the contemporary libertarian, pressures that stem from empirical considerations about the behavior of bodies in the physical world, and the “well‐founding” of those bodies in simple substances.     

The relationship between space and mutual interaction: Kant contra Newton and Leibniz

Kant claims that we cannot cognize the mutual interaction of substances without their being in space; he also claims that we cannot cognize a ‘spatial community’ among substances without their being in mutual interaction. I situate these theses in their historical context and consider Kant’s reasons for accepting them. I argue that they rest on commitments regarding the metaphysical grounding of, first, the possibility of mutual interaction among substances-as-appearances and, second, the actuality of specific distance-relations among such substances. By illuminating these commitments, I shed light on Kant’s metaphysics of space and its relation to Newton and Leibniz’s views.
