In his early discussion of the structure of matter and motion, Leibniz quite explicitly appeals to Aristotle's characterization of continuity, and seems to adopt something like it as his own. Commentators usually assume that Leibniz continues to understand the notion of continuity in this way for the rest of his life. This paper argues that although he does continue to use something like the Aristotelian conception well into the mature period of his thought, he articulates a second sense of continuity (...) in his later writings that proves to be a greater importance to the exposition of his mature metaphysics.

This chapter contains sections titled: The Imaginary Status of Shape: The “Diachronic” Argument The Dominant Synchronic Argument An Alternative Interpretation Shape and Idealism.

In this paper I challenge the common view that early in his career (1679-1695) Leibniz held that space and time are well-founded phenomena, entities on an ontological par with bodies and their properties. I argue that the evidence Leibniz ever held that space and time are well-founded phenomena is extremely weak and that there is a great deal of evidence for thinking that in the 1680s he held a position much like the one scholars rightly attribute to him in his (...) mature period, namely, that space and time are merely orders of existence and as such are purely abstract and occupy an ontological realm distinct from that of well-founded phenomena. In the course of arguing for this interpretation, I offer an account of the nature of Leibnizian phenomena which allows Leibniz to hold the view that space and time are phenomena, while at the same time thinking of them as abstract, ideal orders of existence.

In several of his writings from the 1680s, Leibniz presents an argument for the claim that there are no determinate or precise shapes in things, and states that shape contains something imaginary a...

Screening for unsuspected disease has both possible benefits and harms for those who participate. Historically the benefits of participation have been emphasized to maximize uptake reflecting a public health approach to policy; currently policy is moving towards an informed choice approach involving giving information about both benefits and harms of participation. However, no research has been conducted to evaluate the impact on health of an informed choice policy. Using psychological models, the first aim of this study was to describe an (...) explanatory framework for variation in screening uptake and to apply this framework to assess the impact of informed choices in screening. The second aim was to evaluate ethically that impact. Data from a general population survey of beliefs and attitudes towards participation in diabetes screening indicated that greater orientation to the present is associated with greater social deprivation and lower expectation of participation in screening. The results inform an explanatory framework of social patterning of screening in which greater orientation to the present focuses attention on the disadvantages of screening, which tend to be immediate, thereby reducing participation. This framework suggests that an informed choice policy, by increasing the salience of possible harms of screening, might reduce uptake of screening more in those who are more deprived and orientated to the present. This possibility gives rise to an apparent dilemma where an ethical decision must be made between greater choice and avoiding health inequality. Philosophical perspectives on choice and inequality are used to point to some of the complexities in assessing whether there really is such a dilemma and if so how it should be resolved. The paper concludes with a discussion of the ethics of paternalism. (shrink)

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a (...) kind of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

Understandably absorbed in technical details, discussion of the semantic paradoxes risks losing sight of broad methodological principles. This chapter sketches a general approach to the comparison of rival logics, and applies it to argue that revision of classical propositional logic has much higher costs than its proponents typically recognize.

In the 1960s, the strict opposition between the religious and the secular began to break down, blurring the distinction between political philosophy and political theology. This collapse contributed to the decline of modern liberalism, which supported a neutral, value-free space for capitalism. It also deeply unsettled political, religious, and philosophical realms, forced to confront the conceptual stakes of a return to religion. Gamely intervening in a contest that defies simple resolutions, Clayton Crockett conceives of the postmodern convergence of the (...) secular and the religious as a basis for emancipatory political thought. Engaging themes of sovereignty, democracy, potentiality, law, and event from a religious and political point of view, Crockett articulates a theological vision that responds to our contemporary world and its theo-political realities. Specifically, he claims we should think about God and the state in terms of potentiality rather than sovereign power. Deploying new concepts, such as Slavoj Žižek's idea of parallax and Catherine Malabou's notion of plasticity, his argument engages with debates over the nature and status of religion, ideology, and messianism. Tangling with the work of Derrida, Deleuze, Spinoza, Antonio Negri, Giorgio Agamben, Alain Badiou, John D. Caputo, and Catherine Keller, Crockett concludes with a reconsideration of democracy as a form of political thought and religious practice, underscoring its ties to modern liberal capitalism while also envisioning a more authentic democracy unconstrained by those ties.

Imagine a philosophy conference in Presocratic Greece. The hot question is: what are things made of? Followers of Thales say that everything is made of water, followers of Anaximenes that everything is made of air, and followers of Heraclitus that everything is made of fire. Nobody is quite clear what these claims mean, and some question whether the founders of the respective schools ever made them. But amongst the groupies there is a buzz about all the recent exciting progress. The (...) mockers and doubters make plenty of noise too. They point out that no resolution of the dispute between the schools is in sight. They diagnose Thales, Anaximenes and Heraclitus as suffering from a tendency to overgeneralize. We can intelligibly ask what bread is made of, or what houses are made of, but to ask what things in general are made of is senseless, some suggest, because the question is posed without any conception of how to verify an answer; language has gone on holiday. Paleo-pragmatists invite everyone to relax, forget their futile pseudo-inquiries and do something useful instead. (shrink)

This chapter aims to attempt no more than to make some informal and unsystematic remarks on the transformation of analytic philosophy. It deals with a few sketchy remarks on the historiography of recent analytic philosophy. Writing in 1981, David Lewis described “a reasonable goal for a philosopher” as bringing one’s opinions into stable equilibrium. A natural comparison is between Lewis’s Quinean or at least post‐Quinean methodology and the methodology of Peter Strawson, Quine’s leading opponent from the tradition of ordinary language (...) philosophy. Analytic epistemology provides a good case study of the philosophical application of Gricean pragmatics outside the philosophy of language. On Michael Dummett picture of the history of philosophy, Descartes had made epistemology first philosophy, the engine for the rest of philosophy, and then Frege had replaced epistemology by the philosophy of language as first philosophy. The chapter suggests that philosophy sometimes already uses an abductive methodology and ought to use it more in the future. (shrink)

The philosophical relevance of experimental psychology is hard to dispute. Much more controversial is the so‐called negative program's critique of armchair philosophical methodology, in particular the reliance on ‘intuitions’ about thought experiments. This chapter responds to that critique. It argues that, since the negative program has been forced to extend the category of intuition to ordinary judgments about real‐life cases, the critique is in immediate danger of generating into global scepticism, because all human judgments turn out to depend on intuitions. (...) Recently, some proponents of the negative program have tried to demarcate the target of their critique more narrowly. However, their attempts are still far too indiscriminate, and over‐generate scepticism. Nevertheless, once experimental philosophy has refined its own methodology, it may contribute to the refinement of the methodology of mainstream philosophy, by filtering out the effects of cognitive bias, although it offers no prospect of doing without judgments on real or imaginary cases.

In this chapter, we begin with a discussion of motivation itself, and use that discussion to sketch four possible theories of distinctively moral motivation: caricature versions of familiar instrumentalist, cognitivist, sentimentalist, and personalist theories about morally worthy motivation. To test these theories, we turn to a wealth of scientific, particularly neuroscientific, evidence. Our conclusions are that (1) although the scientific evidence does not at present mandate a unique philosophical conclusion, it does present formidable obstacles to a number of popular philosophical (...) approaches, and (2) theories of morally worthy motivation that best fit the current scientific picture are ones that owe much more to Hume or Aristotle than to Kant.

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

Kant limits cosmopolitan right to a universal right of hospitality, condemning European imperial practices towards indigenous peoples, while allowing a right to visit foreign countries for the purpose of offering to engage in commerce. I argue that attempts by contemporary theorists such as Jeremy Waldron to expand and update Kant’s juridical category of cosmopolitan right would blunt or erase Kant’s own anti-colonial doctrine. Waldron’s use of Kant’s category of cosmopolitan right to criticize contemporary identity politics relies on premises that upset (...) Kant’s balanced right to hospitality. An over-extensive right to visit can invoke “Kantian” principles that Kant himself could not have consistently held, without weakening his condemnation of European settlement. I construct an alternative spirit of cosmopolitan right more favorable to the contemporary claims of indigenous peoples. Kant’s analysis suggests there are circumstances when indigenous peoples may choose whether to engage in extensive cultural interaction, and reasonably refuse the risks of subjecting their claims to debate in democratic politics in a unitary public. Cosmopolitan right accorded respect to peoples; any “domestic” adaptation of cosmopolitan right should respect indigenous peoples as peoples, absent a serious public explanation by a democratic state for why it has now become appropriate to treat indigenous peoples merely as individual citizens.

This article adapts John Rawls’s writings, arguing that past injustice can change what we ought to publicly affirm as the standard of justice today. My approach differs from forward-looking approaches based on alleviating prospective disadvantage and backward-looking historical entitlement approaches. In different contexts, Rawls’s own concern for the ‘social bases of self-respect’ and equal citizenship may require public endorsement of different principles or specifications of the standard of justice. Rawls’s difference principle focuses on the least advantaged socioeconomic group. I argue (...) that a historicized difference principle considers the relative standing of racial, gender, and other historically stigmatized groups; provides their members assurance by weakening incentives to manipulate justice to another group’s advantage; and may result in policies resembling reparations, though justified by forward-looking considerations of self-respect and public assurance. I then examine how disrespectful justifications were historically used to forcibly include indigenous peoples as citizens. While Rawls thinks providing citizens one package of basic liberties signals respect, indigenous self-government could better support self-respect. I invoke Rawlsian international justice, which calls for mutual respect between peoples. Indigenous peoples’ status should reflect their past and persisting peoplehood, providing assurance by weakening incentives to unjustly transform international into domestic contexts. (shrink)

The topic of this paper is Aristotle’s ‘proof by refutation’ of the Principle of Non-Contradiction (Metaphysics Γ 4, 1006a11–1007a20). I consider a worry which has often been raised in connection with this proof. The worry is that, faced with an opponent who is prepared to tolerate contradictions, the argument is dialectically powerless: it is incapable of getting them to abandon their position. In reply, I argue that the proof needs to be seen in its proper context, that is, as part (...) of Aristotle’s response to an opponent who demands a demonstration of the principle. This allows us to clarify the purpose of the argument and answer the worry about its effectiveness. (shrink)

This paper discusses the nature and the status of inference to the best explanation. We outline the foundational role given IBE by its defenders and the arguments of critics who deny it any place at all ; argue that, on the two main conceptions of explanation, IBE cannot be a foundational inference rule ; sketch an account of IBE that makes it contextual and dependent on substantive empirical assumptions, much as simplicity seems to be ; show how that account avoids (...) the critics ' complaints and leaves IBE an important role ; and sketch how our account can clarify debates over IBE in arguments for scientific realism.

This volume offers readers a unique and comprehensive overview of theoretical perspectives on "the sublime," the singular aesthetic response elicited by phenomena that move viewers by transcending and overwhelming them. The book consists of an editor's introduction and fifteen chapters written from a variety of disciplinary perspectives. Part One examines philosophical approaches advanced historically to account for the phenomenon, beginning with Longinus, moving through eighteenth and nineteenth century writers in Britain, France, and Germany, and concluding with developments in contemporary continental (...) philosophy. Part Two explores the sublime with respect to particular disciplines and areas of study, including Dutch literature, early modern America, the environment, religion, British Romanticism, the fine arts, and architecture. Each chapter is both accessible for nonspecialists and offers an original contribution to its respective field of inquiry. (shrink)

Can advances in neuroscience be harnessed to enhance human moral capacities? And if so, should they? De Grazia explores these questions in ‘Moral Enhancement, Freedom, and What We Value in Moral Behaviour’.1 Here, I offer a neuroscientist's perspective on the state of the art of moral bioenhancement, and highlight some of the practical challenges facing the development of moral bioenhancement technologies.The science of moral bioenhancement is in its infancy. Laboratory studies of human morality usually employ highly simplified models aimed at (...) measuring just one facet of a cognitive process that is relevant for morality. These studies have certainly deepened our understanding of the nature of moral behaviour, but it is important to avoid overstating the conclusions of any single study. De Grazia cites several purported examples of ‘non-traditional means of moral enhancement’, including one of my own studies. According to De Grazia, we showed that ‘selective serotonin reuptake inhibitors as a means to being less inclined to assault people’. In fact, our findings are a bit more subtle and nuanced than implied in the target article, as is often the case in neuroscientific studies of complex human behaviour. In our study, we tested the effects of the selective serotonin reuptake …. (shrink)

To desire something is a condition familiar to everyone. It is uncontroversial that desiring has something to do with motivation, something to do with pleasure, and something to do with reward. Call these "the three faces of desire." The standard philosophical theory at present holds that the motivational face of desire presents its unique essence--to desire a state of affairs is to be disposed to act so as to bring it about. A familiar but less standard account holds the hedonic (...) face of desire to reveal to true nature of desire. In this view, to desire something is to tend to pleasure if it seems that the desired state of affairs has been achieved, or displeasure if it seems otherwise, thus tying desire to feelings instead of actions. In Three Faces of Desire, Schroeder goes beyond actions and feelings to advance a novel and controversial theory of desire that puts the focus on desire's neglected face, reward. Informed by contemporary science as much as by the philosophical tradition, Three Faces of Desire discusses recent scientific discoveries that tell us much about the way that actions and feelings are produced in the brain. In particular, recent experiments reveal that a distinctive system is responsible for promoting action, on the one hand, and causing feelings of pleasure and displeasure, on the other. This system, the brain's reward system, is the causal origin of both action and feeling, and is the key to understanding the nature of desire. (shrink)

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

Rousseau’s account of the “legislator” or “lawgiver” is commonly regarded as one of the most far-fetched, ominous, and baffling parts of his teaching in the Social Contract. In brief, Rousseau’s lawgiver seems to be a proto-totalitarian figure whose self-appointed mission is to found a political community by “denaturing” people at a single stroke and who may be a mere figment of Rousseau’s overheated imagination. Accordingly, this part of the Social Contract threatens to make a mockery of Rousseau’s claim to be (...) “taking men as they are and laws they can be,” as well as his claim that the combination of “ freedom and equality” is “the greatest good” in the civil state. Following and extending Rousseau’s own method of teaching by examples, however, this essay argues that Benjamin Franklin’s influence over the American republic—especially through his posthumous Autobiography—offers a prosaic example of the apparently fantastical phenomenon sketched by Rousseau. In fact, I argue that Franklin’s case corresponds more fully to Rousseau’s description than do any of Rousseau’s own examples (such as Moses, Lycurgus, and Numa) and that Franklin showed in practice what Rousseau suggested in theory: that a lawgiver can succeed without relying on coercion and without undercutting the equality that underlies a just society. Franklin’s denaturing influence, I suggest, has been crucial for the durability of republicanism in the United States, given the country’s size and diversity. (shrink)

Catherine Malabou, Antonio Negri, John D. Caputo, Bruno Bosteels, Mark C. Taylor, and Slavoj Zizek join seven others--including William Desmond, Katrin Pahl, Adrian Johnston, Edith Wyschogrod, and Thomas A. Lewis--to apply Hegel's thought to twenty-first-century philosophy, politics, and religion. Doing away with claims that the evolution of thought and history is at an end, these thinkers safeguard Hegel's innovations against irrelevance and, importantly, reset the distinction of secular and sacred. These original contributions focus on Hegelian analysis and the transformative value (...) of the philosopher's thought in relation to our current "turn to religion." Malabou develops Hegel's motif of confession in relation to forgiveness; Negri writes of Hegel's philosophy of right; Caputo reaffirms the radical theology made possible by Hegel; and Bosteels critiques fashionable readings of the philosopher and argues against the reducibility of his dialectic. Taylor reclaims Hegel's absolute as a process of infinite restlessness, and Zizek revisits the religious implications of Hegel's concept of letting go. Mirroring the philosopher's own trajectory, these essays progress dialectically through politics, theology, art, literature, philosophy, and science, traversing cutting-edge theoretical discourse and illuminating the ways in which Hegel inhabits them.

What we call “the evidential argument from evil” is not one argument but a family of them, originating (perhaps) in the 1979 formulation of William Rowe. Wykstra’s early versions of skeptical theism emerged in response to Rowe’s evidential arguments. But what sufficed as a response to Rowe may not suffice against later more sophisticated versions of the problem of evil—in particular, those along the lines pioneered by Paul Draper. Our chief aim here is to make an earlier version of skeptical (...) theism more responsive to the type abductive atheology pioneered by Draper. In particular, we suggest a moderate form of skeptical theism may be able to resist Draper’s abductive atheology. (shrink)

Although many information system ontologies (ISOs) claim to be parsimonious, the notion of parsimony seems to influence the debate on ISOs only at the level of vague and uncritical assumption. To challenge this trend, the paper aims to clarify what it means for ISOs to be parsimonious. Specifically, section 2 shows that parsimony in computer science generally concerns software design and, together with elegance, is one of the two aspects of the broader notion of simplicity. Section 3 transforms the main (...) claims of parsimony in software design into claims about the content of ISOs, the combination of which is hereafter called “parsimony of content”—where “content” refers only to the content of ISOs. Sections 4-7 discuss the application of this parsimony to the design of ISOs, and outline different kinds (and combinations) of parsimony of content. Finally, section 8 considers whether parsimony of content could provide some criteria both for selecting and/or classifying the contents of ISOs and for choosing between different and equally consistent ISOs.

This work presents a historically informed, systematic exposition of the Christology of the first seven Ecumenical Councils of undivided Christendom, from the First Council of Nicaea in 325 AD to the Second Council of Nicaea in 787 AD. Assuming the truth of Conciliar Christology for the sake of argument, Timothy Pawl considers whether there are good philosophical arguments that show a contradiction or incoherence in that doctrine. He presents the definitions of important terms in the debate and a helpful (...) metaphysics for understanding the incarnation. -/- In Defense of Conciliar Christology discusses three types of philosophical objections to Conciliar Christology. Firstly, it highlights the fundamental philosophical problem facing Christology: how can one thing be both God and man, when anything deserving to be called "God" must have certain attributes, and yet it seems that nothing that can aptly be called "man" can have those same attributes? It then considers the argument that if the Second Person of the Holy Trinity were immutable or atemporal, as Conciliar Christology requires, then that Person could not become anything, and thus could not become man. Finally, Pawl addresses the objection that if there is a single Christ then there is a single nature or will in Christ. However, if that conditional is true, then Conciliar Christology is false, since it affirms the antecedent of the conditional to be true, but denies the truth of the consequent. Pawl defends Conciliar Christology against these charges, arguing that all three philosophical objections fail to show Conciliar Christology inconsistent or incoherent. (shrink)

As topics in the philosophy of emotion, pleasure and displeasure get less than their fair share of attention. On the one hand, there is the fact that pleasure and displeasure are given no role at all in many theories of the emotions, and secondary roles in many others.1 On the other, there is the centrality of pleasure and displeasure to being emotional. A woman who tears up because of a blustery wind, while an ill-advised burrito weighs heavily upon her digestive (...) tract, feels an impressive number of the sensations felt by someone who is gut-wrenchingly sad. Yet, unless she feels bad, the way she feels is only a pale echo of the feeling of sadness. If she feels good in spite of the burrito and the wind, then she does not feel at all the way she would if she were sad. Likewise, a man falling asleep can hardly fail to feel his muscles relax, his heart rate fall, and so on, but unless he feels good his state is only a shadow of feeling content. This paper will begin with a sketch of the nature of pleasure and displeasure, and the relation between them and the feelings that are characteristic of emotions. It will then argue that the capacity to feel pleased and displeased is, quite literally, a sense modality: one allowing us to perceive net change in the satisfaction of our intrinsic desires. As with any sense modality, the capacity to feel pleased and displeased displays substantial modularity. The paper concludes by considering the ways in which the modularity of pleasure and displeasure contributes to effects that might reasonably be called “the modularity of the emotions.”. (shrink)
