Published in 1903, this book was the first comprehensive treatise on the logical foundations of mathematics written in English. It sets forth, as far as possible without mathematical and logical symbolism, the grounds in favour of the view that mathematics and logic are identical. It proposes simply that what is commonly called mathematics are merely later deductions from logical premises. It provided the thesis for which _Principia Mathematica_ provided the detailed proof, and introduced the work of Frege to a wider (...) audience. In addition to the new introduction by John Slater, this edition contains Russell's introduction to the 1937 edition in which he defends his position against his formalist and intuitionist critics.

The Epistemic Objection says that certain theories of time imply that it is impossible to know which time is absolutely present. Standard presentations of the Epistemic Objection are elliptical—and some of the most natural premises one might fill in to complete the argument end up leading to radical skepticism. But there is a way of filling in the details which avoids this problem, using epistemic safety. The new version has two interesting upshots. First, while Ross Cameron alleges that the Epistemic (...) Objection applies to presentism as much as to theories like the growing block, the safety version does not overgeneralize this way. Second, the Epistemic Objection does generalize in a different, overlooked way. The safety objection is a serious problem for a widely held combination of views: “propositional temporalism” together with “metaphysical eternalism”. (shrink)

How should a group with different opinions (but the same values) make decisions? In a Bayesian setting, the natural question is how to aggregate credences: how to use a single credence function to naturally represent a collection of different credence functions. An extension of the standard Dutch-book arguments that apply to individual decision-makers recommends that group credences should be updated by conditionalization. This imposes a constraint on what aggregation rules can be like. Taking conditionalization as a basic constraint, we gather (...) lessons from the established work on credence aggregation, and extend this work with two new impossibility results. We then explore contrasting features of two kinds of rules that satisfy the constraints we articulate: one kind uses fixed prior credences, and the other uses geometric averaging, as opposed to arithmetic averaging. We also prove a new characterisation result for geometric averaging. Finally we consider applications to neighboring philosophical issues, including the epistemology of disagreement. (shrink)

David Lewis holds that a single possible world can provide more than one way things could be. But what are possible worlds good for if they come apart from ways things could be? We can make sense of this if we go in for a metaphysical understanding of what the world is. The world does not include everything that is the case—only the genuine facts. Understood this way, Lewis's “cheap haecceitism” amounts to a kind of metaphysical anti-haecceitism: it says there (...) aren't any genuine facts about individuals over and above their qualitative roles. (shrink)

We prove a representation theorem for preference relations over countably infinite lotteries that satisfy a generalized form of the Independence axiom, without assuming Continuity. The representing space consists of lexicographically ordered transfinite sequences of bounded real numbers. This result is generalized to preference orders on abstract superconvex spaces.

We explore the view that Frege's puzzle is a source of straightforward counterexamples to Leibniz's law. Taking this seriously requires us to revise the classical logic of quantifiers and identity; we work out the options, in the context of higher-order logic. The logics we arrive at provide the resources for a straightforward semantics of attitude reports that is consistent with the Millian thesis that the meaning of a name is just the thing it stands for. We provide models to show (...) that some of these logics are non-degenerate. (shrink)

I examine three ‘anti-object’ metaphysical views: nihilism, generalism, and anti-quantificationalism. After setting aside nihilism, I argue that generalists should be anti-quantificationalists. Along the way, I attempt to articulate what a ‘metaphysically perspicuous’ language might even be.

“There are no gaps in logical space,” David Lewis writes, giving voice to sentiment shared by many philosophers. But different natural ways of trying to make this sentiment precise turn out to conflict with one another. One is a *pattern* idea: “Any pattern of instantiation is metaphysically possible.” Another is a *cut and paste* idea: “For any objects in any worlds, there exists a world that contains any number of duplicates of all of those objects.” We use resources from model (...) theory to show the inconsistency of certain packages of combinatorial principles and the consistency of others. (shrink)

Famous results by David Lewis show that plausible-sounding constraints on the probabilities of conditionals or evaluative claims lead to unacceptable results, by standard probabilistic reasoning. Existing presentations of these results rely on stronger assumptions than they really need. When we strip these arguments down to a minimal core, we can see both how certain replies miss the mark, and also how to devise parallel arguments for other domains, including epistemic “might,” probability claims, claims about comparative value, and so on. A (...) popular reply to Lewis's results is to claim that conditional claims, or claims about subjective value, lack truth conditions. For this strategy to have a chance of success, it needs to give up basic structural principles about how epistemic states can be updated—in a way that is strikingly parallel to the commitments of the project of dynamic semantics.

Where Nature thus determines us, we have an original non-rational commitment which sets the bounds within which, or the stage upon which, reason can effectively operate.

Could space consist entirely of extended regions, without any regions shaped like points, lines, or surfaces? Peter Forrest and Frank Arntzenius have independently raised a paradox of size for space like this, drawing on a construction of Cantor’s. I present a new version of this argument and explore possible lines of response.

The immediate aim of this paper is to articulate the essential features of an alternative compatibilist position, one that is responsive to sources of resistance to the compatibilist program based on considerations of fate and luck. The approach taken relies on distinguishing carefully between issues of skepticism and pessimism as they arise in this context. A compatibilism that is properly responsive to concerns about fate and luck is committed to what I describe as free will pessimism, which is to be (...) distinguished from free will skepticism. Free will skepticism is the view that our vulnerability to conditions of fate and luck serve to discredit our view of ourselves as free and responsible agents. Free will pessimism rejects free will scepticism, since the basis of its pessimism rests with the assumption that we are free and responsible agents who are, nevertheless, subject to fate and luck in this aspect of our lives. According to free will pessimism, all the major parties and positions in the free will debate, including that of skepticism, are modes of evasion and distortion regarding our human predicament in respect of agency and moral life.

The counterpart theorist has a problem: there is no obvious way to understand talk about actuality in terms of counterparts. Fara and Williamson have charged that this obstacle cannot be overcome. Here I defend the counterpart theorist by offering systematic interpretations of a quantified modal language that includes an actuality operator. Centrally, I disentangle the counterpart relation from a related notion, a ‘representation relation’. The relation of possible things to the actual things they represent is variable, and an adequate account (...) of modal language must keep track of the way it is systematically shifted by modal operators. I apply my account to resolve several puzzles about counterparts and actuality. In technical appendices, I prove some important logical results about this ‘representational’ counterpart system and its relationship to other modal systems. (shrink)

“Pragmatic encroachers” about knowledge generally advocate two ideas: (1) you can rationally act on what you know; (2) knowledge is harder to achieve when more is at stake. Charity Anderson and John Hawthorne have recently argued that these two ideas may not fit together so well. I extend their argument by working out what “high stakes” would have to mean for the two ideas to line up, using decision theory.

Recent work in contemporary compatibilist theory displays considerable sophistication and subtlety when compared with the earlier theories of classical compatibilism. Two distinct lines of thought have proved especially influential and illuminating. The first developed around the general hypothesis that moral sentiments or reactive attitudes are fundamental for understanding the nature and conditions of moral responsibility. The other important development is found in recent compatibilist accounts of rational self-control or reason responsiveness. Strictly speaking, these two lines of thought have developed independent (...) of each other. However, in the past decade or so they have been fused together in several prominent statements of compatibilist theory. I will refer to theories that combine these two elements in this way as RS theories. RS theories face a number of familiar difficulties that relate to each of their two components. Beyond this, they also face a distinct set of problems concerning how these two main components relate or should be integrated. My concerns in this paper focus primarily on this set of problems. According to one version of RS compatibilism, the role of moral sentiments is limited to explaining what is required for holding an agent responsible. In contrast with this, the role of reason responsiveness is to explain what moral capacities are required for an agent to be responsible, one who is a legitimate or fair target of our moral sentiments. More specifically, according to this view, moral sense is not required for rational selfcontrol or reason responsiveness. There is, therefore, no requirement that the responsible agent has some capacity to feel moral sentiment. Contrary to this view, I argue that a responsible agent must be capable of holding herself and others responsible. Failing this, an agent’s powers of rational self-control will be both limited and impaired. In so far as holding responsible requires moral sense, it follows that being responsible also requires moral sense. (shrink)

Suppose that all non-qualitative facts are grounded in qualitative facts. I argue that this view naturally comes with a picture in which trans-world identity is indeterminate. But this in turn leads to either pervasive indeterminacy in the non-qualitative, or else contingency in what facts about modality and possible worlds are determinate.

Some hold that the lesson of Russell’s paradox and its relatives is that mathematical reality does not form a ‘definite totality’ but rather is ‘indefinitely extensible’. There can always be more sets than there ever are. I argue that certain contact puzzles are analogous to Russell’s paradox this way: they similarly motivate a vision of physical reality as iteratively generated. In this picture, the divisions of the continuum into smaller parts are ‘potential’ rather than ‘actual’. Besides the intrinsic interest of (...) this metaphysical picture, it has important consequences for the debate over absolute generality. It is often thought that ‘indefinite extensibility’ arguments at best make trouble for mathematical platonists; but the contact arguments show that nominalists face the same kind of difficulty, if they recognize even the metaphysical possibility of the picture I sketch. (shrink)

Some philosophers respond to Leibniz’s “shift” argument against absolute space by appealing to antihaecceitism about possible worlds, using David Lewis’s counterpart theory. But separated from Lewis’s distinctive system, it is difficult to understand what this doctrine amounts to or how it bears on the Leibnizian argument. In fact, the best way of making sense of the relevant kind of antihaecceitism concedes the main point of the Leibnizian argument, pressing us to consider alternative spatiotemporal metaphysics.

.... The strategy I have defended involves drawing a distinction between those who can and cannot legitimately hold an agent responsible in circumstances when the agent is being covertly controlled (e.g. through implantation processes). What is intuitively unacceptable, I maintain, is that an agent should be held responsible or subject to reactive attitudes that come from another agent who is covertly controlling or manipulating him. This places some limits on who is entitled to take up the participant stance in relation (...) to agents who are rational self-controllers but nevertheless subject to covert control.26 In this way, what is compromised by conditions of covert control is not the responsibility of the agent as such. It is, rather, the participant stance of those other agents who covertly control him. Clearly it is possible to establish these specific limits on who can hold these agents responsible without denying that the agents themselves remain free and responsible. When we take this approach we will find that we are no longer faced with an unattractive choice between simply “biting the bullet” or having to “spit it out”. All we need to do is chew carefully, until there is nothing left that we find too hard to swallow. (shrink)

The discussion in this paper begins with some observations regarding a number of structural similarities between art and morality as it involves human agency. On the basis of these observations we may ask whether or not incompatibilist worries about free will are relevant to both art and morality. One approach is to claim that libertarian free will is essential to our evaluations of merit and desert in both spheres. An alternative approach, is to claim that free will is required only (...) in the sphere of morality—and that to this extent the art/morality analogy breaks down. I argue that both these incompatibilist approaches encounter significant problems and difficulties—and that incompatibilist have paid insufficient attention to these issues. However, although the analogy between art and morality may be welcomed by compatibilists, it does not pave the way for an easy or facile optimism on this subject. On the contrary, while the art/morality analogy may lend support to compatibilism it also serves to show that some worries of incompatibilism relating to the role of luck in human life cannot be easily set aside, which denies compatibilism any basis for complacent optimism on this subject.

The central thesis of this paper is that the scope and structure of Hume's Treatise of Human Nature is modelled, or planned, after that of Hobbes's The Elements of Law and that in this respect there exists an important and unique relationship between these works. This relationship is of some importance for at least two reasons. First, it is indicative of the fundamental similarity between Hobbes's and Hume's project of the study of man. Second, and what is more important, by (...) recognizing this relationship between Hume's and Hobbes's works we can come to appreciate the unity of the project of the Treatise itself. My discussion will proceed in three stages. In section I present the evidence for my central thesis. In the second section I shall consider why Hume does not, as one might expect, acknowledge this important debt to Hobbes in the Introduction to the Treatise or in the Abstract. Finally, in the third section I shall note a few points of some importance to the understanding of Hume's philosophy which this relationship between Hobbes's and Hume's work touches upon. (shrink)

The philosophy of Samuel Clarke is of central importance to Hume’s Treatise. Hume’s overall attitude to Clarke’s philosophy may be characterized as one of systematic scepticism. The general significance of this is that it sheds considerable light on Hume’s fundamental “atheistic” or anti-Christian intentions in the Treatise. These are all claims that I have argued for elsewhere.’ In this paper I am concerned to focus on a narrower aspect of this relationship between the philosophies of Clarke and Hume. Specifically, I (...) will consider Hume’s views on the subjects of materialism and necessity in relation to Clarke’s enormously influential debate with Anthony Collins on these topics. I begin by describing the nature and context of this controversy; I then examine how Hume‘s positions on questions of materialism and necessity stand in relation to the positions and arguments taken up by Clarke and Collins; and finally I explain the deeper significance of these specific issues for Hume’s wider “atheistic” or anti-Christian objectives in the Treatise. Hume’s views on the closely related subjects of materialism and necessity, I maintain, constitute core elements of his “atheistic” project in the Treatise, and they manifest his basic antipathy to the theistic metaphysics of the Christian religion in general,and to the Newtonian cosmology of Clarke in particular.

THE SUBJECT MATTER of this essay is Locke's well-known discussion of consent in sections 116-122 of the Second Treatise of Government.' I will not be concerned to discuss the place of consent in Locke's political philosophy 2 My concerns are somewhat narrower than this. I will simply be concerned to show that in important respects several recent discussions of Locke's political philosophy have misrepresented Locke's views on the subject of express and tacit consent. At theheart of these misinterpretations lie misunderstandings (...) about the way in which landownership and the inheritance of land are related to express and tacit consent. I will show that these misinterpretations of Locke's views are, to a certain extent, indicative of internal strains that can bediscovered in Locke's arguments. My discussion will fall into four sections. In the first I will try toclarify Locke's views on the nature of express consent. I will show that Locke's views on this matter, when examined in their historical context, are not as obscure as some critics have suggested. In the second section I will examine Locke's views on the nature of tacit consent. I will be especially concerned to examine the relationship between landownership and express and tacit consent. In the third section I will look at Locke's views on the inheritance of land and how it relates to express and tacit consent. I will show that his views on this matter are not entirely consistent. In one passage Locke suggests that inheritance of land requires only tacit consent whereas, in another passage, he suggests that inheritance of land requires full membership of society and express consent. In the fourth and final section I will summarize the salient features of my interpretation of Locke's views on the subject of express and tacit consent. I will also briefly note interpretations of Locke's views that have been rejected in the course of this essay. ____ Reprinted in J.R.Milton, ed., Locke's Moral, Political and Legal Philosophy (Ashgate, 1999), 465-482. -/- .

We analyze the logical form of the domain knowledge that grounds analogical inferences and generalizations from a single instance. The form of the assumptions which justify analogies is given schematically as the "determination rule", so called because it expresses the relation of one set of variables determining the values of another set. The determination relation is a logical generalization of the different types of dependency relations defined in database theory. Specifically, we define determination as a relation between schemata of first (...) order logic that have two kinds of free variables: (1) object variables and (2) what we call "polar" variables, which hold the place of truth values. Determination rules facilitate sound rule inference and valid conclusions projected by analogy from single instances, without implying what the conclusion should be prior to an inspection of the instance. They also provide a way to specify what information is sufficiently relevant to decide a question, prior to knowledge of the answer to the question. (shrink)

Smith's views on moral luck have attracted little attention in the relevant contemporary literature on this subject.* More surprising, perhaps, the material in the secondary literature directly concerned with Smith's moral philosophy is rather thin on this aspect of his thought. In this paper my particular concern is to provide an interpretation and critical assessment of Smith on moral luck. I begin with a description of the basic features of Smith's position; then I criticize two particularly important claims that are (...) fundamental to his position; and I conclude with an examination of the significance of Smith's discussion in relation to the contemporary debate. * There is some change in this situation since this paper was originally published.

This article examines the free will problem as it arises within Thomas Hobbes' naturalistic science of morals in early modern Europe. It explains that during this period, the problem of moral and legal responsibility became acute as mechanical philosophy was extended to human psychology and as a result human choices were explained in terms of desires and preferences rather than being represented as acts of an autonomous faculty. It describes how Hobbes changed the face of moral philosophy, through his Leviathan, (...) in ways that still structure and resonate within the contemporary debate. (shrink)

In her influential and challenging paper “Skepticism about Practical Reason” Christine Korsgaard sets out to refute an important strand of Humean scepticism as it concerns a Kantian understanding of practical reason.1 Korsgaard distinguishes two components of scepticism about practical reason. The first, which she refers to as content scepticism, argues that reason cannot of itself provide any “substantive guidance to choice and action” (SPR, 311). In its classical formulation, as stated by Hume, it is argued that reason cannot determine our (...) ends. Our ends are determined by our desires and reason is limited to the role of identifying the relevant means to these ends. The second component, which Korsgaard calls motivational scepticism, suggests doubt about the scope of reason as a motive. The claim here, as Korsgaard interprets Hume’s view on this matter, is that “all reasoning that has motivational influence must start from a passion, that being the only possible source of motivation” (SPR, 314).2 Korsgaard’s fundamental objective in “Skepticism about Practical Reason” is to show that motivational scepticism must always be based on content scepticism. In other words, according to Korsgaard, motivational scepticism has no independent force. In this paper I argue that Korsgaard’s attempt to discredit motivational scepticism is unsuccessful.

: In this paper I argue that Hume's famous discussion of probability and induction, as originally presented in the Treatise, is significantly motivated by irreligious objectives. A particular target of Hume's arguments is Joseph Butler's Analogy of Religion. In the Analogy Butler intends to persuade his readers of both the credibility and practical importance of the doctrine of a future state of rewards and punishments. The argument that he advances relies on probable reasoning and proceeds on the assumption that our (...) past experience in this life serves as a reliable and effective guide for our expectations concerning a future state. In the relevant sections of the Treatise Hume aims to discredit this religious argument and the practical objectives associated with it. (shrink)

IN Necessity, Cause and Blame (London: Duckworth, 1980) Richard Sorabji attempts to develop a notion of moral responsibility which does not get caught on either horn of a well known dilemma. One horn is the argument that if an action was caused then it must have been necessary and therefore could not be one for which the agent is responsible. The other horn is the argument that if the action was not caused then it is inexplicable and random and therefore (...) not something which the agent can be responsible for. Sorabji denies that what is caused is always necessitated. Causes are primarily explanatory rather than necessitating. This established, Sorabji hopes to show that action open to moral scrutiny may be caused without being necessitated and the dilemma collapses. I will argue that this strategy runs into serious difficulties. (shrink)

In this paper I pursue two closely related objectives. First, I articulate and describe the nature and character of Hume's theory of punishment. Second, in light of this account, I offer an assessment of the contem- porary interest and value of Hume's theory. Throughout my discus- sion I emphasize the relevance and importance of Hume's views on moral responsibility to his account of punishment.1 More specifically, I argue that Hume seeks to develop an account of punishment on the foundation of (...) a naturalistic theory of responsibility - that is, a theory which draws our attention to the role of moral sentiment in this sphere.2 Although this naturalistic aspect of Hume's theory of punishment has been largely overlooked by commentators, I maintain that it is, nevertheless, precisely this aspect of Hume's theory that is especially interesting from a contemporary pers.

I present and discuss three previously unpublished manuscripts written by Bertrand Russell in 1903, not included with similar manuscripts in Volume 4 of his Collected Papers. One is a one-page list of basic principles for his “functional theory” of May 1903, in which Russell partly anticipated the later Lambda Calculus. The next, catalogued under the title “Proof That No Function Takes All Values”, largely explores the status of Cantor’s proof that there is no greatest cardinal number in the variation of (...) the functional theory holding that only some but not all complexes can be analyzed into function and argument. The final manuscript, “Meaning and Denotation”, examines how his pre-1905 dis­tinction between meaning and denotation is to be understood with respect to functions and their arguments. In them, Russell seems to endorse an extensional view of functions not endorsed in other works prior to the 1920s. All three manuscripts illustrate the close connection between his work on the logical paradoxes and his work on the theory of meaning. (shrink)

Forgiveness theorists focus a good deal on explicating the content of what they take to be a shared folk concept of forgiveness. Our empirical research, however, suggests that there is a range of concepts of forgiveness present in the population, and therefore that we should be folk conceptual pluralists about forgiveness. We suggest two possible responses on the part of forgiveness theorists: (1) to deny folk conceptual pluralism by arguing that forgiveness is a functional concept and (2) to accept folk (...) conceptual pluralism and focus on a revisionary conceptual ethics project.

The existence of mereological sums can be derived from an abstraction principle in a way analogous to numbers. I draw lessons for the thesis that “composition is innocent” from neo-Fregeanism in the philosophy of mathematics.

When I was eleven, my form teacher, Mr Howard, showed some of my class how to punch. We were waiting for the rest of the class to finish changing after gym, and he took a stance that I would now call shizentai yoi and snapped his right fist forward into a head-level straight punch, pulling his left back to his side at the same time. Then he punched with his left, pulling back on his right. We all lined up in (...) our ties and sensible shoes (this was England) and copied him—left, right, left, right—and afterwards he told us that if we practised in the air with sufficient devotion for three years, then we would be able to use our punches to kill a bull with one blow. I worshipped Mr Howard (though I would sooner have died than told him that) and so, as a skinny, eleven-year-old girl, I came to believe that if I practised, I would be able to kill a bull with one blow by the time I was fourteen. This essay is about epistemic viciousness in the martial arts, and this story is illustrates just that. Though the word ‘viciousness’ normally suggests deliberate cruelty and violence, I will be using it here with the more old-fashioned meaning, possessing of vices. Vices (such as avarice, alcoholism and nail-biting) are common, and most of us struggle with a few, but ‘epistemic’ means ‘having to do with knowledge and the justification of belief’ and so epistemic viciousness is the possession of vices that make one bad at acquiring true beliefs, or give one a tendency to form false ones. My eleven-year-old self possessed the epistemic vice of gullibility and hence showed a streak of epistemic viciousness, which led to the formation of a false belief. Other kinds of epistemic vice can lead to us failing to form true beliefs when we ought to.

In the third and final part of his A Theory of Determinism (TD) Ted Honderich addresses the fundamental question concerning “the consequences of determinism.” The critical question he aims to answer is what follows if determinism is true? This question is, of course, intimately bound up with the problem of free will and, in particular, with the question of whether or not the truth of determinism is compatible or incompatible with the sort of freedom required for moral responsibility. It is (...) Honderich’s aim to provide a solution to “the problem of the consequences of determinism” and a key element of this is his articulation and defence of an alternative response to the implications of determinism that collapses the familiar Compatibilist/Incompatibilist dichotomy. Honderich offers us a third way – the response of “Affirmation” (HFY 125-6). Although his account of Affirmation has application and relevance to issues and features beyond freedom and responsibility, my primary concern in this essay will be to examine Honderich’s theory of “Affirmation” as it concerns the free will problem.

David Hume’s views on the subject of free will are among the most influential contributions to this long-disputed topic. Throughout the twentieth century, and into this century, Hume has been widely regarded as having presented the classic defense of the compatibilist position, the view that freedom and responsibility are consistent with determinism. Most of Hume’s core arguments on this issue are found in the sections entitled “Of liberty and necessity,” first presented in Book 2 of A Treatise of Human Nature (...) (1739) and then in his An Enquiry concerning Human Understanding (1748). Although the general position in both these works is much the same, there are some significant points of difference relating to the way in which the core position is presented and also in the specific range of arguments covered. The focus of my concerns in this essay will not, however, lie with the relationship between the Treatise and the first Enquiry versions of “Of liberty and necessity.” My discussion will center on the contrast between two alternative interpretations of Hume’s views on this subject, with particular reference to the version presented in the Treatise. It will be my particular concern to explain and defend the naturalistic as against the classical compatibilist account and to explain the general significance of the naturalistic account for the contemporary debate.

Bernard Williams is widely recognized as belonging among the greatest and most influential moral philosophers of the twentieth-century – and arguably the greatest British moral philosopher of the late twentieth-century. His various contributions over a period of nearly half a century changed the course of the subject and challenged many of its deepest assumptions and prejudices. There are, nevertheless, a number of respects in which the interpretation of his work is neither easy nor straightforward. One reason for this is that (...) both his views and his methods evolved and shifted in significant ways, especially around the time that he wrote and published Ethics and the Limits of Philosophy (i.e. the early 1980s). One way of gauging and assessing these changes in Williams’ views and outlook is to consider his relationship and attitude to other philosophers during this period. Of particular interest is his changing attitude to the moral philosophy of David Hume. This relationship is of considerable importance, not only because it serves as a useful tool for the interpretation of Williams’ views but also because it provides us with some critical insight into the respective strengths and weaknesses of both Hume’s and Williams’ contributions. -/- .

Throughout this paper my objective will be to establish and clarify Hume's original intentions in his discussion of causation in Book I of the Treatise. I will show that Hume's views on ontology, presented in Part IV of that book, shed light on his views on causation as presented in Part III. Further, I will argue that Hume's views on ontology account for the original motivation behind his two definitions of 2 cause. This relationship between Hume's ontology and his account (...) of causation explains something which has baffled Hume scholars for some time,- namely, why does Hume's discussion of causation in I, iii, 14 have such a paradoxical air about it? I will show that Hume's views on causation have a paradoxical air about them because they rest on an ontology of "double existence" - an ontology which Hume describes as the monstrous offspring of two principles, which are contrary to each other, which are both at once embrac'd by the mind, and which are unable mutually to destroy each other (T 215) My interpretation will centre on the following two claims: (i) When Hume wrote Section 14, Of the idea of necessary connexion, he was primarily concerned to attack the view that the origin of our idea of necessity was to be discovered in the operations of matter or bodies. Of the suggested sources from which our idea of necessity could be thought to originate this is the source which, initially, interested Hume the most. It is, therefore, of great importance that we interpret Hume's remarks in light of this fact. (ii) Hume offers the first definition of cause as an account of causation as it exists in the material world independent of our thought and reasoning.He offers the second definition as an account of causation as we find it in our perceptions. It will also be argued, in this context, that necessity constitutes "an essential part" of both of Hume's two definitions of cause. (shrink)

People with the kind of preferences that give rise to the St. Petersburg paradox are problematic---but not because there is anything wrong with infinite utilities. Rather, such people cannot assign the St. Petersburg gamble any value that any kind of outcome could possibly have. Their preferences also violate an infinitary generalization of Savage's Sure Thing Principle, which we call the *Countable Sure Thing Principle*, as well as an infinitary generalization of von Neumann and Morgenstern's Independence axiom, which we call *Countable (...) Independence*. In violating these principles, they display foibles like those of people who deviate from standard expected utility theory in more mundane cases: they choose dominated strategies, pay to avoid information, and reject expert advice. We precisely characterize the preference relations that satisfy Countable Independence in several equivalent ways: a structural constraint on preferences, a representation theorem, and the principle we began with, that every prospect has a value that some outcome could have.

I examine what the mathematical theory of random structures can teach us about the probability of Plenitude, a thesis closely related to David Lewis's modal realism. Given some natural assumptions, Plenitude is reasonably probable a priori, but in principle it can be (and plausibly it has been) empirically disconfirmed—not by any general qualitative evidence, but rather by our de re evidence.

In Phenomenological Reduction in Heidegger's Sein und Zeit: a New Proposal, Matheson Russell investigates the indebtedness of the Heidegger of Being and Time to Husserl's transcendental phenomenology by way of distinguishing in it differing types of transcendental reduction. He supplies an overview of recent attempts to identify such reductions in order then to propose a new interpretation locating two levels of reduction in Heidegger's fundamental ontology. These concern, first, an enquiry going back to the horizon of 'existence', and, second, one (...) going back to the horizon of 'temporality'. While the first level is argued to be explicit in the published text, the second, Russell claims, lies within the horizon of the unfinished parts of Being and Time. (shrink)

What degrees of belief does Sleeping Beauty's evidence support? That depends.

The new narcissist is haunted not by guilt but by anxiety. He seeks not to inflict his own certainties on others but to find a meaning in life. Liberated from the superstitions of the past, he doubts even the reality of his own existence. Superficially relaxed and tolerant, he finds little use for dogmas of racial and ethnic purity but at the same time forfeits the security of group loyalties and regards everyone as a rival for the favors conferred by (...) a paternalistic state. His sexual attitudes are permissive rather than puritanical, even though his emancipation from ancient taboos brings him no sexual peace. Fiercely competitive in his demand for approval and acclaim, he distrusts competition because he associates it unconsciously with an unbridled urge to destroy. Hence he repudiates the competitive ideologies that flourished at an earlier stage of capitalist development and distrusts even their limited expression in sports and games. He extols cooperation and teamwork while harboring deeply antisocial impulses. He praises respect for rules and regulations in the secret belief that they do not apply to himself. Acquisitive in the sense that his cravings have no limits, he does not accumulate goods and provisions against the future, in the manner of the acquisitive individualist of nineteenth-century political economy, but demands immediate gratification and lives in a state of restless, perpetually unsatisfied desire.

The Preamble to the Charter of Rights and Freedoms claims "Canada is grounded upon principles that recognize the supremacy of God." This claim is hopelessly confused and it has no place in our constitution. This is true, moreover, whether you are a Christian, a Jew, a Muslim, a Pantheist, an atheist, or someone who has never given one moment's thought to "the supremacy of God" -- much less "recognized" it.

In the early eighteenth century context there was an intimate connection between problems concerning the existence of the material world and problems of natural religion. Two issues are of particular importance for understanding Hume’s irreligious intentions in the Treatise. First, if we are unable to establish that we know that the material world exists, then all arguments for the existence of God that presuppose knowledge of the material world (i.e. its beauty, order, design, etc.) are placed in doubt. Second, if (...) we are naturally disposed to believe in the existence of body, but this belief is false, then it seems to follow that God must be a deceiver -- or does not exist. Hume’s arguments in 1.4.2, I maintain, are finely crafted to present both these (irreligious) challenges to the orthodox view. (shrink)
