Effective Altruism encourages affluent people to make significant donations to improve the wellbeing of the world’s poor, using quantified and observational methods to identify the most efficient charities. Critics argue that EA is inattentive to the systemic causes of poverty and underestimates the effectiveness of individual contributions to systemic change. EA claims to be open to systemic change but suggests that systemic critiques, such as the socialist critique of capitalism, are unhelpfully vague and serve primarily as hypocritical rationalizations of continued (...) affluence. I reformulate the systemic change objection, rebut the charges of vagueness and bad faith and argue that charity may not be worth doing at all from a purely altruistic perspective. In order to take systemic change seriously, EA must repudiate its narrowly empiricist approach, embrace holistic, interpretive social analysis and make inevitably controversial judgments about the complex dynamics of collective action. These kinds of evidence and judgment cannot be empirically verified but are essential to taking systemic change seriously. EA is thereby forced to sacrifice its a-political approach to altruism. I also highlight the importance of quotidian, extra-political contributions to perpetuating or changing harmful social practices. Radical efforts to resist, subvert and reconstruct harmful social practices, such as those involved in economic decision-making, could be just as effective and demanding as charity. But such efforts may be incompatible with extensive philanthropy, because they can require people to retain some level of affluence for strategic reasons but to repudiate both the acquisition of significant wealth and charity as is currently organized. The wealth and status of some critics of charity may indeed be incompatible with effectively contributing to social change, but the altruistic merits of charity are neither as obvious nor as easily demonstrated as EA believes.

The use of vague language in law has important implications for legal theory. Legal philosophers have occasionally grappled with those implications, but they have not come to grips with the characteristic phenomenon of vagueness: the sorites paradox. I discuss the paradox, and claim that it poses problems for some legal theorists. I propose that a good account of vagueness will have three consequences for legal theory: Theories that deny that vagueness in formulations of the law leads to discretion in adjudication (...) cannot accommodate “higher-order” vagueness, A legal theory should accept that the law is partly indeterminate when it can be stated in vague language, However, the traditional formulation of the indeterminacy claim, that a vague statement is “neither true nor false” in a borderline case, is misconceived and should be abandoned.

One of the fundamental components of the concept of economic rationality is that preference orderings are “complete,” i.e., that all alternative actions an economic agent can take are comparable. The idea that all actions can be ranked may be called the single utility assumption. The attractiveness of this assumption is considerable. It would be hard to fathom what choice among alternatives means if the available alternatives cannot be ranked by the chooser in some way. In addition, the efficiency criterion makes (...) sense only if one can infer that an individual's choice reflects the best, in expected welfare terms, among all choices that individual could have made. The possibility that a rearrangement of resources could make someone “better off” without making others “worse off” can be understood only if the post-rearrangement world is comparable with the pre-rearrange-ment world.

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.

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.

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

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.

The book is primarily an essay on the epistemology of the sort of armchair knowledge that we can hope to achieve in philosophy. The possibility of such knowledge is not to be explained by reinterpreting philosophical questions as questions about words or concepts. Although there are philosophical questions about words and concepts, most philosophical questions are not about words or concepts: they are, just as they seem to be, about the things, many of them independent of us, to which the (...) words or concepts refer. Nor is our linguistic or conceptual competence the basis for our philosophical knowledge; such competence merely …. (shrink)

An interview with Timothy Williamson on Modality and other matters. Williams is asked three main questions: the first about the difference between philosophical and non-philosophical knowledge, the second concerns the epistemology of modality, and the third is on the emerging metaphysical picture.

According to the Law of Non–Contradiction, no statement and its negation are jointly true. According to many critics, Christians cannot serve both the orthodox faith and the Law of Non–Contradiction: if they hold to the one they must despise the other. And according to an impressive number of these critics, Christians who cling to the traditional doctrine of the Trinity must despise the Law of Non–Contradiction. Augustine's statement of this doctrine poses the problem as poignantly as any.

The group of Dialectical Theology included some of the most well-known theologians of the 20th century – Karl Barth, Rudolf Bultmann, Friedrich Gogarten, Eduard Thurneysen, Georg Merz und Emil Brunner. In the summer of 1922 they founded the journal Zwischen den Zeiten, which launched Dialectical Theology as the most influential avant-garde movement in Protestantism during the Weimar Republic. Due to internal strife and theological disagreements, the group began to lose strength in the early 1930s and eventually split up and ceased (...) publishing Zwischen den Zeiten in 1933. The individual members later became fierce critics of each other’s theological works. Gogarten and Barth became arch enemies during the so-called “church struggle”, and Bultmann and Barth became each other’s nemesis in the Federal Republic of Germany.In this article I examine the rise and fall of this movement. I argue that the concept “generation” was central to the early self-understanding and selfjustification of the group. It allowed the group to forge an alliance and oppose an antagonistic group of influential theologians. The claim to speak up for a young generation of theologians and pastors – in opposition to an older, liberal generation – became the rallying cry for Dialectical Theology. Further, I argue that conferences, not only the theological writings, played a central, constitutive role in establishing the group as a theological movement. It was at conferences that the members of Dialectical Theology could challenge the older generation and assert their own theological stance. Instead of merely concentrating on the published theological writings of each of the members, I thus argue that one must additionally focus on the applied concepts and the role of conferences to understand the history of Dialectical Theology. It is only when we include these additional contexts that we understand how Dialectical Theology was able to be launched and sustained as a theological movement despite the irreconcilable differences amongst the members.

The traditional view of divine conservation holds that it is simply a continuation of the initial act of creation. In this essay, I defend the continuous-creation tradition against William Lane Craig's criticism that continuous creation fundamentally misconstrues the intuitive distinction between creation and conservation. According to Craig, creation is the unique causal activity of bringing new patient entities into existence, while conservation involves acting upon already existing patient entities to cause their continued existence. I defend continuous creation by challenging Craig's (...) intuitive distinction and by showing that the alternative account of creation and conservation he bases upon it is fraught with serious internal difficulties.

One standard criticism of the doctrine of continuous creation is that it entails the occasionalist position that God alone is a true cause and that the events we commonly identify as causes are merely the occasions upon which God brings about effects. I begin by clearly stating Malebranche's argument from continuous creation to occasionalism. Next, I examine two strategies for resisting Malebranche's argument ??? strong and weak concurrentism ??? and argue that weak concurrentism is the more promising strategy. Finally, I (...) argue that weak concurrentism requires a necessitarian approach to secondary causation. (shrink)

This paper explains and defends the idea that metaphysical necessity is the strongest kind of objective necessity. Plausible closure conditions on the family of objective modalities are shown to entail that the logic of metaphysical necessity is S5. Evidence is provided that some objective modalities are studied in the natural sciences. In particular, the modal assumptions implicit in physical applications of dynamical systems theory are made explicit by using such systems to define models of a modal temporal logic. Those assumptions (...) arguably include some necessitist principles. -/- Too often, philosophers have discussed ‘metaphysical’ modality — possibility, contingency, necessity — in isolation. Yet metaphysical modality is just a special case of a broad range of modalities, which we may call ‘objective’ by contrast with epistemic and doxastic modalities, and indeed deontic and teleological ones (compare the distinction between objective probabilities and epistemic or subjective probabilities). Thus metaphysical possibility, physical possibility and immediate practical possibility are all types of objective possibility. We should study the metaphysics and epistemology of metaphysical modality as part of a broader study of the metaphysics and epistemology of the objective modalities, on pain of radical misunderstanding. Since objective modalities are in general open to, and receive, natural scientific investigation, we should not treat the metaphysics and epistemology of metaphysical modality in isolation from the metaphysics and epistemology of the natural sciences. -/- In what follows, Section 1 gives a preliminary sketch of metaphysical modality and its place in the general category of objective modality. Section 2 reviews some familiar forms of scepticism about metaphysical modality in that light. Later sections explore a few of the many ways in which natural science deals with questions of objective modality, including questions of quantified modal logic. (shrink)

What is belief? "Beliefs aim at truth" is the commonly accepted starting point for philosophers who want to give an adequate account of this fundamental state of mind, but it raises as many questions as it answers. For example, in what sense can beliefs be said to have an aim of their own? If belief aims at truth, does it mean that reasons to believe must also be based on truth? Must beliefs be formed on the basis of evidence alone? (...) Is truth the constitutive norm of belief? Does aiming at truth bring in a normative dimension to the nature of belief? How can the aim of truth guide the formation of our beliefs? In what ways do partial beliefs aim at truth? Is truth the aim of epistemic justification? Last but not least, is it knowledge rather than truth which is the fundamental aim of belief? In recent years, pursuing these questions has proved extremely fertile for our understanding of a wide range of current issues in philosophy of mind and action, epistemology, and meta-ethics. The Aim of Belief is the first book to be devoted to this fast-growing topic. It brings together eleven newly commissioned essays by leading authors on the aim of belief. Contributors: Jonathan Adler, Krister Bykvist, Timothy Chan, Pascal Engel, Kathrin Glüer, Anandi Hattiangadi, Michael Hicks, Paul Horwich, David Papineau, Andrew Reisner, Asbjørn Steglich-Petersen, Ralph Wedgwood, Åsa Wikforss, Daniel Whiting.

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)

This paper aims to identify the constitutive rule of assertion, conceived by analogy with the rules of a game. That assertion has such rules is by no means obvious; perhaps it is more like a natural phenomenon than it seems. One way to find out is by supposing that it has such rules, in order to see where the hypothesis leads and what it explains. That will be done here. The hypothesis is not perfectly clear, of course, but we have (...) at least a crude conception of constitutive rules, which we may refine as we elaborate the hypothesis. Although no attempt will be made here to define ‘rule’, some remarks on constitutive rules will focus the discussion. (shrink)

In the January 6, 1991, issue of the Washington Post Magazine, reporter Walt Harrington wrote a profile of Bryan Stevenson. Mr. Stevenson is a 31-year-old working-class African-American from Delaware who graduated from Harvard Law School and the Kennedy School of Government.

He does this living a Spartan existence on a salary of $24,000, refusing even the $50,000 directorship salary offered to him. (shrink)

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)

The claim that a miracle is a violation of a law of nature has sometimes been used as part of an a priori argument against the possibility of miracle, on the grounds that a violation is conceptually impossible. I criticize these accounts but also suggest that alternative accounts, when phrased in terms of laws of nature, fail to provide adequate conceptual space for miracles. It is not clear what a ???violation??? of a law of nature might be, but this is (...) not relevant to the question of miracles. In practice, accounts of miracle tend to be phrased in terms of God's act not in terms of laws of nature. Finally, I suggest that the a priori argument reflects an intellectual commitment that is widely held, though wrongly built into the argument itself. (shrink)

Having set global warming in irreversible motion, we are facing the possibility of ecological catastrophe. But the environmental emergency is also a crisis for our philosophical habits of thought, confronting us with a problem that seems to defy not only our control but also our understanding. Global warming is perhaps the most dramatic example of what Timothy Morton calls “hyperobjects”—entities of such vast temporal and spatial dimensions that they defeat traditional ideas about what a thing is in the first (...) place. In this book, Morton explains what hyperobjects are and their impact on how we think, how we coexist with one another and with nonhumans, and how we experience our politics, ethics, and art. Moving fluidly between philosophy, science, literature, visual and conceptual art, and popular culture, the book argues that hyperobjects show that the end of the world has already occurred in the sense that concepts such as world, nature, and even environment are no longer a meaningful horizon against which human events take place. Instead of inhabiting a world, we find ourselves inside a number of hyperobjects, such as climate, nuclear weapons, evolution, or relativity. Such objects put unbearable strains on our normal ways of reasoning. Insisting that we have to reinvent how we think to even begin to comprehend the world we now live in, _Hyperobjects_ takes the first steps, outlining a genuinely postmodern ecological approach to thought and action.

This article endeavors to identify the strongest versions of the two primary arguments against epistemic scientific realism: the historical argument—generally dubbed “the pessimistic meta-induction”—and the argument from underdetermination. It is shown that, contrary to the literature, both can be understood as historically informed but logically validmodus tollensarguments. After specifying the question relevant to underdetermination and showing why empirical equivalence is unnecessary, two types of competitors to contemporary scientific theories are identified, both of which are informed by science itself. With the (...) content and structure of the two nonrealist arguments clarified, novel relations between them are uncovered, revealing the severity of their collective threat against epistemic realism and its “no-miracles” argument. The final section proposes, however, that the realist’s axiological tenet “science seeks truth” is not blocked. An attempt is made to indicate the promise for a nonepistemic, purely axiological scientific realism—here dubbed “Socratic scientific realism.”. (shrink)

Assertions are praised as true, informative, relevant, sincere, warranted, well-phrased, or polite. They are criticized as false, uninformative, irrelevant, insincere, unwarranted, ill-phrased, or rude. Sometimes they deserve such praise or criticism. If any respect in which performances of an act can deserve praise or criticism is a norm for that act, then the speech act of assertion has many norms. So has almost any act; jumps can deserve praise as long or brave, criticism as short or cowardly. But it is (...) natural to suppose that some norms are more intimately connected to the nature of asserting than any norm is to the nature of jumping. One might suppose, for example, that someone who knowingly asserts a falsehood has thereby broken a rule of assertion, much as if he had broken a rule of a game; he has cheated. On this view, the speech act, like a game and unlike the act of jumping, is constituted by rules. Thus, not all norms for assertion are on a par. Norms such as relevance, good phrasing, and politeness are just applications of more general cognitive or social norms to the specific act of assertion. Perhaps the norm of informativeness results from a more complex interaction between a general norm of cooperativeness and the nature of assertion as a source of information. But on this view, not all norms for assertion derive from more general norms; otherwise nothing would differentiate it from other speech acts. (shrink)

Introduction : critical thinking -- Thinking big -- Dark thoughts -- Forward thinking.

Timothy Chappell’s new translation of the Theaetetus is presented here in short sections of text, each preceded by a summary of the argument and followed by his philosophical commentary on it. Introductory remarks discuss Plato and his works, his use of dialogue, the structure of the Theaetetus, and alternative interpretations of the work as a whole. A glossary and bibliography are provided.

The scientific realism debate has now reached an entirely new level of sophistication. Faced with increasingly focused challenges, epistemic scientific realists have appropriately revised their basic meta-hypothesis that successful scientific theories are approximately true: they have emphasized criteria that render realism far more selective and, so, plausible. As a framework for discussion, I use what I take to be the most influential current variant of selective epistemic realism, deployment realism. Toward the identification of new case studies that challenge this form (...) of realism, I break away from the standard list and look to the history of celestial mechanics, with an emphasis on twentieth century advances. I then articulate two purely deductive arguments that, I argue, properly capture the historical threat to realism. I contend that both the content and form of these novel challenges seriously threaten selective epistemic realism. I conclude on a positive note, however, arguing for selective realism at a higher level. Even in the face of threats to its epistemic tenet, scientific realism need not be rejected outright: concern with belief can be bracketed while nonetheless advocating core realist tenets. I show that, in contrast with epistemic deployment realism, a purely axiological scientific realism can account for key scientific practices made salient in my twentieth century case studies. And embracing the realists favored account of inference, inference to the best explanation, while pointing to a set of the most promising alternative selective realist meta-hypothesis, I show how testing the latter can be immensely valuable to our understanding of science.

Of all the cases made against classical logic, Michael Dummett's is the most deeply considered. Issuing from a systematic and original conception of the discipline, it constitutes one of the most distinctive achievements of twentieth century British philosophy. Although Dummett builds on the work of Brouwer and Heyting, he provides the case against classical logic with a new, explicit and general foundation in the philosophy of language. Dummett's central arguments, widely celebrated if not widely endorsed, concern the implications of the (...) relation between meaning and use for both the inference rules that govern logical connectives and the relation between truth and its recognition. It is less often noted that Dummett has a further argument against classical logic, one based on the semantic and set-theoretic paradoxes. That is the topic of this paper. (shrink)

Philosophical and scientific investigations of the proprietary aspects of self—mineness or mental ownership—often presuppose that searching for unique constituents is a productive strategy. But there seem not to be any unique constituents. Here, it is argued that the “self-specificity” paradigm, which emphasizes subjective perspective, fails. Previously, it was argued that mode of access also fails to explain mineness. Fortunately, these failures, when leavened by other findings (those that exhibit varieties and vagaries of mineness), intimate an approach better suited to searching (...) for an explanation. Having an alternative in hand, one that shows promise of achieving explanatory adequacy, provides an additional reason to suspend the search for unique constituents. In short, a negative and a positive thesis are developed: we should cease looking for unique constituents and should seek to explain mineness in accord with the model developed here. This model rejects attempts to explain the phenomenon in terms of either a narrative or a minimal sense of self; it seeks to explain at a “molecular” level, one that appeals to multiple, interacting dimensions. The molecular-level model allows for the possibility that subjective perspective is distinct from a stark perspective (one that does not imply mineness). It proposes that the confounding of tacit expectations plays an important role in explaining mental ownership and its complement, disownership. But the confounding of tacit expectations is not sufficient. Because we are able to be aware of the existence of mental states that do not belong to self, we require a mechanism for determining degree of self-relatedness. One such mechanism is proposed here, and it is shown how this mechanism can be integrated into a general model of mental ownership. In the spirit of suggesting how this model might be able to help resolve outstanding problems, the question as to whether inserted thoughts belong to the patient who reports them is also considered.

Until recently, many philosophers took Causal Decision Theory to be more successful than its rival, Evidential Decision Theory. Things have changed, however, with a renewed concern that cases involving an extreme form of decision instability are counterexamples to CDT :392–403, 1984; Egan in Philos Rev 116:93–114, 2007). Most prominent among those cases of extreme decision instability is the Psychopath Button, due to Andy Egan; in that case, CDT recommends a seemingly absurd act that almost certainly results in your death. This (...) renewed attention to decision instability has spurned an array of modifications to and rejections of CDT. I argue, however, that the Psychopath Button and its ilk are no counterexamples to CDT. That is, given the causalist’s commitments in Newcomb Problems, they already have the tools to justify CDT’s verdict in Egan-style cases of extreme decision instability. I first argue that there is no reason to think the Psychopath Button is a counterexample to CDT; in particular, many philosophers have placed too much weight on pre-theoretic intuition in Egan-cases, and apart from pre-theoretic intuition, arguments against CDT in cases of extreme decision instability are flawed. My second claim is that the causalist can provide good reasons for following CDT in cases of extreme decision instability. I present a new case, the Two Button Defense, that highlights precisely why the causalist can reasonably follow CDT in even the Psychopath Button. CDT therefore stands as a viable decision theory, without need for modification, restriction, or rejection. (shrink)

To desire is to be in a particular state of mind. It is a state of mind familiar to everyone who has ever wanted to drink water or desired to know what has happened to an old friend, but its familiarity does not make it easy to give a theory of desire. Controversy immediately breaks out when asking whether wanting water and desiring knowledge are, at bottom, the same state of mind as others that seem somewhat similar: wishing never to (...) have been born, preferring mangoes to peaches, craving gin, having world conquest as one's goal, having a purpose in sneaking out to the shed, or being inclined to provoke just for the sake of provocation. These varied states of mind have all been grouped together under the heading of ‘pro attitudes’, but whether the pro attitudes are fundamentally one mental state or many is disputed. (shrink)
