The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories of experience are responses to this challenge.

We argue that S is in a position to know that p iff S can know that p. Thus, what makes position-to-know-ascriptions true is just a special case of what makes ability-ascriptions true: compossibility. The novelty of our compossibility theory of epistemic modality lies in its subsuming epistemic modality under agentive modality, the modality characterizing what agents can do.

Prior’s Tonk is a famously horrible connective. It is defined by its inference rules. My aim in this article is to compare Tonk with some hitherto unnoticed nasty connectives, which are defined in semantic terms. I first use many-valued truth-tables for classical sentential logic to define a nasty connective, Knot. I then argue that we should refuse to add Knot to our language. And I show that this reverses the standard dialectic surrounding Tonk, and yields a novel solution to the (...) problem of many-valued truth-tables for classical sentential logic. I close by outlining the technicalities surrounding nasty connectives on many-valued truth-tables. (shrink)

We offer two arguments against the halving repose to Sleeping Beauty. First, we show that halving violates the Epistemological Sure-Thing Principle, which we argue is a necessary constraint on any reasonable probability assignment. The constraint is that if hypothetically on C you assign to A the same probability you assign to A hypothetical on not-C, you must assign that probability to A simpliciter. Epistemically, it's a sure thing for you that A has this probability. Second, we show that halving violates (...) solid statistical reasoning (or draws absurdly irrelevant distinctions). (shrink)

Philosophy and model theory frequently meet one another. Philosophy and Model Theory aims to understand their interactions -/- Model theory is used in every ‘theoretical’ branch of analytic philosophy: in philosophy of mathematics, in philosophy of science, in philosophy of language, in philosophical logic, and in metaphysics. But these wide-ranging appeals to model theory have created a highly fragmented literature. On the one hand, many philosophically significant mathematical results are found only in mathematics textbooks: these are aimed squarely at mathematicians; (...) they typically presuppose that the reader has a significant background in mathematics; and little clue is given as to their philosophical significance. On the other hand, the philosophical applications of these results are then scattered across disconnected pockets of papers, separated by decades or more. -/- The first aim of Philosophy and Model Theory, then, is to consider the philosophical uses of model theory. On a technical level, we try to show how philosophically significant results connect to one another, and also to state the best version of a result for philosophical purposes. On a philosophical level, we show how similar dialectical situations arise repeatedly, across fragmented debates in varied philosophical areas. -/- The second aim of Philosophy and Model Theory, though, is to consider the philosophy of model theory. Model theory itself is rarely taken as the subject matter of philosophising (contrast this, say, with the philosophy of biology, or the philosophy of set theory). But model theory is a beautiful part of pure mathematics, and worthy of philosophical study in its own right. (shrink)

Both patients and clinicians frequently report problems around communicating and assessing pain. Patients express dissatisfaction with their doctors and doctors often find exchanges with chronic pain patients difficult and frustrating. This chapter thus asks how we could improve pain communication and thereby enhance outcomes for chronic pain patients. We argue that improving matters will require a better appreciation of the complex meaning of pain terms and of the variability and flexibility in how individuals think about pain. We start by examining (...) the various accounts of the meaning of pain terms that have been suggested within philosophy and suggest that, while each of the accounts captures something important about our use of pain terms, none is completely satisfactory. We propose that pain terms should be viewed as communicating complex meanings, which may change across different communicative contexts, and this in turn suggests that we should view our ordinary thought about pain as similarly complex. We then sketch what a view taking seriously this variability in meaning and thought might look like, which we call the “polyeidic” view. According to this view, individuals tacitly occupy divergent stances across a range of different dimensions of pain, with one agent, for instance, thinking of pain in a much more “bodycentric” kind of way, while another thinks of pain in a much more "mindcentric” way. The polyeidic view attempts to expand the multidimensionality recognised in, e.g., biopsychosocial models in two directions: first, it holds that the standard triumvirate— dividing sensory/cognitive/affective factors— needs to be enriched in order to capture important distinctions within the social and psychological dimensions. Second, the polyeidic view attempts to explain (at least in part) why modulation of experience by these social and psychological factors is possible in the first place. It does so by arguing that because the folk concept of pain is complex, different weightings of the different parts of the concept can modulate pain experience in a variety of ways. Finally, we argue that adopting a polyeidic approach to the meaning of pain would have a range of measurable clinical outcomes. (shrink)

Kotek et al. argue on the basis of novel experimental evidence that sentences like ‘Most of the dots are blue’ are ambiguous, i.e. have two distinct truth conditions. Kotek et al. furthermore suggest that when their results are taken together with those of earlier work by Lidz et al., the overall picture that emerges casts doubt on the conclusions that Lidz et al. drew from their earlier results. We disagree with this characterization of the relationship between the two studies. Our (...) main aim in this reply is to clarify the relationship as we see it. In our view, Kotek et al.’s central claims are simply logically independent of those of Lidz et al.: the former concern which truth condition a certain kind of sentence has, while the latter concern the procedures that speakers choose for the purposes of determining whether a particular truth condition is satisfied in various scenes. The appearance of a conflict between the two studies stems from inattention to the distinction between questions about truth conditions and questions about verification procedures. (shrink)

Tim Crane addresses the ancient question of how it is possible to think about what does not exist. He argues that the representation of the non-existent is a pervasive feature of our thought about the world, and that to understand thought's representational power ('intentionality') we need to understand the representation of the non-existent.

We present nested sequent systems for propositional Gödel-Dummett logic and its first-order extensions with non-constant and constant domains, built atop nested calculi for intuitionistic logics. To obtain nested systems for these Gödel-Dummett logics, we introduce a new structural rule, called the linearity rule, which (bottom-up) operates by linearising branching structure in a given nested sequent. In addition, an interesting feature of our calculi is the inclusion of reachability rules, which are special logical rules that operate by propagating data and/or checking (...) if data exists along certain paths within a nested sequent. Such rules require us to generalise our nested sequents to include signatures (i.e. finite collections of variables) in the first-order cases, thus giving rise to a generalisation of the usual nested sequent formalism. Our calculi exhibit favourable properties, admitting the height-preserving invertibility of every logical rule and the (height-preserving) admissibility of a large collection of structural and reachability rules. We prove all of our systems sound and cut-free complete, and show that syntactic cut-elimination obtains for the intuitionistic systems. We conclude the paper by discussing possible extensions and modifications, putting forth an array of structural rules that could be used to provide a sizable class of intermediate logics with cut-free nested sequent systems.

Elements of Mind provides a unique introduction to the main problems and debates in contemporary philosophy of mind. Author Tim Crane opposes those currently popular conceptions of the mind that divide mental phenomena into two very different kinds (the intentional and the qualitative) and proposes instead a challenging and unified theory of all the phenomena of mind. In light of this theory, Crane engages students with the central problems of the philosophy of mind--the mind-body problem, the problem of intentionality (or (...) mental representation), the problem of consciousness, and the problem of perception--and attempts to find solutions to these problems. A fresh and engaging exploration of the main issues in the philosophy of mind, Elements of Mind is easily accessible to students with no background in the subject. (shrink)

This book on the philosophy of science argues for an empiricism, opposed to the tradition of David Hume, in which singular rather than general causal claims are primary; causal laws express facts about singular causes whereas the general causal claims of science are ascriptions of capacities or causal powers, capacities to make things happen. Taking science as measurement, Cartwright argues that capacities are necessary for science and that these can be measured, provided suitable conditions are met. There are case studies (...) from both econometrics and quantum mechanics. (shrink)

This paper sketches a taxonomy of forms of substantivalism and relationism concerning space and time, and of the traditional arguments for these positions. Several natural sorts of relationism are able to account for Newton's bucket experiment. Conversely, appropriately constructed substantivalism can survive Leibniz's critique, a fact which has been obscured by the conflation of two of Leibniz's arguments. The form of relationism appropriate to the Special Theory of Relativity is also able to evade the problems raised by Field. I survey (...) the effect of the General Theory of Relativity and of plenism on these considerations. (shrink)

This essay is the first act of a two-act play. My ultimate aim is to defend a simple proposition: time passes. To be more precise, I want to defend the claim that the passage of time is an intrinsic asymmetry in the structure of space-time itself, an asymmetry that has no spatial counterpart and is metaphysically independent of the material contents of space-time. It is independent, for example, of the entropy gradient of the universe. This view is part of common-sense, (...) but has been widely attacked by philosophers. The passage of time, we are told, is a myth, an illusion, even an incoherent notion. Because the notion that time passes is common sense, it perhaps requires little positive defence; if there are no weighty objections to the view, it ought to be accepted. So the first, and more important, act of the play is defusing the arguments which have been used to cast doubt on the passage of time. I have positive arguments to give, but not having space for them here, I will confine myself to an examination of the common philosophical arguments that have been used to cast doubt on the passage of time.

Aspects of Psychologism is a penetrating look into fundamental philosophical questions of consciousness, perception, and the experience we have of our mental lives. Psychologism, in Tim Crane’s formulation, presents the mind as a single subject-matter to be investigated not only empirically and conceptually but also phenomenologically: through the systematic examination of consciousness and thought from the subject’s point of view.

Imagine living in the future in a world already damaged by humankind, a world where resources are insufficient to meet everyone's basic needs and where a chaotic climate makes life precarious. Then imagine looking back into the past, back to our own time and assessing the ethics of the early twenty-first century. "Ethics for a Broken World" imagines how the future might judge us and how living in a time of global environmental degradation might utterly reshape the politics and ethics (...) of the future. This book is presented as a series of history of philosophy lectures given in the future, studying the classic texts from a past age of affluence, our own time. The central ethical questions of our time are shown to look very different from the perspective of a ruined world. The aim of "Ethics for a Broken" World is to look at our present with the benefit of hindsight - to reimagine contemporary philosophy in an historical context - and to highlight the contingency of our own moral and political ideals.

Utilitarianism - a philosophy based on the principle of the greatest happiness for the greatest number of people - has been hugely influential over the past two centuries. Beyond ethics or morality, utilitarian assumptions and arguments abound in modern economic and political life, especially in public policy. An understanding of utilitarianism is indeed essential to any understanding of contemporary society. "Understanding Utilitarianism" presents utilitarianism very much as a living tradition. The book begins with a summary of the classical utilitarianism of (...) the eighteenth and nineteenth centuries. Subsequent chapters trace the development of the central themes of utilitarian thought over the twentieth century, covering such questions as: What is happiness? Is happiness the only valuable thing? Is utilitarianism about acts or rules or institutions? Is utilitarianism unjust, or implausibly demanding, or impractical? and Where might utilitarianism go in the future? (shrink)

The meaning and truth conditions for claims about physical modality and causation have been considered problematic since Hume’s empiricist critique. But the underlying semantic commitments that follow from Hume’s empiricism about ideas have long been abandoned by the philosophical community. Once the consequences of that abandonment are properly appreciated, the problems of physical modality and causal locutions fall away, and can be painlessly solved.

Sperm, eggs and embryos are made up of more than genes, and there are indications that changes to non‐genetic structures in these elements of the germline can also be inherited. It is, therefore, a mistake to treat phrases like ‘germline inheritance’ and ‘genetic inheritance’ as simple synonyms, and bioethical discussion should expand its focus beyond alterations to the genome when considering the ethics of germline modification. Moreover, additional research on non‐genetic inheritance draws attention to a variety of means whereby differences (...) can be inherited in offspring generations that do not rely on differences in germline structures. Research on these diverse forms of inheritance challenges the notion that there is some special form of ethical concern that falls on germline interventions in general, and on interventions to the nuclear genome within the germline in particular.

Truth and Paradox largely consists of three connected technical projects together with a more general account of the nature of truth. The first project is the most familiar: providing an account of how logically complex sentences get assigned truth values on the basis of the truth values assigned to the logically atomic sentences. The second is construction of valid, syntactically specifiable inference rules for a language that includes the familiar logical connectives and the truth predicate. The third is an account (...) of the normative rules governing the assertion of sentences. Let me sketch these in order. (shrink)

Abraham Stone recently has published an argument purporting to show that David Bohm's interpretation of quantum mechanics fails to solve the measurement problem. Stone's analysis is not correct, as he has failed to take account of the conditions under which the theorems he cites are proven. An explicit presentation of a Bohmian measurement illustrates the flaw in his reasoning.

Drawing on the author's recent bookEthics for a Broken World, this article explores the philosophical implications of the fact that climate change – or something like it – might lead to abroken worldwhere resources are insufficient to meet everyone's basic needs, and where our affluent way of life is no longer an option. It argues that the broken world has an impact, not only on applied ethics, but also on moral theory. It then explores that impact. The article first argues (...) that the broken world creates severe difficulties for both libertarians and contractualists. It then explores the impact of the broken world on utilitarianism – and especially on reflective equilibrium arguments for rule-utilitarianism. The article concludes that, while such arguments may still be viable, the form of rule-utilitarianism that results will be less moderate and less liberal than contemporary rule-utilitarians might hope.

Our everyday notions of responsibility are often driven by our need to justify ourselves to specific others – especially those we harm, wrong, or otherwise affect. One challenge for contemporary ethics is to extend this interpersonal urgency to our relations with those future people who are harmed or affected by our actions. In this article, I explore our responsibility for climate change by imagining a possible ‘broken future’, damaged by the carbon emissions of previous generations, and then asking what its (...) inhabitants might think of our current behaviour, our moral thinking, and our excuses. In particular, I will focus on a simplified scenario where present people can only avoid a broken future by sacrificing Rawlsian favourable conditions. Suppose we refuse to avoid a broken future, on the grounds that we cannot be expected to make such great sacrifices. If the broken future lacks favourable conditions, will its inhabitants accept our excuses? Will they hold us responsible for things we regard as excusable? If so, should we be guided by their judgements or by our own? (shrink)

Moral theories can be distinguished, not only by the answers they give, but also by the questions they ask. Utilitarianism's central commitment is to the promotion of well-being, impartially considered. This commitment shapes utilitarianism in a number of ways. If scarce resources should be directed where they will best promote well-being, and if theoretical attention is a scarce resource, then moral theorists should focus on topics that are most important to the future promotion of well-being. A theme of this Element (...) is that, as times change, the priorities of utilitarianism also change. Questions that were once theoretical curiosities move centre stage. And themes from earlier utilitarians that have become unfashionable may come to the fore again. Utilitarianism is a living tradition, not an abstract set of timeless principles or a purely historical artefact. (shrink)

ABSTRACT In “Temporal Passage and the ‘No Alternate Possibilities Argument’”, Jonathan Tallant takes up one objection based on the observation that if time passes at the rate of one second per second there is no other possible rate at which it could pass. The argument rests on the premise that if time passes at some rate then it could have passed at some other rate. Since no alternative rate seems to be coherent, one concludes that time cannot pass at all. (...) The obvious weak point of the NAP is the premise itself. (shrink)

Any empirical physical theory must have implications for observable events at the scale of everyday life, even though that scale plays no special role in the basic ontology of the theory itself. The fundamental physical scales are microscopic for the “local beables” of the theory and universal scale for the non-local beables. This situation creates strong demands for any precise quantum theory. This paper examines those constraints, and illustrates some ways in which they can be met.

Utilitarians must think collectively about the future because many contemporary moral issues require collective responses to avoid possible future harms. But current rule utilitarianism does not accommodate the distant future. Drawing on my recent books Future People and Ethics for a Broken World, I defend a new utilitarianism whose central ethical question is: What moral code should we teach the next generation? This new theory honours utilitarianism’s past and provides the flexibility to adapt to the full range of credible futures (...) – from futures broken by climate change to the digital, virtual and predictable futures produced by various possible technologies.

This paper presents hitherto unpublished writings of Kurt Gödel concerning logical, epistemological, theological, and physical antinomies, which he generally considered as “the most interesting facts in modern logic,” and which he used as a basis for his famous metamathematical results. After investigating different perspectives on the notion of the logical structure of the antinomies and presenting two “antinomies of the intensional,” a new kind of paradox closely related to Gödel’s ontological proof for the existence of God is introduced and completed (...) by a compilation of further theological antinomies. Finally, after a presentation of unpublished general philosophical remarks concerning the antinomies, Gödel’s type-theoretic variant of Leibniz’Monadology, discovered in his notes on the foundations of quantum mechanics, is examined. Most of the material presented here has been transcribed from the Gabelsberger shorthand system for the first time. (shrink)

This paper asks how rule‐consequentialism might adapt to very adverse futures, and whether moderate liberal consequentialism can survive into broken futures and/or futures where humanity faces imminent extinction. The paper first recaps the recent history of rule‐consequentialist procreative ethics. It outlines rule‐consequentialism, extends it to cover future people, and applies it to broken futures. The paper then introduces a new thought experiment—the “ending world”—where humanity faces an extinction that is unavoidable and imminent, but not immediate. The paper concludes by explaining (...) why this thought experiment challenges rule‐consequentialism's commitment to procreative liberty, and briefly asking how rule‐consequentialism might respond to that challenge.

Synthetic biology is often described as a project that applies rational design methods to the organic world. Although humans have influenced organic lineages in many ways, it is nonetheless reasonable to place synthetic biology towards one end of a continuum between purely ‘blind’ processes of organic modification at one extreme, and wholly rational, design-led processes at the other. An example from evolutionary electronics illustrates some of the constraints imposed by the rational design methodology itself. These constraints reinforce the limitations of (...) the synthetic biology ideal, limitations that are often freely acknowledged by synthetic biology’s own practitioners. The synthetic biology methodology reflects a series of constraints imposed on finite human designers who wish, as far as is practicable, to communicate with each other and to intervene in nature in reasonably targeted and well-understood ways. This is better understood as indicative of an underlying awareness of human limitations, rather than as expressive of an objectionable impulse to mastery over nature. (shrink)

Kant claims repeatedly that experience involves sensations being ‘ordered and placed’ in space. This paper considers what this surprising claim could possibly mean. After presenting the relevant textual evidence and rejecting two candidate interpretations of it, I defend a qualia or ‘mental paint’ interpretation, according to which experience involves a direct, conscious ‘acquaintance’ with sensations arrayed in a ‘phenomenal space.’ This interpretation allows us to take literally many of Kant's claims about sensation: that it is the matter of both intuition (...) and appearance, that we are conscious of sensation in perception, and that sensible qualities like color are sensations.

The global pandemic needs to mark a turning point for the peoples of Aotearoa New Zealand. How can we make sure that our culturally diverse nation charts an equitable and sustainable path through and beyond this new world? In a less affluent future, how can we ensure that all New Zealanders have fair access to opportunities? One challenge is to preserve the sense of common purpose so critical to protecting each other in the face of Covid-19. How can we centre (...) what we have learnt about resilience within Māori and wider Pacific communities in our reforms? How can public understanding of Covid-19 science create a platform for the future social valuing of expertise? How can we ensure that the impact of Covid-19 in New Zealand results in a more sustainable, and inclusive workforce–for instance by expanding our perceptions of the value of our workers through promoting digital inclusion? To meet these challenges, we must reimagine our existing traditions of thought, breathing new life into perennial concepts and debates. Our paper indicates some of the ways that Philosophy is central to this collective reimagining, highlighting solutions to be found across our rich philosophical traditions. (shrink)

I explore the moral implications of four possible futures: a broken future where our affluent way of life is no longer available; a virtual future where human beings spend their entire lives in Nozick's experience machine; a digital future where humans have been replaced by unconscious digital beings; and a theological future where the existence of God has been proved. These futures affect our current ethical thinking in surprising ways. They raise the importance of intergenerational ethics, alter the balance between (...) competing moral theories, and push morality in a more objective direction. (shrink)

We examine the occurrence of ethicsrelated terms in 10-K annual reports over 1994-2006 and offer empirical observations on the conceptual framework of Erhard et al. 2007). We use a pre-Sarbanes-Oxley sample subset to compare the occurrence of ethics-related terms in our 10-K data with samples from other studies that consider virtue-related phenomena. We find that firms using ethics-related terms are more likely to be "sin" stocks, are more likely to be the object of class action lawsuits, and are more likely (...) to score poorly on measures of corporate governance. The consistency of our results across these alternative measures of ethical behavior suggests that managers who portray their firm as "ethical" in 10-K reports are more likely to be systematically misleading the public. These results are consistent with the integrity-performance paradox. (shrink)

Over the past decade, corporate scandals have proliferated. These scandals, along with the emergence of the #MeToo movement and Environmental, Social, and Corporate Governance (ESG) mandates, have increased the scrutiny of corporations’ ethics culture. How have companies responded in terms of the language appearing in their public ethics documents? We compare the Code of Ethics in 2008 versus 2019 for a sample of S&P 500 firms. For the vast majority of firms, their Code of Ethics lengthened, with the average 2019 (...) code having 29% more words (about 1760 words) than the 2008 average. The language of the codes has also changed. Words such as _bribery, corruption, sustainability, speak up, bullying, slavery,_ and _human rights_ all saw significantly higher usage in the later period. We review possible reasons for the dramatic changes and suggest what questions remain about the motivations behind them. Whether the changes we observe are primarily intrinsically motivated or simply market responses to public pressures is yet to be determined. What is clear from our findings is that society seems to be entering a new age of increasingly moral—or, at least, moralized—corporate governance. (shrink)
