_ Convention_ was immediately recognized as a major contribution to the subject and its significance has remained undiminished since its first publication in 1969. Lewis analyzes social conventions as regularities in the resolution of recurring coordination problems-situations characterized by interdependent decision processes in which common interests are at stake. Conventions are contrasted with other kinds of regularity, and conventions governing systems of communication are given special attention.

Epistemologists have recently proposed a number of norms governing rational inquiry. My aim in this paper is to unify and explain recently proposed norms of inquiry by developing a general account of the conditions under which inquiries are rational, analogous to theories such as evidentialism and reliabilism for rational belief. I begin with a reason-responsiveness conception of rationality as responding correctly to possessed normative reasons. I extend this account with a series of claims about the normative reasons for inquiry that (...) we possess. I apply the account to shed light on two classes of norms that have featured prominently in recent discussions: norms of clutter avoidance forbidding agents from engaging in trivial inquiries, and norms of logical non-omniscience governing properties such as the deductive closure and consistency of an agent's belief state. I conclude with a discussion of the sense in which norms of inquiry should be regarded as epistemic norms. (shrink)

This is a corrected version of the final proofs. I've fixed a number of typos, and corrected a blunder in chapter 4. In chapter 4 I say that 'this is this' is analytic, and 'this is not this' is antonymous. This is inconsistent with what I say in chapter 5, and not what I actually think. Rather, 'this is this' is taugologous, and 'this is not this' is contradictory. Analyticity and autnonmy are sense properties while tautologousness and contradictoriness are formal (...) logical properties. Heading, ToC and Index updated accordingly. (Oxford will make these corrections in their online version and in future print runs.). (shrink)

We apply a familiar distinction from philosophy of language to a class of material artifacts that are sometimes said to “speak”: statues. By distinguishing how statues speak at the locutionary level versus at the illocutionary level, or what they say versus what they do, we obtain the resource for addressing two topics. First, we can explain what makes statues distinct from street art. Second, we can explain why it is mistaken to criticize—or to defend—the continuing presence of statues based only (...) on what they represent. Both explanations are driven by the same core idea: the significance of statues arises primarily from what they do, and not what they say. (shrink)

People are often offended by beliefs, expect apologies for beliefs, apologize for their own beliefs. In many mundane cases, people are morally criticized for their beliefs. Intuitively, then, beliefs seem to sometimes wrong people. Recently, the philosophical literature has picked up on this theme, and has started to discuss it under the heading of doxastic wrongdoing. In this paper we argue that despite the strength of such initial intuitions, at the end of the day they have to be rejected. If (...) it can be ever truthfully asserted that beliefs wrong, this is always derivative – beliefs wrong only in virtue of other things (like evidence-gathering actions) wronging. We distinguish between modest and ambitious doxastic wrongdoing theories (the former deny, while the latter accept, the possibility of a morally wrong yet epistemically permissible belief); we argue that each of these options faces insurmountable problems; and we offer partly debunking explanations of the intuitions purportedly supporting doxastic wrongdoing.

Christian pro-lifers often respond to Thomson’s defense of abortion that the violinist is allowed to die while the embryo is killed. Boonin and McMahan counter that this distinction does not provide an objection to extraction abortions that disconnect embryos and allow them to die. I disagree. I first argue that letting die and killing are not to be distinguished by differences between acts and omissions, moral and immoral motives, intentional or unintentional deaths, and causing or not causing a pathology. I (...) offer a taxonomy in which hysterotomies turn out to be killings. I then argue that if either the placenta is considered an organ of the embryo or the embryo is construed as a part of the pregnant woman, then abortion pills kill rather than allow death. So, assuming that killing people is morally worse than letting them die, extraction abortions can be condemned to the same degree as other abortions. (shrink)

We propose a formal framework for interpretable machine learning. Combining elements from statistical learning, causal interventionism, and decision theory, we design an idealised explanation game in which players collaborate to find the best explanation for a given algorithmic prediction. Through an iterative procedure of questions and answers, the players establish a three-dimensional Pareto frontier that describes the optimal trade-offs between explanatory accuracy, simplicity, and relevance. Multiple rounds are played at different levels of abstraction, allowing the players to explore overlapping causal (...) patterns of variable granularity and scope. We characterise the conditions under which such a game is almost surely guaranteed to converge on a optimal explanation surface in polynomial time, and highlight obstacles that will tend to prevent the players from advancing beyond certain explanatory thresholds. The game serves a descriptive and a normative function, establishing a conceptual space in which to analyse and compare existing proposals, as well as design new and improved solutions. (shrink)

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps (...) sustain the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (shrink)

According to the Principle of Sufficient Reason, every fact has an explanation. An important challenge to this principle is that it risks being a counterexample to itself. What explains why everything needs to be explained? My first goal is to distinguish two broad kinds of answers to this question, which I call “Humean Rationalism” and “Non-Humean Rationalism”. My second goal will be to defend the prospects of Humean Rationalism.

This essay examines the philosophical significance of $\Omega$-logic in Zermelo-Fraenkel set theory with choice (ZFC). The categorical duality between coalgebra and algebra permits Boolean-valued algebraic models of ZFC to be interpreted as coalgebras. The hyperintensional profile of $\Omega$-logical validity can then be countenanced within a coalgebraic logic. I argue that the philosophical significance of the foregoing is two-fold. First, because the epistemic and modal and hyperintensional profiles of $\Omega$-logical validity correspond to those of second-order logical consequence, $\Omega$-logical validity is genuinely (...) logical. Second, the foregoing provides a hyperintensional account of the interpretation of mathematical and metamathematical vocabulary. (shrink)

According to a popular idea, freedom is grounded in orthonomy – the ability to be responsive to normative demands. But how exactly must an agent’s action relate to their reasons in order for this orthonomous relationship to hold? In this paper, I propose a novel explanationist answer to this question. I argue that extant answers – causalism and modalism about orthonomy – fail because they fail to account for the fact that intuitions about freedom and orthonomy track facts about explanation. (...) And these facts cannot be reduced to either causal or modal facts. Instead, I propose that we should understand freedom as grounded in special accidentality-dispersing explanations in terms of normative reasons. The resultant view is to be understood as following a Frankfurtian intuition: only factors that explain action can be relevant to whether the action is free. (shrink)

Why study notations, diagrams, or more broadly the variety of nonverbal “representations” or “signs” that are used in mathematical practice? This chapter maps out recent work on the topic by distinguishing three main philosophical motivations for doing so. First, some work (like that on diagrammatic reasoning) studies signs to recover norms of informal or historical mathematical practices that would get lost if the particular signs that these practices rely on were translated away; work in this vein has the potential to (...) broaden our view of the specific normativity of mathematics beyond logical proof. Second, some work focuses on signs to highlight the open-ended and “nonrigorous” aspects of mathematical practice, and the role of these aspects in the historical development of mathematics. The third motivation is based on the following observation: the reason differences in signs matter in mathematics is that humans are finite agents, with cognitive and computational limitations. Accordingly, studying signs can be a way to study how human computational constraints shape the mathematics that we do, and to tackle the topic of mathematical understanding. (shrink)

According to dispositionalism about modality, a proposition <p> is possible just in case something has, or some things have, a power or disposition for its truth; and <p> is necessary just in case nothing has a power for its falsity. But are there enough powers to go around? In Yates (2015) I argued that in the case of mathematical truths such as <2+2=4>, nothing has the power to bring about their falsity or their truth, which means they come out both (...) necessary and not possible. Combining this with axiom (T), it is easy to derive a contradiction. I suggested that dispositionalists ought to retreat a little and say that <p> is possible just in case either p, or there is a power to bring it about that p, grounding the possibility of mathematical propositions in their truth rather than in powers. Vetter’s (2015) has the resources to provide a response to my argument, and in her (2018) she explicitly addresses it by arguing for a plenitude of powers, based on the idea that dispositions come in degrees, with necessary properties a limiting case of dispositionality. On this view there is a power for <2+2=4>, without there being a power to bring about its truth. In this paper I argue that Vetter’s case for plenitude does not work. However, I suggest, if we are prepared to accept metaphysical causation, a case can be made that there is indeed a power for <2+2=4>. (shrink)

This chapter explores the intersection of experimental philosophy and philosophical logic. It considers a distinction between pure and applied logic. It sketches some ways in which experimental results and empirical results more broadly, can inform and have informed debates within philosophical logic. The chapter lays out a way of looking at the situation that makes plain at least one way in which people should expect experimental and logical concerns to overlap. It turns to the phenomenon of vagueness, where people can (...) see this overlap explored and developed from multiple angles, showing just how intimately related experiment and logic can be. Logic is not only useful for exploring hypotheses about truth conditions and entailments but also for exploring hypotheses about reasoning. Logical and experiment can fruitfully interact in a variety of applications, and that is all people need for experimental philosophical logic to be worthwhile. (shrink)

This paper explores the human experience of game-playing and its implications for artificial intelligence. The author uses phenomenology to examine game-playing from a human-centered perspective and applies it to language games played by artificial intelligences and humans. The paper argues that AI cannot truly play games because it lacks the intentionality, embodied experience, and social interaction that are fundamental to human game-playing. Furthermore, current AI lacks the ability to converse, which is argued to be equivalent to Wittgenstein’s view of engaging (...) in “language games.” The author presents a formal ontology of game playing, agents, and their intentional states, and contrasts human agents playing games with artificial agents “playing games.” The paper concludes that while artificial intelligence can simulate some aspects of human language games, it lacks the essential capacities for game playing, such as cognition, creativity, will, intentionality, understanding, and personhood.

Intuitively speaking, a multiple artwork is one that admits of multiple ‘instances’ which are capable of playing a particular role in the appreciation of the work. The ‘explananda’ in the title of this article are things that have been proposed as requiring explanation by any adequate ontology of multiple artworks so conceived. This assumes that the ontology of art is in the business of explaining certain things, an assumption I defend. At least nine purported explananda have been proposed in the (...) relevant literature. I begin by offering a preliminary sketch of these explananda, identifying how they are grounded in our ordinary artistic practice and discourse, and how they have structured recent debates in the ontology of art. I next argue that the notion of ‘instance’ must be understood in a particular way if instance multiplicity is to capture the standard distinction between singular and multiple art forms. I then assess the relative significance and implications of the nine explananda for an adjudication of the debates in the ontology of art. I identify problems for the historically dominant ‘type’ theory of multiples, and propose an alternative account that speaks to all nine explananda. I conclude by reflecting on where this leaves us and how we should proceed. (shrink)

This article addresses ontological negotiations in the Global South through three case studies of community-based research in Brazil and Ghana. We argue that ontological perspectives of Indigenous and other subjugated communities require an ontological pluralism that recognizes the plurality of both representational tools and ways of being in the world. Locating these two readings of ontological pluralism in the politics of the Global South, the article highlights a wider dynamic from ontological paternalism to ontological diversity to ontological decolonization. We conclude (...) by arguing that this dynamic provides important lessons for reorienting agendas in social ontology through Southern Ontologies. (shrink)

We call beliefs reasonable or unreasonable, justified or unjustified. What does this imply about belief? Does this imply that we are responsible for our beliefs and that we should be blamed for our unreasonable convictions? Or does it imply that we are in control of our beliefs and that what we believe is up to us? Reason Without Freedom argues that the major problems of epistemology have their roots in concerns about our control over and responsibility for belief. David (...) Owens focuses on the arguments of Descartes, Locke and Hume - the founders of epistemology - and presents a critical discussion of the current trends in contemporary epistemology. He proposes that the problems we confront today - scepticism, the analysis of knowlege, and debates on epistemic justification - can be tackled only once we have understood the moral psychology of belief. This can be resolved when we realise that our responsibility for beliefs is profoundly different from our rationality and agency, and that memory and testimony can preserve justified belief without preserving the evidence which might be used to justify it. Reason Without Freedom should be of value to those interested in contemporary epistemology, philosophy of mind and action, ethics, and the history of 17th and 18th century. (shrink)

This paper examines the philosophical significance of the consequence relation defined in the $\Omega$-logic for set-theoretic languages. I argue that, as with second-order logic, the hyperintensional profile of validity in $\Omega$-Logic enables the property to be epistemically tractable. Because of the duality between coalgebras and algebras, Boolean-valued models of set theory can be interpreted as coalgebras. In Section \textbf{2}, I demonstrate how the hyperintensional profile of $\Omega$-logical validity can be countenanced within a coalgebraic logic. Finally, in Section \textbf{3}, the philosophical (...) significance of the characterization of the hyperintensional profile of $\Omega$-logical validity for the philosophy of mathematics is examined. I argue (i) that $\Omega$-logical validity is genuinely logical, and (ii) that it provides a hyperintensional account of formal grasp of the concept of `set'. Section \textbf{4} provides concluding remarks. (shrink)

John Stuart Mill’s justification for British rule in India is well known. Less well known and discussed are Mill’s extensive writings on the practice of British rule in India. A close engagement with Mill’s writings on this issue shows Mill was a much more uncertain and anxious imperialist than he is often presented to be. Mill was acutely aware of the difficulties presented by the imperial context in India, he identified a number of very demanding conditions that would have to (...) be met if Britain’s imperial mission was to be successful, and he was very troubled by the dangers posed to this mission from politics in Britain. Toward the end of his life, Mill become much more pessimistic about the progressive possibilities of British colonialism, in part because of what he thought had happened after the transfer of British rule from the East India Company to the British state. A focus on Mill’s arguments about the practice of British rule in India goes some way to providing a more nuanced account of what Mill thought about colonialism. (shrink)

Do motivational limitations due to human nature constrain the demands of justice? Among those who say no, David Estlund offers perhaps the most compelling argument. Taking Estlund’s analysis of “ability” as a starting point, I show that motivational deficiencies can constrain the demands of justice under at least one common circumstance — that the motivationally-deficient agent makes a good faith effort to overcome her deficiency. In fact, my argument implies something stronger; namely, that the demands of justice are constrained (...) by what people are sufficiently likely to be motivated to do. Thus, contrary to the prevailing wisdom, it is the business of ideal theory — not just nonideal theory — to work with the motivational capacities people are likely enough to have.

What is going on when we are consciously aware of a visual scene, or hear sounds, or otherwise enjoy sensory experience?

Many philosophers of physics think that physical rates of change, like velocity or acceleration in classical physics, are extrinsic. Many philosophers of mind think that phenomenal properties, which characterize what it’s like to be an agent at a time, are intrinsic. I will argue that these two views can’t both be true. Given that these two views are in tension, we face an explanatory challenge. Why should there be any interesting connection between these physical quantities and consciousness in the first (...) place? In a speculative spirit, I close by developing a panpsychist view which promises to explain this connection in a particularly satisfying way. (shrink)

This paper considers the probative burdens of proposing action or policy options in deliberation dialogues. Do proposers bear a burden of proof? Building on pioneering work by Douglas Walton (2010), and following on a growing literature within computer science, the prevailing answer seems to be “No.” Instead, only recommenders—agents who put forward an option as the one to be taken—bear a burden of proof. Against this view, we contend that proposers have burdens of proof with respect to their proposals. Specifically, (...) we argue that, while recommenders that Φ bear a burden of proof to show that □Φ (We should / ought to / must Φ), proposers that Φ have a burden of proof to show that ◇Φ (We may / can Φ). A burden of proposing may be defined as, which reads: Those who propose that we might Φ are obliged, if called upon, to show that Φ is possible in any of four ways which we call worldly, deontic, instrumental, and practical. So understood, burdens of proposing satisfy the standard formal definition of burden of proof. (shrink)

Using as a starting point recent and apparently incompatible conclusions by Saunders and Knox, I revisit the question of the correct spacetime setting for Newtonian physics. I argue that understood correctly, these two versions of Newtonian physics make the same claims both about the background geometry required to define the theory, and about the inertial structure of the theory. In doing so I illustrate and explore in detail the view—espoused by Knox, and also by Brown —that inertial structure is defined (...) by the dynamics governing subsystems of a larger system.

In this paper, I present and analyze Berkeley’s sporadic claims on the animal‒human divide, concentrating on his early works, especially his Notebooks. Before drawing our attention to the importance of imagination, I start by contextualizing Berkeley’s views on animal cognition more generally. More specifically, I aim to clarify that though he verbally agrees with Descartes that animals cannot imagine like we do, Berkeley’s view is motivated by fundamentally different considerations. What he ultimately denies is that animals can imagine in a (...) sense that requires the sort of spontaneous and creative activity we share more with God than animals. (shrink)

Objective: To identify the frequency and nature of care conflict dilemmas that United States long-term care providers encounter, response strategies, and use of ethics resources to assist with dispute resolution. Design: An online cross-sectional survey was distributed to the Society for Post-Acute and Long-Term Care Medicine (AMDA). Results: Two-thirds of participants, primarily medical directors, have rejected surrogate instructions and 71% have managed family conflict. Conflict over treatment decisions and issues interpreting advance directives were frequently reported. Half of facilities lack a (...) formal dispute mediation policy. Only five respondents have called an ethics consult for assistance. Conclusion: Ethically tense care conflicts commonly arise in long-term and post-acute care facilities. Few facility procedures incorporate ethics resources into actual practice. Recommendations are made to create actionable policy, increase access to ethics services, and support staff skill development in order to improve the end-of-life care experiences for patients, families, and care facility staff.

I respond to the frequent objection that structural realism fails to sharply state an alternative to the standard predicate-logic, object / property / relation, way of doing metaphysics. The approach I propose is based on what I call a ‘math-first’ approach to physical theories (close to the so-called ‘semantic view of theories') where the content of a physical theory is to be understood primarily in terms of its mathematical structure and the representational relations it bears to physical systems, rather than (...) as a collection of sentences that attempt to make true claims about those systems (a ‘language-first’ approach). I argue that adopting the math-first approach already amounts to a form of structural realism, and that the choice between epistemic and ontic versions of structural realism is then a choice between a language-first and math-first view of metaphysics; I then explore the status of objects (and properties and relations) in fundamental and non-fundamental physics for both versions of math-first structural realism.

Calling is a very important concept in Christianity. In the medieval era, calling was restricted to ecclesiastical work alone, a devotion to the life of contemplation. Ordinary work or physical labour was not considered qualified to be a calling. Martin Luther was the one who taught that the ordinary work of the ordinary people was also God’s calling and equally spiritual as the ecclesiastical work. However, Miroslav Volf, a Croatian theologian, criticised Luther that his view of calling was too static (...) and irrelevant to the modern context where people often choose to quit a job because of its negative effects and some people have to do multiple jobs in order to make ends meet. While recognising the validity of Volf’s critique, this article seeks to demonstrate that even in the modern context, calling is still a very important theological concept to reflect upon work. Luther’s vocational view of work could be retrieved in discussing the theology of work by putting it in dialogue with Calvin, Kuyper, and other theologians.Contribution: This article seeks to show that the concept of calling is indispensable in constructing a sound theology of work for the modern context. By understanding work as calling, Christian workers are enabled to see how they are participating in God’s redemptive work through their jobs. (shrink)

Between 1873 and 1876, Felix Klein published a series of papers that he later placed under the rubric anschauliche Geometrie in the second volume of his collected works (1922). The present study attempts not only to follow the course of this work, but also to place it in a larger historical context. Methodologically, Klein’s approach had roots in Poncelet’s principle of continuity, though the more immediate influences on him came from his teachers, Plücker and Clebsch. In the 1860s, Clebsch reworked (...) some of the central ideas in Riemann’s theory of Abelian functions to obtain complicated results for systems of algebraic curves, most published earlier by Hesse and Steiner. These findings played a major role in enumerative geometry, whereas Plücker’s work had a strongly qualitative character that imbued Klein’s early studies. A leitmotif in these works can be seen in the interplay between real curves and surfaces as reflected by their transformational properties. During the early 1870s, Klein and Zeuthen began to explore the possibility of deriving all possible forms for real cubic surfaces as well as quartic curves. They did so using continuity methods reminiscent of Poncelet’s earlier approach. Both authors also relied on visual arguments, which Klein would later advance under the banner of intuitive geometry (anschauliche Geometrie). (shrink)

Building Better Health Care Leadership for Canada explains the development and implementation of the Executive Training in Research Application program. Managed and funded by the Canadian Health Services Research Foundation in partnership with the Canadian Medical Association, the Canadian Nursing Association, and the Canadian College of Health Care executives, EXTRA is a two-year national fellowship program that uses the principles of adult learning theory as well as practical projects to educate senior health care leaders in making more consistent use of (...) research evidence in their management roles. Fellows apply the theory learned in residency sessions and educational activities to projects within their home organizations. The authors identify the imperative for better use of evidence, outline the core elements of the curriculum, and capture the real-world experience of regional leaders and fellows involved in making specific changes informed by research-based evidence within their organization.
