We begin by showing that every theory of the value of uncertain prospects must have one of three unpalatable properties. _Reckless_ theories recommend giving up a sure thing, no matter how good, for an arbitrarily tiny chance of enormous gain; _timid_ theories permit passing up an arbitrarily large potential gain to prevent a tiny increase in risk; _non-transitive_ theories deny the principle that, if A is better than B and B is better than C, then A must be better than (...) C. Having set up this trilemma, we study its horns. Non-transitivity has been much discussed; we focus on drawing out the costs and benefits of recklessness and timidity when it comes to axiology, decision theory, and normative uncertainty. (shrink)

Numerous approaches to a quantum theory of gravity posit fundamental ontologies that exclude spacetime, either partially or wholly. This situation raises deep questions about how such theories could relate to the empirical realm, since arguably only entities localized in spacetime can ever be observed. Are such entities even possible in a theory without fundamental spacetime? How might they be derived, formally speaking? Moreover, since by assumption the fundamental entities cannot be smaller than the derived and so cannot ‘compose’ them in (...) any ordinary sense, would a formal derivation actually show the physical reality of localized entities? We address these questions via a survey of a range of theories of quantum gravity, and generally sketch how they may be answered positively. (shrink)

This is an opinionated guide to the literature on epistemic dilemmas. It discusses seven kinds of situations where epistemic dilemmas appear to arise; dilemmic, dilemmish, and non-dilemmic takes on them; and objections to dilemmic views along with dilemmist’s replies to them.

Epistemologists often appeal to the idea that a normative theory must provide useful, usable, guidance to argue for one normative epistemology over another. I argue that this is a mistake. Guidance considerations have no role to play in theory choice in epistemology. I show how this has implications for debates about the possibility and scope of epistemic dilemmas, the legitimacy of idealisation in Bayesian epistemology, uniqueness versus permissivism, sharp versus mushy credences, and internalism versus externalism.

This article compares the concept of habitus, as formulated in the work of Mauss and Bourdieu, with the concept of habit, as formulated in the work of Merleau-Ponty and Dewey. The rationale for this, on one level, is to seek to clarify these concepts and any distinction that there may be between them – though the article notes the wide variety of uses of both concepts and suggests that these negate the possibility of any definitive definitions or contrasts. More centrally, (...) however, the purpose of the comparison is to draw out a number of important issues and debates which, it is argued, further work must address if the concepts of habit and habitus are to continue to prove useful and illuminating in social science.

Epistemologists spend a great deal of time thinking about how we should respond to our evidence. They spend far less time thinking about the ways that evidence can be acquired in the first place. This is an oversight. Some ways of acquiring evidence are better than others. Many normative epistemologies struggle to accommodate this fact. In this article I develop one that can and does. I identify a phenomenon – epistemic feedback loops – in which evidence acquisition has gone awry, (...) with the result that even beliefs based on the evidence are irrational. Examples include evidence acquired under the influence of confirmation bias and evidence acquired under the influence of cognitively penetrated experiences caused by implicit bias. I then develop a theoretical framework which enables us to understand why beliefs that are the outputs of epistemic feedback loops are irrational. Finally, I argue that many popular approaches to epistemic normativity may need to be abandoned on the grounds that they cannot comfortably explain feedback loops. The scope of this last claim is broad: it includes almost all contemporary theories of justified/rational belief and of the epistemology of cognitive penetration. (shrink)

Daniel Greco (forthcoming) argues that there cannot be epistemic dilemmas. I argue that he is wrong. I then look in detail at a would-be epistemic dilemma and argue that no non-dilemmic approach to it can be made to work. Along the way, there is discussion of octopuses, lobsters, and other ‘inscrutable cognizers’; the relationship between evaluative and prescriptive norms; a failed attempt to steal a Brueghel; epistemic and moral blame and residue; an unbearable guy who thinks he’s God’s gift to (...) women; excuses; stupid games involving hats; radical permissivism; how I’ll never be able to afford to buy a house in Hampstead; and many other exciting topics.

This article provides an algebraic study of the propositional system $\mathtt {InqB}$ of inquisitive logic. We also investigate the wider class of $\mathtt {DNA}$ -logics, which are negative variants of intermediate logics, and the corresponding algebraic structures, $\mathtt {DNA}$ -varieties. We prove that the lattice of $\mathtt {DNA}$ -logics is dually isomorphic to the lattice of $\mathtt {DNA}$ -varieties. We characterise maximal and minimal intermediate logics with the same negative variant, and we prove a suitable version of Birkhoff’s classic variety (...) theorems. We also introduce locally finite $\mathtt {DNA}$ -varieties and show that these varieties are axiomatised by the analogues of Jankov formulas. Finally, we prove that the lattice of extensions of $\mathtt {InqB}$ is dually isomorphic to the ordinal $\omega +1$ and give an axiomatisation of these logics via Jankov $\mathtt {DNA}$ -formulas. This shows that these extensions coincide with the so-called inquisitive hierarchy of [9].1. (shrink)

The point of departure for this article is the observation that, despite his own personal involvement as an engaged intellectual, Pierre Bourdieu offers a very thin account of social movement activism, and one pre-empted by the rather limited concept of ‘crisis’. The aim of the article, however, is to argue that the central concepts of Bourdieu’s theory of practice can be used to provide an effective and interesting basis for the analysis of social movements, protest and contention. To this end (...) the article demonstrates how the concepts of habitus, capital and field, in particular, resonate with important findings from the social movement literature. The focus of the article is limited to an engagement with Bourdieu. It connects with other work by the author, however, in which he has argued that Bourdieu’s framework can be used to address very serious problems in social movement theory. (shrink)

According to one understanding of the problem of dirty hands, every case of dirty hands is an instance of moral conflict, but not every instance of moral conflict is a case of dirty hands. So, what sets the two apart? The dirty hands literature has offered widely different answers to this question but there has been relatively little discussion about their relative merits as well as challenges. In this paper I evaluate these different accounts by making clear which understanding of (...) concept distinctness underlies them and which of them is, ultimately, the most plausible one in the case of dirty hands and ordinary moral conflict. In order to do so, I will borrow from the terminology employed in recent debates in the philosophy of evil which have tackled a similar problem to the one at hand, i.e. defining what sets evil apart from ordinary wrongdoing. Here it has been argued that concepts could be distinct in three ways: they can have a quantitative difference, a strong qualitative or a moderate qualitative difference. I conclude that the most convincing definition of dirty hands draws a moderate qualitative distinction between ordinary moral conflict according to which dirty hands are those moral conflicts that involve a serious violation or betrayal of a core moral value.

A deductive system is said to be structurally complete if its admissible rules are derivable. In addition, it is called hereditarily structurally complete if all its extensions are structurally complete. Citkin (1978) proved that an intermediate logic is hereditarily structurally complete if and only if the variety of Heyting algebras associated with it omits five finite algebras. Despite its importance in the theory of admissible rules, a direct proof of Citkin’s theorem is not widely accessible. In this paper we offer (...) a self-contained proof of Citkin’s theorem, based on Esakia duality and the method of subframe formulas. As a corollary, we obtain a short proof of Citkin’s 2019 characterization of hereditarily structurally complete positive logics. (shrink)

In this paper we define the notion of frame based formulas. We show that the well-known examples of formulas arising from a finite frame, such as the Jankov-de Jongh formulas, subframe formulas and cofinal subframe formulas, are all particular cases of the frame based formulas. We give a criterion for an intermediate logic to be axiomatizable by frame based formulas and use this criterion to obtain a simple proof that every locally tabular intermediate logic is axiomatizable by Jankov-de Jongh formulas. (...) We also show that not every intermediate logic is axiomatizable by frame based formulas. (shrink)

Recent research suggests that language evolution is a process of cultural change, in which linguistic structures are shaped through repeated cycles of learning and use by domain-general mechanisms. This paper draws out the implications of this viewpoint for understanding the problem of language acquisition, which is cast in a new, and much more tractable, form. In essence, the child faces a problem of induction, where the objective is to coordinate with others (C-induction), rather than to model the structure of the (...) natural world (N-induction). We argue that, of the two, C-induction is dramatically easier. More broadly, we argue that understanding the acquisition of any cultural form, whether linguistic or otherwise, during development, requires considering the corresponding question of how that cultural form arose through processes of cultural evolution. This perspective helps resolve the “logical” problem of language acquisition and has far-reaching implications for evolutionary psychology. (shrink)

I want to review some ways in which Quantum Mechanics seems to affront our “common-sense” notions of identity. Let’s start with a list.

ABSTRACTIn ‘The Principles of Art’, R. G. Collingwood argues that art is the imaginative expression of emotion. So much the worse, then, for Collingwood. The theory seems hopelessly inadequate to the task of capturing art’s extension: of encompassing all the works we generally suppose should be rounded up under the concept. A great number of artworks, and several art forms, have nothing to do with emotion. But it would be surprising were Collingwood philistine enough to think that art is only (...) ever concerned with communicating quotidian affective states, like anger, fear or love. Surely he has some more sophisticated notion of emotion in mind, and quite probably of expression too. And it turns out that those sophisticated notions can be pushed towards a version of the expression theory that meets the extensional challenge. If we interpret Collingwood as saying that expression is a particular application of imagination, and that imagination is the faculty that refines ideas of emotions, and that ‘emotions’... (shrink)

This is a brief response to Loïc Wacquant’s article, ‘Homines in extremis’. The response makes four contributions. First, I consider some of the reasons for the confusion surrounding the habitus concept, arguing that this confusion may be lessened (without any obvious loss) if we revert to ‘habit’ or ‘disposition’. Second, I argue that, irrespective of these terminological quibbles, it is vital that we do not conflate ‘habitus’ and ‘embodied actor’ as some accounts do. There is more to the embodied actor (...) than her habits and she can only have habits because this is so. Third, I begin to explore the point of view offered by ‘carnal ethnography’ and call for further clarification of that point of view. Finally, I note that Wacquant’s ethnography has the effect of rendering certain of Bourdieu’s ideas in a more concrete manner and foregrounding sociability, which the latter is sometimes inclined to ignore. This, I suggest, is a positive development. (shrink)

Drawing upon ethnographic data, this article analyses 'vocabularies of motive' amongst individuals who work out at a private health club in the Greater Manchester area (UK). The article draws a distinction between motives for starting at a gym and motives for continuing, and analyses each separately. It also seeks to draw out, in the latter case, the many motives which conflict with a stereotypical view of 'working out' found in some academic accounts. Working out is not only an instrumental means (...) of cultivating valued bodily attributes, it is argued, nor are its attractions necessarily all 'bodily' (at least narrowly defined) in nature.

We show that every proper normal extension of the bi-modal system S5 2 has the poly-size model property. In fact, to every proper normal extension L of S5 2 corresponds a natural number b(L) - the bound of L. For every L, there exists a polynomial P(·) of degree b(L) + 1 such that every L-consistent formula is satisfiable on an L-frame whose universe is bounded by P(||), where || denotes the number of subformulas of . It is shown that (...) this bound is optimal. (shrink)

The problem of dirty hands is, roughly speaking, concerned with situations in which an agent is faced with a choice between two evils so that, no matter what they do, they will have to violate something of important moral value. Theorists have been primarily concerned with dirty hands choices arising in politics because they are thought to be particularly frequent and pressing in this sphere. Much of the subsequent discussion in the literature has focused on the impact that such choices (...) have on a well-functioning democracy and how, if at all, we can ensure that a politician dirtying their hands does not undermine core democratic values and processes. A particular concern has been whether dirty-handed politicians ought to publicly reveal their actions after the fact and whether they should be held accountable through some form of punishment. The first aim of this paper is to point out that the focus on what is required in the wake of a dirty-handed decision, based on the need to protect the democratic system ought to be balanced with a genuine concern for reparative justice and what is owed to the victims of dirty hands. In the second part of this paper, I then examine the suitability of one common way in which perpetrators partly repair the damage they have done to victims, namely apologizing, in the dirty hands context.

It is common to allocate scarce health care resources by maximizing QALYs per dollar. This approach has been attacked by disability-rights advocates, policy-makers, and ethicists on the grounds that it unjustly discriminates against the disabled. The main complaint is that the QALY-maximizing approach implies a seemingly unsatisfactory conclusion: other things being equal, we should direct life-saving treatment to the healthy rather than the disabled. This argument pays insufficient attention to the downsides of the potential alternatives. We show that this sort (...) of discrimination is one of four unpalatable consequences that any approach to priority setting in health care must face. We argue that, given the alternatives, it is far from clear that we should revise the QALY-maximizing approach in response to this objection. (shrink)

We establish the dichotomy property for stable canonical multi-conclusion rules for IPC, K4, and S4. This yields an alternative proof of existence of explicit bases of admissible rules for these logics.

We conduct a case study analysis of a proposal for the emergence of time based upon the approximate derivation of three grades of temporal structure within an explicit quantum cosmological model which obeys a Wheeler-DeWitt type equation without an extrinsic time parameter. Our main focus will be issues regarding the consistency of the approximations and derivations in question. Our conclusion is that the model provides a self-consistent account of the emergence of chronordinal, chronometric and chronodirected structure. Residual concerns relate to (...) explanatory rather than consistency considerations. (shrink)

We generalize the notion of a monadic algebra to that of a pseudomonadic algebra. In the same way as monadic algebras serve as algebraic models of epistemic modal system S5, pseudomonadic algebras serve as algebraic models of doxastic modal system KD45. The main results of the paper are: Characterization of subdirectly irreducible and simple pseudomonadic algebras, as well as Tokarz's proper filter algebras; Ordertopological representation of pseudomonadic algebras; Complete description of the lattice of subvarieties of the variety of pseudomonadic algebras.

This chapter explores insights concerning the relations among imagination, imagined selves, and knowledge of one’s own self that are to be found in Fernando Pessoa’s The Book of Disquiet. The insights are explored via close reading of the text and comparison with contemporaries of Pessoa. First, a tempting account of the importance of imagination in The Book of Disquiet is set out. On this reading, Pessoa is immersed in miasmatic boredom, but able to temporarily rise above it through the restorative (...) powers of escapist imagination. But, it is suggested, Pessoa neither enjoys his prolific imaginings, nor returns from them restored. It is argued that Pessoa’s disquiet owes to failures of imagination; the book presents a sharp contrast between Pessoa’s keen awareness of the importance of a successful, active imaginative life, and his failure to maintain such a thing. It is further argued that these failures point us towards a better account of imagination’s importance to Pessoa, an account that both prefigures and goes beyond Sartre’s ideas about the relations between nothingness, imagination, and self-consciousness.

In this paper we critically review the various attempts that have been made to understand quantum field theory. We focus on Teller's (1990) harmonic oscillator interpretation, and Bohm et al.'s (1987) causal interpretation. The former unabashedly aims to be a purely heuristic account, but we show that it is only interestingly applicable to the free bosonic field. Along the way we suggest alternative models. Bohm's interpretation provides an ontology for the theory--a classical field, with a quantum equation of motion. This (...) too has problems; it is not Lorentz invariant. (shrink)

We give alternative characterizations of exact, extendible and projective formulas in intuitionistic propositional calculus IPC in terms of n-universal models. From these characterizations we derive a new syntactic description of all extendible formulas of IPC in two variables. For the formulas in two variables we also give an alternative proof of Ghilardi’s theorem that every extendible formula is projective.

I reply to some recent comments by Brian Weatherson on my 'simulation argument'. I clarify some interpretational matters, and address issues relating to epistemological externalism, the difference from traditional brain-in-a-vat arguments, and a challenge based on 'grue'-like predicates.

Electronic dance music has much about it to interest philosophers. In this article, I explore facets of dance music cultures, using the issue of authenticity as a framing question. The problem of sorting real or authentic dance music from mainstream or commercial clubbing can be treated as a matter of history and genre-definition; as a matter of defining scenes or subcultures; and as a matter of blackness. In each case, electronic dance music, and critical discourse surrounding it, offers fresh illumination (...) of aesthetic questions. I briefly characterise the main genres of dance music, match conversations about the hardcore continuum with philosophers’ accounts of genre, survey sociologists’ ways of thinking about cultures and their connections to taste and personal identity, and link criticisms that dance music now lacks blackness to conceptions of black aesthetics. This article is Part I of two; Part II focusses on dancers, DJs, and the aesthetics and ontology of dance music itself. Video abstract. (shrink)

It is often argued that the requirement that moral obligations be ‘action guiding’ motivates the claim that one can be obligated to ϕ only if one can ϕ. I argue that even on its most plausible interpretation, this argument fails, since the reasoning behind it leads to the absurd conclusion that one is permitted to ϕ if one cannot ϕ.

Recently, two apparently quite different duality-based approaches to automata minimisation have appeared. One is based on ideas that originated from the controllability-observability duality from systems theory, and the other is based on ideas derived from Stone-type dualities specifically linking coalgebras with algebraic structures derived from modal logics. In the present paper, we develop a more abstract view and unify the two approaches. We show that dualities, or more generally dual adjunctions, between categories can be lifted to dual adjunctions between categories (...) of coalgebras and algebras, and from there to automata with initial as well as final states. As in the Stone-duality approach, algebras are essentially logics for reasoning about the automata. By exploiting the ability to pass between these categories, we show that one can minimize the corresponding automata. We give an abstract minimisation algorithm that has several instances, including the celebrated Brzozowski minimisation algorithm. We further develop three examples that have been treated in previous works: deterministic Kripke frames based on a Stone-type duality, weighted automata based on the self-duality of semimodules, and topological automata based on Gelfand duality. As a new example, we develop alternating automata based on the discrete duality between sets and complete atomic Boolean algebras. (shrink)

Films typically provide an experience that is very much like the experience of ordinary motion. It is for this reason that they are commonly known as moving pictures or, slightly more broadly, moving images. Our focus in this chapter is on making sense of that experience. We begin our chapter by exploring the centrality of the experience of movement to film. We turn then to various explanations of that experience. Perhaps film images are transparent and allow us to indirectly see (...) the movement of the objects they depict. Or perhaps certain theories of depiction can make sense of the experience of motion in cinema. In the final section, we address a range of ontological issues raised by the question of cinematic movement. Is the motion of images real movement or merely illusory? What is a cinematic image?

Despite his longstanding silence regarding Marx’s Capital, I wish here to argue that Badiou has in fact, in the three volumes of Being and Event, produced the materials for a contemporary logic of the capitalist social form. He has done so, however, in the form of an arsenal of abstract concepts that have yet to be precisely measured against Marx’s critical and formal reproduction of capitalism, the systematic exposition of which consumes the three volumes of Capital. I first argue that (...) Badiou’s general disinterest in the logic of capitalism and Marx’s Capital specifically takes on a strongly symptomatic, spectral presence in the 1994-1995 seminar Lacan: Anti-philosophy 3. Secondly, while it is true that Badiou’s Logics of Worlds never discusses the logic of appearance that governs all capitalist things, it is possible nonetheless to read Logics as an abstract translation and formalisation of Marx’s Capital. In this view, Capital should quite simply be read as a systematic demonstration of the logic of what Marx calls the capitalist social form, which is to say, in Badiou’s jargon, the logic or science of the appearance of things in the capitalist world. In a sense, then, this means nothing more, though nothing less, than subjecting the Logics of Worlds to a Marxian torsion: in order to demonstrate that which Badiou has neglected, Marx has in fact already accomplished, i.e. the systematic, synthetic demonstration of the necessary forms of the appearance of commodities in the capitalist social form.

The modeling of black holes is an important desideratum for any quantum theory of gravity. Not only is a classical black hole metric sought, but also agreement with the laws of black hole thermodynamics. In this paper, we describe how these goals are achieved in string theory. We review black hole thermodynamics, and then explicate the general stringy derivation of classical spacetimes, the construction of a simple black hole solution, and the derivation of its entropy. With that in hand, we (...) address some important philosophical and conceptual questions: the confirmatory value of the derivation, the bearing of the model on recent discussions of the so-called ‘information paradox’, and the implications of the model for the nature of space.

The latter part of the twentieth century saw the Chinese economy moving towards a socialist market economy rather than a planned system. Despite growing interest in Chinese business ethics, little work has examined ethical issues concerning the Chinese sales force. This study draws from existing work on Chinese and Western business and sales ethics to develop hypotheses regarding the perceptions of unethical selling behaviour of modern Chinese salespeople. A survey of Chinese sales executives is conducted and statistically analysed. Results are (...) compared with those reported in previous US-based research with regard to differences in perceptions of unethical selling behaviour. The results indicate that contemporary Chinese salespeople were more favourably disposed than expected towards unethical selling behaviour, and also more favourably disposed than previously studied US salespeople. Younger Chinese salespeople evaluated unethical behaviours more favourably than older ones. The results are discussed, along with implications for theory, practice and future work. (shrink)

This article describes and analyses the social network of key actors involved in the `inner circle' of the early UK punk movement in London. It is argued that the network and its structural properties are important if we wish to explain both the emergence of the movement and certain key conflicts within it. The article is empirically based and utilizes the methods of formal social network analysis. A further argument of the paper is that the concept of networks and these (...) formal methods for analysing them are both important for a sociological analysis of culture and cultural movements in particular.

As Pooley (2001) explains, the challenge of giving a relational account of orientability (and topology more generally) is not an easy one. This paper criticizes Pooley's and other proposals, raises a range of problems for the project, and then proposes a novel way for the relationist to understand not only topology, but also the geometry of space. This proposal is the `regularity account' since it claims that geometry and topology supervene on the regular ways in which relations evolve.

Escalation of commitment causes people to continue a failing course of action. We study the role of construal level in such escalation of commitment. Consistent with the widely held view of construal level as a primed effect, we employed a commonly used prime for manipulating this construct in a laboratory experiment. Our findings revealed that the prime failed to produce statistically significant differences in construal level, which was measured using the Behavior Identification Form. Furthermore, there was no effect of the (...) prime on escalation of commitment, or on constructs that have previously been linked to construal level such as the perceived importance of feasibility considerations relative to desirability considerations, and the number of pros and cons that subjects can think of.Interestingly, however, subjects’ actual construal level scores on the BIF were found to significantly affect escalation. Specifically, our findings show that people with a low construal level are less willing to continue a failing project. This relation is mediated by the perceived importance of the feasibility of the project relative to its desirability. For people with a low construal level, the perceived importance of feasibility relative to desirability is higher, which in turn makes escalation of commitment less likely.Our findings are consistent with prior research suggesting that priming construal level may not always be effective. Thus, while construal level has typically been regarded as a state-like variable that can be primed, in this study, we show that construal level may also be considered as a trait. (shrink)

This essay reviews two recent books—Marion Laboure and Nicolas Deffrennes's Democratizing Finance and Eswar S. Prasad's The Future of Money—on financial technology (fintech) and the future of money. Both books present overviews of recent developments in fintech and assess the prospects of technological change to deliver a more accessible, equitable financial system—described in both cases as the “democratization of finance.” I raise two key concerns about the limits of the “democratization” implied here. First, the vision of democratized finance implicit in (...) both books rests on claims about widening access to financial services for individuals, households, and businesses. This contrasts with more substantive visions of democratized finance that entail the exercise of accountable, deliberative decision-making on monetary and financial questions. Second, “fintech democracy” rests on a very thin account of how finance might be democratized, stressing exogenous technological change, with little consideration of relations of power, institutional reforms, or mobilization. Both books provide eloquent and comprehensive overviews of emerging fintech debates, but in so doing ultimately reveal important limitations to achieving financial democracy through fintech.

Since the collapse of the 'received view' consensus in the late 1960s, the question of scientific realism has been a major preoccupation of philosophers of science. This paper sketches the history of this debate, which grew from developments in the philosophy of language, but eventually took on an autonomous existence. More recently, the debate has tended towards more 'local' considerations of particular scientific episodes as a way of getting purchase on the issues. The paper reviews two such approaches, Fine's and (...) Hacking's, describing their positions, their prospects, and how they are related. Finally, the paper suggests that local philosophies of science offer a way for our discipline to engage more fruitfully with the public and the scientific community. (shrink)
