If one wishes to understand what money is, to whom should one turn as the most reliable source of knowledge? Of course, economists propose themselves as the experts on the matter. Who, if not those who study in- terest rates, prices and exchanges could know more about the nature of money? Yet, with a few exceptions, those philosophers in the burgeoning field of social ontology who ask ‘what is money?’ (or, for that matter, ‘what is a marriage?, ‘what is ownership?’, (...) ‘what is a cocktail party?’, etc.) tend to ignore what past and present social scientists maintain on these issues. John Searle comes to mind as having such an insulated approach. Since The Construction of Social Reality, Searle has repeatedly claimed to have found no adequate definition of institutions on the part of those scholars who are the most concerned with them. Understanding Institutions leaves a different impression about the state of the art. In this elegant book, Francesco Guala shows that social scien- tists, economists in particular, can actually be trusted in how they under- stand the notions which they apply. Guala finds in game theory the relevant conceptual framework in which to explore the nature of institutions. Fol- lowing David Hume, David Lewis, and Edna Ullmann-Margalit, he defends a view, termed the rule-in-equilibrium account, which conceives institutions as solutions to coordination problems. For example, to determine what a marriage is, we must look at the range of coordination dilemmas which married couples have resolved: Who cooks? Who picks up the children f rom school? Who washes the dishes? etc. Likewise, the institution of own- ership states who will make use of what? The highway code indicates which side of the road to drive on. Cocktail parties? I gather they specify when to entertain and who to bond with. (shrink)

In his influential book 'Making Things Happen' and in other places, Jim Woodward has noted some affinities between his own account of causation and that of Menzies and Price, but argued that the latter view is implausibly ‘subjective’. In this piece I discuss Woodward’s criticisms. I argue that the Menzies and Price view is not as different from Woodward’s own account as he believes, and that in so far as it is different, it has some advantages whose importance (...) Woodward misses; but also that the Menzies and Price view lacks some elements whose importance Woodward rightly stresses. When properly characterized, however, the ‘subjectivity’ survives unscathed.

Literature in epistemology tends to suppose that there are three main types of understanding – propositional, atomistic, and objectual. By showing that all apparent instances of propositional understanding can be more plausibly explained as featuring one of several other epistemic states, this paper argues that talk of propositional understanding is unhelpful and misleading. The upshot is that epistemologists can do without the notion of propositional understanding.

In this article, we redefine classical notions of theory reduction in such a way that model-theoretic preferential semantics becomes part of a realist depiction of this aspect of science. We offer a model-theoretic reconstruction of science in which theory succession or reduction is often better - or at a finer level of analysis - interpreted as the result of model succession or reduction. This analysis leads to 'defeasible reduction', defined as follows: The conjunction of the assumptions of a reducing theory (...) T with the definitions translating the vocabulary of a reduced theory T' to the vocabulary of T, defeasibly entails the assumptions of reduced T'. This relation of defeasible reduction offers, in the context of additional knowledge becoming available, articulation of a more flexible kind of reduction in theory development than in the classical case. Also, defeasible reduction is shown to solve the problems of entailment that classical homogeneous reduction encounters. Reduction in the defeasible sense is a practical device for studying the processes of science, since it is about highlighting different aspects of the same theory at different times of application, rather than about naive dreams concerning a metaphysical unity of science.

Are the distinctions between past, present and future, and the apparent ‘passage’ of time, features of the world in itself, or manifestations of the human perspective? Questions of this kind have been at the heart of metaphysics of time since antiquity. The latter view has much in common with pragmatism, though few in these debates are aware of that connection, and few of the view’s proponents think of themselves as pragmatists. For their part, pragmatists are often unaware of this congenial (...) application of their methodology; some associate pragmatism with the other side of the old debate in the metaphysics of time. In my view, this link between time and pragmatism only scratches the surface of the deep two-way dependencies between these two topics. The human temporal perspective turns out to be deeply implicated not merely in our temporal notions themselves, but in many other conceptual categories – arguably, in fact, in all of them, and in the nature of language and thought. In this way, reflection on our own temporal character vindicates James’ famous slogan for global pragmatism: ‘The trail of the human serpent is thus over everything.’. (shrink)

Political theory as a discipline has long been skeptical of computational methods. In this paper, I argue that it is time for theory to make a perspectival shift on these methods. Specifically, we should consider integrating recently developed generative large language models like GPT-4 as tools to support our creative work as theorists. Ultimately, I suggest that political theorists should embrace this technology as a method of supporting our capacity for creativity—but that we should do so in a way that (...) is mindful of the content and value of theorizing, the technical constraints of the models, and the ethical questions that the technology raises.

Scientists, philosophers, and policymakers disagree about how to define microaggression. Here, we offer a taxonomy of existing definitions, clustering around (a) the psychological motives of perpetrators, (b) the experience of victims, and (c) the functional role of microaggression in oppressive social structures. We consider conceptual and epistemic challenges to each and suggest that progress may come from developing novel hybrid accounts of microaggression, combining empirically tractable features with sensitivity to the testimony of victims.

I am arguing that it is only by concentrating on the role of models in theory construction, interpretation and change, that one can study the progress of science sensibly. I define the level at which these models operate as a level above the purely empirical (consisting of various systems in reality) but also indeed below that of the fundamental formal theories (expressed linguistically). The essentially multi-interpretability of the theory at the general, abstract linguistic level, implies that it can potentially make (...) claims about systems in reality, other than the particular one which originally induced it. Any so-called correspondence relation between (systems in) reality and the entities and relations in some scientific theory, thus consists of two jumps or interpretations: from the theory (linguistic level) to some model of it (constructural level); and from there to some system in reality. Clearly then the level of fundamental theories cannot be ignored la Nancy Cartwright - in studying the relations between a theory and reality, because the particular features of the theory (the various systems in reality onto which the theory can be mapped) cannot be studied without the underlying knowledge that these systems have one common feature, namely that each of them is the range (or other pole) of a mapping of a context-specific model of the theory - which in itself, is a mapping, or more specifically, an interpretation of the theory. I am also claiming that the nature of these levels and the relations between them necessitate an epistemological rather than an ontological notion of truth criteria, and a referential rather than a representational link between science and reality.

In this article, we aim to map out the complexities which characterise debates about the ethics of vaccine distribution, particularly those surrounding the distribution of the COVID-19 vaccine. In doing so, we distinguish three general principles which might be used to distribute goods and two ambiguities in how one might wish to spell them out. We then argue that we can understand actual debates around the COVID-19 vaccine – including those over prioritising vaccinating the most vulnerable – as reflecting disagreements (...) over these principles. Finally, we shift our attention away from traditional discussions of distributive justice, highlighting the importance of concerns about risk imposition, special duties, and social roles in explaining debates over the COVID-19 vaccine. We conclude that the normative complexity this article highlights deepens the need for decision-making bodies to be sensitive to public input. (shrink)

This essay is my contribution to a celebratory volume for Mr Peter Ho, former head of Singapore's Civil Service, from whom I learned the phrase ‘black elephant’. I reflect on four elephants among my own interests: in other words, big things (in my estimation), in clear sight but invisible to many eyes. They are: (i) retrocausality in quantum theory; (ii) child conscription and the monarchy; (iii) AI risk; and (iv) cold fusion. As I say in the piece, my little herd (...) is big enough to make some comparisons – though this may be the only occasion on which they congregate in the same room. (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)

At first glance, hate speech and microaggressions seem to have little overlap beyond being communicated verbally or in written form. Hate speech seems clearly macro-aggressive: an intentional, obviously harmful act lacking the ambiguity (and plausible deniability) of microaggressions. If we look back at historical discussions of hate speech, however, many of these assumed differences turn out to be points of similarity. The harmfulness of hate speech only became widely acknowledged after a concerted effort by critical race theorists, feminists, and other (...) activists. Before the 1990s, slurs were widely considered socially acceptable behavior: mere jokes that weren’t intended to be harmful. Authors like Richard Delgado, Mari Matsuda, and Charles Lawrence pushed back against this dismissal. In this chapter, I show that their arguments for the serious harmfulness of hate speech prefigure and provide support for current debates about the serious harmfulness of microaggressions. Exploring resonances with the 1980s hate speech debate will allow us to explain why microaggressions fall below the cutoff for legal liability but remain apt targets for moral blame. (shrink)

This paper discusses the relation between Crispin Wright’s alethic pluralism and my global expressivism. I argue that on many topics Wright’s own view counts as expressivism in my sense, but that truth itself is a striking exception. Unlike me, Wright never seems to countenance an expressivist account of truth, though the materials needed are available to him in his approaches to other topics.

Microaggressions are seemingly negligible slights that can cause significant damage to frequently targeted members of marginalized groups. Recently, Scott O. Lilienfeld challenged a key platform of the microaggression research project: what’s aggressive about microaggressions? To answer this challenge, Derald Wing Sue, the psychologist who has spearheaded the research on microaggressions, needs to theorize a spectrum of aggression that ranges from intentional assault to unintentional microaggressions. I suggest turning to Bonnie Mann’s “Creepers, Flirts, Heroes and Allies” for inspiration. Building from Mann’s (...) richer theoretical framework will allow Sue to answer Lilienfeld’s objection and defend the legitimacy of the concept, ‘microaggression’. (shrink)

In his editorial, Nir Eyal argues that a nudge can exploit our propensity to feel shame in order to steer us toward certain choices. We object that shame is a cost and therefore cannot figure in the apparatus of a nudge.

Epistemic paternalism is the thesis that a paternalistic interference with an individual's inquiry is justified when it is likely to bring about an epistemic improvement in her. In this article I claim that in order to motivate epistemic paternalism we must first account for the value of epistemic improvements. I propose that the epistemic paternalist has two options: either epistemic improvements are valuable because they contribute to wellbeing, or they are epistemically valuable. I will argue that these options constitute the (...) foundations of a dilemma: either epistemic paternalism collapses into general paternalism, or a distinctive project of justified epistemic paternalism is implausible.

A number of philosophers have argued that if you care about how much goodness your actions generate, or how good the state-of-affairs you actions bring about are, then your attention should be directed towards the very far future. But many don’t care about how much goodness their actions generate, nor do they care about things like “states-of-affairs”. Amongst a multitude of things, many people care about how their actions impact individuals. And they also care about the sorts of justifications they (...) are able to offer for those actions. One moral theory which captures this moral viewpoint is contractualism. In this chapter, I argue that contractualism is, in large part, incompatible with longtermism – the view that, in many contexts, we ought to do that which will most improve the prospects of future people. I then discuss what advice, if any at all, contractualism can offer to the longtermist. (shrink)

In this paper, I focus on the representations of Black women in contrast to Black men found within Frantz Fanon’s philosophical work Black Skin, White Masks. I propose that while Fanon’s racial dialectical work is very significant, he often lacks acknowledgement of the multidimensionality of the Black woman’s lived experience specifically. Drawing on the theory of intersectionality, coined by Kimberlé Crenshaw, I argue that Fanon does not recognize the different layers of oppression operating in Black women’s lives to the degree (...) that he fails to include them within his framework of both liberation and resistance from racial oppression.

A model-theoretic realist account of science places linguistic systems and their corresponding non-linguistic structures at different stages or different levels of abstraction of the scientific process. Apart from the obvious problem of underdetermination of theories by data, philosophers of science are also faced with the inverse (and very real) problem of overdetermination of theories by their empirical models, which is what this article will focus on. I acknowledge the contingency of the factors determining the nature – and choice – of (...) a certain model at a certain time, but in my terms, this is a matter about which we can talk and whose structure we can formalise. In this article a mechanism for tracing "empirical choices" and their particularized observational-theoretical entanglements will be offered in the form of Yoav Shoham's version of non-monotonic logic. Such an analysis of the structure of scientific theories may clarify the motivations underlying choices in favor of certain empirical models (and not others) in a way that shows that "disentangling" theoretical and observation terms is more deeply model-specific than theory-specific. This kind of analysis offers a method for getting an articulable grip on the overdetermination of theories by their models – implied by empirical equivalence – which Kuipers' structuralist analysis of the structure of theories does not offer.

This is an unpublished piece from July 1998. It discusses the use of semantic notions such as reference in the Canberra Plan, the question whether this use creates a problematic circularity if the Canberra Plan is applied to the semantic notions themselves, and the relation of this question to Putnam’s model-theoretic argument. I used some of the ideas in later papers such as (Price 2004, 2009) and (Menzies & Price, 2009), but the bulk of discussion of the relation (...) of my concern to Putnam’s argument (and to responses to Putnam by others) never made it into print.

Although expert consensus states that critical thinking (CT) is essential to enquiry, it doesn’t necessarily follow that by practicing enquiry children are developing CT skills. Philosophy with children programmes around the world aim to develop CT dispositions and skills through a community of enquiry, and this study compared the impact of the explicit teaching of CT skills during an enquiry, to The Philosophy Foundation's philosophical enquiry (PhiE) method alone (which had no explicit teaching of CT skills). Philosophy with children is (...) also said to improve metacognitive (MC) skills but there is little research into this claim. Following observable problems with ensuring genuine metacognition was happening in PhiE sessions - on a reasonably strong understanding of what metacognition is – a method has been developed and trialed in this study to bring together, in mutual support, the development of critical thinking and metacognitive skills. Based on the work of Peter Worley and Ellen Fridland (KCL)The Philosophy Foundation ran an experimental study with King's College London in Autumn 2017 and Autumn 2018 to compare the impact of teaching CT skills and MC skills against classes that just have philosophical enquiry. The approach developed and used for the study employs the explicit teaching of some CT and MC skills within the context of a philosophical enquiry (as opposed to stand-alone teaching of these skills) and yields some positive findings both qualitative and quantitative. Both studies took place over one term (12 weeks) and a control and intervention group were used in each study. This report focuses on the second year of the study, with 220 ten and eleven-year-old children involved in eight classes across three state schools in South East London. Although there were limitations to the study the results indicate that the explicit teaching of these skills during a philosophical enquiry can help children use CT and MC skills more successfully than philosophical enquiry alone.

Many theorists have focused on Wittgenstein’s use of examples, but I argue that examples form only half of his method. Rather than continuing the disjointed style of his Cambridge lectures, Wittgenstein returns to the techniques he employed while teaching elementary school. Philosophical Investigations trains the reader as a math class trains a student—‘by means of examples and by exercises’ (§208). Its numbered passages, carefully arranged, provide a series of demonstrations and practice problems. I guide the reader through one such series, (...) demonstrating how the exercises build upon one another and give us ample opportunity to hone our problem-solving skills. Through careful practice, we learn to pass the test Wittgenstein poses when he claims that something is ‘easy to imagine’ (§19). Whereas other critics have viewed the Investigations as merely a diagnosis of our philosophical delusions, I claim that Wittgenstein also writes a prescription for our disease: Do your exercises.

This is a first tentative examination of the possibility of reinstating reduction as a valid candidate for presenting relations between mental and physical properties. Classical Nagelian reduction is undoubtedly contaminated in many ways, but here I investigate the possibility of adapting to problems concerning mental properties an alternative definition for theory reduction in philosophy of science. The definition I offer is formulated with the aid of non-monotonic logic, which I suspect might be a very interesting realm for testing notions concerning (...) localized mental-physical reduction. The reason for this is that non-monotonic reasoning by definition is about appeals made not only to explicit observations, but also to an implicit selection of background knowledge containing heuristic information. The flexibility of this definition and the fact that it is not absolute, i.e. that the relation of reduction may be retracted or allowed to shift without fuss, add at least an interesting alternative factor to current materialist debates.

In this inaugural lecture I offer, against the background of a discussion of knowledge representation and its tools, an overview of my research in the philosophy of science. I defend a relational model-theoretic realism as being the appropriate meta-stance most congruent with the model-theoretic view of science as a form of human engagement with the world. Making use of logics with preferential semantics within a model-theoretic paradigm, I give an account of science as process and product. I demonstrate the power (...) of the full-blown employment of this paradigm in the philosophy of science by discussing the main applications of model-theoretic realism to traditional problems in the philosophy of science. I discuss my views of the nature of logic and of its role in the philosophy of science today. I also specifically offer a brief discussion on the future of cognitive philosophy in South Africa. My conclusion is a general look at the nature of philosophical inquiry and its significance for philosophers today. South African Journal of Philosophy Vol. 25 (4) 2006: pp. 275-289. (shrink)

In this article I give an overview of some recent work in philosophy of science dedicated to analysing the scientific process in terms of (conceptual) mathematical models of theories and the various semantic relations between such models, scientific theories, and aspects of reality. In current philosophy of science, the most interesting questions centre around the ways in which writers distinguish between theories and the mathematical structures that interpret them and in which they are true, i.e. between scientific theories as linguistic (...) systems and their non-linguistic models. In philosophy of science literature there are two main approaches to the structure of scientific theories, the statement or syntactic approach -- advocated by Carnap, Hempel and Nagel -- and the non- statement or semantic approach --advocated, among others, by Suppes, the structuralists, Beth, Van Fraassen, Giere, Wojcicki. In conclusion, I briefly review some of the usual realist inspired questions about the possibility and character of relations between scientific theories and reality as implied by the various approaches I discuss in the course of the article. The models of a scientific theory should indeed be adequate to the phenomena, but if the theory is 'adequate' to (true in) its conceptual (mathematical) models as well, we have a model-theoretic realism that addresses the possible meaning and reference of 'theoretical entities' without relapsing into the metaphysics typical of the usual scientific realist approaches.

Advocates of longtermism point out that interventions which focus on improving the prospects of people in the very far future will, in expectation, bring about a significant amount of good. Indeed, in expectation, such long-term interventions bring about far more good than their short-term counterparts. As such, longtermists claim we have compelling moral reason to prefer long-term interventions. In this paper, I show that longtermism is in conflict with plausible deontic scepticism about aggregation. I do so by demonstrating that, from (...) both an ex-ante and ex-post perspective, longtermist interventions – and, in particular, those which aim to mitigate catastrophic risk – typically generate extremely weak claims of assistance from future people.

One way in which to address the intriguing relations between science and reality is to work via the models (mathematical structures) of formal scientific theories which are interpretations under which these theories turn out to be true. The so-called 'statement approach' to scientific theories -- characteristic for instance of Nagel, Carnap, and Hempel --depicts theories in terms of 'symbolic languages' and some set of 'correspondence rules' or 'definition principles'. The defenders of the oppositionist non-statement approach advocate an analysis where the (...) language in which the theory is formulated plays a much smaller role. They hold that foundational problems in the various sciences can in general be better addressed by focusing on the models these sciences employ than by reformulating the products of these sciences in some appropriate language. My model-theoretic realist account of science lies decidedly within the non-statement context, although I retain the notion of a theory as a deductively closed set of sentences (expressed in some appropriate language), in this paper I shall focus -- against the background of a model-theoretic account of science -- on the approach to the reality-science dichotomy offered by Nancy Cartwright and briefly comment on a few aspects of Roy Bhaskar's transcendental realism. I shall, in conclusion, show how a model-theoretic approach such as mine can combine the best of these two approaches. (shrink)

Recent discussions of cognitive enhancement often note that drugs and technologies that improve cognitive performance may do so at the risk of “cheapening” our resulting cognitive achievements Arguing about bioethics, Routledge, London, 2012; Harris in Bioethics 25:102–111, 2011). While there are several possible responses to this worry, we will highlight what we take to be one of the most promising—one which draws on a recent strand of thinking in social and virtue epistemology to construct an integrationist defence of cognitive enhancement.. (...) According to such a line, there is—despite initial appearances to the contrary—no genuine tension between using enhancements to attain our goals and achieving these goals in a valuable way provided the relevant enhancement is appropriately integrated into the agent’s cognitive architecture. In this paper, however, we show that the kind of integration recommended by such views will likely come at a high cost. More specifically, we highlight a dilemma for users of pharmacological cognitive enhancement: they can meet the conditions for cognitive integration at the significant risk of dangerous dependency, or remain free of such dependency while foregoing integration and the valuable achievements that such integration enables. After motivating and clarifying the import of this dilemma, we offer recommendations for how future cognitive enhancement research may offer potential routes for navigating past it. (shrink)

We argue that machine learning algorithms can inflict microaggressions on members of marginalized groups and that recognizing these harms as instances of microaggressions is key to effectively addressing the problem. The concept of microaggression is also illuminated by being studied in algorithmic contexts. We contribute to the microaggression literature by expanding the category of environmental microaggressions and highlighting the unique issues of moral responsibility that arise when we focus on this category. We theorize two kinds of algorithmic microaggression, stereotyping and (...) erasure microaggressions, and argue that corporations are responsible for the microaggressions their algorithms create. As a case study, we look at the problems faced by Google’s autocomplete prediction and at the insufficiency of their solutions. The case study of autocomplete demonstrates our core claim that microaggressions constitute a distinct form of algorithmic bias and that identifying them as such allows us to avoid seeming solutions that recreate the same kinds of harms. Google has a responsibility to make information freely available, without exposing users to degradation. To fulfill its duties to marginalized groups, Google must abandon the fiction of neutral prediction and instead embrace the liberatory power of suggestion. (shrink)

If the defenders of typical postmodern accounts of science (and their less extreme social-constructivist partners) are at one end of the scale in current philosophy of science, who shall we place at the other end? Old-style metaphysical realists? Neo-neo-positivists? ... Are the choices concerning realist issues as simple as being centered around either, on the one hand, whether it is the way reality is “constructed” in accordance with some contingent language game that determines scientific “truth”; or, on the other hand, (...) whether it is the way things are in an independent reality that makes our theories true or false? If, in terms of realism, “strong” implies “metaphysical” in the traditional sense, and “weak” implies “non-absolutist” or “non-unique”, what – if anything – could realism after Rorty's shattering of the mirror of nature still entail? In accordance with my position as a model-theoretic realist, I shall show in this article the relevance of the assumption of an independent reality for postmodern (philosophy of) science – against Lyotard's dismissal of the necessity of this assumption for science which he interprets as a non-privileged game among many others. I shall imply that science is neither the “child” of positivist philosophy who has outgrown her mother, freeing herself from metaphysics and epistemology, nor is science, at the other end of the scale, foundationless and up for grabs.

Ismael traces our sense that the past is fixed and the future open to what she calls ‘the practical arrow’ – ‘the sense that we can affect the future but not the past.’ In this piece I draw a sharper distinction than Ismael herself does between agents and mere observers, even self-referential observers; and I use it to argue that Ismael’s explanation of the practical arrow is incomplete. To explain our inability to affect the past we need to appeal to (...) our own temporal orientation as agents, and not merely to the ingredients from physics that allow us to predict the consequences of our actions.

Recent thinking within philosophy of mind about the ways cognition can extend has yet to be integrated with philosophical theories of emotion, which give cognition a central role. We carve out new ground at the intersection of these areas and, in doing so, defend what we call the extended emotion thesis: the claim that some emotions can extend beyond skin and skull to parts of the external world.

This is my Cambridge PhD thesis, written under the supervision of Hugh Mellor and Richard Healey, and examined by Mary Hesse and Simon Blackburn. It addresses what it takes to be the core of the problem of single case probability, namely, the interpretation of claims such as ‘It is probable that P’ (where the probabilistic component occurs as a sentential or propositional operator). I argue that claims of this form are not genuinely truth-apt, and that such operators modify the force, (...) rather than the sense, of sentences or propositions to which they attach. In contemporary terms, I thus defend a version of what Yalcin (2012) has called ‘credal expressivism’. Some of the core arguments were later published in the following papers: (i) ‘Does “Probably” modify sense?’, Australasian Journal of Philosophy 61(1983), 396–408 and (ii) 'Mellor, chance and the single case', British Journal for the Philosophy of Science 35(1984), 11-23. Other arguments, including an attempt at the Frege-Geach problem, form the basis of an unpublished piece 'The use of force in a theory of meaning' (1983), accessible at PhilPapers. (shrink)

There is a current debate about the grammar of intention: do I intend to φ, or that I φ? The equivalent question in Aristotle relates especially to choice. I argue that, in the context of practical reasoning, choice, as also wish, has as its object an act. I then explore the role that this plays within his account of the relation of thought to action. In particular, I discuss the relation of deliberation to the practical syllogism, and the thesis that (...) the conclusion of the second is an action. (shrink)

This is a review of Zalabardo's Pragmatist Semantics (OUP, 2023), forthcoming in Mind.

This piece was written as my Presidential Address at the Annual Conference of the Australasian Association of Philosophy, held at Melbourne University in July 1999. I discuss the view ‘that we can’t describe or theorise about the world from outside language.’ I call this idea ‘linguistic imprisonment’, and take it to be a platitude, although one that is interpreted very differently by different philosophers. In so far as language does depend on contingencies of our own ‘location’, how should we theorise (...) about such matters? I distinguish two approaches, called ‘backgrounding’ and ‘foregrounding’. Roughly, the latter seeks to incorporate the contingencies into the content of claims that depend on them, whereas the former treats them as use conditions. I argue that linguistic imprisonment implies that not everything can be foregrounded, and apply the framework to a then-recent objection to expressivism by Jackson and Pettit. (shrink)

I argue that anarchist ideas for organising human communities could be a useful practical resource for Christian ethics. I demonstrate this firstly by introducing the main theological ideas underlying Maximus the Confessor’s ethics, a theologian respected and important in a number of Christian denominations. I compare practical similarities in the way in which ‘love’ and ‘well-being’ are interpreted as the telos of Maximus and Peter Kropotkin’s ethics respectively. I further highlight these similarities by demonstrating them in action when it comes (...) attitudes towards property. I consequently suggest that there are enough similarities in practical aims, for Kropotkin’s ideas for human organising to be useful to Christian ethicists. (shrink)

While openmindedness is often cited as a paradigmatic example of an intellectual virtue, the connection between openmindedness and truth is tenuous. Several strategies for reconciling this tension are considered, and each is shown to fail; it is thus claimed that openmindedness, when intellectually virtuous, bears no interesting essential connection to truth. In the final section, the implication of this result is assessed in the wider context of debates about epistemic value.

Duncan Pritchard (2008, 2009, 2010, forthcoming) has argued for an elegant solution to what have been called the value problems for knowledge at the forefront of recent literature on epistemic value. As Pritchard sees it, these problems dissolve once it is recognized that that it is understanding-why, not knowledge, that bears the distinctive epistemic value often (mistakenly) attributed to knowledge. A key element of Pritchard’s revisionist argument is the claim that understanding-why always involves what he calls strong cognitive achievement—viz., cognitive (...) achievement that consists always in either (i) the overcoming of a significant obstacle or (ii) the exercise of a significant level of cognitive ability. After outlining Pritchard’s argument, we show (contra Pritchard) that understanding-why does not essentially involve strong cognitive achievement. Interestingly, in the cases in which understanding-why is distinctively valuable, it is (we argue) only because there is sufficiently rich objectual understanding in the background. If that’s right, then a plausible revisionist solution to the value problems must be sensitive to different kinds of understanding and what makes them valuable, respectively. (shrink)

In recent work Allan Gibbard claims to be both a local quasi-realist, in Blackburn’s sense, and a global expressivist. His local quasi-realism rests on an argument that for naturalistic discourse but not ethical discourse, the semantic relation of denotation and the causal relation of tracking can and should be identified; that denoting simply is tracking, for naturalistic vocabulary. I argue that Gibbard’s case for this conclusion is unconvincing, and poorly motivated by his own expressivist standards. I also argue that even (...) if it were successful, it is doubtful whether the resulting position would count as global expressivism, as Gibbard and I both use that term. (shrink)

Many areas of philosophy employ a distinction between factual and non-factual (descriptive/non-descriptive, cognitive/non-cognitive, etc) uses of language. This book examines the various ways in which this distinction is normally drawn, argues that all are unsatisfactory, and suggests that the search for a sharp distinction is misconceived. The book develops an alternative approach, based on a novel theory of the function and origins of the concept of truth. The central hypothesis is that the main role of the normative notion of truth (...) is to encourage speakers to argue, with long-run behavioural advantages. This offers a fresh perspective on many debates about realism in contemporary philosophy.

This article considers the role of emotion in John Henry Newman's Grammar of Assent by distinguishing five different ways (or ‘models’) in which the emotions play a positive epistemic role in relation to cognition. The most important of these, the Cognitive-Emotion Model, offers a new account of Newman's crucial idea of real assent, one that stresses the primary role of the emotions in real assent rather than imagination. This model helps to explain the nature of real assent by highlighting Newman's (...) portrayal of an emotional way of knowing an object that is personal or individual, incommunicable, vivid, and motive. In this study of the relations between emotion and cognition I hope to highlight unexplored aspects of the nature of real assent and the importance of the role of emotion in it and hope to show how Newman's epistemology offers a rich framework for exploring the positive epistemic contributions of the emotions. -/- .

In this paper, we report the results from an experimental reproductive ethics study exploring questions about reproduction and parenthood. The main finding in our study is that, while we may assume that everyone understands these concepts and their relationship in the same way, this assumption may be unwarranted. For example, we may assume that if ‘x is y’s father’, it follows that ‘y is x’s child’. However, the participants in our study did not necessarily agree that it does follow. This (...) means, at the very least, that we need to make sure all parties in a debate have the same relationships in mind when talking about reproduction and parenthood. Moreover, it gives us reason to explore more carefully the conditions which support or undermine the connections between these concepts. This cannot come from purely theoretical reasoning, nor from empirical research alone, but from the alliance between the two. (shrink)

Causalists and Evidentialists can agree about the right course of action in an (apparent) Newcomb problem, if the causal facts are not as initially they seem. If declining $1,000 causes the Predictor to have placed $1m in the opaque box, CDT agrees with EDT that one-boxing is rational. This creates a difficulty for Causalists. We explain the problem with reference to Dummett's work on backward causation and Lewis's on chance and crystal balls. We show that the possibility that the causal (...) facts might be properly judged to be non-standard in Newcomb problems leads to a dilemma for Causalism. One horn embraces a subjectivist understanding of causation, in a sense analogous to Lewis's own subjectivist conception of objective chance. In this case the analogy with chance reveals a terminological choice point, such that either (i) CDT is completely reconciled with EDT, or (ii) EDT takes precedence in the cases in which the two theories give different recommendations. The other horn of the dilemma rejects subjectivism, but now the analogy with chance suggests that it is simply mysterious why causation so construed should constrain rational action. (shrink)

Hume maintained that, philosophically speaking, there is no difference between exiting a room out of the first-floor window and using the door. Nevertheless, Hume’s reason and common sense prevailed over his scepticism and he advocated that we should always use the door. However, we are currently living in a world that is more seriously committed to the Humean philosophy of empiricism than he was himself and thus the potential to act inappropriately is an ever-present potential. In this paper, I explore (...) how Hume’s two versions of causality have detrimentally affected our ability both to arrive at and to use research to improve human well-being. I illustrate my argument with an example of what I think is an incorrect yet supposedly scientifically sound assumption: that absenteeism causes poor school attainment. Instead I make the interdisciplinary argument that absenteeism is better understood as an aggravating symptom of a number of other causes of poor attainment, such as poverty and individual psychological factors. I suggest that an instrumental, punitive policy against parents whose children tend to be absent from school may be ineffectual or even counterproductive if the objective is to improve the well-being of those children. To support my argument, I introduce the critical realist idea of transfactuality. Using the example of research into moon rocks, I show how mainstream science uses transfactuality despite its empiricist aversion to it. I also suggest that it is our honesty, integrity, and stoicism that lead us to the extreme overthrow of reason and common sense that we see today in many of the UK’s social policies; an overthrow that Hume himself did not achieve. Metaphorically speaking, British professionals, stoically and honestly believing in the ability of their trusted research correlations to guide their action, are exiting out of the first-floor window rather than using the door. This is a significant barrier to our ability to devise and implement social policy. (shrink)

This piece was written circa 1982–83, drawing in part on material from my PhD thesis (The Problem of the Single Case, Cambridge, 1981). In the thesis I proposed what would now be called an expressivist account of judgements of the form ‘It is probable that p’. One chapter, on which this paper builds, tried to defend the view against the Frege-Geach argument. This piece earned a revise and resubmit from Philosophical Review, but was never resubmitted. Parts of it made their (...) way into my ‘Semantic Minimalism and the Frege Point’, in Tsohatzidis, S.L.(ed.), Foundations of Speech Act Theory: Philosophical and Linguistic Perspectives, Routledge, 1994, pp. 132–55 (reprinted in Naturalism without Mirrors, Oxford, 2011, ch. 3) – though that paper favours a different approach to the Frege-Geach argument, leaning more heavily on semantic minimalism. I’m putting this piece online to facilitate self-citation. (shrink)
