This paper is an exposition and evaluation of the Agustín Rayo's views about the epistemology and metaphysics of mathematics, as they are presented in his book The Construction of Logical Space.

Overview of the definition of art and its relationship to definitions of the individual art forms, with an eye to clarifying the issues separating dominant institutionalist and skeptical positions from non-skeptical, non-institutional ones. Section 2 indicates some of the key philosophical issues which intersect in discussions of the definition of art, and singles out some important areas of broad agreement and disagreement. Section 3 critically reviews some influential standard versions of institutionalism, and some more recent variations on them. Section 4 (...) discusses some recent reductionist approaches to definitional questions, which advocate a shift of philosophical focus from the macro- to the micro-level —from art to the individual art forms. Section 5 outlines an alternative, non-institutionalist and non-reductionist approach to definitional questions. (shrink)

Is it possible for an individual that has gone out of being to come back into being again? The English Aristotelian, Thomas White, argued that it is not. Thomas Hobbes disagreed, and used the case of the Ship of Theseus to argue that individuals that have gone out of being may come back into being again. This paper provides the first systematic account of their arguments. It is doubtful that Hobbes has a consistent case against White. Still his (...) criticism may have prompted White to clarify his views on identity over time in his later work. (shrink)

Theories of free will are often measured against how well they capture everyday intuitions about free will. But what are these everyday intuitions, and what theoretical commitments do they express? Empirical methods have delivered mixed messages. In response, some free will theorists have developed error theories to undermine the credentials of countervailing intuitions. These efforts are predicated on the idea that people might misunderstand determinism in any of several ways. This paper sheds light on the comprehension problem. We first discuss (...) recent efforts to explain systematic errors in how people interpret determinism. Then, we present the alarming results of two new preregistered studies exploring three types of comprehension failure: (a) epiphenomenal bypassing, (b) fatalistic bypassing, and (c) indeterministic intrusion. Our findings suggest that misunderstanding runs deeper than others have supposed. This casts doubt on existing models of commonsense thinking about free will. Unless and until researchers properly control for the kinds of misunderstandings we identify, research on free will intuitions cannot shed light on whether ordinary thinking reflects commitments to compatibilism or incompatibilism.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over (...) and above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

According to the so-called Classical Theory, concepts are mentally represented by individually necessary and jointly sufficient application conditions. One of the principal empirical objections against this view stems from evidence that people judge some instances of a concept to be more typical than others. In this paper we present and discuss four empirical studies that investigate the extent to which this ‘typicality effect’ holds for the concept of basic needs. Through multiple operationalizations of typicality, our studies yielded evidence for a (...) strong effect of this kind: Participants tended to recall the same core examples of the concept in a free-listing task. They judged some basic needs to be more typical than others. The items that were judged to be more typical were listed more frequently in the free-listing task. These items were listed earlier on in the free-listing task. Typical basic needs, as well as non needs, were classified faster than atypical basic needs in a reaction time study. These findings suggest that the concept of basic needs may have a non-classical structure. If so, the quest for a simple and robust intensional analysis of the concept may be futile. (shrink)

Andreas Schmidt and Neil Levy have recently defended nudging against the objection that nudges fail to treat nudgees as rational agents. Schmidt rejects two theses that have been taken to support the objection: that nudges harness irrational processes in the nudgee, and that they subvert the nudgee’s rationality. Levy rejects a third thesis that may support the objection: that nudges fail to give reasons. I argue that these defences can be extrapolated from nudges to some nonconsensual neurointerventions; if Schmidt’s and (...) Levy’s defences succeed, then some nonconsensual neurointerventions neither harness irrationality, nor subvert rationality, nor fail to give reasons. This, I claim, poses a challenge both to opponents of nonconsensual neurointerventions, and to defenders of nudging. (shrink)

Some philosophers believe that when epistemic peers disagree, each has an obligation to accord the other's assessment the same weight as her own. I first make the antecedent of this Equal-Weight View more precise, and then I motivate the View by describing cases in which it gives the intuitively correct verdict. Next I introduce some apparent counterexamples – cases of apparent peer disagreement in which, intuitively, one should not give equal weight to the other party's assessment. To defuse these apparent (...) counterexamples, an advocate of the View might try to explain how they are not genuine cases of peer disagreement. I examine David Christensen's and Adam Elga's explanations and find them wanting. I then offer a novel explanation, which turns on a distinction between knowledge from reports and knowledge from direct acquaintance. Finally, I extend my explanation to provide a handy and satisfying response to the charge of self-defeat. (shrink)

This paper accomplishes two goals. First, I present a distinct interpretation of the inception of the phenomenology of feelings. I show that Husserl’s first substantial discussion of intentional and non-intentional feelings is not from his 1901 Logical Investigations, but rather his 1893 manuscript, “Notes towards a Theory of Attention and Interest”. Husserl there describes intentional feelings as active and non-intentional feelings as passive. Second, I show that Husserl presents a somewhat unique account of feelings in “Notes”, which is partly different (...) from his later theories of feelings found in Lectures on Ethics and Value Theory and Studies Concerning the Structures of Consciousness. In contrast to those mature writings, in “Notes”, Husserl describes intentional feelings while avoiding cognitivism and he analyses non-intentional feelings without employing the content-apprehension schema. On this basis, I argue that “Notes” is an important untapped resource for constructing original phenomenologies of feelings. (shrink)

The young Edmund Husserl stressed that the success of his philosophy hinged upon his ability to determine the subject and the predicate of impersonal propositions and their expressions, such as ‘It is raining’. This essay accordingly investigates the tenability of Husserl’s early thought, by executing the first study of his analysis of impersonal propositions from the late 1890s. This examination reshapes our understanding of the inception of phenomenology in two ways. First, Husserl pinpoints the subject by outlining why impersonal expressions (...) are employed during communication. This contravenes interpretations of the early Husserl as uninterested in intersubjectivity. Second, by studying how Husserl determines the predicate by investigating existential propositions, I show that Husserl, in the late 1890s, came to his final view on the concept of being. (shrink)

Vagueness has gotten some attention in aesthetics, but deserves more. Vagueness is universally acknowledged to be ubiquitous. It has played a substantive role in some recent writing on the definition of art. It has figured importantly in analyses of the concept of literature, and (in connection with a thought experiment of Arthur Danto’s), of the ontology of art. Vagueness was a locus of contention in a debate between Alan Goldman and Eddy Zemach about the reality of aesthetic properties. This paper’s (...) aim is to advance that debate, by focusing on the relevance of vagueness to the familiar argument that moves from premises about aesthetic disagreement to the conclusion that aesthetic properties are not real. In what follows, it is argued that, vis-á-vis aesthetic disagreement, the vagueness of aesthetic properties can do important theoretical work for aesthetic realism. (shrink)

Intuitively, many people seem to hold that engaging in acts of virtual murder in videogames is morally permissible, whereas engaging in acts of virtual child molestation is morally impermissible. The Gamer’s Dilemma (Luck in Ethics Inf Technol 11:31–36, 2009) challenges these intuitions by arguing that it is unclear whether there is a morally relevant difference between these two types of virtual actions. There are two main responses in the literature to this dilemma. First, attempts to resolve the dilemma by defending (...) an account of the relevant moral differences between virtual murder and virtual child molestation. Second, attempts to dissolve the dilemma by undermining the intuitions that ground it. In this paper, we argue that a narrow version of the Gamer’s Dilemma seems to survive attempts to resolve or dissolve it away entirely, since neither approach seems to be able to solve the dilemma for all cases. We thus provide a contextually sensitive version of the dilemma that more accurately tracks onto the intuitions of gamers. However, we also argue that the intuitions that ground the narrow version of the Dilemma may not have a moral foundation, and we put forward alternative non-moral normative foundations that seem to better account for the remaining intuitive difference between the two types of virtual actions. We also respond to proposed solutions to the Gamer’s Dilemma in novel ways and set out areas for future empirical work in this area. (shrink)

We discuss abstraction principles in the context of modal and temporal logic. It is argued that abstractionism conflicts with both serious presentism and serious actualism.

The first aim of this paper is to prove a topological completeness theorem for a weak version of Stalnaker’s logic KB of knowledge and belief. The weak version of KB is characterized by the assumption that the axioms and rules of KB have to be satisfied with the exception of the axiom (NI) of negative introspection. The proof of a topological completeness theorem for weak KB is based on the fact that nuclei (as defined in the framework of point-free topology) (...) give rise to a profusion of topological belief operators that are compatible with the familiar topological knowledge operator. Thereby a canonical topological model for weak KB can be constructed. For this canonical model a truth lemma for the K and B holds such that a completeness theorem for KB can be proved in the familiar way. The second aim of this paper is to show that the topological interpretation of knowledge K comes along with a complete Heyting algebra of belief operators B that all fit the knowledge operator K in the sense that the pairs (K, B) satisfy all axioms of weak KB. This amounts to a pluralistic relation between knowledge and belief: Knowledge does not fully determine belief, rather it designs a conceptual space for belief operators where different (competing) belief operators coexist.

Typically, nudging is a technique for steering the choices of people without giving reasons or using enforcement. In benevolent cases, it is used when people are insufficiently responsive to reason. The nudger triggers automatic cognitive mechanisms – sometimes even biases – in smart ways in order to push irrational people in the right direction. Interestingly, this technique can also be applied to doxastic attitudes. Someone who is doxastically unresponsive to evidence can be nudged into forming true beliefs or doxastic attitudes (...) that are propositionally justified. When doxastic nudging uses non-rational mechanisms, the worry is that nudging cannot result in justified beliefs or knowledge, as the resulting doxastic attitudes lack the right kind of basis. In this paper, I will argue that given the right background views about knowledge, justified beliefs and the relevant processes, epistemic nudging is possible even in these cases. That is, all kinds of nudging can – in appropriate circumstances – produce justified beliefs or knowledge in the nudgee. (shrink)

The application of machine-learning technologies to medical practice promises to enhance the capabilities of healthcare professionals in the assessment, diagnosis, and treatment, of medical conditions. However, there is growing concern that algorithmic bias may perpetuate or exacerbate existing health inequalities. Hence, it matters that we make precise the different respects in which algorithmic bias can arise in medicine, and also make clear the normative relevance of these different kinds of algorithmic bias for broader questions about justice and fairness in healthcare. (...) In this paper, we provide the building blocks for an account of algorithmic bias and its normative relevance in medicine. (shrink)

This paper challenges the widely held view that ‘good for’, ‘well-being’, and related terms express a distinctive evaluative concept of central importance for ethics and separate from ‘simply good’ as used by G. E. Moore and others. More specifically, it argues that there's no philosophically useful good-for or well-being concept that's neither merely descriptive in the sense of naturalistic nor reducible to ‘simply good’. The paper distinguishes two interpretations of the common claim that the value ‘good for’ expresses is distinctively (...) ‘subject-relative’. One concerns the ground of this value, or the properties that make something good for you; it says these must involve some relation to you. The other concerns the resulting value itself, or what supervenes on this ground; it says that too involves a relation. Neither interpretation, the paper argues, yields a significantly distinct evaluative concept. The ethically fundamental evaluative concept is just ‘simply good’. (shrink)

"Meritocracy" has historically been understood in two ways. The first is as an approach to governance. On this understanding, we seek to put meritorious (somehow defined) people into public office to the benefit of society. This understanding has its roots in Confucius, its scope is political offices, and its justification is consequentialist. The second understanding of "meritocracy" is as a theory of justice. We distribute in accordance with merit in order to give people the things that they deserve, as justice (...) demands. This understanding has its roots in Aristotle, its scope is social goods broadly, and its justification is deontological. In this article, I discuss the differences--especially the conceptual differences--between these two, prima facie distinct, meritocratic traditions. I also argue that despite their differences Eastern Meritocracy and Western Meritocracy are harmonious. In Section I of the article I introduce the two meritocratic traditions through, in part, a highly abbreviated history of talk about "merit" and "meritocracy" in Chinese and Western philosophy. In Section II, I discuss a number of conceptual issues and partition meritocratic theories in accordance with their scopes and normative justifications. I also discuss two scenarios. In one scenario, Eastern Meritocracy appears to deliver the right result and Western Meritocracy, the wrong result. In the other scenario, vice versa. Finally, in Section III, I argue that Eastern Meritocracy and Western Meritocracy are each special cases of a single, compelling notion of "meritocracy.". (shrink)

There is a close conceptual relation between the notions of religious disenchantment and scientific naturalism. One way of resisting philosophical and cultural implications of the scientific image and the subsequent process of disenchantment can be found in attempts at sketching a reenchanted worldview. The main issue of accounts of reenchantment can be a rejection of scientific results in a way that flies in the face of good reason. Opposed to such reenchantment is scientific naturalism which implies an entirely disenchanted worldview. (...) However, one of the main problems of scientific naturalism are placement problems. A reenchanted worldview does have the conceptual resources to avoid placement problems, yet seems to throw out the baby with the bathwater. A dilemma results: the Scylla of an undesirable scientific naturalism and the Charybdis of a rampant, seemingly prescientific reenchanted worldview. In this article I argue that there is a safe middle passage between these two options, i.e. the recently proposed liberal naturalism which allows for a moderate normative reenchantment. Liberal naturalism lets us have it both ways: avoiding the placement problems while retaining a necessary and reasonable adherence to science, thereby avoiding both an all-too restrictive scientific naturalism.

I propose a new formalist account of legal (/proximate) causation – one that holds legal causation to be a matter of amoral, descriptive fact. The account starts with a metaphysical relation, akin to but distinct from common-sense causation, and it argues that legal causation aligns exactly with that relation; it is unified and principled.

Though the social world is real and objective, the way that social facts arise out of other facts is in an important way shaped by human thought, talk and behaviour. Building on recent work in social ontology, I describe a mechanism whereby this distinctive malleability of social facts, combined with the possibility of basic human error, makes it possible for a consistent physical reality to ground an inconsistent social reality. I explore various ways of resisting the prima facie case for (...) social inconsistency. I conclude, however, that the prima facie case survives scrutiny, and draw out some of the ramifications.

Much recent work on explanation in the interventionist tradition emphasizes the explanatory value of stable causal generalizations—i.e., causal generalizations that remain true in a wide range of background circumstances. We argue that two separate explanatory virtues are lumped together under the heading of `stability’. We call these two virtues breadth and guidance respectively. In our view, these two virtues are importantly distinct, but this fact is neglected or at least under-appreciated in the literature on stability. We argue that an adequate (...) theory of explanatory goodness should recognize breadth and guidance as distinct virtues, as breadth and guidance track different ideals of explanation, satisfy different cognitive and pragmatic ends, and play different theoretical roles in helping us understand the explanatory value of mechanisms. Thus keeping track of the distinction between these two forms of stability yields a more accurate and perspicuous picture of the role that stability considerations play in explanation. (shrink)

This paper challenges Thi Nguyen's argument, in Games: Agency as Art, a central part of the value of game-play comes from the aesthetic experiences it allows, especially of our own agency, so playing a game is importantly like engaging with art. It challenges three arguments Nguyen makes in support of this view and argues, to the contrary, that the principal value in game-play rests in the achievments it allows.

What are the truth conditions of want ascriptions? According to an influential approach, they are intimately connected to the agent’s beliefs: ⌜S wants p⌝ is true iff, within S’s belief set, S prefers the p worlds to the not-p worlds. This approach faces a well-known problem, however: it makes the wrong predictions for what we call (counter)factual want ascriptions, wherein the agent either believes p or believes not-p—for example, ‘I want it to rain tomorrow and that is exactly what is (...) going to happen’ or ‘I want this weekend to last forever, but of course it will end in a few hours’. We solve this problem. The truth conditions for want ascriptions are, we propose, connected to the agent’s conditional beliefs. We substantiate this connection by pursuing a striking parallel between (counter)factual and non-(counter)factual want ascriptions on the one hand and counterfactual and indicative conditionals on the other.

This essay critically assesses Roman Ingarden’s 1915 review of the second edition of Edmund Husserl’s Logical Investigations. I elucidate and critique Ingarden’s analysis of the differences between the 1901 first edition and the 1913 second edition. I specifically examine three tenets of Ingarden’s interpretation. First, I demonstrate that Ingarden correctly denounces Husserl’s claim that he only engages in an eidetic study of consciousness in 1913, as Husserl was already performing eidetic analyses in 1901. Second, I show that Ingarden is misguided, (...) when he asserts that Husserl had fully transformed his philosophy into a transcendental idealism in the second edition. While Husserl does appear to adopt a transcendental phenomenology by asserting–in his programmatic claims–that the intentional content and object are now included in his domain of research, he does not alter his actual descriptions of the intentional relationship in any pertinent manner. Third, I show Ingarden correctly predicts many of the insights Husserl would arrive at about logic in his late philosophy. This analysis augments current readings of the evolution of Ingarden’s philosophy, by more closely examining the development of his largely neglected early thought. I execute this critical assessment by drawing both from Husserl’s later writings and from recent literature on the Investigations. By doing so, I hope to additionally demonstrate how research on the Investigations has matured in the one hundred years since the release of that text, while also presenting my own views concerning these difficult interpretative issues.

This essay examines how Husserl stretches the bounds of his philosophy of meaning, according to which all propositions are categorical, to account for existential propositions, which seem to lack predicates. I examine Husserl’s counterintuitive conclusion that an existential proposition does possess a predicate and I explore his endeavor to pinpoint what that predicate is. This goal is accomplished in three stages. First, I examine Husserl’s standard theory of predication and categorial intuition from his 1901 Logical Investigations. Second, I show how (...) Husserl imposes those 1901 insights to uncover the predicate of the existential proposition in unpublished manuscripts and lectures. He determines that the existential proposition predicates of the subject, that it corresponds to an actual object. This analysis reveals that Husserl’s descriptions of existential propositions from the late 1890s employed both static and genetic methodologies. In those texts, he carefully untangles and clarifies the co-enmeshed passive and active moments of consciousness and shows that the passive givenness of certain circumstances is the condition of possibility for our active verifying of propositions. Finally, I execute a critical assessment of Husserl’s thought to reveal that, while his insights about existential propositions are largely correct, they are augmented by re-construing them within the context of his mature philosophy. Only by renouncing his metaphysical neutrality and by accounting for intersubjectivity, can Husserl properly clarify existential propositions. (shrink)

In Pietroski ( 2018 ) a simple representation language called SMPL is introduced, construed as a hypothesis about core conceptual structure. The present work is a study of this system from a logical perspective. In addition to establishing a completeness result and a complexity characterization for reasoning in the system, we also pinpoint its expressive limits, in particular showing that the fourth corner in the square of opposition (“ Some_not ”) eludes expression. We then study a seemingly small extension, called (...) SMPL +, which allows for a minimal predicate-binding operator. Perhaps surprisingly, the resulting system is shown to encode precisely the concepts expressible in first-order logic. However, unlike the latter class, the class of SMPL + expressions admits a simple procedural (context-free) characterization. Our contribution brings together research strands in logic—including natural logic, modal logic, description logic, and hybrid logic—with recent advances in semantics and philosophy of language.

In answering normative questions, researchers sometimes appeal to the concept of basic needs. Their guiding idea is that our first priority should be to ensure that everybody is able to meet these needs—to have enough in terms of food, water, shelter, and so on. This article provides an opinionated overview of basic needs in normative contexts. Any basic needs theory must answer three questions: (1) What are basic needs? (2) To what extent do basic needs generate reasons for action and (...) how are these reasons to be understood? (3) How are basic needs and their satisfaction to be measured? I address these questions in turn. Then I also briefly discuss the theoretical potential of appealing to basic needs in normative contexts. It turns out that future research in this area could benefit from a higher degree of interdisciplinarity and methodological reflection, and that, generally speaking, basic needs theories are more promising than they have often been claimed to be.

This paper examines the differences between moralist, realist, and pragmatist approaches to political legitimacy by articulating their largely implicit views of judgment. Three claims are advanced. First, the salient opposition among approaches to legitimacy is not between “moralism” and “realism.” Recent realist proposals for rethinking legitimacy share with moralist views a distinctive form, called “normativism”: a quest for knowledge of principles that solve the question of legitimacy. This assumes that judging legitimacy is a matter of applying such principles to a (...) case at hand. Second, neither Rawls nor Habermas is a normativist about political legitimacy. The principles of legitimacy they proffer claim to express rather than adjudicate the legitimacy of a liberal-democratic regime, and thus cannot solve the question of legitimacy at a fundamental level. But perhaps we should question the normativist aspiration to theoretically resolving the problem to begin with. My third claim is that a “pragmatist” approach enables us to rethink political legitimacy more deeply by shifting focus from the articulation of principles to the activity of judging. Implicit in Rawls’s and Habermas’s theories I then find clues towards an alternative account of judgment, in which the question of legitimacy calls not for theoretical resolution but for ongoing practical engagement.

This paper accomplishes two tasks. First, I unpack Husserl’s analysis of interest from his 1893 manuscript, “Notes Towards a Theory of Attention and Interest” to demonstrate that it comprises his first rigorous genetic analysis of attention. Specifically, I explore Husserl’s observations about how attentive interest is passively guided by affections, moods, habits, and cognitive tensions. In doing so, I reveal that the early Husserl described attention as always pulled forward to new discoveries via the rhythmic recurrence of tension and pleasure. (...) Second, I demonstrate that “Notes” is the germ of Husserl’s mature genetic phenomenology of attention. The 1893 analysis provides Husserl with all of the philosophical reasons and tools for the construction of his genetic account of attention in his late works. I then discuss how the disclosure of this novel subterranean link can prompt a rethinking of the development of phenomenology. (shrink)

In this paper we analyze how the semantics of the Alternating-time Temporal Logic ATL$^*$ deals with agents' commitments to strategies in the process of formula evaluation. In (\acro{atl}$^*$), one can express statements about the strategic ability of an agent (or a coalition of agents) to achieve a goal $\phi$ such as: ``agent $i$ can choose a strategy such that, if $i$ follows this strategy then, no matter what other agents do, $\phi$ will always be true''. However, strategies in \acro{atl} are (...) \emph{revocable} in the sense that in the evaluation of the goal $\phi$ the agent $i$ is no longer restricted by the strategy she has chosen in order to reach the state where the goal is evaluated. -/- Here we discuss some alternatives leading to amendments of that semantics. In particular, we consider variants of \acro{atl}$^*$ where strategies, on the contrary, are \emph{irrevocable}. Unlike in the standard semantics of \acro{atl}, memory plays an essential role in the semantics based on irrevocable strategies. -/- Further, we propose and discuss various syntactic and semantics mechanisms for handling commitments to strategies and release from such commitments in the semantics of ATL$^*$, leading to more expressive and semantically refined versions of that logic.

According to the recent Perceptual Confidence view, perceptual experiences possess not only a representational content, but also a degree of confidence in that content. The motivations for this view are partly phenomenological and partly epistemic. We discuss both the phenomenological and epistemic motivations for the view, and the resulting account of the interface between perceptual experiences and degrees of belief. We conclude that, in their present state of development, orthodox accounts of perceptual experience are still to be favoured over the (...) perceptual confidence view. (shrink)

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

This chapter considers how Liberal Naturalism interacts with the main problems and theories in the philosophy of perception. After briefly summarising the traditional philosophical problems of perception and outlining the standard philosophical theories of perceptual experience, it discusses whether a Liberal Naturalist outlook should incline one towards or away from any of these standard theories. Particular attention is paid to the work of John McDowell and Hilary Putnam, two of the most prominent Liberal Naturalists, whose work was also very influential (...) in the philosophy of perception. There is also a section focusing on colour, an especially important topic not only for debates about perceptual experience but also for debates concerning how our ‘manifest image’ of the natural world relates to our best theories in the physical sciences.

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes, colors, and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve experiencing ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, and moral properties. An important dialectical tool in the debate between Rich and Sparse theorists is the (...) so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low-level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

I consider cases where you increase the risk that, e.g., someone will die, without increasing the risk that you will kill them: in particular, cases in which that increasing of risk is accompanied by a decreasing of risk of the same degree such that the risk imposition has been offset. I defend the moral legitimacy of such offsetting, including carbon-offsetting.

In recent years an increasing number of psychologists have begun to explore the prevalence, causes and effects of ordinary people’s intuitions about moral realism. Many of these studies have lacked in construct validity, i.e., they have failed to measure moral realism. My aim in this paper accordingly is to motivate and guide methodological improvements. In analysis of prominent existing measures, I develop general recommendations for overcoming ten prima facie serious worries about research on folk moral realism. G1 and G2 require (...) studies’ answer choices to be as metaethically comprehensive as methodologically feasible. G3 and G4 prevent fallacious inferences from intuitions about related debates. G5 and G6 limit first-order moral and epistemic influences. G7 address studies’ instructions. And G8 and G9 suggest tests of important psychological presuppositions. (shrink)

Existing research suggests that people's judgments of actual causation can be influenced by the degree to which they regard certain events as normal. We develop an explanation for this phenomenon that draws on standard tools from the literature on graphical causal models and, in particular, on the idea of probabilistic sampling. Using these tools, we propose a new measure of actual causal strength. This measure accurately captures three effects of normality on causal judgment that have been observed in existing studies. (...) More importantly, the measure predicts a new effect ("abnormal deflation"). Two studies show that people's judgments do, in fact, show this new effect. Taken together, the patterns of people's causal judgments thereby provide support for the proposed explanation. (shrink)

In Writing the Book of the World, Ted Sider argues that David Lewis’s distinction between those predicates which are ‘perfectly natural’ and those which are not can be extended so that it applies to words of all semantic types. Just as there are perfectly natural predicates, there may be perfectly natural connectives, operators, singular terms and so on. According to Sider, one of our goals as metaphysicians should be to identify the perfectly natural words. Sider claims that there is a (...) perfectly natural first-order quantifier. I argue that this claim is not justified. Quine has shown that we can dispense with first-order quantifiers, by using a family of ‘predicate functors’ instead. I argue that we have no reason to think that it is the first-order quantifiers, rather than Quine’s predicate functors, which are perfectly natural. The discussion of quantification is used to provide some motivation for a general scepticism about Sider’s project. Shamik Dasgupta’s ‘generalism’ and Jason Turner’s critique of ‘ontological nihilism’ are also discussed. (shrink)

The theory of collective agency and intentionality is a flourishing field of research, and our understanding of these phenomena has arguably increased greatly in recent years. Extant theories, however, are still ill-equipped to explain certain aspects of collective intentionality. In this article we draw attention to two such underappreciated aspects: the failure of the intentional states of collectives to supervene on the intentional states of their members, and the role of non-human factors in collective agency and intentionality. We propose a (...) theory of collective intentionality which builds on the ‘interpretationist’ tradition in metasemantics and the philosophy of mind as initiated by David Lewis and recently developed further by Robbie Williams. The collective-level analogue of interpretationism turns out to look different in some ways from the individual-level theory, but is well-suited to accommodating phenomena such as hybrid collective intentionality. Complemented with Kit Fine’s theory of variable embodiment, such a theory also provides a diachronic account of intentional collectives. (shrink)

According to Rainer Forst, (i) moral and political claims must meet a requirement of reciprocal and general acceptability (RGA) while (ii) we are under a duty in engaged discursive practice to justify such claims to others, or be able to do so, on grounds that meet RGA. The paper critically engages this view. I argue that Forst builds a key component of RGA, i.e., reciprocity of reasons, on an idea of the reasonable that undermines both (i) and (ii): if RGA (...) builds on this idea, RGA is viciously regressive and a duty of justification to meet RGA fails to be agent transparent. This negative result opens the door for alternative conceptions of reciprocity and generality. I then suggest that a more promising conception of reciprocity and generality needs to build on an idea of the reasonable that helps to reconcile the emancipatory or protective aspirations of reciprocal and general justification with its egalitarian commitments. But this requires to downgrade RGA in the order of justification and to determine on prior, substantive grounds what level of discursive influence in reciprocal and general justification relevant agents ought to have.

We can cause windows to break and we can break windows; we can cause villages to flood and we can flood villages; and we can cause chocolate to melt and we can melt chocolate. Each time these can come apart: if, for example, A merely instructs B to break the window, then A causes the window to break without breaking it herself. Each instance of A breaking/flooding/melting/burning/killing/etc. something, is an instance of what I call making. I argue that making is (...) an independent, theoretically important notion—akin but irreducible to causing—and metaphysicians should pay attention to it. (shrink)

The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific anomalies and instead allowed for extended periods of normal science where new methodologies and concepts are developed. The basic chemical element provides this exploration with direction and explanation and has shown to be a central and historically adaptable concept for a theory of matter far from the reductionist frontier. This (...) is explored in the histories of Prout’s hypothesis, Döbereiner Triads, element inversions necessary when ordering chemical elements by atomic weights, and van den Broeck’s ad-hoc proposal to switch to nuclear charges instead. The development of more accurate methods to determine atomic weights, Rayleigh and Ramsey’s gas separation and analytical techniques, Moseley’s X-ray spectroscopy to identify chemical elements, and more recent accelerator-based cold fusion methods to create new elements at the end of the Periodic Table point to the importance of methodological development complementing conceptual advances. I propose to frame the crossover from physics to chemistry not as a loss of accuracy and precision but as an increased application of vague concepts such as similarity which permit classification. This approach provides epistemic flexibility to adapt to scientific anomalies and the continued growth of chemical compound space and rejects the Procrustean philosophy of reductionist physics. Furthermore, it establishes chemistry with its explanatory and operational autonomy epitomized by the periodic system of elements as a gateway to other experimental sciences. (shrink)

Behavioural economics has taught us that human agents don't always display consistent, context-independent and stable preferences in their choice behaviour. Can we nevertheless do welfare economics...

In Plato’s Protagoras, Socrates argues that ‘the many’ are confused about the experience they describe as ‘being overcome by pleasure’. They think the cause is ‘something other than ignorance’. He argues it follows from what they believe that the cause is ‘ignorance’ and ‘false belief’. I show that his argument depends on a premise he does not introduce but they should deny: that when someone is overcome by pleasure, the desire stems from a belief. To explain why Plato does not (...) make Socrates introduce this premise, the account I construct is speculative. It starts from the assumption that Plato is thinking through an understanding of human beings and what they must do to live good lives that he takes the historical Socrates to set out. (shrink)

The rich have two defining capabilities: independence from and command over others. These make being wealthy very pleasant indeed, but they are also toxic to democracy. First, I analyse the mechanisms by which the presence of very wealthy individuals undermines the two pillars of liberal democracy, equality of citizenship and legitimate social choice. Second, I make a radical proposal. If we value the preservation of democracy we must limit the amount of wealth any individual can have and still be a (...) citizen of our polity. (shrink)
