The notion of causation that Mary Shepherd develops in her 1824 An Essay Upon the Relation of Cause and Effect (ERCE) has a number of surprising features that have only recently begun to be studied by scholars. This relation is synchronic, rather than diachronic (ERCE pp. 49–50); it always involves a ‘mixture’ of pre-existing objects (ERCE pp. 46–7); and the effect must be ‘a new nature, capable of

In Piñeros Glasscock (2020) I presented a version of Williamson’s anti-luminosity argument against the Anscombean thesis that intentional action entails knowledge. I defend this argument from recent criticisms by Beddor and Pavese (2022) and Valaris (2021). I argue that contrary to what my past self and these critics suggest, the conclusion of this anti-luminosity argument does not rest on the existence

This paper examines the prospects for an expressivist theory of prudential thought and discussion, or thought and discussion about what is good for us or what makes our lives go well. It is becoming increasingly common to view prudential thought and discussion as a kind of normative thought and discussion. If this is right, then expressivism, like any other meta-normative view, must be able to explain

What is the source of normativity? According to Bengson, Cuneo and Shafer-Landau (2023), we can answer this question by identifying non-normative grounds of fundamental normative facts. To illustrate how this can be achieved, they argue that facts concerning essences of normative properties are non-normative facts, and such facts can be seen as non-normative grounds of fundamental normative facts.

The money-pump argument aims to show that cyclic preferences are irrational. The argument can be based on a number of different exploitation schemes that vary in what needs to be assumed about the agent. The Standard Money Pump works for myopic and naive agents, but not for sophisticated agents who use backward induction. The Upfront Money Pump works for sophisticated agents, but not for myopic or

We examine two competing solutions to Benardete paradoxes: causal finitism, according to which nothing can have infinitely many causes, and the unsatisfiable pair diagnosis (UPD), according to which such paradoxes are logically impossible and no metaphysical thesis need be adopted to avoid them. We argue that the UPD enjoys notable theoretical advantages over causal finitism. Causal finitists, however

One of the major challenges in the philosophy of religion is theological fatalism — roughly, the claim that divine omniscience is incompatible with free will. In this article, I present new reasons to be sceptical of what I consider to be the strongest argument for theological fatalism. First, I argue that divine foreknowledge is not necessary for an argument against free will if we take into account

Calls for decolonization are on the rise in social and academic life, but ‘decolonization’ can mean various things. This article expounds and critically evaluates the programme of conceptual decolonization, chiefly as promulgated in relation to African philosophy by Kwasi Wiredu. The programme involves both resisting the unreflective acceptance of non-indigenous concepts and constructively utilizing

It is tempting to think that a process of choosing a point at random from the surface of a sphere can be probabilistically symmetric, in the sense that any two regions of the sphere which differ by a rotation are equally likely to include the chosen point. Isaacs, Hájek and Hawthorne (2022) argue from such symmetry principles and the mathematical paradoxes of measure to the existence of imprecise chances

This paper offers a new argument against the KK thesis, which says that if you know p, then you know that you know p. We argue that KK is inconsistent with the fact that anyone denies the KK thesis: imagine that Dudley says he knows p but that he does not have 100 iterations of knowledge about p. If KK were true, Dudley would know that he has 100 iterations of knowledge about p, and so he wouldn’t

I argue that in Bertrand Russell’s An Essay on the Foundations of Geometry (1897), his forms of externality serve the same fundamental role in grounding the possibility of geometry that Immanuel Kant’s forms of intuition serve in grounding geometry in his critical philosophy. Specifically, both provide knowledge of bare numerical difference, where we have no concept of this difference. Because geometry

This paper defends the Intention Account of Individual Inquiry. On this account, inquiry is best understood by appeal to a ‘question-directed intention’ (QDI), an intention to answer a question broadly construed. This account’s core commitments help meet recent challenges plaguing extant approaches to characterizing inquiry. First, QDIs are the type of mental state central to inquiry, not attitudes

Katie Steele and H. Orri Stefánsson argue that, to reflect an agent’s limited awareness, the algebra of propositions on which that agent’s credences are defined should be relativised to their awareness state. I argue that this produces insurmountable difficulties. But the project of relativising the agent’s algebra to reflect their partial perspective need not be abandoned: the algebra can be relativised

Elizabeth Anscombe characterised practical knowledge as knowledge ‘in intention’. As Anscombe recognised, accepting this view involves rejecting certain basic orthodox epistemological assumptions. But even once this is done, a challenge remains for a conception of practical knowledge as knowledge ‘in intention’. For while practical knowledge would appear to be a kind of propositional knowledge, intentions

Initially, you judge that p. You then learn that most experts disagree. All things considered, you believe that the experts are probably right. Still, p continues to seem right to you, in some sense. You don’t yet see what, if anything, is wrong with your original reasoning. In such a case, we’ll say that you are ‘inclined’ toward p. This paper explores various roles that this state of inclination

In this paper we motivate the ‘principles of trust’, chance-credence principles that are strictly stronger than the New Principle yet strictly weaker than the Principal Principle, and argue, by proving some limitative results, that the principles of trust conflict with Humean Supervenience.

This paper defends a version of epistemic contextualism that accounts for the ordinary judgements and theoretical principles that motivate pragmatic encroachment. Adopting this contextualist view, we can avoid the counterintuitive consequences of pragmatic encroachment, while still preserving its attractive applications.

This note is a critical response to Kentaro Fujimoto’s new conservativeness argument about truth, which centres on the notion of finite conjunction. We argue that Fujimoto’s arguments turn on a specific way of formalizing the notions of finite collection and finite conjunction in first-order logic. In particular, by instead formalizing these concepts in a natural way in set theory or in second-order

We are typically near-future biased, prioritising our present and near-future interests over our own distant-future interests. This bias can be directed at others as well, prioritising their present and near-future interests over their distant-future interests. I argue that, given these biases, and given a plausible limit on the extent to which we can permissibly prioritise our present interests over

Over the past two decades, modal epistemology has turned its attention to ordinary modal knowledge. This paper brings to the fore a neglected but central form of ordinary modal knowledge: knowledge of agentive modality, and in particular of our own abilities, which I call ‘ability knowledge’. I argue that modal epistemology as it is does not account for ability knowledge, by looking at the most promising

According to the worm theory, persons are (maximal) aggregates of person-stages existing at different times. Personites, on the other hand, are non-maximal aggregates of stages that are very much like persons. Their existence appears to make instances of prudential self-sacrifice morally problematic: the personites that exist at the time of the sacrifice but not at the time of the reward seem not to

The topic of this paper is Aristotle’s ‘proof by refutation’ of the Principle of Non-Contradiction (Metaphysics Γ 4, 1006a11–1007a20). I consider a worry which has often been raised in connection with this proof. The worry is that, faced with an opponent who is prepared to tolerate contradictions, the argument is dialectically powerless: it is incapable of getting them to abandon their position. In

This essay argues for a relationist treatment of intentional identity sentences like (1): (1) Hob believes that a witch blighted Bob’s mare and Nob believes that she killed Cob’s sow. According to relationism, facts of the form a believes that ϕ and b believes that ψ are not in general reducible to facts of the form c believes that χ. I first argue that extant, non-relationist treatments of intentional

This paper is a discussion note on Isaacs, Hájek and Hawthorne (2022), which claims to offer a new motivation for imprecise probabilities, based on the mathematical phenomenon of non-measurability. In this note, I clarify some consequences of that proposal. In particular, I show that if the proposal is applied to a bounded 3-dimensional space, then one has to reject at least one of the following: •

I chart the philosophical development of neglected figure Margaret Macdonald and situate that development in the context of mid-century analytic philosophy more broadly. I examine Macdonald’s changing attitude towards verificationism, and show that these changing views led her, in 1950 and beyond, to a very thorough appreciation of language use as capable of being employed in the execution of distinctive

There is an apparent tension in Shepherd’s accounts of space and time. Firstly, Shepherd explicitly claims that we know that the space and time of the unperceived world exist because they cause our phenomenal experience of them. Secondly, Shepherd emphasizes that empty space and time do not have the power to effect any change in the world. My proposal is that for Shepherd time has exactly one causal

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators express sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defence of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies

How is Nietzsche’s genealogy of morality relevant to his revaluation of values? I consider and reject three accounts: contingency accounts, pedigree accounts, and unmasking accounts. I then propose an alternative account. On this view, Nietzsche provides a ‘deconstructive genealogy’ that indicates whether and where we should expect to find unity in our current moral practices. Moreover, Nietzsche’s

Inquiry aims at knowledge. Your inquiry into a question succeeds just in case you come to know the answer. However, combined with a common picture on which misleading evidence can lead knowledge to be lost, this view threatens to recommend a novel form of dogmatism. At least in some cases, individuals who know the answer to a question appear required to avoid evidence bearing on it. In this paper,

Throughout his lectures and published writings on anthropology, Kant describes a form of unintentional, unstructured, obscure, and pleasurable imaginative mental activity, which he calls fantasy (Phantasie), where we ‘take pleasure in letting our mind wander about in obscurity’ (LA 25:480). In the context of his pragmatic anthropology, Kant is concerned not only to describe this form of mental activity

I present a novel account of unconditional obligation and of its relationship to conditional obligation and bring this account to bear upon Chisholm's puzzle concerning contrary-to duty obligation.

Mill advocates plural voting on instrumentalist grounds: the more competent are to have more votes. At the same time, he regards it as a ‘personal injustice’ to withhold from anyone ‘the ordinary privilege of having his voice reckoned in the disposal of affairs in which he has the same interest as other people’ (Mill 1861a, p. 469). But if electoral voice is justified by its contribution to good governance

In this paper, I argue against recent modifications of the Knowledge Condition on intentional action that weaken the condition. My contention is that the condition is best understood in the context of Anscombe’s Intention and, when so understood, can be maintained in its strongest form.

Conceptual engineering is the enterprise of evaluating and improving our representational devices. But how should we conduct this enterprise? One increasingly popular answer to this question proposes that conceptual engineering should proceed in terms of the functions of our representational devices. In this paper, we argue that the best way of understanding this suggestion is in terms of normative

José Benardete developed a famous paradox involving a beginningless set of items each member of which satisfies some predicate just in case no earlier member satisfies it. The Grim Reaper version of this paradox has recently been employed in favour of various finitist metaphysical theses, ranging from temporal finitism to causal finitism to the discrete nature of time. Here, I examine a new challenge

In a recent paper, Yoaav Isaacs, Alan Hájek, and John Hawthorne argue for the rational permissibility of ’credal imprecision’ by appealing to certain propositions associated with non-measurable spatial regions: for example, the proposition that the pointer of a spinner will come to rest within a certain non-measurable set of points on its circumference. This paper rebuts their argument by showing that

Kevin Dorst (2019) uses the ‘manifest unassertability’ of conditionals of the form ‘If I don’t know p, then p’ as a new motivation for the KK thesis. In this paper we show that his argumentation is misguided. Plausible heuristics offer a compelling and nuanced explanation of the relevant infelicity data. Meanwhile, Dorst relies on tools that, quite independently of KK, turn out to be rather poor predictors

There’s the question of what there is, and then there’s the question of what ultimately exists. Many contend that, once we have this distinction clearly in mind, we can see that there is no sensible debate to be had about whether there are such things as properties or tables or numbers, and that the only ontological question worth debating is whether such things are (in one or another sense) ultimate

The search for extraterrestrial life centres on the search for ‘biosignatures’. Yet there is little agreement within the scientific community with respect to what exactly it is for something to be a biosignature. Existing accounts are presented and criticised. An alternative is provided that resolves problems with existing accounts by distinguishing clearly between types and tokens.

This article explores the connection between Boolean-valued class models of set theory and the theory of arbitrary objects in roughly Kit Fine’s sense of the word. In particular, it explores the hypothesis that the set-theoretic universe as a whole can be seen as an arbitrary entity. According to this view, the set-theoretic universe can be in many different states. These states are structurally like

Hsueh M. Qu has recently argued that Hume’s famed ‘Separability Principle’ from the Treatise entangles him in a contradiction. Qu offers a modified principle as a solution but also argues that the mature Hume would not have needed to avail himself of it, given that Hume’s arguments in the first Enquiry do not depend on this principle in any form. To the contrary, I show that arguments in the first

Is well-being the kind of thing that can be summed across individuals? This paper takes a measurement-theoretic approach to answering this question. To make sense of adding well-being, we would need to identify some natural ‘concatenation’ operation on the bearers of well-being that satisfies the axioms of extensive measurement and can therefore be represented by the arithmetic operation of addition

Indicative and subjunctive conditionals are in non-complimentary distribution: there are conversational contexts at which both are licensed (Stalnaker 1975; Karttunen and Peters 1979; von Fintel 1998). This means we can ask an important, but under-explored, question: in contexts which license both, what relations hold between the two? In this paper, I’ll argue for an initially surprising conclusion:

I introduce a novel and quite intuitive interpretation of the ternary relation that figures in the relational semantics of many relevance logics. Conceptually, my interpretation makes use only of incompatibility and parthood relations, defined over a set of states. In this way, the proposed interpretation—of the ternary relation and the conditional—extends Dunn’s and Restall’s works on negation and

Pereboom’s ‘wild coincidences’ argument against agent-causal libertarianism is based on the claim that in a world governed by statistical laws, the dovetailing of indeterministic physical happenings with the free actions of agent causes would be a coincidence too wild to be credible. In this paper it is shown that the conclusion is valid for deterministic laws, but that it fails for statistical laws

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge

What degree of justification should be required of epistemological cognition, the kind of cognition by which epistemological problems are to be solved? I consider the question by examining Husserl’s view of the matter. Challenging the current consensus, I argue that he is committed to the infallibility of epistemological cognition. I first present what he takes to be the leading problem of epistemology

I defend counterfactual decision theory, which says that you should evaluate an action in terms of which outcomes would likely obtain were you to perform it. Counterfactual decision theory has traditionally been subsumed under causal decision theory as a particular formulation of the latter. This is a mistake. Counterfactual decision theory is importantly different from, and superior to, causal decision

kk states that knowing entails knowing that one knows, and K¬K states that not knowing entails knowing that one does not know. In light of the arguments against kk and K¬K, one might consider modally qualified variants of those principles. According to weak kk, knowing entails the possibility of knowing that one knows. And according to weak K¬K, not knowing entails the possibility of knowing that one

Contingentists—who hold that it is contingent what there is—are divided on the claim that having a property or standing in a relation requires being something. This claim can be formulated as a natural schematic principle of higher-order modal logic. On this formulation, I argue that contingentists who are also higher-order contingentists—and so hold that it is contingent what propositions, properties

The best accuracy arguments for probabilism apply only to credence functions with finite domains, that is, credence functions that assign credence to at most finitely many propositions. This is a significant limitation. It reveals that the support for the accuracy-first programme in epistemology is a lot weaker than it seems at first glance, and it means that accuracy arguments cannot yet accomplish

The term ‘epistemic trespassing’ has recently been coined to denote a person’s judgments regarding a domain where they are not epistemic experts. In this paper, I focus on expert trespassing testimony – that is, testimony by an expert in a domain of expertise other than his own. More specifically, I focus on intra-scientific trespassing testimony between scientific collaborators. By developing a number

According to an influential view, when it comes to representing reality, some words are better suited for the job than others. This is elitism. There is reason to believe that the set of the best, or elite, words should not be redundant or arbitrary. However, we are often forced to choose between these two theoretical vices, especially in cases involving theories that seem to be mere notational variants

There is a long-standing gap in the literature as to whether Gödelian incompleteness constitutes a challenge for Neo-Logicism, and if so how serious it is. In this paper, I articulate and address the challenge in detail. The Neo-Logicist project is to demonstrate the analyticity of arithmetic by deriving all its truths from logical principles and suitable definitions. The specific concern raised by

This paper explores an idea of Stoic descent that is largely neglected nowadays, the idea that an argument is valid when the conditional formed by the conjunction of its premises as antecedent and its conclusion as consequent is true. As will be argued, once some basic features of our naïve understanding of validity are properly spelled out, and a suitable account of conditionals is adopted, the equivalence

Communication can be risky. Like other kinds of actions, it comes with potential costs. For instance, an utterance can be embarrassing, offensive, or downright illegal. In the face of such risks, speakers tend to act strategically and seek ‘plausible deniability’. In this paper, we propose an account of the notion of deniability at issue. On our account, deniability is an epistemic phenomenon. A speaker

The nineteenth century saw the development of reductive views of attention. The German philosopher and psychologist Carl Stumpf (1848-1936) proposed an original reductive view according to which attention is nothing but interest and interest itself is a positive feeling. Stumpf’s view was developed by Francis Bradley (1846-1924), George Frederick Stout (1860-1944), and Josiah Royce (1855-1916), but

In the philosophy of perception, objects are typically frontlit. But according to Roy Sorensen, backlit objects have surprising lessons to teach us about perception. In backlit conditions, ‘the principles of occlusion are reversed’, Sorensen (2008, p. 25) maintains. In particular, he claims we see the back surfaces of backlit objects. But as I argue in this paper, Sorensen’s arguments in support of

Many theories of rational action are predicated on the idea that what it is rational to do in a given situation depends, in part, on what it is rational to believe in that situation. In short: they treat epistemic rationality as explanatorily prior to practical rationality. If they are right in doing so, it follows, on pain of explanatory circularity, that epistemic rationality cannot itself be a form

What kinds of mental states can be based on epistemic reasons? The standard answer is only beliefs. I argue that perceptual states can also be based on reasons, as the result of crossmodal interactions. A perceptual state from one modality can provide a reason on which an experience in another modality is based. My argument identifies key markers of the basing relation and locates them in the crossmodal
