Multidimensional adjectives are ubiquitous in natural language. An adjective F is multidimensional just in case whether F applies to an object or pair of objects depends on how those objects stand ...

I present two arguments that aim to establish logical limits on what we can know. More specifically, I argue for two results concerning what we can know about questions that we cannot answer. I also discuss a line of thought, found in the writings of Pierce and of Rescher, in support of the idea that we cannot identify specific scientific questions that will never be answered.

Realists about possible worlds typically identify possible worlds with abstract objects, such as propositions or properties. However, they face a significant objection due to Lewis (1986), to the effect that there is no way to explain how possible worlds-as-abstract objects represent possibilities. In this paper, I describe a response to this objection on behalf of realists. The response is to identify

Social ontologists commonly think that our ideas about social entities, and about other people also inhabiting the social realm, play an important role in making those entities into what they are. At the same time, we know that our ideas are often indeterminate in character, which presumably would mean that this indeterminacy should carry over to the social realm. And yet social indeterminacy is a

One of standpoint theory’s main claims is the thesis of epistemic advantage, which holds that marginalized agents have epistemic advantages due to their social disadvantage as marginalized. The epistemic advantage thesis has been argued to be true with respect to knowledge about particular dominant ideologies like classism and sexism, as well as knowledge within fields as diverse as sociology and economics

Generative artificial intelligence has given us synthetic media that are increasingly easy to create and increasingly hard to distinguish from photographs and videos. Whereas an existing literature has been concerned with how these new media might make a difference for would-be knowers—the viewers of photographs and videos—I advance a thesis about how they will make a difference for would-be communicators—those

This response to a commentary on “Allocation of scarce resources, disability, and parity” considers whether a difference that would be morally relevant when choosing which of two people to save retains its relevance if this would affect other people’s chances of being saved.

What is praise? I argue that we can make progress by examining what praise does. Functionalist views of praise are emerging, but I here argue that by foregrounding cases in which expressions of praise are rejected by their direct target, we see that praise has a wider, and largely overlooked, social function. I introduce cases in which praise is rejected, and develop a functionalist account of praise

I argue against mnemic reliabilism, an influential view that successful remembering must be produced by a reliable memory process. Drawing on empirical evidence from psychology and neuroscience, I refute mnemic reliabilism by demonstrating that: (1) patients with memory impairments (e.g., Alzheimer’s disease) can also successfully remember the past despite the unreliability of their corresponding memory

Recently, metaphysical coherentism has been propounded as an alternative to metaphysical foundationalism and infinitism. The view replaces the picture of reality as a hierarchy of levels with that of a network of objects or facts standing in symmetric or, more generally, cyclic relations of metaphysical dependence. This paper defends the orthodox picture of a well-founded hierarchy against the claimed

Modes of presentation (MOPs) are often said to have to be transparent, usually in the sense that thinkers can know solely via introspection whether or not they are deploying the same one. While there has been much discussion of threats to transparency stemming from externalism, another threat to transparency has garnered less attention. This novel threat arises if MOPs are robust, as I argue they should

This article considers the possible relation between the idea of parity and some past work on the allocation of scarce resources. Parity of value is first connected with the idea of some goods being irrelevant in interpersonal comparisons. The notion of moral parity is introduced to describe the recognition that people who are moral equals (even when they are not on a par in terms of value) as not

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

Threats to the stability of liberal democracies are of obvious contemporary import. Concern with stability runs through John Rawls’s work. The stability that concerned him was that of fundamental terms of cooperation. Rawls long believed that the terms which would be stable were his two principles, but he eventually conceded that even a well-ordered society was more likely to be characterized by “justice

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

This paper introduces a new form of virtue ethics—patient-centered virtue ethics—and argues that it is better placed to compete with Contractualism, Kantianism, and Utilitarianism, than existing agent and target-focused forms of virtue ethics. The opening part of the paper draws on T.M. Scanlon’s methodological insights to clarify what a theory of narrow morality should aim to accomplish, and the remaining

1 INTRODUCTION Intellectualists, in one sense of the term, hold that knowing how to do something (knowing how) is reducible to knowing that something is the case (knowing that), while their opponents deny this. Intellectualists therefore believe in the unity of knowledge—at least where these two forms of knowledge are concerned—whereas anti-intellectualists generally believe that there are at least

Standard accounts hold that regularities of behavior must be arbitrary to constitute a convention. Yet, there is growing consensus that conventionality is a graded phenomenon, and that conventions can be more or less natural. I develop an account of natural conventions that distinguishes two basic dimensions of conventional naturalness: a probabilistic dimension and an inherent one. A convention is

The Geach-Kaplan sentence is alleged to be an example of a non-first-orderizable sentence, and the proof of the alleged non-first-orderizability is credited to David Kaplan. However, there is also a widely shared intuition that the Geach-Kaplan sentence is still first-orderizable by invoking sets or other extra non-logical resources. The plausibility of this intuition is particularly crucial for first-orderism

Public-policy choices frequently have to be carried out in the presence of incommensurabilities. These incommensurabilities may manifest themselves in the form of incompleteness—that is, some of the options under consideration are not comparable by a decision maker. As a consequence, it may be impossible to select policies that are at least as good as all competing proposals. When faced with incommensurabilities

It is widely agreed that ignorance of fact exculpates, but does moral ignorance exculpate? If so, does it exculpate in the same way as non-moral ignorance? In this paper I will argue that on one family of views explaining exculpating non-moral ignorance also explains exculpating moral ignorance. The view can be loosely stated in the following way: ignorance counts as an excuse only if it is not the

A growing number of epistemologists have endorsed the Ignorance Norm for Inquiry. Roughly, this norm says that one should not inquire into a question unless one is ignorant of its answer. I argue that, in addition to ignorance, proper inquiry requires a certain kind of knowledge. Roughly, one should not inquire into a question unless one knows it has a true answer. I call this the Knowledge Norm for

Stalnaker’s Thesis about indicative conditionals says, roughly, that the probability one ought to assign to an indicative conditional is equal to the probability that one ought to assign to its consequent conditional on its antecedent. Skyrms’s Thesis about counterfactual conditionals says, roughly, that the probability that one ought to assign to a counterfactual conditional equals one’s rational

According to many philosophers, rationality is, at least in part, a matter of one’s attitudes cohering with one another. Theorists who endorse this idea have devoted much attention to formulating v...

I argue for an account of grasping, or understanding that, on which we grasp via a higher-order mental act of Husserlian fulfillment. Fulfillment is the act of matching up the objects of our phenomenally presentational experiences with those of our phenomenally representational thought. Grasping-by-fulfilling is importantly different from standard epistemic aims, in part because it is phenomenal rather

According to the Epistemic Theory of Mind, knowledge is part of the best overall framework for explaining behavior at the psychological level. This theory, which has become increasingly popular in recent decades, has almost always been conjoined with an invariantist theory of “knows.” In this paper, I argue that this is a mistake: the Epistemic Theory of Mind is far more explanatorily powerful when

A new wave of evidentialist theorizing concedes that evidentialism may be extensionally incorrect as an account of all-things-considered rational belief. Nevertheless, these newer evidentialists maintain that there is an importantly distinct type of epistemic rationality about which evidentialism may be the correct account. I argue that natural ways of developing the newer evidentialist position face

Measuring an individual’s health states presupposes the ability to compare them. I maintain that our ability to compare quantities or magnitudes of health are severely limited. It is easier to compare values of health states, but those values are context dependent and often unreliable.

A number of philosophers have recently argued for acknowledging non-augmented partial grounds, partial grounds that are not parts of full grounds. This paper shows how non-augmented partial grounds can be straightforwardly modelled within the framework of generalised identity. I argue that my proposal answers questions concerning the connections between partial grounding, full grounding, and nothi

The classic formulation of causal decision theory (CDT) appeals to counterfactuals. It says that you should aim to choose an option that would have a good outcome, were you to choose it. However, this version of CDT faces trouble if the laws of nature are deterministic. After all, the standard theory of counterfactuals says that, if the laws are deterministic, then if anything—including the choice

How should we respond to moral theories that put excessive demands on individual agents? Intramoral strategies concern the content of morality and set limits on how exacting moral demands may be. Extramoral strategies concern the normative status of morality and set limits on how significant moral demands may be. While both strategies are often discussed separately, I focus on a specific aspect of

A minimal constraint on normative reasons seems to be that if some fact is a reason for an agent to φ (act, believe, or feel), the agent could come to know that fact. This constraint is threatened by a well-known type of counterexamples. Self-effacing reasons are facts that intuitively constitute reasons for an agent to φ, but that if they were to become known, they would cease to be reasons for that

Many philosophers endorse the Transparency Thesis, the claim that by introspection one cannot become aware of one's experience. Recently, some authors have suggested that the Transparency Thesis is challenged by introspective states reached under mindfulness. We label this the Mindfulness Opacity Hypothesis. The present paper develops the hypothesis in important new ways. First, we motivate the hypothesis

This paper proposes an account of why proof is the only way to acquire knowledge of some mathematical proposition’s truth. Admittedly, non-deductive arguments for mathematical propositions can be s...

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

Comparative cognitive science often involves asking questions like ‘Do nonhumans have C?’ where C is a capacity we take humans to have. These questions frequently generate unproductive disagreements, in which one party affirms and the other denies that nonhumans have the relevant capacity on the basis of the same evidence. I argue that these questions can be productively understood as questions about

1 PRECIS Moral Knowledge addresses, and argues for answers to, a wide range of questions within moral epistemology, including questions about the sources of moral knowledge, the strengths and weaknesses of the method of reflective equilibrium as an answer to the question of where moral knowledge and justification come from, questions about moral testimony and moral expertise, and questions about the

Some normative theories are self-defeating. They tell us to respond to our situations in ways that bring about outcomes that are bad, given the aims of the theories, and which could have been avoided. Across a wide range of debates in ethics, decision theory, political philosophy, and formal epistemology, many philosophers treat the fact that a normative theory is self-defeating as sufficient grounds

This paper argues that Aristotelian practical wisdom (phronēsis) is a state of conviction (pistis) in the goodness of our goals based on proper grounds. This state of conviction can only be achieved if rational arguments and principles agree with how things appear to us. Since, for Aristotle, passions influence appearances, they can support or undermine our conviction in the goodness of ends . For

A ‘bad feminist’ is someone who endorses feminist ideals and values but finds themselves falling short of them. Since bad feminists exhibit an inconsistency between what they say and what they do, this can generate worries about hypocrisy. This article investigates whether and when members of political movements with certain ideals ought to worry they are being hypocritical. It first provides a diagnosis

It is an honor to receive such careful and attentive criticism. In this response, I attempt to put the criticisms of the reasons latesters into the context of my argumentative aims in the book and to point toward how they might be answered.

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.

My aim in this article is to contribute to defences of working time policies by attempting to meet an objection that comes from those who condemn these measures on the alleged grounds that they reduce economic output. What is more, as I emphasize throughout, it is possible to rebut such a concern in a fashion that is consistent with the demands of liberal anti-perfectionism. In itself, this is a philosophically

We commonly explain the distinctive prudential and moral status of persons in terms of our mental capacities. I draw from recent work to argue that the common explanation is incomplete. I then develop a new explanation: We are ethically important because we are the object of a pattern of self-concern. I argue that the view solves moral problems posed by permissive ontologies, such as the recent personite

What is computational explanation? Many accounts treat it as a kind of causal explanation. I argue against two more specific versions of this view, corresponding to two popular treatments of causal explanation. The first holds that computational explanation is mechanistic, while the second holds that it is interventionist. However, both overlook an important class of computational explanations, which

This article defends the existence of borderline consciousness. In borderline consciousness, conscious experience is neither determinately present nor determinately absent, but rather somewhere between. The argument in brief is this. In considering what types of systems are conscious, we face a quadrilemma. Either nothing is conscious, or everything is conscious, or there’s a sharp boundary across

Mark Schroeder’s Reasons First is admirable in its scope and execution, deftly demonstrating the theoretical promise of extending the reasons-first approach from ethics to epistemology. In what follows we explore how (not) to account for the evidence-that relation within the reasons-first program, we explain how factive content views of evidence can be resilient in the face of Schroeder’s criticisms

Some incredibly far-fetched conspiracy theories circulate online these days. For most of us, clear evidence would be required before we’d believe these extraordinary theories. Yet, conspiracists often cite evidence that seems transparently very weak. This is puzzling, since conspiracists often aren’t irrational people who are incapable of rationally processing evidence. I argue that existing accounts

What is involved in acting together with others? Most shared agency theorists endorse the Shared Intention Thesis, i.e., the claim that shared agency necessarily involves shared intentions. This article dissents from this orthodoxy and offers a minimalist account of shared agency—one where parties to shared activities need not form rich webs of interrelated psychological states. My account has two

Levinstein recently presented a challenge to accuracy-first epistemology. He claims that there is no strictly proper, truth-directed, additive, and differentiable scoring rule that recognises the contingency of varying importance, i.e., the fact that an agent might value the inaccuracy of her credences differently at different possible worlds. In my response, I will argue that accuracy-first epistemology

There is a well-known argument against irreducibly normative properties that appeals to the following claim about supervenience: for all possible worlds W and W*, if the instantiation of descriptive properties in W and W* is exactly the same, then the instantiation of normative properties in W and W* is also exactly the same. This claim used to be uncontroversial, but recently several philosophers

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and
