The popular predictive processing (PP) framework posits prediction error minimization (PEM) as the sole mechanism in the brain that can account for all mental phenomena, including consciousness. I first highlight three ambitions associated with major presentations of PP: (1) Completeness (PP aims for a comprehensive account of mental phenomena), (2) Bayesian realism (PP claims that PEM is implemented

How is it that individuals who deny experiencing visual imagery nonetheless perform normally on tasks which seem to require it? This puzzle of aphantasia has perplexed philosophers and scientists since the late nineteenth century. Contemporary responses include: (i) idiosyncratic reporting, (ii) faulty introspection, (iii) unconscious imagery, and (iv) complete lack of imagery combined with the use

Russell famously posited a type of knowledge distinct from and irreducible to propositional knowledge, which he called knowledge by acquaintance. In recent years, several epistemologists have reignited interest in knowledge by acquaintance, pointing out an array of theoretical jobs it is serviceable in performing. Nonetheless knowledge by acquaintance continues to be met with resistance and disregard

Standard decision theory ranks risky prospects by their expected utility. This ranking does not change if the values of all possible outcomes are uniformly shifted or dilated. Similarly, if the values of the outcomes are negated, the ranking of prospects by their expected utility is reversed. In settings with unbounded levels of utility, the expected utility of prospects is not always defined, but

The modal theory of luck, according to one influential version of it, holds that an event is lucky if and only if it actually obtains but fails to obtain in some close possible worlds, holding fixed certain initial conditions for the event. There have been some notable critiques of the theory. But they are not fully satisfactory, for they succumb to two typical and compelling strategies of defending

Some modal expressions in language—for example, “can” and “able”—describe what is possible in light of someone's abilities. Ability modals are obviously related to other modalities in language, such as epistemic or deontic modality, but also give rise to anomalies that make them unique. This paper develops a general theory of ability modals that is broadly compatible with standard modal semantics,

Expected value maximization gives plausible guidance for moral decision-making under uncertainty in many situations. But it has unappetizing implications in ‘Pascalian’ situations involving tiny probabilities of extreme outcomes. This paper shows, first, that under realistic levels of ‘background uncertainty’ about sources of value independent of one's present choice, a widely accepted and apparently

If an agent can't live up to the demands of ideal rationality, fallback norms come into play that take into account the agent's limitations. A familiar human limitation is our tendency to lose information. How should we compensate for this tendency? The Seeping Beauty problem allows us to isolate this question, without the confounding influence of other human limitations. If the coin lands tails, Beauty

Suppose your evil sibling travels back in time, intending to lethally poison your grandfather during his infancy. Determined to save grandpa, you grab two antidotes and follow your sibling through the wormhole. Under normal circumstances, each antidote has a 50% chance of curing a poisoning. Upon finding young grandpa, poisoned, you administer the first antidote. Alas, it has no effect. The second

One metaphysical problem about laws is how to find appropriate truthmakers for fully general functional laws. What makes it true, for instance, that an uninstantiated mass would interact with others as prescribed by laws concerning mass? This is the missing value problem. D. M. Armstrong attempted to solve it by appeal to determinable universals. I will offer a trope-theoretic solution that, while

Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non-Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws. This proposal helps resolve several longstanding problems of nomic realism and simplicity. A key consequence is that the presumed epistemic advantage

The counterfactual comparative account of harm and benefit (CCA) has faced a barrage of objections from cases involving preemption, overdetermination, and choice. In this paper I provide a unified diagnosis of CCA's vulnerability to these objections: CCA is susceptible to them because it evaluates each act by the same criterion. This is a mistake because, in a sense I make precise, situations raise

A major open question in the borderlands between epistemology and philosophy of science concerns whether Bayesian updating and abductive inference are compatible. Some philosophers—most influentially Bas van Fraassen—have argued that they are not. Others have disagreed, arguing that abduction, properly understood, is indeed compatible with Bayesianism. Here we present two formal results that allow

Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to form. If true, this would allow conceptual engineers to

Ontic structuralists claim that there are no individual objects, and that reality should instead be thought of as a “web of relations”. It is difficult to make this metaphysical picture precise, however, since languages usually characterize the world by describing the objects that exist in it. This paper proposes a solution to the problem; I argue that when discourse is reformulated in the language

A new argument is offered which proceeds through epistemic possibility (for all S knows, p), cutting a trail from modality to Millianism, the controversial thesis that the semantic content of a proper name is simply its bearer. New definitions are provided for various epistemic modal notions. A surprising theorem about epistemic necessity is proved. A proposition p can be epistemically necessary for

Censorship involves, inter alia, adopting a certain type of epistemic policy. While much has been written on the harms and benefits of free expression and the associated rights thereof, the epistemic preconditions of justified censorship are relatively underexplored. In this paper, I argue that examining intrapersonal norms of how we ought to treat evidence that might come to us over time can shed

There are infinitely many ways the world might be, and there may well be infinitely many people in it. These facts raise moral paradoxes. We explore a conflict between two highly attractive principles: a Pareto principle that says that what is better for everyone is better overall, and a statewise dominance principle that says that what is sure to turn out better is better on balance. We refine and

Cian Dorr, Jacob Nebel, and Jake Zuehl have argued that no objects are incomparable in value. One set of arguments they offer depart from a principle they call ‘Strong Monotonicity’, which states that if x is good and y is not good, then x is better than y. In this article, we respond to those arguments, thereby defending the possibility of value incomparability.

According to many philosophers, “the meaning of life” refers to our cosmic purpose, the activity that we were created by God or a purposive universe to perform. If there is no God or teleology, there is no such thing as the meaning of life. But this need not be the last word on the matter. In this paper, I ask what the benefits provided by a cosmic purpose are, and go on to argue that thinking of our

Hume offers not one, but two definitions of virtue: a more famous one in terms of usefulness or agreeability to the self or to others, and a second in terms of eliciting approbation or disapprobation from spectators. Some scholars endorse the former definition as the more fundamental one; others endorse the latter as more fundamental. This paper argues that neither definition is more fundamental than

Expected utility theory often falls silent, even in cases where the correct rankings of options seems obvious. For instance, it fails to compare the Pasadena game to the Altadena game, despite the latter turning out better in every state. Decision theorists have attempted to fill these silences by proposing various extensions to expected utility theory. As I show in this paper, such extensions often

I extend the literature on norms of assertion to the ubiquitous use of graphs in scientific papers and presentations, which I term “graphical testimony.” On my account, the testimonial presentation of a graph involves commitment to both (a) the in-context reliability of the graph's framing devices and (b) the perspective-relative accuracy of the graph's content. Despite apparent disagreements between

It is often suggested that to make progress in consciousness science we need a theory of consciousness—one that tells us what consciousness is and what kinds of systems can have it. But this may be putting the cart before the horse. There are currently a wide range of very different theories all claiming to be theories of consciousness. How are we to decide between them if we do not already know which

The significance or vacuity of the statement, “Everything has just doubled in size,” attracted considerable attention last century from scientists and philosophers. Presenting his conventionalism in geometry, Poincaré insisted on the emptiness of a hypothesis that all objects have doubled in size overnight. Such expansion could have meaning, he argued, “only for those who reason as if space were absolute

In this paper, I attempt to articulate a version of qualitative hedonism, grounded in the value theory of the British Moralists. I argue that this view is novel, presents substantial advantages over alternative hedonisms (including rival approaches to qualitative hedonism and its quantitative cousin), and can avoid classic challenges to qualitative hedonism that emerged in the post-Mill era. If I succeed

It is widely acknowledged that the Galilean Relativity Principle, according to which the laws of classical systems are the same in all inertial frames in relative motion, has played an important role in the development of modern physics. It is also commonly believed that this principle holds the key to answering why, for example, we do not notice the orbital velocity of the Earth as we go about our

The active/passive distinction, once a hallmark of classical metaphysics, has largely been discarded from contemporary thought. The revival of powers theory has not seen an equally vigorous rehabilitation of the real distinction between active and passive powers. I begin an analysis and vindication with a critique of E.J. Lowe's discussion. I then argue that the active/passive problem is a metaphysical

Good-for theorists claim that to be valuable is to be good for someone, in the sense of being beneficial for them. Their opponents deny this, arguing that some things are good-simpliciter: good independently of being good for anyone. In this article I argue in favor of good-simpliciter. I appeal to the category of symbolically valuable acts, acts which seem valuable even when they do not benefit anyone

Russellians, Relationists, and Fregeans disagree about the nature of propositional-attitude content. We articulate a framework to characterize and evaluate this disagreement. The framework involves two claims: i) that we should individuate attitude content in whatever way fits best with the explanations that characteristically appeal to it, and ii) that we can understand those explanations by analogy

Blaming others for things that are not our business can attract charges of meddling and corresponding dismissals of blame. Such charges are contentious because the content and applicability conditions of anti-meddling norms can be difficult to specify. An unappreciated reason they can be contentious is that it is often not settled in advance whether some wrongdoing is or is not the business of a would-be

Higher-order metaphysicians take facts to be higher-order beings, i.e., entities in the range of irreducibly higher-order quantifiers. In this paper, I investigate the impact of this conception of facts on the debate about the reality of tense. I identify two major repercussions. The first concerns the logical space of tense realism: on a higher-order conception of facts, a prominent version of tense

Laws of nature are sometimes said to govern their instances. Spelling out what governance is, however, is an important task that has only recently received sustained philosophical attention. In the first part of this paper, I argue against the two prominent reductive views of governance—modal views and grounding views. Ruling out the promising candidates for reduction supports the claim that governance

What are credences? Where do the numbers come from? Some have argued that they are brute and primitive; others, that they model our dispositions to bet, our comparative confidence judgments, or our all-out beliefs. This paper explores a new answer to this question: credences model our dispositions to guess. I argue that we can think of credences this way, and then consider: should we?

Philosophers have argued that stakes affect knowledge: a given amount of evidence may suffice for knowledge if the stakes are low, but not if the stakes are high. By contrast, empirical work on the influence of stakes on ordinary knowledge ascriptions has been divided along methodological lines: “evidence-fixed” prompts rarely find stakes effects, while “evidence-seeking” prompts consistently find

Arithmetical pluralism is the view that there is not one true arithmetic but rather many apparently conflicting arithmetical theories, each true in its own language. While pluralism has recently attracted considerable interest, it has also faced significant criticism. One powerful objection, which can be extracted from Parsons (2008), appeals to a categoricity result to argue against the possibility

Moods, orthodoxy holds, exist outside the space of reasons. A depressed subject may change their thoughts and behaviors as a result of their depression. But, according to this view, their mood gives them no genuine reason to do so. Instead, moods are mere causal influences on cognition. The issue is that moods, with their diffuse phenomenology, appear to lack intentionality (Directionlessness). But

According to the modal account of luck it is a matter of luck that p if p is true at the actual world, but false in a wide-range of nearby worlds. According to the modal account of risk, it is risky that p if p is true at some close world. I argue that the modal accounts of luck and risk do not mesh well together. The views entail that p can be both maximally risky and maximally lucky, but there is

According to the principle of indifference, when a set of possibilities is evidentially symmetric for you – when your evidence no more supports any one of the possibilities over any other – you're required to distribute your credences uniformly among them. Despite its intuitive appeal, the principle of indifference is often thought to be unsustainable due to the problem of multiple partitions: Depending

This paper presents the epistemic practices account, a theory about the nature of epistemic normativity. The account aims to explain how the pursuit of epistemic values such as truth and knowledge can give rise to epistemic norms. On this account, epistemic norms are the internal rules of epistemic social practices. The account explains four crucial features of epistemic normativity while dissolving

The question whether the notion of rigidity can be extended in a fruitful way beyond singular terms has received a standard answer in the literature, according to which non‐singular terms designate kinds, properties or other abstract singular objects, and generalized rigidity is the same thing as singular term rigidity, but for terms designating such objects. I offer some new criticisms of this view

This paper examines the nature of the specific grasp involved in moral understanding. After discussing Hills's ability account of that central component of moral understanding in light of problematic cases, I argue that moral grasp is best conceived of as a type of knowledge that is grounded in a subject's moral appreciation. I then show how and why the relevant notion of moral appreciation is connected

A notable feature of our moral and legal practices is the recognition of privileges, powers, and entitlements belonging to a select group of individuals in virtue of their status as victims of wrongful conduct. A philosophical literature on relational normativity purports to account for this status in terms of such notions as interests, rights, and attitudes of disregard. This paper argues that such

Much has been written on whether practical knowledge (knowledge‐how) reduces to propositional knowledge (knowledge‐that). Less attention has been paid to what we call deliberative knowledge (knowledge‐to), i.e., knowledge ascriptions embedding other infinitival questions, like where to meet, when to leave, and what to bring. We offer an analysis of knowledge‐to and argue on its basis that, regardless

Doxastic involuntarism—the thesis that we lack direct voluntary control (in response to non‐evidential reasons) over our belief states—is often touted as philosophical orthodoxy. I here offer a novel defense of doxastic voluntarism, centered around three key moves. First, I point out that belief has two central functional roles, but that discussions of voluntarism have largely ignored questions of

Our universe seems to be miraculously fine‐tuned for life. Multiverse theories have been proposed as an explanation for this on the basis of probabilistic arguments, but various authors have objected that we should consider our total evidence that this universe in particular has life in our inference, which would block the argument. The debate thus crucially hinges on how Bayesian background and evidence

Let ‘semantic relevance’ be the thesis that the wide semantic properties of representational mental states (like beliefs and desires) are causally relevant to behavior. A popular way of arguing for semantic relevance runs as follows: start with a sufficient counterfactual condition for causal or explanatory relevance, and show that wide semantic properties meet it with respect to behavior (e.g., Loewer

What is it to know someone? Epistemologists rarely take up this question, though recent developments make such inquiry possible and desirable. This paper advances an account of how such interpersonal knowledge goes beyond mere propositional and qualitative knowledge about someone, giving a central place to second‐personal treatment. It examines what such knowledge requires, and what makes it distinctive

This paper examines the relationship between evidentialism, knowledge‐first epistemology, (E=K) in particular, and justification. Evidentialism gives an account of justified belief in terms of evidence but is silent on the nature of evidence. Knowledge‐first tells us what evidence is but stands in need of an agreed account of justification. So each might be able to supply what the other lacks. I argue

Frankfurt‐style action cases have been immensely influential in the free will and moral responsibility literatures because they arguably show that an agent can be morally responsible for a behavior despite lacking the ability to do otherwise. However, even among the philosophers who accept Frankfurt‐style action cases, there remains significant disagreement about whether also to accept Frankfurt‐style

It's often thought that when we reason to new judgments in inference, we aim at believing the truth, and that this aim of ours can explain important psychological and normative features of belief. I reject this picture: the structure of aimed activity shows that inference is not guided by a truth‐aim. This finding clears the way for a positive understanding of how epistemic goods feature in our doxastic

Explanatory metaphysics aspires to explain the less fundamental in terms of the more fundamental. But we should recognize two importantly different approaches to this task. According to the generation approach, more basic features of reality generate (or give rise to) less basic features. According to the reduction approach, less perspicuous ways of representing reality reduce to (or collapse into)
