A long-standing debate in group ontology and group epistemology concerns whether some groups possess mental states and/or epistemic states such as knowledge that do not reduce to the mental states and/or epistemic states of the individuals who comprise such groups (and are also states not possessed by any of the members). Call those who think there are such states inflationists. There has recently been a defense in the literature of a specific type of inflationary knowledge—viz., knowledge of facts about group (...) minds or group self-knowledge (GS-K). In this paper I address whether some groups do possess such knowledge. I argue that we have good reason to think they do not. I do so by exploring the most explicit defense of such knowledge in the literature—Lukas Schwengerer’s (2022) defense—as well as other ways of defending this thesis and arguing that such ways are problematic. In the latter part of the paper, I explain why the two most popular inflationary approaches to group knowledge simpliciter are incompatible with there being GS-K. In doing so I work to show why even inflationists should reject the view that there is inflationary group self-knowledge. (shrink)

I argue for two claims: that the ordinary English truth predicate is a gradable adjective and that truth is a property that comes in degrees. The first is a semantic claim, motivated by the linguistic evidence and the similarity of the truth predicate’s behavior to other gradable terms. The second is a claim in natural language metaphysics, motivated by interpreting the best semantic analysis of gradable terms as applied to the truth predicate. In addition to providing arguments for these two (...) claims, I draw out consequences for debates about deflationism and truth-based analyses of notions such as assertion and logical consequence.

This paper explores the relationship between Toni Morrison’s 1987 novel, Beloved, and F. W. J. Schelling’s 1813 draft of Ages of the World (Die Weltalter). It shows that Die Weltalter, contrary to much recent scholarship, which often stresses the many ways Schelling anticipated the antimetaphysical trends of post-Hegelian thought, should be first approached as a genuine attempt tobe faithful to the event of first creation and time’s “indivisible remainders”. The paper will show that Schelling’s “indivisible remainders”, the forgotten and “disremembered” (...) of history, force his thought to the limits of Romantic and idealist reflection and toward the traumatic encounters of Beloved. Morrison’s depiction of the irrepressible longing for life and recognition amid the pain and ugliness of American slavery parallels Schelling’s efforts to understand the tremendous need for life and fellowship that first urged god toward creation, when primordial longing was overcome in a child and a god entered time.

Our relationship to the infinite is controversial. But it is widely agreed that our powers of reasoning are finite. I disagree with this consensus; I think that we can, and perhaps do, engage in infinite reasoning. Many think it is just obvious that we can't reason infinitely. This is mistaken. Infinite reasoning does not require constructing infinitely long proofs, nor would it gift us with non-recursive mental powers. To reason infinitely we only need an ability to perform infinite inferences. I (...) argue that we have this ability. My argument looks to our best current theories of inference and considers examples of apparent infinite reasoning. My position is controversial, but if I'm right, our theories of truth, mathematics, and beyond could be transformed. And even if I'm wrong, a more careful consideration of infinite reasoning can only deepen our understanding of thinking and reasoning. -/- (Note for readers: the paper's brief discussion of uniform reflection and omega inconsistency is misleading. The imagined interlocutor's argument makes an assumption about the PA-provability of provability generalizations that, while true for the Godel sentence's instances, is unjustified, in general. This means my position is stronger against this objection than the paper suggests, since omega inconsistent theories are not automatically inconsistent with their uniform reflection principles, you also need to assume the arithmetically true Pi-2 sentences.).

The ongoing debate within neuroethics concerning the degree to which neuromodulation such as deep brain stimulation (DBS) changes the personality, identity, and agency (PIA) of patients has paid relatively little attention to the perspectives of prospective patients. Even less attention has been given to pediatric populations. To understand patients’ views about identity changes due to DBS in obsessive-compulsive disorder (OCD), the authors conducted and analyzed semistructured interviews with adolescent patients with OCD and their parents/caregivers. Patients were asked about projected impacts (...) to PIA generally due to DBS. All patient respondents and half of caregivers reported that DBS would impact patient self-identity in significant ways. For example, many patients expressed how DBS could positively impact identity by allowing them to explore their identities free from OCD. Others voiced concerns that DBS-related resolution of OCD might negatively impact patient agency and authenticity. Half of patients expressed that DBS may positively facilitate social access through relieving symptoms, while half indicated that DBS could increase social stigma. These views give insights into how to approach decision-making and informed consent if DBS for OCD becomes available for adolescents. They also offer insights into adolescent experiences of disability identity and “normalcy” in the context of OCD. (shrink)

Conceptual engineers sometimes say they want to change what our words mean. If a certain kind of externalism is true, it might be nearly impossible to do that. For some of the external factors that determine meaning, like metaphysical naturalness or past usage, are not within our power to change. And if we can’t change what determines meaning, then we can’t change meaning. I argue that, if this sort of externalism is true, then conceptual engineers didn’t want to change what (...) our words mean anyway. And if they did, they could always engineer externalism out of the language, or engineer a new sense of ‘meaning’ which could be changed. So the truth of externalism does not pose a threat to the possibility of conceptual engineering. (shrink)

What is the source of logical and mathematical truth? This book revitalizes conventionalism as an answer to this question. Conventionalism takes logical and mathematical truth to have their source in linguistic conventions. This was an extremely popular view in the early 20th century, but it was never worked out in detail and is now almost universally rejected in mainstream philosophical circles. Shadows of Syntax is the first book-length treatment and defense of a combined conventionalist theory of logic and mathematics. It (...) argues that our conventions, in the form of syntactic rules of language use, are perfectly suited to explain the truth, necessity, and a priority of logical and mathematical claims, as well as our logical and mathematical knowledge.

Psychoanalysis and Deconstruction: Freud's Psychic Apparatusdemonstrates the relevance of deconstructive thinking for the clinical practice of psychoanalysis. Arguing that deconstruction has been misrepresented as a form of literary theory or a philosophy of language, the book puts Derrida, Heidegger and others working in the tradition of deconstruction into dialogue with debates in the contemporary psychoanalytic field. Attempting to retrieve what was radical in Freud's portrayal of the mind as a machine, Jared Russell stresses the importance of psychoanalysis for an (...) understanding of the relationship between the human and its current hyper-technological environment. Interventions into contemporary debates address psychoanalytic concepts such as the nature of the clinical frame, the intersubjective dialogue, unconscious communication and the experience of time. Russell argues that deconstruction, and in particular Derrida's work, can anticipate and help clarify ongoing developments at the cutting edge of psychoanalysis today.

Distinguishing “business” concerns from “ethical” values is not only an unfruitful and meaningless task, it is also an impossible endeavor. Nevertheless, fruitless attempts to separate facts from values produce detrimental second-order effects, both for theory and practice, and should therefore be abandoned. We highlight examples of exemplary research that integrate economic and moral considerations, and point the way to a business ethics discipline that breaks new ground by putting ideas and narratives about businesstogetherwith ideas and narratives about ethics.

Quantifier variance holds that different languages can have unrestricted quantifier expressions that differ in meaning, where an expression is a “quantifier” just in case it plays the right inferential role. Several critics argued that J.H. Harris’s “collapse” argument refutes variance by showing that identity of inferential role is incompatible with meaning variance. This standard, syntactic collapse argument has generated several responses. More recently, Cian Dorr proved semantic collapse theorems to generate a semantic collapse argument against variance. The argument is significantly (...) different from standard collapse, so it requires a new response. Here I clarify and analyze the semantic collapse argument, and explain how variantists can and should respond to it. The paper also includes an appendix showing the difficulties of positing identity variance without quantifier variance. The argument in the appendix has yet to appear in print, but is familiar to specialists. (shrink)

In the mid twentieth century, logical positivists and many other philosophers endorsed a simple equation: something was necessary just in case it was analytic just in case it was a priori. Kripke’s examples of a posteriori necessary truths showed that the simple equation is false. But while positivist-style inferentialist approaches to logic and mathematics remain popular, there is no inferentialist account of necessity a posteriori. I give such an account. This sounds like an anti-Kripkean project, but it is not. Some (...) of Kripke’s remarks even suggest this kind of approach. This inferentialist approach reinstates neither the simple equation nor pure conventionalism about necessity a posteriori. But it does lead to something near enough, a type of impure conventionalism. In recent years, metaphysically heavyweight approaches to modality have been popular, while other approaches have lagged behind. The inferentialist, impure conventionalist theory of necessity I describe aims to provide a metaphysically lightweight option in modal metaphysics. (shrink)

Like other epistemic activities, inquiry seems to be governed by norms. Some have argued that one such norm forbids us from believing the answer to a question and inquiring into it at the same time. But another, hither-to neglected norm seems to permit just this sort of cognitive arrangement when we seek to confirm what we currently believe. In this paper, I suggest that both norms are plausible and that the conflict between them constitutes a puzzle. Drawing on the felicity (...) conditions of confirmation requests and the biased interrogatives used to perform them, I argue that the puzzle is genuine. I conclude by considering a response to the puzzle that has implications for the debate regarding the relationship between credences and beliefs. (shrink)

Wandering is a symptom of dementia that can have devastating consequences on the lives of persons living with dementia and their families and caregivers. Increasingly, caregivers are turning towards electronic tracking devices to help manage wandering. Ethical questions have been raised regarding these location-based technologies and although qualitative research has been conducted to gain better insight into various stakeholders' views on the topic, developers of these technologies have been largely excluded. No qualitative research has focused on developers’ perceptions of ethics (...) related to electronic tracking devices. To address this, we performed a qualitative semi-structured interview study based on grounded theory. We interviewed 15 developers of electronic tracking devices to better understand how they perceive ethical issues surrounding the design, development, and use of these devices within dementia care. Our results reveal that developers are strongly motivated by moral considerations and believe that including stakeholders throughout the development process is critical for success. Developers felt a strong sense of moral obligation towards topics within their control and a weaker sense of moral obligation towards topics outside their control. This leads to a perceived moral boundary between development and use, where some moral responsibility is shifted to end-users. (shrink)

Conceptual engineers have recently turned to the notion of conceptual functions to do a variety of explanatory work. Functions are supposed to explain what speakers are debating about in metalinguistic negotiations, to capture when two concepts are about the same thing, and to help guide our normative inquiries into which concepts we should use. In this paper, I argue that this recent “functional turn” should be deflated. Contra most interpreters, we should not try to use a substantive notion of conceptual (...) functions to handle various problems for conceptual engineering. The primary accounts of function appealed to by conceptual engineers, namely etiological and system functions, are not suited to handle many of the problems functions are supposed to handle, and it’s dubious whether any other account of function would do better. Instead of trying to use substantive functions to solve theoretical problems, we should deflate those problems themselves by focusing only on what matters to us, as speakers or theorists, in a given inquiry.

Putting feelings into words, or “affect labeling,” can attenuate our emotional experiences. However, unlike explicit emotion regulation techniques, affect labeling may not even feel like a regulatory process as it occurs. Nevertheless, research investigating affect labeling has found it produces a pattern of effects like those seen during explicit emotion regulation, suggesting affect labeling is a form of implicit emotion regulation. In this review, we will outline research on affect labeling, comparing it to reappraisal, a form of explicit emotion regulation, (...) along four major domains of effects—experiential, autonomic, neural, and behavioral—that establish it as a form of implicit emotion regulation. This review will then speculate on possible mechanisms driving affect labeling effects and other remaining unanswered questions. (shrink)

In recent years, the e ffort to formalize erotetic inferences (i.e., inferences to and from questions) has become a central concern for those working in erotetic logic. However, few have sought to formulate a proof theory for these inferences. To fill this lacuna, we construct a calculus for (classes of) sequents that are sound and complete for two species of erotetic inferences studied by Inferential Erotetic Logic (IEL): erotetic evocation and regular erotetic implication. While an attempt has been made to (...) axiomatize the former in a sequent system, there is currently no proof theory for the latter. Moreover, the extant axiomatization of erotetic evocation fails to capture its defeasible character and provides no rules for introducing or eliminating question-forming operators. In contrast, our calculus encodes defeasibility conditions on sequents and provides rules governing the introduction and elimination of erotetic formulas. We demonstrate that an elimination theorem holds for a version of the cut rule that applies to both declarative and erotetic formulas and that the rules for the axiomatic account of question evocation in IEL are admissible in our system.

Previous studies found similarities in adults’ disgust responses to benign (e.g. obesity) and actual disease signs (e.g. influenza). However, limited research has compared visual (i.e. benign and actual) to cognitive (i.e. disease label) disease cues in different age groups. The current study investigated disgust responses across middle childhood (7–9 years), late childhood (10–12 years), adolescence (13–17 years), and adulthood (18+ years). Participants viewed individuals representing a benign visual disease (obese), sick-looking (staphylococcus), sick-label (cold/flu), and healthy condition. Disgust-related outcomes were: (1) (...) avoidance, or contact level with apparel the individual was said to have worn, (2) disgust facial reactions, and (3) a combination of (1) and (2). Avoidance was greater for the sick-looking and sick-label than the healthy and obese conditions. For facial reaction and combination outcomes, middle childhood participants responded with greater disgust to the sick-looking than the healthy condition, while late childhood participants expressed stronger disgust towards the sick-looking and obese conditions than the healthy condition. Adolescents and adults exhibited stronger disgust towards sick-label and sick-looking than obese and healthy conditions. Results suggest visual cues are central to children’s disgust responses whereas adolescents and adult responses considered cognitive cues. (shrink)

Several recent epistemologists have used understanding-assent links in theories of a priori knowledge and justification, but Williamson influentially argued against the existence of such links. Here I (1) clarify the nature of understanding-assent links and their role in epistemology; (2) clarify and clearly formulate Williamson’s arguments against their existence; (3) argue that Williamson has failed to successfully establish his conclusion; and (4) rebut Williamson’s claim that accepting understanding-assent links amounts to a form of dogmatism.

The study of defeasible reasoning unites epistemologists with those working in AI, in part, because both are interested in epistemic rationality. While it is traditionally thought to govern the formation and (with)holding of beliefs, epistemic rationality may also apply to the interrogative attitudes associated with our core epistemic practice of inquiry, such as wondering, investigating, and curiosity. Since generally intelligent systems should be capable of rational inquiry, AI researchers have a natural interest in the norms that govern interrogative attitudes. Following (...) its recent coinage, we use the term ``zetetic'' to refer to the properties and norms associated with the capacity to inquire. In this paper, we argue that zetetic norms can be modeled via defeasible inferences to and from questions---a.k.a erotetic inferences---in a manner similar to the way norms of epistemic rationality are represented by defeasible inference rules. We offer a sequent calculus that accommodates the unique features of ``erotetic defeat" and that exhibits the computational properties needed to inform the design of zetetic agents. The calculus presented here is an improved version of the one presented in Millson (2019), extended to cover a new class of defeasible erotetic inferences. (shrink)

Søren Kierkegaard is well-known as an original philosophical thinker, but less known is his reliance upon and development of the Christian tradition of the Seven Deadly Sins, in particular the vice of acedia, or sloth. As acedia has enjoyed renewed interest in the past century or so, commentators have attempted to pin down one or another Kierkegaardian concept (e.g., despair, heavy-mindedness, boredom, etc.) as the embodiment of the vice, but these attempts have yet to achieve any consensus. In our estimation, (...) the complicated reality is that, in using slightly different but related concepts, Kierkegaard is providing a unique look at acedia as it manifests differently at different stages on life’s way. Thus, on this “perspectival account”, acedia will manifest differently according to whether an individual inhabits the aesthetic, ethical, or religious sphere. We propose two axes for this perspectival account. Such descriptions of how acedia manifests make up the first, phenomenal axis, while the second, evaluative axis, accounts for the various bits of advice and wisdom we read in the diagnoses of acedia from one Kierkegaardian pseudonym to another. Our aim is to show that Kierkegaard was not only familiar with the concept of acedia, but his contributions helped to develop and extend the tradition. (shrink)

Daniel Dennett’s Consciousness Explained is probably the most widely read book about consciousness ever written by a philosopher. Despite this, the book has had a surprisingly small influence on how most philosophers of mind view consciousness. This might be because many philosophers badly misunderstand the book. They claim it does not even attempt to explain consciousness, but instead denies its very existence. Outside of philosophy the book has had more influence, but is saddled by the same misunderstanding. Now, 30 years (...) after publication, Consciousness Explained deserves reconsideration from anyone interested in consciousness. Here I make a case for this. To start, I will clear up the central misunderstanding of the book. With that done, I will explain and update Dennett’s tantalizing approach to consciousness and the mind. The result brings us very, very close to explaining consciousness. Or so I will argue. (shrink)

Public accounting firms must balance conflicting goals, including returning a profit for their owners (commercialism) and serving the public interest (professionalism). However, little is known about how these firms address this conflict and how it impacts financial performance. This study examines how accounting firms identify themselves in their mission statements through communicating their commercial or professional orientation. Our results suggest mission statements vary based on the service line from which accounting firms derive the majority of their revenue and firm size. (...) The mission statements of Tax and Management Advisory Services-dominant firms include more references to the commercial aspects of the public accounting enterprise, while Auditing and Accounting firms focus more on the professional aspects. Additionally, smaller (_larger_) firms are more likely to have mission statements that use language consistent with a professional (_commercial_) identity. We also find that commercialism-oriented components are positively associated with firm revenue growth and professionalism-oriented components are associated with lower revenue generation. We contribute to the mission statement literature by highlighting the association between mission statements and firm performance and to the accounting literature by providing empirical evidence of the role of mission statements in establishing the tone at the top of public accounting firms.

Achieving food system sustainability is one of the more pressing challenges of this century. Over the last decades, experts from diverse disciplines and intellectual traditions have worked to document the critical threats to food system sustainability and to define an appropriate agenda for action. Nevertheless, these efforts have tended to focus selectively on only a few components of the food system or have tended to be framed in particular discourses. Depending on the point of departure, what aspects of the food (...) system are considered threatened, and what must be sustained, can differ greatly between perspectives. In this article, we draw from systems-thinking and social-ecological systems concepts to focus on the underlying process-related attributes that could support a more sustainable food system. We then examine the support for specific system attributes in six different knowledge domains addressing sustainable agriculture and food. From this review, we identify five system attributes—diversity, modularity, transparency, innovation and congruence—that are repeatedly featured in the different knowledge domains as critical aspects of food system sustainability. We argue that in the face of considerable complexity and high uncertainty, these attributes can serve as a guide to conceptualizing food system choices adaptively and iteratively. (shrink)

By analyzing descriptions of illusory and nonillusory figures, Richer called into question the common assumption that illusory and nonillusory perceptions were experientially the same and differed only in terms of their accuracy. The present study attempted to replicate Richer's work with a focus on identifying within the subjects' descriptions any orienting attitudes corresponding to these two forms of perception. Nineteen student volunteers were asked to describe two illusory figures and a nonillusory control of similar complexity. The descriptions revealed consistent differences (...) between the two forms. However, the Hering and Zollner figures were not always described in illusory terms, and surprisingly, several subjects described the control as if it were illusory. Further, perceptual accuracy was not guaranteed by nonillusory experience. Subjects described the figures from within one of three different orienting attitudes-atomizing, representational, and geometrical-organizing. The latter attitude appeared necessary for the phenomena of illusory perception and experience. Though the present findings confirmed Richer's distinction between illusory and nonillusory experience, they also indicate the need for further differentiation- illusory perception versus illusory experience. Finally, the findings also supported Luria's and Segall, Campbell, and Herskovits's position on the importance of particular cultural and educational experiences and codes in relation to perceptual illusions.

This paper explores, analyzes, and investigates how the political ideologies of American citizens and their elected representatives interact with views put forth by corporate media to help shape various ideologies about environmental issues in contemporary America. I specifically enter into this area of exploration by focusing on one variable, the variable of religion. Therefore, in this paper I seek to help elucidate broad patterns and understandings of environmental issues in America as they have developed since the beginning of the modern (...) environmental movement, focusing especially on the role religion has and is playing in this process. The paper is driven by identifying two major groups in American society, Liberal/nurturant parent, and Conservative/strict father, and how the core values of each group influence their ideological approaches to religion, environmentalism, and politics. The investigation is undertaken in the larger context of worsening climate change, suggesting that the interplay of religious, political, and environmentalist ideology of the past few decades presages further ideological shifts in the coming decades about our changing biosphere.

The swamping problem is the problem of explaining why reliabilist knowledge (reliable true belief) has greater value than mere true belief. Swamping problem advocates see the lack of a solution to the swamping problem (i.e., the lack of a value-difference between reliabilist knowledge and mere true belief) as grounds for rejecting reliabilism. My aims here are (i) to specify clear requirements for a solution to the swamping problem that are as congenial to reliabilism's critics as possible, (ii) to clear away (...) various existing reliabilist solutions on the basis of these requirements, and (iii) to present a reliabilist solution that succeeds in meeting all of them. To meet all the requirements, my solution develops a more nuanced understanding of the epistemic end than is currently discussed, and with it a novel way of individuating beliefs. I close with a brief discussion of the question whether reliabilism's critics might impose further demands which reliabilism cannot possibly meet. (shrink)

Three studies tested the conditions under which people judge utilitarian harm to be authority dependent (i.e., whether its right or wrongness depends on the ruling of an authority). In Study 1, participants judged the right or wrongness of physical abuse when used as an interrogation method anticipated to yield useful information for preventing future terrorist attacks. The ruling of the military authority towards the harm was manipulated (prohibited vs. prescribed) and found to significantly influence judgments of the right or wrongness (...) of inflicting harm. Study 2 established a boundary condition with regards to the influence of authority, which was eliminated when the utility of the harm was definitely obtained rather than forecasted. Finally, Study 3 replicated the findings of Studies 1–2 in a completely different context—an expert committee’s ruling about the harming of chimpanzees for biomedical research. These results are discussed as they inform ongoing debates regarding the role of authority in moderating judgments of complex and simple harm. (shrink)

We show, relative to the base theory RCA₀: A nontrivial tree satisfies Ramsey's Theorem only if it is biembeddable with the complete binary tree. There is a class of partial orderings for which Ramsey's Theorem for pairs is equivalent to ACA₀. Ramsey's Theorem for singletons for the complete binary tree is stronger than $B\sum_{2}^{0}$ , hence stronger than Ramsey's Theorem for singletons for ω. These results lead to extensions of results, or answers to questions, of Chubb, Hirst, and McNicholl [3].

In ‘Patients, doctors and risk attitudes,’ Makins argues that, when physicians must decide for, or act on behalf of, their patients they should defer to patient risk attitudes for many of the same reasons they defer to patient values, although with a caveat: physicians should defer to the higher-order desires of patients when considering their risk attitudes. This modification of what Makins terms the ‘deference principle’ is primarily driven by potential counterexamples in which a patient has a first-order desire with (...) one risk attitude (either risk-seeking or averse) and a second-order desire that this risk attitude not be effective in guiding their choices.1 There are two reasons we might think people with obsessive–compulsive disorder (OCD) are particularly relevant patients for evaluating Makins’ proposal. Not only might their first-order risk attitudes be irrational, but many people with OCD also judge their own OCD behaviours to be excessive or unwarranted making them structurally similar to the counterexamples outlined above. Yet, I argue that recent research about risk and decision-making under uncertainty for those with OCD complicates Makins’ proposal by raising questions of whether and to what degree their risk attitudes are irrational such that they should not play a part in the surrogate decisions made by physicians. This places more …. (shrink)

Efforts to formalize qualitative accounts of inference to the best explanation (IBE) confront two obstacles: the imprecise nature of such accounts and the unusual logical properties that explanations exhibit, such as contradiction-intolerance and irreflexivity. This paper aims to surmount these challenges by utilising a new, more precise theory that treats explanations as expressions that codify defeasible inferences. To formalise this account, we provide a sequent calculus in which IBE serves as an elimination rule for a connective that exhibits many of (...) the properties associated with the behaviour of the English expression ‘That... best explains why ... ’. We first construct a calculus that encodes these properties at the level of the turnstile, i.e. as a metalinguistic expression for classes of defeasible consequence relations. We then show how this calculus can be conservatively extended over a language that contains a best-explains-why operator. (shrink)

In recent years, direct brain interventions have shown increased success in manipulating neurobiological processes often associated with moral reasoning and decision-making. As current DBIs are refined, and new technologies are developed, the state will have an interest in administering DBIs to criminal offenders for rehabilitative purposes. However, it is generally assumed that the state is not justified in directly intruding in an offender’s brain without valid consent. Thomas Douglas challenges this view. The state already forces criminal offenders to go to (...) jail without their consent. This represents a serious interference with an offender’s rights. If criminal offenders are already morally liable to incarceration, why is the state not also entitled to administer DBIs without consent for the purposes of rehabilitation? Douglas argument focuses on the right to ‘bodily integrity’. He argues that there is no compelling reason to believe that bodily rights that protect an offender from non-consensual DBIs are stronger than rights that protect an offender from incarceration. This paper will extend Douglas’ analysis. It will consider the more fundamental right to ‘mental integrity’. The right to mental integrity defends an inner sphere of liberty. It protects critical capacities necessary for the exercise of autonomous human agency—without which a vast majority of moral rights could not exist. Thus, the right to mental integrity is ultimately more important for a moral assessment of DBIs. The right strongly suggests that both presently, and in the future, there may be many cases in which the state is not entitled to administer DBIs to criminal offenders without valid consent.

Here I defend dispositionalism about meaning and rule-following from Kripkenstein's infamous anti-dispositionalist arguments. The problems of finitude, error, and normativity are all addressed. The general lesson I draw is that Kripkenstein's arguments trade on an overly simplistic version of dispositionalism.

A fascinating recent turn in epistemology focuses on inquiring attitudes like wondering and being curious. Many have argued that these attitudes are governed by norms similar to those that govern our doxastic attitudes. Yet, to date, this work has only considered norms that might *prohibit* having certain inquiring attitudes (``norms of restriction''), while ignoring those that might *require* having them (``norms of expansion''). We aim to address that omission by offering a framework that generates norms of expansion for inquiring attitudes. (...) The framework draws on inferential erotetic logic, which we explain and augment with some theorems. We explore several of the norms that it yields - some sympathetically, others unsympathetically.
