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

The Gamer’s Dilemma refers to the philosophical challenge of justifying the intuitive difference people seem to see between the moral permissibility of enacting virtual murder and the moral impermissibility of enacting virtual child molestation in video games (Luck Ethics and Information Technology, 1:31, 2009). Recently, Luck in Philosophia, 50:1287–1308, 2022 has argued that the Gamer’s Dilemma is actually an instance of a more general “paradox”, which he calls the “paradox of treating wrongdoing lightly”, and he proposes a graveness resolution to (...) this paradox. In response, we argue for four key claims. First, we accept Luck’s expansion of the Gamer’s Dilemma to be applicable to a wider set of media, but give a novel recasting of this in terms of the Paradox of Fictionally Going Too Far. Second, we develop a novel criticism of Luck in Philosophia, 50:1287–1308, 2022 graveness resolution to this broader paradox. Third, we argue that the Paradox of Fictionally Going Too Far helps to expose an implicit moralism in the Gamer’s Dilemma literature when compared to relevant nearby literatures about other forms of media. Fourth, we consider a range of non-moral, cultural and media conventions that plausibly help to dissolve the intuitive moral gap between non-sexual and sexual violence that is central to this paradox.

In certain cases, people judge that agents bring about ends intentionally but also that they do not bring about the means that brought about those ends intentionally—even though bringing about the ends and means is just as likely. We call this difference in judgments the Kraemer effect. We offer a novel explanation for this effect: a perceived difference in the extent to which agents know how to bring about the means and the ends explains the Kraemer effect. In several experiments, (...) we replicate the Kraemer effect in a variety of non-moral and moral scenarios, and we find support for our new account. This work accords with a burgeoning area of action theory that identifies an important connection between know-how and intentionality. (shrink)

According to proponents of the extended mind, bio-external resources, such as a notebook or a smartphone, are candidate parts of the cognitive and mental machinery that realises cognitive states and processes. The present chapter discusses three areas of ethical concern associated with the extended mind, namely mental privacy, mental manipulation, and agency. We also examine the ethics of the extended mind from the standpoint of three general normative frameworks, namely, consequentialism, deontology, and virtue ethics.

Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks — from the way monkeys in a troop communicate, to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this paper, we argue there is a tension between how Skyrms talks of signalling networks and his (...) formal measure of information. Although Skyrms refers to both how information flows through networks and that signals carry information, we show that his formal measure only captures the latter. We then suggest that to capture the notion of flow in signalling networks, we need to treat them as causal networks. This provides the formal tools to define a measure that does capture flow, and we do so by drawing on recent work defining causal specificity. Finally, we suggest that this new measure is crucial if we wish to explain how evolution creates information. For signals to play a role in explaining their own origins and stability, they can’t just carry information about acts: they must be difference-makers for acts. (shrink)

The Gamer’s Dilemma is based on the intuitions that in single-player video games fictional acts of murder are seen as morally acceptable whereas fictional acts of sexual assault are seen as morally unacceptable. Recently, it has been suggested that these intuitions may apply across different forms of media as part of a broader Paradox of Fictionally Going Too Far. This study aims to empirically explore this issue by determining whether fictional murder is seen as more morally acceptable than fictional sexual (...) assault across different media types, and whether audio-visuality and the degree of agency afforded by the medium influences these judgments. An experimental survey study was developed where participants responded to imaginary fictional scenarios as part of a 2 (engages with fictional murder or fictional sexual assault) X 2 (in a high or low agency) X 2 (audio-visual or non-audio-visual medium) factorial design. It was found that fictional murder was seen to be more morally acceptable than fictional sexual assault across all media types, providing empirical support for the Paradox of Fictionally Going Too Far. It was also found that the audio-visuality and degree of agency influenced judgments of moral acceptability. (shrink)

We develop an approach to the problem of de se belief usually expressed with the question, what does the shopper with the leaky sugar bag have to learn to know that s/he is the one making the mess. Where one might have thought that some special kind of “de se” belief explains the triggering of action, we maintain that this gets the order of explanation wrong. We sketch a very simple cognitive architecture that yields de se-like behavior on which the (...) action-triggering functionality of the belief-state is what counts it as de se rather than some prior property of being “de se” explaining the triggering of action. This functionality shows that action-triggering change in belief-state also undergirds a correlative change in the objective involved in the triggered action. This model is far too simple to have any claim to showing how the de se works for humans, but it shows, by illustration, that nothing mysteriously “subjective”” need be involved in this aspect of self-conception. While our exposition is very different from those of Perry and Recanati, all three of us are developing the same kind of view. (shrink)

Placebos are often used by clinicians, usually deceptively and with little rationale or evidence of benefit, making their use ethically problematic. In contrast with their typical current use, a provocative line of research suggests that placebos can be intentionally exploited to extend analgesic therapeutic effects. Is it possible to extend the effects of drug treatments by interspersing placebos? We reviewed a database of placebo studies, searching for studies that indicate that placebos given after repeated administration of active treatments acquire medication-like (...) effects. We found a total of 22studies in both animals and humans hinting of evidence that placebos may work as a sort of dose extender of active painkillers. Wherever effective in relieving clinical pain, such placebo use would offer several advantages. First, extending the effects of a painkiller through the use of placebos may reduce total drug intake and side effects. Second, dose-extending placebos may decrease patient dependence. Third, using placebos along with active medication, for part of the course of treatment, should limit dose escalation and lower costs. Importantly, provided that nondisclosure is pre-authorized in the informed consent process and that robust evidence indicates therapeutic benefit comparable to that of standard full-dose therapeutic regimens, introducing dose-extending placebos into the clinical arsenal should be considered. This novel prospect of placebo use has the potential to change our general thinking about painkiller treatments, the typical regimens of painkiller applications, and the ways in which treatments are evaluated.

This paper investigates whether practical interests affect knowledge attributions in cases of testimony. It is argued that stakes impact testimonial knowledge attributions by increasing or decreasing the requirements for hearers to trust speakers and thereby gain the epistemic right to acquire knowledge via testimony. Standard, i.e. invariantist, reductionism and non-reductionism fail to provide a plausible account of testimony that is stakes sensitive, while non- invariantist versions of both traditional accounts can remedy this deficiency. Support for this conceptual analysis of stakes (...) is found through a review of the experimental philosophy literature on stakes effects on knowledge attribution. Finally, a diagnosis is offered for what is needed to provide a more robust defense of the paper’s primary claims in terms of future experimental study. (shrink)

This thesis is primarily an attempt at solving some issues in Schopenhauer’s theory of salvation. My aim is to provide ways in which Schopenhauer’s soteriology could work. It is a partially reconstructive project in that I will be bringing to the forefront some of Schopenhauer’s assertions at the expense of others. My aim is to show that we are able to provide a much more cohesive and satisfying reading of Schopenhauer’s philosophical project if we let go of some of the (...) more orthodox assumptions in the Schopenhauer scholarship – chief amoung these being that Schopenhauer is committed to the view that the will constitutes ultimate reality. While this reading is a departure from the vast majority of the traditional readings of Schopenhauer’s philosophy, I believe it has the twin advantages of both aligning Schopenhauer’s thought much closer with the eastern traditions he believes his work is in sympathy with, and ultimately, providing a new platform from which to assess the ‘traditional’ reading of Schopenhauer’s thought as ‘hopelessly pessimistic’. It is my contention that while it remains true that Schopenhauer is very much a pessimist about the world as manifested will, it is the perceived difficulties of his philosophy of salvation that have provided the most significant road block preventing critics from seeing that there are dimensions to Schopenhauer’s thought that cannot so easily be labelled as either pessimistic or optimistic. This thesis is an attempt to shed light on possible new readings of Schopenhauer’s project in light of attempts to resolve issues in his soteriology. I begin with the question – why do we need saving? I attempt to answer this through an analysis of the terms ‘will’, ‘will-to-life’ and ‘affirmation and negation of the will-to-life’. Next, I attempt to argue that the will should not be seen as ultimate reality in Schopenhauer’s system and that this is both closer to the account which Schopenhauer himself was inclining towards later in his writings as well asa necessary sacrifice in order to save Schopenhauer from more problematic inconsistencies. I next attempt to solve inconsistencies in Schopenhauer’s account of personal identity. I argue that there can only be a denial of the will-to-life if there is more to our identity than willing. I will also examine the possibility of a denial of the will-to-life at all. I will be engaging with recent scholarship from Christopher 3 Janaway on the possibility of negating the will-to-life and the implications of this for Schopenhauer’s account of willing. I will then attempt to resolve the on-going debate in the secondary literature concerning Schopenhauer’s ethical pronouncements and his theory of the negation of the will-to-life. I will argue, contrary to Sandra Shapshay and Tristan Ferrell, that it is possible to be one in whom the will has denied itself while remaining one who wills ethically and that this can be the case if we focus our attention on what Schopenhauer may truly mean by a compassionate will to help others. Next, I will be asking why exactly it is good to be one in whom the will has denied itselfand what this means for our understanding of value for the will-less subject. Finally, I will be focusing on Schopenhauer’s pessimism and how a new reading of Schopenhauer’s soteriology means that we can introduce new ways of assessing both the world as well as the place of Schopenhauer’s philosophical system within it. Ultimately, I will conclude that any interpretation of Schopenhauer’s philosophy presents the scholar with a choice and that we are subsequently only able to make new evaluative assessments on Schopenhauer’s philosophy, as well push back against the charge that it is wholly pessimistic, if we choose to accept major revisions to his metaphysics of the will. However, because Schopenhauer himself seemed to be moving towards such revisions, we should not be afraid of doing so either. (shrink)

In this article, seven strategies for dealing with cross-cultural ethical conflict are described. Conflict situations are classified on the basis of centrality and consensus on the values involved, influence of the decision maker, and urgency. A contingency model suggests appropriate strategies for different situations. The model is applied to representative cases of cross-cultural ethical conflict.

In this paper, I explore a tension between the Law in the novel The Island of Doctor Moreau, by H. G. Wells, and Kant's reciprocity thesis. The Law is a series of prohibitions that Moreau has his beasts recite. Moreau devotes his time to transforming animals through a painful surgery into beings that resemble humans, but the humanized beasts are constantly slipping back into animalistic habits, and so Moreau promulgates the Law to maintain decorum. Kant's reciprocity thesis states that free (...) will is the necessary and sufficient condition of moral practical laws. That is, in order for a moral practical law to be applicable, there must be free will, and, if free will is present, then there will be a moral practical law that sets a standard for the free will. However, in Wells's novel, the humanized beasts seem to lack free will. So, how can a law be applicable to them? By delving deeper into the mystery of Moreau's strange island, I will shed light on the otherwise cumbersome concepts of free will, natural impulses, and practical laws, as well as their interrelationships. The upshot will be a deeper understanding of personhood through an exploration of the instinctual nature of animals, moral law, and free will. (shrink)

In this chapter, we analyze the relationships between the Internet and its users in terms of situated cognition theory. We first argue that the Internet is a new kind of cognitive ecology, providing almost constant access to a vast amount of digital information that is increasingly more integrated into our cognitive routines. We then briefly introduce situated cognition theory and its species of embedded, embodied, extended, distributed and collective cognition. Having thus set the stage, we begin by taking an embedded (...) cognition view and analyze how the Internet aids certain cognitive tasks. After that, we conceptualize how the Internet enables new kinds of embodied interaction, extends certain aspects of our embodiment, and examine how wearable technologies that monitor physiological, behavioral and contextual states transform the embodied self. On the basis of the degree of cognitive integration between a user and Internet resource, we then look at how and when the Internet extends our cognitive processes. We end this chapter with a discussion of distributed and collective cognition as facilitated by the Internet. (shrink)

Some ‘naturalist’ accounts of disease employ a biostatistical account of dysfunction, whilst others use a ‘selected effect’ account. Several recent authors have argued that the biostatistical account offers the best hope for a naturalist account of disease. We show that the selected effect account survives the criticisms levelled by these authors relatively unscathed, and has significant advantages over the BST. Moreover, unlike the BST, it has a strong theoretical rationale and can provide substantive reasons to decide difficult cases. This is (...) illustrated by showing how life-history theory clarifies the status of so-called diseases of old age.

People generally accept that there is causation by omission—that the omission of some events cause some related events. But this acceptance elicits the selection problem, or the difficulty of explaining the selection of a particular omissive cause or class of causes from the causal conditions. Some theorists contend that dependence theories of causation cannot resolve this problem. In this paper, we argue that the appeal to norms adequately resolves the selection problem for dependence theories, and we provide novel experimental evidence (...) for it. (shrink)

In the replies to my critics that follow I offer a more detailed account of the specific papers that they discuss or examine. The papers that they are especially concerned with are: “The Material World and Natural Religion in Hume’s Treatise” (Ryan) [Essay 3], “Hume’s Skepticism and the Problem of Atheism” (Fosl) [Essay 12], and “Hume’s Philosophy of Irreligion and the Myth of British Empiricism (Gautier) [Essay 16].

Recasting Hume and Early Modern Philosophy is a collection of essays that are all concerned with major figures and topics in the early modern philosophy. Most of the essays are concerned, more specifically, with the philosophy of David Hume (1711-1776). The sixteen essays included in this collection are divided into five parts. These parts are arranged under the headings of: (1) Metaphysics and Epistemology; (2) Free Will and Moral Luck; (3) Ethics, Virtue and Optimism; (4) Skepticism, Religion and Atheism; and (...) (5) Irreligion and the Unity of Hume’s Thought. A particularly important theme running through many of these essays is the subject of Hume’s irreligious aims and intentions. The fifth and final part of the collection is devoted to an articulation and defence of this specific understanding of Hume’s philosophical thought. (shrink)

I provide a novel knowledge-first account of justification that avoids the pitfalls of existing accounts while preserving the underlying insight of knowledge-first epistemologies: that knowledge comes first. The view I propose is, roughly, this: justification is grounded in our practical knowledge (know-how) concerning the acquisition of propositional knowledge (knowledge-that). I first refine my thesis in response to immediate objections. In subsequent sections I explain the various ways in which this thesis is theoretically superior to existing knowledge-first accounts of justification. The (...) upshot is a virtue-theoretic, knowledge-first view of justification that is internalist-friendly and able to explain more facts about justification than any other available view. (shrink)

According to political liberalism, laws must be justified to all citizens in order to be legitimate. Most political liberals have taken this to mean that laws must be justified by appeal to a specific class of ‘public reasons’, which all citizens can accept. In this paper I defend an alternative, convergence, model of public justification, according to which laws can be justified to different citizens by different reasons, including reasons grounded in their comprehensive doctrines. I consider three objections to such (...) an account—that it undermines sincerity in public reason, that it underestimates the importance of shared values, and that it is insufficiently deliberative—and argue that convergence justifications are resilient to these objections. They should therefore be included within a theory of political liberalism, as a legitimate form of public justification. This has important implications for the obligations that political liberalism places upon citizens in their public deliberations and reason-giving, and might make the theory more attractive to some of its critics, particularly those sympathetic to religious belief.

According to many, to have epistemic justification to believe P is just for it to be epistemically permissible to believe P. Others think it is for believing P to be epistemically good. Yet others think it has to do with being epistemically blameless in believing P. All such views of justification encounter problems. Here, a new view of justification is proposed according to which justification is a kind of composite normative status. The result is a view of justification that offers (...) hope of solving some longstanding epistemological problems. (shrink)

In attempting to form rational personal probabilities by direct inference, it is usually assumed that one should prefer frequency information concerning more specific reference classes. While the preceding assumption is intuitively plausible, little energy has been expended in explaining why it should be accepted. In the present article, I address this omission by showing that, among the principled policies that may be used in setting one’s personal probabilities, the policy of making direct inferences with a preference for frequency information for (...) more specific reference classes yields personal probabilities whose accuracy is optimal, according to all proper scoring rules, in situations where all of the relevant frequency information is point-valued. Assuming that frequency information for narrower reference classes is preferred, when the relevant frequency statements are point-valued, a dilemma arises when choosing whether to make a direct inference based upon relatively precise-valued frequency information for a broad reference class, R, or upon relatively imprecise-valued frequency information for a more specific reference class, R*. I address such cases, by showing that it is often possible to make a precise-valued frequency judgment regarding R* based on precise-valued frequency information for R, using standard principles of direct inference. Having made such a frequency judgment, the dilemma of choosing between and is removed, and one may proceed by using the precise-valued frequency estimate for the more specific reference class as a premise for direct inference.

An argument for the eponymous conclusion is given through a series of hypothetical syllogisms, the most basic of which is as follows: morality is necessary for self-respect; self-respect is necessary for happiness; therefore, morality is necessary for happiness.

This essay critically assesses the central claim of Kevin Vallier’s Liberal Politics and Public Faith: that public religious faith and public reason liberalism can be reconciled, because the values underlying public reason liberalism should lead us to endorse the ‘convergence view’, rather than the mainstream consensus view. The convergence view is friendlier to religious faith, because it jettisons the consensus view’s much-criticised ‘duty of restraint’. I present several challenges to Vallier’s claim. Firstly, if Vallier is right to reject the duty (...) of restraint then consensus theorists can also do so, and on the same grounds. Secondly, the independent force of the objections to the duty of restraint is unclear. Thirdly, Vallier has not successfully identified desiderata that unite all public reason liberals and favour convergence over consensus. Finally, even if convergence is in some ways friendlier to religious faith, this does not show that it will be attractive to religious citizens. (shrink)

Continuing prior work by the author, a simple classical system for personal obligation is integrated with a fairly rich system for aretaic (agent-evaluative) appraisal. I then explore various relationships between definable aretaic statuses such as praiseworthiness and blameworthiness and deontic statuses such as obligatoriness and impermissibility. I focus on partitions of the normative statuses generated ("normative positions" but without explicit representation of agency). In addition to being able to model and explore fundamental questions in ethical theory about the connection between (...) blame, praise, permissibility and obligation, this allows me to carefully represent schemes for supererogation and kin. These controversial concepts have provided challenges to both ethical theory and deontic logic, and are among deontic logic's test cases. (shrink)

Some environmental ethicists and economists argue that attributing infinite value to the environment is a good way to represent an absolute obligation to protect it. Others argue against modelling the value of the environment in this way: the assignment of infinite value leads to immense technical and philosophical difficulties that undermine the environmentalist project. First, there is a problem of discrimination: saving a large region of habitat is better than saving a small region; yet if both outcomes have infinite value, (...) then decision theory prescribes indifference. Second, there is a problem of swamping probabilities: an act with a small but positive probability of saving an endangered species appears to be on par with an act that has a high probability of achieving this outcome, since both have infinite expected value. Our paper shows that a relative concept of infinite value can be meaningfully defined, and provides a good model for securing the priority of the natural environment while avoiding the failures noted by sceptics about infinite value. Our claim is not that the relative infinity utility model gets every detail correct, but rather that it provides a rigorous philosophical framework for thinking about decisions affecting the environment.

Distributive justice, defined as justice in distribution of income and wealth, is impossible. Income and wealth are distributed either unequally or equally. If unequally, then those with less are unjustly subject to social contempt. But equal distribution is impossible because it is inconsistent with bargaining to advance our own good. Hence justice in distribution of income and wealth is impossible. More generally, societies where social relations are mediated by money are necessarily unjust, and Marx was wrong to think a socialist (...) society which retained money would lead to communism. Contributive justice proposes that each flourishes by advancing the flourishing of others. To achieve this goal all labor, both simple and complex, must be shared among all capable of doing it. The good of contributing our abilities to benefit others is then available to all non-competitively. (shrink)

The present article illustrates a conflict between the claim that rational belief sets are closed under deductive consequences, and a very inclusive claim about the factors that are sufficient to determine whether it is rational to believe respective propositions. Inasmuch as it is implausible to hold that the factors listed here are insufficient to determine whether it is rational to believe respective propositions, we have good reason to deny that rational belief sets are closed under deductive consequences.

This paper focuses on Elizabeth Anderson’s application of the epistemological idiom of mētis to the debate over the equal status of indigenous knowledge and scientific knowledge in the academic curriculum. Against the denial of this equal status by critics of indigenous knowledge or science, Anderson defends what one might term a conciliatory view, the view, roughly, that indigenous knowledge meets the criteria of scientific knowledge presupposed by the critics of the equal status of indigenous knowledge and scientific knowledge in the (...) academic curriculum, and it is continuous with agroecological form of mainstream scientific inquiry. I argue that the conciliatory view does not rest substantively on mētis as an epistemological idiom since the view is based on the direct conceptual relation between the notion of indigenous knowledge and the notion of scientific knowledge or inquiry. More importantly, the view amounts to appealing to the critics of the equal status of indigenous knowledge on the terms of those critics and leaves unchallenged those very core assumptions that ground their denial of the equal status of indigenous knowledge in the first place. Building on her fruitful analysis of mētis, I attempt a sketch of an alternative view that vindicates the equal status of indigenous knowledge and scientific knowledge in the academic curriculum, but which avoids those drawbacks.

Should a principle of charity be applied to the interpretation of the colour concepts exercised in visual experience? We think not. We shall argue, for one thing, that the grounds for applying a principle of charity are lacking in the case of colour concepts. More importantly, we shall argue that attempts at giving the experience of colour a charitable interpretation either fail to respect obvious features of that experience or fail to interpret it charitably, after all. Charity to visual experience (...) is therefore no motive for resisting the natural, Galilean response to a scientific understanding of light and vision. The best interpretation of colour experience ends up convicting it of widespread and systematic error. (shrink)

We present a cosmological model (RL+) that offers exact predictions for the Hubble constant, the cosmological constant, the total energy density of the universe, and a curvature that matches current observational constraints. The model predicts a cosmological constant energy density that constitutes approximately 64% of the total energy budget, in agreement with current estimates from the standard LCDM model. Furthermore, the model addresses several longstanding cosmological problems—namely, the problem of infinite initial density, the coincidence problem, and the flatness problem—all with (...) the introduction of a single temporal parameter.

This paper develops a trivalent semantics for the truth conditions and the probability of the natural language indicative conditional. Our framework rests on trivalent truth conditions first proposed by Cooper (1968) and Belnap (1973) and it yields two logics of conditional reasoning: (i) a logic C of certainty-preserving inference; and (ii) a logic U for uncertain reasoning that preserves the probability of the premises. We show systematic correspondences between trivalent and probabilistic representations of inferences in either framework, and we use (...) the distinction between the two systems to cast light on the validity of inferences such as Modus Ponens, Or-To-If, and Conditional Excluded Middle. Specifically, the conditional behaves monotonically in C, but non-monotonically in U; Modus Ponens is valid in C, but valid in U only for non-nested conditionals. The result is a unified account of the semantics and epistemology of indicative conditionals that can be fruitfully applied to analyzing the validity of conditional inferences. (shrink)

In previous work, we studied four well known systems of qualitative probabilistic inference, and presented data from computer simulations in an attempt to illustrate the performance of the systems. These simulations evaluated the four systems in terms of their tendency to license inference to accurate and informative conclusions, given incomplete information about a randomly selected probability distribution. In our earlier work, the procedure used in generating the unknown probability distribution (representing the true stochastic state of the world) tended to yield (...) probability distributions with moderately high entropy levels. In the present article, we present data charting the performance of the four systems when reasoning in environments of various entropy levels. The results illustrate variations in the performance of the respective reasoning systems that derive from the entropy of the environment, and allow for a more inclusive assessment of the reliability and robustness of the four systems.

Generative AI technologies have the potential to be socially and politically transformative. In this paper, we focus on exploring the potential impacts that Generative AI could have on the functioning of our democracies and the nature of citizenship. We do so by drawing on accounts of deliberative democracy and the deliberative virtues associated with it, as well as the reciprocal impacts that social media and Generative AI will have on each other and the broader information landscape. Drawing on this background (...) theory, we outline some of the key positive and negative impacts that Generative AI is likely to have on democratic citizenship. The political significance of these impacts suggests the need for further regulation. (shrink)

It is one thing to hold that merely statistical evidence is _sometimes_ insufficient for rational belief, as in typical lottery and profiling cases. It is another thing to hold that merely statistical evidence is _always_ insufficient for rational belief. Indeed, there are cases where statistical evidence plainly does justify belief. This project develops a dispositional account of the normativity of statistical evidence, where the dispositions that ground justifying statistical evidence are connected to the goals (= proper function) of objects. There (...) are strong intuitive motivations for doing this. For we can turn almost any case of _non-justifying_ merely statistical evidence into a case of _justifying_ merely statistical evidence by adding information about the dispositions and goals of the objects involved. The resulting view not only helps us understand when and why merely statistical evidence is normatively significant, but it also helps us understand how statistical evidence relates to more standard forms of evidence (perceptual, testimonial). The emerging view also has surprising applications, as it imposes limitations on the epistemic value of fine-tuning arguments for theism as well as undermines a standard class of case-based arguments for moral encroachment.

Sainsbury argued that exact extensions for predicates entails the unacceptable infinite tower of higher order vagueness so that exact extensions must be rejected. I offer a second argument: The exact extensions arise when semantic values are assumed to be (exact) properties. But no assignment of unique properties to predicates could arise from any real-world finite basis. How, then, is talk of properties as semantic values to be understood? We distinguish the precise compositional rules of semantics from the operation of messy, (...) imprecise rules at the word/world interface for applicability of minimal predicates. When such application is sufficiently clear it is idealized as property instantiation and semantic composition proceeds in familiar ways. These imprecise rules for application of minimal predicates provide the proper locus for study of vagueness. The conclusions thus far apply to show that higher order vagueness is not forced and that classical logic can generally be retained. I discuss implications for the sorites paradox. Abandoning properties entails abandoning simple correspondence truth understood as Pa is true just in case a has the property signified by P. As an alternative I outline a pragmatist approach to truth, the spirit of which is conveyed by the slogan, “To be true enough is to work well enough.”. (shrink)

Descartes’s cogito – I am thinking, therefore I am – is an intuitive deduction. Contrary to Transparency, certainty of I am thinking does not come easily; it’s achieved by making introspection perfectly clear through radical doubt.

Proponents of public reason views hold that the exercise of political power ought to be acceptable to all reasonable citizens. This article elucidates the common structure shared by all public reason views, first by identifying a set of questions that all such views must answer and, second, by showing that the answers to these questions stand in a particular relationship to each other. In particular, we show that what we call the ‘rationale question’ is fundamental. This fact, and the common (...) structure more generally, are often overlooked or distorted within the literature. As a result, we argue, several prominent argumentative moves made by both critics and defenders of public reason are unsuccessful. Our overall conclusion is that discussions of public reason views would be more fruitful if they made consistent use of the common structure we identify. (shrink)

It seems natural to choose whether to have a child by reflecting on what it would be like to actually have a child. I argue that this natural approach fails. If you choose to become a parent, and your choice is based on projections about what you think it would be like for you to have a child, your choice is not rational. If you choose to remain childless, and your choice is based upon projections about what you think it (...) would be like for you to have a child, your choice is not rational. This suggests we should reject our ordinary conception of how to make this life-changing decision, and raises general questions about how to rationally approach important life choices. (shrink)

Many of our most important goals require months or even years of effort to achieve, and some never get achieved at all. As social psychologists have lately emphasized, success in pursuing such goals requires the capacity for perseverance, or "grit." Philosophers have had little to say about grit, however, insofar as it differs from more familiar notions of willpower or continence. This leaves us ill-equipped to assess the social and moral implications of promoting grit. We propose that grit has an (...) important epistemic component, in that failures of perseverance are often caused by a significant loss of confidence that one will succeed if one continues to try. Correspondingly, successful exercises of grit often involve a kind of epistemic resilience in the face of failure, injury, rejection, and other setbacks that constitute genuine evidence that success is not forthcoming. Given this, we discuss whether and to what extent displays of grit can be epistemically as well as practically rational. We conclude that they can be (although many are not), and that the rationality of grit will depend partly on features of the context the agent normally finds herself in. In particular, grit-friendly norms of deliberation might be irrational to use in contexts of severe material scarcity or oppression. (shrink)
