In this article I examine two mathematical definitions of observational equivalence, one proposed by Charlotte Werndl and based on manifest isomorphism, and the other based on Ornstein and Weiss’s ε-congruence. I argue, for two related reasons, that neither can function as a purely mathematical definition of observational equivalence. First, each definition permits of counterexamples; second, overcoming these counterexamples will introduce non-mathematical premises about the systems in question. Accordingly, the prospects for a broadly applicable and purely mathematical definition of observational (...) equivalence are unpromising. Despite this critique, I suggest that Werndl’s proposals are valuable because they clarify the distinction between provable and unprovable elements in arguments for observational equivalence.

Without directly addressing the Demarcation Problem for logic—the problem of distinguishing logical vocabulary from others—we focus on distinctive aspects of logical vocabulary in pursuit of a second goal in the philosophy of logic, namely, proposing criteria for the justification of logical rules. Our preferred approach has three components. Two of these are effectively Belnap’s, but with a twist. We agree with Belnap’s response to Prior’s challenge to inferentialist characterisations of the meanings of logical constants. Belnap argued that for a logical (...) constant to exist, its rules must be conservative over a previously given consequence relation and guarantee the uniqueness of the constant. The twist is that we require logical vocabulary to be provably conservative, not over a previously given formal consequence relation, but over a previously given meaningful vocabulary of a language. Uniqueness is also a feature defined in terms of provability: if two syntactically distinguished expressions are governed by the same rules, then formulas with them as main operators are interderivable. Belnap’s criteria are not only those for the existence of a logical constant, but more: they are what distinguishes logical vocabulary from all other expressions. It is the defining mark of a logical constant that it is provably conservative over the fragment of the language which excludes it and that its rules guarantee its uniqueness. The third component is the topic neutrality of logic. The provable conservativeness of logic over a previously given vocabulary of a language is motivated, in part, by appeal to molecularism in the theory of meaning. Molecularity is a feature endorsed by the theory of meaning as a whole, so it does not distinguish logical constants from other expressions. The same is true for conservativeness. We argue that molecularity, and hence conservativeness, are implicit presuppositions of speakers’ use of language: the addition of new vocabulary to a language is presupposed to be conservative. But this presupposition is one that we should be able reflectively to endorse (such as when attempting a rational reconstruction of the use of the vocabulary). Thus, where conservativeness is found to fail, this defect should be remedied and the use of the vocabulary corrected (as in classical negation) or excised altogether (as in pejoratives). We go on to characterise a notion of topic neutrality, which we argue applies to logical vocabulary. We then note that reflective endorsement of the conservativeness of a topic neutral vocabulary requires a proof that the vocabulary is conservative relative to any base vocabulary. Thus we require that logical vocabulary be demonstrably conservative. Allying this requirement, distinctive of logic, to a general consideration about the commitments of assertion yields a mode of justification for logical constants akin to some conceptions of Harmony, i.e., to the idea that the consequences of assertion of a logical complex need to be warranted by the grounds and ought to be the strongest consequences warranted by the grounds. Intuitionistic logic acquires a somewhat familiar justification but emanating from a new motivation. (shrink)

In her recent book, Russell (2023) examines various so-called “barriers to entailment,” including Hume’s law, roughly the thesis that an ‘ought’ cannot be derived from an ‘is.’ Hume’s law bears an obvious resemblance to the proscription on fallacies of modality in relevance logic, which has traditionally formally been captured by the so-called Ackermann property. In the context of relevant modal logic, this property might be articulated thus: no conditional whose antecedent is box-free and whose consequent is box-prefixed is valid (for (...) the connection, interpret box deontically). While the deontic significance of Ackermann-like properties has been observed before, Russell’s new book suggests a more broad-scoped formal investigation of the relationship between barrier theses of various kinds and corresponding Ackermann-like properties. In this paper, I undertake such an investigation by elaborating a general relevant bimodal logical framework in which several of the barriers Russell examines can be given formal expression. I then consider various Ackermann-like properties corresponding to these barriers and prove that certain systems satisfy them. Finally, I respond to some objections Russell makes against the use of relevance logic to formulate Hume’s law and related barriers. (shrink)

According to recent social interactionist accounts in developmental psychology, a child's learning to talk about the past with others plays a key role in memory development. Most accounts of this kind are centered on the theoretical notion of autobiographical memory and assume that socio-communicative interaction with others is important, in particular, in explaining the emergence of memories that have a particular type of connection to the self. Most of these accounts also construe autobiographical memory as a species of episodic memory, (...) but its episodic character, as such, is not typically seen as falling within the remit of an explanation in social interactionist terms. I explore the idea that socio-communicative interaction centered on talk about the past might also have an important role to play, quite independently of considerations about the involvement of the self in memory, in accounting for the emergence of memories that are episodic in character, i.e., memories that involve the recollection of particular past events. In doing so, I also try to shed light on a distinctive role that talk about the past plays in socio-communicative interaction. (shrink)

In this paper, I investigate in detail one theoretical approach to the symptom of thought insertion. This approach suggests that patients are lead to disown certain thoughts they are subjected to because they lack a sense of active participation in the occurrence of those thoughts. I examine one reading of this claim, according to which the patients’ anomalous experiences arise from a breakdown of cognitive mechanisms tracking the production of occurrent thoughts, before sketching an alternative reading, according to which their (...) experiences have to be explained in terms of a withdrawal, on the part of the patients themselves, from certain forms of active engagement in reasoning. I conclude with a discussion of the relationship between this view and the idea that patients’ reports of thought insertion reflect a situation in which the boundaries between the self and the world have become uncertain.

Among Dunn’s many important contributions to relevance logic was his work on the system RM (R-mingle). Although RM is an interesting system in its own right, it is widely considered to be too strong. In this chapter, I revisit a closely related system, RM0 (sometimes known as ‘constructive mingle’), which includes the mingle axiom while not degenerating in the way that RM itself does. My main interest will be in examining this logic from two related semantical perspectives. First, I give (...) a purely operational bisemilattice semantics for it by adapting previous work of Humberstone. Second, I examine a more conventional algebraic semantics for it and discuss how this relates to the operational semantics. A novel operational semantics for J (intuitionistic logic) as well as its conventional Heyting algebraic semantics emerge as special cases of the corresponding semantics for RM0. The results of this chapter suggest that RM0 is a more interesting logic than has been appreciated and that Humberstone’s operational semantic framework similarly deserves more attention than it has received.

In this essay I argue that the film Eternal Sunshine of the Spotless Mind eloquently and powerfully suggests a controversial philosophical position: that the harm caused by voluntary memory removal cannot be entirely understood in terms of harms that are consciously experienced. I explore this possibility through a discussion of the film that includes consideration of Nagel and Nozick on unexperienced harms, Kant on duties to oneself, and Murdoch on the requirements of morality.

I present a reconstruction of the logical system of the Tractatus, which differs from classical logic in two ways. It includes an account of Wittgenstein’s “form-series” device, which suffices to express some effectively generated countably infinite disjunctions. And its attendant notion of structure is relativized to the fixed underlying universe of what is named. -/- There follow three results. First, the class of concepts definable in the system is closed under finitary induction. Second, if the universe of objects is countably (...) infinite, then the property of being a tautology is \Pi^1_1-complete. But third, it is only granted the assumption of countability that the class of tautologies is \Sigma_1-definable in set theory. -/- Wittgenstein famously urges that logical relationships must show themselves in the structure of signs. He also urges that the size of the universe cannot be prejudged. The results of this paper indicate that there is no single way in which logical relationships could be held to make themselves manifest in signs, which does not prejudge the number of objects.

Fine (2007) argues that Frege’s puzzle and its relatives demonstrate a need for a basic reorientation of the field of semantics. According to this reorientation, the domain of semantic facts would be closed not under the classical consequence relation but only under a stronger relation Fine calls “manifest consequence.” I examine Fine’s informally sketched analyses of manifest consequence, showing that each can be amended to determine a class of strong consequence relations. A best candidate relation emerges from each of the (...) two classes, and I prove that the two candidates extensionally coincide. The resulting consequence relation is of independent interest, for it might be held to constitute a cogent standard of reasoning that proceeds under a deficient grasp on the identity of objects.

This piece lays out the framework for a special issue on the topic of "Fits and Misfits," published as volume 7, issue 1 of Puncta: A Journal of Critical Phenomenology. We discuss the relationship between the concept of misfitting, coined by Rosemarie Garland-Thomson, and debility, coined by Jasbir Puar, in relationship to scholarship on Merleau-Ponty. We then introduce each of the eight articles in the special issue: Rosemarie Garland-Thomson's "What Misfitting Makes," Susan Bredlau's "Conversational Accessibility: Healthcare, Community, and the Ethics (...) of Everyday Encounters," Helen A. Fielding's "Being Touched by Wellness: Merleau-Ponty, Nancy, and the Intensive Care Unit," Ann Murphy's "The Spirited Interworld: Caregiving and the Liminal Phenomenology of Dementia," Rachel Elliott's "Sharing Time with Misfits: We-Experience across Bodily Difference," David Morris's "An-Archic Time: Melting the Clock as Hypernorm of the I Can -- and Philosophy," Rebecca Longtin's "Merleau-Ponty's Cézanne as Misfit Artist," and, finally, Laura McMahon's "The Politics of Vulnerability and the School for Peace: Insights from Butler, Merleau-Ponty, and Family Systems Theory.".

The use of brain scanning now dominates the cognitive sciences, but important questions remain to be answered about what, exactly, scanning can tell us. One corner of cognitive science that has been transformed by the use of neuroimaging, and that a scanning enthusiast might point to as proof of scanning's importance, is the study of face perception. Against this view, we argue that the use of scanning has, in fact, told us rather little about the information processing underlying face perception (...) and that it is not likely to tell us much more.

Value capture occurs when an agent’s values are rich and subtle; they enter a social environment that presents simplified — typically quantified — versions of those values; and those simplified articulations come to dominate their practical reasoning. Examples include becoming motivated by FitBit’s step counts, Twitter Likes and Re-tweets, citation rates, ranked lists of best schools, and Grade Point Averages. We are vulnerable to value capture because of the competitive advantage that such crisp and clear expressions of value have in (...) our private reasoning and our public justification. There is, however, a price. In value capture, we take a central component of our autonomy — our ongoing deliberation over the exact articulation of our values — and we outsource it. And the metrics to which we outsource usually engineered for the interests of some external force, like a large-scale institution’s interest in cross-contextual comprehensibility and quick aggregability. That outsourcing cuts off one of the key benefits to personal deliberation. In value capture, we no longer adjust our values and their articulations in light of own rich experience of the world. Our values should often be carefully tailored to our particular selves or our small-scale communities, but in value capture, we buy our values off the rack. In some cases – like decreasing CO2 emissions – the costs of non-tailored values are outweighed by the benefit of precise collective coordination. In other cases, like in our aesthetic lives, they are not. This suggests that we should want different values suited to different scales. We should want value federalism. Some values are perhaps best pursued at the largest-scale level, others at smaller scales. The problem occurs when we exhibit an excess preference for the largest-scale values – when we consistently let the universal metrics swamp our quieter interests. (shrink)

Naturalist views of persons, such as those of the philosophers Annette Baier and Marjorie Grene, emphasize that human persons are cultural animals: We are living, embodied, organic beings, embedded in nature, the product of Darwinian evolution, but dependent on culture. Such naturalist views of persons typically eschew science fiction and look askance at the philosophical fantasies and thought experiments that often populate philosophical treatments of personal identity. Marge Piercy’s dystopian, cyberpunk, science fiction novel He, She and It weaves a complex (...) tale around the debate over the status of its central character Yod, a cyborg created in a lab but humanized through the efforts of two women, Malkah Shipman and her granddaughter Shira Shipman. Is Yod a person, despite having been engineered in a lab for a specific purpose? Piercy’s tale both challenges and ultimately supports a naturalist view of persons while simultaneously forewarning us of possible new styles of persons to come. (shrink)

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with reasons (...) for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

This article provides an introduction to a special issue of the journal Philosophy, Psychiatry and Psychology, On Understanding and Explaining Schizophrenia. The article identifies a common thread running through the different contributions to this special issue, inspired by Jaspers's (1963) suggestion that a profound impairment in the ability to engage in interpersonal and social relations is a key factor in psychiatric disorders. It is argued that this suggestion can help solve a central dilemma in psychopathology, which is to make intelligible (...) the emergence and nature of psychiatric phenomena involving disturbances of rationality, intentionality and self-consciousness, whilst at the same time accounting for a sense in which such phenomena resist understanding.

The paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: an epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and to (...) the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories. (shrink)

A central tension shaping metaethical inquiry is that normativity appears to be subjective yet real, where it’s difficult to reconcile these aspects. On the one hand, normativity pertains to our actions and attitudes. On the other, normativity appears to be real in a way that precludes it from being a mere figment of those actions and attitudes. In this paper, I argue that normativity is indeed both subjective and real. I do so by way of treating it as a special (...) sort of artifact, where artifacts are mind-dependent yet nevertheless can carve at the joints of reality. In particular, I argue that the properties of being a reason and being valuable for are grounded in attitudes yet are still absolutely structural. (shrink)

What does Wittgenstein say about the learning child? In the Philosophical Investigations, he writes, ‘An important part … will consist in the teacher’s pointing to the objects, directing the child’s attention to them, and at the same time uttering a word.’ Here Wittgenstein is describing what is called ‘joint attention’ which is agreed to be a rich resource for learning in children. In this essay, I explore the developmental significance of this passage particularly with regards the learning that occurs in (...) the pre-linguistic child during joint attention. I refer to critical remarks elsewhere in the PI which can help further convey what Wittgenstein means when he talks about attentional capacities and how they develop, including the relevant ability for responsiveness required for the learning to proceed. These considerations should motivate a defence of the social initiation model of learning contra Luntley’s mentalist-individualist account, this despite conceding that certain prior capacities do play a role, though not a central one since these do not pick out the relevant ability (responsiveness) required for learning to take place in the child.

Decety presents evidence for the claim that neural mechanisms involved in the generation of actions are also recruited in the observation and mental simulation of actions. This paper explores the relationship between such neuropsychological findings and our common-sense understanding of what it is for a person to imitate or imagine performing an action they have observed. A central question is whether imitation and imagination necessarily involve the ability to distinguish between one's own actions and those of others. It is argued (...) that certain imitative and imaginative capacities can be present, and play a key role in the acquisition of knowledge, even in the absence of an ability to distinguish between self and other in this way.

Political epistemology is the intersection of political philosophy and epistemology. This paper develops a political 'hinge' epistemology. Political hinge epistemology draws on the idea that all belief systems have fundamental presuppositions which play a role in the determination of reasons for belief and other attitudes. It uses this core idea to understand and tackle political epistemological challenges, like political disagreement, polarization, political testimony, political belief, ideology, and biases, among other possibilities. I respond to two challenges facing the development of a (...) political hinge epistemology. The first is about nature and demarcation of political hinges, while the second is about rational deliberation over political hinges. I then use political hinge epistemology to analyze ideology, dealing with the challenge of how an agent's ideology 'masks' or distorts their understanding of social reality, along with the challenge of how ideology critique can change the beliefs of agents who adhere to dominant ideologies, if agents only have their own or the competing ideology to rely on (see Haslanger 2017). I then explore how political hinge epistemology might be extended to further our understanding of political belief polarization. (shrink)

Should economics study the psychological basis of agents' choice behaviour? I show how this question is multifaceted and profoundly ambiguous. There is no sharp distinction between "mentalist'' answers to this question and rival "behavioural'' answers. What's more, clarifying this point raises problems for mentalists of the "functionalist'' variety (Dietrich and List, 2016). Firstly, functionalist hypotheses collapse into hypotheses about input--output dispositions, I show, unless one places some unwelcome restrictions on what counts as a cognitive variable. Secondly, functionalist hypotheses make some (...) risky commitments about the plasticity of agents' choice dispositions. (shrink)

This paper examines the debate between permissive and impermissive forms of Bayesianism. It briefly discusses some considerations that might be offered by both sides of the debate, and then replies to some new arguments in favor of impermissivism offered by Roger White. First, it argues that White’s (Oxford studies in epistemology, vol 3. Oxford University Press, Oxford, pp 161–186, 2010) defense of Indifference Principles is unsuccessful. Second, it contends that White’s (Philos Perspect 19:445–459, 2005) arguments against permissive views do not (...) succeed. (shrink)

Propositional contingentism is the view that what propositions there are is a contingent matter—certain propositions ontologically depend on objects which themselves only contingently exist. Possible worlds are, loosely, complete ways the world could have been. That is to say, the ways in which everything in its totality could have been. Propositional contingentists make use of possible worlds frequently. However, a neglected, but important, question concerns whether there are any notions of worlds which are both theoretically adequate and consistent with propositional (...) contingentism. Some notion of a possible world is adequate if the systematic connection between, at least, possibility and truth at some possible world holds. Here, I argue that no adequate notion of a possible world is available to at least those who subscribe to one natural formulation of propositional contingentism. I also show that this result contrasts with a simple and adequate definition of a possible world available to the necessitist—those who hold that necessarily everything necessarily exists. (shrink)

Serious actualism is the view that it is metaphysically impossible for an entity to have a property, or stand in a relation, and not exist. Fine (1985) and Pollock (1985) influentially argue that this view is false. In short, there are properties like the property of nonexistence, and it is metaphysically possible that some entity both exemplifies such a property and does not exist. I argue that such arguments are indeed successful against the standard formulation of serious actualism. However, I (...) also argue that we should distinguish a weaker formulation of serious actualism using the actualist distinction between truth in, and truth at, a possible world. This weaker formulation is then shown to be consistent with the existence and possible exemplification of properties like the property of nonexistence. I end with a novel argument for the truth of the weaker formulation. (shrink)

Much of the philosophical literature on causation has focused on the concept of actual causation, sometimes called token causation. In particular, it is this notion of actual causation that many philosophical theories of causation have attempted to capture.2 In this paper, we address the question: what purpose does this concept serve? As we shall see in the next section, one does not need this concept for purposes of prediction or rational deliberation. What then could the purpose be? We will argue (...) that one can gain an important clue here by looking at the ways in which causal judgments are shaped by people‘s understanding of norms. (shrink)

Philosophers of science and medicine now aspire to provide useful, socially relevant accounts of mechanism. Existing accounts have forged the path by attending to mechanisms in historical context, scientific practice, the special sciences, and policy. Yet, their primary focus has been on more proximate issues related to therapeutic effectiveness. To take the next step toward social relevance, we must investigate the challenges facing researchers, clinicians, and policy makers involving values and social context. Accordingly, we learn valuable lessons about the connections (...) between mechanistic processes and more fundamental reasons for medical interventions, particularly moral, ethical, religious, and political concerns about health, agency, and power. This paper uses debates over the controversial morning-after pill to gain insight into the deeper reasons for the production and use of mechanistic knowledge throughout biomedical research, clinical practice, and governmental regulation. To practice socially relevant philosophy of science, I argue that we need to account for mechanistic knowledge beyond immediate effectiveness, such as how it can also provide moral guidance, aid ethical categorization in the clinic, and function as a political instrument. Such insights have implications for medical epistemology, including the value-laden dimensions of mechanistic reasoning and the “epistemic friction” of values. Furthermore, there are broader impacts for teaching research ethics and understanding the role of science advisors as political advocates. (shrink)

Brauer (2022) has recently argued that if it is possible that there is nothing, then the correct modal logic for metaphysical modality cannot include D. Here, I argue that Brauer’s argument is unsuccessful; or at the very least significantly weaker than presented. First, I outline a simple argument for why it is not possible that there is nothing. I note that this argument has a well-known solution involving the distinction between truth in and truth at a possible world. However, I (...) then argue that once the semantics presupposed by Brauer’s argument is reformulated in terms of truth at a world, we have good reasons to think that a crucial semantic premise in Brauer’s argument should be rejected in favour of an alternative. Brauer’s argument is, however, no longer valid with this alternative premise. Thus, plausibly Brauer’s argument against D is only valid, if it is not sound. (shrink)

Ecological communities are seldom, if ever, biological individuals. They lack causal boundaries as the populations that constitute communities are not congruent and rarely have persistent functional roles regulating the communities’ higher-level properties. Instead we should represent ecological communities indexically, by identifying ecological communities via the network of weak causal interactions between populations that unfurl from a starting set of populations. This precisification of ecological communities helps identify how community properties remain invariant, and why they have robust characteristics. This respects the (...) diversity and aggregational nature of these complex systems while still vindicating them as units worthy of investigation. (shrink)

Interactions between an intelligent software agent and a human user are ubiquitous in everyday situations such as access to information, entertainment, and purchases. In such interactions, the ISA mediates the user’s access to the content, or controls some other aspect of the user experience, and is not designed to be neutral about outcomes of user choices. Like human users, ISAs are driven by goals, make autonomous decisions, and can learn from experience. Using ideas from bounded rationality, we frame these interactions (...) as instances of an ISA whose reward depends on actions performed by the user. Such agents benefit by steering the user’s behaviour towards outcomes that maximise the ISA’s utility, which may or may not be aligned with that of the user. Video games, news recommendation aggregation engines, and fitness trackers can all be instances of this general case. Our analysis facilitates distinguishing various subcases of interaction, as well as second-order effects that might include the possibility for adaptive interfaces to induce behavioural addiction, and/or change in user belief. We present these types of interaction within a conceptual framework, and review current examples of persuasive technologies and the issues that arise from their use. We argue that the nature of the feedback commonly used by learning agents to update their models and subsequent decisions could steer the behaviour of human users away from what benefits them, and in a direction that can undermine autonomy and cause further disparity between actions and goals as exemplified by addictive and compulsive behaviour. We discuss some of the ethical, social and legal implications of this technology and argue that it can sometimes exploit and reinforce weaknesses in human beings. (shrink)

This handbook article gives a critical overview of recent discussions of epistemic authority. It favors an account that brings into balance the dictates of rational deference with the ideals of intellectual self-governance. A plausible starting point is the conjecture that neither should rational deference to authorities collapse into total epistemic submission, nor the ideal of mature intellectual self-governance be conflated with (illusions of) epistemic autarky.

Let serious propositional contingentism (SPC) be the package of views which consists in (i) the thesis that propositions expressed by sentences featuring terms depend, for their existence, on the existence of the referents of those terms, (ii) serious actualism—the view that it is impossible for an object to exemplify a property and not exist—and (iii) contingentism—the view that it is at least possible that some thing might not have been something. SPC is popular and compelling. But what should we say (...) about possible worlds, if we accept SPC? Here, I first show that a natural view of possible worlds, well-represented in the literature, in conjunction with SPC is inadequate. Though I note various alternative ways of thinking about possible worlds in response to the first problem, I then outline a second more general problem—a master argument—which generally shows that any account of possible worlds meeting very minimal requirements will be inconsistent with compelling claims about _mere possibilia_ which the serious propositional contingentist should accept.

An adequate account of laws should satisfy at least five desiderata: it should provide a unified account of laws and chances, it should yield plausible relations between laws and chances, it should vindicate numerical chance assignments, it should accommodate dynamical and non-dynamical chances, and it should accommodate a plausible range of nomic possibilities. No extant account of laws satisfies these desiderata. This paper presents a non-Humean account of laws, the Nomic Likelihood Account, that does.

This chapter (Chapter 7) presents a reconstruction of purely doxastic states in Kant’s theory of assent, focusing on those species of assents that are distinguished solely by the strength of their psychological commitment. It is suggested that Kant held a view, according to which (i) our degreed doxastic states can be articulated as degrees of conviction, and (ii) our outright doxastic states — above all, opinion, conviction (simpliciter), and certainty — can be reduced to conviction thresholds. Moreover, it is suggested (...) that Kant’s notion of ‘assent’ (‘Fürwahrhalten’), as the most general doxastic state, comes closest to our present-day notion of ‘belief’.

This article presents the first thematic review of the literature on the ethical issues concerning digital well-being. The term ‘digital well-being’ is used to refer to the impact of digital technologies on what it means to live a life that isgood fora human being. The review explores the existing literature on the ethics of digital well-being, with the goal of mapping the current debate and identifying open questions for future research. The review identifies major issues related to several key social (...) domains: healthcare, education, governance and social development, and media and entertainment. It also highlights three broader themes: positive computing, personalised human–computer interaction, and autonomy and self-determination. The review argues that three themes will be central to ongoing discussions and research by showing how they can be used to identify open questions related to the ethics of digital well-being.

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)

We explore the question of whether machines can infer information about our psychological traits or mental states by observing samples of our behaviour gathered from our online activities. Ongoing technical advances across a range of research communities indicate that machines are now able to access this information, but the extent to which this is possible and the consequent implications have not been well explored. We begin by highlighting the urgency of asking this question, and then explore its conceptual underpinnings, in (...) order to help emphasise the relevant issues. To answer the question, we review a large number of empirical studies, in which samples of behaviour are used to automatically infer a range of psychological constructs, including affect and emotions, aptitudes and skills, attitudes and orientations (e.g. values and sexual orientation), personality, and disorders and conditions (e.g. depression and addiction). We also present a general perspective that can bring these disparate studies together and allow us to think clearly about their philosophical and ethical implications, such as issues related to consent, privacy, and the use of persuasive technologies for controlling human behaviour.

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine.

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived (...) of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge.

What is philosophy of science? Numerous manuals, anthologies or essays provide carefully reconstructed vantage points on the discipline that have been gained through expert and piecemeal historical analyses. In this paper, we address the question from a complementary perspective: we target the content of one major journal of the field—Philosophy of Science—and apply unsupervised text-mining methods to its complete corpus, from its start in 1934 until 2015. By running topic-modeling algorithms over the full-text corpus, we identified 126 key research topics (...) that span across 82 years. We also tracked their evolution and fluctuating significance over time in the journal articles. Our results concur with and document known and lesser-known episodes of the philosophy of science, including the rise and fall of logic and language-related topics, the relative stability of a metaphysical and ontological questioning (space and time, causation, natural kinds, realism), the significance of epistemological issues about the nature of scientific knowledge as well as the rise of a recent philosophy of biology and other trends. These analyses exemplify how computational text-mining methods can be used to provide an empirical large-scale and data-driven perspective on the history of philosophy of science that is complementary to other current historical approaches.

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

In this essay, I argue that a proper understanding of the historicity of love requires an appreciation of the irreplaceability of the beloved. I do this through a consideration of ideas that were first put forward by Robert Kraut in “Love De Re” (1986). I also evaluate Amelie Rorty's criticisms of Kraut's thesis in “The Historicity of Psychological Attitudes: Love is Not Love Which Alters Not When It Alteration Finds” (1986). I argue that Rorty fundamentally misunderstands Kraut's Kripkean analogy, and (...) I go on to criticize her claim that concern over the proper object of love should be best understood as a concern over constancy. This leads me to an elaboration of the distinct senses in which love can be seen as historical. I end with a further defense of the irreplaceability of the beloved and a discussion of the relevance of recent debates over the importance of personal identity for an adequate account of the historical dimension of love.

In ‘A reductio of coherentism’ (Analysis 67, 2007) Tom Stoneham offers a novel argument against epistemological coherentism. ‘On the face of it’, he writes, ‘the argument gives a conclusive reductio ad absurdum of any coherence theory of justification. But that cannot be right, can it?’ (p. 254). It could be right, but it isn’t. I argue that coherentists need not accept the central premises of Stoneham’s argument and that, even if these premises were acceptable and true, Stoneham’s reductio would not (...) follow. (shrink)

The question of the holistic structure of an organism is a recurring theme in the philosophy of biology and has been increasingly discussed again in recent years. Organisms have recently been described as complex systems that autonomously create, maintain and reproduce themselves while constantly interacting with their environment. Key focal points include their autopoiesis, autonomy, agency and teleological structure. This perspective marks a significant advancement from the 20th-century viewpoint, which predominantly saw organisms as genetically programmed, randomly generated and blindly selected (...) survival-machines. However, crucial questions about the shape and development of organisms still lack answers. Shape and development are deeply interconnected and seem to require a holistic approach. Here, I will briefly outline a phenomenological perspective which could provide a framework for seeking answers to these fundamental questions. In particular, I propose a common four-fold phenomenal structure of the developing organism and the cognising consciousness, which makes it possible to observe the agential and teleological structure of the organism "from within". This fourfold structure also describes the molecular level and thus provides a general organismic concept. It furthermore corresponds to the four Aristotelian "causes" (conditions). (shrink)

The article develops a general theory of the goals of free moral commitment. The theoretical hook is the discussion of the strict efficiency striving as demanded by the movement and theory of effective altruism. A detailed example shows prima facie counterintuitive consequences of this efficiency striving, the analysis of which reveals various problems such as: merely point-like but not structural commitment; radical universalism; violation of established moral standards and institutions. The article takes these problems as an occasion to develop a (...) general theory of moral investment with moral guidelines and planning instruments of its implementation such as: efficiency; preservation of existing moral standards and obligations, especially also towards those close to one; rooted universalism with adequate consideration of all beneficiaries of one's moral concern through allocation of separate budgets; real efficiency also through inclusion of strategic and organic investments.

Does our life have value for us after we die? Despite the importance of such a question, many would find it absurd, even incoherent. Once we are dead, the thought goes, we are no longer around to have any wellbeing at all. However, in this paper I argue that this common thought is mistaken. In order to make sense of some of our most central normative thoughts and practices, we must hold that a person can have wellbeing after they die. (...) I provide two arguments for this claim on the basis of postmortem harms and benefits as well as the lasting significance of death. I suggest two ways of underwriting posthumous wellbeing. (shrink)

In Modal Logic as Metaphysics, Timothy Williamson claims that the possibilism-actualism (P-A) distinction is badly muddled. In its place, he introduces a necessitism-contingentism (N-C) distinction that he claims is free of the confusions that purportedly plague the P-A distinction. In this paper I argue first that the P-A distinction, properly understood, is historically well-grounded and entirely coherent. I then look at the two arguments Williamson levels at the P-A distinction and find them wanting and show, moreover, that, when the N-C (...) distinction is broadened (as per Williamson himself) so as to enable necessitists to fend off contingentist objections, the P-A distinction can be faithfully reconstructed in terms of the N-C distinction. However, Williamson’s critique does point to a genuine shortcoming in the common formulation of the P-A distinction. I propose a new definition of the distinction in terms of essential properties that avoids this shortcoming. (shrink)
