This paper adds to the philosophical literature on mechanistic explanation by elaborating two related explanatory functions of idealisation in mechanistic models. The first function involves explaining the presence of structural/organizational features of mechanisms by reference to their role as difference-makers for performance requirements. The second involves tracking counterfactual dependency relations between features of mechanisms and features of mechanistic explanandum phenomena. To make these functions salient, we relate our discussion to an exemplar from systems biological research on the mechanism for countering (...) heat shock—the heat shock response system—in Escherichia coli bacteria. This research also reinforces a more general lesson: ontic constraint accounts in the literature on mechanistic explanation provide insufficiently informative normative appraisals of mechanistic models. We close by outlining an alternative view on the explanatory norms governing mechanistic representation. (shrink)

What features will something have if it counts as an explanation? And will something count as an explanation if it has those features? In the second half of the 20th century, philosophers of science set for themselves the task of answering such questions, just as a priori conceptual analysis was generally falling out of favor. And as it did, most philosophers of science just moved on to more manageable questions about the varieties of explanation and discipline-specific scientific explanation. Often, such (...) shifts are sound strategies for problem-solving. But leaving fallow certain basic conceptual issues can also result in foundational debates. (shrink)

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.

This paper examines three accounts of the sleeping beauty case: an account proposed by Adam Elga, an account proposed by David Lewis, and a third account defended in this paper. It provides two reasons for preferring the third account. First, this account does a good job of capturing the temporal continuity of our beliefs, while the accounts favored by Elga and Lewis do not. Second, Elga’s and Lewis’ treatments of the sleeping beauty case lead to highly counterintuitive consequences. The proposed (...) account also leads to counterintuitive consequences, but they’re not as bad as those of Elga’s account, and no worse than those of Lewis’ account. (shrink)

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.

Kevin Elliott and others separate two common arguments for the legitimacy of societal values in scientific reasoning as the gap and the error arguments. This article poses two questions: How are these two arguments related, and what can we learn from their interrelation? I contend that we can better understand the error argument as nested within the gap because the error is a limited case of the gap with narrower features. Furthermore, this nestedness provides philosophers with conceptual tools for analyzing (...) more robustly how values pervade science. (shrink)

Activist artists often face a difficult question: is striving to change the world undermined when pursued through difficult and experimental artistic means? Looking closely at Adrian Piper's 'Four Intruders plus Alarm Systems' (1980), I will consider why this is an important concern for activist art, and assess three different responses in relation to Piper’s work. What I call the conciliatory stance recommends that when activist artists encounter misunderstanding, they should downplay their experimental artistry in favor of fitting their work to (...) their audience's appreciative capacities. What I call the steadfast stance recommends that activist artists have reason to use their privilege of artistic exceptionalism to challenge their audience's expectations, even if this leads to misunderstanding. I claim that a middle position that I call liberal conciliation best balances the demands for actual change placed on activism and the experimental means that artists bring to activism. (shrink)

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.

This thesis is about Kant’s account of reason. In the Critique of Pure Reason, Kant introduces reason as an infinitely demanding faculty that seeks complete explanations for all observable phenomena. This account of reason is essential to Kant’s discussion in the Transcendental Dialectic and prompts the primary question of this thesis: how does Kant justify such an infinitely demanding faculty? How does he think we come to know that we have reason, so understood? Traditionally, Kant scholars have held that we (...) can grasp our mental faculties either through a priori awareness of their unique activities or through transcendental arguments. Both approaches, however, fail with reason, which presents unique metacritical challenges. We can never be aware of reason’s unique activities, which are infinite and so never complete, and reason cannot be established via transcendental argument because it is not necessary for the possibility of experience. So, how can we know that we have reason? This thesis breaks with tradition by arguing that reason gains self-knowledge in empirical psychology, the study of phenomena in inner sense. Reason, according to Kant, seeks to explain all phenomena, including those of inner sense. To explain inner phenomena, reason hypothesises mental faculties and their laws. Our ten- dency to ask why-questions, Kant argues, is best explained by hypothesising a faculty that demands complete explanations – i.e., reason. The thesis has five chapters. The first shows that, for Kant, mental facul- ties are (also) powers of inner sense. The second argues that the normative demands of these faculties are grounded in constitutive principles or laws. The third finds that the constitutive principle of reason requires us to sys- tematise powers of nature, which, as the fourth chapter explains, we do by hypothesising their respective laws. Finally, the fifth chapter suggests that reason hypothesises its own explanation-seeking law. (shrink)

This is a comprehensive book on the philosophy of time. Leading philosophers discuss the metaphysics of time, our experience and representation of time, the role of time in ethics and action, and philosophical issues in the sciences of time, especially quantum mechanics and relativity theory.

This paper challenges the prevailing notion in vulnerability theory that only relational vulnerability holds moral significance for aiding the vulnerable. Contrary to this stance, I contend that ontological vulnerability carries moral relevance, and thus grounds a consequentialist duty to mitigate potential harm. This duty constitutes the core ethical principle of transhumanism. My aim will therefore be to defend transhumanism’s central moral tenet from within the framework of vulnerability theory, by showing that ontological vulnerability has moral significance. Section 1 will introduce (...) transhumanism’s moral objective, emphasizing the role of ontological vulnerability. Section 2 will analyze the relational and dispositional accounts of vulnerability, emphasizing the reasons why such kinds of vulnerabilities ground duties to help the vulnerable. Section 3 argues that these same reasons also ground moral obligations to remedy ontological vulnerability, therefore committing us to endorse transhumanism’s moral endeavor highlighted in section 1.

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)

How does good combine with bad? Most creatures are neither so blessed as to only enjoy good nor so cursed as to only suffer bad. Rather, the good and bad they receive throughout their lives combine to produce their overall quality of life. But it’s not just whole lives that have combined good and bad. Many stretches within contain both positive and negative occurrences whose value is joined to form the overall quality of that span of time. In a single (...) morning someone might wake up, brush their teeth, stub their toe groggily lumbering down the stairs, and have a sip of coffee that’s tasty but so hot they burn their tongue. These events are good and bad for them to various degrees, and their value comes together to form an overall value for them of that morning. A single moment, even, can have combined value from distinct pockets of good and bad that occur simultaneously. The tastiness of the coffee is good, but the pain of the heat is bad. They combine to form an overall value of the sipping moment – negative if the pain outweighed the flavor. Thus, wellbeing and illbeing combine. But how? How can someone rightly chastise themselves for sipping the overly hot coffee when it was, in fact, good because it was tasty? To pose the question starkly, a life can be bad, even so bad to not be worth living, and yet it can have many instances of good, where these goods are, in themselves, pure of any negativity. But how can good make something bad? (shrink)

I argue that the theory of chance proposed by David Lewis has three problems: (i) it is time asymmetric in a manner incompatible with some of the chance theories of physics, (ii) it is incompatible with statistical mechanical chances, and (iii) the content of Lewis's Principal Principle depends on how admissibility is cashed out, but there is no agreement as to what admissible evidence should be. I proposes two modifications of Lewis's theory which resolve these difficulties. I conclude by tentatively (...) proposing a third modification of Lewis's theory, one which explains many of the common features shared by the chance theories of physics. (shrink)

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.

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)

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.

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)

In times of populist mistrust towards experts, it is important and the aim of the paper to ascertain the rationality of arguments from expert opinion and to reconstruct their rational foundations as well as to determine their limits. The foundational approach chosen is probabilistic. However, there are at least three correct probabilistic reconstructions of such argumentations: statistical inferences, Bayesian updating, and interpretive arguments. To solve this competition problem, the paper proposes a recourse to the arguments' justification strengths achievable in the (...) respective situation. (shrink)

We discuss the social-epistemic aspects of Catherine Elgin’s theory of reflective equilibrium and understanding and argue that it yields an argument for the view that a crucial social-epistemic function of epistemic authorities is to foster understanding in their communities. We explore the competences that enable epistemic authorities to fulfil this role and argue that among them is an epistemic virtue we call “epistemic empathy”.

We identify a particular type of causal reasoning ability that we believe is required for the possession of episodic memories, as it is needed to give substance to the distinction between the past and the present. We also argue that the same causal reasoning ability is required for grasping the point that another person's appeal to particular past events can have in conversation. We connect this to claims in developmental psychology that participation in joint reminiscing plays a key role in (...) memory development. (shrink)

Conditionalization is a widely endorsed rule for updating one’s beliefs. But a sea of complaints have been raised about it, including worries regarding how the rule handles error correction, changing desiderata of theory choice, evidence loss, self-locating beliefs, learning about new theories, and confirmation. In light of such worries, a number of authors have suggested replacing Conditionalization with a different rule — one that appeals to what I’ll call “ur-priors”. But different authors have understood the rule in different ways, and (...) these different understandings solve different problems. In this paper, I aim to map out the terrain regarding these issues. I survey the different problems that might motivate the adoption of such a rule, flesh out the different understandings of the rule that have been proposed, and assess their pros and cons. I conclude by suggesting that one particular batch of proposals, proposals that appeal to what I’ll call “loaded evidential standards”, are especially promising. (shrink)

This paper defends the claim that, in order to have a concept of time, subjects must have memories of particular events they once witnessed. Some patients with severe amnesia arguably still have a concept of time. Two possible explanations of their grasp of this concept are discussed. They take as their respective starting points abilities preserved in the patients in question: (1) the ability to retain factual information over time despite being unable to recall the past event or situation that (...) information stems from, and (2) the ability to remember at least some past events or situations themselves (typically because retrograde amnesia is not complete). It is argued that a satisfactory explanation of what it is for subjects to have a concept of time must make reference to their having episodic memories such as those mentioned under (2). It is also shown how the question as to whether subjects have such memories, and thus whether they possess a concept of time, enters into our explanation of their actions. (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)

Many questions about wellbeing involve metaphysical dependence. Does wellbeing depend on minds? Is wellbeing determined by distinct sorts of things? Is it determined differently for different subjects? However, we should distinguish two axes of dependence. First, there are the grounds that generate value. Second, there are the connections between the grounds and value which make it so that those grounds generate that value. Given these distinct axes of dependence, there are distinct dimensions to questions about the dependence of wellbeing. In (...) this paper, I offer a view of wellbeing that gives different answers with respect to these different dimensions. The view is subjectivist about connections but objectivist about grounds. Pluralist about grounds but monist about connections. Invariabilist about connections but variabilist about grounds. Thus, the view offers a simple account that captures the complexity of wellbeing.

Ectogestation involves the gestation of a fetus in an ex utero environment. The possibility of this technology raises a significant question for the abortion debate: Does a woman’s right to end her pregnancy entail that she has a right to the death of the fetus when ectogestation is possible? Some have argued that it does not Mathison & Davis. Others claim that, while a woman alone does not possess an individual right to the death of the fetus, the genetic parents (...) have a collective right to its death Räsänen. In this paper, I argue that the possibility of ectogestation will radically transform the problem of abortion. The argument that I defend purports to show that, even if it is not a person, there is no right to the death of a fetus that could be safely removed from a human womb and gestated in an artificial womb, because there are competent people who are willing to care for and raise the fetus as it grows into a person. Thus, given the possibility of ectogestation, the moral status of the fetus plays no substantial role in determining whether there is a right to its death. (shrink)

This paper aims to investigate the temporal content of perceptual experience. It argues that we must recognize the existence of temporal perceptions, i.e., perceptions the content of which cannot be spelled out simply by looking at what is the case at an isolated instant. Acts of apprehension can cover a succession of events. However, a subject who has such perceptions can fall short of having a concept of time. Similar arguments have been put forward to show that a subject who (...) has spatial perceptions can fall short of having a concept of space. In both cases, it is the fact that perception is from a point of view which stands in the way of it constituting an exercise of a concept of how things are objectively. However, the paper also shows that the way in which perception is perspectival takes a different form in each of the two cases. (shrink)

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.

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)

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.

Philosophical discussions concerning ectogestation are trending. And given that the Supreme Court of the United States overturned Roe v. Wade (1973) and Casey v. Planned Parenthood (1992), questions regarding the moral and legal status of abortion in light of the advent of ectogestation will likely continue to be of central importance in the coming years. If ectogestation can intersect with or even determine abortion policy in the future, then a new philosophical analysis of the legal status of abortion is both (...) warranted and urgently needed. I argue that, even if there is no ‘moral’ right to fetal destruction once ectogestation becomes a reality, societies ought not to implement legal prohibitions on a pregnant person’s ability to safely obtain an abortion that results in fetal death because such laws are systemically misogynistic.

As there is currently a neo-Aristotelian revival currently taking place within contemporary metaphysics and dispositions, or causal powers are now being routinely utilised in theories of causality and modality, more attention is beginning to be paid to a central Aristotelian concern: the metaphysics of substantial unity, and the doctrine of hylomorphism. In this paper, I distinguish two strands of hylomorphism present in the contemporary literature and argue that not only does each engender unique conceptual difficulties, but neither adequately captures the (...) metaphysics of Aristotelian hylomorphism. Thus both strands of contemporary hylomorphism, I argue, fundamentally misunderstand what substantial unity amounts to in the hylomorphic framework – namely, the metaphysical inseparability of matter and form.

Selection against embryos that are predisposed to develop disabilities is one of the less controversial uses of embryo selection technologies. Many bio-conservatives argue that while the use of ESTs to select for non-disease-related traits, such as height and eye-colour, should be banned, their use to avoid disease and disability should be permitted. Nevertheless, there remains significant opposition, particularly from the disability rights movement, to the use of ESTs to select against disability. In this article we examine whether and why the (...) state could be justified in restricting the use of ESTs to select against disability. We first outline the challenge posed by proponents of ‘liberal eugenics’. Liberal eugenicists challenge those who defend restrictions on the use of ESTs to show why the use of these technologies would create a harm of the type and magnitude required to justify coercive measures. We argue that this challenge could be met by adverting to the risk of harms to future persons that would result from a loss of certain forms of cognitive diversity. We suggest that this risk establishes a pro tanto case for restricting selection against some disabilities, including dyslexia and Asperger's syndrome. (shrink)

What does social justice require in contemporary societies? What are the requirements of social democracy? Who and where are the individuals and groups that can carry forward agendas for progressive social transformation? What are we to make of the so-called new social movements of the last thirty years? Is identity politics compatible with egalitarianism? Can cultural misrecognition and economic maldistribution be fought simultaneously? What of the heritage of Western Marxism is alive and dead? And how is current critical social theory (...) to approach these and other questions? Much of the most productive work done in recent social theory has revolved around such issues, in particular, around those concerning the relationship between the politics of recognition and the politics of distribution. After the intense theoretical focus over the last fifteen years or so on the issues of recognition politics—multiculturalism, multi-nationalism, identity politics, group-differentiated rights, the accommodation of difference, and so on—some social theorists have worried that attention has been diverted from important issues of distributive equality—systematic impoverishment, increasing material inequality, ‘structural’ unemployment, the growth of oligarchic power, global economic segmentation, and so on. While some critics seem to have adopted a blunt ‘it’s the economy, stupid’ line of criticism,1 others have attempted to develop an overarching, integrative theoretical framework adequate to the diverse issues concerning both economic and cultural justice. For example, Axel Honneth proposes that a suitably developed and normatively robust theory of intersubjective recognition can adequately integrate an analysis of apparently diverse contemporary struggles: those for a just division of labor and hence, a fair distribution of resources and opportunities, as well as those for a culture free of identity-deforming disrespect and denigration.

Propositional contingentism is the thesis that there might have been propositions which might have not have been something. Serious actualism is the thesis that it is impossible for a property to be exemplified without there being something which exemplifies it. Both are popular. Likewise, the dominant view in the metaphysics of modality is that metaphysical possibility and necessity can be understood – in some sense – in terms of possible worlds, i.e. total ways the world could have been. Here, I (...) argue that, given some minimal assumptions, the conjunction of propositional contingentism and serious actualism entails that worlds are modally fragile – every world is ontologically dependent on every proposition. I then show that such a consequence is inconsistent with the claim that propositions true at all possible worlds are necessary. (shrink)

Standard decision theory has trouble handling cases involving acts without finite expected values. This paper has two aims. First, building on earlier work by Colyvan (2008), Easwaran (2014), and Lauwers and Vallentyne (2016), it develops a proposal for dealing with such cases, Difference Minimizing Theory. Difference Minimizing Theory provides satisfactory verdicts in a broader range of cases than its predecessors. And it vindicates two highly plausible principles of standard decision theory, Stochastic Equivalence and Stochastic Dominance. The second aim is to (...) assess some recent arguments against Stochastic Equivalence and Stochastic Dominance. If successful, these arguments refute Difference Minimizing Theory. This paper contends that these arguments are not successful. (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)

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)

What is the connection between the way we represent time and things in time, on the one hand, and our capacity to remember particular past events, on the other?

This article endorses a familiar, albeit controversial, argument for the existence of group-based reasons for action, but then rejects two doctrines which other advocates of such reasons usually accept. One such doctrine is the willingness requirement, which says that a group-based reason exists only if (sufficient) other members of the group in question are willing to cooperate. Thus the paper argues that there is sometimes a reason, which derives from the rationality of some group action, to play one's part unilaterally (...) in that group action. This seems implausible only because we tend wrongly to accept a second doctrine, monism about the unit of agency. Monism claims that, for any given deliberative problem, there is only one unit of agency to which reasons attach. If we are monists who believe in group-based reasons, the willingness requirement will seem necessary in order to avoid recklessness. We should reject monism, and if we do so we can recognise genuine conflict between individual-based and group-based reasons, and in doing so we can explain, without endorsing the willingness requirement, why we should not act recklessly.

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)

In the quantum-Bayesian approach to quantum foundations, a quantum state is viewed as an expression of an agent’s personalist Bayesian degrees of belief, or probabilities, concerning the results of measurements. These probabilities obey the usual probability rules as required by Dutch-book coherence, but quantum mechanics imposes additional constraints upon them. In this paper, we explore the question of deriving the structure of quantum-state space from a set of assumptions in the spirit of quantum Bayesianism. The starting point is the representation (...) of quantum states induced by a symmetric informationally complete measurement or SIC. In this representation, the Born rule takes the form of a particularly simple modification of the law of total probability. We show how to derive key features of quantum-state space from (i) the requirement that the Born rule arises as a simple modification of the law of total probability and (ii) a limited number of additional assumptions of a strong Bayesian flavor.

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’.

At the centre of Arthur Prior’s ‘Thank goodness’ argument for the A-theory of time is a particular form of relief. Time must objectively pass, Prior argues, or else the relief felt when a painful experience has ended is not intelligible. In this paper, I offer a detailed analysis of the type of relief at issue in this argument, which I call temporal relief, and distinguish it from another form of relief, which I refer to as counterfactual relief. I also argue (...) that existing discussions of the ‘Thank goodness’ argument—including Prior’s own—fail to give a satisfactory account of temporal relief, and that it needs to be seen as an emotion linked to the ability to engage in fairly sophisticated forms of planning. I also suggest that this has an impact on Prior’s claim that the idea of points in time plays no fundamental role in the semantic analysis of tenses. (shrink)

My dissertation puts forward a critique of the phenomenal intentionality theory (PIT). According to standard accounts of PIT, all genuine intentionality is either identical to or partly grounded in phenomenal consciousness. I argue that it is a conceptually significant mistake to construe conscious experiences in terms of token mental states that instantiate phenomenal properties. This mistake is predicated on ignoring an important difference in the temporal character—what I call the “temporal shape”—between states and properties as opposed to conscious experiences. States (...) and properties lack a temporal shape, but conscious experience has a temporal shape. Thus, in order to adequately capture our phenomenology of temporality we need a mental ontology that adequately reflects this distinction. A second aim of this dissertation is to defend a mereological account of phenomenal intentionality, which says that phenomenality and intentionality are related by being proper parts of a first-personal, subjective, mental event. On this approach, the conditions of satisfaction for a subject’s first-personal, subjective, mental event just are the conditions of satisfaction for phenomenal intentionality. I explore the theoretical grounds for a mereological account of phenomenal intentionality and conclude that it does a better job of explaining difficult cases like the problem of unconscious thought (e.g., your belief that “grass is green”). Thus, we have prima facie support for a mereological account of phenomenal intentionality exactly where competing accounts fail. (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)
