Drugs used to provide improvement of cognitive functioning have been shown to be effective in healthy individuals. It is sometimes assumed that the use of these drugs constitutes cheating in an academic context. We examine whether this assumption is ethically sound. Beyond providing the most up-to-date discussion of modafinil use in an academic context, this contribution includes an overview of the safety of modafinil use in greater depth than previous studies addressing the issue of cheating. Secondly, we emphasize two crucial, (...) but hitherto nearly overlooked, nuances to the issues: the potential for modafinil to decrease inequality and disadvantage in academic settings, and the fact that how modafinil is used dramatically impacts its effects on health, coercion, fairness, authenticity and effort. Finally, we explicitly defend the position that there are no qualitatively morally relevant differences between modafinil use and other enhancement modalities; any such differences are in degree,...

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: -/- The main aim of this review will be to assess the effects of changing practitioner empathy or patient expectations for all conditions. The main objective is to conduct a systematic review of randomised trials where the intervention involves manipulating either (a) practitioner empathy or (b) patient expectations, or (c) both.

I argue against pessimistic readings of the Buddhist tradition on which unawakened beings invariably have lives not worth living due to a preponderance of suffering (duḥkha) over well-being.

Non-Archimedean population axiologies – also known as lexical views – claim (i) that a sufficient number of lives at a very high positive welfare level would be better than any number of lives at a very low positive welfare level and/or (ii) that a sufficient number of lives at a very low negative welfare level would be worse than any number of lives at a very high negative welfare level. Such axiologies are popular because they can avoid the (Negative) Repugnant (...) Conclusion and satisfy the adequacy conditions given in the central impossibility result in population axiology due to Gustaf Arrhenius. I provide a novel argument against them which appeals to the way that good and bad lives can intuitively outweigh one other. (shrink)

I argue for the possibility of an extremely intimate connection between the emotional content of the music and the emotional state of the person who produces that music. Under certain specified conditions, the music may not just influence, but also partially constitute the musician’s emotional state.

This paper examines the causal basis of our ability to attribute emotions to music, developing and synthesizing the existing arousal, resemblance and persona theories of musical expressivity to do so. The principal claim is that music hijacks the simulation mechanism of the brain, a mechanism which has evolved to detect one's own and other people's emotions.

The author proposes a dimensional model of our emotion concepts that is intended to be largely independent of one’s theory of emotions and applicable to the different ways in which emotions are measured. He outlines some conditions for selecting the dimensions based on these motivations and general conceptual grounds. Given these conditions he then advances an 8-dimensional model that is shown to effectively differentiate emotion labels both within and across cultures, as well as more obscure expressive language. The 8 dimensions (...) are: (1) attracted—repulsed, (2) powerful—weak, (3) free—constrained, (4) certain—uncertain, (5) generalized—focused, (6) future directed—past directed, (7) enduring—sudden, (8) socially connected—disconnected.

Maximize Expected Choiceworthiness (MEC) is a theory of decision-making under moral uncertainty. It says that we ought to handle moral uncertainty in the way that Expected Value Theory (EVT) handles descriptive uncertainty. MEC inherits from EVT the problem of fanaticism. Roughly, a decision theory is fanatical when it requires our decision-making to be dominated by low-probability, high-payoff options. Proponents of MEC have offered two main lines of response. The first is that MEC should simply import whatever are the best solutions (...) to fanaticism on offer in decision theory. The second is to propose statistical normalization as a novel solution on behalf of MEC. This paper argues that the first response is open to serious doubt and that the second response fails. As a result, MEC appears significantly less plausible when compared to competing accounts of decision-making under moral uncertainty, which are not fanatical. (shrink)

It is an important feature of creatures like us that our various motivations compete for control over our behaviour, including mental behaviour such as imagining and attending. In large part, this competition is adjudicated by the stimulation of affect — the intrinsically pleasant or unpleasant aspects of experience. In this paper I argue that the motivation-affect system controls a sub-type of attention called 'alerting attention' to bring various goals and stimuli to consciousness and thereby prioritize those contents for action. This (...) view allows me to flesh out the global workspace theory of consciousness, as well as some of the phenomenal characteristics of conscious experience. (shrink)

If we were to connect two individuals’ brains together, how would this affect the individuals’ conscious experiences? In particular, it is possible for two people to share any of their conscious experiences; to simultaneously enjoy some token experiences while remaining distinct subjects? The case of the Hogan twins—craniopagus conjoined twins whose brains are connected at the thalamus—seems to show that this can happen. I argue that while practical empirical methods cannot tell us directly whether or not the twins share conscious (...) experiences, considerations about the locality of content processing in the brain entails that they most likely do so.

This book defends Aestheticism- the claim that everything is aesthetically valuable and that a life lived in pursuit of aesthetic value can be a particularly good one. Furthermore, in distilling aesthetic qualities, artists have a special role to play in teaching us to recognize values; a critical component of virtue. I ground my account upon an analysis of aesthetic value as ‘objectified final value’, which is underwritten by an original psychological claim that all aesthetic values are distal versions of practical (...) values. This is followed by systematic accounts of beauty, sublimity, comedy, drama, and tragedy, as well as appendix entries on the cute, the cool, the kitsch, the uncanny, the horrific, the erotic, and the furious.

In this article we examine obsessive compulsive disorder (OCD). We examine and reject two existing models of this disorder: the Dysfunctional Belief Model and the Inference‐Based Approach. Instead, we propose that the main distinctive characteristic of OCD is a hyperactive sub‐personal signal of being in error, experienced by the individual as uncertainty about his or her intentional actions (including mental actions). This signalling interacts with the anxiety sensitivities of the individual to trigger conscious checking processes, including speculations about possible harms. (...) We examine the implications of this model for the individual's capacity to control his or her thoughts. (shrink)

This paper is an exposition and evaluation of the Agustín Rayo's views about the epistemology and metaphysics of mathematics, as they are presented in his book The Construction of Logical Space.

The literature on the venerable aesthetic category of the sublime often provides us with lists of sublime phenomena — mountains, storms, deserts, volcanoes, oceans, the starry sky, and so on. But it has long been recognized that what matters is the experience of such objects. We then find that one of the most consistent claims about this experience is that it involves an element of fear. Meanwhile, the recognition of the sublime as a category of aesthetic appreciation implies that attraction, (...) admiration or pleasure is also present.1However, there is also a sense of fear and attraction when we watch car chases or fights. Neither of these is an occasion for the sublime so much as a visceral sort of excitement.2 As .. (shrink)

The fear of death resists philosophical attempts at reconciliation. Building on theories of emotion, I argue that we can understand our fear as triggered by a de se mode of thinking about death which comes into conflict with our will to live. The discursive mode of philosophy may help us to avoid the de se mode of thinking about death, but it does not satisfactorily address the problem. I focus instead on the voluntary diminishment of one’s will to live. I (...) argue that we can encourage a natural tendency for the will to live to decline as we approach death. I then consider two objections: Is not the will to live too fundamental for us to control? And even if we can control it, would not a declining will to live result in a general despair that it is better to resist? I argue that both of these objections can be overcome. (shrink)

I argue that while the feeling of bodily responses is not necessary to emotion, these feelings contribute significant meaningful content to everyday emotional experience. Emotional bodily feelings represent a ‘state of self’, analysed as a sense of one's body affording certain patterns of interaction with the environment. Recognising that there are two sources of intentional content in everyday emotional experience allows us to reconcile the diverging intuitions that people have about emotional states, and to understand better the long-standing debate between (...) bodily feeling-based and appraisal-based theories of emotion.

This paper contrasts individual and collective listening to music, with particular regard to the expressive qualities of music. In the first half of the paper a general model of joint attention is introduced. According to this model, perceiving together modifies the intrinsic structure of the perceptual task, and encourages a convergence of responses to a greater or lesser degree. The model is then applied to music, looking first at the silent listening situation typical to the classical concert hall, and second (...) the noisy listening situation typical to rock or jazz concerts.

In this paper I present an account of musical arousal that takes into account key demands of formalist philosophers such as Peter Kivy and Nick Zangwill. Formalists prioritise our understanding and appreciation of the music itself. As a result, they demand that any feelings we have in response to music must be directed at the music alone, without being distracted by non-musical associations. To accommodate these requirements I appeal to a mechanism of contagion which I synthesize with the expectation-based arousal (...) mechanism proposed by Leonard Meyer. This account connects musical expressivity and arousal in a way that formalists have rejected, but I argue that it provides the best explanation of our observations of listener responses while also focusing on the music itself.

This article defends a persona theory of musical expressivity. After briefly summarising the major arguments for this view, it applies persona theory to the issue of whether music can express complex emotions. The expression of jealousy is then discussed by analysis of two examples from Piazzolla and Janacek.

In this chapter I analyse group flow: a state in which performers report intense interpersonal absorption with the music and each other. I compare group flow to individual flow, and argue that the same essential structure can be discerned. I argue that group flow does not justify an anti-representationalist enactivist interpretation. However, I claim that the cognitive task in which the music is produced is irreducibly collective.

This paper develops a mechanistic account of basic mental agency by identifying similarities between two of its major exemplars: endogenous attention and imagination. Five key similarities are identified: i) that both capacities are driven by currently prioritised goals that are either person-level or apt to become person-level. ii) that both deliver their outputs to the working memory iii) that both range across all and only conceptual contents; iv) that both proceed under the guidance of norms and/or habits; and v) that (...) both directly activate rather than inhibit content. These five features are consolidated by proposing that basic mental agency is essentially the power to call for conceptual content and hold it within our working memories. (shrink)

This article reviews some of the ways in which philosophical problems concerning music can be informed by approaches from the cognitive sciences (principally psychology and neuroscience). Focusing on the issues of musical expressiveness and the arousal of emotions by music, the key philosophical problems and their alternative solutions are outlined. There is room for optimism that while current experimental data does not always unambiguously satisfy philosophical scrutiny, it can potentially support one theory over another, and in some cases allow us (...) to synthesize or reject traditional philosophical differences.

I claim that the significance of comic works to influence our attitudes is limited by the conditions under which we find things funny. I argue that we can only find something funny if we regard it as norm-violating in a way that doesn’t make certain cognitive or pragmatic demands upon us. It is compatible with these conditions that humour reinforces our attitude that something is norm-violating. However, it is not compatible with these conditions that, on the basis of finding it (...) funny, we come to reject some existing attitude. Such a rejection would require that we recognize our attitude as norm-violating in a way that has pragmatic force. Thus if a humorous work reveals the absurdity of something, we can either find it funny and not have our attitudes significantly influenced, or else be significantly influenced but not find it funny.

This article considers the contemporary effective altruism (EA) movement from a classical Indian Buddhist perspective. Following barebones introductions to EA and to Buddhism (sections one and two, respectively), section three argues that core EA efforts, such as those to improve global health, end factory farming, and safeguard the long-term future of humanity, are futile on the Buddhist worldview. For regardless of the short-term welfare improvements that effective altruists impart, Buddhism teaches that all unenlightened beings will simply be reborn upon their (...) deaths back into the round of rebirth (samsāra), which is held to be undesirable due to the preponderance of duhkha (unsatisfactoriness, dis-ease, suffering) over well-being that characterizes unenlightened existence. This is the samsāric futility problem. Although Buddhists and effective altruists disagree about what ultimately helps sentient beings, section four suggests that Buddhist-EA dialogue nonetheless generates mutually-instructive insights. Buddhists – including contemporaries, such as those involved in Socially Engaged Buddhism – might take from EA a greater focus on explicit prioritization research, which seeks knowledge of how to do the most good we can, given our finite resources. EA, for its part, has at least two lessons to learn. First, effective altruists have tended to assume that the competing accounts of welfare converge in their practical implications. The Buddhist conception of the pinnacle of welfare as a state free from duhkha and, correspondingly, the Buddhist account of the path that leads to this state weigh against this assumption. Second, contrasting Buddhist with effective altruist priorities shows that descriptive matters of cosmology, ontology, and metaphysics can have decisive practical implications. If EA wants to give a comprehensive answer to its guiding question – “how can we do the most good?” – it must argue for, rather than merely assume, the truth of secular naturalism. (shrink)

This paper identifies a tension between the commitment to forming rationally justified emotions and the happy life. To illustrate this tension I begin with a critical evaluation of the positive psychology technique known as ‘gratitude training’. I argue that gratitude training is at odds with the kind of critical monitoring that several philosophers have claimed is regulative of emotional rationality. More generally, critical monitoring undermines exuberance, an attitude that plays a central role in contemporary models of the happy life. Thus, (...) prominent notions of what it takes to maintain emotion rationality and what it takes to maintain happiness are in tension. To resolve this tension, I argue that some people have good reason to depreciate critical monitoring—even while maintaining the requirement of emotion rationality that we be sensitive to facts about how our concerns are faring.

This dissertation aims to revive wave theory in the philosophy of sound. Wave theory identifies sounds with compression waves. Despite its wide acceptance in the scientific community as the default position, many philosophers have rejected wave theory and opted for different versions of distal theory instead. According to this current majority view, a sound has its stationary location at its source. I argue against this and other alternative philosophical theories of sound and develop wave theory into a more defensible form. (...) Philosophers of sound tend to emphasise how sounds are experienced to be in their arguments. Most often, it is assumed that that which appears to be a distally located bearer of auditory properties in an auditory experience is a sound. Chapter 1 argues that if this distal entity is the sound source instead, many of the existing theories of sound will be severely affected. Chapter 2 discusses auditory perception and criticises the common assumption that we hear non-sound entities in virtue of hearing sounds. I show that this assumption begs the question against certain theories of sound and that the contrary view that sound sources can be directly heard is more plausible. If sound sources can be directly heard, then features commonly attributed to sounds based on auditory experiences might rather be features of sound sources. I examine eight of such features in Chapter 3. Only four of them survive. Chapters 4 and 5 review the existing theories of sound. After a taxonomy of existing theories of sound, each theory is criticised one-by-one. Some of them are problematic precisely because they rely on the implausible assumption that that which appears to be distally located in an auditory experience is a sound rather than a sound source. Lastly, Chapter 6 focuses on wave theory. It begins with two positive arguments for wave theory in general, followed by my replies to two common objections in the literature. I then move on to develop my version of wave theory. There are two core aspects of my view. The first one is a metaphysics of compression waves; the second is an account of what it is to hear compression waves. After comparing my view with a similar theory, I demonstrate the explanatory power of my view in two steps. First, the eight commonly accepted features of sounds examined in Chapter 3 are revisited. It turns out that my view can accommodate all of them. Second, explanations for four special sound-related phenomena are offered at the end of the chapter. I conclude in the last chapter with the suggestion that, as a philosopher, the best way to defend wave theory is to offer a better understanding of auditory perception which explains how compression waves are experienced.

I believe the first thing to say about value is that it is something that we do. We value things. There is no value out there independent of valuing beings. Thi.

A summary of The Emotional Mind: A Control Theory of Affective States is presented: I claim that a convincing account of the emotions requires a rethink of how the mind as a whole is structured. I provide this reconceptualization by introducing a fundamental type of mental concept called “valent representation" and then systematically elaborating this fundamental type in stages. In this way, accounts are provided of the various sorts of affective states ranging from pains and pleasures to character traits.

I defend the claim that fictional narratives provide cognitive benefits to readers in virtue of helping them to understand character. Fictions allow readers to rehearse the skill of selecting and organizing into narratives those episodes of a life that reflect traits or values. Two further benefits follow: first, fictional narratives provide character models that we can apply to real-life individuals (including ourselves), and second, fictional narratives help readers to reflect on the value priorities that constitute character. I defend the plausibility (...) of these cognitive benefits against certain worries raised by Gregory Currie and Peter Goldie. (shrink)

In this brief comment on a target article by Koelsch et al., I argue that emotions are more sensitive to context than other affective states.

I examine the role that the musical instrument plays in shaping a performer's expressive activity and emotional state. I argue that the historical development of the musical instrument has fluctuated between two key values: that of sharing with other musicians, and that of creatively exploring new possibilities. I introduce 'the mood organ'- a sensor-based computer instrument that automatically turns signals of the wearer's emotional state into expressive music.

William James wrote that the life of religion “consists of the belief that there is an unseen order, and that our supreme good lies in harmoniously adjusting ourselves thereto.” Naturalism organizes our experiences of the universe within a science-grounded philosophical and/or religious framework aligning it with what is supremely good for our lives. This article describes a science-grounded specific “Framework of Spirituality” identifying part of this unseen order that opens a “spiritual core” within persons as a source of healing and (...) happiness. A cognitive behavioral therapy (CBT) expanded process shows how experiences of human worth and dignity are keys to this new awareness and provides speculation for a brain function and evolutionary explanation. Details of this knowledge are related to various perspectives and authors of naturalism—scientific, religious, ecstatic, and ecological—to contribute to a future direction for the understanding, development, and further expression of naturalism.

This paper presents a simple pair of first-order theories that are not definitionally (nor Morita) equivalent, yet are mutually conservatively translatable and mutually 'surjectively' translatable. We use these results to clarify the overall geography of standards of equivalence and to show that the structural commitments that theories make behave in a more subtle manner than has been recognized.

Issues of reliability are claiming center-stage in the epistemology of machine learning.

A good account of the agnostic attitude of Suspending Judgement should explain how it can be rendered more or less rational/justified according to the state of one's evidence – and one's relation to that evidence. I argue that the attitude of suspending judgement whether p constitutively involves having a belief; roughly, a belief that one cannot yet tell whether or not p. I show that a theory of suspending that treats it as a sui generis attitude, wholly distinct from belief, (...) struggles to account for how suspension of judgement can be rendered more or less rational (or irrational) by one's evidence. I also criticise the related idea that suspension essentially requires an 'Inquiring Attitude'. I show how a belief-based theory, in contrast, neatly accounts for the rational and epistemic features of suspending and so neatly accounts for why an agnostic has a genuine neutral opinion concerning the question whether p, as opposed to simply having no opinion.

An ethical theory is alienating if accepting the theory inhibits the agent from fitting participation in some normative ideal, such as some ideal of integrity, friendship, or community. Many normative ideals involve non-consequentialist behavior of some form or another. If such ideals are normatively authoritative, they constitute counterexamples to consequentialism unless their authority can be explained or explained away. We address a range of attempts to avoid such counterexamples and argue that consequentialism cannot by itself account for the normative authority (...) of all plausible such ideals. At best, consequentialism can find a more modest place in an ethical theory that includes non-consequentialist principles with their own normative authority. (shrink)

I present two arguments that aim to establish logical limits on what we can know. More specifically, I argue for two results concerning what we can know about questions that we cannot answer. I also discuss a line of thought, found in the writings of Pierce and of Rescher, in support of the idea that we cannot identify specific scientific questions that will never be answered.

This paper argues that the current discourse on epistemic injustice in social epistemology itself perpetuates epistemic injustice, namely hermeneutic injustice with regards to class and classism. The main reason is that debates on epistemic injustice have foremost focussed on issues related to gender, race, and disability while mostly ignoring class issues. I suggest that this is due to (largely unwarranted) fears about looming class reductionism. More importantly, this is omission is not innocuous, but problematic insofar as it has an unlikely (...) ally in neoliberal propaganda which features as one main goal stifling class consciousness. While this “allyship” is unwitting, this presents grounds for the discourse of epistemic injustice to consider re-centring class issues and classism. (shrink)

I present an argument against the thesis of Uniqueness and in favour of Permissivism. Counterexamples to Uniqueness are provided, based on ‘Safespot’ propositions – i.e. a proposition that is guaranteed to be true provided the subject adopts a certain attitude towards it. The argument relies on a plausible principle: (roughly stated) If S knows that her believing p would be a true belief, then it is rationally permitted for S to believe p. One motivation for denying this principle – viz. (...) opposition to ‘epistemic consequentialism’ – is briefly discussed. The principle is extended to cover degrees of belief and compared with a couple of other well-known constraints on rational degrees of belief. (shrink)

This paper examines the evolution of Edmund Husserl’s theory of perceptual occlusion. This task is accomplished in two stages. First, I elucidate Husserl’s conclusion, from his 1901 Logical Investigations, that the occluded parts of perceptual objects are intended by partial signitive acts. I focus on two doctrines of that account. I examine Husserl’s insight that signitive intentions are composed of Gehalt and I discuss his conclusion that signitive intentions sit on the continuum of fullness. Second, the paper discloses how Husserl (...) transforms his 1901 philosophy in his 1913 revisions to the Sixth Logical Investigation, affirming that the occluded parts of perceptual objects are intended by empty contiguity acts. I demonstrate how he overturns the two core doctrines of his theory from the Investigations in these revisions, claiming that empty intentions are not composed of Gehalt and asserting that those acts break with the continuum of fullness. Husserl implements these changes to solve problems that arise from his recognition of two new kinds of intentions; darker and completely dark acts. Finally, in the conclusion, I cash out this analysis, by indicating that, in 1913, Husserl transforms his theory of fulfillment on the basis of his new insights about empty acts. (shrink)

Mathematicians, physicists, and philosophers of physics often look to the symmetries of an object for insight into the structure and constitution of the object. My aim in this paper is to explain why this practice is successful. In order to do so, I present a collection of results that are closely related to (and in a sense, generalizations of) Beth’s and Svenonius’ theorems.

In this paper I will offer a comprehensive defense of the safety account of knowledge against counterexamples that have been recently put forward. In Sect. 2, I will discuss different versions of safety, arguing that a specific variant of method-relativized safety is the most plausible. I will then use this specific version of safety to respond to counterexamples in the recent literature. In Sect. 3, I will address alleged examples of safe beliefs that still constitute Gettier cases. In Sect. 4, (...) I will discuss alleged examples of unsafe knowledge. In Sect. 5, I will address alleged cases of safe belief that do not constitute knowledge for non-Gettier reasons. My overall goal is to show that there are no successful counterexamples to robust anti-luck epistemology and to highlight some major presuppositions of my reply. (shrink)

In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject.

This paper accomplishes two tasks. First, I examine in detail Edmund Husserl’s earliest philosophy of surrogates, as it is found in his 1890 “On the Logic of Signs ”. I analyze his psychological and logical investigations of surrogates, where the former is concerned with explaining how these signs function and the latter with how they do so reliably. His differentiation of surrogates on the basis of their genetic origins and degrees of necessity is discussed. Second, the historical importance of this (...) text is disclosed by showing how Semiotic serves as both the inspiration for, and the foil to, Husserl’s 1901 First Logical Investigation. Husserl not only adopts the idea that linguistic signs can function via association, but also maintains that such signs can motivate me to execute one of two experiences. The key difference between the texts is that Husserl abandons his theory of surrogates in 1901, instead holding that I can experience absent objects by means of empty intentions. The reasons why Husserl found it necessary to transform this tenet of his philosophy are discussed at length. (shrink)

Some philosophers believe that when epistemic peers disagree, each has an obligation to accord the other's assessment the same weight as her own. I first make the antecedent of this Equal-Weight View more precise, and then I motivate the View by describing cases in which it gives the intuitively correct verdict. Next I introduce some apparent counterexamples – cases of apparent peer disagreement in which, intuitively, one should not give equal weight to the other party's assessment. To defuse these apparent (...) counterexamples, an advocate of the View might try to explain how they are not genuine cases of peer disagreement. I examine David Christensen's and Adam Elga's explanations and find them wanting. I then offer a novel explanation, which turns on a distinction between knowledge from reports and knowledge from direct acquaintance. Finally, I extend my explanation to provide a handy and satisfying response to the charge of self-defeat. (shrink)

The theory of collective agency and intentionality is a flourishing field of research, and our understanding of these phenomena has arguably increased greatly in recent years. Extant theories, however, are still ill-equipped to explain certain aspects of collective intentionality. In this article we draw attention to two such underappreciated aspects: the failure of the intentional states of collectives to supervene on the intentional states of their members, and the role of non-human factors in collective agency and intentionality. We propose a (...) theory of collective intentionality which builds on the ‘interpretationist’ tradition in metasemantics and the philosophy of mind as initiated by David Lewis and recently developed further by Robbie Williams. The collective-level analogue of interpretationism turns out to look different in some ways from the individual-level theory, but is well-suited to accommodating phenomena such as hybrid collective intentionality. Complemented with Kit Fine’s theory of variable embodiment, such a theory also provides a diachronic account of intentional collectives. (shrink)
