Nietzsche offers us an account of how different drives interact with one another; it is rich but also appears to risk the homunculus fallacy. Competing attempts to deflect this charge on his behalf share an implicit consensus about the ‘epistemic ends’ of the account: they assume Nietzsche is trying to provide true explanations of psychological phenomena. I argue against this consensus. I claim that Nietzsche's characterisations of drive interaction are to be taken as fictive and are not intended to have (...) explanatory value. They nevertheless facilitate genuine epistemic achievement. Drawing on Catherine Elgin's account of the epistemic role of idealised models in science, I argue that Nietzsche's account of drive interaction is a ‘model of the mind’ that, despite relying on falsehoods, can exemplify features of our psychology that aid us in making novel predictions. We then see that Nietzsche neatly sidesteps the homunculus fallacy; we can further understand more fully what Nietzsche hopes his drive psychology will teach us. We can now resolve, for example, outstanding interpretative puzzles about the relationship between psychic integration and Nietzsche’s distinctive notion of spiritual health. (shrink)

I develop a new schema for analysis of dispositions in terms of structural equations. This schema provides the means to respond to a host of problems that have been posed for other proposals, including the problem of masks, alters, mimickers, tricks, conjunctive multi-track dispositions and dispositional degrees. In the development of this new schema, I will employ structural modelling techniques to highlight features of the problem cases, thereby revealing the utility of these techniques to ongoing discussion.

We think we know what healers do: they build on patients' irrational beliefs and treat them in a 'symbolic' way. If they get results, it's thanks to their capacity to listen, rather than any influence on a clinical level. At the same time, we also think we know what modern medicine is: a highly technical and rational process, but one that scarcely listens to patients at all. In this book, ethnopsychiatrist Tobie Nathan and philosopher Isabelle Stengers argue that this commonly (...) posed opposition between traditional and modern medicine is misleading. They show instead that healers are interesting precisely because they don't listen to patients, using techniques of 'divination' rather than 'diagnosis'. Healers construct genuine therapeutic strategies by identifying the origins of symptoms in external forces, outside of the mind of the sufferer, and in this regard African healers are virtuosos. Though it may claim otherwise, modern medicine, for its part, is characterised by empiricism rather than rationality. What appears to be the pursuit of rationality is ultimately only a means to dismiss and exclude other forms of treatment. Blurring the distinctions between traditional and modern practices and drawing on perspectives from across the globe, this ethnopsychiatric manifesto encourages us to think in radically new ways about illness, challenging accepted notions on the relationship between sufferer and symptom. It will be of great interest to those working in medicine and healthcare, as well as anthropologists, social scientists and those in the humanities more broadly. (shrink)

The fairy tale The Three Princes of Serendip can be taken to be allegorical of not only chance discovery (serendipity) but of other aspects of scientific discovery as well. Just as Horace Walpole coined serendipity, so can the term bahramdipity be derived from the tale and defined as the cruel suppression of a serendipitous discovery. Suppressed, unpublished discoveries are designated nulltiples. Several examples are presented to make the case that bahramdipity is an existent aspect of scientific discovery. Other examples of (...) non-ideal scientific research and discovery are provided in order to contrast and clarify the meaning and use of bahramdipity. Additional allegories of scientific discovery are taken from the tale and a hope for the strengthening of scientific integrity is expressed. (shrink)

Humanity stands at a precipice. -/- Our species could survive for millions of generations — enough time to end disease, poverty, and injustice; to reach new heights of flourishing. But this vast future is at risk. With the advent of nuclear weapons, humanity entered a new age, gaining the power to destroy ourselves, without the wisdom to ensure we won’t. Since then, these dangers have only multiplied, from climate change to engineered pandemics and unaligned artificial intelligence. If we do not (...) act fast to reach a place of safety, it may soon be too late. -/- The Precipice explores the science behind the risks we face. It puts them in the context of the greater story of humanity: showing how ending these risks is among the most pressing moral issues of our time. And it points the way forward, to the actions and strategies we can take today to safeguard humanity’s future. (shrink)

In this report I provide an introduction to the burgeoning field of hypercomputation – the study of machines that can compute more than Turing machines. I take an extensive survey of many of the key concepts in the field, tying together the disparate ideas and presenting them in a structure which allows comparisons of the many approaches and results. To this I add several new results and draw out some interesting consequences of hypercomputation for several different disciplines.

This article considers the nature of communitarian thought in late twentieth century Anglo-American political philosophy. It argues that communitarianism arose out of a critique of modernist theories of justice such as that of John Rawls shared by a group of writers committed to idealist principles that emphasised narrative approaches to the study of political thought, the importance of historical context, and popular participation in political life. It then focuses on one particular American strand of communitarian thought, exemplified by the work (...) of Michael Walzer and Michael Sandel, which draws on a tradition of radical democracy and, in so doing, helps both to create and to transform a new American republicanism. An important connection between Walzer and Sandel is that they share the view that egalitarian politics must draw on shared traditions of social criticism rather than on the abstract individualism that they associate with Rawls. A key difference is that Walzer's vision of American life is pluralist and enthusiastic about difference, whereas Sandel's is republican and concerned above all with fostering civic virtue and identification with the state and political community.

Graham Priest has argued that the fruits of classical set theory can be obtained by naive means through a puzzling piece of reasoning often known as the bootstrapping argument. I will demonstrate that the bootstrapping involved is best understood as viciously circular and thus, that these fruits remain forbidden. The argument has only one rehearsal in print and it is quite subtle. This paper provides reconstruction of the argument based on Priest and attempts some fixes and alternative construals to get (...) around some elementary problems. Despite these efforts, the argument remains unconvincing. (shrink)

In this book, Toby Svoboda develops and defends a Kantian environmental virtue ethic, challenging the widely-held view that Kant's moral philosophy takes an instrumental view toward nature and animals and has little to offer environmental ethics. On the contrary, Svoboda posits that there is good moral reason to care about non-human organisms in their own right and to value their flourishing independently of human interests, since doing so is constitutive of certain virtues. Svoboda argues that Kant’s account of indirect (...) duties regarding nature can ground a compelling environmental ethic: the Kantian duty to develop morally virtuous dispositions strictly proscribes unnecessarily harming organisms, and Svoboda argues that this duty compels us to act in ways that benefit non-human organisms, given that doing so can enhance one’s virtues. Svoboda’s argument engages the recent literature on environmental virtue and provides an original argument for an environmental virtue ethic firmly rooted in Kant’s moral philosophy. (shrink)

This paper argues in favor of a particular account of decision‐making under normative uncertainty: that, when it is possible to do so, one should maximize expected choice‐worthiness. Though this position has been often suggested in the literature and is often taken to be the ‘default’ view, it has so far received little in the way of positive argument in its favor. After dealing with some preliminaries and giving the basic motivation for taking normative uncertainty into account in our decision‐making, we (...) consider and provide new arguments against two rival accounts that have been offered—the accounts that we call ‘My Favorite Theory’ and ‘My Favorite Option’. We then give a novel argument for comparativism—the view that, under normative uncertainty, one should take into account both probabilities of different theories and magnitudes of choice‐worthiness. Finally, we further argue in favor of maximizing expected choice‐worthiness and consider and respond to five objections. (shrink)

It is a commonplace that scientific inquiry makes extensive use of probabilities, many of which seem to be objective chances, describing features of reality that are independent of our minds. Such chances appear to have a number of paradoxical or puzzling features: they appear to be mind-independent facts, but they are intimately connected with rational psychology; they display a temporal asymmetry, but they are supposed to be grounded in physical laws that are time-symmetric; and chances are used to explain and (...) predict frequencies of events, although they cannot be reduced to those frequencies. This book offers an accessible and non-technical introduction to these and other puzzles. Toby Handfield engages with traditional metaphysics and philosophy of science, drawing upon recent work in the foundations of quantum mechanics and thermodynamics to provide a novel account of objective probability that is empirically informed without requiring specialist scientific knowledge.

Some authors have called for increased research on various forms of geoengineering as a means to address global climate change. This paper focuses on the question of whether a particular form of geoengineering, namely deploying sulfate aerosols in the stratosphere to counteract some of the effects of increased greenhouse gas concentrations, would be a just response to climate change. In particular, we examine problems sulfate aerosol geoengineering (SAG) faces in meeting the requirements of distributive, intergenerational, and procedural justice. We argue (...) that SAG faces obstacles to meeting the requirements of all three considered kinds of justice, because its impacts can harm some persons and communities much more than others; it poses serious risks to future generations; and SAG is especially prone to unilateral implementation. While we do not claim that SAG ought not to be implemented, we argue that it is the responsibility of proponents of SAG to recognize and address these ethical obstacles before advocating its implementation.

The emerging field of comparative political theory (CPT) seeks to expand our understanding of politics through intercultural dialogues between diverse systems of political thought. CPT acknowledges diverse modes of political understanding, yet the field is still methodologically focused on textual forms of political practice and learning. I argue that the privileging of political literature in CPT has been inherited from orthodox political theory and the history of political thought and that the prioritizing of text over oral and enactive practices places (...) constraints on intercultural dialogue. First, methodological focus on texts inhibits dialogue with Indigenous traditions that do not prioritize text in the same way or to the same extent in the reproduction of political culture. Second, the incorporation of oral traditions tends to conflate orality with text in ways that obfuscate the contribution of enactive performance. One result of these methodological oversights is that CPT risks recapitulating some of the historical exclusionary logics that it seeks to overcome. (shrink)

Part–whole causation (PWC) is the thesis that some causes are part of their effects. PWC has been objected to because of its incompatibility with the criterion that causes not be spatially included within their effects and the criterion that causes and effects are ontologically distinct in some sense. This paper serves to undermine the sufficiency of these ways of objecting to PWC by showing that for each criterion either cause-effect relationships need not satisfy it or part–whole relationships can. A case-study (...) of the collapse of Bridge 9340 is employed to facilitate the discussion. (shrink)

It has often been noted that there is some tension between engaging in decision-making and believing that one’s choices might be predetermined. The possibility that our choices are predetermined forces us to consider, in our decisions, act-state pairs which are inconsistent, and hence to which we cannot assign sensible utilities. But the reasoning which justifies two-boxing in Newcomb’s problem also justifies associating a non-zero causal probability with these inconsistent act-state pairs. Put together these undefined utilities and non-zero probabilities entail that (...) expected utilities are undefined whenever it is a possibility that our choices are predetermined. There are three ways to solve the problem, but all of them suffer serious costs: always assume that, contrary to our evidence, the outcome of our present decision-making is not predetermined; give up the reasoning that justifies unconditional two-boxing in Newcomb’s problem; or allow epistemically impossible outcomes to contribute to expected utility, leading to the wrong results in a series of cases introduced by Ahmed :665–685, 2014a, Evidence, decision and causality, Cambridge University Press, Cambridge, 2014b). However they choose to respond, causal decision theorists cannot remain silent: the intuitive tension between decision-making and the possibility of predetermination can be made precise, and resolving it will require giving up something. Causal decision theorists have a predetermination problem. (shrink)

Shamatha, Transcendental, and Stillness Meditation are said to aim for “contentless” experiences, where mental content such as thoughts, perceptions, and mental images is absent. Silence is understood to be a central feature of those experiences. The main source of information about the experiences is texts by experts from within the three traditions. Previous research has tended not to use an explicit scientific method for selecting and reviewing expert texts on meditation. We have identified evidence synthesis as a robust and transparent (...) method that is suitable for this purpose. In this paper we use evidence synthesis based on expert texts to examine silence/quietness as a feature of the contentless experiences in the three practices. Objective criteria were used to select a sample of 135 expert texts. A database containing the expert descriptions of the meditation techniques and experiences was produced by extracting the relevant material from the publications and coding that material to differentiate individual features. The database, which forms part of the Supplementary Material for this paper, identifies each feature of the contentless experiences referred to in the expert texts, including silence/quietness. Our key finding is that the experts indicate silence/quietness has a particular connection with stillness, and the absence of concepts, mental activity/noise, thoughts, and disturbance. Further analysis leads to the following insights. The silence/quietness reflects the absence of thoughts and sounds, and this fits neatly with a conception of silence/quietness as the absence of internal and external noise. In some cases the terms silence and quietness may also reflect the absence of other disturbances such as non-auditory perceptions, mental images, and negative feelings. That would fit with a conception of silence/quietness as complete calm or absence of disturbance. It is not clear from the expert texts how silence/quietness is distinct from other features such as stillness that also reflect the absence of disturbances. As a separate matter, silence/quietness has connections with all the other features of the contentless experiences, but the closeness of the connections varies. Our work uncovers fine distinctions and ambiguities which lead to new research questions that can be explored in future studies. (shrink)

This paper appeals to certain popular doctrines about human welfare and morality to offer a new response to the problem of hell. In particular, I contend that the combination of desire satisfactionism, a subjective theory about welfare, with an objective theory of morality leads to a surprisingly intuitive and compelling argument for the consistency of the post-mortem punishment of people in hell with the existence of an omniperfect God. In fact, under these conditions, the existence of such a divine being (...) may actually require that there be at least some type of hell/post-mortem punishment. Finally, I suggest that positing the existence of hell can strengthen desire satisfactionism against an objection tied to base or immoral desires. (shrink)

Drawing on theoretical arguments from the psychology discipline, we investigate the implications of employee entitlement in organizational settings. Specifically, we utilize workplace engagement theory to suggest that due to their skewed sense of deservingness, employees high in entitlement are less likely to experience workplace engagement. Furthermore, the negative relationship between employee entitlement and workplace engagement is strengthened when ethical leadership is low, yet mitigated when ethical leadership is high. Finally, we predict that under conditions of low ethical leadership, reductions in (...) engagement explain why employee entitlement results in hindered job performance. This mediated effect does not hold when ethical leadership is high. We tested our theoretical model utilizing field data from employees and their direct supervisors in the financial services industry. Our results support our theoretical model. Theoretical and practical implications are discussed. (shrink)

Contentless experience involves an absence of mental content such as thought, perception, and mental imagery. In academic work it has been classically treated as including states like those aimed for in Shamatha, Transcendental, and Stillness Meditation. We have used evidence synthesis to select and review 135 expert texts from within the three traditions. In this paper we identify the features of contentless experience referred to in the expert texts and determine whether the experiences are the same or different across the (...) practices with respect to each feature. We identify 65 features reported or implied in one or more practices, with most being reported or implied in all three. While there are broad similarities in the experiences across the traditions, we find that there are differences with respect to four features and possibly many others. The main difference identified is that Shamatha involves substantially greater attentional stability and vividness. Another key finding is that numerous forms of content are present in the experiences, including wakefulness, naturalness, calm, bliss/joy, and freedom. The findings indicate that meditation experiences described as contentless in the academic literature can in fact involve considerable variation, and that in many and perhaps most cases these experiences are not truly contentless. This challenges classical understandings in academic research that in these so-called contentless experiences all content is absent, and that the experiences are therefore an identical state of _pure consciousness_ or consciousness itself. Our assessment is that it remains an open question whether the experiences aimed for in the three practices should be classed as pure consciousness. Implications of our analysis for neuroscientific and clinical studies and for basic understandings of the practices are discussed. (shrink)

The social contract tradition has been critiqued for harboring ‘domination contracts’ that exclude women, people of color, people with disabilities, and others from political life. In this article, I build on these critical analyses to argue that the liberal ideal of the reasoning and speaking citizen entails the anti-democratic disqualification of ‘silent’ citizens such as young children and many peoples with intellectual disabilities. The liberal veneration of voice and the corollary vilification of silence represent the internal logic of all domination (...) contracts, since it is by comparison to silent children and peoples with disabilities that groups such as women and people of color are viewed as justifiably excluded. I identify two distinct but interacting forms of liberal disqualification: (1) contingent domination contracts, which can be potentially disputed and temporarily resolved by proving a group’s fulfilment of the qualifications of speech and reason; and (2) structural domination contracts, which cannot be resolved for ‘silent’ citizens. Moreover, any viable challenge to a contingent domination contract must centre on the democratic inclusion of silent citizens, which itself will require the reconceptualization and redesign of political processes, as well as workplaces, economies, and other social institutions.

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience with which the spectrum began. Hence the betterness relation admits cycles, threatening either transitivity or asymmetry of the relation. This (...) paper examines recent attempts to block the spectrum argument, using the idea that it is a mistake to affirm that every experience in the spectrum is worse than its predecessor: an alternative hypothesis is that adjacent experiences may be incommensurable in value, or that due to vagueness in the underlying concepts, it is indeterminate which is better. While these attempts formally succeed as responses to the spectrum argument, they have additional, as yet unacknowledged costs that are significant. In order to effectively block the argument in its most typical form, in which the first element is radically inferior to the last, it is necessary to suppose that the incommensurability is particularly acute: what might be called radical incommensurability. We explain these costs, and draw some general lessons about the plausibility of the available options for those who wish to save orthodox axiology from the spectrum argument. (shrink)

Many philosophers have objected to Kant’s account of duties regarding non-human nature, arguing that it does not ground adequate moral concern for non-human natural entities. However, the traditional interpretation of Kant on this issue is mistaken, because it takes him to be arguing merely that humans should abstain from animal cruelty and wanton destruction of flora solely because such actions could make one more likely to violate one’s duties to human beings. Instead, I argue, Kant’s account of duties regarding nature (...) grounds much stronger limitations on how humans may treat non-human animals and flora, since such duties are rooted in the imperfect duty to increase one’s own moral perfection. This duty proscribes actions affecting non-human nature that decrease one’s moral perfection, such as those that cause organisms unnecessary harm. Moreover, the duty to moral perfection prescribes (but does not strictly require) actions affecting non-human nature that increase one’s moral perfection, such as those that benefit organisms. Given this interpretation, I show that, contrary to a widely held view, Kant’s moral philosophy can ground a coherent and robust approach to environmental ethics. (shrink)

It is often claimed that from the moment of conception embryos have the same moral status as adult humans. This claim plays a central role in many arguments against abortion, in vitro fertilization, and stem cell research. In what follows, I show that this claim leads directly to an unexpected and unwelcome conclusion: that natural embryo loss is one of the greatest problems of our time and that we must do almost everything in our power to prevent it. I examine (...) the responses available to those who hold that embryos have full moral status and conclude that they cannot avoid the force of this argument without giving up this key claim.

Necessitarian accounts of the laws of nature meet an apparent difficulty: for them, counterlegal conditionals, despite appearing to be substantive, seem to come out as vacuous. I argue that the necessitarian may use the presuppositions of counterlegal discourse to explain this. If the typical presupposition that necessitarianism is false is made explicit in counterlegal utterances, we obtain sentences such as 'If it turns out that the laws of nature are contingent, then if the laws had been otherwise, then such and (...) such would have been the case', which are non-vacuous and very often true. This goes a long way towards resolving the difficulty for necessitarianism. (shrink)

This paper develops two ideas with respect to dispositional properties: (1) Adapting a suggestion of Sungho Choi, it appears the conceptual distinction between dispositional and categorical properties can be drawn in terms of susceptibility to finks and antidotes. Dispositional, but not categorical properties, are not susceptible to intrinsic finks, nor are they remediable by intrinsic antidotes. (2) If correct, this suggests the possibility that some dispositions—those which lack any causal basis—may be insusceptible to any fink or antidote. Since finks and (...) antidotes are a major obstacle to a conditional analysis of dispositions, these dispositions that are unfinkable may be successfully analysed by the conditional analysis of dispositions. This result is of importance for those who think that the fundamental properties might be dispositions which lack any distinct causal basis, because it suggests that these properties, if they exist, can be analysed by simple conditionals and that they will not be subject to ceteris paribus laws.

Objective chance and morality are rarely discussed together. In this paper, I argue that there is a surprising similarity in the epistemic standing of our beliefs about both objective chance and objective morality. The key similarity is that both of these sorts of belief are undermined -- in a limited, but important way -- by plausible genealogical accounts of the concepts that feature in these beliefs. The paper presents a brief account of Richard Joyce's evolutionary hypothesis of the genealogy of (...) morality, and refines the debunking argument which he consequently mounts against moral beliefs. The evolutionary hypothesis in question suggests that we could easily have failed to believe that moral judgments have a peculiarly categorical force. This aspect of our moral belief, then, is unreliable. The paper then turns to chance, and presents a more speculative hypothesis about the cultural evolution of ideas about chance, as a peculiarly physical and objective form of probability. It is argued that, in the same way that our beliefs about morality could easily have lacked the commitment to inescapable force, our beliefs about chance could easily have lacked various idiosyncratic commitments. By a similar argument then, these aspects of our chance beliefs are unreliable. In the final section of the paper, I review some recent objections to genealogical debunking arguments, due to Roger White and Guy Kahane, showing how the form of argument developed in this paper is immune to these criticisms.

As we understand them, dispositions are relatively uncontroversial 'predicatory' properties had by objects disposed in certain ways. By contrast, powers are hypothetical 'ontic' properties posited in order to explain dispositional behaviour. Chapter 1 outlines this distinction in more detail. Chapter 2 offers a summary of the issues surrounding analysis of dispositions and various strategies in contemporary literature to address them, including one of our own. Chapter 3 describes some of the important questions facing the metaphysics of powers including why they're (...) worth positing, and how they might metaphysically explain laws of nature and modality.

Subpart B of 45 Code of Federal Regulations Part 46 (CFR) identifies the criteria according to which research involving pregnant women, human fetuses, and neonates can be conducted ethically in the United States. As such, pregnant women and fetuses fall into a category requiring “additional protections,” often referred to as “vulnerable populations.” The CFR does not define vulnerability, but merely gives examples of vulnerable groups by pointing to different categories of potential research subjects needing additional protections. In this paper, I (...) assess critically the role of this categorization of pregnant women involved in research as “vulnerable,” both as separate entities and in combination with the fetuses they carry. In particular, I do three things: (1) demonstrate that pregnant women qua pregnancy are either not “vulnerable” according to any meaningful definition of that term or that such vulnerability is irrelevant to her status as a research participant; (2) argue that while a fetus may be vulnerable in terms of dependency, this categorization does not equate to the vulnerability of the pregnant woman; and (3) suggest that any vulnerability that appends to women is precisely the result of federal regulations and dubious public perceptions about pregnant women. I conclude by demonstrating how this erroneous characterization of pregnant women as “vulnerable” and its associated protections have not only impeded vital research for pregnant women and their fetuses, but have also negatively affected the inclusion of all women in clinical research.

The resultant theory provides an alternative philosophical perspective on the transfinite, but has limited impact on everyday (...) mathematical practice. (shrink)

Corballis suggests that fully vocal communication was invented by modern humans between 170,000 and 50,000 years ago. Because this new form of communication did not require hand gestures, he wondered whether this may have facilitated the development of lithic manufacture. I cast doubt on this interesting notion but offer an enhanced version that may have more potential.
