We investigate the interactions of formula complexity in weak set theories with the axioms available there. In particular, we show that swapping bounded and unbounded quantification preserves formula complexity in presence of the axiom of foundation weakened to an arbitrary set base, while it does not if the axiom of foundation is further weakened to a proper class base. More attention is being paid to the necessary axioms employed in the positive results, than to the combinatorial strength of the positive (...) results themselves. (shrink)

Philosophical tradition and conspiracy theorists converge in suggesting that ordinary people ought to do their own research, rather than accept the word of others. In this paper, I argue that it’s no accident that conspiracy theorists value lay research on expert topics: such research is likely to undermine knowledge, via its effects on truth and justification. Accepting expert testimony is a far more reliable route to truth. Nevertheless, lay research has a range of benefits; in particular, it is likely to (...) lead to greater understanding, even when it does not lead to knowledge. I argue that we can reap most of the genuine benefits of lay research while minimizing the risks by engaging in exploratory, rather than truth-directed, inquiry. To engage in exploratory inquiry is to engage dogmatically, expecting to be unable to confirm the expert view or to disconfirm rivals. (shrink)

No-platforming—the refusal to allow those who espouse views seen as inflammatory the opportunity to speak in certain forums—is very controversial. Proponents typically cite the possibility of harms to disadvantaged groups and, sometimes, epistemically paternalistic considerations. Opponents invoke the value of free speech and respect for intellectual autonomy in favor of more open speech, arguing that the harms that might arise from bad speech are best addressed by rebuttal, not silencing. In this article, I argue that there is a powerful consideration (...) in favor of no-platforming some speakers: allowing them a platform generates genuine higher-order evidence in favor of their claims. When that higher-order evidence would be misleading, we may reasonably believe it should not be generated. (shrink)

Why do people endorse conspiracy theories? There is no single explanation: different people have different attitudes to the theories they say they believe. In this paper, I argue that for many, conspiracy theories are serious play. They’re attracted to conspiracy theories because these theories are engaging: it’s fun to entertain them (witness the enormous number of conspiracy narratives in film and TV). Just as the person who watches a conspiratorial film suspends disbelief for its duration, so many conspiracy theorists do (...) not believe the theories they endorse; rather, they suspend disbelief in them. I argue that the serious play hypothesis explains some characteristic features of conspiracy theories, such as their gamification and the kind of relationship they have to evidence. (shrink)

We are constantly called upon to evaluate the evidential weight of testimony, and to balance its deliverances against our own independent thinking. ‘Intellectual autonomy’ is the virtue that is supposed to be displayed by those who engage in cognition in this domain well. I argue that this is at best a misleading label for the virtue, because virtuous cognition in this domain consists in thinking with others, and intelligently responding to testimony. I argue that the existing label supports an excessively (...) individualistic conception of good thinking, both within and outside philosophy. I propose replacing ‘intellectual autonomy’ with ‘intellectual interdependence’, which properly emphasises the depth of our reliance on one another, without suggesting we ought ever to be epistemically servile. (shrink)

Consciousness, or its lack, is often invoked in debates in applied and normative ethics. Conscious beings are typically held to be significantly more morally valuable than non-consious, so that establishing whether a being is conscious becomes of critical importance. In this paper, I argue that the supposition that phenomenal consciousness explains the value of our experiences or our lives, and the moral value of beings who are conscious, is less well-grounded than is commonly thought. A great deal of what matters (...) to us and about us can be explained by functional and representational properties that may not be sufficient for phenomenal consciousness. I conclude with some reflections on how these claims might affect debates in ethics. (shrink)

An influential model holds that obsessive–compulsive disorder is caused by distinctive personality traits and belief biases. But a substantial number of sufferers do not manifest these traits. I propose a predictive coding account of the disorder, which explains both the symptoms and the cognitive traits. On this account, OCD centrally involves heightened and dysfunctionally focused attention to normally unattended sensory and motor representations. As these representations have contents that predict catastrophic outcomes, patients are disposed to engage in behaviors and mental (...) rituals designed to forestall these outcomes or to produce more precise information. The same representations also cause the cognitive traits characteristic of sufferers. (shrink)

It’s widely held that a lack of intellectual humility is part of the reason why flagrantly unjustified beliefs proliferate. In this paper, I argue that an excess of humility also plays a role in allowing for the spread of misinformation. Citing experimental evidence, I show that inducing intellectual humility causes people inappropriately to lower their confidence in beliefs that are actually justified for them. In these cases, they manifest epistemic humility in ways that make them epistemically worse off. I argue (...) that epistemic humility may fail to promote better beliefs because it functions for us against the background of our individualistic theory of responsible epistemic agency: until we reject such theories, intellectual humility is as much a problem as a solution to epistemic ills. Virtue epistemology is inadequate as a response to unjustified beliefs if it does not look beyond the virtues to our background beliefs. (shrink)

There's heated debate around whether people who did terrible things in the past, at a time when there was widespread acceptance of such actions, are appropriately blamed by us, on the grounds they weren't really morally ignorant, or their ignorance was itself culpable. I point to puzzles that arise if we blame them. We need to explain how they could act so badly if they weren't fully ignorant. I argue that plausible answers to that question entail that they're not blameworthy, (...) or that we lack standing to blame them. (shrink)

Recently, various philosophers have argued that we can obtain knowledge via the imagination. In particular, it has been suggested that we can come to know concrete, empirical matters of everyday significance by appropriately imagining relevant scenarios. Arguments for this thesis come in two main varieties: black box reliability arguments and constraints-based arguments. We suggest that both strategies are unsuccessful. Against black-box arguments, we point to evidence from empirical psychology, question a central case-study, and raise concerns about a (claimed) evolutionary rationale (...) for the imagination's reliability. Against the constraints-based account, we argue that to the extent that it works, this does not give rise to knowledge that is distinctively from the imagination. We conclude by suggesting that the imagination's role in raising possibilities, traditionally seen as part of the context of discovery, can in fact play a role in justification, including as a bulwark against certain sorts of skepticism.

Visual cortical prostheses (VCPs) have the potential to provide artificial vision for visually impaired persons. However, the nature and utility of this form of vision is not yet fully understood. Participants in the early feasibility trial for the Orion VCP were interviewed to gain insight into their experiences using artificial vision, their motivations for participation, as well as their expectations and assessments of risks and benefits. Analyzed using principles of grounded theory and an interpretive description approach, these interviews yielded six (...) themes, including: the irreducibility of benefit to device functionality, mixed expectations for short-term device functionality and long-term technological advancement of visual prostheses, and a broad range of risks, concerns, and fears related to trial participation. We argue that these narratives motivate a nuanced set of ethical considerations related to the complex relationship between functionality and benefit, the intersection of user experience with disability justice, and the import of expectations and indirect risks on consent.

The aim of this article is to argue, by example, for neuroethics as a new way of doing ethics. Rather than simply giving us a new subject matter—the ethical issues arising from neuroscience—to attend to, neuroethics offers us the opportunity to refine the tools we use. Ethicists often need to appeal to the intuitions provoked by consideration of cases to evaluate the permissibility of types of actions; data from the sciences of the mind give us reason to believe that some (...) of these intuitions are less reliable than others. I focus on the doctrine of double effect to illustrate my case, arguing that experimental results suggest that appeal to it might be question-begging. The doctrine of double effect is supposed to show that there is a moral difference between effects that are brought about intentionally and those that are merely foreseen; I argue that the data suggest that we regard some effects as merely foreseen only because we regard bringing them about as permissible. Appeal to the doctrine of double effect therefore cannot establish that there are such moral differences. (shrink)

Several ethicists have argued that research trials and treatment programs that involve the provision of drugs to addicts are prima facie unethical, because addicts can’t refuse the offer of drugs and therefore can’t give informed consent to participation. In response, several people have pointed out that addiction does not cause a compulsion to use drugs. However, since we know that addiction impairs autonomy, this response is inadequate. In this paper, I advance a stronger defense of the capacity of addicts to (...) participate in the programs envisaged. I argue that it is only in certain circumstances that addicts find themselves choosing in ways that conflict with their genuine preferences. Research and treatment programs have none of the features that characterize choices in these autonomy-undermining circumstances, and there is therefore no reason to think that addicts lack the capacity to give informed consent to these programs.

This book looks at the role of the imagination in science, from both philosophical and psychological perspectives. These contributions combine to provide a comprehensive and exciting picture of this under-explored subject.

Many biological investigations are organized around a small group of species, often referred to as ‘model organisms’, such as the fruit fly Drosophila melanogaster. The terms ‘model’ and ‘modelling’ also occur in biology in association with mathematical and mechanistic theorizing, as in the Lotka–Volterra model of predator-prey dynamics. What is the relation between theoretical models and model organisms? Are these models in the same sense? We offer an account on which the two practices are shown to have different epistemic characters. (...) Theoretical modelling is grounded in explicit and known analogies between model and target. By contrast, inferences from model organisms are empirical extrapolations. Often such extrapolation is based on shared ancestry, sometimes in conjunction with other empirical information. One implication is that such inferences are unique to biology, whereas theoretical models are common across many disciplines. We close by discussing the diversity of uses to which model organisms are put, suggesting how these relate to our overall account. 1 Introduction2 Volterra and Theoretical Modelling3 Drosophila as a Model Organism4 Generalizing from Work on Model Organisms5 Phylogenetic Inference and Model Organisms6 Further Roles of Model Organisms6.1 Preparative experimentation6.2 Model organisms as paradigms6.3 Model organisms as theoretical models6.4 Inspiration for engineers6.5 Anchoring a research community7 Conclusion.

The author comments on the article “The Neurobiology of Addiction: Implications for Voluntary Control of Behavior,‘ by S. E. Hyman. Hyman’s article suggests that addicted individuals have impairments in cognitive control of behavior. The author agrees with Hyman’s view that addiction weakens the addict’s ability to align his actions with his judgments. The author states that neuroethics may focus on brains and highlight key aspects of behavior but we still risk missing explanatory elements. Accession Number: 24077912; Authors: Levy, Neil 1,2; (...)

Although the literature on social innovation has focused primarily on social enterprises, social innovation has long occurred within mainstream corporations. Drawing upon recent scholarship on social movements and institutional complexity, we analyze how movements foster corporate social innovation (CSI). Our context is the adoption of green information systems (“green IS”), which are information systems employed to transform organizations and society into more sustainable entities. We trace the historical emergence of green IS as a corporate response to increasing demands for sustainability (...) reporting, a key social innovation that environmental activists helped to create. Drawing upon extensive survey data from more than 400 U.S. firms, we then examine how managers perceived environmental activism in relation to broader field pressures for change and how their perceptions of both were related to green IS adoption. The results reveal that activists were more effective at influencing adoption indirectly by transforming organizational fields than by directly influencing corporate managers. Combined with the historical analysis, these findings suggest that CSI emerged out of ongoing interactions between activists, corporate managers, and other influential actors within a broader social innovation system. Activists helped to create conditions for social innovation, but corporations took the lead in developing new practices. (shrink)

Ce troisième numéro des Cahiers de philosophie de Paris XII Val-de-Marne comporte deux parties bien distinctes qui correspondent aux activités du Centre de recherches sur la philosophie hellénistique et romaine que dirige Carlos Lévy et du Centre d'études phénoménologiques que dirige Françoise Dastur. La partie antique est consacrée à la philosophie hellénistique (épicurisme et scepticisme néopyrrhonien) ainsi qu'au moyen et néo-platonisme. L'association de ces périodes que l'histoire de la philosophie ancienne a trop tendance à étudier séparément permet une perception diachronique (...) qui met mieux en valeur les éléments de continuité et les différences entre ces textes. La partie phénoménologique rassemble les actes d'un séminaire et d'un colloque auquel ont collaboré de nombreux chercheurs. Elle atteste avec éclat la très grande vigueur et l'extraordinaire diversité des recherches actuelles dans ce domaine, en France comme dans la plupart des pays européens. (shrink)

This book brings cutting edge neuroscience and psychology into dialogue with philosophical reflection to illuminate the loss of control experienced by addicts, and thereby cast light on ordinary agency and the way in which it sometimes goes wrong.

ABSTRACT In A Metaphysics for Freedom and related papers, Helen Steward advances a new argument for incompatibilism. Though she concedes that the luck objection is persuasive with regard to existing versions of libertarianism, she claims that agency itself is incompatible with determinism: we are only agents at all if we are able to settle matters concerning our movements, where settling something requires that prior to our settling it lacked sufficient conditions. She argues that genuine agents settle very fine-grained aspects of (...) their movements: when and how they move, even when and how their neurons fire. In this paper, I advance two linked arguments against agency incompatibilism. I argue, first, that we do not exercise direct control over the fine-grained aspects of our movements. Rather, we control these movements indirectly, by intentionally engaging in broadly individuated action types. Second, I argue that these aspects of our movements are lucky for us and, since this is true, they cannot play the role of grounding our agency. (shrink)

The claim that addiction is a brain disease is almost universally accepted among scientists who work on addiction. The claim’s attraction rests on two grounds: the fact that addiction seems to be characterized by dysfunction in specific neural pathways and the fact that the claim seems to the compassionate response to people who are suffering. I argue that neural dysfunction is not sufficient for disease: something is a brain disease only when neural dysfunction is sufficient for impairment. I claim that (...) the neural dysfunction that is characteristic of addiction is not sufficient for impairment, because people who suffer from that dysfunction are impaired, sufficiently to count as diseased, only given certain features of their context. Hence addiction is not a brain disease (though it is often a disease, and it may always involve brain dysfunction). I argue that accepting that addiction is not a brain disease does not entail a moralizing attitude toward people who suffer as a result of addiction; if anything, it allows for a more compassionate, and more effective, response to addiction.

Mental acts are conspicuously absent from philosophical debates over the nature of action. A typical protagonist of a typical scenario is far more likely to raise her arm or open the window than she is to perform a calculation in her head or talk to herself silently. One possible explanation for this omission is that the standard ‘causalist’ account of action, on which acts are analyzed in terms of mental states causing bodily movements, faces difficulties in accommodating some paradigmatic cases (...) of mental action – or so I argue. After drawing out these objections to causalism, I outline a more promising approach. Building on previous work, I show how the approach I favour, on which the attempt to analyze action is dispensed with, provides a unified account of both mental and physical action. (shrink)

The paper proposes a novel solution to the problem of the time of a killing (ToK), which persistently besets theories of act-individuation. The solution proposed claims to expose a crucial wrong-headed assumption in the debate, according to which ToK is essentially a problem of locating some event that corresponds to the killing. The alternative proposal put forward here turns on recognizing a separate category of dynamic occurents, viz. processes. The paper does not aim to mount a comprehensive defense of process (...) ontology, relying instead on extant defenses. The primary aim is rather to put process ontology to work in diagnosing the current state of play over ToK, and indeed in solving it. (shrink)

This brief paper sketches the main theses of my recent book Bad Beliefs. The book defends the view that human cognition is more evidence responsive than most psychologists and naturalistic philosophers think. In particular, we are responsive to the abundant higher-order evidence that we encounter in experiments and in everyday life.

In Minds, Brains, and Law, Michael Pardo and Dennis Patterson argue that current attempts to use neuroscience to inform the theory and practice of law founder because they are built on confused conceptual foundations. Proponents of neurolaw attribute to the brain or to its parts psychological properties that belong only to people; this mistake vitiates many of the claims they make. Once neurolaw is placed on a sounder conceptual footing, Pardo and Patterson claim, we will see that its more dramatic (...) claims are false or meaningless, though it might be able to provide inductive evidence for particular less dramatic claims (that a defendant may be lying, or lacks control over their behavior, for instance). In response, I argue that the central conceptual confusions identified by Pardo and Patterson are not confusions at all. Though some of the claims made by its proponents are hasty and sometimes they are confused, there are no conceptual barriers to attributing psychological properties to brain states. Neuroscience can play a role in producing evidence that is more reliable than subjective report or behavior; it therefore holds out the possibility of dramatically altering our self-conception as agents and thereby the law.

Papers from the 1994 meeting represent a broad review of contemporary experimental work on quantum phenomena, emphasizing state-of-the-art experimental science. Useful as an introductory manual for young researchers, the volume addresses topics that include: experiments with single and ultracold ato.

In this highly original book, Donald Levy considers the most important and persuasive of these philosophical criticisms, as articulated by four figures: Ludwig Wittgenstein, William James, Alasdair MacIntyre, and Adolf Grunbaum.

This paper is a response to Giubilini and Minerva's defence of infanticide. I argue that any account of moral worth or moral rights that depends on the intrinsic properties of individuals alone is committed to agreeing with Giubilini and Minerva that birth cannot by itself make a moral difference to the moral worth of the infant. However, I argue that moral worth need not depend on intrinsic properties alone. It might also depend on relational and social properties. I claim that (...) the in principle availability of neonates to participate in scaffolded interactions with carers might plausibly be seen as contributing to their moral worth. (shrink)

I describe a new problem for metaethical constructivism. The problem arises when agents make conflicting judgments, so that the constructivist is implausibly committed to denying they have any reason for any of the available options. The problem is illustrated primarily with reference to Sharon Street’s version of constructivism. Several possible solutions to the problem are explained and rejected.
