Davidson argues that mental properties are causally relevant properties. I argue that Davidson cannot appeal to ceteris paribus causal laws to ensure that these properties are causally relevant, if he wishes to retain his argument for anomalous monism. Second, I argue that the appeal to supervenience cannot, by itself, give us an account of the causal relevancy of mental properties. I argue that, while mental properties may indeed 'make a difference' to the causally efficacious properties of events, this is not (...) sufficient to show that mental properties are causally relevant.

Kim's exclusion argument threatens to show that irreducible constituted objects are epiphenomenal. Kim's arguments are examined and found to be unconvincing; that a constituted cause requires its constituent to be a cause is not an adequate reason to reject the causation of the constituted object (event or property-instance). However, I introduce and argue for, the Causal Power Uniqueness Condition (CPUC). I argue that CPUC and the causal closure of the physical, implies that constituted objects or property-instances are not novel causal (...) powers. (shrink)

Daniel Dennett has claimed that if Chalmers' argument for the irreducibility of consciousness were to succeed, an analogous argument would establish the truth of Vitalism. Chalmers denies that there is such an analogy. I argue that the analogy does have merit and that skepticism is called for.

David Chalmers claims that the logical possibility of ‘zombie worlds’ — worlds physically indiscernible from the actual world, but that lack consciousness — reveal that consciousness is a distinct fact, or property, in addition to the physical facts or properties.The ‘existence’ or possibility of Zombie worlds violates the physicalist demand that consciousness logically supervene upon the physical. On the assumption that the logical supervenience of consciousness upon the physical is, indeed, a necessary entailment of physicalism, the existence of zombie worlds (...) implies the falsity of physicalism. How do we determine the logical possibility of zombie worlds? By conceptual analysis of the concepts involved, keeping empirical facts in mind. (shrink)

My aim in this thesis is to explain how a non-reductionist metaphysics can accommodate the causal relevance of the psychological and of the special sciences generally. According to physicalism, all behavior is caused by brain-states; given "folk-psychology", behavior is caused by some psychological state. If psychological states are distinct from brain states, then our behavior is overdetermined and this, it is claimed, is unacceptable. I argue that this consequence is not unacceptable. I claim that our explanatory practice should guide our (...) ontological commitment. If we can offer true explanations that appeal to more than one event, then we are committed to overdetermination for the event explained. I argue that accepting overdetermination is not absurd and that we can give an adequate account of causal relevance for psychological and other supervenient properties. The result is a partial defense of both property and event pluralism. Recent work by Davidson, Fodor, Jackson, Kim, Pettit and Yablo receives explicit and critical discussion. (shrink)

Santayana's epiphenomenalism is best understood as part of his thinking about teleology and final causes. Santayana makes a distinction between final causes, which he rejects, and teleology, which he finds ubiquitous. Mental causation is identified with a doctrine of final causes which he argues is an absurd form of causation. Thus mental causes are rejected and Santayana embraces epiphenomenalism.

In most children’s hospitals, there are very few ethics consultations, even though there are many ethically complex cases. We hypothesize that the reason for this may be that hospitals develop different mechanisms to address ethical issues and that many of these mechanisms are closer in spirit to the goals of the pioneers of clinical ethics than is the mechanism of a formal ethics consultation. To show how this is true, we first review the history of collaboration between philosophers and physicians (...) about clinical dilemmas. Then, as a case-study, we describe the different venues that have developed at one children’s hospital to address ethical issues. At our hospital, there are nine different venues in which ethical issues are regularly and explicitly addressed. They are ethics committee meetings, Nursing Ethics Forum, ethics Brown Bag workshops, PICU ethics rounds, Grand Rounds, NICU Comprehensive Care Rounds, Palliative Care Team case conferences, multidisciplinary consults in Fetal Health Center, and ethics consultations. In our hospital, ethics consults account for only a tiny percentage of ethics discussions. We suspect that most hospitals have multiple and varied venues for ethics discussions. We hope this case study will stimulate research in other hospitals analyzing the various ways in which ethicists and ethics committees can build an ethical environment in hospitals. Such research might suggest that ethicists need to develop a different set of “core competencies” than the ones that are needed to do ethics consultations. Instead, they should focus on their skills in creating multiple “moral spaces” in which regular and ongoing discussion of ethical issues would take place. A successful ethicist would empower everyone in the hospital to speak up about the values that they believe are central to respectful, collaborative practice and patient care. Such a role is closer to what the first hospital philosophers set out to do than in the role of the typical hospital ethics consultant today. (shrink)

Historically, laws and policies to criminalize drug use or possession were rooted in explicit racism, and they continue to wreak havoc on certain racialized communities. We are a group of bioethicists, drug experts, legal scholars, criminal justice researchers, sociologists, psychologists, and other allied professionals who have come together in support of a policy proposal that is evidence-based and ethically recommended. We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation. We (...) also call for criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs to be expunged, and for those currently serving time for these offenses to be released. In effect, we call for an end to the “war on drugs.”. (shrink)

We can perceive not only low-level features of events such as color and motion, but also seemingly higher-level properties such as causality. A prototypical example of causal perception is the ”launching effect’: one object moves toward a stationary second object until they are adjacent, at which point A stops and B starts moving in the same direction. Beyond these motions themselves --- and regardless of any higher-level beliefs --- this display induces a vivid visual impression of causality, wherein A is (...) seen to cause B’s motion. Do such percepts reflect a unitary category of visual processing, or might there be multiple distinct forms of causal perception? While launching is often simply equated with causal perception, researchers have sometimes described other phenomena such as ”triggering’ and ”entraining’. We used psychophysical methods to determine whether these labels really carve visual processing at its joints, and how putatively different forms of causal perception relate to each other. Previous research demonstrated retinotopically specific adaptation to causality: exposure to causal launching makes subsequent ambiguous events in that same location more likely to be seen as non-causal ”passing’. Here, after replicating this effect, we show that exposure to triggering also yields retinotopically specific adaptation for subsequent ambiguous launching displays, but that exposure to entraining does not. Collectively, these results reveal that visual processing distinguishes some types of causal interactions. (shrink)

This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called “experimental philosophical bioethics” (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people’s moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute to substantive (...) ethical questions about what should be done in a given context. What are some of the ways in which this aim has been pursued? In this paper, we employ a case study approach to examine and critically evaluate four strategies from the recent literature by which scholars in bioxphi have leveraged empirical data in the service of normative arguments.

I argue that José Luis Bermúdez has not shown that there is a paradox in our concept of self-consciousness. The deflationary theory is not a plausible theory of self-consciousness, so its paradoxicality is irrelevant. A more plausible theory, 'the simple theory', is not paradoxical. However, I do think there is a puzzle about the connection between self-consciousness and 'I'-thoughts.

_Personal Identity and Self-Consciousness_ is about persons and personal identity. What are we? And why does personal identity matter? Brian Garrett, using jargon-free language, addresses questions in the metaphysics of personal identity, questions in value theory, and discusses questions about the first person singular. Brian Garrett makes an important contribution to the philosophy of personal identity and mind, and to epistemology.

Why is there something rather than nothing? Does God exist? Does time flow? What are we? Do we have free will? What is truth? Metaphysics is concerned with ourselves and reality, and the most fundamental questions regarding existence. This clear and accessible introduction covers the central topics in metaphysics in a concise but comprehensive way. Brian Garrett discusses the crucial concepts in a highly readable manner, easing the reader in with a look at some important philosophical problems. He (...) addresses key areas of metaphysics: God Existence Modality Universals and particulars Facts Paradoxes of material constitution Causation Time Free will Personal identity Truth. This second edition has been thoroughly revised. Most chapters include substantial amounts of new material, and there are additional chapters on Existence, Modality, Facts and Paradoxes of Material Constitution. _What is this thing called Metaphysics?_ contains many helpful student-friendly features. Each chapter concludes with a useful summary of the main ideas discussed, a glossary of important terms, study questions, annotated further reading, and a guide to web resources. Text boxes provide bite-sized summaries of key concepts and major philosophers, and clear and interesting examples are used throughout. (shrink)

In “Against Arguments from Reference” (Mallon et al., 2009), Ron Mallon, Edouard Machery, Shaun Nichols, and Stephen Stich (hereafter, MMNS) argue that recent experiments concerning reference undermine various philosophical arguments that presuppose the correctness of the causal-historical theory of reference. We will argue three things in reply. First, the experiments in question—concerning Kripke’s Gödel/Schmidt example—don’t really speak to the dispute between descriptivism and the causal-historical theory; though the two theories are empirically testable, we need to look at quite different data (...) than MMNS do to decide between them. Second, the Gödel/Schmidt example plays a different, and much smaller, role in Kripke’s argument for the causal-historical theory than MMNS assume. Finally, and relatedly, even if Kripke is wrong about the Gödel/Schmidt example—indeed, even if the causal-historical theory is not the correct theory of names for some human languages—that does not, contrary to MMNS’s claim, undermine uses of the causalhistorical theory in philosophical research projects.

In our recent article, together with more than 60 of our colleagues, we outlined a proposal for drug policy reform consisting of four specific yet interrelated strategies: (1) de jure decriminalization of all psychoactive substances currently deemed illicit for personal use or possession (so-called “recreational” drugs), accompanied by harm reduction policies and initiatives akin to the Portugal model; (2) expunging criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs (and releasing those serving (...) time for these offenses), while delivering retroactive ameliorative relief; (3) the ultimate legalization and careful regulation of currently illicit drugs; and (4) the delivery of a new “Marshall Plan” focused on community-building initiatives, expanded harm reduction programs, and social and health care support efforts (Earp et al. 2021). We were gratified to see so many thoughtful commentaries on our proposal, and we respond to them in part in this reply. (shrink)

The question of what makes someone the same person through time and change has long been a preoccupation of philosophers. In recent years, the question of what makes ordinary or lay people judge that someone is—or isn’t—the same person has caught the interest of experimental psychologists. These latter, empirically oriented researchers have sought to understand the cognitive processes and eliciting factors that shape ordinary people’s judgments about personal identity and the self. Still more recently, practitioners within an emerging discipline, experimental (...) philosophical bioethics or “bioxphi”—the focus of this chapter—have adopted a similar aim and employed similar methodologies, but with two distinctive features: (a) a special concern for enhanced ecological validity in the examples and populations studied; and (b) an interest in contributing to substantive normative debates within the wider field of bioethics. Our aim in this chapter is to sample illustrative work on personal identity in bioxphi, explore how it relates to studies in psychology covering similar terrain, and draw out the implications of this work for matters of bioethical concern. In pursuing these issues, we highlight recent work in bioxphi that includes the perceived validity of advance directives following neurodegeneration, the right of psychologically altered study participants to withdraw from research, how drug addiction may cause one to be regarded by others as “a completely different person,” the effect of deep-brain stimulation on perceptions of the self, and the potential influence of moral enhancement interventions on intuitive impressions of a person’s character.

In this paper, I argue that neither the #257 argument nor the #258 argument in Wittgenstein's Philosophical Investigations undermines the coherence of the Cartesian Model, according to which a sensation word, such as `headache' or `tickle', gets its meaning in virtue of an act of `inner' association or ostensive definition. In addition, I argue against the standard assumption that the diarist's language of #258 is logically private.

In this discussion paper, I evaluate some arguments of Mark Johnston's which appear in his articles «Fission and the Facts» and «Reasons and Reductionism» . My primary concern is with his description of fission cases, and his assessment of the implications of such cases for value theory. In particular, Johnston advances the following three claims:Rejecting the intrinsicness of identity is an arbitrary response to the paradox of fission;Fission cases involve indeterminate identity;Contra Parfit, fission cases have no implications for value theory (...) in the actual world.I argue that and are false, and that , if true, is not true for any reason that Johnston gives.

In this discussion note we argue, contrary to the thrust of a recent article by Jenann Ismael, that resolving the paradox of predictability does not require denying the possibility of a natural oracle, and thus stands in no need of the response that she proposes.

This entry summarizes an emerging subdiscipline of both empirical bioethics and experimental philosophy (“x-phi”) which has variously been referred to as experimental philosophical bioethics, experimental bioethics, or simply “bioxphi”. Like empirical bioethics, bioxphi uses data-driven research methods to capture what various stakeholders think (feel, judge, etc.) about moral issues of relevance to bioethics. However, like its other parent discipline of x-phi, bioxphi tends to favor experiment-based designs drawn from the cognitive sciences – including psychology, neuroscience, and behavioral economics – to (...) tease out why and how stakeholders think as they do.
