The binary divide between traditional cognitivist and enactivist paradigms is tied to their respective commitments to understanding cognition as based on knowing that as opposed to knowing how. Using O’Regan’s and No¨e’s landmark sensorimotor contingency theory of perceptual experience as a foil, I demonstrate how easy it is to fall into conservative thinking. Although their account is advertised as decidedly ‘skill-based’, on close inspection it shows itself to be riddled with suppositions threatening to reduce it to a rules-and-representations approach. To (...) remain properly enactivist it must be purged of such commitments and indeed all commitment to mediating knowledge: it must embrace a more radical enactivism. (shrink)

Natural kind essentialism is a specification of the intuitive idea that there are some mind-independent or objective categories in nature. These categories are thought to be characterised by a shared essence, which may involve intrinsic or extrinsic properties, mechanisms, or causal history. While the ontological basis of natural kinds has its roots in antiquity and especially Aristotle, the contemporary notion of a “natural kind” in philosophical discussion is often traced to William Whewell’s and John Stuart Mill’s work in the 1800s. (...) In its more modern form, natural kind essentialism was popularised in the 1970s mainly by Saul Kripke and Hilary Putnam. Traditionally, natural kind essentialism has been associated with intrinsic and microstructural properties, but contemporary work has made it clear that more refined versions of natural kind essentialism may have to accept extrinsic or relational essences.

Should we descry the nature of the self from thought experiments? Shaun Nichols says ‘maybe,’ but only if we use thought experiments that do not recruit the indexical “I” (non-I-recruiting). His reason is that the psychology of “I” perforce mandates that imagination responds to thought experiments that recruit it (I-recruiting) peculiarly. Here, I consider whether he is correct about non-I-recruiting personal identity thought experiments. I argue positively using the same framework, i.e., considering the underlying psychology.

There appear to be multifunctional artefacts of a type such that none of their functions can be attributed only to some proper part of the artefact. I use two examples of allegedly multifunctional artefacts of this kind in what follows, one due to Lynne Rudder Baker (aspirin) and another of my own (a spork). The two examples are meant to make the same point. I discuss her aspirin example, since its discussion has entered the literature, but without its being dealt (...) with satisfactorily. My example is, I believe, more intuitive than that of aspirin, which Baker introduced in her response to a challenge to her views, and so I will mostly rely on my example of a spork, especially at the end of the paper, to make my case. -/- I argue that in at least those two cases, if the standard arguments for distinguishing between an object and what constitutes it are sound, an argument showing that what we might have taken to be a single multifunctional object is in fact a case of multiple single-function artefacts which collocate. Or almost. There is one further assumption needed for these cases, beyond what the constitution cases require, and I produce reasons for accepting that assumption. (shrink)

Thought experiments that concoct bizarre possible world modalities are standard fare in debates on personal identity. Appealing to intuitions raised by such evocations is often taken to settle differences between conflicting theoretical views that, albeit, have practical implications for ethical controversies of personal identity in health care. Employing thought experiments that way is inadequate, I argue, since personhood is intrinsically linked to constraining facts about the actual world. I defend a moderate modal skepticism according to which intuiting across conceptually incongruent (...) worlds constitutes ‘invalid intuitioninferences’—i.e., carrying over intuitions gathered from facts about possible worlds that are at odds with facts about the actual world, for the purpose of making claims about real-life persons and their identity, leads to conceptual incongruences. Such a methodological fallout precludes accurate, informative judgments about personal identity in the actual world, calling into question the adequacy of thought experimental considerations for potential real world applications in medical ethics.

This thesis investigates the relationship between consciousness and self-consciousness. I consider two broad claims about this relationship: a constitutive claim, according to which all conscious experiences constitutively involve self-consciousness; and a typicalist claim, according to which ordinary conscious experiences contingently involve self-consciousness. Both of these claims call for elucidation of the relevant notions of consciousness and self-consciousness. -/- In the first part of the thesis ('The Myth of Constitutive Self-Consciousness'), I critically examine the constitutive claim. I start by offering an (...) elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish between two concepts of self-consciousness: consciousness of one's experience, and consciousness of oneself (as oneself). Each of these concepts yields a distinct variant of the constitutive claim. In turn, each resulting variant of the constitutive claim can be interpreted in two ways: on a 'minimal' or deflationary reading, they fall within the scope of foundational claims about consciousness, while on a 'strong' or inflationary reading, they point to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary readings of either variant of the constitutive claim are plausible and illuminating, but would ideally be formulated without using a term as polysemous as 'self-consciousness'; by contrast, the inflationary readings of either variant are not adequately supported. -/- In the second part of the thesis ('Self-Consciousness in the Real World'), I focus on the second concept of self-consciousness, or consciousness of oneself as oneself. Drawing upon empirical evidence, I defend a pluralist account of self-consciousness so construed, according to which there are several ways in which one can be conscious of oneself as oneself – through conscious thoughts, bodily experiences and perceptual experiences – that make distinct determinate contributions to one's phenomenology. This pluralist account provides us with the resources to vindicate the typicalist claim according to which consciousness of oneself as oneself – a sense of self – is pervasive in ordinary conscious experiences, as a matter of contingent empirical fact. It also provides us with the resources to assess the possibility that a subject might be conscious without being conscious of herself as herself in any way. (shrink)

This essay examines the difficulties faced by the claim that artworks are simple physical objects (or, in the case of non-visual art forms, simple structures of another sort) and examines alternative proposals regarding their ontological nature.

In this paper, I outline a theory of social kinds. A general theory of social kinds has to set out at least three conditions: existence conditions, persistence conditions, and identity conditions. For the sake of expediency, I focus on the existence and persistence conditions. The paper is organized just as life: first with existence, then persistence. I argue that anti-realism is more attractive than realism as an account of the existence conditions, despite the fact that realism has been under-appreciated. Then (...) I argue for a particular theory of the persistence conditions, which I call the basic overlapping traits theory (BOTT), based on an analogy to an approach to personal identity. The upshot of the argument is that from an anti-realist metaphysics we have the capacity to discuss a wider diversity of social phenomena. (shrink)

In debates about the metaphysics of material objects examples of colocated objects are commonly taken to be examples of coincidence too. But the argument that colocation is best understood as involving coincidence is never spelled out. This paper shows under what conditions colocation entails coincidence and argues that the entailment depends on a principle that actually rules out certain forms of colocation. This undermines the argument from colocation to coincidence.

According to some philosophers, if moral agency is understood in behaviourist terms, robots could become moral agents that are as good as or even better than humans. Given the behaviourist conception, it is natural to think that there is no interesting moral difference between robots and humans in terms of moral agency (call it the _equivalence thesis_). However, such moral differences exist: based on Strawson’s account of participant reactive attitude and Scanlon’s relational account of blame, I argue that a distinct (...) kind of reason available to humans—call it _human-relative reason_—is not available to robots. The difference in moral reason entails that sometimes an action is morally permissible for humans, but not for robots. Therefore, when developing moral robots, we cannot consider only what humans can or cannot do. I use examples of paternalism to illustrate my argument. (shrink)

Emergence is typically discussed in the context of mental properties or the properties of the natural sciences, and accounts of emergence within these contexts tend to look a certain way. The emergent property is taken to emerge instantaneously out of, or to be proximately caused by, complex interaction of colocated entities. Here, however, I focus on the properties instantiated by the elements of certain systems discussed in social ontology, such as being a five-dollar bill or a pawn-movement, and I suggest (...) that these properties emerge in a distinctive way. They emerge in part because of a system that is far beyond and typically before the object that instantiates them. I characterize how emergence occurs in these cases, juxtaposing it with how emergence is typically discussed. I then consider whether their emergence is best framed as weak or strong as these notions are characterized in the literature, and I reveal what debates are central to answering this question. Though I will not resolve these debates, I do show a collection of views that would vindicate these properties as strongly emergent and downwardly causing. (shrink)

This paper investigates the notion of ‘distributed cognition’—the idea that entities external to one’s organic brain participate in one’s overall cognitive functioning—and the challenges it poses to the notion of personhood. Related to this is also a consideration of the ever-increasing ways in which neuroprostheses replace and functionally replicate organic parts of the brain. However, the literature surrounding such issues has tended to take an almost exclusively physicalist approach. The common assumption is that, given that non-physicalist theories (chiefly, dualism, and (...) hylomorphism) postulate some form of immaterial ‘soul’, then they are immune from the challenges that these advances in cognitive science pose. The first aim of this paper, therefore, is to argue that this is not the case. The second aim of this paper is to attempt to elucidate a route available for the non-physicalists that will allow them to accept the notion of distributed cognition. By appealing to an Aristotelian framework, I propose that the non-physicalist can accept the notion of distributed cognition by appealing to the notion of ‘unitary life’ which I introduce, as well as to Aristotle’s dichotomy between active and passive mind.

In this article, we develop and defend a new argument for animalism -- the thesis that we human persons are human animals. The argument takes this rough form: since our pets are animals, we are too. We’ll begin with remarks on animalism and its rivals, develop our main argument, and then defend it against a few replies.

Here is a question as intriguing as it is brief: what are we? The animalist’s answer is equal in brevity: we are animals. This stark formulation of the animalist slogan distances it from nearby claims—that we are essentially animals, for example, or that we have purely biological criteria of identity over time. Is the animalist slogan—unburdened by modal or criterial commitments—still interesting, though? Or has it lost its bite? In this article we address such questions by presenting a positive case (...) for the importance of animalism and applying that case to recent critiques. (shrink)

The animalist says we are animals. This thesis is commonly understood as the universal generalization that all human persons are human animals. This article proposes an alternative: the thesis is a generic that admits of exceptions. We defend the resulting view, which we call ‘generic animalism’, and show its aptitude for diagnosing the limits of eight case-based objections to animalism.

This chapter considers potential applications of grounding to the formulation of physicalism. I begin with an overview of competing conceptions of the physical and of physicalism. I then consider whether grounding physicalism overcomes well-known and seemingly fatal problems with supervenience physicalism. I conclude that while grounding physicalism improves upon supervenience physicalism in certain respects, it arguably falls victim to some of the same difficulties.

The subject of this paper is the epistemology of identity: a general theory of knowledge, evidence and justification for the claim that one thing is identical to another. Although identity figures significantly in our epistemic lives, this is a topic that, to the best of my knowledge, has gone entirely unexplored. Initial attempts to integrate such an epistemology into existing theories of evidence---many of which are tailor-made for contingent propositions---are confounded by the necessity of identity. I defend a restricted form (...) of skepticism according to which the only knowable identity claims are trivial. (shrink)

Nel nostro universo, qualunque cosa, dalla più piccola particella alla più smisurata galassia, esiste in un qualche tempo e in un qualche luogo. Ma cosa significa esistere in un qualche tempo? Il fenomeno dell’esistenza temporale gioca un ruolo fondamentale nella comprensione dell’universo e di noi stessi quali creature temporali. Eppure è un fenomeno profondamente misterioso. L’esistenza temporale è da intendersi come una relazione? Che legami ha con l’esistenza dell’ontologia? L’esistenza temporale e la localizzazione spaziale sono due fenomeni essenzialmente differenti o (...) due istanze di un’unica relazione? Tutto ciò che esiste nel tempo esiste nel tempo nello stesso modo? Tutto ciò che è nel tempo è anche nello spazio? (shrink)

Many ordinary things are made up of material things. For example, the statue of Ferdousi in the University of Tehran is made up of a particular piece of bronze. Calling the relation between the statue of Ferdousi and that piece of bronze material constitution, many philosophers have claimed that this relation between a material thing and the thing that it constitutes is identity. Baker, in contrast, believes that these things have genuine unity without necessary identity. In this article, I first (...) illustrate the principles of Baker’s theory and his explanation of this relation. Then I will assess the theory against objections. I will conclude that this theory can successfully explain relation between many of material things, but concerning things belonging to human beings, the theory fails to introduce a criterion for constitution.

Self-consciousness can be understood as the ability to think I-thou-ghts which can be described as thoughts about oneself ‘as oneself’. Self-consciousness possesses two specific correlated features: the first regards the fact that it is grounded on a first-person perspective, whereas the second concerns the fact that it should be considered a consciousness of the self as subject rather than a consciousness of the self as object. The aim of this paper is to analyse a few considerations about Descartes and Hume’s (...) approaches to self-consciousness, as both philosophers introduce a first-personal method of accessing the subjective dimension through an introspective account. Descartes’s view on self-consciousness seems incapable of conceiving and recognizing herself as herself, while Hume’s seems to lack those features assigned to the consciousness of self-as-subject. (shrink)

Subjectivity is that feature of consciousness whereby there is something it is like for a subject to undergo an experience. One persistent challenge in the study of consciousness is to explain how subjectivity relates to, or arises from, purely physical brain processes. But, in order to address this challenge, it seems we must have a clear explanation of what subjectivity is in the first place. This has proven challenging in its own right. For the nature of subjectivity itself seems to (...) resist straightforward characterization. In this paper, I won't address how subjectivity relates to the physical. Instead, I'll address subjectivity itself. I'll do this by introducing and defending a model of subjectivity based on self-acquaintance. My model does not purport to reduce, eliminate, or naturalize subjectivity, but it does make subjectivity more tractable, less paradoxical, and perhaps less dubious to those averse to obscurity.

Viele Menschen halten Patientenverfügungen für ein geeignetes Mittel, um selbstbestimmt zu entscheiden, wie mit ihnen im Fall schwerer Demenz umgegangen werden soll. Die meisten Bioethiker stimmen ihnen zu: Demenzverfügungen seien Ausdruck der „verlängerten Autonomie“ der Patientin. Doch ob sie recht haben, ist unklar. Dem viel beachteten Identitätseinwand zufolge sind die Ausstellerin der Verfügung und ihre schwer demente Nachfolgerin numerisch verschieden: Sie sind zwei und nicht eins. Wenn das stimmt, kann die Ausstellerin nicht verfügen, wie mit ihr im Falle schwerer Demenz (...) umgegangen werden soll. Die Demenzverfügung ist ungültig. In meinem Aufsatz möchte ich eine neue Replik auf diesen Einwand vorstellen. Ihr Ansatzpunkt ist der menschliche Organismus, den wir sehen, wenn wir in den Spiegel blicken. Er kann schwer dement werden, und auch er hat die Patientenverfügung unterschrieben. Warum sollte sie dann ungültig sein? Auf den ersten Blick hat diese Replik eine Reihe von Vorzügen. Insbesondere akzeptiert sie die populären Annahmen, auf denen der Identitätseinwand basiert. Bei näherem Hinsehen zeigen sich jedoch Probleme, die so gravierend sind, dass wir von ihr Abstand nehmen sollten. (shrink)

The article aims at clarifying the viewpoint of a critical realist relational sociology when dealing with the notion of ‘relational subject’. The term ‘relational subject’, as developed by Donati and Archer, The Relational Subject, indicates individual and social subjects as ‘relationally constituted’, i.e. in as much as they acquire qualities and powers through their internal and external social relations. The validity of the relational perspective can be seen on different levels in social ‘collective’ subjects: on the micro level, on the (...) meso level and on the macro level. (shrink)

Mereological nihilism is the view that no objects have proper parts. Despite how counter‐intuitive it is, it is taken quite seriously, largely because it solves a number of puzzles in the metaphysics of material objects – or so its proponents claim. In this article, I show that for every puzzle that mereological nihilism solves, there is a similar puzzle that (a) it doesn’t solve, and (b) every other solution to the original puzzle does solve. Since the solutions to the new (...) puzzles apply just as well to the old puzzles, the old puzzles provide no motivation to be a mereological nihilist. (shrink)

Constitution theorists have argued that due to a difference in persistence conditions, persons are not identical with the animals or the bodies that constitute them. A popular line of objection to the view that persons are not identical with the animals/bodies that constitute them is that the view commits one to undesirable overpopulation, with too many minds and too many thinkers. Constitution theorists are well aware of these overpopulation concerns and have gone a long way toward answering them. However, there (...) is one mental excess worry that remains especially problematic. It is argued here that the worry about too many thoughts, or too many instantiations of mentality in general, remains a serious threat to the constitution view of persons. What exactly the threat is and how it arises is described in detail in Section III. It is then shown that attempts to allay the concern are unsuccessful. I argue, in particular, that appealing to the distinction between derivative and non-derivative instantiation fails to solve the problem. (shrink)

This paper presents a systematic approach for analyzing and explaining the nature of social groups. I argue against prominent views that attempt to unify all social groups or to divide them into simple typologies. Instead I argue that social groups are enormously diverse, but show how we can investigate their natures nonetheless. I analyze social groups from a bottom-up perspective, constructing profiles of the metaphysical features of groups of specific kinds. We can characterize any given kind of social group with (...) four complementary profiles: its “construction” profile, its “extra essentials” profile, its “anchor” profile, and its “accident” profile. Together these provide a framework for understanding the nature of groups, help classify and categorize groups, and shed light on group agency. (shrink)

Moderate holists like French, Copp :369–388, 2007), Hess, Isaacs and List and Pettit argue that certain collectives qualify as moral agents in their own right, often pointing to the corporation as an example of a collective likely to qualify. A common objection is that corporations cannot qualify as moral agents because they lack free will. The concern is that corporations are effectively puppets, dancing on strings controlled by external forces. The article begins by briefly presenting a novel account of corporate (...) moral agency and then demonstrates that, on this account, qualifying corporations do possess free will. Such entities possess and act from their own “actional springs”, in Haji’s :292–308, 2006) phrase, and from their own reasons-responsive mechanisms. When they do so, they act freely and are morally responsible for what they do. (shrink)

. The extended‐mind thesis is the claim that mentality need not be situated just in the brain, or even within the boundaries of the skin. Some versions take “extended selves” be to relatively transitory couplings of biological organisms and external resources. First, I show how EM can be seen as an extension of traditional views of mind. Then, after voicing a couple of qualms about EM, I reject EM in favor of a more modest hypothesis that recognizes enduring subjects of (...) experience and agents with integrated bodies. Nonetheless, my modest hypothesis allows subpersonal states to have nonbiological parts that play essential roles in cognitive processing. I present empirical warrant for this modest hypothesis and show how it leaves room for science and religion to coexist. (shrink)

Big Data has the potential to enable unprecedentedly rigorous quantitative modeling of complex human social relationships and social structures. When such models are extended to nonhuman domains, they can undermine anthropocentric assumptions about the extent to which these relationships and structures are specifically human. Discoveries of relevant commonalities with nonhumans may not make us less human, but they promise to challenge fundamental views of what it is to be human.

Mereological nihilists hold that composition never occurs, so that nothing is ever a proper part of anything else. Substance dualists generally hold that we are each identical with an immaterial soul. In this paper, I argue that every popular objection to substance dualism has a parallel objection to composition. This thesis has some interesting implications. First, many of those who reject composition, but accept substance dualism, or who reject substance dualism and accept composition, have some explaining to do. Secondly, one (...) popular objection to mereological nihilism, one which contends that mereological nihilism is objectionable insofar as it is incompatible with the existence of people, is untenable.

Animalism is at once a bold metaphysical theory and a pedestrian biological observation. For according to animalists, human persons are organisms; we are members of a certain biological species. In this article, I introduce some heretofore unnoticed data concerning the interlocking interests of human persons and human organisms. I then show that the data support animalism. The result is a novel and powerful argument for animalism. Bold or pedestrian, animalism is true.

In this paper, I examine the claim that self-consciousness is highly morally significant, such that the fact that an entity is self-conscious generates strong moral reasons against harming or killing that entity. This claim is apparently very intuitive, but I argue it is false. I consider two ways to defend this claim: one indirect, the other direct. The best-known arguments relevant to self-consciousness's significance take the indirect route. I examine them and argue that in various ways they depend on unwarranted (...) assumptions about self-consciousness's functional significance, and once these assumptions are undermined, motivation for these arguments dissipates. I then consider the direct route to self-consciousness's significance, which depends on claims that self-consciousness has intrinsic value or final value. I argue what intrinsic or final value self-consciousness possesses is not enough to generate strong moral reasons against harming or killing. (shrink)

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

Rose and Schaffer (forthcoming) argue that teleological thinking has a substantial influence on folk intuitions about composition. They take this to show (i) that we should not rely on folk intuitions about composition and (ii) that we therefore should not reject theories of composition on the basis of intuitions about composition. We cast doubt on the teleological interpretation of folk judgments about composition; we show how their debunking argument can be resisted, even on the assumption that folk intuitions have a (...) teleological source; and we argue that, even if folk intuitions about composition carry no weight, theories of composition can still be rejected on the basis of the intuitions of metaphysicians.

According to the doctrine of animalism, we are animals in the primary and non-derivative sense. In this article, I introduce and defend a novel argument for the view.

When some objects are the parts of another object, they compose that object and that object is composite. This article is intended as an introduction to the central questions about composition and a highly selective overview of various answers to those questions. In §1, we review some formal features of parthood that are important for understanding the nature of composition. In §2, we consider some answers to the question: which pluralities of objects together compose something? As we will see, the (...) dominant answers are all of them and none of them. In §§3-4, we examine one of the main arguments that has driven philosophers to these extreme answers: the argument from vagueness. In §5, we turn to the question of whether composition is unique: is it sometimes the case that some things compose more than one thing? Finally, in §6, we turn from the question of which composites exist to the question of which composites exist fundamentally. (shrink)

Recently, a number of people have argued that certain entities embodied by groups of agents themselves qualify as agents, with their own beliefs, desires, and intentions; even, some claim, as moral agents. However, others have independently argued that fully-fledged moral agency involves a capacity for reactive attitudes such as guilt and indignation, and these capacities might seem beyond the ken of “collective” or “ corporate ” agents. Individuals embodying such agents can of course be ashamed, proud, or indignant about what (...) the agent has done. But just as an entity needs to have its own beliefs, desires, and intentions to qualify as a bona fide agent, the required capacity for reactive attitudes is a capacity to have one’s own reactive attitudes. If fully-fledged moral agency requires reactive attitudes, the corporate agent must itself be capable of guilt and indignation. In this paper, we argue that at least certain corporate agents are. Or, more precisely, we argue that if there are bona fide corporate agents, these agents can have the capacities that are both associated with guilt and indignation and plausibly required for moral agency; in particular certain epistemic and motivational capacities.

Among your closest associates is a certain human animal – a living, breathing, organism. You see it when you look in the mirror. When it is sick, you don't feel too well. Where it goes, you go. And, one thinks, where you go, it must follow. Indeed, you can make it move through sheer force of will. You bear, in short, an important and intimate relation to this, your animal. So too rest of us with our animals. Animalism says that (...) this relation is nothing short of identity. According to animalists, we do not only coincide with or constitute or inhabit or otherwise hang out with these close associates, our animals: we are them. In this article, I offer an opinionated take on what animalism might be and situate it against contemporary rivals. Then, I outline a simple case for animalism. Finally, I sketch non-standard routes for animalists to take in light of standard challenges. My goal in all of this is to open up some new avenues of animalist thinking. (shrink)

I agree with a great deal in Helen Steward's paper. I am especially sympathetic to her suggestion that we gain metaphysical illumination by considering various ways in which we arrive at ideas of certain kinds of individuals by abstraction from those of more basic kinds. My aim is to pursue that suggestion by exploring the proposal that a grounding node in this form of abstraction may be characterized by Exclusivity in spatial location. Steward claims that we arrive at our ideas (...) of specific events and processes by different modes of abstraction in cases where a more basic persisting individual undergoes some kind of change. I argue that the most basic individuals in this hierarchy of abstraction are enduring substances that occupy their spatial location exclusively at all times: no two such substances are ever precisely collocated.

This paper argues for including stuff in one's ontology. The distinction between things and stuff is first clarified, and then three different ontologies of the physical universe are spelled out: a pure thing ontology, a pure stuff ontology, and a mixed ontology of both things and stuff. Eleven different reasons for including stuff in one's ontology are given. Then five objections to positing stuff are considered and rejected.

This paper sketches and motivates a metaphysics of mind that is both substance dualist and, to a large extent, property reductive. Call it “property reductive emergent dualism”. Section “Emergent Dualism” gives the broad outlines of the view. Sections “Problems of Mental Causation” and “Theoretical Virtues” argue that it can claim several advantages over non-reductive physicalist theories of mind. Section “Problems of Mental Causation” considers metaphysical challenges to mental causation in detail. Section “Theoretical Virtues” considers overall theoretical virtues: ontological and ideological (...) economy, unification with physical sciences, the promise of explanatory gain. On these grounds, I propose that the view coupling substance dualism with property reductivism deserves further philosophical attention. (shrink)

Persons think. Bodies, time-slices of persons, and brains might also think. They have the necessary neural equipment. Thus, there seems to be more than one thinker in your chair. Critics assert that this is too many thinkers and that we should reject ontologies that allow more than one thinker in your chair. I argue that cases of multiple thinkers are innocuous and that there is not too much thinking. Rather, the thinking shared between, for example, persons and their bodies is (...) exactly what we should expect at the intersection of part sharing and the supervenience of the mental on the physical. I end by responding to the overcrowding objection, the personhood objection, the personal-pronoun reference problem and the epistemic objection. (shrink)

The neuroscience revolution has led many scientists to posit “expansive” or “thinking” brains that instantiate rich psychological properties. As a result, some scientists now even claim you are identical to such a brain. However, Eric Olson has offered new arguments that thinking brains cannot exist due to their intuitively “abominable” implications. After situating the commitment to thinking brains in the wider scientific discussions in which they are posited, I then critically assess Olson's arguments against such entities. Although highlighting an important (...) insight, I show that Olson's objections to the existence of thinking brains fail and that a wider discussion engaging our new empirical findings is actually required in order to resolve the deeper issues.
