This paper aims at bringing together two debates in metaphysics that so far have been kept separate: the debate about determinism vs. indeterminism as de re modality on the one hand, and the debate about persistence on the other hand. Both debates significantly involve talk of things. We will show that working out a proper semantics for singular terms and an accompanying theory of things, motivated by considerations of quantified modal logic, can significantly further the persistence debate. We will use (...) our semantic framework to give an argument in support of the endurantist position as the best theory of persistence. (shrink)

This essay considers implications of formal mereologies and ontologies for medical metaphysics. Edward Fried’s extensional mereological account of the human body is taken as representative of a prominent strand in analytic metaphysics that has close affinities with medical positivism. I show why such accounts fail. First, I consider how Fried attempts to make sense of the medical case of Barney Clark, the first recipient of an artificial heart, and show that his analytic metaphysical categories do not have the right kind (...) of fit with the case. A proper medical metaphysic should involve a richer two way dialogue with medicine, and it should not just “apply” formal accounts worked out in other settings. Second, I argue that any effort to account for real wholes with extensional mereological sums requires all sorts of ad hoc, supplementary mechanisms that do the real work, and the full repertoire of these mechanisms involves inconsistencies and semantic shifts. Finally, I consider an alternative strand of work on non-extensional whole/part relations that is closer to medicine and that can deepen reflection on some core problems in bioethics, for example, associated with the determination of death when an organism ceases to function as a whole. In addition to the utility such formal ontologies have for addressing traditional problems such as the determination of death, philosophers of medicine should appreciate the increasingly influential role such formal tools are playing in the development of data system ontologies. Assumptions integral to these ontologies have far reaching implications for the way future research and practice in medicine will be conducted, and much greater critical reflection is needed on the full range of issues associated with the development and use of such medical ontologies.

I propose a minimal account of authorship that specifies the fundamental nature of the author-relation and its minimal domain composition in terms of a three-place causal-intentional relation holding between agents and sort-relative works. I contrast my account with the minimal account tacitly held by most authorship theories, which is a two-place relation holding between agents and works simpliciter. I claim that only my view can ground productive and informative principled distincitons between collective production and collective authorship.

In my argument for subject body dualism criticized by Ludwig I use the locution of a genuine and factual difference between two possibilities. Ludwig distinguishes three interpretations of this locution. According to his analysis the argument does not go through on any of these interpretations. In my response I agree that the argument is unsuccessful if ‘factual difference’ is understood in the first way. The second reading—according to a plausible understanding—cannot be used for the argument either. The discussion of this (...) reading raises fundamental issues about different notions of propositional content. I disagree with Ludwig's diagnosis with respect to the third reading. Contrary to Ludwig's claim, there is no modal error involved if ‘factual difference’ is understood in the third way. Ludwig's objection to the argument according to its third reading can be answered by pointing out that every individual has its identity conditions necessarily. At this point fundamental and general metaphysical issues (concerning the link between identity conditions and the nature of ontological categories and between transworld and transtemporal identity) prove relevant. Finally, I make more explicit how ‘factual difference’ should be understood in the context of the argument (this is a fourth reading not considered by Ludwig) and explain how this reading strengthens the argument (compared to the third reading) by weakening its central premise. I conclude that Ludwig's attempt at undermining the argument from transtemporal identity for subject body dualism is unsuccessful. (shrink)

The most basic divide amongst analytic metaphysicians separates realists from anti-realists. By examining certain characteristic and problematic features of these two families of views, we uncover their underlying metametaphysicalorientations, which turn out to coincide. This shared philosophical picture that underlies both the realist and the anti-realist project we call the Modern Picture. It rests on a crucial distinction between reality as it is for us and reality as it is in itself. It is argued that this distinction indeed generates the (...) realism/anti-realism dichotomy, and is also responsible for the problematic aspects highlighted earlier. We conclude by sketching an alternative philosophical picture that rejects the distinction between reality as it is for us and reality as it is in itself, which we call the Aristotelian Picture, and consider whether it is able to avoid the issues to which the Modern Picture gives rise.

This paper is divided in five sections. Section 11.1 sketches the history of the distinction between speech act with negative content and negated speech act, and gives a general dynamic interpretation for negated speech act. “Downdate semantics” for AGM contraction is introduced in Section 11.2. Relying on semantically interpreted contraction, Section 11.3 develops the dynamic semantics for constative and directive speech acts, and their external negations. The expressive completeness for the formal variants of natural language utterances, none of which is (...) a retraction, has been proved in Section 11.4. The last section gives a laconic answer to the question posed in the title of the paper. (shrink)

This is part I of a two-part essay introducing case-intensional first order logic, an easy-to-use, uniform, powerful, and useful combination of first-order logic with modal logic resulting from philosophical and technical modifications of Bressan’s General interpreted modal calculus. CIFOL starts with a set of cases; each expression has an extension in each case and an intension, which is the function from the cases to the respective case-relative extensions. Predication is intensional; identity is extensional. Definite descriptions are context-independent terms, and lambda-predicates (...) and -operators can be introduced without constraints. These logical resources allow one to define, within CIFOL, important properties of properties, viz., extensionality and absoluteness, Bressan’s chief innovation that allows tracing an individual across cases without recourse to any notion of “rigid designation” or “trans-world identity.” Thereby CIFOL abstains from incorporating any metaphysical principles into the quantificational machinery, unlike extant frameworks of quantified modal logic. We claim that this neutrality makes CIFOL a useful tool for discussing both metaphysical and scientific arguments involving modality and quantification, and we illustrate by discussing in diagrammatic detail a number of such arguments involving the extensional identification of individuals via absolute properties, essential properties, de re vs. de dicto, and the results of possible tests.

This paper examines David Hull’s and Peter Godfrey-Smith’s accounts of biological individuality using the case of biofilms. Biofilms fail standard criteria for individuality, such as having reproductive bottlenecks and forming parent-offspring lineages. Nevertheless, biofilms are good candidates for individuals. The nature of biofilms shows that Godfrey-Smith’s account of individuality, with its reliance on reproduction, is too restrictive. Hull’s interactor notion of individuality better captures biofilms, and we argue that it offers a better account of biological individuality. However, Hull’s notion of (...) interactor needs more precision. We suggest some ways to make Hull’s notion of interactor and his account of individuality more precise. Generally, we maintain that biofilms are a good test case for theories of individuality, and a careful examination of biofilms furthers our understanding of biological individuality. (shrink)

Accounts of act individuation have attempted to capture peoples’ pre-theoretic intuitions. Donald Davidson has argued that a multitude of action descriptions designate only one act, while Alvin Goldman has averred that each action description refers to a distinct act. Following on recent empirical studies, I subject these accounts of act individuation to experimentation. The data indicate that people distinguish between actions differently depending upon the moral valence of the outcomes. Thus, the assumption that a single account of act individuation applies (...) invariantly seems mistaken. (shrink)

My starting point is that discussions in philosophy about the ontology of technical artifacts ought to be informed by classificatory practices in engineering. Hence, the heuristic value of the natural-artificial distinction in engineering counts against arguments which favour abandoning the distinction in metaphysics. In this chapter, I present the philosophical equipment needed to analyse classificatory practices and then present a case study of engineering practice using these theoretical tools. More in particular, I make use of the Collectivist Account of Technical (...) Artifacts (CAT) according to which there are different classificatory practices for natural, artificial, and social objects. I demonstrate that in the community studied, artificial kinds are marked by distinctive classificatory practices. The presence of these distinctive classificatory practices in engineering with regard to artificial kinds should inform discussions about the ontology of technical artifacts just as the distinctive classificatory practices in natural science inform discussions about natural kinds.

The word ‘dignity’ is used in a variety of ways in bioethics, and this ambiguity has led some to argue that the term must be expunged from the bioethical lexicon. Such a judgment is far too hasty, however. In this article, the various uses of the word are classified into three serviceable categories: intrinsic, attributed, and inflorescent dignity. It is then demonstrated that, logically and linguistically, the attributed and inflorescent meanings of the word presuppose the intrinsic meaning. Thus, one cannot (...) conclude that these meanings are arbitrary and unrelated. This categorization and logical and linguistic analysis helps to unravel what seem to be contradictions in discourse about dignity and bioethics, and provides a hierarchy of meaning that has potential normative implications.

The paper takes off from the problem of finding a proper content for the relation of identity as it holds or fails to hold among ordinary things or substances. The necessary conditions of identity are familiar, the sufficient conditions less so. The search is for conditions at once better usable than the Leibnizian Identity of Indiscernibles (independently suspect) and strong enough to underwrite all the formal properties of the relation.It is contended that the key to this problem rests at the (...) level of metaphysics and epistemology alike with a sortalist position. Sortalism is the position which insists that, if the question is whether a and b are the same, it has to be asked what are they? Any sufficiently specific answer to that question will bring with it a principle of activity or functioning and a mode of behaviour characteristic of some particular kind of thing by reference to which questions of persistence or non-persistence through change can be adjudicated.These contentions are illustrated by reference to familiar examples such as the human zygote, the Ship of Theseus and Shoemaker's Brown-Brownson. The first example is hostage for a mass of unproblematical cases. The problems presented by the second and third sort of examples arise chiefly (it is claimed) from an incompleteness in our conceptions of the relevant sort—the what the thing in question is. That incompleteness need not prevent us from knowing perfectly well which thing we are referring to. In the concluding section, sortalism is defended against various accusations of anthropocentrism.The paper touches on the interpretation of Heraclitus, Leibniz's theory of clear indistinct ideas, the difficulties of David Lewis's ‘perdurantist’ or stroboscopic view of persistence, four-dimensionalism, and the relation of personal identity both to experiential memory and to the particular bodily physiognomy of a subject. At some points—as in connection with the so-called Only a and b rule—the paper corrects, supplements or extends certain theses or formulations proposed in the author's Sameness and Substance Renewed (2001).

Using the Hilbert-Bernays account as a spring-board, we first define four ways in which two objects can be discerned from one another, using the non-logical vocabulary of the language concerned. Because of our use of the Hilbert-Bernays account, these definitions are in terms of the syntax of the language. But we also relate our definitions to the idea of permutations on the domain of quantification, and their being symmetries. These relations turn out to be subtle---some natural conjectures about them are (...) false. We will see in particular that the idea of symmetry meshes with a species of indiscernibility that we will call `absolute indiscernibility'. We then report all the logical implications between our four kinds of discernibility. We use these four kinds as a resource for stating four metaphysical theses about identity. Three of these theses articulate two traditional philosophical themes: viz. the principle of the identity of indiscernibles, and haecceitism. The fourth is recent. Its most notable feature is that it makes diversity weaker than what we will call individuality : two objects can be distinct but not individuals. For this reason, it has been advocated both for quantum particles and for spacetime points. Finally, we locate this fourth metaphysical thesis in a broader position, which we call structuralism. We conclude with a discussion of the semantics suitable for a structuralist, with particular reference to physical theories as well as elementary model theory. (shrink)

According to Essentialism, an object’s properties divide into those that are essential and those that are accidental. While being human is commonly thought to be essential to Socrates, being a philosopher plausibly is not. We can motivate the distinction by appealing—as we just did—to examples. However, it is not obvious how best to characterize the notion of essential property, nor is it easy to give conclusive arguments for the essentiality of a given property. In this paper, I elaborate on these (...) issues and explore the way in which essential properties behave in relation to other related properties, like sufficient-for-existence properties and individual essences.

This paper maintains (following Yougrau 1987; 2000 and Hinchliff 1996) that the dead and other former existents count as examples of non-existent objects. If the dead number among the things there are, a further question arises: what is it to be dead—how should the state of being dead be characterised? It is argued that this state should be characterised negatively: the dead are not persons, philosophers etc. They lack any of the (intrinsic) qualities they had while they lived. The only (...) facts involving the dead are facts about the relations they stand in—including the relations they bear to the qualities they formerly instantiated, and the intentional relations they stand in to us. Given an appropriate conception of qualities the dead can be said to be quality-less objects: bare particulars. The ‘Bare Particular Theory’ of individuals, it is argued, is coherent if and only if it concedes that the bare particulars it allows for don’t exist. The account of the dead and other former existents as bare particulars does justice to the misfortune of death, and points the way to a general theory of nonexistent objects. (shrink)

Monists about material constitution typically argue that when Statue is materially constituted by Clay, Statue is just Clay. Pluralists about material constitution deny that constitution is identity: Statue is not just Clay. When Clay materially constitutes Statue, Clay is not identical to Statue. I discuss three familiar puzzles involving grounding, overdetermination and conceptual issues, and develop three new puzzles stemming from the connection between mereological composition and material constitution: a mereological puzzle, an asymmetry puzzle, and a structural puzzle.

According to one argument for Animalism about personal identity, animal , but not person , is a Wigginsian substance concept—a concept that tells us what we are essentially. Person supposedly fails to be a substance concept because it is a functional concept that answers the question “what do we do?” without telling us what we are. Since person is not a substance concept, it cannot provide the criteria for our coming into or going out of existence; animal , on the (...) other hand, can provide such criteria. This argument has been defended by Eric Olson, among others. I argue that this line of reasoning fails to show Animalism to be superior to the Psychological Approach, for the following two reasons: (1) human animal , animal , and organism are all functional concepts, and (2) the distinction between what something is and what it does is illegitimate on the reading that the argument needs.

Tyler Burge argues on the basis of an account of memory that the notion of quasimemory cannot be used to answer the circularity objection to psychological accounts of personal identity. His account implies the impossibility of the "Parfit people," creatures psychologically like us who undergo amoeba-like fission at the age of twenty-one, with only one offshoot allowed to survive, and who have "quareers," made up of the career of the original person and the career of the sole survivor, that exhibit (...) the same sort of psychological continuity that characterizes normal human careers, and are such that epistemic warrant is preserved across the episodes of fission and often involves quasimemories that are not memories. But what he says about memory does not support the denial that such creatures are possible. Where he thinks de se attitudes are necessary, de se * attitudes, indexed to quareers instead of to careers, would serve equally well. It is further argued that the circularity objection to psychological accounts can be answered without appeal to the notion of quasi-memory. Because of the internal relations between the causal profiles of mental states and the persistence conditions of their possessors, in principle there can be a "package deal" definition that simultaneously defines both. (shrink)

I defend the view that ordinary objects like statues are identical to the pieces of matter from which they are made. I argue that ordinary speakers assert sentences such as ‘this statue is a molded piece of clay’. This suggests that speakers believe propositions which entail that ordinary objects such as statues are the pieces matter from which they are made, and therefore pluralism contradicts ordinary beliefs. The dominant response to this argument purports to find an ambiguity in the word (...) ‘is’, such that ‘is’ in these sentences means the same as ‘constitutes or is constituted by’. I will use standard tests for ambiguity to argue that this strategy fails. I then explore and reject other responses to the argument. (shrink)

Particularists in material-object metaphysics hold that our intuitive judgments about which kinds of things there are and are not are largely correct. One common argument against particularism is the argument from arbitrariness, which turns on the claim that there is no ontologically significant difference between certain of the familiar kinds that we intuitively judge to exist (snowballs, islands, statues, solar systems) and certain of the strange kinds that we intuitively judge not to exist (snowdiscalls, incars, gollyswoggles, the fusion of the (...) my nose and the Eiffel Tower). Particularists frequently respond by conceding that there is no ontologically significant difference and embracing some sort of deflationary metaontology (relativism, constructivism, quantifier variance). I show -- by identifying ontologically significant differences -- that the argument can be resisted without retreating to any sort of deflationary metaontology. (shrink)

The self/non-self model, first proposed by F.M. Burnet, has dominated immunology for 60 years now. According to this model, any foreign element will trigger an immune reaction in an organism, whereas endogenous elements will not, in normal circumstances, induce an immune reaction. In this paper we show that the self/non-self model is no longer an appropriate explanation of experimental data in immunology, and that this inadequacy may be rooted in an excessively strong metaphysical conception of biological identity. We suggest that (...) another hypothesis, one based on the notion of continuity, gives a better account of immune phenomena. Finally, we underscore the mapping between this metaphysical deflation from self to continuity in immunology and the philosophical debate between substantialism and empiricism about identity.

I set up a dilemma, concerning metaphysical modality de re, for the essentialist opponent of a ‘two senses’ view of necessity. I focus specifically on Frank Jackson's two-dimensional account in his From Metaphysics to Ethics (Oxford: Oxford University Press, 1998). I set out the background to Jackson's conception of conceptual analysis and his rejection of a two senses view. I proceed to outline two purportedly objective (as opposed to epistemic) differences between metaphysical and logical necessity. I conclude that since one (...) of these differences must hold and since each requires the adoption of a two senses view of necessity, essentialism is not consistent with the rejection of a two senses view.

Beginning with Aristotle, philosophers have taken artifacts to be ontologically deficient. This paper proposes a theory of artifacts, according to which artifacts are ontologically on a par with other material objects. I formulate a nonreductive theory that regards artifacts as constituted by - but not identical to - aggregates of particles. After setting out the theory, I rebut a number of arguments that disparage the ontological status of artifacts.

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist supposes that some such episodes have as constituents mind-independent objects. In turn, the disjunctivist claims that in a case of (...) veridical perception like this very kind of experience that you now have, the experiential episode you enjoy is of a kind which could not be occurring were you having an hallucination. The common strategy of arguments from hallucination set out to show that certain things are true of hallucinations, and hence must be true of perceptions. For example, it is argued that hallucinations must have non-physical objects of awareness, or that such states are not relations to anything at all, but are at best seeming relations to objects. In insisting that veridical perceptual experience is of a distinct kind from hallucination, the disjunctivist denies that any of these conceptions of hallucination challenges our conception of veridical perceptions as relations to mind-independent objects. More specifically, I assume that the disjunctivist advocates naïve realism because they think that this position best articulates how sensory experience seems to us to be just through reflection. If the disjunctivist is correct in this contention, then anyone who accepts the conclusion of the argument from hallucination must also accept that the nature of sensory experience is other than it seems to us to be. In turn, one may complain that any such error theory is liable to lead to sceptical consequences. A Humean scepticism about the senses launches a challenge about our knowledge of the world through questioning the conception we have of what sense experience is, and how it can provide knowledge of the world.

Semantic externalism in contemporary philosophy of language typically – and often tacitly – combines two supervenience claims about idiolectical meaning (i.e., meaning in the language system of an individual speaker). The first claim is that the meaning of a word in a speaker’s idiolect may vary without any variation in her intrinsic, physical properties. The second is that the meaning of a word in a speaker’s idiolect may vary without any variation in her understanding of its use. I here show (...) that a conception of idiolectical meaning is possible that accepts the “anti-internalism” of the first claim while rejecting (what I shall refer to as) the “anti-individualism” of the second. According to this conception, externally constituted idiolectical meaning supervenes on idiolectical understanding. (shrink)

Questions of persistence and change are central to metaphysics. There is almost always a role for sortal or essential properties to play in theories of persistence. However, one might reasonably be suspicious of many of the claims about sortal properties and essential properties on which so many accounts of persistence conditions rest. The aim of this paper is to think through what persistence looks like if we don't help ourselves to these assumptions. In so doing, we shall uncover a deep (...) and difficult problem when it comes to identity facts and their relation to qualitative facts. Towards the end of the paper, I sketch a potential line of response that builds upon our seeming awareness of a genuinely persisting self. (shrink)

Extensive and critical review of Perception and Reality in Kant, Husserl and McDowell, written by van Mazijk, Corijn focussing on his discussion of McDowell.

The paper aims to offer an account of the cognitive capacities involved in judgements about thought experiments, without appealing to the notions of analyticity or intuition. I suggest that we employ a competence in the application of the relevant concepts. In order to address the worry that this suggestion is not explanatory, I look at some theories of concepts discussed in psychology, and I use them to illustrate how such competence might be realized. This requires, crucially, distinguishing between concepts and (...) ways of applying concepts, or conceptions. I end by considering a possible objection and comparing my account with a similar one defended by David Papineau. (shrink)

Artifacts are ubiquitous and influential in our world, but their nature and existence are controversial. Several theories have been proposed to explain the ontology of artifacts. Drawing on Popper's theory of three worlds, this paper suggests a metaphysics for artifacts along the line of a critical rationalist (CR) approach. This theory distinguishes between three realms of reality: the physical world (World 1), the mental world (World 2), and the world of objective knowledge (World 3). The paper argues that artifacts have (...) different ontological components that correspond to these three realms, and that each component is real and causal. The paper shows how this perspective can account for the intentional and functional aspects of artifacts, as well as their dependence on plans that influence different realms of reality. The paper explains how this pluralistic ontology, compared to the rival theories, enables one to explain the relevant ontological problems of artifacts. The paper also explores how this proposal can lead to a research program encompassing a broader range of technologies, such as social artifacts. In sum, the paper suggests that Popper's three worlds theory provides a rich and comprehensive framework for understanding the metaphysics of artifacts. (shrink)

Mereological atomism is the thesis that everything is ultimately composed of atomic parts, i.e., parts without proper parts. Typically, this thesis is characterized by an axiom stating that everything has atomic parts. The present paper argues that the success of this standard characterization depends on how the notions of sum and composition are defined. In particular, we put forward a novel definition of mereological sum that: (i) is not equivalent to existing definitions in the literature, if no strong decomposition principle (...) is assumed; (ii) can be used to argue that the standard characterization of atomism fails, because having atomic parts is not sufficient to be a sum of atoms; and (iii) provides a purely mereological distinction between structured and unstructured wholes, contributing to the ongoing debate on this crucial topic.

Late Lowe’s metaphysics of material objects is an interesting multi-thingist theory that still attracts interest from various authors. The core idea is that ifxmaterially constitutesy, thexis a proper part ofy. I discuss some mereological issues that arise from the approach and propose a revision of the mereology associated. Particularly, I examine the tenability of a number of supplementation principles and conclude that just one may serve the theory adequately. Still, the endorsement of such a principle does not come for free. (...) Successively, I address the derivability of an important extensionality theorem and conclude that the theorem must be taken as an axiom in the mereology at stake. Lastly, I discuss two notable definitions of mereological fusions to assess which one best suits the present theory. The result is that authors sharing Lowe’s multi-thingist conception of material objects can still enjoy a moderately strong mereology. (shrink)

In Metaphysics Γ, Aristotle argues against those who seem to accept contradictions. He distinguishes between the Sophists, who deny the principle of non-contradiction through arguments, and the Natural Philosophers, whose physical investigations lead to the acceptance of objective contradictions. Heraclitus’ name appears throughout the discussion. Usually, he is associated with the discussion against the Sophists. In this paper, I explore how the discussion with the Natural Philosophers may illuminate both the interpretation of Heraclitus by Aristotle and Heraclitus’ own worldview. To (...) refute the Natural Philosophers, Aristotle proposes a general reconstruction of their reasoning. Roughly, relying on sensory evidence (A1), they see that the same thing changes from one opposite to another (A2). Such a change appears to characterize a generation out of non-being, which a Natural Philosopher does not accept (A3). To solve the problem, despite their different worldviews, Natural Philosophers hint at a state in which opposites co-occur, characterizing an objective contradiction (C). Looking at the discussion in Metaphysics Γ and Heraclitus fragments, sections 1–3 show how assumptions A1, A2, and A3 easily apply to Heraclitus. The case of the conclusion is more challenging. In the case of the Pluralists, the co-existence of opposites characterizes a state in which there is no generation. Such a view does not fit Heraclitus’ mobilism. To argue that Aristotle’s argument is general enough to encompass dynamic views, I examine his problematization of accepting the change of change in Metaphysics K and Physics V. There, after re-stating several points that appear in Metaphysics Γ, Aristotle argues that accepting the becoming of another becoming leads to a state of contradiction in which the becoming is perishing. Heraclitus’ B8, cited in Nicomachean Ethics, gives evidence that, for Aristotle, Heraclitus puts a process at the origin of an opposite process. Moreover, after examining the expression ‘living the death/dying the life’ in B62, I argue that Heraclitus was aware that his worldview implied a dynamic objective contradiction. Finally, an analysis of elemental changes in B36 proves that accepting objective contradictions does not make Heraclitus’ worldview less attractive. (shrink)

This paper argues that the substance concept, as discussed by Aristotle in his Categories, aids us to improve our understanding of human nature. Aristotle distinguished the primary from the secondary substance, and substantial from accidental change. We explain these distinctions, their use for understanding phenomena, and discuss how we can integrate them with evolutionary explanations of human nature. For explaining of how the typical human characteristics evolved, we extend our investigations with a discussion of the concept of person. It is (...) argued that psychological attributes, used to characterize persons, are not attributes of a separate mental substance, as Cartesians believe. The concept of a person, though not a substance concept, qualifies a substance concept of a human being possessing rational powers. The latter evolved as the result of language evolution. (shrink)

Among those who posit properties, liberals (mostly nominalists) admit abundant, ontologically free properties, which particulars possess whenever they satisfy the same predicate and belong to the same class, however artificial. I call them “L-properties” (for “Liberal”). Some liberals also admit that some few L-properties are natural, while most of them are artificial (the same applies to the corresponding classes). Others (mostly but not only realists) commit to a more discriminating use of the category: properties are sparse, they make for the (...) objective similarities among particulars, and more importantly, they allow to analyze “objective similarity” and “class naturalness” in terms of property-possessing and sharing. They give particulars their “true nature”, and I call them “A-properties” (for “Analytical”). This article provides a defense of this second type of properties, in the particular case of sortals. To that end, a new fact is put forward: that sorts are classes which are natural not as a primitive feature, but in virtue of what the particulars which belong to them are, and which makes them _naturally belong_ to them. I then argue that this fact entails the existence of the desired type of properties, “sortal A-properties”, although leaving open the question of how they should be construed. (shrink)

Certain contemporary philosophers have thought that the first-person, qualitative aspect of conscious experience should be taken seriously when it comes to our thinking about personal identity through time. These philosophers have thus argued that experiential continuity is essential to a person’s ability to persist identically through time. This is what I will call ‘the phenomenological theory’. In this thesis I describe the phenomenological theory and then discuss three problems that have plagued the history of this theory: the bridge problem, the (...) token problem, and the ontological problem. I will argue that a recent version of the phenomenological theory proposed by Barry Dainton and Timothy Bayne provides satisfactory answers to two of these problems, but not the third. I will conclude this thesis by proposing a superior version of the phenomenological theory—one that can handle all three problems. (shrink)

Eli Hirsch argues that certain ontological disputes involve a conflict between “equivalent” languages, and that the principle of charity compels each disputant to interpret the other as speaking truly in their own language. For Hirsch, a language’s semantics maps sentences (in context) onto sets of possible worlds but assigns no role to reference. I argue that this method leads to an overly uncharitable portrayal of the disputes at issue – whereby ontologists who speak “equivalent” languages can only argue about syntax. (...) Lack of charity stems from the fact that this portrayal likely fails to uphold the self-conception of the disputants – and particularly what I will call “the weak self-conception”. As a result, Hirsch’s deflationism falls victim of the same principle of charity that informs it. (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.

Life, whatsoever it is, is a temporal flux. Everything is doomed to change often apparently beyond our awareness. My body appears totally different now, so does my mind. I have gained new attitudes and new ambitions, and a substantial number of old ones have been discarded. But, I am still the same person in an ongoing manner. Besides, recent neuroscientific and psychological evidence has shown that our conscious perception happens as a series of discrete or bounded instants—it emerges in temporally (...) scattered, gappy, and discrete forms. But, if it is so, how does the brain persevere our self-continuity in this gappy setting? How is it possible that despite moment-to-moment changes in my appearance and mind, I am still feeling that I am that person? How can we tackle with this second by second gap and resurrection in our existence which leads to a foundation of wholeness and continuity of our self? How is continuity of self that results in a feeling that one’s life has purpose and meaning preserved? To answer these questions, the problem has been comprehended from a philosophical, psychological, and neuroscientific perspective. I realize that first and foremost fact lies in the temporal nature of identity. Having equipped with these thoughts, in this article, it is hypothesized that according to two principles self-continuity is maintained. It is supposed that there should be a precise temporal integration mechanism in the CNS with the outside world that provides us this smooth, ungappy flow of the Self. However, we are often taken for granted the importance of self-continuity, but it can be challenged by life transitions such as entering adulthood, retirement, senility, emigration, and societal changes such as immigration, globalization, and in much unfortunate and extreme cases of mental illnesses such as schizophrenia.

Good physical experiments conform to the basic methodological standards of experimental design: they are objective, reliable, and valid. But is this also true of thought experiments? Especially problems of personal identity have engendered hypothetical scenarios that are very distant from the actual world. These imagined situations have been conspicuously ineffective at resolving conflicting intuitions and deciding between the different accounts of personal identity. Using prominent examples from the literature, I argue that this is due to many of these thought experiments (...) not adhering to the methodological standards that guide experimental design in nearly all other disciplines. I also show how empirically unwarranted background assumptions about human physiology render some of the hypothetical scenarios that are employed in the debate about personal identity highly misleading.

This article outlines a realist theory of aesthetic properties as higher-order manifest properties and defends it from several objections, including a possible conflict with contextualist approaches to the aesthetic properties of works of art.

Based on a large cross-cultural study, David Rose and his colleagues (2020) argue that the Ship of Theseus story is a genuine puzzle in the sense that people who consider it feel inclined to assert two prima facie inconsistent propositions (Ambivalence). In response, Marta Campdelacreu and her colleagues (2020) argue that the data reported by Rose et al. (2020) fail to support Ambivalence. Namely, the data show sharp interpersonal disagreement among different readers of the Ship of Theseus story, but they (...) fail to demonstrate an intrapersonal conflict or indecision. Should intrapersonal Ambivalence be demonstrated, this, according to Campdelacreu et al. (2020), would be a good indicator of the presence of a puzzle. Here, I provide empirical evidence for intrapersonal Ambivalence about the Ship of Theseus story. (shrink)

In this article I provide an analysis of some salient concepts of dignity. The text is a development of a work which was initiated in the year 2000 in the research programme Dignity and Older Europeans supported by the European Union. The programme was both theoretical and empirical. The empirical part, which was the most comprehensive, consisted of focus-group interviews with health care and social care personnel, elderly persons within health care or social care, and representatives from the general public. (...) The interviews concerned the care of the elderly and attitudes towards the elderly. Some questions concerned how the interviewees conceived the concept of dignity and what they meant by behaviour respectful of dignity in the care of the elderly. Altogether around 1000 focus-group interviews were conducted in seven of the countries involved. The theoretical part of the programme consisted of an analysis of the concepts of dignity based on studies of dictionary entries in six languages as well as previous philosophical analyses of the concept. In the theoretical part of the study there emerged four different concepts of dignity: dignity of merit, dignity of moral standing, dignity of identity and human dignity. Characterizations of these concepts have been presented and developed in several publications, for example Nordenfelt and. In the present article this analysis is taken a step further. I take as a starting point some previous studies, including Schroeder, Sulmasy and my earlier ones, and propose an improvement and clarification of my earlier classification of dignities. At the same time I enlarge the analysis to concern worths in general and how these are attached to entities in general, not just human beings. The four kinds of dignities which I now propose are called: attributed dignity, dignity of inflorescence, dignity of identity and human dignity. (shrink)

A popular claim in recent philosophy of mind and action is that events only exist once they are over. This has been taken to have the consequence that many temporal phenomena cannot be understood ‘from the inside’, as they are unfolding, purely in terms of events. However, as I argue here, the claim that events exist only when over is incoherent. I consider two ways of understanding the claim and the notion of existence it involves: one that ties existence to (...) the logic of quantification, and another that assimilates the existence of an event to that of a continuant. The first of these, I argue, cannot be the right way to understand the target claim, as there are serious logical obstacles to regarding this notion of existence as temporally variable. The second, on the other hand, leaves it ultimately mysterious what the existence of an event could amount to. I close with the suggestion that the undeniable temporal asymmetries which parties to the debate are interested in are properly understood in perspectival, not ontological, terms. (shrink)

Debates about material coincidence tend to start with common-sense intuitions but quickly leave them behind and lead to highly problematic conclusions. Reconciling the latter with common sense is the next stage in the process, which often requires revision of some of the initial beliefs and has been used to adjudicate many rather abstract and technical proposals in the metaphysics of composition and persistence, ranging from natural (constitutionalism) to radical (nihilism). -/- I have no disagreement with this overall strategy: theories do (...) need to turn abstract at some point, move beyond common sense, and eventually force upon us interesting, novel, and often counterintuitive revisions in our overall conceptual scheme. This applies to all theoretical areas, and contemporary metaphysics is no exception. But while the latter is widely regarded as being quite extreme in this respect, I want to argue that, in one sense, it is not extreme enough. I do it by developing a new case of material coincidence that is initially motivated not by common sense but by physical considerations, and is not susceptible to any of the standard solutions. -/- One lesson of science is its ability to expand our imagination beyond the limits of common sense. This may have importance for metaphysics too. (shrink)

It is often claimed that the social sciences cannot be reduced to a lower-level individualistic science. The standard argument for this position is the Fodorian multiple realizability argument. Its defenders endorse token–token identities between “higher-level” social objects and pluralities/sums of “lower-level” individuals, but they maintain that the properties expressed by social science predicates are often multiply realizable, entailing that type–type identities between social and individualistic properties are ruled out. In this paper I argue that the multiple realizability argument for explanatory (...) holism is unsound. The social sciences are indeed irreducible, but the principled reason for this is that the required token–token identifications cannot in general be carried through. In consequence, paradigmatic social science predicates cannot be taken to apply to the objects quantified over in the lower-level sciences. The result is that typical social science predicates cannot even be held to be co-extensive with individualistic predicates, which means type–type identifications are ruled out too. Multiple realizability has nothing to do with this failure of co-extensiveness, because the relevant social science predicates are not multiply realized in the sense intended by the explanatory holists, a sense which presupposes reductive token–token identifications.

I argue there are some objects which do not respect the Law of the Excluded Middle, i.e., which are such that, for some property F, the disjunction Fo v ~Fo fails to be true. I call such objects “odd objects” and present three examples—fictional objects, nonsort objects, and quantum objects. I argue that each of these objects is best understood as violating LEM. I, then, discuss Jessica Wilson’s account of metaphysical indeterminacy. I show how the indeterminacy which arises with odd (...) objects can be accounted for on Wilson’s account. I, then, argue that my Wilson-inspired, but non-LEM-respecting, account of metaphysical indeterminacy is superior to Wilson’s in terms of costs and benefits. (shrink)

In this article, I argue that our ontology of art has undergone a major change in the course of modern history. While we currently think of artworks as parts arranged in a certain way, there was a time when artworks were thought of as metaphysically more akin to ordinary artefacts such as tables and chairs; that is, as wholes having replaceable parts. This change in our ontology of art is reflected in our approach to art restoration. But what explains the (...) change? I will suggest that the change took place because of a change in our conception of the function of art. More specifically, I will suggest that we have started to think of artworks as parts arranged in a certain way, because we have started to think of artworks as having, primarily, an aesthetic function.
