Este trabajo presenta y discute diferentes intentos recientes para resolver el así llamado «problema de la Trinidad». Las declaraciones dogmáticas han asumido que (a) sólo hay un Dios; (b) que hay tres personas diferentes, el Padre, el Hijo y el Espíritu Santo; y (c) que esas tres personas son un solo Dios. Pero si hay tres personas diferentes y esas tres personas diferentes son Dios, entonces parece que, o bien no hay un único Dios, o no hay realmente tres personas (...) diferentes. Han aparecido cuatro posiciones principales en el debate reciente en Teología Filosófica para resolver este problema: (i) la teoría social de la Trinidad, (ii) la teoría «latina» de la Trinidad, (iii) la teoría de la Trinidad basada en identidades relativas, y (iv) la teoría de la Trinidad basada en relaciones de constitución. Se presentan y discuten críticamente las cuatro posiciones. This work presents and discusses different recent attempts to solve the so-called «problem of the Trinity». The dogmatic declarations have assumed that: (a) there is only one God; (b) that there are three different persons, the Father, the Son, and the Holy Spirit; and (c) that those three persons are just one God. But if there are three different persons and those three different persons are God, then it seems that, either there is not just one God, or there are not really three different persons. There have appeared four main positions in the recent debate in Philosophical Theology to solve this problem: (i) the social theory of the Trinity, (ii) the «latin» theory of the Trinity, (iii) the theory of the Trinity based on relative identity, and (iv) the theory of the Trinity based on relations of constitution. All four positions are presented and critically discussed. (shrink)

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.

The following Review Essay, inspired by Tracy Isaacs’ new book, Moral Responsibility in Collective Contexts, connects the philosophical literature on group agency with recent trends in international criminal law. Part I of the Essay sketches out the relevant philosophical positions, including collectivist and individualist accounts of group agency. Particular attention is paid to Kornhauser and Sager’s development of the doctrinal paradox, Philip Pettit’s deployment of the paradox towards a general argument for group rationality, and Michael Bratman’s account of shared or (...) joint intentions. Part II then analyzes, with cautious support, Isaacs’ two-level solution, which entails both individual and collective moral responsibility. Under this view, collective moral agency is a real phenomenon, though the existence of the collective neither obviates nor eliminates the moral responsibility of the individuals from which it is composed. My own evaluation of the proposed solution concentrates on Davidson’s Principle of Charity and whether behavior interpretation requires viewing such agents in particular ways so as to maximize rationality. By analogy to the distinctive rationality of long-term plans, where the rationality of an individual act can only be understood relative to its place in the rationally justified long-term plan of a single individual, I also consider the rationality of individual acts whose rationality can only be understood relative to the group endeavors of which they are a part. Finally, Part III traces some implications of the two-level solution for legal doctrine, in particular the role of collective organizations in the recent jurisprudence of the International Criminal Court. For example, I note that the ICC has recently become more and more focused on the role played by goal-oriented collectives, especially with regard to the plan or policy requirement for crimes against humanity and, in the context of modes of liability, indirect liability for crimes committed through an organization.

The general question (G) How do we categorize artifacts? can be subject to three different readings: an ontological, an epistemic and a semantic one. According to the ontological reading, asking (G) is equivalent to asking in virtue of what properties, if any, a certain artifact is an instance of some artifact kind: (O) What is it for an artifact a to belong to kind K? According to the epistemic reading, when we ask (G) we are investigating what properties of the (...) object we exploit in order to decide whether a certain artifact belongs to a certain kind. (G) thus becomes: (E) How can we know that artifact a belongs to kind K? Finally, (G) can also be read as a question concerning the semantics of artifact kind terms. The semantic reading of (G) is: (S) What kind of reference do artifact kind terms have, if any? In this editorial we expand on the different answers to (O), (E) and (S) that are given in the selected literature on the topic. The result should give us an overall picture of the possible answers to (G). (shrink)

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)

Unger has recently argued that if you are the only thinking and experiencing subject in your chair, then you are not a material object. This leads Unger to endorse a version of Substance Dualism according to which we are immaterial souls. This paper argues that this is an overreaction. We argue that the specifically Dualist elements of Unger’s view play no role in his response to the problem; only the view’s structure is required, and that is available to Unger’s opponents. (...) We outline one such non-Dualist view, suggest how to resolve the dispute, respond to some objections, and argue that ours is but one of many views that survive Unger’s challenge. All these views are incompatible with microphysicalism. So Unger’s discussion does contain an insight: if you are the only conscious subject in your chair, then microphsyicalism is false. Unger’s mistake was to infer Substance Dualism from this; for microphysicalism is not the only alternative to Dualism. (shrink)

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)

Meta-ontology (in van Inwagen's sense) concerns the methodology of ontology, and a controversial meta-ontological issue is to what extent ontology can rely on linguistic analysis while establishing the furniture of the world. This paper discusses an argument advanced by some ontologists (I call them unifiers) against supporters of or coincident entities (I call them multipliers) and its meta-ontological import. Multipliers resort to Leibniz's Law to establish that spatiotemporally coincident entities a and b are distinct, by pointing at a predicate F (...) () made true by a and false by b . Unifiers try to put multipliers in front of a dilemma: in attempting to introduce metaphysical differences on the basis of semantic distinctions, multipliers either (a) rest on a fallacy of verbalism, entailed by a trade-off between a de dicto and a de re reading of modal claims, or (b) beg the question against unifiers by having to assume the distinction between a and b beforehand. I shall rise a tu quoque, showing that unifiers couldn't even distinguish material objects (or events) from the spatiotemporal regions they occupy unless they also resorted to linguistic distinctions. Their methodological aim to emancipate themselves from linguistic analysis in ontological businesses is therefore problematic. (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)

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 metaphor of a branching tree of future possibilities has a number of important philosophical and logical uses. In this paper we trace this metaphor through some of its uses and argue that the metaphor works the same way in physics as in philosophy. We then give an overview of formal systems for branching possibilities, viz., branching time and (briefly) branching space-times. In a next step we describe a number of different notions of possibility, thereby sketching a landscape of possibilities. (...) In the final section of the paper we look at the place of branching-based possibilities in that larger landscape of possibilities. Our main message is that far from being an outlandish metaphysical extravagancy, branching-based possibilities are epistemically as well as metaphysically basic. (shrink)

Two problems related to the biological identity of living beings are faced: the who-problem (which are the biological properties making that living being unique and different from the others?); the persistence-problem (what does it take for a living being to persist from a time to another?). They are discussed inside a molecular biology framework, which shows how epigenetics can be a good ground to provide plausible answers. That is, we propose an empirical solution to the who-problem and to the persistence-problem (...) on the basis of the new perspectives opened by a molecular understanding of epigenetic processes. In particular, concerning the former, we argue that any living being is the result of the epigenetic processes that have regulated the expression of its genome; concerning the latter, we defend the idea that the criterion for the persistence of its identity is to be indicated in the continuity of those epigenetic processes. We also counteract possible objections, in particular (1) whether our approach has something to say at a metaphysical level; (2) how it could account for the passage from the two phenotypes of the parental gametes to the single phenotype of the zygote; (3) how it could account for the identity of derivatives of one living being that continue to live disjoined from that original living being; (4) how it could account for higher mental functions.

Recently, several authors have claimed to have found graph-theoretic counterexamples to the Principle of the Identity of Indiscernibles. In this paper, I argue that their counterexamples presuppose a certain view of what unlabeled graphs are, and that this view is optional at best.

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 asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong reasons for thinking that such conventionality is impossible, it is desirable that our metaphysical-cum-semantic (...) theories of persistence be able to account for such scenarios in terms of conventions of the first kind. Later parts of the article therefore investigate whether three of the currently most influential metaphysical-cum-semantic theories of persistence—the endurance theory, the stage theory, and the perdurance theory—can do this. Fortunately, for them, it turns out that all can, though some philosophers have disputed this. However, when we ask how they account for a typical case of “conventional persistence” some problematic features of the theories—having to do with reference, persistence conditions, how they relate, and the epistemology of persistence—are revealed.

In the past few years, deflationary positions in the debate on the nature of composite material objects have become prominent. According to Ted Sider these include the thesis of quantifier variance, against which he has defended ontological realism. Recently, Sider has considered the possibility of rejecting his arguments against the vagueness of the unrestricted quantifiers in terms of translation functions. Against this strategy, he has presented an intuitive complaint and has argued that it can only be resisted if quantifier variance (...) is accepted. But this is false. In this paper I argue, against Sider, that there is a coherent way to combine the rejection of quantifier variance with the vagueness of the unrestricted quantifiers. I sketch a model to show this, and then I consider, on the basis of it, several versions of the indeterminacy argument against the vagueness of the unrestricted quantifiers that Sider has formulated over the years.

I discuss E. J. Lowe's conception of criteria of identity and sketch a different and, I think, more adequate conception. On my view, criteria of identity are some of the things we can do. They are what we do when distinguishing between single entities of the kind in question and pairs of entities of the relevant domain. And they enable us to make such distinctions because they are applicable to all single and to all pairs of entities of the relevant (...) domain but fulfilled only by all single entities of the kind in question. This feature of criteria of identity allows us to define these criteria, to explain how to identify a particular criterion of identity and to determine the logical form in which to express such identifications.

An alternative to the standard endurance/perdurance accounts of persistence has recently been developed: the stage theory (Sider, T. Four-Dimensionalism: an Ontology of Persistence and Time. Oxford: Oxford University Press, 2001; Hawley, K. How Things Persist. Oxford: Oxford University Press, 2001). According to this theory, a persisting object is identical with an instantaneous stage (temporal part). On the basis of Leibniz's Law, I argue that stage theorists either have to deny the alleged identity (i.e., give up their central thesis) or hold (...) that stages are both instantaneous and continuants. I subsequently show that, although stage theory is flexible enough to accommodate the latter claim, the cost for accommodating it is an excessive proliferation of persistence concepts. (shrink)

This paper examines how three central aspects of personhood — the capacities of individuals, their normative status, and the social aspect of being recognized — are related, and how personhood depends on them. The paper defends first of all a ‘basic view’that while actual recognition is among the constitutive elements of full personhood, it is the individual capacities (and not full personhood) which ground the basic moral and normative demands concerning treatment of persons. Actual recognition depends analyti- cally on such (...) pre-existing normative requirements: it is a matter of responsiveness to them. The paper then discusses four challenges. The challenges claim that pace the basic view, the relevant capacities depend on recognition, that recognition seems to have normative rele- vance, and that the basic view cannot as such explain the equality either of persons, or of humans. Responding to these challenges amounts to refining the basic view accordingly. (shrink)

In 1988, Michael Nyman composed the score for Peter Greenaway’s film Drowning by Numbers (or did something that we would ordinarily think of as composing that score). We can think of Nyman’s compositional activity as a “generative performance” and of the sound structure that Nyman indicated (or of some other abstract object that is appropriately related to that sound structure) as the product generated by that performance (ix).1 According to one view, Nyman’s score for Drowning by the Numbers—the musical work—is (...) the product generated by Nyman’s compositional activity (namely, an abstract object) and, more generally, artworks are identified with the products generated by compositional or other creative activities. Let’s call this view The Product Theory. By contrast, according to another view, Nyman’s score for Drowning by Numbers is the generative performance itself (namely, Nyman’s compositional activity) and, more generally, artworks are identified with generative performances themselves. Following David Davies in Art as Performance, let’s call this view The Performance Theory (80). In that book, Davies argues for The Performance Theory and against The Product Theory. (shrink)

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)

Abstract: The natural lottery is a metaphor about the way luck affects the allocation of personal attributes, talents, skills, and defects. Susan Hurley has argued that it is incoherent to regard individual essential properties (IEPs) as a matter of lottery luck. The reason is that a lottery of identity-affecting properties generates the ‘non-identity problem’. For this reason among others she suggests substituting lottery luck with ‘thin luck’, i.e. luck as non-responsibility, which would allow us to coherently regard IEPs as a (...) matter of luck.I argue that we are not not-responsible for our IEPs. Therefore, the coherent range of ‘thin luck’ is not broader than that of lottery luck. Moreover, justice theorists need to be worried about the non-identity problem only to the extent that IEPs affect life prospects and it is far from evident that they do. After addressing some connected aspects of Hurley's analysis, I discuss the type of reasons that justify seeking to expand domain of justice and the ways of doing this, for instance by abandoning lottery luck. I close by suggesting, however, that if Parfit's view of ‘what matters about identity’ is correct, its application to the case of identity-affecting lotteries may prove the expansion of the domain of justice superfluous, as IEPs belong to it as it is.

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)

It seems to be a platitude of common sense that distinct ordinary objects cannot coincide, that they cannot fit into the same place or be composed of the same parts at the same time. The paradoxes of coincidence are instances of a breakdown of this platitude in light of counterexamples that are licensed by innocuous assumptions about particular kinds of ordinary object. Since both the anticoincidence principle and the assumptions driving the counterexamples flow from the folk conception of ordinary objects, (...) the paradoxes threaten this conception with inconsistency. Typical approaches to the paradoxes reject the anticoincidence principle or some portion of the assumptions driving the counterexamples, thereby partially revising our common conception of the world around us. This essay offers a compatibilist solution to the paradoxes that sustains the folk conception of ordinary objects in its entirety. According to this solution, the various cases of distinct coincidents do not clash with the anticoincidence principle since the cases and the principle manifest different yet compatible perspectives on the world.

What is the epistemological role of speech perception in comprehension? More precisely, what is its role in episodes or states of comprehension able to mediate the communication of knowledge? One answer, developed in recent work by Tyler Burge, has it that its role may be limited to triggering mobilizations of the understanding. I argue that, while there is much to be said for such a view, it should not be accepted. I present an alternative account, on which episodes of comprehension (...) are better able to underwrite the interpersonal transmission of knowledge. (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)

This thesis analyses the ontological nature of quantum particles. In it I argue that quantum particles, despite their indistinguishability, are objects in much the same way as classical particles. This similarity provides an important point of continuity between classical and quantum physics. I consider two notions of indistinguishability, that of indiscernibility and permutation symmetry. I argue that neither sort of indistinguishability undermines the identity of quantum particles. I further argue that, when we understand in distinguishability in terms of permutation symmetry, (...) classical particles are just as indistinguishable as quantum particles; for classical physics also possesses permutation symmetry.

What makes an object the same persisting individual over time? Philosophers and psychologists have both grappled with this question, but from different perspectives—philosophers conceptually analyzing the criteria for object persistence, and psychologists exploring the mental mechanisms that lead us to experience the world in terms of persisting objects. It is striking that the same themes populate explorations of persistence in these two very different fields—e.g. the roles of spatiotemporal continuity, persistence through property change, and cohesion violations. Such similarities may reflect (...) an underlying connection, in that psychological mechanisms of object persistence (especially relevant parts of mid-level visual object processing) may serve to underlie the intuitions about persistence that fuel metaphysical theories. This would be a way for cognitive science to join these two disparate fields, helping to explain the possible origins and reliability of some metaphysical intuitions, and perhaps leading to philosophical progress.

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.

Two recurrent arguments levelled against the view that enduring objects survive change are examined within the framework of the B-theory of time: the argument from Leibniz's Law and the argument from Instantiation of Incompatible Properties. Both arguments are shown to be question-begging and hence unsuccessful.

This paper is a modification of Nicola Guarino and Christopher Welty's conception of the subsumption relation. Guarino and Welty require that that whether one property may subsume the other should depend on the modal metaproperties of those properties. I argue that the part of their account that concerns the metaproperty carrying a criterion of identity is essentially flawed. Subsequently, I propose to constrain the subsumption relation not, as Guarino and Welty require, by means of incompatible criteria of absolute identity but (...) by means of incompatible criteria of relative identity. After discussing the benefits of applying relative identity in ontological investigations I provide a formal framework in which to prove a counterpart of the identity criteria constraint. (shrink)

An intensional semantic system for languages containing, in their logical syntax, sortal quantifiers, sortal identities, (second-order) quantifiers over sortals and the necessity operator is constructed. This semantics provides non-standard assignments to predicate expressions, which diverge in kind from the entities assigned to sortal terms by the same semantic system. The nature of the entities assigned to predicate expressions shows, at the same time, that there is an internal semantic connection between those expressions and sortal terms. A formal logical system is (...) formulated that is proved to be absolutely consistent, sound and complete with respect to the intensional semantic system. (shrink)

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.

Inter-species variation in colour perception poses a serious problem for the view that colours are mind-independent properties. Given that colour perception varies so drastically across species, which species perceives colours as they really are? In this paper, I argue that all do. Specifically, I argue that members of different species perceive properties that are determinates of different, mutually compatible, determinables. This is an instance of a general selectionist strategy for dealing with cases of perceptual variation. According to selectionist views, objects (...) simultaneously instantiate a plurality of colours, all of them genuinely mind-independent, and subjects select from amongst this plurality which colours they perceive. I contrast selectionist views with relationalist views that deny the mind-independence of colour, and consider some general objections to this strategy. (shrink)

Closest-continuer or best-candidate accounts of persistence seem deeply unsatisfactory, but it’s hard to say why. The standard criticism is that such accounts violate the ‘only a and b’ rule, but this criticism merely highlights a feature of the accounts without explaining why the feature is unacceptable. Another concern is that such accounts violate some principle about the supervenience of persistence facts upon local or intrinsic facts. But, again, we do not seem to have an independent justification for this supervenience claim. (...) Instead, I argue that closest continuer accounts are committed to unexplained correlations between distinct existences, and that this is their fundamental flaw. We can have independent justification for rejecting such correlations, but what the justification is depends upon much broader issues in ontology. There is no one-size-fits all objection to closest-continuer accounts of persistence. (shrink)

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)

This volume draws connections between Wittgenstein's philosophy and the work of Saul Kripke, especially his Naming and Necessity. Saul Kripke is regarded as one of the foremost representatives of contemporary analytic philosophy. His most important contributions include the strict distinction between metaphysical and epistemological questions, the introduction of the notions of contingent a priori truth and necessary a posteriori truth and original accounts of names, descriptions, identity, necessity and realism. The chapters in this book elucidate the relevant connections between Kripke's (...) work and Wittgenstein, specifically concerning the standard meter, contingent apriori and rule-following. The contributions shed light on how Kripke's philosophical outlook was influenced by Wittgenstein, and how mainstream analytic philosophy and Wittgensteinian philosophy can fruitfully engage with one another. Kripke and Wittgenstein will be of interest to philosophers working on Wittgenstein, Kripke, and the history of analytic philosophy. (shrink)

One of the standard puzzles in ordinary-object metaphysics concerns what happens when an object and one of its undetached parts apparently begin to coincide. I distinguish two versions of this puzzle: the problem of extraordinary undetached parts and the problem of ordinary undetached parts. Then I present a novel phasalist solution to the problem of ordinary undetached parts. My solution is designed to supplement the recently-defended view that ordinary undetached parts exist but extraordinary ones do not.

ObjectiveThis paper explores the interrelation among the concepts of identity, individuality and indiscernibilty, primarily from the standpoint of contemporary western analytic ontology and logic.MethodI review, compare and evaluate the classical and the alternative approaches to identity. In this regard, I focus on the issue whether these purportedly alternative approaches do really provide us with alternative conceptions of identity, or they are considering some other forms of equivalence relations weaker than the relation of identity. Arguments for and against the Principles of (...) Indiscernibility of Identicals and Identity of Indiscernibles are delineated to unravel the connection between identity and indiscernibility. Various attempts to provide the definition of identity in terms of indiscernibility have also been evaluated.FindingsI argue that it is a verbal issue whether we use the term ‘identity’, when analysed in terms of indiscernibility, or ‘congruence’, but the underlying metaphysical issues are not simple. If identity is analysed in terms of indiscernibility, stipulation of one’s philosophical understanding of property and possession of properties in the concerned logic and ontology should be made in clear terms to avoid confusion. But there can also be ontological and logical frameworks where numerical identity and difference are not qualitatively explicable.ConclusionA pluralist stance, at least at the phenomenal level, is proposed to be maintained with regard to the explanation of the phenomenon of identity. This pluralist stance has also been proposed as a plausible metatheoretical framework of metaphysical debates. (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 (or continuity of identity) 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 ourself? How is continuity of self (collective set of our connected experiences in the vessel of time) 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 (the principle of reafference or corollary discharge and the principle of a time theory) 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 theSelf. 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.

Este trabajo examina si la pregunta “¿puede pensar una máquina?” ha sido respondida de manera satisfactoria. La primera sección, justamente, examina el dictum cartesiano según el cual una máquina no puede pensar en principio. La segunda trata sobre una rebelión en contra de Descartes, encabezada por Babbage. A su vez, la tercera describe una segunda rebelión encabezada por Turing. En ambas se examina, primero el lenguaje mentalista/instrumentalista para describir a una máquina programada y segundo, el reemplazo de la pregunta por (...) el Juego de la Imitación. En la cuarta sección sostengo que la evidencia aportada por dicho juego nos devuelve a la pregunta, pese a Turing. Por último, la quinta sección versa sobre cómo la Habitación China de Searle, paradójicamente, apoya el dictum cartesiano, y lo hace porque tal experimento mental se basa en una capacidad mental falible: la introspección. Se concluye que la pregunta acerca de si puede pensar una máquina es derivada de otra pregunta filosófica compleja: la de la naturaleza de lo mental y el problema mente-cuerpo. (shrink)
