Abstract:A number of philosophers of language have proposed that people do not have conceptual access to‘bare particulars’, or attribute‐free individuals (e.g. Wiggins, 1980). Individuals can only be picked out under some sortal, a concept which provides principles of individuation and identity. Many advocates of this view have argued thatobjectis not a genuine sortal concept. I will argue in this paper that a narrow sense of‘object’, namely the concept of any bounded, coherent, three‐dimensional physical object that moves as a whole (Spelke, (...) 1990) is a sortal for both infants and adults. Furthermore,objectmay be the infant's first sortal and more specific sortals such ascupanddogmay be acquired later in the first year of life. I will discuss the implications for infant categorization studies, trying to draw a conceptual distinction between a perceptual category and a sortal, and I will speculate on how a child may construct sortal concepts such ascupanddog.

Much of the debate about identity in recent decades has been about personal identity, and specifically about personal identity over time, but identity generally, and the identity of things of other kinds, have also attracted attention. Various interrelated problems have been at the centre of discussion, but it is fair to say that recent work has focussed particularly on the following areas: the notion of a criterion of identity; the correct analysis of identity over time, and, in particular, the disagreement (...) between advocates of perdurance and advocates of endurance as analyses of identity over time; the notion of identity across possible worlds and the question of its relevance to the correct analysis of de re modal discourse; the notion of contingent identity; the question of whether the identity relation is, or is similar to, the composition relation; and the notion of vague identity. A radical position, advocated by Peter Geach, is that these debates, as usually conducted, are void for lack of a subject matter: the notion of absolute identity they presuppose has no application; there is only relative identity. Another increasingly popular view is the one advocated by Lewis: although the debates make sense they cannot genuinely be debates about identity, since there are no philosophical problems about identity. Identity is an utterly unproblematic notion. What there are, are genuine problems which can be stated using the language of identity. But since these can be restated without the language of identity they are not problems about identity. (For example, it is a puzzle, an aspect of the so-called “problem of personal identity”, whether the same person can have different bodies at different times. But this is just the puzzle whether a person can have different bodies at different times. So since it can be stated without the language of personal “identity”, it is not a problem about identity, but about personhood.) This article provides an overview of the topics indicated above, some assessment of the debates and suggestions for further reading. (shrink)

Unity of science was once a very popular idea among both philosophers and scientists. But it has fallen out of fashion, largely because of its association with reductionism and the challenge from multiple realisation. Pluralism and the disunity of science are the new norm, and higher-level natural kinds and special science laws are considered to have an important role in scientific practice. What kind of reductionism does multiple realisability challenge? What does it take to reduce one phenomenon to another? How (...) do we determine which kinds are natural? What is the ontological basis of unity? In this Element, Tuomas Tahko examines these questions from a contemporary perspective, after a historical overview. The upshot is that there is still value in the idea of a unity of science. We can combine a modest sense of unity with pluralism and give an ontological analysis of unity in terms of natural kind monism. This title is available as Open Access on Cambridge Core. (shrink)

Sortal concepts are at the center of certain logical discussions and have played a significant role in solutions to particular problems in philosophy. Apart from logic and philosophy, the study of sortal concepts has found its place in specific fields of psychology, such as the theory of infant cognitive development and the theory of human perception. In this monograph, different formal logics for sortal concepts and sortal-related logical notions are characterized. Most of these logics are intensional in nature and possess, (...) in addition, a bidimensional character. That is, they simultaneously represent two different logical dimensions. In most cases, the dimensions are those of time and natural necessity, and, in other cases, those of time and epistemic necessity. Another feature of the logics in question concerns second-order quantification over sortal concepts, a logical notion that is also represented in the logics. Some of the logics adopt a constant domain interpretation, others a varying domain interpretation of such quantification. Two of the above bidimensional logics are philosophically grounded on predication sortalism, that is, on the philosophical view that predication necessarily requires sortal concepts. Another bidimensional logic constitutes a logic for complex sortal predicates. These three sorts of logics are among the important novelties of this work since logics with similar features have not been developed up to now, and they might be instrumental for the solution of philosophically significant problems regarding sortal predicates. The book assumes a modern variant of conceptualism as a philosophical background. For this reason, the approach to sortal predicates is in terms of sortal concepts. Concepts, in general, are here understood as intersubjective realizable cognitive capacities. The proper features of sortal concepts are determined by an analysis of the main features of sortal predicates. Posterior to this analysis, the sortal-related logical notions represented in the above logics are discussed. There is also a discussion on the extent to which the set-theoretic formal semantic systems of the book capture different aspects of the conceptualist approach to sortals. These different semantic frameworks are also related to realist and nominalist approaches to sortal predicates, and possible modifications to them are considered that might represent those alternative approaches.

This book develops a novel generalization of possible world semantics, called ‘world line semantics’, which recognizes worlds and links between world-bound objects (world lines) as mutually independent aspects of modal semantics. Addressing a wide range of questions vital for contemporary debates in logic and philosophy of language and offering new tools for theoretical linguistics and knowledge representation, the book proposes a radically new paradigm in modal semantics. This framework is motivated philosophically, viewing a structure of world lines as a precondition (...) of modal talk. The author provides a uniform analysis of quantification over individuals (physical objects) and objects of thought (intentional objects). The semantic account of what it means to speak of intentional objects throws new light on accounts of intentionality and singular thought in the philosophy of mind and offers novel insights into the semantics of intensional transitive verbs.

I will discuss the implications for infant categorization studies, trying to draw a conceptual distinction between a perceptual category and a sortal, and I will speculate on how a child may construct sortal concepts such as cup and dog.

We tend to talk about (refer to, quantify over) parts in the same way in which we talk about whole objects. Yet a part is not something to be included in an inventory of the world over and above the whole to which it belongs, and a whole is not something to be included in the inventory over and above its constituent parts. This paper is an attempt to clarify a way of dealing with this tension which may be labeled (...) the Minimalist View: An element in the field of a part-whole relation is to be included in an inventory of the world if and only if it does not overlap any distinct element that is itself included in the inventory.

As it turns out, a clarification of this view involves both a defense of mereological extensionality and an account of the topological distinction between detached and undetached parts. (shrink)

Ontological dependence is a relation—or, more accurately, a family of relations—between entities or beings. For there are various ways in which one being may be said to depend upon one or more other beings, in a sense of “depend” that is distinctly metaphysical in character and that may be contrasted, thus, with various causal senses of this word. More specifically, a being may be said to depend, in such a sense, upon one or more other beings for its existence or (...) for its identity. Some varieties of ontological dependence may be analyzed in modal terms—that is, in terms of distinctly metaphysical notions of possibility and necessity—while others seem to demand an analysis in terms of the notion of essence. The latter varieties of ontological dependence may accordingly be called species of essential dependence. Notions of ontological dependence are frequently called upon by metaphysicians in their proposed analyses of other metaphysically important notions, such as the notion of substance. (shrink)

Advocates of sortal essentialism have argued that concepts like “thing” or “object” lack the unambiguous individuative criteria necessary to play the role of genuine sortals in reference. Instead, they function as “dummy sortals” which are placeholders or incomplete designations. In disqualifying apparent placeholder sortals, however, these philosophers have posed insuperable problems for accounts of childhood conceptual development. I argue that recent evidence in psychology demonstrates that children do possess simple or basic sortals of physical objects or things. I contend that (...) these concepts provide the genuine individuative criteria necessary for reference. As a consequence, sortalism can be made compatible with the developmental facts of conceptual development. (shrink)

In 'Physics' I.7, Aristotle claims that plants and animals are generated from sperma. Since most understood sperma to be an ovum, this claim threatens to undermine the standard view that, for Aristotle, the matter natural beings are generated from persists through their generation. By focusing on Aristotle’s discussion of sperma in the first book of the 'Generation of Animals', I show that, for Aristotle, sperma in the female is surplus blood collected in the uterus and not an ovum. I subsequently (...) argue that, for Aristotle, this blood does persist through the production of the fetus. (shrink)

The ante rem structuralist holds that places in ante rem structures are objects with determinate identity conditions, but he cannot justify this view by providing places with criteria of identity. The latest response to this problem holds that no criteria of identity are required because mathematical practice presupposes a primitive identity relation. This paper criticizes this appeal to mathematical practice. Ante rem structuralism interprets mathematics within the theory of universals, holding that mathematical objects are places in universals. The identity problem (...) should be read as challenging this claim about universals. However, what mathematical practice presupposes is only relevant to what is true according to the theory of universals, if one takes it for granted such a theory offers the best interpretation of mathematics. In the current context, taking this for granted begs the question. Therefore, the appeal to mathematical practice in response to the identity problem is illegitimate. (shrink)

I begin by criticizing an elaboration of an argument in this journal due to Hawley , who argued that, where Leibniz’s Principle of the Identity of Indiscernibles faces counterexamples, invoking relations to save PII fails. I argue that insufficient attention has been paid to a particular distinction. I proceed by demonstrating that in most putative counterexamples to PII , the so-called Discerning Defence trumps the Summing Defence of PII. The general kind of objects that do the discerning in all cases (...) form a category that has received little if any attention in metaphysics. This category of objects lies between indiscernibles and individuals and is called relationals: objects that can be discerned by means of relations only and not by properties. Remarkably, relationals turn out to populate the universe. (shrink)

Puzzles about persistence and change through time, i.e., about identity across time, have foundered on confusion about what it is for ‘two things’ to be have ‘the same thing’ at a time. This is most directly seen in the dispute over whether material objects can occupy exactly the same place at the same time. This paper defends the possibility of such coincidence against several arguments to the contrary. Distinguishing a temporally relative from an absolute sense of ‘the same’, we see (...) that the intuition, ‘this is only one thing’, and the dictum, ‘two things cannot occupy the same place at the same time’, are individuating things at a time rather than absolutely and are therefore compatible with coincidence. Several other objections philosophers have raised ride on this same ambiguity. Burke, originating what has become the most popular objection to coincidence, argues that if coincidence is possible there would be no explanation of how objects that are qualitatively the same at a time could belong to different sorts. But we can explain an object’s sort by appealing to its properties at other times. Burke’s argument to the contrary equivocates on different notions of ‘cross-time identity’ and ‘the statue’. From a largely negative series of arguments emerges a positive picture of what it means to say multiple things coincide and of why an object’s historical properties explain its sort rather than vice versa – in short, of how coincidence is possible.

Many philosophers believe that the criteria of identity over time for ordinary objects entail that such objects are permanent members of certain sortal kinds. The sortal kinds in question have come to be known as substance sortal kinds. But in this article, I defend a criterion of identity that is suited to phasalism, the view that alleged substance sortals are in fact phase sortals. The criterion I defend is a sortal‐weighted version of a change‐minimizing criterion first discussed by Eli Hirsch. (...) I present this criterion and then argue that it withstands attempts to show that it is inferior to non‐phasalist rivals. (shrink)

This paper argues that if persons last over time by “enduring”, then no analysis or reduction of personal identity over time in tenus of any sort of psychological continuity can be correct. In other words, any analysis of personal identity over time in tenus of psychological continuity entails that persons are four-dimensional and have temporal parts. The paper then shows that if we abandon psychological analyses of personal identity---as we must if persons endure---Parfit’s argument for the claim that identity does (...) not matter in survival is easily undenuined. The paper then suggests that this offers support for the claim that persons endure. Along the way the paper tries to clarify the contrast between the doctrine that persons endure and its rival, four-dimensionalism. (shrink)

The aim of this note is to discuss the general form and role of identity criteria. We have taken two readings into consideration which express two different functions of identity criteria. The first expresses the epistemic function whilst the second deals with the ontological function. We argue that there are several problems related to the specification of both these functions. As a consequence, we conclude that identity criteria are not necessary to provide ontological legitimacy.

How could the self be a substance? There are various ways in which it could be, some familiar from the history of philosophy. I shall be rejecting these more familiar substantivalist approaches, but also the non-substantival theories traditionally opposed to them. I believe that the self is indeed a substance—in fact, that it is a simple or noncomposite substance—and, perhaps more remarkably still, that selves are, in a sense, self-creating substances. Of course, if one thinks of the notion of substance (...) as an outmoded relic of prescientific metaphysics—as the notion of some kind of basic and perhaps ineffablestuff—then the suggestion that the self (or indeed anything) is a substance may appear derisory. Even what we ordinarilycall‘stuffs’—gold and water and butter and the like—are, it seems, more properly conceived of as aggregates of molecules or atoms, while the latter are not appropriately to be thought of as being ‘made’ of any kind of ‘stuff’ at all. But this only goes to show that we need to think in terms of a more sophisticated notion of substance—one which may ultimately be traced back to Aristotle's conception of a ‘primary substance’ in theCategories, and whose heir in modern times is W. E. Johnson's notion of the ‘continuant’. It is the notion, that is, of a concrete individual capable of persisting identically through qualitative change, a subject of alterable predicates that is not itself predicable of any further subject.

It has long been debated whether objects are ‘sortally’ individuated. This paper begins by clarifying some of the key terms in play—in particular, ‘sortal’, ‘individuation’, and ‘object’. The term ‘individuation’ is taken to have both a cognitive and a metaphysical sense, in the former denoting the singling out of an object in thought and in the latter a determination relation between entities. ‘Sortalism’ is defined as the doctrine that only as falling under some specific sortal concept can an object be (...) successfully singled out in thought. It is argued that such a view is too strong, but that a weaker one, ‘categorialism’, can be defended, this implying that a thinker cannot successfully single out an object in thought without having at least an implicit grasp of the criterion of identity that the object satisfies. (shrink)

Non-Cartesian substance dualism maintains that persons or selves are distinct from their organic physical bodies and any parts of those bodies. It regards persons as ‘substances’ in their own right, but does not maintain that persons are necessarily separable from their bodies, in the sense of being capable of disembodied existence. In this paper, it is urged that NCSD is better equipped than either Cartesian dualism or standard forms of physicalism to explain the possibility of mental causation. A model of (...) mental causation adopting the NCSD perspective is proposed which, it is argued, is consistent with all that is currently known about the operations of the human central nervous system, including the brain. Physicalism, by contrast, seems ill-equipped to explain the distinctively intentional or teleological character of mental causation, because it effectively reduces all such causation to ‘blind’ physical causation at a neurological level.

I defend the view that our ontology divides into categories, each with its own canonical way of identifying and distinguishing the objects it encompasses. For instance, I argue that natural numbers are identified and distinguished by their positions in the number sequence, and physical bodies, by facts having to do with spatiotemporal continuity. I also argue that objects belonging to different categories are ipso facto distinct. My arguments are based on an analysis of reference, which ascribes to reference a richer (...) structure than it is normally taken to have. (shrink)

Are there sensory states that, unlike mere sensory registrations, require an explanatory framework that goes beyond biology? Based on a reconstruction of Kant’s a priori, transcendental psychology, contemporary Kantians answer this question in the positive but dramatically limit the scope of psychology. In contrast, naturalistically oriented deflationists answer it in the negative, thereby not giving psychology any explanatory role whatsoever. In his recent monumental book Origins of Objectivity, Burge argues against both of these approaches and seeks to develop an intermediate (...) approach between them. This he does by embedding Kantian transcendental psychology in contemporary science of perception, thereby naturalizing the former and considerably broadening the scope of psychology. In this paper I critically examine Burge’s naturalized Kantianism, thereby defending transcendental Kantianism. To this end, I first outline Kantian transcendental psychology of perception, highlighting the features that distinguish it from biology. I then show how Burge naturalizes this psychology by embedding its most fundamental notions in contemporary science of perception. Based on all this, I conclude the paper by arguing for two closely related claims. First, that transformed into empirical psychology, Kantian transcendental psychology loses the features that distinguish it from biology. Second, that genuine perception starts at the high cognitive level for which transcendental psychology accounts and not at the rather low or elementary level on which Burge focuses. (shrink)

Sortal terms, such as table or horse, are count nouns (akin to a basic-level terms). According to some theories, the meaning of sortals provides conditions for telling objects apart (individuating objects, e.g., telling one table from a second) and for identifying objects over time (e.g., determining that a particular horse at one time is the same horse at another). A number of psychologists have proposed that sortal concepts likewise provide psychologically real conditions for individuating and identifying things. However, this paper (...) reports five experiments that cast doubt on these psychological claims. Experiments 1-3 suggest that sortal concepts do not determine when an object ceases to exist and therefore do not decide when the object can no longer be identical to a later one. Experiments 4-5 similarly suggest that sortal concepts do not provide determinate conditions for individuating objects. For example, they do not always decide whether a room contains one table or two. All five experiments feature ordinary objects undergoing ordinary changes. (shrink)

According to the sortal conception of the universe of individuals every individual falls under a highest sortal, or category. It is argued here that on this conception the identity relation is defined between individuals a and b if and only if a and b fall under a common category. Identity must therefore be regarded as a relation of the form \, with three arguments x, y, and Z, where Z ranges over categories, and where the range of x and y (...) depends on the value of Z. An identity relation of this kind can be made good sense of in Martin-Löf’s type theory. But identity so construed requires a reformulation of Hume’s Principle that makes this principle unfit for explaining the sortal concept of cardinal number. The Neo-Logicist can therefore not appeal to the sortal conception in tackling the Julius Caesar problem, as proposed by Hale and Wright. (shrink)

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. (shrink)

In this paper, a general perspective on criteria of identity of kinds of objects is developed. The question of the admissibility of impredicative or circular identity criteria is investigated in the light of the view that is articulated. It is argued that in and of itself impredicativity does not constitute sufficient grounds for rejecting a putative identity criterion. The view that is presented is applied to Davidson’s criterion of identity for events and to the structuralist criterion of identity of places (...) in a structure. (shrink)

I argue that, despite van Inwagen’s pessimism about the task, it is worth looking for answers to his General Composition Question. Such answers or ‘principles of composition’ tell us about the relationship between an object and its parts. I compare principles of composition with criteria of identity, arguing that, just as different sorts of thing satisfy different criteria of identity, they may satisfy different principles of composition. Variety in criteria of identity is not taken to reflect ontological variety in the (...) identity relation; I discuss whether variety in principles of composition should be taken to reflect ontological variety in the composition relation.

In the debate on personal identity, different criteria of identity are proposed and defended. The criteria of identity have usually been taken to state the necessary and sufficient conditions of identity and are interpreted as providing truth conditions for relevant identity statements. The Simple View of personal identity is the thesis that there are no noncircular and informative metaphysical criteria of identity for persons. The paper intends to first deliver a precise and general formulation of the Simple View, and, second, (...) to present the various arguments in favour of the doctrine in question. It argues that there are no other facts of the matter than identity itself which could serve as the truth-conditions of identity statements. The considerations presented in the paper lead to the conclusion that, although the Simple View is faced with many theoretical difficulties, it is still a lively intellectual position in the debate on personal identity. (shrink)

According to one popular criterion of property identity, where X and Y are properties, X is identical with Y if and only if X and Y bestow the same conditional powers on their bearers. In this paper, I argue that this causal criterion of property identity is unsatisfactory, because it fails to provide a sufficient condition for the identification of properties. My argument for this claim is based on the observation that the summing of properties does not entail the summing (...) of the conditional powers that they bestow on an object, but, rather, in some cases their subtraction. If so, the following causal structure seems possible: There are two properties, A and B. Each bestows a different set of conditional powers on its bearer, but the conjunctive property A-and-B bestows exactly the same set of conditional powers as either A or B. If this causal structure is possible, then it creates a serious problem for the causal criterion of property identity. (shrink)

We shall distinguish between sortal predication and standard predication. The former kind of predication necessarily involves sortal concepts but the latter, as it is customarily viewed, does not. It is generally thought that the only essential occurrence of a concept in a standard predication is the concept being predicated. In this paper, we shall put forward an alternative view. We shall propose to understand standard predication as a cognitive act essentially requiring sortal concepts. We shall call this view conceptual predication (...) sortalism and ground it on the basis of epistemic-semantic reasons. Concepts are understood as intersubjectively realizable capacities or abilities that fulfill particular cognitive roles, such as those of classification, categorization, individuation, and referring.

Příspěvek hodlá zkoumat některé filozofické předpoklady a důsledky tzv. sortální identity. Téma sortálů si vysloužilo pozornost filozofů od 60. let především v souvislosti s knihou P. Geache Reference and Generality. Témata identity, její případné závislosti na určitých predikátech a zejména otázka kritérií identity se následně stala předmětem intenzivní filozofické debaty. V této souvislosti budou nastíněna různá pojetí sortálů. Filozofický význam sortálů spočívá především v otázce individuace a (re)identifikace objektů. Mezi sortálními teoretiky se především rozhořela debata, zda jsou s individui některé (...) sortály spojeny nutně, tj. jestli platí, že pokud individuum spadá pod nějaký sortál, pak nemůže spadat pod jiný. Pozitivní odpověď zakládá klasický aristotelský esencialismus, k záporné odpovědi směřují antiesencialisté. V sortální logice se navíc poměrně často buduje hierarchie sortálů, kdy sortály mohou (příp. musí) být ve vztahu podřazenosti k jinému sortálu a lze dokonce uvažovat o případném nejvyšším sortálu jakožto sortálu, který již není podřízen žádnému jinému. Zde se přímo nabízí souvislost s aristotelskou hierarchií kategorií, analogie s touto naukou budou předmětem závěrečného srovnání. (shrink)

Token physicalism is often viewed as a modest and unproblematic physicalist commitment, as contrasted with type physicalism. This paper argues that the prevalence of functional individuation in biology creates serious problems for token physicalism, because the latter requires that biological entities can be individuated physically and without reference to biological functioning. After characterizing the main philosophical roles for token physicalism, I describe the distinctive uses of functional individuation in models of biological processes. I then introduce some requirements on token identity (...) claims that arise from a position on individuation and identity known as sortalism. An examination of biological examples shows that these sortalist requirements cannot be plausibly met due to differences between individuation by functional biological criteria and by physical criteria. Even without assuming sortalism, token physicalism faces the more basic problem of excluding functionally irrelevant detail from the individuation of biological tokens. I close by suggesting that the philosophical roles for token identity are better fulfilled by a notion of token composition, which promotes a hierarchical picture of individuality. (shrink)

Motivated by avoiding a difficulty confronting the usual formulations of identity criteria, Fine has proposed and developed a generic account of grounding. In this paper, I examine two versions of the account. I argue that both proposals fail, as it is difficult to see how the strategy of ‘going generic’ can really solve the problem. I conclude that the idea of generic grounding is mysterious and unmotivated.

The concept of nature in Western thought has been informed by the assumption of a categorical distinction between natural and artificial entities, which goes back to John Stuart Mill or even Aristotle. Such a way of articulating the natural/artificial distinction has proven unfit for conservation purposes mainly because of the extent and the pervasiveness of human activities that would leave no nature left to be conserved, and alternative views have been advanced. In this contribution, after arguing for the importance of (...) the concept of naturalness as a guide for conservation, I will try to provide an account of the natural/artificial distinction suited to contemporary conservation framing. Focusing on a particular kind of objects that I suggest to name “environmental objects”, I propose and defend the view of “naturalness as independence” according to which the more or less an environmental object's identity conditions and survival depend on human intervention, the more or less that object is artificial or natural, respectively. According to this view, conserving environmental objects will equate to maintaining or improving their naturalness or even originating artificial objects that may become new natural objects. This view has the advantage, on the one hand, of providing a rationale for a distinction which is not only part of how people think, but also pervasive in conservation practices and policies and, on the other hand, of accounting for the global pervasiveness of human intervention in the so-called natural world.

Are identity criteria grounding principles? A prima facie answer to this question is positive. Specifically, two-level identity criteria can be taken as principles related to issues of identity among objects of a given kind compared with objects of a more basic kind. Moreover, they are grounding metaphysical principles of some objects with regard to others. In the first part of the paper we criticise this prima facie natural reading of identity criteria. This result does not mean that identity criteria could (...) not be taken as grounding principles. In the second part, we propose some basic steps towards a conceptual reading of grounding. Such a way of understanding it goes along with an epistemic reading of identity criteria. (shrink)

A popular stance amongst philosophers is one according to which, in Lewis’ words, “identity is utterly simple and unproblematic”. Building from Lewis’ famous passage on the matter, we reconstruct, and then criticize, an argument to the conclusion that identities cannot be grounded. With the help of relatively uncontroversial assumption concerning identity facts, we show that not all identities are equi-fundamental, and, on the contrary, some appear to be provided potential grounding bases using two-level identity criteria. Further potential grounding bases for (...) identities are presented. Identity might be utterly simple and unproblematic, but this is not sufficient to conclude that identities are ungrounded, or fundamental. (shrink)

Can an identity be the proper subject of an explanation? A popular stance, albeit not one often argued for, gives a negative answer to this question. Building from a contentious passage from Jaegwon Kim in this direction, we reconstruct an argument to the conclusion that identities, to the extent in which they are necessary, cannot be explained. The notion of contrastive explanation, characterized as difference-seeking, will be crucial for this argument; however, we will eventually find the argument to be unsatisfactory. (...) On the contrary, the discussion provides enough resource to sketch a very simple framework for a non-causal contrastive explanation of identities. Many instances will be provided, with different varieties of explanans, ultimately suggesting that certain entailment or biconditional principles involving identities (first and foremost, so-called two-level identity criteria) may indeed be taken to have an inherent explanatory value.

The question of how properties are individuated is extremely important. Consider the following proposals. To be in pain is to be in a certain neurological state. To be red is to appear red to normal observers in standard conditions. To be obligatory is to maximize the good. Each makes a claim of property identity. Each is a substantive metaphysical thesis of wide interest. None can be studied with due scrutiny in the absence of a general account of property identity. Here, (...) I will survey existing accounts and suggest a new account in terms of grounding that has some advantages over the other candidates. (shrink)

How have online communities affected the ways their users construct, view, and define their identity? In this paper, we will approach this issue by considering two philosophical sets of problems related to personal identity: the “Characterization Question” and the “Self-Other Relations Question.” Since these queries have traditionally brought out different problems around the concept of identity, here we aim at rethinking them in the framework of online communities. To do so, we will adopt an externalist and cognitive point of view (...) on online communities, describing them as virtual cognitive niches. We will evaluate and agree with the Attachment Theory of Identity, arguing that there is continuity between offline and online identity and that usually the latter contributes to the alteration of the former. Finally, we will discuss ways users can enact self-reflection on online frameworks, considering the impact of the Filter Bubble and the condition of Bad Faith. (shrink)

2020 update of the entry "Properties".

In this paper we reconstruct an argument, based on the observations of David Lewis and Jaegwon Kim, according to which, given that identities are necessary, they cannot be grounded; and given that they cannot be grounded, they cannot be explained either. We argue against two key premises of this argument. Furthermore, we present two counterexamples, in the form of two alleged sets of cases of explanation of identities. This argument against the explanation of identities is instrumental for a wider discussion (...) about the nature of explanation itself, in relation with other notions of recent philosophical interest such as grounding.
