How might we change ourselves without ending our existence? What could we become, if we had access to an advanced form of bioengineering that allowed us dramatically to alter our genome? Could we remain in existence after ceasing to be alive? What is it to be human? Might we still exist after changing ourselves into something that is not human? What is the significance of human extinction? Steven Luper addresses these questions and more in this thought-provoking study. He defends an (...) animalist account, which says that we are organisms, but claims that we are also material objects. His book goes to the heart of the most complex questions about what we are and what we might become. Using case studies from the life sciences as well as thought experiments, Luper develops a new way of thinking about the nature of life and death, and whether and how human extinction matters.

This essay explores Edmund Husserl's significance for contemporary truth theory. Focusing on his Logical Investigations, it argues that early Husserl's conception of truth unsettles a common polarity between epistemic and nonepistemic approaches. Unlike contemporary epistemic conceptions of truth, he gives full weight to “truth makers” that have their own being: objective identity, perceptible objects, and states of affairs. Yet, unlike contemporary nonepistemic conceptions, he also insists on the intentional givenness of such truth makers and on the complexity of the (...) experiences within which propositional truth claims arise. To develop this argument, the essay explains how early Husserl's conception of truth builds on his phenomenology of intentional experience and knowledge. By emphasizing an objective identity between what is signitively meant and intuitively given, Husserl's approach provides a way to resituate propositional truth within a broader and more dynamic conception of truth.

It has been found that children appreciate the limited substitutability of co-referential terms in opaque contexts a year or two after they pass false belief tasks (e.g. Apperly and Robinson, 1998, 2001, 2003). This paper aims to explain this delay. Three- to six-year-old children were tested with stories where a protagonist was either only partially informed or had a false belief about a particular object. Only a few children had problems predicting the protagonist’s action based on his partial knowledge, (...) when he was only partially informed about a property of the desired object (e.g. he knew that it was a Lego® block, but not that it was a red Lego® block). But many had problems making the correct action prediction when he was only partially informed about dual identities (e.g. he knew it was a dog, but not that it was also an eraser). About as many children made an incorrect action prediction for partial knowledge problems involving dual identity as answered higher-order belief questions incorrectly. In contrast many more children answered first-order false belief questions correctly, as many as correct action predictions when the protagonist was partially informed about a property of an object. The results support the claim that children have a specific problem with dual identity, rather than a broader problem representing partial knowledge. (shrink)

What is the conscious mind? What is experience? In 1968, David Armstrong asked “What is a man?” and replied that a man is “a certain sort of material object”. This book starts from his question but proceeds along a different path. The traditional mind-brain identity theory is set aside, and a mind-object identity theory is proposed in its place: to be conscious of an object is simply to be made of that object. Consciousness is (...) physical but not neural. This groundbreaking hypothesis is supported by recent empirical findings in both perception and neuroscience, and is herein tested against a series of objections of both conceptual and empirical nature: the traditional mind-brain identity arguments from illusion, hallucinations, dreams, and mental imagery. The theory is then compared with existing externalist approaches including disjunctivism, realism, embodied cognition, enactivism, and the extended mind. Can experience and objects be one and the same? (shrink)

In this paper, I discuss a view of de re thoughts that can be naturally endorsed in the wake of Russell's account. This is the view that a thought is about the very thing (res) rather than a mere characterization of it if and only if it is constitutively tied, if not to the existence, at least to the identity of its object and the thinker knows which/who the object of his/her thought is. Faced with the challenge (...) of accommodating far from uncommon cases of mistaken identity or substantial confusion on the part of the subject, I argue that the integrity of the view can be preserved and that the restrictions set on its truth by the advocates of the two-component picture and the anti-essentialists can be lifted.

The task of tracking a small number (about four or five) visual targets within a larger set of identical items, each of which moves randomly and independently, has been used extensively to study object-based attention. Analysis of this multiple object tracking (MOT) task shows that it logically entails solving the correspondence problem for each target over time, and thus that the individuality of each of the targets must be tracked. This suggests that when successfully tracking objects, observers must (...) also keep track of them as unique individuals. Yet in the present studies we show that observers are poor at recalling the identity of successfully tracked objects (as specified by a unique identifier associated with each target, such as a number or starting location). Studies also show that the identity of targets tends to be lost when they come close together and that this tendency is greater between pairs of targets than between targets and nontargets. The significance of this finding in relation to the multiple object tracking paradigm is discussed. (shrink)

: Traditional mind-body identity theories maintain that consciousness is identical with neural activity. Consider an alternative identity theory – namely, a mind-object identity theory of consciousness. I suggest to take into consideration whether one’s consciousness might be identical with the external object. The hypothesis is that, when I perceive a yellow banana, the thing that is one and the same with my consciousness of the yellow banana is the very yellow banana one can grab and (...) eat, rather than the neural processes triggered by the banana. The bottom line is that one’s conscious experience of an object is the object one experiences. First, I outline the main hypothesis and the relation between mind, body, and object. Eventually, I address a series of traditional obstacles such as hallucinations, illusions, and commonsensical assumptions. Keywords: Identity Theory; Mind/Body Problem; Consciousness; Hallucinations; Illusions Le esperienze sono oggetti. Verso una teoria dell’identità della mente in quanto oggetto Riassunto: Le teorie dell’identità tra mente e corpo di tipo tradizionale hanno affermato una relazione di identità tra coscienza e attività neurale. Si consideri una teoria dell’identità di carattere alternativo – propriamente una teoria dell’identità che intenda la coscienza come un oggetto. Suggerisco di considerare la possibilità che la coscienza di qualcuno possa essere trattata come identica a un oggetto del mondo esterno. Sulla base di questa ipotesi, quando percepisco una banana gialla, ciò che coincide con la mia coscienza della banana gialla è proprio la banana gialla che si può prendere e mangiare, piuttosto che il processo neurale innescato dalla banana. In definitiva l’esperienza cosciente di un oggetto che ciascuno ha è l’oggetto che si esperisce. In una prima parte, procederò con il delineare l’ipotesi principale e la relazione tra mente, corpo e oggetto. Successivamente cercherò di risolvere alcuni problemi di tipo tradizionale, quali le allucinazioni, le illusioni e gli assunti di senso comune. Parole chiave: Teoria dell’identità; Problema mente/corpo; Coscienza; Allucinazioni; Illusioni. (shrink)

By investigating one of the major inconsistencies that Hume's parallel treatment of the identity of persons and objects issues, this essay offers an unconventional account of what it needs to avoid a dualist picture of mind and world. It will be argued that much hinges on the question of whether or not one is willing to allow the principally unperceivable to enter into one's concept of reality. Hume, as will be shown, rejects this approach: he denies that we have (...) reason to think that there are substances that divide the world into two separate realms. The strategic value of this move is that it enables us to think of minds in terms similar to those underlying our conception of physical objects without urging us to engage in reductionist or eliminativist projects.

Object identity, the apprehension that two glimpses refer to the same object, is offered as an example of combining generality, mathematics, and evolution. We argue that it applies to glimpses in time (apparent motion), modality (ventriloquism), and space (Gestalt grouping); that it has a mathematically elegant solution of nested geometries (Euclidean, Similarity, Affine, Projective, Topology); and that it is evolutionarily sound despite our Euclidean world.

Descartes holds that ideas have or contain _objective reality_ of their objects, so that the idea of the sun is the sun itself existing in the intellect. In this paper, I examine this obscure thesis which grounds the disagreement about Descartes’ commitment to direct or indirect realism. I suggest that, importantly, both readings are correct to a certain extent. I argue that the view of objective reality Descartes develops bears the earmarks of both direct and indirect realist views but must (...) be classified as a third alternative combining some central features of both. I elaborate first on the direct realist interpretations of Descartes’ objective reality and explain their most significant shortcomings. My interpretation of objective identity comes in the form of attributing to Descartes a view about identity and persistence of objects known as _sortalism_. I argue that Descartes’ objective identity turns out to be much like the Aristotelian view of _formal identity_, yet without the forms. By way of discussing the case of Theseus’ ship, I point out how Cartesian sortalism, contrary to other versions of sortalism, allows us to analyze the puzzle as a tension between two distinct yet independently legitimate criteria of identity. It is this sortalist insight that helps to render Descartes’ account of objective identity consistent. This point also grounds my argument that we need not consider direct and indirect realism as logical complements, contrary to the received wisdom. (shrink)

considered an objection that he says he thought was first put to him by Max Black. He says.

'Object' and 'criterion of identity' are philosophical terms of art whose application lies at a considerable theoretical remove from the surface phenomena of everyday linguistic usage. This partly explains their highly controversial status, for their point of application lies precisely where the concerns of linguists and philosophers of language merge with those of metaphysicians. This chapter explains the possession of determinate identity‐conditions. It argues that the distinction between 'abstract' and 'concrete' objects is itself a highly controversial one, (...) and although it has indeed been argued that this distinction turns ultimately upon differences between the criteria of identity governing objects of these two broad categories. It examines the role which criteria of identity play in our talk about objects of the least controversial varieties. The chapter concerns the problem of identity over time and the paradoxes to which identity criteria often appear to give rise when time is brought into the picture. (shrink)

Owned objects are typically viewed as non-fungible-they cannot be freely interchanged. We report three experiments (total N=312) demonstrating this intuition in preschool-aged children. In Experiment 1, children considered an agent who takes one of two identical objects and leaves the other for a peer. Children viewed this as acceptable when the agent took his own item, but not when he took his peer's item. In Experiment 2, children considered scenarios where one agent took property from another. Children said the victim (...) could take back her own property from the perpetrator, but that she could not take an identical object belonging to the perpetrator. Finally, in Experiment 3A and 3B, children considered scenarios where a teacher could give a child either of two objects to play with-an object that the child had recently played with, or another object that looked the same. Children were more likely to say that the teacher should give the object recently played with when it belonged to the child, compared with when it belonged to the teacher. These findings are informative about the basis of judgments that property is non-fungible, and about young children's representation of ownership rights. They show that children's representation of ownership rights is not limited to principles protecting owners from being deprived. Our findings instead suggest that ownership rights are viewed as pertaining to individual objects. (shrink)

In the first twelve chapters of this book, I am concerned with the Fregean notion of an object (the reference of a proper name) and its connection with the notion of identity. The rest of the book is devoted to a discussion of the problem of personal identity.

According to classical physics _particles_ are basic building blocks of the world. These classical particles are distinguishable objects, individuated by unique combinations of physical properties. By contrast, in quantum mechanics the received view is that particles of the same kind (“identical particles”) are physically indistinguishable from each other and lack identity. This doctrine rests on the quantum mechanical (anti)symmetrization postulates together with the “factorist” assumption that each single particle is represented in exactly one factor space of the tensor product (...) Hilbert space of a many-particle system. Even though standard in theoretical physics and the philosophy of physics, the assumption of factorism and the ensuing indistinguishability of particles are problematic. Particle indistinguishability is irreconcilable with the everyday meaning of “particle”, and also with how this term is used in the practice of physics. Moreover, it is a consequence of the standard view that identical quantum particles remain indistinguishable even in the classical limit, which makes a smooth transition to the classical particle concept impossible. Lubberdink (1998; 2009) and Dieks and Lubberdink (2011) have proposed an alternative conception of quantum particles that does not rely on factorism and avoids these difficulties. We further explain and discuss this alternative framework here. One of its key consequences is that particles in quantum theory are not fundamental but _emergent_; another that once they have emerged, quantum particles are always physically distinguishable and thus possess a physically grounded identity.

Contrary to Block's assertion, “identity-crowding” does not provide an interesting instance of object-seeing without object-attention. The successful judgments and unusual phenomenology of identity-crowding are better explained by unconscious perception and non-perceptual phenomenology associated with cognitive states. In identity-crowding, as in other cases of crowding, subjects see jumbled textures and cannot individuate the items contributing to those textures in the absence of attention. Block presents an attenuated sense in which identity-crowded items are seen, but this (...) is irrelevant to the debate about phenomenal experience of an object in the absence of object-attention. Finally, even unconscious object perception in identity-crowding likely involves an attention-like selective process. (shrink)

Weatherson argues that whoever accepts classical logic, standard mereology and the difference between vague objects and any others, should conclude that there are no vague objects. Barnes and Williams claim that a supporter of vague objects who accepts classical logic and standard mereology should recognize that the existence of vague objects implies indeterminate identity. Even though it is not clearly stated, they all seem to be committed to the assumption that reality is ultimately constituted by mereological atoms. This assumption (...) is not granted by standard mereology which instead remains silent on whether reality is atomic or gunky; therefore, I contend that whoever maintains classical logic, standard mereology and the difference between vague objects and any others, is not forced to conclude with Weatherson that there are no vague objects; nor is she compelled to revise her point of view according to Barnes and Williams’s proposal and to accept that the existence of vague objects implies indeterminate identity.

Identity is a transitive relation, according to all standard accounts. Necessarily, if x = y and y = z, then x = z. However, people sometimes say that two objects, x and z, are the same as a third, y, even when x and z have different properties (thus, x = y and y = z, but x ≠ z). In the present experiments, participants read stories about an iceberg that breaks into two icebergs, one to the east and (...) the other to the west. Many participants (32–54%, in baseline conditions across experiments) decided that both successors were the original iceberg, despite the different spatial locations of the successors. Experiment 1 shows that this tendency is not due to participants failing to understand both to mean both are simultaneously the original. Similarly, Experiment 2 demonstrates that the tendency is not solely due to their interpreting the question to be about properties of the icebergs rather than about the icebergs themselves. Experiments 3 and 4 suggest, instead, that participants may understand Which is the original? to mean Which, in its own right, is entitled to be the original? Emphasizing entitlement increases the number of seemingly intransitive responses, whereas emphasizing the formal properties of identity decreases them. (shrink)

My belief that Socrates was wise, and your belief that Socrates was mortal can be said to have a common focus, insofar as both these thoughts are about Socrates. In Peter Geach’s terminology, the objects of our beliefs bear the feature of intentional identity, because our beliefs share the same putative target. But what if it turned out that Socrates never existed? Can a pair of thoughts share a common focus if the object both thoughts are about, does (...) not actually, really exist? Object-centric accounts of intentionality which explain the aboutness or directedness of thought in terms of the intentional object the thought in question is about, contend that thoughts which share a common focus do so in virtue of both thoughts simply being about the same intentional object. However, Alexander Sandgren contends that such theories face difficulties in explaining a puzzle of intentional identity put forward by Walter Edelberg, in which a pair of sentences seem to differ in truth value but are purportedly logically equivalent on the object-centric theory. If this is right, then it seems that any account which explains intentionality with reference to an intentional object is threatened by this result, whether this object be abstract, merely possible, Meinongian, or otherwise. In this paper, I argue that Edelberg’s Puzzle is analogous to Frege’s Puzzle and the same tools conventionally used to solve Frege’s Puzzle can be used to solve Edelberg’s Puzzle. I then propose a new object-centric solution to Edelberg’s Puzzle which takes into account modes of presentation and which is able to accommodate all the relevant linguistic data. (shrink)

The practice of prenatal screening for disability is sometimes objected to because of the hurt and offence such practices may cause to people currently living with disabilities. This objection is commonly termed “the expressivist objection”. In response to the objection it is standardly claimed that disabilities are analogous to illnesses. And just as it would be implausible to suppose reduction of the incidence of illnesses such as flu sends a negative message to ill people, so it is not plausible to (...) suppose prevention of disability sends a negative message to disabled people. The expressivist objection hinges, however, upon a view of the relationship between disability and self identity which sees disability as part of the identity of the disabled person, in a way in which illnesses such as flu cannot be. This possibility is generally not considered in critiques of the expressivist objection. In this paper, an “identity claim” to the effect that disabilities can be identity constituting is accepted and the force of the expressivist argument is reconsidered in the light of its acceptance. It is concluded that even when such an identity claim is accepted, the expressivist objection is still not morally compelling. (shrink)

Some critics of Don Marquis's ‘future‐like‐ours’ anti‐abortion argument launch what has been called the Identity Objection. The upshot of this objection is that under a psychological theory of personal identity, a non‐sentient fetus lacks precisely what Marquis believes gives it a right to life – a future like ours. However, Eric Vogelstein, in a recent article, has argued that under this theory of personal identity a non‐sentient fetus, in fact, has a future like ours, which he believes (...) dissolves the Identity Objection. But Vogelstein is mistaken. Even if he is correct that there is a sense in which a non‐sentient fetus has a future of value under a psychological theory of personal identity, the sense in which it has one is importantly different from the sense in which we have one, meaning that, under such a theory, a non‐sentient fetus does not have a future like ours.

The supporter of vague objects has been long challenged by the following ‘Argument from Identity’: 1) if there are vague objects, then there is ontically indeterminate identity; 2) there is no ontically indeterminate identity; therefore, 3) there are no vague objects. Some supporters of vague objects have argued that 1) is false. Noonan (Analysis 68: 174–176, 2008) grants that 1) does not hold in general, but claims that ontically indeterminate identity is indeed implied by the assumption (...) that there are vague objects of a certain special kind (i.e. vague objects*). One can therefore formulate a ‘New Argument from Identity’: 1′) if there are vague objects*, then there is ontically indeterminate identity; 2) there is no ontically indeterminate identity; therefore, 3′) there are no vague objects*. Noonan’s strategy is to argue that premiss 1′) is inescapable, and, as a consequence, that Evans’s alleged defence of 2) is a real challenge for any supporter of vague objects. I object that a supporter of vague objects who grants the validity of Evans’s argument allegedly in favour of 2) should reject premiss 1′). The threat of the New Argument from Identity is thus avoided. (shrink)

The thesis of this paper concerns the fundamental role of "ordinary objects" with respect to the structure of natural language. It ascribes their role as basic objects of reference to their being both natural and "given" individuals. Section 1 will summarize that idea. Further argument will be offered in Section 2. An objection appealing to physical theory will be answered in Section 3. Sections 4, 5, and 6 consider the implications of the thesis for current theories of the identity (...) of "ordinary objects" over time. Section 4 deals with some traditional, paradoxical, but still influen tial arguments. Section 5 focuses on four-dimensionalism and the ontology of possible worlds. Section 6 examines the theory of David Wiggins, who recognizes that biological individuals, at least, are both natural and given, but who retains a form of conceptualism. Some remarks are made through out about the wider philosophical motivations of different approaches to the topic of identity, and about the nature of philosophical "analysis.". (shrink)

In contrast to the most common view, I argue that one can consistently affirm that fundamental moral principles are objective and invariable, and yet are dependent on God. I explore and reject appealing to divine simplicity as a basis for affirming this conjunction. Rather, I develop the thesis that God is identical to the Good (the Identity View or IV) and argue that the IV does not fall to the criticisms of simplicity. I then consider a divine will theory (...) (DWT) that claims moral principles are grounded in God’s will. When the IV is conjoined with a DWT, there is reason to affirm an objective, theistically based ethics. The IV and DWT proposed here are models and while I attempt to increase their plausibility, I do not argue for their truth. The IV conjoined with a moral theory such as DWT explains the dependence of moral principles on God, while allowing for objectivity since morality is rooted in the eternal unchanging standard of the Good.

This unique anthology of new, contributed essays offers a range of perspectives on various aspects of ontic vagueness. It seeks to answer core questions pertaining to onticism, the view that vagueness exists in the world itself. The questions to be addressed include whether vague objects must have vague identity, and whether ontic vagueness has a distinctive logic, one that is not shared by semantic or epistemic vagueness. The essays in this volume explain the motivations behind onticism, such as the (...) plausibility of mereological vagueness and indeterminacy in quantum mechanics and they offer various arguments both for and against ontic vagueness; onticism is also compared with other, competing theories of vagueness such as semanticism, the view that vagueness exists only in our linguistic representation of the world. Gareth Evans’s influential paper of 1978, “Can There Be Vague Objects?” gave a simple but cogent argument against the coherence of ontic vagueness. Onticism was subsequently dismissed by many. However, in recent years, researchers have become aware of the logical gaps in Evans’s argument and this has triggered a new wave of interest in onticism. Onticism is now widely regarded as at least a coherent view. Reflecting this growing consensus, the present anthology for the first time puts together essays that are focused on onticism and its various facets and it fills in the lacuna in the literature on vagueness, a much-discussed subject in contemporary philosophy.

It is, for instance, noteworthy that he reaches the surely correct conclusion that personal identity cannot be analysed in terms of memory without so much as entertaining Bishop Butler's terse and decisive objection to any such analysis: ‘… one should really think it self-evident that consciousness of personal identity presupposes, and therefore cannot constitute, personal identity; any more than knowledge, in any other case, can constitute truth, (...) which it presupposes’.

Vague Objects and Vague Identity: New Essays on Ontic Vagueness By AkibaKen and AbasnezhadAliSpringer, 2014. x + 360 pp. £117.00.

In the philosophy of science, identity over time emerges as a central concern both as an ontological category in the interpretation of physical theories, and as an epistemological problem concerning the conditions of possibility of knowledge. In Reichenbach and subsequent writers on the problem of indistinguishable quantum particles we see the return of a contrast between Leibniz and Aquinas on the subject of individuation. The possibility of rejecting the principle of the identity of indiscernibles has certain logical difficulties, (...) leading us inexorably from ontology into epistemology. For the epistemological problem we attend to the differences that emerged between the (neo-)Kantian and logical empiricist traditions, also saliently displayed in Reichenbach's writings. After examining the contrast between Kant's and Leibniz's conceptions of empirical knowledge, specifically with respect to the irreducibility of spatiotemporal determinations, we explore an application of a neo-Kantian view to the same problem of indistinguishable quantum particles.

One of the central problems of personal identity is to determine what we are essentially . In response to this problem, Lynne Rudder Baker espouses a psychological criterion, that is, she claims that persons are essentially psychological. Baker’s theory purports to bypass the problems of other psychological theories such as Dissociative Identity Disorder and the problem of individuating persons synchronically. I argue that the theory’s treatment of Dissociative Identity Disorder leads to untenable results, is invalid, and consequently (...) fails to individuate persons. (shrink)

Crooks has rightly pointed out that perceptions are unlike the external stimuli that trigger them, and that any discussion of "objective qualia" is likely to confuse or mislead. The important issue is whether the concept of objective qualia has been just unfortunate terminology and a bad example, or whether discarding the concept seriously harms the underlying position of mind-body identity. Neuroscience research to date has been fully consistent with some version of mind-brain monism, and is beginning to establish which (...) brain areas and types of brain activity are critical for conscious awareness. Nevertheless, it is uncertain how soon, if ever, research will answer the question of why consciousness and brain activity are linked. (shrink)
