Identity theories are those that hold that 'sensations are brain processes'. In particular, they hold that mental/psychological state kinds are identical to brain/neuroscientific state kinds. In this paper, I isolate and explain some of the key features of contemporary identity theories. They are then contrasted with the main live alternatives by means of considering the two most important lines of objection to identity theories.

Dispositionality and qualitativity are key notions to describe the world that we inhabit. Dispositionality is a matter of what a thing is disposed to do in certain circumstances. Qualitativity is a matter of how a thing is like. According to the Identity Theory of powers, every fundamental property is at once dispositional and qualitative, or a powerful quality. Canonically, the Identity Theory holds a contentious identity claim between a property’s dispositionality and its qualitativity. In the (...) literature, this view faces a contradiction objection that undermines its merits. We should therefore consider an alternative version that does not embrace the identity claim. My aim is to show that we can enjoy the benefits of the Identity Theory without embracing the identity between the dispositional and the qualitative. I shall argue that a distinction between two senses of dispositionality and qualitativity serves the purpose. I will then discuss three readings of the identity claim that can be formulated in light of such a distinction. I will conclude that even if the identity were to fail in any of the suggested readings, it would be possible to hold an account of fundamental powerful qualities. (shrink)

This book argues that correspondence theories of truth fail because the relation that holds between a true thought and a fact is that of identity, not correspondence. Facts are not complexes of worldly entities which make thoughts true they are merely true thoughts. According to Julian Dodd, the resulting modest identity theory, while not defining truth, correctly diagnoses the failure of correspondence theories, and thereby prepares the ground for a defensible deflation of the concept of truth.

This is about a proposed solution to the exclusion problem, one I've defended elsewhere. Details aside, it's just the identity theory : mental properties face no threat of exclusion from, or preemption by, physical properties, because every mental property is a physical property. Here I elaborate on this solution and defend it from some objections. One of my goals is to place it in the context of a more general ontology of properties, in particular, a trope ontology.

Functionalists in philosophy of mind traditionally raise two major arguments against the type identity theory: (1) psychological states are _multiply realizable_ so that there are no one-to-one mappings of psychological states onto neural states and (2) the most that evidence could ever establish is the _correlation_ of psychological and neural states, not their identity. We defend a variant on the traditional type identity theory which we call _heuristic identity theory_ (HIT) against both of these (...) objections. Drawing its inspiration from scientific practice, heuristic identity theory construes identity claims as hypotheses that guide subsequent inquiry, not as conclusions of the research. (shrink)

is true, there is a truth-maker (e.g., a fact) with which it is identical and the truth of the former consists in its identity with the latter. The theory is best understood as a reaction to the correspondence theory, according to which the relation of truth-bearer to truth-maker is correspondence. A correspondence theory is vulnerable to the nagging suspicion that if the best we can do is make statements that merely correspond to the truth, then we (...) inevitably fail to capture the reality they are about and thus fall short of the truth we aim at. An identity theory is designed to overcome this suspicion. (shrink)

The paper is concerned with the idea that the world is the totality of facts, not of things – with what is involved in thinking of the world in that way, and why one might do so. It approaches this issue through a comparison between Wittgenstein’s Tractatus and the identity theory of truth proposed by Hornsby and McDowell.The paper’s positive conclusion is that there is a genuine affinity between these two. A negative contention is that the modern (...) class='Hi'>identity theory is vulnerable to a complaint of idealism that the Tractatus can deflect. (shrink)

The concept of identity has become widespread within the social and behavioral sciences in recent years, cutting across disciplines from psychiatry and psychology to political science and sociology. All individuals claim particular identities given their roles in society, groups they belong to, and characteristics that describe themselves. Introduced almost 30 years ago, identity theory is a social psychological theory that attempts to understand identities, their sources in interaction and society, their processes of operation, and their consequences (...) for interaction and society from a sociological perspective. This book describes identity theory, its origins, the research that supports it, and its future direction. It covers the relation between identity theory and other related theories, as well as the nature and operation of identities. In addition, the book discusses the multiple identities individuals hold from their multiple positions in society and organizations as well as the multiple identities activated by many people interacting in groups and organizations. And, it covers the manner in which identities offer both stability and change to individuals. Written in an accessible style, Identity Theory makes, step by step, the full range of this powerful new theory understandable to readers at all levels. (shrink)

In social psychology, we need to establish a general theory of the self, which can attend to both macro and micro processes, and which avoids the redundancies of separate theories on different aspects of the self. For this purpose, we present core components of identity theory and social identity theory and argue that although differences exist between the two theories, they are more differences in emphasis than in kind, and that linking the two theories can (...) establish a more fully integrated view of the self. The core components we examine include the different bases of identity (category/group or role) in each of the theories, identity salience and the activation of identities as discussed in the theories, and the cognitive and motivational processes that emerge from identities based on category/group and on role. By examining the self through the lens of both identity theory and social identity theory, we see how, in combination, they can move us toward a general theory of the self. (shrink)

In social identity theory, the in-Christ identity is understood as primarily a socially directed process in which people categorise themselves relative to other groups. Intergroup behaviour would cause them to discriminate against the so-called ‘outgroup’, favouring the so-called ‘ingroup’. Although social identity complexity theory has moved beyond single ingroup-outgroup categorisation, it is a question if social identity theories can fully account for the in-Christ identity, especially within an African context. In African religious (...) class='Hi'>identity, identity is linked to both the community and the ruling deities, which are perceived to be real entities that intervene in human affairs and identity, presupposing a supernaturalistic epistemology. Contribution: In this contribution, the naturalistic epistemological underpinnings of social identity theories are reconsidered in light of a supernatural aspect that is argued to be constitutive of the 1st century in-Christ identity as well as the African Christian identity. Amid current approaches to the in-Christ identity, which is mainly a Pauline concept, some of the main Pauline texts that have bearing on the in-Christ identity are revisited in light of current theories and epistemologies on identity.

THE Identity Theory of Herbert Feigl is an elaborate and painstaking attempt to overcome the perplexities of the mind-body problem which Anglo-Saxon philosophers have inherited from Descartes and which has been compounded by the empiricist heritage of Hume. In common with influential contemporaries such as Russell, Ryle, Strawson and Hampshire, Feigl believes that the substance dualism of Descartes is an incoherent doctrine. There can be no adequate account of the nature and status of the person if mind and (...) body, conscious immaterial self and extended corporeal substance are regarded as distinct and disparate entities. It is paradoxical however and indicative of the pervasive influence of the Cartesian framework, that the Identity Theory combines an explicit rejection of dualism with an uncompromising acceptance and even extension of another feature of that framework, in that it hinges on a more comprehensive reliance on the knowledge claims of science than even Descartes was prepared to sanction.

Identity theory The doctrine that mental states are identical with physical states was defended in antiquity by Lucretius and in the early modern era by Hobbes. It achieved considerable prominence in the 1950s as a result of the writings of Herbert Feigl, U. T. Place, and J. J. C. Smart. (See, e.g., Smart (1959). These authors developed reasonably precise formulations of the doctrine, clarified the grounds for embracing it, and responded persuasively to a range of objections. More recently (...) it has been defended systematically by Hill (1991) and Papineau (2002). Other contemporary advocates include Loar (1990), McLaughlin (2004), and Polger (2005). The doctrine also figures explicitly or implicitly in the writings of dualists, who are of course concerned to oppose it. Thus, for example, it plays an important role in Kripke’s influential defense of dualism (Kripke 1980). (shrink)

The identity theory of truth takes on different forms depending on whether it is combined with a dual relation or a multiple relation theory of judgment. This paper argues that there are two significant problems for the dual relation identity theorist regarding thought’s answerability to reality, neither of which takes a grip on the multiple relation identity theory.

In ‘On McDowell's identity conception of truth’ , we suggested that McDowell's Identity Theory, according to which a proposition is true if and only if it is identical with a fact, is only fully understood when we realize that there are two identity claims involved. The first is that, when one thinks truly, the content of a whole thought is identical with a Tractarian Tatsachen – a complex fact constituted by simple Sachverhalte – and the second (...) is that these simple Sachverhalte are in turn identical with simple Fregean senses. 1As an example, we suggested that the complex content/proposition/Fregean sense is identical with the Tractarian Tatsachen constituted by the two Sachverhalte: the object's being a tiger and the object's being undernourished, both of which can be seen, as the second identity with simple Fregean senses requires, to present an object in a certain way – as being, in turn, a tiger and undernourished.In his response to our article, Julian Dodd raises three internal criticisms concerning the coherence of the view as a whole, as well as the interpretative criticism that, regardless of the internal coherence of the view, it is not McDowell's. We think that Dodd fails to appreciate the view we have developed in our article, so much so that he believes that his own proffered view of McDowell, articulated in the final section of his response, is an alternative to our own position when in fact it is simply a restatement of that position. Because this point is so fundamental, we begin below by spelling out exactly where Dodd's understanding of our view goes wrong and so why his interpretative criticism misses its target before addressing the internal criticisms concerning the coherence of the view as a ….

I identify a class of arguments against multiple realization (MR): BookofSand arguments. The arguments are in their general form successful under reasonably uncontroversial assumptions, but this, on the other hand, turns the table on identity theory: If arguments from MR can always be refuted by BookofSand arguments, is identity theory falsifiable? In the absence of operational demarcation criteria, it is not. I suggest a parameterized formal demarcation principle for brain state/process types and show how it can (...) be used to identify previously unconsidered contenders for evidence for MR, e.g., binary classification, division, and sorting. For these to be actual instances of MR, the corresponding psychological kinds must be verifiably, relevantly similar. I also briefly discuss possible linguistic, behavioral, and experimental demarcation criteria for psychological kinds. (shrink)

The identity theory of mind holds that states and processes of the mind are identical to states and processes of the brain. Strictly speaking, it need not hold that the mind is identical to the brain. Idiomatically we do use ‘She has a good mind’ and ‘She has a good brain’ interchangeably but we would hardly say ‘Her mind weighs fifty ounces’. Here I take identifying mind and brain as being a matter of identifying processes and perhaps states (...) of the mind and brain. Consider an experience of pain, or of seeing something, or of having a mental image. The identity theory of mind is to the effect that these experiences just are brain processes, not merely correlated with brain processes. (shrink)

Until recently, the powerful qualities view about properties has been effectively identified with the so-called identity theory. Yet, the difficulties that the latter faces (especially concerning the interpretation of its core claim that dispositionality and qualitativity are identical) have led some metaphysicians to propose (at least provisionally) new versions of the powerful qualities view. This paper discusses the prospects of three such versions: the compound view, the higher-order properties theory and the dual aspect account. It is argued (...) that the compound view is in fact property dualism in disguise, while the higher-order properties theory does not by itself provide a metaphysically convincing solution to Armstrong’s dilemma concerning the modal status of the relation between dispositionality and categoricality. Finally, it is argued that it is not clear whether the dual aspect account is distinct from identity theory and pure powerism. (shrink)

Identity disturbances are common in clinical conditions and personality measures need to extend to assessment of coherence in underlying levels of self-coherence. The problem has been difficult to solve because self-organization is a complex unconscious set of mind/brain processes embedded in social roles and values. Theory helps us address this problem and suggests methods and limitations of interpretation that involve self-reports of subjects, observers who rate subjects, and narrative analyses of verbal communications from subjects.

Previously unpublished passages from the Cairns Nachlass are assembled and commented on to present the identity theory in contrast with the traditional coherence and correspondence theories, and then seven more detailed analyses of related aspects are also edited.To say that a syntactical object is true or is a fact, is to say that the act of intending it as having a perhaps indistinct structure and a perhaps obscure material content may unite in a positive synthesis of identification with (...) an act wherein “the same” syntactical object is distinctly and clearly evident as having “the same” structure and content. The fulfilling act is eo ipso a grasping of the still grasped syntactical object as having been produced by a syntactical activity founded in original explication of the subject-matter. The realization of such a synthesis is a verification of the truth of the syntactical object, a verification of the “existence” of the fact.Se reúnen y comentan pasajes inéditos del Nachlass de Cairns para presentar la teoría de la identidad en contraste con las tradicionales de la coherencia y la correspondencia, también se editan luego siete análisis más detallados de aspectos relacionados.Decir que un objeto sintáctico es cierto o es un hecho, es decir que el acto de mentarlo como teniendo una estructura tal vez confusa y un contenido material tal vez os-curo, puede unir en una síntesis positiva de identificación con un acto en el que "el mismo" objeto sintáctico es clara y evidentemente teniendo "la misma" estructura y contenido. El acto de cumplimiento es eo ipso un captación del objeto sintáctico todavía captado como habiendo sido producido por una actividad sintáctica fundada en explicación original de la materia. La realización de tal síntesis es una verificación de la verdad del objeto sintáctico, una verificación de la "existencia" del hecho. (shrink)

The need to fill three gaps in ethics research in a business context sparked the current study. First, the distinction between the concepts of “ethical” and “legal” needs to be incorporated into theory building and empiricism. Second, a unifying theory is needed that can explain the variables that influence managers to emphasize ethics and legality in their judgments. Third, empirical evidence is needed to confirm the predictive power of the unifying theory, the discernable influence of personal and (...) organizational variables, and the importance of the issue to the managers in determining their emphasis on the ethical and legal values of their judgments. Focused on these needs, the current research combines social identity theory with empirical findings from business ethics research. This theory building initiative framed hypothesis-driven research to investigate the influences on managers’ emphasis on ethical and legal values in making business judgments. An empirical research study was conducted involving 252 practicing managers who judged 12 newsworthy business events. Data was collected on the managers’ individual factors, on the groups that influence their judgments, and on the importance that the managers place on ethics and legality in judging the 12 scenarios. The research findings contribute to theory development (1) By successfully utilizing a blended extension of social identity and issue-contingent theories to understand managers’ judgments, and (2) By providing evidence on the relationships between the perceived importance of an issue and the emphases managers place on ethical and legal values in their judgments. The analysis of the data was extended to provide insights on the needs of employers to tailor management training on legal and ethical decision-making. The participating managers were clustered according to their emphases on Ethical Importance and Legal Importance in judging business situations. Analysis of Variance was then combined with Scheffé Multiple Comparison Tests to assess whether the factors derived from a blended extension of social identity and issue-contingent theories were significantly different across the clusters. The product of this analysis is unique sets of attributes that describe each cluster of managers, and provide an empirical basis for determining training priorities. Finally, the carefully constructed and thoroughly tested 12 research scenarios that form the core of the survey instrument enable their redeployment in subsequent research and their use by practicing executives who wish to compare data provided by their managers to results from the study participants.

In Descartes's time the issue between materialists and their opponents was framed in terms of substances. Materialists such as Thomas Hobbes and Pierre Gassendi maintained that people are physical systems with abilities that no other physical systems have; people, therefore, are special kinds of physical substance. Descartes's DUALISM, by contrast, claimed that people consist of two distinct substances that interact causally: a physical body and a nonphysical, unextended substance. The traditional.

The main thesis of this paper is that John McDowell (in his Mind and World) tries to occupy a position that is not coherently statable; namely, that facts have objects and properties as constituents and are yet identical with true (Fregean) Thoughts. This position is contrasted with two other identity theories of truth: the robust theory, in which true propositions are identified with facts (which are understood to have objects and properties as constituents); and the modest theory, (...) in which facts are identified with true Fregean Thoughts. I argue that the modest theory is to be preferred. (shrink)

This collection of essays aims to investigate the complex issues surrounding contemporary cultural discourses on land and identity – their production, construction, and reconstruction across a range of different texts and materials. The chapters offer disciplinary and trans-disciplinary approaches opening up discussion and new routes for research in a number of interrelated areas such as Countryside vs. City, Diaspora, Landscapes of Memory and Trauma, Migrational Spaces, and Ecology. They represent a number of innovative contemporary responses to how concepts of (...) land intersect and dialogue with notions of identity across and between regions, nations, races, and cultures. Through employing interdisciplinary methods and theories drawn from diverse sources, such as cultural studies, spatial theory, philosophy and literary theory, the chapters chart varied and complex themes of identity formation in relation to spatiality.

This paper defends a version of Davidson’s demonstrative theory of quotation and against against the Fregean identity theory (IT henceforth) as articulated and defended by Corey Washington (1992). On the Fregean view, when an expression is referred to by means of quotation the quoted material itself is a linguistic referring expression. Quotation-marks are not needed; when they are used, they serve to make clearer the shift in syntactic and semantic properties effected on the quoted material by its (...) occupying that linguistic context: whatever its usual syntactic function, the quoted material functions as a singular term; whatever its usual semantic function, in that linguistic environment the quoted material refers to itself. On DT, in contrast, quotation-marks themselves are the linguistic bearers of reference, functioning like a demonstrative; the quoted material merely plays the role of a demonstratum. In the version I argue for the referent is obtained through some contextually suggested relation; in the default case the relation will be: … instantiates the linguistic type __, but there are other possibilities. In this way, the view can deal with the fact that we do not merely refer with quotations to expression-types, but also to other entities related in some way to the relevant token we use: features exhibited by the token distinct from those constituting its linguistic type, features exhibited by other tokens of the same type but not by the one actually used (as when, by using a graphic token, we refer to its phonetic type), or even other related tokens.

In the literature on multiple realizability and the identity theory, cases of neural plasticity have enjoyed a very limited role. The present article attempts to remedy this small influence by arguing that clinical and experimental evidence of quite extensive neural reorganization offers compelling support for the claim that psychological kinds are multiply realized in neurological kinds, thus undermining the identity theory. In particular, cases are presented where subjects with no measurable psychological deficits also have vast, though (...) gradually received, neurological damage. Common objections and concerns are also discussed and rejected. 1 Introduction2 The GRP, Serial Lesion Effect, and Multiple Realizability2.1 A case study of the serial lesion effect2.2 Evaluating the case study’s evidence for multiple realizability3 The GRP More Generally4 Objections to the GRP as Evidence for Multiple Realizability4.1 Small plastic effects and neurological taxonomies4.2 But do neural regions and locations even matter at all?4.3 But are there not other options besides location?5 Conclusion.
