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)

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.

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.

The identity theory’s rise to prominence in analytic philosophy of mind during the late 1950s and early 1960s is widely seen as a watershed in the development of physicalism, in the sense that whereas logical behaviourism proposed analytic and a priori ascertainable identities between the meanings of mental and physical-behavioural concepts, the identity theory proposed synthetic and a posteriori knowable identities between mental and physical properties. While this watershed does exist, the standard account of it is (...) misleading, as it is founded in erroneous intensional misreadings of the logical positivists’—especially Carnap’s—extensional notions of translation and meaning, as well as misinterpretations of the positivists’ shift from the strong thesis of translation-physicalism to the weaker and more liberal notion of reduction-physicalism that occurred in the Unity of Science programme. After setting the historical record straight, the essay traces the first truly modern identity theory to Schlick’s pre-positivist views circa 1920 and goes on to explore its further development in Feigl, arguing that the fundamental difference between the Schlick-Feigl identity theory and the more familiar and influential Place-Smart-Armstrong identity theory has resurfaced in the deep and seemingly unbridgeable gulf in contemporary philosophy of consciousness between inflationary mentalism and deflationary physicalism.

Bernard Lonergan has argued for a theory of cognition that is transcendentally secure, that is, one such that any plausible attempt to refute it must presuppose its correctness, and one that also grounds a correct metaphysics and ontology. His proposal combines an identity theory of knowledge with an intentional relation between knower and known. It depends in a crucial way upon an appropriation of one’s own cognitional motives and acts, that is, upon “knowing one’s own knowing.” I (...) argue that because of conflicts between the identity and intentionality components of the theory, rational self-appropriation cannot, as Lonergan claims, be an iteration of just the same acts by which we acquire other sorts of knowledge. I propose an amended theory in which the relation between intending-subject and intended-object of first-level cognition becomes, in RSA, a numerical identity of knower and known and of the epistemic and the ontological.

The materialist version of the mind/brain identity theory has met with considerable challenges from philosophers of mind. The author first dispenses with a popular objection to the theory based on the law of indiscernibility of identicals. By means of discussing the vexatious problem of phenomenal qualities, he explores how the debate may be advanced by seeing each dualist and monist ontology through the lens of an evolutionary epistemology. The author suggests that by regarding each ontology as the (...) core of a scientific research programme, each of these logically irrefutable hypotheses can be tested rationally. (shrink)

Manzotti (2021) surveys recent variants of identity theories, defending his own preferred version, mind-object identity theory (MOI). According to this view, experiences are identical with the external objects, and the mind is thus literally “spread” in the world. Manzotti supports this view with considerations about indiscernibility of properties and other theoretical considerations. He claims that brain-mind accounts of identity commit the “fallacy of the center,” locating conscious mind inside the skull. Amongst other recent works, he comments (...) on our (Polák and Marvan, 2018) article, in which we defended a standard, neurocentrist version of type identity theory, and supplemented it with a sketch of neuro-phenomenal typing. Manzotti holds that although we appeal to neuro-phenomenal types in our account of mind-brain identity, we nevertheless “lack a convincing explanation as to why the type of neural processes should be identical to the type of one's experience.” This is a fair point. We didn't do much in our 2018 article to support our views on the principles of neuro-phenomenal typing, either by detailed theoretical considerations or by empirical evidence. In this short rejoinder, we offer the missing argument. By doing so, we also respond both to Manzotti's cited objection and to the charge of the “fallacy of the center.” -/- . (shrink)

Type identity theory was dismissed in 1967 by many philosophers due to Hilary Putnam’s multiple realisability objection seeming fatal. This paper delves into a critique of type identity theory, thereby paving the way for introducing an alternative theory of mind: emergentism. The longstanding philosophical discourse around the mind has been dominated by the binary opposition of classical physicalist and dualist theories. However, the impact of scientific discovery on contemporary thought has sparked an increasing inclination towards (...) reductive physicalist frameworks, with the aim of aligning with the scientific method. Thus, contemporary thinkers have branched out to explore new physicalistic ideas. This paper examines the inherent challenges in all reductive physicalist theories, shedding light on their limitations and proposing potential solutions to overcome the obstacles. This analysis demonstrates that type identity theory, akin to its reductive counterparts, fails to accommodate for the irreducibility of consciousness. This is consciousness as characterised by Thomas Nagel’s “what is it likeness” of experience, which is inherently subjective. Instead, this paper contends that emergentism offers a compelling alternative despite being a physicalist theory. It posits consciousness as a higher-order phenomenon, one that transcends reduction to its constituent components. I argue that this attribute of emergentism makes it a promising theory in the ongoing quest for an understanding of the mind and consciousness. (shrink)

Explanatory pluralism holds that the sorts of comprehensive theoretical and ontological economies, which microreductionists and New Wave reductionists envision and which antireductionists fear, offer misleading views of both scientific practice and scientific progress. Both advocates and foes of employing reductionist strategies at the interface of psychology and neuroscience have overplayed the alleged economies that interlevel connections (including identities) justify while overlooking their fundamental role in promoting scientific research. A brief review of research on visual processing provides support for the explanatory (...) pluralist=s general model of cross-scientific relations and discloses the valuable heuristic role hypothetical identities play in cross-scientific research. That model also supplies grounds for hesitation about the correlation objection to the psycho-physical identity theory and complaints about an explanatory gap in physicalist accounts of consciousness. These takes on psycho-neural connections miss both the sorts of considerations that motivate hypothetical identities in science and their fundamental contribution to progressive research. Thus, their focus on the contributions of research at multiple levels of analysis does not bar explanatory pluralists from considering heuristic identity theory (HIT). Arguably, it encourages it.

Jennifer Hornsby’s 1997 paper, ‘Truth: The Identity Theory’, has been highly influential in making the identity theory of truth a viable option in contemporary philosophy. In this introduction and commentary I focus on what distinguishes her theory and its methodology from the correspondence theory and the ‘substantivist’ methodology, and on other issues that have not been widely discussed in earlier commentaries yet are central to the current debate on truth.

In this paper, I address the grounding problem for contemporary Russellian panpsychism, or the question of how consciousness as an intrinsic nature is connected to dispositions or powers of objects. I claim that Russellian panpsychists cannot offer an adequate solution to the grounding problem and that they should reject the claim that consciousness, as an intrinsic nature, grounds the powers of objects. Instead, I argue that they should favour the identity theory of powers, where categorical and dispositional properties (...) are identified. I maintain that the identity theory serves as a better ontological basis for panpsychism since it avoids the grounding problem. Apart from that, I also argue that identity theory panpsychism is a position more parsimonious than Russellian panpsychism since it introduces fewer entities while successfully avoiding the grounding problem. Based on these considerations, I conclude that identity theory panpsychism is an option worth considering. (shrink)

In the 1950’s and 1960’s, Feigl, Place and Smart offered an answer to the mind‑body problem called Identity Theory. According to Identity Theory, there are physical descriptions describing the same event as first‑person descriptions of experience. In this article, we address the criticism that mind‑body identity can be refuted on logical grounds, taken in the widest sense. Kripke’s criticism to this effect, as developed in Naming and Necessity, will be our central concern. Another notorious argument (...) we will consider is Chalmers’s, as developed in The Conscious Mind. The Identity Theorists originally held that identity statements could be contingently true. Kripke argues that all true identity statements are true necessarily. If the mind‑body identity is contingent, as Kripke thinks it must be, it cannot be true. Unlike Identity Theorists, I accept that body‑mind identity must be necessary, but unlike Kripke, I argue that it can be. Central to my refutation of Kripke and Chalmers is a more elaborate approach to thinking about reference. (shrink)

This is a one page handout identifying some notable omissions from her brief history of gender identity theory.

The thesis that follows proffers a solution to the mind-matter problem, the problem as to how mind and matter relate. The proposed solution herein is a variant of panpsychism – the theory that all (pan) has minds (psyche) – that we name pansentient monism. By defining the suffix 'psyche' of panpsychism, i.e. by analysing what 'mind' is (Chapter 1), we thereby initiate the effacement of the distinction between mind and matter, and thus advance a monism. We thereafter critically examine (...) the prevalent view, antithetical to a pansentient monism, that mind is not identical to matter but emergent therefrom (Chapter 2). This anti-emergentist critique acts also as a fortification of the Genetic Argument for panpsychism: if mind is not emergent (nor distinct) from matter, mind must always have existed with matter. But what is 'matter'? Chapter 3 investigates what we understand by 'matter', or 'the physical', and exposes it as a highly deficient concept and percept that in concreto points to its identity with that denoted by 'mind'. This also acts as a fortification of the Abstraction Argument for panpsychism, employing a new taxonomy of physicalism and a new taxonomy of the varieties of abstraction. Thus do we reach a monism that is a parsimonious psycho-physical identity theory. But here we face what can be called The Identity Problem for Panpsychism: if our panpsychism is a psycho-physical identity theory, how can it respond to the powerful objections that beset the identity theory of the twentieth century? In Chapter 4 it will be argued that, like emergentism, this psycho-neural identity theory presupposed a deficient concept of 'matter', down to which mind was reduced away, let alone identified. But to identify down phenomena to what is actually an abstraction is to commit failure of explanation. When the theory is amended accordingly, we move from a psycho-neural identity theory to a genuine psycho-physical identity theory that as such can overcome the aforementioned identity problem. Furthermore, as Chapter 5 clarifies, our pansentient monism has, in addition to parsimony, the explanatory power to resolve the problem of mental causation that afflicts both the reductive physicalism of psycho-neural identity theory and the non-reductive physicalism of emergentism, by genuinely identifying physical and mental causation. Jaegwon Kim considers the place of consciousness in a physical world and the nature of mental causation to be the two key components of the mind-matter problem. Through the critical analysis of our prosaic understanding of mind and matter in this thesis, which incorporates the thought of both classical and contemporary thinkers through a novel fusion, it is hoped that both components are addressed and redressed. That is to say that I present this pansentient monism as a plausible, parsimonious, explanatory, and thus, I think, powerful position towards this ever-perplexing mind-matter mystery. -/- [This thesis was passed in January 2019 with viva examination from Galen Strawson and Joel Krueger.

Transference theorists propose to explain causation in terms of the transference of a physical element. I argue, in two steps, that this is not possible. First, I show that available accounts of ‘transference’ ultimately convey that transference -and, consequently, causation- is the (non-relational) identity over time of the transferred element (a universal, a trope, or even an absolute substance). But, second, I try to defend, it is conceptually impossible that causation is (non-relational) identity.

In this paper, I present a two-pronged argument devoted to defending the type-identity theory of mind against the argument presented by Kripke in _Naming and Necessity_. In the first part, the interpersonal case, I show that since it is not possible to establish the metaphysical conditions for phenomenal identity, it is not possible to argue that there can be physical differences between two subjects despite their phenomenal identity. In the second part, the intrapersonal case, I consider (...) the possibility of imagining one and the same individual having the same phenomenal state while counterfactually being in very different physical states. I argue that this case should respect Kripke’s implicit theory of personal identity—but this proves to be a very difficult task to accomplish, thus preventing the argument from getting off the ground. Therefore, I maintain, that the type-identity theory is still the better option to solve the mind–body problem. (shrink)

In the philosophy of mind, neuroscience, and psychology, the causal relationship between phenomenal consciousness, mentation, and brain states has always been a matter of debate. On the one hand, material monism posits consciousness and mind as pure brain epiphenomena. One of its most stringent lines of reasoning relies on a ‘loss-of-function lesion premise,’ according to which, since brain lesions and neurochemical modifications lead to cognitive impairment and/or altered states of consciousness, there is no reason to doubt the mind-brain identity. (...) On the other hand, dualism or idealism (in one form or another) regard consciousness and mind as something other than the sole product of cerebral activity pointing at the ineffable, undefinable, and seemingly unphysical nature of our subjective qualitative experiences and its related mental dimension. Here, several neuroscientific findings are reviewed that question the idea that posits phenomenal experience as an emergent property of brain activity, and argue that the premise of material monism is based on a logical correlation-causation fallacy. While these (mostly ignored) findings, if considered separately from each other, could, in principle, be recast into a physicalist paradigm, once viewed from an integral perspective, they substantiate equally well an ontology that posits mind and consciousness as a primal phenomenon.

This paper employs a case study from the history of neuroscience—brain reward function—to scrutinize the inductive argument for the so-called ‘Heuristic Identity Theory’ (HIT). The case fails to support HIT, illustrating why other case studies previously thought to provide empirical support for HIT also fold under scrutiny. After distinguishing two different ways of understanding the types of identity claims presupposed by HIT and considering other conceptual problems, we conclude that HIT is not an alternative to the traditional (...) identity theory so much as a relabeling of previously discussed strategies for mechanistic discovery.

The identity theory of mind is advocated and developed by different philosophers beginning with Place, Feigl and Smart. The main thesis of this theory is – states and processes of the mind are identical to states and processes of the brain. Although this theory is better than dualism and Behaviourism, still it has its own problems. This theory leaves many things unexplained with regard to the relation between mind and body, which have been questioned by (...) different thinkers in different periods. Hence, in this article I am going to find out only the problem of identity in the ‘Identity theory of mind’. (shrink)

This paper examines recent forms of post-identity thought within contemporary gender theory, specifically the works of Rosi Braidotti, Elizabeth Grosz and Bobby Noble. Despite the many insights that these theories offer, I argue that they suffer from what Lois McNay has labelled ‘social weightlessness’ insofar as their models of subjectivity and agency are disconnected from the everyday realities of social subjects. I identify two ways in which this social weightlessness is manifested in radical gender theories that endorse a (...) post-identity politics: (i) they overlook the social and political importance to many individuals of establishing stable, coherent identities; (ii) they are unable to offer a satisfactory account of agency. I suggest that these issues arise, at least in part, from the anti-recognition stance adopted by such radical gender theorists. I argue that by incorporating a properly nuanced model of recognition back into their theories they can imbue their accounts with a properly grounded model of the subject that is responsive to the inequalities and oppressions that infuse the particular concrete contexts in which we experience and live out our identities.

The mind-brain identity theory, the thesis that sensations are identical with properties or processes of the brain, was introduced into contemporary discussion by U.T. Place, Herbert Feigl, and J.J.C Smart in the 1950s. Despite its widespread rejection in the following decades, the identity theory has received several carefully articulated defenses in recent years. Aside from developing novel responses to well-known arguments against the identity theory, contemporary identity theorists have argued that the epistemological resources (...) available to support the adoption of identities are more plentiful than has often been supposed; further, they have argued that mind-brain identities allow for the resolution of otherwise intractable explanatory puzzles about the phenomenal properties of experience. From an epistemological perspective, identity theorists have thus argued that a central reason for believing theoretical identities—both mind-brain identities as well as more mundane identities such as water = H2O—stems from the explanatory power that they confer. Yet from an explanatory perspective, identity theorists have maintained that identities cannot themselves be explained; indeed, they have maintained that it is hardly intelligible to request an explanation for an identity. This paper considers these ideas draws out an important tension between them. The central claim is that insofar as identity theorists insist on the explanatorily efficacy of identities, they should concede that there is a good sense in which theoretical identities can be explained. However, it is moreover argued that this concession is not especially problematic and, indeed, ought to be welcomed by identity theorists. (shrink)

This paper focuses on three theories of personal identity that incorporate the idea that personal identity is the result of a person’s adopting certain attitudes towards certain mental states and actions. I call these theories subjective theories of personal identity. I argue that it is not clear what the proponents of these theories mean by “personal identity”. On standard theories, such as animalism or psychological theories, the term “personal identity” refers to the numerical identity (...) of persons and its analysis provides the persistence conditions for persons. I argue that if the subjective theories purport to provide a criterion of numerical personal identity, they fail. A different interpretation may suggest that they purport to provide a non-numerical type of identity for the purpose of providing plausible analyses of certain identity-related practical concerns. I argue that the criteria the subjective theories provide fail to capture several of the identity-related concerns. As a result, this interpretation must be rejected as well. (shrink)

Identity politics is commonly criticized as endangering democracy by undermining community, rational communication, and solidarity. Drawing on both radical democratic theory and standpoint theory, this article posits the opposite thesis: identity politics is pivotal for the democratization of democracy. Democratization through identity politics is achieved by disrupting hegemonic discourse and is, therefore, a matter of power, while such forms of power politics are reasonable when following minority standpoints generated through identity politics. The article develops (...) this approach by connecting radical democratic theories with standpoint theories and highlighting their commonalities and potential for mutual enhancement. Standpoint theory allows us to substantiate and reconcile two initially contradictory claims: particular minority standpoints are necessary to criticize the prevailing discursive and institutional orders, and these standpoints stem from intersubjective reason and embody ‘strong objectivity.’ This discussion presents a new perspective on the tension between particularity and universality, as well as the relationship between power and reason in democracy. Democratization is an oscillation between these polarities, and political theory should not aim to resolve this tension but to recognize and articulate it. Such recognition might involve elevating knowledge emerging from oppressed groups and exercising epistemic modesty when assessing specific forms of identity politics. (shrink)

This paper seeks to carve out a distinctive category of conspiracy theorist, and to explore the process of becoming a conspiracy theorist of this sort. Those on whom I focus claim their beliefs trace back to simply trusting their senses and experiences in a commonsensical way, citing what they take to be authoritative firsthand evidence or observations. Certain flat Earthers, anti-vaxxers, and UFO conspiracy theorists, for example, describe their beliefs and evidence this way. I first distinguish these conspiracy theorists by (...) contrasting them with another group that has recently received a lot of attention from the media, philosophers, and academics more broadly. I then dig more deeply into the nature of these conspiracy theorists’ epistemic self-understanding, in order to give an account of the process by which one becomes such a conspiracy theorist. I conclude with some takeaways and implications: first, I explore the implications of my account for whether these conspiracy theorists’ beliefs are rational; then, I argue that my account has practical takeaways about counteracting beliefs in misinformation, since strategies appropriate to this kind of conspiracy theorist may not be the same ones that are appropriate for other kinds.

This essay argues for a 'relationist' treatment of intentional identity sentences like (1) "Hob believes that a witch blighted Bob's mare and Nob believes that she killed Cob's sow" (Geach 1967). According to relationism, facts of the form "a believes that p and b believes that q" are not in general reducible to facts of the form "c believes that r". We first argue that extant, non-relationist treatments of intentional identity are unsatisfactory, and then go on to motivate (...) and explore a relationist alternative in some detail. We show that the general thesis of relationism can be directly motivated via cases already discussed in the literature, and then develop a particular version of relationism couched in the possible worlds framework. The resulting theory avoids the problems facing its non-relationist rivals, and yields a natural account of the truth-conditions of (1), truth-conditions which can be generated in a compositional manner by a version of dynamic semantics. The theory also helps us to cleanly separate semantic questions about intentional identity from metasemantic ones. (shrink)

In his early works, Derek Parfit famously defended revisionary reductionism about personhood. According to this view, facts about personal identity consist in the holding of more particular psychological facts, which can be described wholly impersonally. He also argued that, in some cases, the truth of this view makes questions about diachronic personal identity empty questions to which no meaningful answers can be given. Yet, in his later works, Parfit defends several ethical theories such as contractualism and rule-consequentialism, which (...) seem to rely on exactly the kind of determinate notion of personal identity to which he objected earlier. Parfit, furthermore, never explored reductionism’s consequences for such theories in his later works. In order to solve this interpretative puzzle, this chapter tries to argue that, even if they are seemingly conflicting, Parfit’s views on personal identity and rule-consequentialism, Scanlonian contractualism, and Kantian contractualism do form a coherent and unified whole.

In this article I investigate the extent to which Bhikhu Parekh believes that a person's cultural/religious background must be preserved and whether, by implication, religious schooling is justified by his theory. My discussion will explore—by inference and implication—whether Parekh's carefully crafted multiculturalism, enriched and illuminated by numerous practical insights, is socially tenable. I will also consider whether, by extension, it is justifiable, on his line of reasoning, to cultivate cultural and religious understandings among one's own children. Finally, I will (...) contend that Parekh, notwithstanding his cautious, even‐handed approach, commits several important errors, including conflating the culture of the parents with that of the children and insisting that cultural and religious persons ought to be allowed to defend their views in the public square on religious grounds.

Generally speaking, the existence of experience is accepted, but more challenging has been to say what experience is and how it occurs. Moreover, philosophers and scholars have been talking about mind and mental activity in connection with experience as opposed to physical processes. Yet, the fact is that quantum physics has replaced classical Newtonian physics in natural sciences, but the scholars in humanities and social sciences still operate under the obsolete Newtonian model. There is already a little research in which (...) mind and conscious experience are explained in terms of quantum theory. This article argues that experience is impossible to be both a physical and non-physical phenomenon. When discussing causality and identity as transcendental, quantum theory may imply the quantum physical nature of conscious experience, where a person associates causality to conscious experience, and, thus, the result is that the double-aspect theory and the mind/brain identity theory would be refuted.

Body Integrity Identity Disorder (BIID) is a very rare condition describing those with an intense desire or need to move from a state of ability to relative impairment, typically through the amputation of one or more limbs. In this paper, I draw upon research in critical disability studies and philosophy of disability to critique arguments based upon the principle of nonmaleficence against such surgery. I demonstrate how the action-relative concept of harm in such arguments relies upon suspect notions of (...) biological and statistical normality, and I contend that each fail to provide normative guidance. I then propose a critical theory of harm, one marked by substantive engagement with both empirical and reflective inquiry across the sciences, social sciences, and humanities. I conclude by discussing the implications of this theory and how it might enrich ongoing debates in bioethics, philosophy of disability, and the health humanities. (shrink)

This paper disputes a common definition of token identity theory. It also observes that within the philosophical literature there are two significantly different definitions of token identity theory that are commonly used.

The identity theory, advocated as a solution to the mind-body problem by materialists such as Feigl and Smart, has been criticized for implying the existence of irreducible properties. After summarizing the relevant theses of materialism, I consider several versions of the irreducible properties objection, and argue that they are all unsuccessful.

Goffman’s (1959) dramaturgical identity theory requires modification when theorising about presentations of self on social media. This chapter contributes to these efforts, refining a conception of digital identities by differentiating them from ‘corporatised identities’. Armed with this new distinction, I ultimately argue that social media platforms’ production of corporatised identities undermines their users’ autonomy and digital well-being. This follows from the disentanglement of several commonly conflated concepts. Firstly, I distinguish two kinds of presentation of self that I collectively (...) refer to as ‘expressions of digital identity’. These digital performances (boyd 2007) and digital artefacts (Hogan 2010) are distinct, but often confused. Secondly, I contend this confusion results in the subsequent conflation of corporatised identities – poor approximations of actual digital identities, inferred and extrapolated by algorithms from individuals’ expressions of digital identity – with digital identities proper. Finally, and to demonstrate the normative implications of these clarifications, I utilise MacKenzie’s (2014, 2019) interpretation of relational autonomy to propose that designing social media sites around the production of corporatised identities, at the expense of encouraging genuine performances of digital identities, has undermined multiple dimensions of this vital liberal value. In particular, the pluralistic range of authentic preferences that should structure flourishing human lives are being flattened and replaced by commercial, consumerist preferences. For these reasons, amongst others, I contend that digital identities should once again come to drive individuals’ actions on social media sites. Only upon doing so can individuals’ autonomy, and control over their digital identities, be rendered compatible with social media. (shrink)

Property-identical divine-command theory (PDCT) is the view that being obligatory is identical to being commanded by God in just the way that being water is identical to being H2O. If these identity statements are true, then they express necessary a posteriori truths. PDCT has been defended in Robert M. Adams (1987) and William Alston (1990). More recently Mark C. Murphy (2002) has argued that property-identical divine-command theory is inconsistent with two well-known and well-received theses: the free-command thesis (...) and the supervenience thesis. I show that Murphy's argument is vitiated by mistaken assumptions about the substitutivity of metaphysical identicals in contexts of supervenience. The free-command thesis and the supervenience thesis therefore pose no serious threat to PDCT. (Published Online August 11 2004). (shrink)

Background. Drawing on social identity theory and positive psychology, this study investigated women’s responses to the social environment of physics classrooms. It also investigated STEM identity and gender disparities on academic achievement and flourishing in an undergraduate introductory physics course for STEM majors. 160 undergraduate students enrolled in an introductory physics course were administered a baseline survey with self-report measures on course belonging, physics identification, flourishing, and demographics at the beginning of the course and a post-survey at (...) the end of the academic term. Students also completed force concept inventories and physics course grades were obtained from the registrar. Results. Women reported less course belonging and less physics identification than men. Physics identification and grades evidenced a longitudinal bidirectional relationship for all students (regardless of gender) such that when controlling for baseline physics knowledge: (a) students with higher physics identification were more likely to earn higher grades; and (b) students with higher grades evidenced more physics identification at the end of the term. Men scored higher on the force concept inventory than women, although no gender disparities emerged for course grades. For women, higher physics (versus lower) identification was associated with more positive changes in flourishing over the course of the term. High-identifying men showed the opposite pattern: negative change in flourishing was more strongly associated with high identifiers than low identifiers. Conclusions. Overall, this study underlines gender disparities in physics both in terms of belonging and physics knowledge. It suggests that strong STEM identity may be associated with academic performance and flourishing in undergraduate physics courses at the end of the term, particularly for women. A number of avenues for future research are discussed. (shrink)

A theory of gender ought to be compatible with trans-inclusive definitions of gender identity terms, such as ‘woman’ and ‘man’. Appealing to this principle of trans-inclusion, Katharine Jenkins argues that we ought to endorse a dual social position and identity theory of gender.

A main element in Richard Swinburne’s (2019) argument for substance dualism concerns the conditions of a person’s continued existence over time. In this commentary I aim to question two things: first, whether the kind of imaginary cases that Swinburne relies on to make his case should be accorded the kind of weight he supposes; and second, whether philosophers should be concerned to give any substantial theory, of the sort that dualism and its competitors are apparently meant to provide, to (...) explain the conditions of personal identity after all. My suggestion, instead, will be that the concept of a person’s continued existence is better taken as philosophically unanalyzable. (shrink)

There are well-known quasi-formal arguments that identity is a "strict" relation in at least the following three senses: (1) There is a single identity relation and a single distinctness relation; (2) There are no contingent cases of identity or distinctness; and (3) There are no vague or indeterminate cases of identity or distinctness. However, the situation is less clear cut than it at first may appear. There is a natural formal theory of identity that (...) is very close to the standard classical theory but which does not validate the formal analogues of (1)-(3). The core idea is simple: We weaken the Principle of the Indiscernibility of Identicals from a conditional to an entailment and we adopt a weakly classical logic. This paper investigates this weakly classical theory of identity (and related theories) and discusses its philosophical ramifications. It argues that we can accept a reasonable theory of identity without committing ourselves to the uniqueness, necessity, or determinacy of identity. (shrink)

In this essay I shall argue that the crucial assumptions of Kripke's argument, i.e. the collapse of the appearance/reality distinction in the case of phenomenal states and the idea of a qualitatively identical epistemic situation, imply an objective principle of identity for mental-state types. This principle, I shall argue, rather than being at odds with physicalism, is actually compatible with both the type-identity theory of the mind and Kripke's semantics and metaphysics. Finally, I shall sketch a version (...) of the type-identity theory. (shrink)

In this paper, I defend the idea that we need a metaphysical theory to justify identity-related practical concerns, such as self-concern. I outline D. Parfit’s theory, in which the concerns receive a metaphysical justification. Then, I focus on two objections: C. Korsgaard’s claim that the concerns are justified by the unity of agency, and M. Johnston’s contention that the concerns are prima facie justified independently of a metaphysical theory. I argue that even if these theories have (...) a point, they do not cover a range of situations in which justification may be sought. It is in these situations that a metaphysical theory may find its place. (shrink)

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory (...) of personal identity. But the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

Derek Parfit famously argued that personal identity is not what matters for prudential concern about the future. Instead, he argues what matters is Relation R, a combination of psychological connectedness and continuity with any cause. This revisionary conclusion, Parfit argued, has profound implications for moral theory. It should lead us, among other things, to deny the importance of the separateness of persons as an important fact of morality. Instead, we should adopt impersonal consequentialism. In this paper, I argue (...) that Parfit is mistaken about this last step. His revisionary arguments about personal identity and rationality have no implications for moral theory. We need not decide whether Relation R or personal identity contain what matters if we want to retain the importance of the separateness of persons. (shrink)

Identity in the philosophical literature has until recently be confined mostly to ruminations on the self: as soul in Plato; rationality connected to, but not coterminous with, the body in Descartes; uninterrupted consciousness in Locke; a stream of experiences which a thing has in relation to itself in Hume; an emotive life in Rousseau; as noumenal self about which we can know little in Kant; as will in Schopenhauer; as an elusive but nonspecific something in Wittgenstein; and as the (...) continuous, purposive struggle of creative power against an historically contingent concatenation of social, political, and cultural forces in Nietzsche and Foucault. Yet what follows is not a summary of metaphysics or philosophy of mind. There also is not sufficient space here to examine identity in each of the separate disciplines. Instead, what follows are some prefatory discursive remarks about identity; then, owing to the dominance of psychological theories on identity, a brief overview of some of its salient themes will be adumbrated; this will be followed by a discussion on identity formation and maintenance both in political philosophy and philosophy of education.

This paper develops a theory of propositional identity which distinguishes necessarily equivalent propositions that differ in subject-matter. Rather than forming a Boolean lattice as in extensional and intensional semantic theories, the space of propositions forms a non-interlaced bilattice. After motivating a departure from tradition by way of a number of plausible principles for subject-matter, I will provide a Finean state semantics for a novel theory of propositions, presenting arguments against the convexity and nonvacuity constraints which Fine (2016, (...) 2017a,b) introduces. I will then move to compare the resulting logic of propositional identity (PI) with Correia’s (2016) logic of generalised identity (GI), as well as the first degree fragment of Angell’s (1989) logic of analytic containment (AC). The paper concludes by extending PI to include axioms and rules for a subject-matter operator, providing a much broader theory of subject-matter than the principles with which I will begin. (shrink)

The purpose of this article is to introduce, interpret, and develop two incompatible process -ontological theories of personal identity that have received little attention in analytic metaphysics. The first theory derives from the notion of personal identity proposed in Alfred North Whitehead’s philosophy, but I interpret this notion differently from previous commentators. The Whiteheadian theory may appeal to those who believe that personal identity involves an entity or entities that are essentially dynamic, but has nothing (...) to do with diachronic objectual identity : the binary equivalence relation that every entity bears to itself, and only to itself, even after undergoing intrinsic change. The Whiteheadian theory may also find favor with those who, like Whitehead, reject the possibility of pure processes and hold that in every becoming, something—which need not be an object, thing, or individual substance—becomes. The second theory derives from the notion of recurrent dynamics presented in Johanna Seibt’s General Process Theory. The Seibtian theory may appeal to those who believe that personal identity involves not only an entity or entities that are essentially dynamic, but also the relation of diachronic objectual identity. The Seibtian theory may also find favor with those who, like Broad and Sellars, find reason to postulate pure processes. (shrink)

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for future work on (...) personal identity. (shrink)

Recently, several philosophers have defended an explanatory argument that supposedly provides novel empirical grounds for accepting the type identity theory of phenomenal consciousness. They claim that we are justified in believing that the type identity thesis is true because it provides the best explanation for the correlations between physical properties and phenomenal properties. In this paper, I examine the actual role identities play in science and point out crucial shortcomings in the explanatory argument. I show that the (...) supporters of the argument have failed to show that the identity thesis provides a satisfactory explanation for the correlations between physical and phenomenal properties. Hence, the explanatory argument, as it stands, does not provide new grounds for accepting the type identity theory. (shrink)

Relative to any reasonable frame, satisfiability of modal quantificational formulae in which “= ” is the sole predicate is undecidable; but if we restrict attention to satisfiability in structures with the expanding domain property, satisfiability relative to the familiar frames (K, K4, T, S4, B, S5) is decidable. Furthermore, relative to any reasonable frame, satisfiability for modal quantificational formulae with a single monadic predicate is undecidable ; this improves the result of Kripke concerning formulae with two monadic predicates.

The problem of diachronic personal identity is this: what explains why a person P1 at time T1 is numerically identical with a person P2 at a later time T2, even if they are not at those times qualitatively identical? One traditional explanation is the soul theory, according to which persons persist in virtue of their nonphysical souls. I argue here that this view faces a new and arguably insuperable dilemma: either souls, like physical bodies, change over time, in (...) which case the soul theory faces an analogue problem of diachronic soul identity, or souls, unlike physical bodies, do not change over time, in which case the soul theory cannot explain why souls relate to particular bodies over time and so at best only partially explains personal identity. I conclude that the soul theory fares no better than physicalist-friendly accounts of personal identity such as bodily- or psychological-continuity-based views. (shrink)
