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.

Searle's (1990) argument for the seems to rest on a confusion between ontological and epistemological claims. The potential consciousness of a mental state does not yield the same effect as does its actual consciousness, namely, the preservation of aspectual shape. Searle's distinction between the consciousness of an intentional object and that of a mental state, which is meant to counter the objection that deep unconscious rules cease to be deep once they become conscious, fails to do its appointed task.

Putnam raises two objections against the token-identity theory in his _Dewey Lectures. (1) Token-physicalism invokes a mysterious or _sui generis concept of identity between mental and physical event tokens; (2) The theory suffers from explanatory failure because it cannot individuate mental events using physical criteria. I argue that the first claim is false, since Davidson adopts the same criterion of identity Quine employs for ordinary objects which invokes a concept of identity we understand clearly (...) enough. I then show that Putnam's second complaint is an extravagant demand that needs not be answered and is at odds with his own direct realism. (shrink)

The thesis of "token identity" or "token physicalism" advanced by fodor and others attempts to reconcile materialism with a non-Reductionist view of the special sciences. However, I argue that since the individual events or "tokens" of any science are only designated according to its general types, The former cannot be specified physicalistically while the latter are not. Though attempting to combat a positivistic view of the sciences, Fodor's thesis rests on a positivistic opposition of token and (...) type. (shrink)

Donald Davidson espouses two fundamental theses about the individuation of mental events. The thesis of causal individuation asserts that sameness of cause and effect is sufficient and necessary for event identity. The thesis of content individuation gives only a sufficient condition for difference of mental events: if e and f have different contents then they are different mental events. I argue that given these theses, psychological externalism--the view that mental content is determined by factors external to the subject of (...) the relevant mental events--entails that the token identity theory is false.

This study has two goals. The first is to identify three desiderata required for a successful defense of a version of nonreductive physicalism: semantic externalism, token‐identity between mental and physical events, and nonrelational type‐individuation of physical states. In this context, the paper also presents a refutation of recent challenges to content‐externalism by those who attempt to resuscitate internalism by focusing on narrow content associated with the fundamental phenomenology, rather than the intentionality, of mental states. The second goal is (...) to defend the token‐identity thesis from Tyler Burge's argument to the effect that token‐identity is incompatible with semantic externalism. An account is also offered as to why Burge's argument, albeit fallacious, might seem persuasive under a certain interpretation of possible worlds. (shrink)

We make how a person acts intelligible by revealing it as rational in the light of what she perceives, thinks, wants and so on. For example, we might explain that she reached out and picked up a glass because she was thirsty and saw that it contained water. In doing this, we are giving a causal explanation of her behaviour in terms of her antecedent beliefs, desires and other attitudes. Her wanting a drink and realizing that the glass contained one (...) caused her reaching out and grasping for it. This tells us how the action came about and makes sense of why it happened. At least, something broadly along these lines strikes me as a fairly crude and partial regimentation of our pretheoretic understanding of everyday action explanation. (shrink)

E. J. Lowe argues that the mental event token cannot be identical to the complex neural event token for they have different counterfactual properties. If the mental event had not occurred, the behavior would not have ensued, while if the neural event had not occurred, the behavior would have ensued albeit slightly differently. Lowe's argument for the neural counterfactual relies on standard possible world semantics, whose evaluation of such counterfactuals is problematic. His argument for the mental counterfactual relies (...) on a premise that is plausibly false. My arguments support other counterfactuals, which are consistent with identity theories. (shrink)

This paper addresses ethical challenges posed by a robot acting as both a general type of system and a discrete, particular machine. Using the philosophical distinction between “type” and “token,” we locate type-token ambiguity within a larger field of indefinite robotic identity, which can include networked systems or multiple bodies under a single control system. The paper explores three specific areas where the type-token tension might affect human–robot interaction, including how a robot demonstrates the highly personalized (...) recounting of information, how a robot makes moral appeals and justifies its decisions, and how the possible need for replacement of a particular robot shapes its ongoing role. We also consider how a robot might regard itself as a replaceable token of a general robotic type and take extraordinary actions on that basis. For human–robot interaction robotic type-token identity is not an ontological problem that has a single solution, but a range of possible interactions that responsible design must take into account, given how people stand to gain and lose from the shifting identities social robots will present.

Miranda Fricker maintains that testimonial injustice is a matter of credibility deficit, not excess. In this article, I argue that this restricted characterization of testimonial injustice is too narrow. I introduce a type of identity-prejudicial credibility excess that harms its targets qua knowers and transmitters of knowledge. I show how positive stereotyping and prejudicially inflated credibility assessments contribute to the continued epistemic oppression of marginalized knowers. In particular, I examine harms such as typecasting, compulsory representation, and epistemic exploitation and (...) consider what hearers are obligated to do in response to these injustices. I argue that because epistemic harms to marginalized knowers also arise from prejudicially inflated assessments of their credibility, the virtue of testimonial justice must be revised to remedy them.

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

Charles S. Peirce introduces the distinction between a token and a type into semiotics and philosophy by using as an example two ways of individuating words:(P1) A common mode of estimating the amount of matter in a MS. or printed book is to count the number of words. There will ordinarily be about twenty the's on a page, and of course they count as twenty words. In another sense of the word "word," however, there is but one word "the" (...) in the English language; and it is impossible that this word should lie visibly on a page or be heard in any voice, for the reason that it is not a Single thing or Single event. It does not exist; it only determines things that do exist. Such a definitely significant Form, I propose.. (shrink)

The argument from causal overdetermination is considered to be the shortest route to token monism. It only assumes that:1.Efficacy: Mental events are causes of physical events.2.Closure: Every physical event has a sufficient physical cause.3.Exclusion: Systematic Causal Overdetermination is impossible: if an event x is a sufficient cause of an event y then no event x* distinct from x is a cause of y.4.Identity: Therefore, mental events are physical events.Exclusion does not deny the possibility of two gunmen that fi (...) re at a victim at the same time.

In his (1977) "Anomalous Monism and Kripke's Cartesian Intuitions," Colin McGinn argues that Donald Davidson's anomalous monism is untouched by Kripke's (1980) argument against the identity theory. The type-identity of the physical with the mental may very well fall at the feet of Kripke's powerful arguments, but a token identification, argues McGinn, is left standing due to the simple fact that token physicalism countenances a kind of imagined separation of token mental states with their corresponding (...) token physical states. If McGinn is correct, a full-blooded physicalism is consistent with Kripke's Cartesian intuitions regarding the non-identity of the mental and the physical. But I think McGinn is mistaken. In particular, McGinn misunderstands the nature of an "epistemic counterpart" of a token pain. So contrary to McGinn, token physicalism does not seem to be able to defend against Kripke after all.

According to the Multiple Realizability Argument, a higher-level property typically has many physical realizers, so it cannot be type-identical to any one of them. This enables the non-reductive physicalist to claim that some higher-level properties are type-distinct from physical properties. The reductive physicalist can counter with the Disjunctive Strategy: nothing prevents us from type-identifying the higher-level property with the disjunction of its realizers. Developing a powers-based ontology of properties, Shoemaker and Wilson present responses to the Disjunctive Strategy, wherein higher-level property (...) instances are token-distinct from their realizers, while instances of disjunctions are not. In this paper, I argue that such responses to the Disjunctive Strategy can be reasonably resisted, either by denying token-distinctness, or by insisting that exhaustively overlapping disjunctive properties are also token-distinct from the realizers. This secures the Disjunctive Strategy as a core component of the argument for reductive physicalism. (shrink)

In the second installment of this contribution to the Common Knowledge symposium “Contextualism—the Next Generation,” Donne's religious poetry is set in dialogue not only with the “Great Controversy” of the 1560s over the nature of the eucharistic sign but also with pre-Christian semiotic discourses. From the perspective of contextualist scholarship, which recognizes in any temporal context a limited number of discourses available, Donne's religious poems of the period from about 1607 to 1620 register many contradictory conceptions, but contradictory only in (...) the sense that no contextualist map of religious identities allows for their miscibility or even collocation. Notoriously resistant to psychological and phenomenological interests, contextualism has no place for an early seventeenth-century Christian writer whose concern is less to join a school of thought on the Real Presence in the Eucharist than to dismiss the issue as vexingly trivial in comparison with the question of whether God thinks that each or any of us adequately loves him. For the questions that concern Donne, there are no determinate answers available, and no standard vocabulary. But the poet's alternating acquiescence in and fretfulness about indeterminacy and incomprehensibility constitute an intellectual and affective identity as much as does the attachment to any one or other more recognizable set of arguments and ways of framing them.

Objections to uploading may be parsed into substrate issues, dealing with the computer platform of upload and personal identity. This paper argues that the personal identity issues of uploading are no more or less challenging than those of bodily transfer often discussed in the philosophical literature. It is argued that what is important in personal identity involves both token and type identity. While uploading does not preserve token identity, it does save type (...) class='Hi'>identity; and even qua token, one may have good reason to think that the preservation of the type is worth the cost.

The thesis that mental states are physical states enjoys widespread popularity. After the abandonment of typeidentity theories, however, this thesis has typically been framed in terms of state tokens. I argue that token states are a philosopher’s fiction, and that debates about the identity of mental and physical state tokens thus rest on a mistake.

It is often said that there are two varieties of identity theory. Type-identity theorists interpret physicalism as the claim that every property is identical to a physical property, while token-identity theorists interpret it as the claim that every particular is identical to a physical particular. The aim of this paper is to undermine the distinction between the two. Drawing on recent work connecting generalized identity to truth-maker semantics, I demonstrate that these interpretations are logically equivalent. (...) I then argue that each has the resources to resolve problems facing the other. (shrink)

Parfit argues that survival, Not identity, Is the important thing in cases of personal resurrection, Fission, Etc. I argue that parfit's and dennett's well known cases--And fantasies about cloning and telecloning--Suggest a distinction between type and token persons, Memories, Intentions, Etc. Parfit is wrong, I suggest, To think survival more determinate than identity; with quine I hold that there is no objective matter to be right or wrong about.

Homotopy Type Theory is a proposed new language and foundation for mathematics, combining algebraic topology with logic. An important rule for the treatment of identity in HoTT is path induction, which is commonly explained by appeal to the homotopy interpretation of the theory's types, tokens, and identities as spaces, points, and paths. However, if HoTT is to be an autonomous foundation then such an interpretation cannot play a fundamental role. In this paper we give a derivation of path induction, (...) motivated from pre-mathematical considerations, without recourse to homotopy theory. (shrink)

Exploring the peculiar nature of future generations and concluding that types of future people is the most promising object on which to project our concern for future generations the article poses two main questions: “Can future people have rights?” and, if so, “Do they in fact have any rights?” The article first explains why the non-existence of future people raises doubts whether future generations can have rights. Within the philosophical literature, the leading approach explaining how future people can, nevertheless, have (...) rights argues that they have rights as tokens of types of people. After presenting this account of the rights of future people and couching it in a jurisprudential context, this Article points out a possible deficiency in the approach’s metaphysical underpinnings. Assuming that future people can have rights the article goes on to explain that there is reason to doubt whether any such rights actually exist, which derive from the doubt whether future people will be harmed by most actions and choices in their prenatal past. According to what has come to be known as the “nonidentity argument,” actions and choices that are necessary parts of the causal chain leading up to the existence of a person cannot harm that person - had the act or choice not occurred that person would have never existed, and one is better off existing than not. Under the two prevalent theories of rights, the Will Theory and the Interest Theory, the nonidentity argument seemingly entails that future people have no rights. After exploring how this is the case, the conception of harm underlying the nonidentity argument is analyzed. Two types of interests future people may have in prenatal identity-determinative events (constitutive interests and threshold interests) are explored as possible sources of certain rights future people may have - the nonidentity argument notwithstanding. The article then elaborates and assesses the merits of these approaches. (shrink)

Propertarian justifications of intellectual property postulate the appropriation of various entities, often called patterns, designs, or technologies. These must be immaterial and should not be confused with material structures that embody them. Hence two classes of objects are distinguished. It is convenient to refer to them as types and tokens. The type must involve a condition defining which material structures should be considered its tokens. For an IP regime to be economically meaningful one must necessarily appropriate types in a way (...) which restricts access to wide classes of similar, non-identical material structures. Therefore, type conditions must be general. They must define, with a margin of tolerance, only certain aspects of the structure, leaving others unspecified. Consequently, the relationship between such types and tokens is of many-to-many variety. The recognition of these facts leads to four problems in justifying intellectual property on propertarian grounds. The first problem is to demonstrate possession of the type in the pre-legal situation. The second one is to explain, why boundaries of an appropriated type should be placed in a particular location. The third problem is to avoid claim deadlocks resulting from conflicts of rights generated by separate overlapping types. The fourth problem is to justify why ownership of the type should entail the control over other separate entities—that is tokens. In the propertarian framework grounded in the pre-legal state of nature, satisfactory solutions do not seem to have been proposed for any of these four problems. (shrink)

The author argues that uploading does preserve personal identity, at least identity of a certain sort. The fact that we are assuming that computers are capable of embodying all the same type of properties necessary for personal identity means that we can make use of the equivalency thesis. There are two reasons for invoking the equivalency thesis. The first is so that we are not misled by a new form of racism: substratism. The second is that it (...) makes directly relevant an enormous amount of philosophical effort that has gone into exploring the possibility of carbonto‐ carbon transfers. He examines an alternative explanation to somaticism for why people might be reluctant to use Parfit's Teletransporter, namely, fear of the unknown. Finally, the author talks about the type/token (TT) account of personal identity and then see whether the no‐branching argument has any traction against it. (shrink)

The main aim of this paper is to show that there is one version of supervenience of the mental on the physical which is entailed by token-token identity (I call this version change-supervenience); and to establish that of the other better known versions of supervenience in the literature (which I call difference-supervenience), none are so entailed. One consequence of this is that Burge's thought experiments while successful in refuting difference-supervenience cannot in themselves refute identity thesis. However, (...) the introduction of change supervenience leads me to devise an analogous thought experiment against change-supervenience, thus refuting identity thesis as well. (shrink)

Gender scholars use the metaphor of the “glass escalator” to describe a tendency for men in women-dominated workplaces to be promoted into supervisory positions. More recently, scholars, including the metaphor’s original author, critique the glass escalator metaphor for not addressing the intersections of gender with other relevant identities or the ways that work has changed in the twenty-first century. I apply an intersectional lens to understand how gender and race shape women’s career paths in tech work, where twenty-first century changes (...) to the organization of workplaces are common. I build on theories of raced and gendered labor and the glass escalator to make sense of women’s careers in a contemporary field dominated by men. I find some evidence that white women, but not women of color, experience something similar to a “glass escalator” where they are promoted into management, but those promotions are a smaller step up—more step stool than escalator. These promotions move women out of technical positions and towards business and management, releasing engineering teams from the pressure to fully incorporate women. (shrink)

The materialist thesis that there is a type-type identity between certain mental phenomena and certain physical phenomena has encountered serious criticisms. This paper is to propose a revised form of mind-body identity theory which moves forward from the token identity theory and can stand the major criticism made against the type-type identity theory. In the first part of the paper, through a very brief review of the issue I show what needs to be done; in (...) the second part, I show how my solution avoids the difficulties that have troubled the type-type identity theory.

SummaryHow can the immense amount of suffering and waste inherent in the evolutionary process be reconciled with the existence of a perfectly good and omnipotent God? A widely embraced proposal in the area of “evolutionary theodicy” is the so-called “Only Way”-argument. This argument contends that certain valuable goods – in particular, creaturely independence and human freedom – can only come about through a genuinely indeterministic and partly uncontrolled process of evolution. In a previous article, I have argued that the “Only (...) Way”-argument can be defeated by a “Twin Earth”-thought experiment: If God is omnipotent, he could have created – directly, without evolution – creatures that are molecule-for-molecule identical to those that he actually created through evolution. If the creatures that he actually created have freedom and independence, there is no valid reason to deny that the non-evolved “twin creatures” would also be free and independent. Recently, Eikrem and Søvik have suggested a way of blocking my Twin Earth-argument by appealing to the distinction between type-values and token-values. While ES admit that the Twin Earth-argument shows the non-necessity of evolution for the existence of certain type-goods, they argue that an evolutionary creation can be justified by appeal to valuable token-goods that could not have existed without evolution. In this article, I respond to ES’s token-goods argument by showing that it is incompatible with a basic presupposition of “Only Way” evolutionary theodicies, namely the claim that the evolutionary process is genuinely indeterministic and partly uncontrolled.

Two issues are raised with regard to Ted Honderich's A Theory of Determinism. First, regarding the relation between a token identity theory of mental and physical events and Honderich's ?psychoneural union theory?, it is suggested that a token identity theory would serve Honderich's purposes while securing a simpler ontology. Second, it is argued that there is a substantive philosophical issue dividing compatibilists and incompatibilists on the question of whether persons possess free will, contrary to Honderich's contention (...) that the compatibilist and incompatibilist differ only in responsive attitude.

We present a novel reductive theory of type-identity physicalism, which is inspired by the foundations of statistical mechanics as a general theory of natural kinds. We show that all the claims mounted against type-identity physicalism in the literature don’t apply to Flat Physicalism, and moreover that this reductive theory solves many of the problems faced by the various non-reductive approaches including functionalism. In particular, we show that Flat Physicalism can account for the appearance of multiple realizability in the (...) special sciences, and that it gives a novel account of the genuine autonomy of the kinds and laws in the special sciences. We further show that the thesis of genuine multiple realization, which is compatible with all forms of non-reductive approaches including functionalism, implies what we call token-dualism; namely the idea that in every token there are non-physical facts, which may either be non-physical properties or some non-physical substance. In other words, we prove that non-reductive kinds necessarily assume non-reductive tokens, i.e., token dualism. Finally, we show that all forms of non-reductive approaches including functionalism imply a literally multi-leveled structure of reality. (shrink)

Barry Dainton has developed a sophisticated version of the bundle theory of the subject of experiences. I shall focus on three claims Dainton makes: the identity-conditions of subjects can be specified in terms of capacities to produce experiences; the identity-conditions of token capacities are not determined by their subjects; and a subject is nothing over and above a bundle of such capacities. I shall argue that Dainton’s key notion of co-consciousness, a primitive relation of experienced togetherness, presupposes (...) a subject common to each of the experiences which are experienced together. Therefore, co-consciousness cannot be used to state the identity-conditions of subjects in a non-circular manner. I shall also argue that none of the different options Dainton offers for specifying the identity-conditions of token experiential capacities independently of their subjects are successful. I shall then outline a way in which this can be done, but argue that it undermines the claim that a subject is nothing over and above a bundle of such capacities. (shrink)
