Criteria of identity without sortals

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

Speech affordances: A structural take on how much we can do with our words

Individuals can do a broad variety of things with their words and enjoy different degrees of this capacity. What moderates this capacity? And in cases in which this capacity is unjustly disrupted, what is a good explanation for it? These are the questions I address here. I propose that speech capacity, understood as the capacity to do things with your words, is a structural property importantly dependent on individuals' position in a social structure. My account facilitates a non‐individualistic explanation of cases in which speech capacity is undermined due to speaker's perceived social identity, e.g. episodes of silencing. Instead of appealing to interlocutors' implicit bias against speaker's identity, a structural approach refers to the positions interlocutors occupy in the social structure and the discursive conventions operating upon those positions. I articulate my proposal drawing on the notion of affordances. Each position within a social structure is associated with its own range of speech affordances. Thus, speech capacity is a function of the probability distribution of speech affordances across positions in the structure.     

DO WE SEE APPLES AS EDIBLE?

Do we (sometimes) perceive apples as edible? One could argue that it is just a manner of speaking to say so: we do not really see an object as edible, we see it as having certain shape, size and color and we only infer on the basis of these properties that it is. I argue that we do indeed see objects as edible, and do not just believe that they are. My argument proceeds in two steps. First, I point out that Susanna Siegel's influential argument in favor of the claim that we represent sortal properties perceptually does not work. Second, I argue that we can fix this argument if we replace the sortal property in question with the property of being edible, climbable or Q‐able in general.     

Frege on identities

The idea underlying the Begriffsschrift account of identities was that the content of a sentence is a function of the things it is about. If so, then if an identity a=b is about the content of its contained terms and is true, then a=a and a=b have the same content. But they do not have the same content; so, Frege concluded, identities are not about the contents of their contained terms. The way Frege regarded the matter is that in an identity the terms flanking the symbol for identity do not have their ordinary contents, but instead have themselves as their contents. In ‘Uber Sinn und Bedeutung’ Frege became convinced that if an identity a=bis about the signs aand b, then it expresses no proper knowledge. So, since it is evident that many such identities do express proper knowledge, Frege concluded that identities are not about their contained signs. So he became convinced that his Begriffsschrift account was incorrect. What was the error in the argument that led Frege to that account? It was thinking that the content of a sentence is a function of the contents of its constituent signs, that is, the things it is about.     

Sortal concepts and causal continuity: comment of Rips, Blok, and Newman (2006)

L. J. Rips, S. Blok, and G. Newman (2006) proposed that singular concepts, which support the tracing of individual objects across their existence, are governed by a principle of causal continuity. They purported to show that causal continuity is better than existing theories at explaining judgments of the persistence of individual objects. This article makes 3 points. First, the construct of causal connectedness entails a wide variety of different explanatory factors; calling them all causal has questionable explanatory value. There is little evidence that the ultimate basis for identity judgments in many cases is causal. Second, the authors suggest that causal knowledge is indeed important to identity, but that it is important in the context of sortal concepts; different causal information matters for different kinds of things. Finally, the authors consider whether causal knowledge or sortal concepts are more fundamental to tracing individual identity, that is, whether causal knowledge is necessary for identity judgments. The authors appeal to research in developmental psychology that has begun to address this debate, supporting the primacy of sortal concepts. Although there continues to be shortcomings of all theories of object persistence, it is not clear that the causal continuer theory brings new clarity to the puzzle.     

Physicalism and the sortalist conception of objects

Many hold an Aristotelian metaphysic of objects: fundamentally, objects fall under sortals and have persistence conditions befitting their sort. Though sometimes offered as a theory of material objects, I argue this view is in fact incompatible with physicalism. Call a ‘sortal’ a kind of object, a ‘sortal identity’ a particular’s nature specified in sortal terms, and ‘sortal properties’ properties that are determined by an object’s sortal identity, such as its persistence conditions. From here the argument runs as follows. Something is physical only if it is physically fundamental or is determined by what is physically fundamental (P1), but sortal identities and properties are neither physically fundamental (P2) nor determined by the physically fundamental (P3). I defend each premise in turn. P1 falls out of the standard conception of physicalism. Rejecting P2 is tantamount to positing Aristotelian substantial forms and formal causes—which are themselves incompatible with physicalism. I defend P3 by showing that extant solutions to “the grounding problem”—the problem of showing how (nonfundamental) sortal properties are determined by (nonsortal) physical properties—are either physicalistically unacceptable, or else physicalistically acceptable but opposed to the sortalist metaphysic.     

Object Individuation in the Absence of Kind-specific Surface Features: Evidence for a Primordial Essentialist Stance?

ABSTRACT

It has been suggested that due to functional similarity, sortal object individuation might be a primordial form of psychological essentialism. For example, the relative independence of identity judgment from perceived surface features is a characteristic of essentialist reasoning. Also, infants engaging in sortal object individuation pay more attention to kind than surface feature information when judging the identity of objects (e.g.). Indeed, previous research found that 14-month-old infants can judge trans-temporal identity even in complete absence of kind-specific surface features. Here, we used another more demanding non-linguistic paradigm to test the limits of these abilities in 14-, 18-, 23- and 36-month-old infants, comparing their performance to recent great ape data. Particularly, we presented infants with two food kinds, whose surface features were then fully transformed to make them look identical. If reasoning according to essentialist principles, participants should select the preferred item despite superficial manipulations. However, only 36-month-olds reliably tracked the preferred item after superficial manipulations. This suggests that, although basic psychological essentialism may emerge early in infancy, more complex forms require domain-general cognitive prerequisites, which only develop in more protracted form.     

Analytical derivation of the effective temperature for field-dependent hopping conductivity

The electric-field enhancement of hopping conductivity in amorphous solids can be described in terms of an effective temperature T _eff given by for hopping, at a temperature T and field F, within a uniform distribution of electronic states with localization length γ^?1. We have derived this expression analytically and find at low fields a value for C of 1/2^1/2, which is consistent with the F-independent value C = 0.67 previously obtained numerically for band-tail hopping. With increasing electric field, the decrease in C(F) matches the hopping transport characteristics in amorphous semiconductors (hydrogenated amorphous silicon and hydrogenated amorphous carbon nitride) better than previous numerical simulations.     

Reticence

There is an obvious role for self‐assertion within discourse. It is much less obvious what role self‐withdrawal might play. Indeed, it is far from obvious what role it could play. For how can we enter into discourse at all if we pull ourselves from the fray? Heidegger, however, claims not only that self‐withdrawal has a role to play but that reticence is the authentic mode of discourse. In this paper, I develop an account of reticence that explains its importance to Being and Time. I argue that Heidegger's conception of reticence is central to his explanation of how the understanding can be developed in terms of the things themselves, rather than in terms of what one says about things.     

Thought and the social community

The anti‐Cartesian idea that a person's thoughts are not entirely fixed by what goes on inside that person's head is suggested by Hegel, and echoed in Wittgenstein and Frege. An argument for the view has recently been given by Tyler Burge. This paper claims that Burge's data can be explained better by an individualistic theory. The basic idea is that an individual's thoughts are specified analogically, in ordinary discourse, through the model of a language. Though the modelling‐sentences are public, the thoughts of the individual are inner states whose identity does not depend upon those sentences. They have content naturally, whether or not content happens to be ascribed to them.     

Against Probabilistic Measures of Coherence

It is shown that the probabilistic theories of coherence proposed up to now produce a number of counter-intuitive results. The last section provides some reasons for believing that no probabilistic measure will ever be able to adequately capture coherence. First, there can be no function whose arguments are nothing but tuples of probabilities, and which assigns different values to pairs of propositions {A, B} and {A, C} if A implies both B and C, or their negations, and if P(B)=P(C). But such sets may indeed differ in their degree of coherence. Second, coherence is sensitive to explanatory relations between the propositions in question. Explanation, however, can hardly be captured solely in terms of probability.     

Transcendence of the Ego (The Non-Existent Knight)

I exist, but I am not a thing among things; X exists if and only if there is something such that it=X. This is consistent, and it is a view that can be supported. Calvino’s novel The Non‐Existent Knight can be read so as to illustrate this view. But what is my relation to the things there are if I am not identical with any of them – things such as my arms, my garden, the city I live in? I name this the Gurduloo problem, after the Knight’s page. This relation must be one that admits of degrees; I suggest that we say that I manifest myself through the things thus associated with me. Several pseudo‐problems, pertaining to volitional action, supervenience, observability, and the emergence of consciousness, dissolve upon inspection.     

Two cheers for Tanhā

The central character in Sartre's 1938 novel La Nausée, Antoine Roquentin, has lost his sense of things, and now the world appears to him as utterly unstable. Roquentin suffers from what he calls ‘nausea,’ a condition caused by an ontological intuition that the self, as well as the world through which that ‘self’ moves, lacks a substantial nature. The novel portrays Sartre's own philosophical account of the self in La transcendence de l'égo. Here Sartre argues that Husserl's account of consciousness is not radical enough; the ‘I’ or ego is a pseudo-source of activity (and Sartre thus draws very close to a particularly Buddhist account of personal identity). My essay questions Roquentin's response to his ontological insight: why is this the occasion for ‘nausea’? Why doesn't Roquentin (as King Milinda famously does) celebrate and embrace his ‘non-self’? I argue that Sartre's depiction of Roquentin's ailment, and the unsatisfactory solution he provides, misunderstands both the aggregate nature of things as well as authentically rendered consciousness-only (vijñaptimātra).     

Identity Theories of Truth and the Tractatus

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 identity theory is vulnerable to a complaint of idealism that the Tractatus can deflect.     

A Modal Sortal Logic

An intensional semantic system for languages containing, in their logical syntax, sortal quantifiers, sortal identities, (second-order) quantifiers over sortals and the necessity operator is constructed. This semantics provides non-standard assignments to predicate expressions, which diverge in kind from the entities assigned to sortal terms by the same semantic system. The nature of the entities assigned to predicate expressions shows, at the same time, that there is an internal semantic connection between those expressions and sortal terms. A formal logical system is formulated that is proved to be absolutely consistent, sound and complete with respect to the intensional semantic system.     

Knowing One’s Own Self: An Analysis of Vivekananda’s Approach to One’s Identity

A successful declaration of one’s identity in saying “ahaṃ Brahmāsmi” is a result of knowing one’s own self as indistinguishable from Brahman. The non-difference between oneself and the Brahman is one’s true identity, and it goes without saying, knowledge of one’s true identity constitutes the correct knowing of one’s own self. That the said non-difference is upheld by vedānta, and we need to put this ideal non-difference into practice is the crux of Vivekananda’s practical vedānta. Vivekananda gives certain reasons for the practicability of vedānta. This paper’s part I is an exposition of Vivekananda’s practical vedānta, focussing on those reasons for practical vedānta and orienting each towards an analytical understanding. In part II, a linguistic analysis of Vivekananda’s approach to one’s identity has been carried out after introducing J. Hintikka’s interpretation of Descartes’ “I think, therefore, I am” and G. Misra’s interpretation of sat (existence, reality or being) cit (consciousness, knowledge or cognition) ānanda (bliss, intense happiness or felicity). The latter’s interpretation displays a positivist’s linguistic analysis of vedānta, whereas the former’s does a speech act theorist’s analysis of Descartes’ cogito principle. The present analysis indicates that practical vedānta can be read in the light of analytic philosophy and Vivekananda’s approach to one’s identity can be understood in terms of speech acts.

     

Should We Want God to Exist?

Whether God exists is a metaphysical question. But there is also a neglected evaluative question about God’s existence: Should we want God to exist? Very many, including many atheists and agnostics, appear to think we should. Theists claim that if God didn’t exist things would be far worse, and many atheists agree; they regret God’s inexistence. Some remarks by Thomas Nagel suggest an opposing view: that we should want God not to exist. I call this view anti‐theism. I explain how such view can be coherent, and why it might be correct. Anti‐theism must be distinguished from the argument from evil or the denial of God’s goodness; it is a claim about the goodness of God’s existence. Anti‐theists must claim that it’s a logical consequence of God’s existence that things are worse in certain respects. The problem is that God’s existence would also make things better in many ways. Given that God’s existence is likely to be impersonally better overall, anti‐theists face a challenge similar to that facing nonconsequentialists. I explore two ways of meeting this challenge.     

Identity in Fiction

Anthony Everett ( 2005 ) argues that those who embrace the reality of fictional entities run into trouble when it comes to specifying criteria of character identity. More specifically, he argues that realists must reject natural principles governing the identity and distinctness of fictional characters due to the existence of fictions which leave it indeterminate whether certain characters are identical and the existence of fictions which say inconsistent things about the identities of their characters. Everett's critique has deservedly drawn much attention and a number of defensive moves have been made by, or on the behalf of, fictional realists. My goal in this paper is to move this debate on a further step. I have three goals: (i) to clarify the importance of Everett's discussion of identity criteria within the context of fictional realism, (ii) to reassess Everett's objections to realism in light of the resultant literature, and (iii) to develop a novel strategy for responding to Everett's concerns. On the approach to be developed, the problems emerge due to an indeterminacy inherent in the concept of a fictional character itself.     

Identity,Individuation and Substance

The paper takes off from the problem of finding a proper content for the relation of identity as it holds or fails to hold among ordinary things or substances. The necessary conditions of identity are familiar, the sufficient conditions less so. The search is for conditions at once better usable than the Leibnizian Identity of Indiscernibles (independently suspect) and strong enough to underwrite all the formal properties of the relation. It is contended that the key to this problem rests at the level of metaphysics and epistemology alike with a sortalist position. Sortalism is the position which insists that, if the question is whether a and b are the same, it has to be asked what are they? Any sufficiently specific answer to that question will bring with it a principle of activity or functioning and a mode of behaviour characteristic of some particular kind of thing by reference to which questions of persistence or non‐persistence through change can be adjudicated. These contentions are illustrated by reference to familiar examples such as the human zygote, the Ship of Theseus and Shoemaker's Brown‐Brownson. The first example is hostage for a mass of unproblematical cases. The problems presented by the second and third sort of examples arise chiefly (it is claimed) from an incompleteness in our conceptions of the relevant sort—the what the thing in question is. That incompleteness need not prevent us from knowing perfectly well which thing we are referring to. In the concluding section, sortalism is defended against various accusations of anthropocentrism. The paper touches on the interpretation of Heraclitus, Leibniz's theory of clear indistinct ideas, the difficulties of David Lewis's ‘perdurantist’ or stroboscopic view of persistence, four‐dimensionalism, and the relation of personal identity both to experiential memory and to the particular bodily physiognomy of a subject. At some points—as in connection with the so‐called Only a and b rule—the paper corrects, supplements or extends certain theses or formulations proposed in the author's Sameness and Substance Renewed (2001).     

The Love Affair between Philosophy and Poetry: Aristotle's Poetics and Narrative Identity

In order to grasp the distinctive character of the object imitated in tragedies, Aristotle's Poetics introduces a new notion of action (praxis), which does not refer to individual ethical deeds as in the Ethics. Rather, it signifies a whole with a beginning, a middle, and an end, whose constitutive components are events (pragmata). This paper argues that the notion of agents undergoes a parallel transformation in the treatise on poetry. It no longer refers exclusively to the authors of ethical deeds, but to the characters who enact the entire dramatic action (prattontes). Their nature can be understood in terms of a potential story whose logos (account, articulation) is a muthos (story, narrative). On this ground, the suggestion is made that the Poetics provides the elements of a narrative conception of human identity.
