Quasi Indexicals

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence ϕ allows for cases in which one party utters ϕ and the other its negation, and neither party's claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other's claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the parties to reject each other's claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. The existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well.     

索引词及其语义——兼谈汉语中的“我”和“自己”

索引词不同于专名和限定描述语,因此需要一个专门的语义理论对其进行解释。本文首先介绍了索引词的经典解释理论——Kaplan([15])的二维语义论,然后考察了反驳Kaplan理论的四类反例:(a)"only"辖域中受宽松约束的"Ⅰ";(b)第一人称涉己信念报告;(c)转换索引词;(d)延指现象。综合这四类反例的最新研究成果,我们得出的结论是:这些反例不足以否定Kaplan关于索引词直接指称的论断,但Kaplan所否认的"怪兽"确实是存在的。基于此,我们指出需要进一步研究的问题,并在文末从索引词研究的角度探讨了汉语中的"我"和"自己"。     

From Experience to Metaphysics: On Experience‐based Intuitions and their Role in Metaphysics

Metaphysical theories are often counter‐intuitive. But they also often are strongly supported and motivated by intuitions. One way or another, the link between intuitions and metaphysics is a strong and important one, and there is hardly any metaphysical discussion where intuitions do not play a crucial role. In this article, I will be interested in a particular kind of such intuitions, namely those that come, at least partly, from experience. There seems to be a route from experience to metaphysics, and this is the core of my interest here. In order to better understand such ‘arguments from experience’ and the kind of relationship there is between this type of intuitions and metaphysical theories, I shall examine four particular cases where a kind of experience‐based intuition seems to motivate or support a metaphysical theory. At the end of the day, I shall argue that this route is a treacherous one, and that in all of the four cases I shall concentrate on, phenomenological considerations are in fact orthogonal to the allegedly ‘corresponding’ metaphysical claims. An anti‐realist view of metaphysics will emerge.     

The impurity of “pure” indexicals

Within the class of indexicals, a distinction is often made between “pure” or “automatic” indexicals on one hand, and demonstratives or “discretionary” indexicals on the other. The idea is supposed to be that certain indexicals refer automatically and invariably to a particular feature of the utterance context: ‘I’ refers to the speaker, ‘now’ to the time of utterance, ‘here’ to the place of utterance, etc. Against this view, I present cases where reference shifts from the speaker, time, or place of utterance to some other object, time, or place. I consider and reject the claim that these counterexamples to the automatic indexical theory all involve non-literal uses of indexicals and argue that they cannot be explained away on the grounds that they involve conversational implicature or pretense.     

‘I’

It has traditionally been maintained that every token of ‘I’ refers to its utterer. However, certain uses of indexicals conflict with this claim, and its counterparts with respect to ‘here’ and ‘now’, suggesting that the traditional account of indexical reference should be abandoned. In this paper, I examine some proposed alternatives and the difficulties they face, before offering a new account of indexical reference. I endorse Kaplan’s view that the reference of an indexical is determined on any occasion it is used by applying its character to a particular context, arguing that the problem cases show that this is not always the context of utterance. The task facing the semantic theorist is thus to explain what fixes the reference-determining context. I consider and reject both Predelli’s suggestion that the reference-determining context is the one intended by the utterer, and Corazza et al.’s proposal that the relevant context is fixed by conventions delivered by the utterance setting. The discussion of these two accounts reveals that an adequate theory of indexical reference should allow the speaker to use indexicals in novel ways, whilst holding that what a speaker can refer to with an indexical utterance is constrained by what an audience can understand. I develop an account based around these two requirements.     

Smith on Indexicals

In this paper, I advance a new view of the semantics of indexicals, using a paper by Quentin Smith as my starting point. I make use of Smith’s examples, refined and expanded upon by myself to argue, as Smith does, that the standard view, that indexicals refer to some prominent features of the context according to an invariant rule called the character, does not agree with a wide range of phenomena. I depart from Smith, however, in denying that we need more complex rules, which he does not give, called metacharacters to account for all the deviations, and instead argue for a view of indexicals as just being special cases of demonstratives. I show how demonstratives can be substituted for indexicals to support this view, and I adduce recent work in the semantics of demonstratives to explain how it can work.     

Can Pragmatists Be Moderate?

In discussions of whether and how pragmatic considerations can make a difference to what one ought to believe, two sets of cases feature. The first set, which dominates the debate about pragmatic reasons for belief, is exemplified by cases of being financially bribed to believe (or withhold from believing) something. The second set, which dominates the debate about pragmatic encroachment on epistemic justification, is exemplified by cases where acting on a belief rashly risks some disastrous outcome if the belief turns out to be false. Call those who think that pragmatic considerations make a difference to what one ought to believe in the second kind of case, but not in the first, ‘moderate pragmatists’. Many philosophers – in particular, most advocates of pragmatic and moral encroachment – are moderate pragmatists. But moderate pragmatists owe us an explanation of exactly why the second kind of pragmatic consideration makes a difference, but the first kind doesn’t. I argue that the most promising of these explanations all fail: they are either theoretically undermotivated, or get key cases wrong, or both. Moderate pragmatism may be an unstable stopping point between a more extreme pragmatism, on one hand, and an uncompromising anti-pragmatism on the other.     

Narratives,mechanisms and progress in historical science

Geologists, Paleontologists and other historical scientists are frequently concerned with narrative explanations targeting single cases. I show that two distinct explanatory strategies are employed in narratives, simple and complex. A simple narrative has minimal causal detail and is embedded in a regularity, whereas a complex narrative is more detailed and not embedded. The distinction is illustrated through two case studies: the ‘snowball earth’ explanation of Neoproterozoic glaciation and recent attempts to explain gigantism in Sauropods. This distinction is revelatory of historical science. I argue that at least sometimes which strategy is appropriate is not a pragmatic issue, but turns on the nature of the target. Moreover, the distinction reveals a counterintuitive pattern of progress in some historical explanation: shifting from simple to complex. Sometimes, historical scientists rightly abandon simple, unified explanations in favour of disunified, complex narratives. Finally I compare narrative and mechanistic explanation, arguing that mechanistic approaches are inappropriate for complex narrative explanations.     

Constructivism, the so-called semantic learning theories, and situated cognition versus the psychological learning theories

In this paper, the perspective of situated cognition, which gave rise both to the pragmatic theories and the so-called semantic theories of learning and has probably become the most representative standpoint of constructivism, is examined. We consider the claim of situated cognition to provide alternative explanations of the learning phenomenon to those of psychology and, especially, to those of the symbolic perspective, currently predominant in cognitive psychology. The level of analysis of situated cognition (i.e., global interactive systems) is considered an inappropriate approach to the problem of learning. From our analysis, it is concluded that the pragmatic theories and the so-called semantic theories of learning which originated in situated cognition can hardly be considered alternatives to the psychological learning theories, and they are unlikely to add anything of interest to the learning theory or to contribute to the improvement of our knowledge about the learning phenomenon.     

Pragmatism and Philosophy of Science: A Critical Survey

After delineating the distinguishing features of pragmatism, and noting the resources that pragmatists have available to respond effectively as pragmatists to the two major objections to pragmatism, I examine and critically evaluate the various proposals that pragmatists have offered as a solution to the problem of induction, followed by a discussion of the pragmatic positions on the status of theoretical entities. Thereafter I discuss the pragmatic posture toward the nature of explanation in science. I conclude that pragmatism has (a) a generally compelling solution to Hume’s problem of induction; (b) no specific position on the status of theoretical entities, although something like the non‐realism of the sort developed by van Fraassen seems a defensible candidate for most pragmatists in general, even though there are non‐trivial objections to van Fraassen’s position; and (c) central to the pragmatic conception of scientific explanation is the abandonment of our common conception of truth as a necessary condition for sentences to provide adequate explanations, and a drift in the direction of a contextualist account of explanation.     

Resolving arguments by different conceptual traditions of realization

There is currently a significant amount of interest in understanding and developing theories of realization. Naturally arguments have arisen about the adequacy of some theories over others. Many of these arguments have a point. But some can be resolved by seeing that the theories of realization in question fall under different conceptual traditions with different but compatible goals. The arguments I will discuss fit a general pattern. A philosopher argues that one theory of realization is better than another because it provides a better explanation for a particular range of phenomena, say, accounting for common sense cases, or cases within the sciences, when in fact the theories in question are not genuine competitors. I will first describe three different conceptual traditions that are implicated by the arguments under discussion. I will then examine the arguments, from an older complaint by Norman Malcolm against a familiar functional theory to a recent argument by Thomas Polger against an assortment of theories that traffic in inherited causal powers, showing how they can be resolved by situating the theories under their respective conceptual traditions.     

Einstein's theory of theories and types of theoretical explanation

In this paper I draw on Einstein's distinction between “principle” and “constructive” theories to isolate two levels of physical theory that can be found in both classical and (special) relativistic physics. I then argue that when we focus on theoretical explanations in physics, i.e. explanations of physical laws, the two leading views on explanation, Salmon's “bottom‐up” view and Kitcher's “top‐down” view, accurately describe theoretical explanations for a given level of theory. I arrive at this conclusion through an analysis of explanations of mass—energy equivalence in special relativity.     

Weak coherence,no theory of mind,or executive dysfunction? Solving the puzzle of pragmatic language disorders

Deficits in pragmatic language ability are common to a number of clinical populations, for example, right-hemisphere damage (RHD), Autism and traumatic brain injury (TBI). In these individuals the basic structural components of language may be intact, but the ability to use language to engage socially is impaired. Despite the nature of these difficulties being well documented, exactly what causes these difficulties is less clear. Furthermore, the current status of causal explanations for pragmatic difficulties across these populations is divergent and sometimes contradictory. This paper explores the empirical validity of three theories that attempt to explain pragmatic language impairment. It is recommended that a new, more convergent approach to investigating the causes of pragmatic language disability be adopted.     

Coercion and pragmatic presuppositions

In Category Mistakes, Magidor proposes that sortal restrictions should be viewed as pragmatic presuppositions. This contrasts with recent linguistic theories of successfully resolved category mistakes, e.g. coercions or copredication. It has been argued that for the proper treatment of such examples, sortal restrictions should be expressed by semantic presuppositions since they need to interact with compositional semantics. I explore possible ways in which Magidor’s theory could be extended to explain examples of coercion and copredication. The outcome of the discussion is that incorporation of these facts into Magidor’s pragmatic system might be possible, but ecessitates choices that are far from trivial.     

Rehabilitating Warranted Assertibility: Moral Inquiry and the Pragmatic Basis of Objectivity

This article defends a pragmatic conception of objectivity for the moral domain. I begin by contextualizing pragmatic approaches to objectivity and discuss at some length one of the most interesting proposals in this area, Cheryl Misak's conception of pragmatic objectivity. My general argument is that in order to defend a pragmatic approach to objectivity, the pragmatic stance should be interpreted in more radical terms than most contemporary proposals do. I suggest in particular that we should disentangle objectivity from truth, and I claim that moral inquiry is in most cases responsive to a normative standard that is closer to warranted assertibility than to truth. Using an argument that relies partly on Huw Price's account of forms of normative assertion, I will show that a practice‐based account of warranted assertibility does the epistemic work required to defend objectivity while avoiding exposure to the criticisms that are usually addressed against this notion.     

Ethicist as Designer: A Pragmatic Approach to Ethics in the Lab

Contemporary literature investigating the significant impact of technology on our lives leads many to conclude that ethics must be a part of the discussion at an earlier stage in the design process i.e., before a commercial product is developed and introduced. The problem, however, is the question regarding how ethics can be incorporated into an earlier stage of technological development and it is this question that we argue has not yet been answered adequately. There is no consensus amongst scholars as to the kind of ethics that should be practiced, nor the individual selected to perform this ethical analysis. One school of thought holds that ethics should have pragmatic value in research and design and that it should be implemented by the (computer) engineers and/or (computer) scientists themselves, while another school of thought holds that ethics need not be so pragmatic. For the latter, the ethical reflection can aim at a variety of goals, and be carried out by an ethicist. None of the approaches resulting from these lines of thinking have been adopted on a wide-scale basis. To that end, the approach presented here is intended to bridge the gap between these schools of thought. It is our contention that ethics ought to be pragmatic and to provide utility for the design process and we maintain that adequate ethical reflection, and all that it entails, ought to be conducted by an ethicist. Thus, we propose a novel role for the ethicist—the ethicist as designer—who subscribes to a pragmatic view of ethics in order to bring ethics into the research and design of artifacts—no matter the stage of development. In this paper we outline the series of steps that a pragmatic value analysis entails: uncovering relevant values, scrutinizing these values and, working towards the translation of values into technical content. In conclusion, we present a list of tasks for the ethicist in his/her role as designer on the interdisciplinary team.     

Intentional concepts in cognitive neuroscience

In this article, I develop an account of the use of intentional predicates in cognitive neuroscience explanations. As pointed out by Maxwell Bennett and Peter Hacker, intentional language abounds in neuroscience theories. According to Bennett and Hacker, the subpersonal use of intentional predicates results in conceptual confusion. I argue against this overly strong conclusion by evaluating the contested language use in light of its explanatory function. By employing conceptual resources from the contemporary philosophy of science, I show that although the use of intentional predicates in mechanistic explanations sometimes leads to explanatorily inert claims, intentional predicates can also successfully feature in mechanistic explanations as tools for the functional analysis of the explanandum phenomenon. Despite the similarities between my account and Daniel Dennett's intentional-stance approach, I argue that intentional stance should not be understood as a theory of subpersonal causal explanation, and therefore cannot be used to assess the explanatory role of intentional predicates in neuroscience. Finally, I outline a general strategy for answering the question of what kind of language can be employed in mechanistic explanations.     

The fitting resolution of anger
