This dissertation is concerned with the problem of giving a correct account of the semantics of vague predicates such as '...is tall', '...is bald' and '...is near...'. ;In Chapter 1 I present a definition of vagueness that aims to capture, in a useful form, all our fundamental intuitions about the vagueness of predicates such as those mentioned above; such a definition is lacking in the literature. I also present an abstract characterisation of the Sorites paradox: one that is independent of (...) the particular forms in which the paradox may be presented, and brings to light the essence of the paradox. ;In Chapter 2 I examine existing theories of vagueness. In light of the definition of vagueness defended in Chapter 1, I argue that we need a semantics for vague language that countenances degrees of truth. I distinguish two sorts of degree theory. One sort---which includes the degree form of supervaluation semantics---sees vagueness as an essentially semantic matter. The other sort---which includes accounts based on fuzzy set theory---accounts for vagueness in language in terms of vagueness in the world. I argue that we need a degree theory of the latter, worldly sort. ;In Chapter 3 I examine the fuzzy theory in detail. I show that many of the objections to the fuzzy view that have been raised in the literature do not carry weight. In particular, I defend the coherence of the idea of degrees of truth. However, I isolate a problem for the fuzzy view---the problem of higher-order vagueness---that is serious enough to render the view unacceptable. ;In Chapter 4 I present a new theory of vagueness: one that is intended to share the advantages of the fuzzy view, while avoiding its disadvantages. In particular, this theory accommodates the phenomenon of higher-order vagueness. The theory involves degrees of truth, but they are not the same as the degrees of truth involved in the fuzzy theory. Although the theory involves a non-classical semantics for vague language, this semantics validates classical logic. (shrink)

Ingarden distinguishes four strata making up the structure of the literary work of art: the stratum of word sounds and sound-complexes; the stratum of meaning units; the stratum of represented objectivities (characters, actions, settings, and so forth); and the stratum of schematized aspects (perspectives under which the represented objectivities are given to the reader). It is not only works of literature which manifest this four-fold structure but also certain borderline cases such as newspaper articles, scientific works, biographies, and so forth. (...) Ingarden specifies what is characteristic of a work of literature by asserting that all declarative sentences appearing in the stratum of meaning units of such work possess what he calls a quasi-judgmental character. We discuss here Ingarden’s theory of quasi-judgments and draw out its implication that all works of literature are works of fiction through and through. (shrink)

For all the talk there has been lately about privilege, few have commented on the moral obligations that are associated with having privilege. Those who have commented haven't gone much beyond the idea that the privileged should be conscious of their privilege, should listen to those who don't have it. Here we want to go further, and build an account of the moral obligations of those with a particular kind of privilege: race privilege. In this paper we articulate an understanding (...) of race privilege, say how a person can know when she has it, and argue that a race-privileged person has obligations to offset her privilege. We make concrete suggestions for how she can, at least approximately, do this. We use particular racial group disparities in the United States as our running example throughout the paper, although our conclusions generalize. (shrink)

This essay introduces a running symposium on the work of Richard Rorty and its legacy fifteen years after his passing. The arc of Rorty's thought defines a trajectory through American pragmatism, tracing a variation unimagined until he expressed it. His work raised Anglophone philosophers’ interest in American pragmatism as never before and also focused the interest of the whole world on American pragmatism as never before, even though the result was to define a pragmatism saturated with nominalism and suppressing the (...) most original qualities of the sources that he celebrated.

Nicholas D. Smith considers an original interpretation of the Republic, presenting it as a work about knowledge and education. Smith pays particular attention to Plato's use of images as representations of higher realities in education, as well as the power of knowledge in the Republic.

In this paper I present a new argument against vague identity — one that is more fundamental than existing arguments — and I also try to explain why we find the idea of vague identity puzzling, in a way that will dispel the puzzlement. In brief, my argument is this: to make clear sense of something, one must at least model it set-theoretically; but due to the special place of identity in set-theoretic models, any vague relation that one does model (...) set-theoretically will not be identity, for real identity will already be there, built into the background of the model, and perfectly precise.

This paper defends the idea that there might be vagueness or indeterminacy in the world itself--as opposed to merely in our representations of the world--against the charges of incoherence and unintelligibility. First we consider the idea that the world might contain vague properties and relations ; we show that this idea is already implied by certain well-understood views concerning the semantics of vague predicates (most notably the fuzzy view). Next we consider the idea that the world might contain vague objects (...) ; we argue that an object is indeterminate in a certain respect (colour, size, etc.) just in case it is a borderline case of a maximally specific colour (size, etc.) property. Finally we consider the idea that the world as a whole might be indeterminate; we argue that the world is indeterminate just in case it lacks a determinate division into determinate objects.

This book studies the diverse societies, cities, nations, economies, and regions of the Americas as they emerged in the Western hemisphere in the nineteenth and twentieth centuries. Drawing on the paradigms of social imaginaries and civilizational analysis, it explores regions of Central America, the Caribbean, the United States, and Latin America.

This paper presents and defends a definition of vagueness, compares it favourably with alternative definitions, and draws out some consequences of accepting this definition for the project of offering a substantive theory of vagueness. The definition is roughly this: a predicate 'F' is vague just in case for any objects a and b, if a and b are very close in respects relevant to the possession of F, then 'Fa' and 'Fb' are very close in respect of truth. The definition (...) is extended to cover vagueness of many-place predicates, of properties and relations, and of objects. Some of the most important advantages of the definition are that it captures the intuitions which motivate the thought that vague predicates are tolerant, without leading to contradiction, and that it yields a clear understanding of the relationships between higher-order vagueness, sorites susceptibility, blurred boundaries, and borderline cases. The most notable consequence of the definition is that the correct theory of vagueness must countenance degrees of truth. (shrink)

A clearly written, authoritative introduction to Taylor's work.

: In the epistemology of the late Wittgenstein, a central place is given to the notion of the hinge: an arational commitment that provides a foundation of some sort for the rest of our beliefs. Quasi-fideism is an approach to the epistemology of religion that argues that religious belief is on an epistemic par with other sorts of belief inasmuch as religious and non-religious beliefs all rely on hinges. I consider in this paper what it takes to find the appropriate (...) hinge for a quasi-fideist approach to the epistemology of religion. (shrink)

I argue that inquiry can be defined without reference to the attitudes inquirers have during inquiry. Inquiry can instead be defined by its aim: it is the activity that has the aim of answering a question. I call this approach to defining inquiry a “naive” account. I present the naive account of inquiry in contrast to a prominent contemporary account of inquiry most notably defended by Jane Friedman. According to this view of inquiry, which I call an attitude-centric view, inquiry (...) is appropriately defined not by the aim of the activity but by the attitudes that inquirers have during inquiry. After developing the naive view, I defend it against the objection that it collapses into the attitude-centric view. (shrink)

The philosopher Jerry Fodor was a key figure alongside Noam Chomsky in the revolution that led to the renaissance of the cognitive sciences from around 1960. This chapter describes key difference between Chomsky and Fodor. It focuses on Chomsky's and Fodor's conceptions of modularity. The chapter discusses two ways of understanding Chomsky's proposal, in particular how it claims an underlying faculty is related to processing and performance. Chomsky is largely agnostic on this question; the commitments of his programme are to (...) be found elsewhere. The most persuasive evidence for Fodorian modules, as for Chomskyan faculties, comes from dissociations. The chapter also reviews the evidential foundation of all versions of modularity: double dissociation (impairments of one or more mental abilities caused by accidents or other pathology which leave other abilities intact).

In VAGUENESS AND DEGREES OF TRUTH, Nicholas Smith develops a new theory of vagueness: fuzzy plurivaluationism. -/- A predicate is said to be VAGUE if there is no sharply defined boundary between the things to which it applies and the things to which it does not apply. For example, 'heavy' is vague in a way that 'weighs over 20 kilograms' is not. A great many predicates -- both in everyday talk, and in a wide array of theoretical vocabularies, (...) from law to psychology to engineering -- are vague. -/- Smith argues, based on a detailed account of the defining features of vagueness, that an accurate theory of vagueness must involve the idea that truth comes in degrees. The core idea of degrees of truth is that while some sentences are true and some are false, others possess intermediate truth values: they are truer than the false sentences, but not as true as the true ones. Degree-theoretic treatments of vagueness have been proposed in the past, but all have encountered significant objections. In light of these, Smith develops a new type of degree theory. Its innovations include a definition of logical consequence that allows the derivation of a classical consequence relation from the degree-theoretic semantics, a unified account of degrees of belief and their relationships with degrees of truth and subjective probabilities, and the incorporation of semantic indeterminacy -- the view that vague statements need not have unique meanings -- into the degree-theoretic framework. -/- As well as being essential reading for those working on vagueness, Smith's book provides an excellent entry-point for newcomers to the area -- both from elsewhere in philosophy, and from computer science, logic and engineering. It contains a thorough introduction to existing theories of vagueness and to the requisite logical background. (shrink)

In this paper, I explore our common-sense thinking about the relation between moral value, moral merit, and well-being. Starting from Ross’s observation that welfarist axiologies ignore our intuitions about desert, I focus on axiologies that take moral merit and well-being to be independent determinants of value. I distinguish three ways in which these axiologies can be formulated, and I then consider their application to the issue of punishment. The objection that they recommend penalties in circumstances in which intuitively we would (...) judge them to be unjustified is examined, and I suggest that it can be met by incorporating temporal information into the way in which value, well-being and moral merit are linked.

This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

I argue that the epistemology underlying Cornelius Van Til’s presuppositional apologetic methodology is quasi-fideist. According to this view, the rationality of religious belief is dependent on absolutely certain ungrounded grounds, called hinges. I further argue that the quasi-fideist epistemology of presuppositional apologetics explains why Van Til’s method is neither fideist nor problematically circular: hinges are rational in the sense that they are partly constitutive of rationality, and all beliefs (not just religious ones) depend on hinges. In addition, it illuminates something (...) of why it may strike one as a misguided or uncompelling apologetic method: instead of starting by tackling the comparatively minor epistemic commitments of the nonbeliever, it directly approaches their deepest and surest commitments.

The ‘interpretive turn’ in twentieth-century hermeneutics rests on the general ontological claim that human reality is the reality of self-interpreting animals. But under the circumstances of advanced modernity, there are aspects of human life, or spheres of human thought and action, that appear to contradict this general thesis, in that they do not present themselves as the doings of self-interpreting animals at all. Of these, the predominant one is the sphere of work or 'productive' action. In face of historical circumstances (...) in which work presents itself as bereft of the meanings that concern self-interpreting animals, hermeneutic philosophy faces a choice: Does it exempt work from the realm of self-interpretive activity, making it an exception to the general ontological thesis; or does it seek to retrieve the hermeneutic provenance of productive action? With a focus on the writings of Gadamer and Ricoeur, the chapter shows that philosophical hermeneutics has vacillated on this issue and it suggests that retrieval of the self-interpretive dimension of productive action is a central task for hermeneutics today.

The received model of degrees of belief represents them as probabilities. Over the last half century, many philosophers have been convinced that this model fails because it cannot make room for the idea that an agent’s degrees of belief should respect the available evidence. In its place they have advocated a model that represents degrees of belief using imprecise probabilities (sets of probability functions). This paper presents a model of degrees of belief based on Dempster–Shafer belief functions and then presents (...) arguments for belief functions over imprecise probabilities as a model of evidence-respecting degrees of belief. The arguments cover three kinds of issue: theoretical virtues (simplicity, interpretability and flexibility); motivations; and problem cases (dilation and belief inertia). (shrink)

A number of authors have noted that vagueness engenders degrees of belief, but that these degrees of belief do not behave like subjective probabilities. So should we countenance two different kinds of degree of belief: the kind arising from vagueness, and the familiar kind arising from uncertainty, which obey the laws of probability? I argue that we cannot coherently countenance two different kinds of degree of belief. Instead, I present a framework in which there is a single notion of degree (...) of belief, which in certain circumstances behaves like a subjective probability assignment and in other circumstances does not. The core idea is that one’s degree of belief in a proposition P is one’s expectation of P’s degree of truth. (shrink)

Our understanding of communication and its evolution has advanced significantly through the study of simple models involving interacting senders and receivers of signals. Many theorists have thought that the resources of mathematical information theory are all that are needed to capture the meaning or content that is being communicated in these systems. However, the way theorists routinely talk about the models implicitly draws on a conception of content that is richer than bare informational content, especially in contexts where false content (...) is important. This article shows that this concept can be made precise by defining a notion of functional content that captures the degree to which different states of the world are involved in stabilizing senders’ and receivers’ use of a signal at equilibrium. A series of case studies is used to contrast functional content with informational content, and to illustrate the explanatory role and limitations of this definition of functional content. _1_ Introduction _2_ Modelling Framework _3_ Two Kinds of Content _3.1_ Informational content _3.2_ Functional content _4_ Cases _4.1_ Case 1: Simplest case _4.2_ Case 2: Partial pooling _4.3_ Case 3: Bottleneck _4.4_ Case 4: Partial common interest _4.5_ Case 5: Deception _4.6_ Case 6: A further problem arising from divergent interests _5_ Discussion Appendix.

One of the most striking differences between Frege's Begriffsschrift (logical system) and standard contemporary systems of logic is the inclusion in the former of the judgement stroke: a symbol which marks those propositions which are being asserted , that is, which are being used to express judgements . There has been considerable controversy regarding both the exact purpose of the judgement stroke, and whether a system of logic should include such a symbol. This paper explains the intended role of the (...) judgement stroke in a way that renders it readily comprehensible why Frege insisted that this symbol was an essential part of his logical system. The key point here is that Frege viewed logic as the study of inference relations amongst acts of judgement , rather than – as in the typical contemporary view – of consequence relations amongst certain objects (propositions or well-formed formulae). The paper also explains why Frege's use of the judgement stroke is not in conflict with his avowed anti-psychologism, and why Wittgenstein's criticism of the judgement stroke as 'logically quite meaningless' is unfounded. The key point here is that while the judgement stroke has no content , its use in logic and mathematics is subject to a very stringent norm of assertion. (shrink)

I have argued for a picture of decision theory centred on the principle of Rationally Negligible Probabilities. Isaacs argues against this picture on the grounds that it has an untenable implication. I first examine whether my view really has this implication; this involves a discussion of the legitimacy or otherwise of infinite decisions. I then examine whether the implication is really undesirable and conclude that it is not.

This paper addresses a worry about backwards time travel. The worry is that there is something mysteriously inexplicable about the combination of commonplace events that will inevitably conspire to prevent the time traveler from doing something impossible such as killing her younger self. The worry is first distinguished from other problems for backwards time travel concerning its alleged impossibility or improbability. It is then shown that the worry is misplaced: there is in fact no real problem here. Yet the worry (...) has been widely expressed—so a suggestion is also made as to why it is so easy to get into the position of thinking that there is a genuine problem here, when in fact there is not. Finally, in light of the resolution of the inexplicability worry, a new way of dealing with the other two problems for backwards time travel—concerning its alleged impossibility and improbability—is proposed. (shrink)

The so-called paradoxes of time travel have played a significant role in both the physics and philosophy literatures - but how much force do these alleged paradoxes really have?

In his writings Jim Marshall has helpfully emphasized such Wittgensteinian themes as the multiplicity of language games, the deconstruction of ‘certainty,’ and the contexts of power that underlie discursive systems. Here we focus on another important legacy of Wittgenstein's thinking: his insistence that human activity is rule‐governed. This idea foregrounds looking carefully at the world of education and learning, as against the empirical search for new psychological or other facts. It reminds us that we need to consider, in Peter Winch's (...) words, ‘what it makes sense to say’ about certain educational phenomena, and how these meanings stand against understanding a wider form of life. This insight has important implications for doing educational research, and we examine some of these. (shrink)

If we think, as Ramsey did, that a degree of belief that P is a stronger or weaker tendency to act as if P, then it is clear that not only uncertainty, but also vagueness, gives rise to degrees of belief. If I like hot coffee and do not know whether the coffee is hot or cold, I will have some tendency to reach for a cup; if I like hot coffee and know that the coffee is borderline hot, I (...) will have some tendency to reach for a cup. Suppose that we take degrees of belief arising from uncertainty to obey the laws of probability and that we model vagueness using degrees of truth. We then encounter a problem: it does not look as though degrees of belief arising from vagueness should obey the laws of probability. One response would be to countenance two different sorts of degrees of belief: degrees of belief arising from uncertainty, which obey the laws of probability; and degrees of belief arising from vagueness, which obey a different set of laws. I argue, however, that if a degree of belief that P is a stronger or weaker tendency to act as if P, then this option is not open. Instead, I propose an account of the behaviour of degrees of belief that integrates subjective probabilities and degrees of truth. On this account, degrees of belief are expectations of degrees of truth. The account explains why degrees of belief behave in accordance with the laws of probability in cases involving only uncertainty, while also allowing degrees of belief to behave differently in cases involving only vagueness, and in mixed cases involving both uncertainty and vagueness. Justifications of the account are given both via Dutch books and in terms of epistemic accuracy. (shrink)

Part of The Blackwell Readings in Philosophy Series, this survey of ancient philosophy explores the scope of ancient philosophy, focusing on the key philosophers and their texts, examining how the foundations of philosophy as we know it were laid.

This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

This text argues that Husserl’s late philosophy of temporal and bodily subjectivity can only be understood by means of the interplay between different reductions. For various reasons, this decisive methodological aspect has been largely overlooked by most interpreters. As a consequence, the co-originality of the constitution of space and time, which first enables a comprehensive grasp of the originary processes in the living streaming present, has remained virtually unknown. This also means that the proper understanding of egology and intersubjectivity has (...) been obfuscated. It is only by bringing out the bodily and temporal foundations of the lebendige Gegenwart as presented in the C-manuscripts that Husserl’s investigations of constitutive intersubjectivity in other texts can ultimately be clarified. Notably this calls for a renewed understanding of the role of Vergegenwärtigung, showing that the community of streams, not located in my ego but precisely in a manifold of streaming living presents, are united by means of an “intersubjective association”. The problem of the individualization of the “intersubjective streaming being” that characterizes the monadic totality here finds its solution, by means of a ceaselessly ongoing and self-altering duplicity that accounts for my pre-identity at the deepest genetic level.

The overall goal of the approach developed in this paper is to estimate the likelihood of a given kinetic kill scenario between hostile spacebased adversaries using the mathematical framework of Complex Conceptual Spaces Single Observation. Conceptual spaces are a cognitive model that provide a method for systematically and automatically mimicking human decision making. For accurate decisions to be made, the fusion of both hard and soft data into a single decision framework is required. This presents several challenges to this data (...) fusion framework. The first is the challenge involved in handling multiple complex terminologies, which is addressed by drawing on a set of Space Domain Ontologies. Another challenge is the complex combinatorics involved when considering all possible feature combinations. This can be mitigated by using integer linear programming optimization that is outlined by the Complex Conceptual Spaces Single Observation mathematical model framework. A third challenge is the complicated physics that is involved in a spacecraft collision that must be addressed to obtain a better understanding of threat assessment. Overcoming these various challenges allows for a quantitative ranking for the potential of a kinetic kill collision across multiple spacecraft pairs. In addition to overcoming these challenges this paper will break down threat assessment into four domains and identify a ranking of threat both for each individual domain and for the four domains combined. Simulation results are shown to verify the developed concepts. (shrink)

The philosophy of Plato, universally acknowledged as the most important thinker of the Ancient World, is a major focus of contemporary attention - not only among philosophers, but also classicists and literary and political theorists.

It represents radically different scholarly approaches, and illuminates the key issues in the most hotly debated (...) topics, including Plato's theory of the Forms and Platonic Erotics. It is especially concerned with the interpretations and major debates of philosophers of the Anglo-American schools over the last three decades. (shrink)
