Humans have long been fascinated by the idea of visiting the past and of seeing what the future will bring. Time travel has been one of the most popular themes of science fiction. Most people have seen the TV series ‘Dr Who’ or ‘Quantum Leap’ or ‘Star Trek’. You’ve probably seen one of the ‘Back to the Future’ or ‘Terminator’ movies, or ‘Twelve Monkeys’. Time travel narratives provide fascinating plots, which exercise our imaginations in ever so many ways. But is (...) the idea of travelling forward and backward in time pure fantasy—or can it be done? To be sure, not all time travel scenarios are coherent. But we hope to persuade you that the most common objections to the very idea of time travel have no real force. (shrink)
Philosophers, linguists and others interested in problems concerning natural language frequently employ tools from logic and model theory. The question arises as to the proper interpretation of the formal methods employed—of the relationship between, on the one hand, the formal languages and their set-theoretic models and, on the other hand, the objects of ultimate interest: natural language and the meanings and truth conditions of its constituent words, phrases and sentences. Two familiar answers to this question are descriptivism and instrumentalism. More (...) recently, a third answer has been proposed: the logic as modelling view. This paper seeks to clarify and assess this view of logic. The conclusion is that we can successfully adopt the modelling perspective on a given piece of logical machinery only if we have to hand some other machinery to which we take the descriptive attitude. Thus, logic as modelling is not a full-fledged alternative to the descriptive view— for it cannot stand alone: it can at best be an addition to the descriptive perspective. The paper first presents the argument in a general, abstract form, before working through a detailed case study. The case examined is the one with respect to which the logic as modelling view has been developed in the greatest detail in the literature: the case of fuzzy model theory as an account of vagueness in natural language.

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)
A many-valued (aka multiple- or multi-valued) semantics, in the strict sense, is one which employs more than two truth values; in the loose sense it is one which countenances more than two truth statuses. So if, for example, we say that there are only two truth values—True and False—but allow that as well as possessing the value True and possessing the value False, propositions may also have a third truth status—possessing neither truth value—then we have a many-valued semantics in the (...) loose but not the strict sense. A many-valued logic is one which arises from a many-valued semantics and does not also arise from any two-valued semantics [Malinowski, 1993, 30]. By a ‘logic’ here we mean either a set of tautologies, or a consequence relation. We can best explain these ideas by considering the case of classical propositional logic. The language contains the usual basic symbols (propositional constants p, q, r, . . .; connectives ¬, ∧, ∨, →, ↔; and parentheses) and well-formed formulas are defined in the standard way. With the language thus specified—as a set of well-formed formulas—its semantics is then given in three parts. (i) A model of a logical language consists in a free assignment of semantic values to basic items of the non-logical vocabulary. Here the basic items of the non-logical vocabulary are the propositional constants. The appropriate kind of semantic value for a proposition is a truth value, and so a model of the language consists in a free assignment of truth values to basic propositions. Two truth values are countenanced: 1 (representing truth) and 0 (representing falsity). (ii) Rules are presented which determine a truth value for every proposition of the language, given a model. The most common way of presenting these rules is via truth tables (Figure 1). Another way of stating such rules—which will be useful below—is first to introduce functions on the truth values themselves: a unary function ¬ and four binary functions ∧, ∨, → and ↔ (Figure 2)..

The major reason given in the philosophical literature for dissatisfaction with theories of vagueness based on fuzzy logic is that such theories give rise to a problem of higherorder vagueness or artificial precision. In this paper I first outline the problem and survey suggested solutions: fuzzy epistemicism; measuring truth on an ordinal scale; logic as modelling; fuzzy metalanguages; blurry sets; and fuzzy plurivaluationism. I then argue that in order to decide upon a solution, we need to understand the true nature (...) and source of the problem. Two possible sources are discussed: the problem stems from the very nature of vagueness—from the defining features of vague predicates; or the problem stems from the way in which the meanings of predicates are determined—by the usage of speakers together with facts about their environment and so on. I argue that the latter is the true source of the problem, and on this basis that fuzzy plurivaluationism is the correct solution. (shrink)
In our reply to Rowe, we explain why most of what he criticizes is actually the product of his misunderstanding our argument. We begin by showing that nearly all of his Part 1 misconceives our project by defending a position we never attacked. We then question why Rowe thinks the distinction we make between motivational and virtue intellectualism is unimportant before developing a defense of the consistency of our views about different desires. Next we turn to Rowe’s criticisms of our (...) account of the prudential paradox and show these criticisms to rest on a misunderstanding. We close with some remarks about the implausibility and textual problems Rowe faces in denying that Socrates recognized a role for painful punishments. (shrink)
The book thus serves both as an introduction to logic itself and to the philosophy of logic."--Stewart Shapiro, editor of "The Oxford Handbook of Philosophy of Mathematics and Logic".
In this article we examine the idea of a politics of misrecognition of working activity. We begin by introducing a distinction between the kind of recognition and misrecognition that attaches to one’s identity, and the kind of recognition and misrecognition that attaches to one’s activity. We then consider the political significance of the latter kind of recognition and misrecognition in the context of work. Drawing first on empirical research undertaken by sociologists at the Institut für Sozialforschung in Frankfurt, we argue (...) for a differentiated concept of recognition that shows the politics of misrecognition at work to be as much a matter of conflict between modes of recognition as it is a struggle for recognition as opposed to non -recognition. The differentiated concept of recognition which allows for this empirical insight owes much to Axel Honneth’s theory. But as we argue in the section that follows, this theory is ambiguous about the normative content of the expectations of recognition that are bound up with the activity of working. This in turn makes it unclear how we should understand the normative basis of the politics of the misrecognition of what one does at work. In the final sections of the article, we suggest that the psychodynamic model of work elaborated by Christophe Dejours and others at the Conservatoire National des Arts et Métiers in Paris can shed light on this matter; that is to say, it can help to clarify the normative significance and political stakes of the misrecognition of working activity.

In this paper, we review Keith Lehrer’s account of the basing relation, with particular attention to the two cases he offered in support of his theory, Raco (Lehrer, Theory of knowledge, 1990; Theory of knowledge, (2nd ed.), 2000) and the earlier case of the superstitious lawyer (Lehrer, The Journal of Philosophy, 68, 311–313, 1971). We show that Lehrer’s examples succeed in making his case that beliefs need not be based on the evidence, in order to be justified. These cases show (...) that it is the justification (rather than the belief) that must be based in the evidence. We compare Lehrer’s account of basing with some alternative accounts that have been offered, and show why Lehrer’s own account is more plausible. (shrink)
This volume addresses the long-standing neglect of the category of labour in critical social theory and it presents a powerful case for a new paradigm based on the anthropological significance of work and its role in shaping social bonds.
This paper presents a new argument against A-theories of time. A-theorists hold that there is an objective now (present moment) and an objective flow of time, the latter constituted by the movement of the objective now through time. A-theorists therefore want to draw different pictures of reality—showing the objective now in different positions—depending upon the time at which the picture is drawn. In this paper it is argued that the times at which the different pictures are drawn may be taken (...) to be normal times or hypertimes. If they are normal times then the A-theory is inconsistent, or else collapses to the B-theory—and appealing to primitive tense operators will not help A-theorists avoid this conclusion. If the times are hypertimes then the A-theory is consistent, but deeply problematic none the less. (shrink)
This is the first book-length philosophical study of Husserl’s transcendental phenomenology and Freud’s theory of the unconscious. The book investigates the possibility for Husserl’s transcendental phenomenology to clarify Freud’s concept of the unconscious with a focus on the theory of repression as its centre. Repression is the unconscious activity of pushing something away from consciousness, while making sure that it remains active as something foreign within us. How this is possible is the main problem addressed in the work. Unlike previous (...) literature (including Ricœur, Merleau-Ponty and Derrida) this book makes full use of the resources of genetic phenomenology and passivity in the attempt to clarify the Freudian unconscious. The central argument developed is that the structure of the lebendige Gegenwart as the core of Husserl’s theory of passivity consists of preliminary forms of bodily kinaesthesia, feelings and drives in a constantly ongoing process where repression occurs as a necessary part of all constitution. The clarification of Freudian repression thus takes place by showing how it presupposes a broad conception of consciousness such as that presented by Husserl’s genetic phenomenology. By arguing that “repression” is central to any philosophical account of subjectivity, this book takes on the most distinct challenge to philosophy posed by Freud. (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)

The paper contrasts two approaches to the analysis of hope: one that takes its departure from a view broadly shared by Hobbes, Locke and Hume, another that fits better with Aquinas's definition of hope. The former relies heavily on a sharp distinction between the cognitive and conative aspects of hope. It is argued that while this approach provides a valuable source of insights, its focus is too narrow and it rests on a problematic rationalistic psychology. The argument is supported by (...) a discussion of hope understood as a stance and by a consideration of the phenomenological contrast between expectation and anticipation. The paper concludes with some reflections on the relation between hope and illusion and the idea of responsible hope. (shrink)
This article examines Levinas as if he were a participant in what Habermas has called `the philosophical discourse of modernity'. It begins by comparing Levinas' and Habermas' articulations of the philosophical problems of modernity. It then turns to how certain key motifs in Levinas' later work give philosophical expression to the needs of the times as Levinas diagnoses them. In particular it examines how Levinas interweaves a modern, post-ontological conception of `the religious' or `the sacred' into his account of subjectivity. (...) Finally, the article looks at some problems that arise for Levinas once his position in the philosophical discourse on modernity is made explicit. Key Words: Jürgen Habermas • Emmanuel Levinas • modernity • ontology • otherness • religion • social relation. (shrink)

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.

There has been little scholarly attention given to explaining exactly how and why Socrates thinks that wrongdoing damages the soul. But there is more than a simple gap in the literature here, we shall argue. The most widely accepted view of Socratic moral psychology, we claim, actually leaves this well-known feature of Socrates’ philosophy absolutely inexplicable. In the first section of this paper, we rehearse this view of Socratic moral psychology, and explain its inadequacy on the issue of the damaging (...) consequences of wrongdoing. We then go on to provide our own account of the way in which injustice damages the soul, and then draw conclusions about how Socratic moral psychology should be understood. (shrink)
The paper attempts to situate Sennett philosophically by placing him in the tradition of ontological hermeneutics. This way of reading Sennett is justified not only by the core principles that govern Sennett's social anthropology, but is also useful for tracing the trajectory of Sennett's philosophically informed diagnoses of the times. These diagnoses focus on the role of work in shaping subjectivity. After reconstructing the basic conceptual shape of Sennett's diagnoses of the work-related maladies of the "old" and the "new" capitalism, (...) the paper presents some broader reflections on the philosophical presuppositions of social criticism that takes its departure from the centrality of work.

Orthodoxy has it that mereological composition can never be a vague matter, for if it were, then existence would sometimes be a vague matter too, and that's impossible. I accept that vague composition implies vague existence, but deny that either is impossible. In this paper I develop degree-theoretic versions of quantified modal logic and of mereology, and combine them in a framework that allows us to make clear sense of vague composition and vague existence, and the relationships between them.
In the first part of the paper I consider the relative neglect of hope in the tradition of critical theory. I attribute this neglect to a low estimation of the cognitive, aesthetic, and moral value of hope, and to the strong—but, I argue, contingent—association that holds between hope and religion. I then distinguish three strategies for thinking about the justification of social hope; one which appeals to a notion of unfulfilled or frustrated natural human capacities, another which invokes a providential (...) order, and a third which questions the very appropriateness of justification, turning instead to a notion of ungroundable hope. Different senses of ungroundable hope are distinguished and by way of conclusion I briefly consider their relevance for the project of critique today. (shrink)
The article considers how Richard Rorty's writings on religion dovetail with his views on the philosophical significance of hope. It begins with a reconstruction of the central features of Rorty's philosophy of religion, including its critique of theism and its attempt to rehabilitate religion within a pragmatist philosophical framework. It then presents some criticisms of Rorty's proposal. It is argued first that Rorty's "redescription" of the fulfilment of the religious impulse is so radical that it is hard to see what (...) remains of its specifically religious content. This casts doubt on Rorty's claim to have made pragmatism and religion compatible. The article then offers an analysis of Rorty's key notion of "unjustifiable hope". Different senses of unjustifiable hope are distinguished, in the course of which a tension between the "romantic" and "utilitarian" aspects of Rorty's pragmatist philosophy of religion comes into view.

Although they might not express themselves in quite this way, non-philosophers tend to think that mereological composition is a vague matter : sometimes it occurs, sometimes it does not, and sometimes it sort of occurs. For example, when I am building a boat, at first the timbers that I have acquired for the job do not jointly compose an entity; in the end they do—they compose the boat that I have built; and in between they sort of or more or (...) less or to some extent compose an entity, which in turn sort of or more or less or to some extent exists—this entity being the boat I am building. This idea seems innocuous enough. However, the orthodox view amongst philosophers is that composition can never be a vague matter, because vague composition entails vague existence (the common-sense view agrees with this step), and vague existence is impossible if not nonsensical. Let us call the following the ‘orthodox argument’. (shrink)
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)

This paper presents a new theory of vagueness, which is designed to retain the virtues of the fuzzy theory, while avoiding the problem of higher-order vagueness. The theory presented here accommodates the idea that for any statement S1 to the effect that 'Bob is bald' is x true, for x in [0,1], there should be a further statement S2 which tells us how true S1 is, and so on---that is, it accommodates higher-order vagueness---without resorting to the claim that the metalanguage (...) in which the semantics of vagueness is presented is itself vague, and without requiring us to abandon the idea that the logic---as opposed to the semantics---of vague discourse is classical. I model the extension of a vague predicate P as a BLURRY SET, this being a function which assigns a degree of membership or DEGREE FUNCTION to each object o, where a degree function in turn assigns an element of [0,1] to each finite sequence of elements of [0,1]. The idea is that the assignment to the sequence (0.3,0.2), for example, represents the degree to which it is true to say that it is 0.2 true that o is P to degree 0.3. The philosophical merits of my theory are discussed in detail, and the theory is compared with other extensions and generalisations of fuzzy logic in the literature. (shrink)
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. (shrink)
Socrates is one of the most important yet enigmatic philosophers of all time; his fame has endured for centuries despite the fact that he never actually wrote anything. In 399 B.C.E., he was tried on the charge of impiety by the citizens of Athens, convicted by a jury, and sentenced to death (ordered to drink poison derived from hemlock). About these facts there is no disagreement. However, as the sources collected in this book and the scholarly essays that follow them (...) show, several of even the most basic facts about these events were controversial in antiquity, and the questions persist today: How and why was Socrates brought to trial? Why did the jurors, members of the world's first democracy, find him guilty? When he was given an opportunity to escape execution, why did he refuse to do so and instead accept the punishment that he and his friends agreed was unjustly assigned to him? How exactly did Socrates die? Differences of opinion on these and other issues continue to arouse our curiosity and to challenge new generations of students and scholars. The Trial and Execution of Socrates: Sources and Controversies is the first work to collect in one place all of the major ancient sources on Socrates' death--those of both his critics and his defenders--as well as recent scholarly views. Part I includes new translations of Plato's Euthyphro, Apology, Crito, and the death scene from Phaedo, as well as other ancient sources that shed light on Socrates' trial and execution. Part II features some of the most influential recent scholarship on this historically momentous event with work by M. F. Burnyeat, Robert Parker, Mark L. McPherran, Thomas C. Brickhouse and Nicholas D. Smith, Richard Kraut, Christopher Gill, and Enid Bloch (whose essay is published here for the first time). Ideal for undergraduate surveys of ancient Greek philosophy and upper-level courses on Socrates and Socratic philosophy, this unique collection provides an unprecedented look into the many perplexing questions surrounding the trial and execution of this remarkable man.

In this paper, I argue that several of the main issues that became a focus for classical Greek philosophy were initially framed by Homer. In particular, Homer identifies a tension between justice and individual excellence, and problematizes the connection between the heroic conception of excellence and ``eudaimonia'''' (happiness). The later philosophers address the problems raised in Homer by profoundly transforming the way each of these terms was to be conceived.

In Part I of this paper, I argue that the arguments Plato offers for the tripartition of the soul are founded upon an equivocation, and that each of the valid options by which Plato might remove the equivocation will not produce a tripartite soul. In Part II, I argue that Plato is not wholly committed to an analogy of soul and state that would require either a tripartite state or a tripartite soul for the analogy to hold. It follows that (...) the heart of the analogy is not to be found in the comparison of the Kallipolis and its three parts to the soul conceived as tripartite, but rather must be supposed to reside in some other connection between the ways in which justice characterizes states and souls, and I will suggest what this other connection consists in.

In the Protagoras, Socrates argues that each of the virtue-terms refers to one thing (: 333b4). But in the Laches (190c8–d5, 199e6–7), Socrates claims that courage is a proper part of virtue as a whole, and at Euthyphro 11e7–12e2, Socrates says that piety is a proper part of justice. But A cannot be both identical to B and also a proper part of B – piety cannot be both identical to justice and also a proper part of justice. In this (...) paper we argue that coherent sense can be made of Socrates'' apparently conflicting claims. The key to understanding Socrates'' position, we will argue, is the central role of wisdom among the virtues. It is through the relationship of each virtue to wisdom that each may be said to be the same as all of the others, on the one hand, and also that some virtues may be regarded as proper parts of some other virtues, or as proper parts of virtue in general, on the other.

Strong Hermeneutics presents a compelling case for the importance of hermeneutics in understanding ethics today. It provides a critical comparison of the enlightenment view of ethics with the postmodern or "weak" view of ethics. The weak view, which Nicholas H. Smith traces back to Nietzsche and identifies in the recent work of Rorty and Lyotard, is skeptical of any universal principles in ethics. The enlightenment view, starting with Kant and taken up in the work of Habermas, casts identity as subject (...) of universal but formal moral constraints. Smith argues that neither of these views can provide a proper framework for ethics. Drawing on the work of Hans-Georg Gadamer, Paul Ricoeur and Charles Taylor, he presents a fascinating reworking of key issues in ethics and continental philosophy. (shrink)
This paper argues that the most famous objection to backward time travel can carry no weight. In its classic form, the objection is that backward time travel entails the occurrence of impossible things, such as auto-infanticide—and hence is itself impossible. David Lewis has rebutted the classic version of the objection: auto-infanticide is prevented by coincidences, such as time travellers slipping on banana peels as they attempt to murder their younger selves. I focus on Paul Horwich‘s more recent version of the (...) objection, according to which backward time travel entails not impossible things, but improbable ones—such as the string of slips on banana peels that would be required to stop a determined auto-infanticidal maniac from murdering her younger self—and hence is itself highly improbable. I argue that backward time travel does not entail unusual numbers of coincidences; and that, even if it did, that would not render its occurrence unlikely. (shrink)
Socrates, as he is portrayed in Plato's early dialogues, remains one of the most controversial figures in the history of philosophy. This book concerns six of the most vexing and often discussed features of Plato's portrayal: Socrates' methodology, epistemology, psychology, ethics, politics, and religion. Brickhouse and Smith cast new light on Plato's early dialogues by providing novel analyses of many of the doctrines and practices for which Socrates is best known. Included are discussions of Socrates' moral method, his profession of (...) ignorance, his denial of akrasia, as well as his views about the relationship between virtue and happiness, the authority of the State, and the epistemic status of his daimonion. By revealing the many interconnections among Socrates' views on a wide variety of topics, this book demonstrates both the richness and the remarkable coherence of the philosophy of Plato's Socrates.

Epiphenomenalism is a theory concerning the relation between the mental and physical realms, regarded as radically different in nature. The theory holds that only physical states have causal power, and that mental states are completely dependent on them. The mental realm, for epiphenomenalists, is nothing more than a series of conscious states which signify the occurrence of states of the nervous system, but which play no causal role. For example, my feeling sleepy does not cause my yawning — rather, both (...) the feeling and the yawning are effects of an underlying neural state. (shrink)
