According to spacetime state realism, the fundamental ontology of a quantum mechanical world consists of a state-valued field evolving in four-dimensional spacetime. One chief advantage it claims over rival wave-function realist views is its natural compatibility with relativistic quantum field theory. I argue that the original density operator formulation of SSR cannot be extended to QFTs where the local observables form type III von Neumann algebras. Instead, I propose a new formulation of SSR in terms of a presheaf of local (...) state spaces dual to the net of local observables studied by algebraic QFT. 1Introduction2Spacetime State Realism in Quantum Field Theory 2.1Equivalence thesis3Entanglement and the Type III Property 3.1No-Go Lemma 13.2No-Go Lemma 24State Space Axioms for Quantum Field Theory 4.1Revised equivalence thesis5Discussion.

A major obstacle facing interpreters of quantum field theory is a proliferation of different theoretical frameworks. This article surveys three of the main available options—Lagrangian, Wightman, and algebraic QFT—and examines how they are related. Although each framework emphasizes different aspects of QFT, leading to distinct strengths and weaknesses, there is less tension between them than commonly assumed. Given the limitations of our current knowledge and the need for creative new ideas, I urge philosophers to explore puzzles, tools, and techniques from (...) all three approaches. (shrink)

Jill North argues that Hamiltonian mechanics provides the most spare -- and hence most accurate -- account of the structure of a classical world. We point out some difficulties for her argument, and raise some general points about attempts to minimize structural commitments.

Candidates for fundamental physical laws rarely, if ever, employ higher than second time derivatives. Easwaran sketches an enticing story that purports to explain away this puzzling fact and thereby provides indirect evidence for a particular set of metaphysical theses used in the explanation. I object to both the scope and coherence of Easwaran's account, before going on to defend an alternative, more metaphysically deflationary explanation: in interacting Lagrangian field theories, it is either impossible or very hard to incorporate higher than (...) second time derivatives without rendering the vacuum state unstable. The so-called Ostrogradski instability represents a powerful constraint on the construction of new field theories and supplies a novel, largely overlooked example of non-causal explanation in physics.

The thermal time hypothesis is a proposed solution to the problem of time: a coarse-grained state determines a thermal dynamics according to which it is in equilibrium, and this defines the f...

The CPT theorem states that any causal, Lorentz-invariant, thermodynamically well-behaved quantum field theory must also be invariant under a reflection symmetry that reverses the direction of time, flips spatial parity, and conjugates charge. Although its physical basis remains obscure, CPT symmetry appears to be necessary in order to unify quantum mechanics with relativity. This paper attempts to decipher the physical reasoning behind proofs of the CPT theorem in algebraic quantum field theory. Ultimately, CPT symmetry is linked to a systematic reversal (...) of the C*-algebraic Lie product that encodes the generating relationship between observables and symmetries. In any physically reasonable relativistic quantum field theory it is always possible to systematically reverse this generating relationship while preserving the dynamics, spectra, and localization properties of physical systems. Rather than the product of three separate reflections, CPT symmetry is revealed to be a single global reflection of the theory’s state space. (shrink)

Nature seems to be such that we can describe it accurately with quantum theories of bosons and fermions alone, without resort to parastatistics. This has been seen as a deep mystery: paraparticles make perfect physical sense, so why don’t we see them in nature? We consider one potential answer: every paraparticle theory is physically equivalent to some theory of bosons or fermions, making the absence of paraparticles in our theories a matter of convention rather than a mysterious empirical discovery. We (...) argue that this equivalence thesis holds in all physically admissible quantum field theories falling under the domain of the rigorous Doplicher–Haag–Roberts approach to superselection rules. Inadmissible parastatistical theories are ruled out by a locality-inspired principle we call charge recombination. 1 Introduction2 Paraparticles in Quantum Theory3 Theoretical Equivalence3.1 Field systems in algebraic quantum field theory3.2 Equivalence of field systems4 A Brief History of the Equivalence Thesis4.1 The Green decomposition4.2 Klein transformations4.3 The argument of Drühl, Haag, and Roberts4.4 The Doplicher–Roberts reconstruction theorem5 Sharpening the Thesis6 Discussion6.1 Interpretations of Quantum Mechanics6.2 Structuralism and haecceities6.3 Paraquark theories.

My dissertation asks how we affect conversational context and how it affects us when we participate in any conversation—including philosophical conversations. Chapter 1 argues that speakers make pragmatic presuppositions when they use proper names. I appeal to these presuppositions in giving a treatment of Frege’s puzzle that is consistent with the claim that coreferential proper names have the same semantic value. I outline an explanation of the way presupposition carrying expressions in general behave in belief ascriptions, and suggest that substitutivity (...) failure is a special case of this behavior. Chapter 2 develops a compositional probabilistic semantics for the language of subjective uncertainty, including epistemic adjectives scoped under quantifiers. I argue that we should distinguish sharply between the effects that epistemically hedged statements have on conversational context, and the effects that they have on belief states. I also suggest that epistemically hedged statements are a kind of doxastic advice, and explain how this hypothesis illuminates some otherwise puzzling phenomena. Chapter 3 argues that ordinary causal talk is deeply sensitive to conversational context. The principle that I formulate to characterize that context sensitivity explains at least some of the oddness of ‘systematic causal overdetermination,’ and explains why some putative overgenerated causes are never felicitously counted, in conversation, as causes. But the principle also makes metaphysical theorizing about causation rather indirectly constrained by ordinary language judgments. (shrink)

Beyond Aesthetics brings together philosophical essays addressing art and related issues by one of the foremost philosophers of art at work today. Countering conventional aesthetic theories - those maintaining that authorial intention, art history, morality and emotional responses are irrelevant to the experience of art - Noël Carroll argues for a more pluralistic and commonsensical view in which all of these factors can play a legitimate role in our encounter with art works. Throughout, the book combines philosophical theorizing with illustrative (...) examples including works of high culture and the avant-garde, as well as works of popular culture, jokes, horror novels, and suspense films.

Alexius Meinong advocated a bold new theory of nonexistent objects, where we could gain knowledge and assert true claims of things that did not exist. While the theory has merit in interpreting sentences and solving puzzles, it unfortunately paves the way for contradictions. As Bertrand Russell argued, impossible objects, such as the round square, would have conflicting properties. Meinong and his proponents had a solution to that charge, posing genuine and non-genuine versions of the Law of Non-Contradiction. No doubt, they (...) had a clever response, but it may not adequately address Russell’s concern. Moreover, as I argue, genuine contradictions are inherent to the set of all nonexistent objects. And such contradictions lead to even further absurdities, for example, that nonexistent objects have and lack every property. Unfortunately, such implications of the theory make it too treacherous to adopt. (shrink)

In this article, “Narrative Closure,” a theory of the nature of narrative closure is developed. Narrative closure is identified as the phenomenological feeling of finality that is generated when all the questions saliently posed by the narrative are answered. The article also includes a discussion of the intelligibility of attributing questions to narratives as well as a discussion of the mechanisms that achieve this. The article concludes by addressing certain recent criticisms of the view of narrative expounded by this article.

Alexius Meinong claimed to uncover a brave new world of nonexistent objects. He contended that unreal objects, such as the golden mountain and the round square, genuinely had properties and therefore, deserved a place in an all-inclusive science. Meinong’s notion of nonexistents was initially not well-received, largely due to the influence and criticisms of Bertrand Russell. However, it has gained considerable popularity in more recent years as academics have uncovered shortfalls in Russell’s philosophy and strived to explain apparent “facts” about (...) the beingless. Some philosophers have continued Meinong’s project, further explaining nonexistent objects or formulating logic systems that incorporate them. The more recent developments beg for a re-examination of Meinongianism. This book does just that, putting the theory on trial. Part One considers if Russell truly defeated Meinongianism. It addresses Meinongian rejoinders in response to Russell’s main criticisms and further defends Russell’s alternative solution, his Theory of Descriptions. Part Two explores the rationale for nonexistents and their use in interpreting three types of statements: characterization, negative existential, and intentional. The book argues that, despite appearances, Meinongianism cannot plausibly account for its own paradigm claims, whereas Russell’s framework, with some further elucidation, can explain these statements quite well. Part Three primarily addresses claims about fiction, exploring the short-comings of Meinongian and Russellian frameworks in interpreting them. The book introduces a contextualization solution and symbolic method for capturing the logical form of such claims – one with the complexity to handle cross-contextual statements, including negative existential and intentional ones. It finally considers where that leaves nonexistent objects, ultimately rejecting such so-called entities. (shrink)

As it is presently employed, grounding permits grounding many things from one ground. In this paper, I show why this is a mistake by pushing for a uniqueness principle on grounding. After arguing in favor of this principle, I say something about it and kinds of grounding, discuss a similar principle, and consider its import on a formal feature of grounding, ontology, and ontological simplicity.

Y a-t-il une psychanalyse chrétienne? Cette question a-t-elle un sens? Un croyant souffrant doit-il ou non s'assurer que son psychanalyste est lui-même croyant pour protéger sa foi? Autrement dit, comment l'analyse intègre-t-elle ou modifie-t-elle une donnée religieuse? Faire une analyse, c'est accepter de traverser le tragique de sa propre vie. En raison du dévoilement de la vérité que ce processus met en œuvre, le patient voit se dégager devant lui la perspective d'un désir dont la nouvelle mesure est infinie. Ce (...) désir avait été comblé par des objets qui, jusque-là, semblaient le satisfaire. Puis, le symptôme surgit, déstabilise, perturbe les petits arrangements que le patient s'était autorisés. Première ou dernière scène de son tragique? Dans le huis clos théâtral qu'est la séance analytique, le patient-acteur reprend et parle toute son histoire. Comme à son insu, il se voit contraint de redéfinir ce qui donne sens à sa vie : sens religieux? sens éthique? Bref, tout ce qui échappe à l'analyse et que, paradoxe imprévisible, elle évoque et convoque... Pourtant, un point restera toujours aveugle pour lui, à l'instar d'Œdipe qui, les yeux crevés, poursuit son chemin. C'est peut-être en ce même point - tragique-aveugle - que l'homme reconnaît sous une lumière nouvelle que son histoire personnelle rejoint la détresse commune et ordinaire de toute l'humanité.

Reanimated for the contemporary literature in the writings of Quine, [16]) and Kuhn [7], the conventionalism of Duhem [2] and Poincaré [12] has emerged in the last few years as one of the genuinely interesting topics in the philosophy of science. The theory in question—let us follow Grünbaum [3] in calling it the D-thesis, after its founder, Pierre Duhem—claims three things: a single scientific hypothesis H is never disconfirmable in isolation from its fellow; every single hypothesis H of science presupposes, (...) explicitly or implicitly, the support of a conjunction A = A, • A2 • … • Am of auxiliary assumptions or hypotheses; the failure of an observational consequence of H in face of contradictory evidence disconfirms only the conjunction of H and A, not H alone—i.e. establishes only ∼. The logical picture is as follows. (shrink)

These essays are the fruit of many years' research by one of the world's leading Hobbes scholars. Noel Malcolm offers not only succinct introductions to Hobbes 's life and thought, but also path-breaking studies of many different aspects of his political philosophy, his scientific and religious theories, his relations with his contemporaries, the sources of his ideas, the printing history of his works, and his influence on European thought.

The articles in this volume focus upon Boethius's extant works: his De arithmetica and a fragmentary De musica, his translations and commentaries on logic, his five theological texts, and, of course, his Consolation of Philosophy.

The principles that AN INSTANCE OF A CLASS IS THE CLASS and A CLASS IS AN INSTANCE OF ITSELF allow for the so called LAWS OF THOUGHTIDENTITY - WHAT IS, IS.CONTRADICTION - NOTHING BOTH IS and IS NOT.EXCLUDED MIDDLE - EVERYTHING IS or IS NOT.and allow us to adopt a bivalent system. Everything essential for primary logic is provided.Though this is not the place to discuss it, it should be noted that the development of general logic with its current theories (...) of class, identity and natural numbers could take a very different course from the one it currently pursues.Human thought would have had to evolve to a high level of development before any systematic attempt to analyse it could have been made. It seems it was in the floruit of the Greek civilisation that this attempt was first made. The issues in this paper were of prime concern to those ancient thinkers and their achievements were considerable. Since those times further developments have occurred, many of which they would not have dreamed, but to this day there are still great issues that have not been resolved. The state of the art leaves much to be desired and it is my hope that this paper will contribute to its progress.If the ideas in this paper are true, then it seems we have come across the very origins of human rationality.

When moral or religious teachings have public and political effects, analysis usually focuses on the message, but attention to the manner in which the teachings are communicated is equally important in understanding their power to influence the course of events. Oscar Romero's particular style of moral discourse was remarkably effective for three reasons: First, his moral reasoning resonated with Salvadoran identity. It was intelligible within those reigning assumptions about national history and territory that could actually move a public to action. (...) Second, his moral judgments were timely. Romero sought to discern what was possible for the Salvadoran public at a given moment. Third, Romero had integrity as a public figure. He lived in such a way that his life, and especially his death, became an exemplary embodiment of the larger religious narrative that both grounded his ethics and gave meaning to the nation.

Exponents and critics of semantic presupposition have almost invariably based their discussion on the ('Standard') definition of presupposition implied by Frege and Strawson. In this study Noel Burton-Roberts argues convincingly against this definition, that leads it to a three-valued semantics. He presents a very simple semantic definition which is weaker, more general and leads to a semantics more easily interpreted as two-valued with gaps. The author shows that a wide range of intuitive facts that eluded the Standard definition follow (...) directly from this ('Revised') definition itself: facts about the presuppositions of compound sentences and modal sentences, about presuppositional conflict and about differences in the logical status of simple sentences suffering from presupposition failure. The book includes a detailed argument that an ambiguity of natural language negation, generally assumed to be necessary to the defence of semantic presupposition, is neither possible nor necessary in a presuppositional semantics. Noel Burton-Roberts has made an authoritative contribution to a debate which has involved philosophers and linguists for many years. His command of the issues, his clarity of exposition and his theoretical insight may well serve to change the boundaries of that debate. (shrink)

Prescriptive rules guide human behavior across various domains of community life, including law, morality, and etiquette. What, specifically, are rules in the eyes of their subjects, i.e., those who are expected to abide by them? Over the last sixty years, theorists in the philosophy of law have offered a useful framework with which to consider this question. Some, following H. L. A. Hart, argue that a rule’s text at least sometimes suffices to determine whether the rule itself covers a case. (...) Others, in the spirit of Lon Fuller, believe that there is no way to understand a rule without invoking its purpose — the benevolent ends which it is meant to advance. In this paper we ask whether people associate rules with their textual formulation or their underlying purpose. We find that both text and purpose guide people’s reasoning about the scope of a rule. Overall, a rule’s text more strongly contributed to rule infraction decisions than did its purpose. The balance of these considerations, however, varied across experimental conditions: In conditions favoring a spontaneous judgment, rule interpretation was affected by moral purposes, whereas analytic conditions resulted in a greater adherence to textual interpretations. In sum, our findings suggest that the philosophical debate between textualism and purposivism partly reflects two broader approaches to normative reasoning that vary within and across individuals. Keywords: , the concept of law, rules, legal psychology, Hart, Fuller. (shrink)

The aim of this book is to explain human rationality. The fundamental principles of human thought are stated in terms of Balzer's Principles, and their operations in everyday life are illustrated. The natural numbers are defined and explained in a fresh fashion. Paradoxes, including those of class theory and material implication, which have signaled that all is not well in our logical systems, are laid to rest here. The explanation of human rationality has more than logical interest, for it touches (...) upon the human values embedded in our rationality. The book carries the message that all human beings are fundamentally equal. (shrink)

Continuing work begun by previous scholars, New Directions in Boethian Studies brings together recent studies from the diverse perspective of recent scholarship published during the first decade of Carmina Philosophiae: Journal of the International Boethius Society, a journal which seeks to make sound editions of texts and commentaries, both Latin and vernacular, more readily available to scholars. The book is divided into five sections according to the following areas of study: 1) aspects of Boethius's Latin De Consolatione Philosophiae, 2) vernacular (...) translations of the Consolatio, 3) multidisciplinary perspectives on Boethius in art and literary history, 4) multidisciplinary perspectives on Boethius in art and literary history, and 5) ongoing efforts to find and edit unpublished translations and major studies of Boethius's works. The study of Boethius, his works, and his influence continues to expand as scholars turn their attention to interdisciplinary and heretofore neglected areas of research. The essays and the critical edition presented in this collection represent the ongoing discussions of established and emerging scholars who are drawn to Boethius, undeniably one of the most central and seminal thinkers in the Western tradition.

This book provides a much-needed, straightforward introduction to moral philosophy.

Until the second half of the 19th century the natural numbers were regarded as given and not further analysable. The concept of a class as defined by mathematicians of the time, Seeming more fundamental, Was then used to define the natural numbers. Their definitions of a class are unsuitable because of paradoxes and other difficulties. In this paper a new definition of a class is stated, And from this the natural numbers are defined.

In this chapter, we treat Larry David’s television series, Curb Your Enthusiasm as, in large measure, a philosophical exercise. We argue that it presents a critique of our norms, practices, and conventions of social behavior, notably those that pertain primarily to civility rather than to morality. This critique identifies certain essential features of such behavior including: the typical unspoken-ness of its governing norms, and their non-necessity, despite appearances to the contrary, due to our intense emotional investment in them. In Curb (...) Your Enthusiasm, the ostensible justification that “This is just how we do things” comes in for merciless, satirical interrogation, most often by Larry David but sometimes by others, at Larry David’s expense. This chapter relies heavily on Mary Douglas’s discussion of jokes, but parts company with it in crucial respects. The chapter will also situate Larry David’s brand of humor in the context of the philosophy of comic amusement in terms of the notion of incongruity. Special emphasis will be played on the importance Larry David assigns to emotions in the maintenance of the relevant social norms. (shrink)
