_341_ _Objectives: _In patients with multivessel disease both the detection of the culprit lesion and the exact allocation are important preconditions for sufficient treatment and improved outcome. In a vessel based approach the combination of quantitative coronary angiography and fractional flow reserve measured by a pressure wire should be advantageous compared to myocardial SPECT, as morphological and functional information is delivered simultaneously. Therefore our aim was to evaluate MS in the detection and allocation of hemodynamically significant stenoses obtained by the (...) combined gold standard QCA plus FFR in patients with multivessel disease. _Methods: _FFR and QCA of 95 vessels in 80 patients have been evaluated. Hemodynamically significant target lesions were defined as intermediate stenoses between 50 and 75% with an FFR. (shrink)

This paper responds to Philipona & O’Regan (2006), which attempts to account for certain color phenomena by appeal to singularities in the space of “accessible information” in the light striking the retina. Three points are discussed. First, it is unclear what the empirical significance/import is of the mathematical analysis of the data regarding the accessible information in the light. Second, the singularity index employed in the study is both mathematically and empirically faulty. Third, the connection drawn between their findings and (...) some data from the World Color Survey is lacking in quantitative analysis in places where it is needed. The difficulties raised prevent Philipona & O’Regan’s conclusions from being accepted. (shrink)

This philosophical treatise on the foundations of semantics is a systematic effort to clarify, deepen and defend the classical doctrine that words are conventional signs of mental states, principally thoughts and ideas, and that meaning consists in their expression. This expression theory of meaning is developed by carrying out the Gricean programme, explaining what it is for words to have meaning in terms of speaker meaning, and what it is for a speaker to mean something in terms of intention. But (...) Grice's own formulations are rejected and alternatives developed. The foundations of the expression theory are explored at length, and the author develops the theory of thought as a fundamental cognitive phenomenon distinct from belief and desire, argues for the thesis that thoughts have parts, and identifies ideas or concepts with parts of thoughts. This book will appeal to students and professionals interested in the philosophy of language. (shrink)

In this paper I defend the theory that knowledge is credit-worthy true belief against a family of objections, one of which was leveled against it in a recent paper by Jennifer Lackey. In that paper, Lackey argues that testimonial knowledge is problematic for the credit-worthiness theory because when person A comes to know that p by way of the testimony of person B, it would appear that any credit due to A for coming to believe truly that p belongs to (...) the testifier, B, rather than the hearer, A. If so, then knowledge would appear not to be a matter of credit for true belief. I think that the problem this raises actually has little to do with the fact that the knowledge comes by way of testimony, and that similar objections can be formulated in terms of perceptual and memorial knowledge. I will attempt to neutralize these objections by drawing a distinction between credit as praiseworthiness and credit as attributability. (shrink)

In a recent book, ^[1] Michael Tye has offered a representational theory of phenomenal consciousness. As Tye himself admits, part of his account involves arguing for a position which has traditionally received little support; he contends that _all_ experiences and feelings have representational.

In a recent paper, David Albert has suggested that no quantum theory can yield a description of the world unfolding in Minkowski spacetime. This conclusion is premature; a natural extension of Stein's notion of becoming in Minkowski spacetime to accommodate the demands of quantum nonseparability yields such an account, an account that is in accord with a proposal which was made by Aharonov and Albert but which is dismissed by Albert as a ‘mere trick’. The nature of such an account (...) is clarified by an extension to a relativistic quantum context of David Lewis' picture of objective chances evolving in time. 1 Introduction 2 Classical relativistic becoming 3 Relativistic quantum becoming, without collapse 4 Relativistic quantum becoming, with collapse 5 Objective chance, conditional probability, and definite properties 6 The nature of the wave function 7 Conclusion.

In this paper, it is argued that the prima facie conflict between special relativity and the quantum-mechanical collapse postulate is only apparent, and that the seemingly incompatible accounts of entangled systems undergoing collapse yielded by different reference frames can be regarded as no more than differing accounts of the same processes and events. Attention to the transformation properties of quantum-mechanical states undergoing unitary, non-collapse evolution points the way to a treatment of collapse evolution consistent with the demands of relativity. r (...) 2002 Elsevier Science Ltd.

A proof is given, at a greater level of generality than previous 'no-go' theorems, of the impossibility of formulating a modal interpretation that exhibits 'serious' Lorentz invariance at the fundamental level. Particular attention is given to modal interpretations of the type proposed by Bub.

This new interpretation of Fichte's Jena system focuses on the problem of the objectivity of consciousness.

Informed consent is thought to exist as a well-defined entity. Altered concepts of patient autonomy, differential cultural understanding of the entity, and the failure of clients to distinguish between research and clinical ethics, and various hierarchical cultural views of informed consent all suggest that alterations may be needed in the traditional concept. By using the methodology outlined by Gasking in which he defines the idea of “cluster concepts,” one may be able to enlarge the definition and augment the understanding of (...) the informed consent and include the time and culture-specific variants which exist.

This paper attempts to provide a descriptive theoretical overview of the medical futility debate. I will first argue that quantitative data cannot alone resolve the medical futility debate. I will then examine two aspects of medical futility, which I call the prospective and immediate, respectively. The first involves making prospective factual and value judgments about the efficacy of proposed medical interventions, while the latter involves making value judgments about ongoing medical conditions where the clinical data are clear. At stake is (...) the nature and scope of individual rights. Thus, I maintain there is an undeveloped aspect to the medical futility debate and, briefly, analyze two political perspectives which give rise to different understandings of medical futility. The view that I will defend is that only a system with defined collective goals can accommodate a normative concept of medical futility. These larger questions are the value options which, if unaddressed, may be settled by default of economic grounds. (shrink)

There is significant interest in type-free systems that allow flexible self-application. Such systems are of interest in property theory, natural language semantics, the theory of truth, theoretical computer science, the theory of classes, and category theory. While there are a variety of proposed type-free systems, there is a particularly natural type-free system that we believe is prototypical: the logic of recursive algorithms. Algorithmic logic is the study of basic statements concerning algorithms and the algorithmic rules of inference between such statements. (...) As shown in [1], the threat of paradoxes, such as the Curry paradox, requires care in implementing rules of inference in this context. As in any type-free logic, some traditional rules will fail. The first part of the paper develops a rich collection of inference rules that do not lead to paradox. The second part identifies traditional rules of logic that are paradoxical in algorithmic logic, and so should be viewed with suspicion in type-free logic generally. (shrink)

The Akaike Information Criterion can be a valuable tool of scientific inference. This statistic, or any other statistical method for that matter, cannot, however, be the whole of scientific methodology. In this paper some of the limitations of Akaikean statistical methods are discussed. It is argued that the full import of empirical evidence is realized only by adopting a richer ideal of empirical success than predictive accuracy, and that the ability of a theory to turn phenomena into accurate, agreeing measurements (...) of causally relevant parameters contributes to the evidential support of the theory. This is illustrated by Newton's argument from orbital phenomena to the inverse-square law of gravitation. (shrink)

In Practical Reality, Jonathan Dancy argues that our reasons for action are not psychological states, but things we take to be facts about the world, and shows that the reasons themselves are not causes. Dancy concludes that intentional actions are not explained by beliefs and desires, and that explanations of action in terms of reasons are not causal explanations. I show that these further conclusions are unwarranted by sketching an alternative theory of reasons according to which what it is for (...) an action to be done for a reason is for certain beliefs and desires to cause the action. Our reasons for action are the contents of those beliefs and desires. This theory is not only compatible with the facts about reasons Dancy has established, but explains many things that Dancy’s theory does not account for. I make no claim here about the precise adequacy of the simplified theoretical definitions I present. My goal is to show that a systematic theory along these lines is a promising approach to understanding an important aspect of human nature. (shrink)

We develop a functional abstraction principle for the type-free algorithmic logic introduced in our earlier work. Our approach is based on the standard combinators but is supplemented by the novel use of evaluation trees. Then we show that the abstraction principle leads to a Curry fixed point, a statement C that asserts C ⇒ A where A is any given statement. When A is false, such a C yields a paradoxical situation. As discussed in our earlier work, this situation leaves (...) one no choice but to restrict the use of a certain class of implicational rules including modus ponens. (shrink)

Grice’s Razor is a methodological principle that many philosophers and linguists have used to help justify pragmatic explanations of linguistic phenomena over semantic explanations. A number of authors in the debate over contextualism argue that an invariant semantics together with Grice’s (1975) conversational principles can account for the contextual variability of knowledge claims. I show here that the defense of Grice’s Razor found in these “Gricean invariantists,” and its use against epistemic contextualism, display all the problems pointed out earlier in (...) Davis (1998). The everyday variation in acceptable knowledge claims is better explained in terms of implicature than indexicality, but general conversational principles shed little light on whether ‘know’ is used hyperbolically, meiotically, or loosely in a context, although this issue is crucial in deciding what if anything ‘S knows p’ implicates. I present reasons favoring an account of the representative bank case in terms of loose use, making clear how they differ from Grice’s Razor. (shrink)

This review essay emphasizes the distinction between academic art history, based ultimately on the model of scientific research, and the sort that Roberto Calasso practices in his 2009 study Tiepolo in Pink. It is difficult to locate the book's genre, and the reviewer rejects identifying it as a biography (of the sort practiced by Irving Stone, Somerset Maugham, and Dimitri Merejkovski), since Calasso, like most other writers on Tiepolo, stresses how little we know about his personality, which was elusive, and (...) about his private life, which was undramatic. What chiefly interests both Calasso and the reviewer is whether Tiepolo, whose ceiling frescoes are without gravity—their “antigravity” draws the painted figures upward—is an artist without gravitas. The reviewer supports Calasso's argument that the thirty-two etchings comprising the Capricci and Scherzi make it absurd to consider Tiepolo artistically, intellectually, or morally frivolous. “Scientific” art historians have applied the category of “decoration” to these somber etchings, with their incomprehensible allegories, but Calasso, himself an artist (a novelist), approaches these pictures without scientific prejudice. The reviewer traces the dour attitude of mainstream art historians toward Tiepolo to his rivalry for commissions in the 1760s with Anton Raphael Mengs, a representative of the rising Enlightenment cult of virtue and the austere aesthetics of a rising neoclassicism. From that time on, art historians have treated Tiepolo's work as unhealthy, lightweight, and bizarre, but this review supports Calasso's claim that his work is actually sober and moving. The review concludes that there are artists whom the narrow sensibility of standard art historians will never be able to accommodate, Tiepolo being only one among several. (shrink)

Husserl's explication of "self" and "others" occurs within his founding science of pure possibilities or "bracketed" consciousness and experience. His analysis of self and others seeks, in part, to demonstrate that "personal" or "self-experience" is not the only possibility of immanent consciousness but that "other persons" are also given as possibilities. The possibility of others, though in a form of givenness different from that of self, provides a basis for inter-subjectivity. Thus, Husserl's phenomenological analysis can, if it does avoid solipsism (...) and subjective idealism in general, establish inter-subjectivity as coextensive with subjectivity within the deepest possibilities of experience. Husserl's discussion of how the other as an external person or alien ego occurs as a given after all beliefs in an independently existing world are suspended (bracketed) shares some interesting parallels with psychological concepts and also suggests foundational possibilities for research on how the other is constituted as a separate "person" within our consciousness.

Earman and Ruetsche ([2005]) have cast their gaze upon existing no-go theorems for relativistic modal interpretations, and have found them inconclusive. They suggest that it would be more fruitful to investigate modal interpretations proposed for "really relativistic theories," that is, algebraic relativistic quantum field theories. They investigate the proposal of Clifton ([2000]), and extend Clifton's result that, for a host of states, his proposal yields no definite observables other than multiples of the identity. This leads Earman and Ruetsche to a (...) suspicion that troubles for modal interpretations of such relativistic theories "are due less to the Poincaré invariance of relativistic QFT vs. the Galilean invariance of ordinary nonrelativistic QM than to the infinite number of degrees of freedom of former vs. the finite number of degrees of freedom of the latter" (577-78). I am skeptical of this suggestion. Though there are troubles for modal interpretations of a relativistic quantum field theory that are due to its being a field theory—that is, due to infinitude of the degrees of freedom—they are not the only troubles faced by modal interpretations of quantum theories set in relativistic spacetime; there are also troubles traceable to relativistic causal structure.

Hegel's very first acknowledged publication was, among other things, an attack on Fichte. In 1801, Hegel was still laboring in almost complete obscurity, while Fichte was an international sensation, though already somewhat past the peak of his meteoric career. In the 1801 Differenzschrift, Hegel cut his teeth by criticizing Fichte's already widelycriticised Wissenschaftslehre, and by demonstrating that Schelling's philosophical system was not simply to be equated with it. Fichte himself never bothered to respond to Hegel's criticisms; indeed he never publicly (...) acknowledged their existence. This was not because he was unconcerned with criticisms of his views; quite the contrary. But at the time he had bigger fish to fry. He responded to Jacobi's criticisms, and to Schelling's; he replied in great detail to critical questions raised by Reinhold, and with vituperative intensity to objections raised by skeptics and purportedly loyal Kantians. But Hegel's Differenzschrift was left without a Fichtean rebuttal. This is a pity, both because of the missed opportunity to illuminate by controversy central issues at stake in the post-Kantian period, but also because it made it easier for Hegel simply to reiterate his youthful criticism as if it were the last word. And reiterate it he did: in one form or another Hegel's early criticisms of Fichte reappear at every subsequent stage of his career: in the Phenomenology, in the Science of Logic, in the Encyclopaedia, as the final chapter in Hegel's History of Philosophy, and in countless other minor works and documents from the Nachlass and correspondence.

This paper addresses the question of how we should regard the probability distributions introduced into statistical mechanics. It will be argued that it is problematic to take them either as purely subjective credences, or as objective chances. I will propose a third alternative: they are "almost objective" probabilities, or "epistemic chances". The definition of such probabilities involves an interweaving of epistemic and physical considerations, and so cannot be classified as either purely subjective or purely objective. This conception, it will be (...) argued, resolves some of the puzzles associated with statistical mechanical probabilities; it explains how probabilistic posits introduced on the basis of incomplete knowledge can yield testable predictions, and it also bypasses the problem of disastrous retrodictions, that is, the fact the standard equilibrium measures yield high probability of the system being in equilibrium in the recent past, even when we know otherwise. As the problem does not arise on the conception of probabilities considered here, there is no need to invoke a Past Hypothesis as a special posit to avoid it. (shrink)

Since there have been many recent occurrences of alleged wrongdoing by business persons and other professionals, it seems additional ethics research is needed to obtain knowledge that will impact real-world behavior. An empirical study assessed business students’ impressions of hypothetical wrongdoers and whistleblowers. To some extent, impressions of an unethical executive and a whistleblower were influenced by the same variables and in opposite directions. Female respondents judged the unethical executive less favorably and the whistleblower more favorably than did males. The (...) executive was rated less favorably and the whistleblower more favorably when the executive sought a small gain than when the goal was a large gain or prevention of a loss of either magnitude. Some manipulations, however, impacted impressions of one actor, but not the other. Perhaps ethics training can make students aware that issue␣framing and moral intensity components may bias decisions. (shrink)

Berg seeks to defend the theory that the meaning of a proper name in a belief report is its reference against Frege’s puzzle by hypothesizing that when substituting coreferential names in belief reports results in reports that seem to have different truth values, the appearance is due to the fact that the reports have different metalinguistic implicatures. I review evidence that implicatures cannot be calculated in the way Grice or Berg imagine, and give reasons to believe that belief reports do (...) not have the implicatures Berg attributes to them. I also argue that even if belief reports did have such implicatures, they would not explain why the belief reports in Frege’s puzzle seem to have different truth values. I point out that Berg has no reason to believe that Lois Lane believes Clark Kent is a reporter and Lois Lane believes Superman is a reporter are both true rather than both false, and that Leibniz’s Law cannot be used to defend substitutivity in belief reports because belief reports are not relational in the requisite way. Finally, I observe that some of the linguistic data Berg uses to argue for substitutivity in belief reports concerns the transparent interpretation of belief reports, whereas Frege’s puzzle concerns the opaque interpretation.

To avoid problems with classical theories that take our mental states to represent in virtue of what propositions they represent, and more recent theories that reverse the representational priority, Grzankowski and Buchanan (Philos Stud 176:3159–3178, 2019) propose a “cheap” theory of propositions that does not assume that they are representational entities. They believe that everything there is to know about propositions is provided by the principle that token mental states have the same propositional content if they represent the same things (...) in the same way. I show that the postulated correlation of propositions with mental states does not suffice for propositions to have standard properties like truth values or constituent structures, or to secure the truth of their other basic principle “essentiality of content.” Their theory tells us so little about what propositions are that there is no reason to believe that propositions are object of mental states, or that they exist at all.

The death of any great philosopher invariably spawns a plethora of essays in defense, refutation, or explication. Indeed, the sign of the philosopher’s greatness can be measured by the number of essays his work generates. Hannah Arendt once commented on the generation of writers Karl Marx supported. This is as it should be. For greatness needs criticism as much as it requires testimony. And the testimony which follows is that of a defense; one which seeks to clarify a longstanding paradox (...) in Arendt’s work. (shrink)
