It has been well documented, and fairly well known, that concomitant with an increase in chronological age is a corresponding increase in sensory impairment. As most people realize, our hearing suffers as we get older; hence, the increased need for hearing aids. The first portion of the present paper is how the change in age apparently affects auditory judgments of sound source position. A summary of the literature evaluating the changes in the perception of sound source location and the perception (...) of sound source motion as a function of chronological age is presented. The review is limited to empirical studies with behavioral findings involving humans. It is the view of the author that we have an immensely limited understanding of how chronological age affects perception of space when based on sound. In the latter part of the paper, discussion is given to how auditory spatial perception is traditionally conducted in the laboratory. Theoretically, beneficial reasons exist for conducting research in the manner it has been. Nonetheless, from an ecological perspective, the vast majority of previous research can be considered unnatural and greatly lacking in ecological validity. Suggestions for an alternative and more ecologically valid approach to the investigation of auditory spatial perception are proposed. It is believed an ecological approach to auditory spatial perception will enhance our understanding of the extent to which individuals perceive sound source location and how those perceptual judgments change with an increase in chronological age.

Rumination is a key feature of depression and contributes to its onset, maintenance, and recurrence. Researchers have proposed that biases in the attentional processing of emotional information may underlie rumination, and particularly, the brooding component. This investigation evaluated associations between attentional biases for emotional images and rumination, including both brooding and reflection, in currently and never depressed participants. In two separate studies, participants viewed sets of four emotional images (happy, sad, threatening, and neutral) for 8 s in a free-viewing eye-tracking (...) paradigm. In both studies, currently depressed individuals attended to happy face images and happy naturalistic images significantly less than never depressed individuals. In Study 2, currently depressed individuals attended to sad naturalistic images significantly more than never depressed individuals. There were no statistically significant associations between attentional biases and any of the forms of rumination, independent of their shared relationship with depression symptoms. These findings call into question the robustness of the link between attentional biases and rumination. (shrink)

This book aims to provide a solution to the semantic paradoxes. It argues for a unified solution to the paradoxes generated by our concepts of denotation, predicate extension, and truth. The solution makes two main claims. The first is that our semantic expressions 'denotes', 'extension' and 'true' are context-sensitive. The second, inspired by a brief, tantalizing remark of Godel's, is that these expressions are significant everywhere except for certain singularities, in analogy with division by zero. A formal theory of singularities (...) is presented and applied to a wide variety of versions of the definability paradoxes, Russell's paradox, and the Liar paradox. Keith Simmons argues that the singularity theory satisfies the following desiderata: it recognizes that the proper setting of the semantic paradoxes is natural language, not regimented formal languages; it minimizes any revision to our semantic concepts; it respects as far as possible Tarski's intuition that natural languages are universal; it responds adequately to the threat of revenge paradoxes; and it preserves classical logic and semantics. Simmons draws out the consequences of the singularity theory for deflationary views of our semantic concepts, and concludes that if we accept the singularity theory, we must reject deflationism.

'Justice' and 'democracy' have alternated as dominant themes in political philosophy over the last fifty years. Since its revival in the middle of the twentieth century, political philosophy has focused on first one and then the other of these two themes. Rarely, however, has it succeeded in holding them in joint focus. This volume brings together leading authors who consider the relationship between democracy and justice in a set of specially written chapters. The intrinsic justness of democracy is challenged, the (...) relationship between justice, democracy and impartiality queried and the relationship between justice, democracy and the common good examined. Further chapters explore the problem of social exclusion and issues surrounding sub-national groups in the context of democracy and justice. Authors include Keith Dowding, Richard Arneson, Norman Schofield, Albert Weale, Robert E. Goodin, Jon Elster, David Miller, Phillip Pettit, Julian LeGrand and Russell Hardin. (shrink)

Definite descriptions, I shall argue, have two possible functions. 1] They are used to refer to what a speaker wishes to talk about, but they are also used quite differently. Moreover, a definite description occurring in one and the same sentence may, on different occasions of its use, function in either way. The failure to deal with this duality of function obscures the genuine referring use of definite descriptions. The best known theories of definite descriptions, those of Russell and (...) Strawson, I shall suggest, are both guilty of this. Before discussing this distinction in use, I will mention some features of these theories to which it is especially relevant. (shrink)

In this paper I present two new paradoxes, a definability paradox (related to the paradoxes of Berry, Richard and König), and a paradox about extensions (related to Russell’s paradox). However, unlike the familiar definability paradoxes and Russell’s paradox, these new paradoxes involve no self-reference or circularity.

I argue for an account of semantic paradox that requires minimal logical revision. I first consider a phenomenon that is common to the paradoxes of definability, Russell’s paradox and the Liar. The phenomenon—which I call Repetition—is this: given a paradoxical expression, we can go on to produce a semantically unproblematic expression composed of the very same words. I argue that Kripke’s and Field’s theories of truth make heavy weather of Repetition, and suggest a simpler contextual account. I go on (...) to outline a ‘singularity’ theory of semantical predicates in the spirit of remarks of Gödel. According to this theory, ‘denotes’, ‘extension’ and ‘true’ are context-sensitive expression that apply almost everywhere on a given occasion of use, except for certain singular points. I then turn to revenge paradoxes, and argue that even the dialetheist is subject to revenge. I then examine how the singularity theory responds to revenge. (shrink)

Informed by the philosophy of the virtual, Keith Ansell Pearson offers up one of the most lucid and original works on the central philosophical questions. He asks that if our basic concepts on what it means to be human are wrong then, what is this to mean for our ideas of time, being, consciousness? A critical examination ensues, one informed by a multitude of responses to a large number of philosophers. Under discussion is the mathematical limits as found in (...) Russell, questions on Relativity, Kant's notion of judgement, Popper, Dennett, Dawkins and Proust. He brings into the rapport the concepts of Bergson and their explosive insights into the idea of time. (shrink)

Contextualism is supposed to explain why the following argument for skepticism seems plausible: (1) I don’t know that I am not a bodiless brain-in-a-vat (BIV); (2) If I know I have hands, then I know I am not a bodiless BIV; (3) Therefore, I do not know I have hands. Keith DeRose claims that (1) and (2) are “initially plausible.” I claim that (1) is initially plausible only because of an implicit argument that stands behind it; it is not (...) intuitively plausible. The argument DeRose offers is based on the requirement of sensitivity, that is, on the idea that if you know something then you would not believe it if it were false. I criticize the sensitivity requirement thereby undercutting its support for (1) and the skeptical data that contextualism is meant to explain. While skepticism is not a plausible ground for contextualism, I argue that certain pragmatic considerations are. It’s plausible to think that to know something more evidence is required when more is at stake. The best way to handle skepticism is to criticize the arguments for it. We should not adopt contextualism as a means of accommodating skepticism even if there are other pragmatic reasons for being a contextualist about knowledge. (shrink)

Hacohen’s biography of Popper arrives with the usual effusive praise dominating the dustjacket. This is that rare book which actually justifies commentators’ praise. At 551 pages of text, the book is very large to be concerned with only “formative years.” The length is justified because of the way Hacohen integrates careful historical work with a comprehensive grasp of what is philosophically significant in the life of one of the twentieth century’s most influential philosophers. This book achieves a measure of clarity (...) which most of us desire without achieving, its historical arguments are comprehensively documented, and it advances carefully and persuasively the general thesis that the fullest understanding of the legacy of Sir Karl Popper requires that we understand his roots in fin de siècle Viennese culture. Hacohen’s biography is somewhat different from the style familiar to philosophers from Ray Monk’s works on Wittgenstein and Russell, or Michael Ignatieff’s biography of Berlin. Hacohen’s biography is much less revealing of Popper the man, and much more revealing of social context. Accordingly, those looking for penetrating anecdotes will be disappointed, while those willing to entertain a thorough rereading of Popper will be enthralled. (shrink)

Keith Donnellan (1931 – ) began his studies at the University of Maryland, and earned his Bachelor’s degree from Cornell University. He stayed on at Cornell, earning a Master’s and a PhD in 1961. He also taught at there for several years before moving to UCLA in 1970, where he is currently Emeritus Professor of Philosophy. Donnellan’s work is mainly in the philosophy of language, with an emphasis on the connections between semantics and pragmatics. His most influential work was (...) his 1966 paper “Reference and Definite Descriptions”. In this paper, he challenges the canonical view, due to Bertrand Russell, about definite descriptions. Russell had argued that the proper semantic treatment of a definite description such as “the present king of France” was quantificational. Thus, a sentence like “the present king of France is bald” should be analyzed as “There exists one and only one entity x that is the present king of France, and x is bald”. Donnellan argues that in natural languages, there are actually two different kinds of uses of definite descriptions. Russell’s analysis picks out the “attributive” use of definite descriptions. When we use a definite description (“the F”) this way, we mean to make statements about the unique entity x that is F. However, Donnellan notes that we also sometimes use definite descriptions “referentially” to pick out a given entity and say something about it. To see this, imagine you are at a party where virtually everyone is drinking beer. However, you and your friend are observing a man in a corner of the room holding a martini glass. Unbeknownst to you, the man’s glass is filled with water. You turn to your friend and ask, “who is the man drinking a martini?” Suppose further that your friend knows that the man in question is Fred and that Fred’s glass is filled with water. According to the Russellian attributive analysis, such a question would amount to asking for the identity of the one and only one man drinking a martini. But the presupposition that there is a man drinking a martini is false, and so there should be no answer to the question.. (shrink)

The Introduction to "Knowledge, Number and Reality. Encounters with the Work of Keith Hossack" provides an overview over Hossack's work and the contributions to the volume.

Keith Donnellan wrote his paper on definite descriptions in 1966 at Cornell University, an environment where nearly everybody was discussing Wittgenstein’s ideas of meaning as use. However, his idea of different uses of definite descriptions became one of the fundamental tenets against descriptivism, which was considered one of the main legacies of the Frege–Russell– Wittgenstein view; and I wonder whether a more Wittgensteinian interpretation of Donnellan’s work is possible.

Russell's Principle states that in order to think about an object I must know which thing it is, in the sense of being able to distinguish it from all other things. I show that, contra Strawson, Evans and Cassam, Russell's Principle cannot be applied to first-person thought so as to yield necessary conditions of self-consciousness.

O artigo de Keith S. Donnellan “Reference and Definite Descriptions” (1966) foi escrito com a intenção de mostrar que as teorias de Bertrand Russell e Peter F. Strawson falham por igual em capturar o uso linguístico efetivo das descrições definidas. Contudo, situação se complica para Donnellan à luz do fato de que muitos usos concebíveis de descrições definidas não parecem caber em nenhuma das duas categorias. Há usos que devem ser entendidos antes como motivados pela deferência do que (...) como atributivos, assim como há usos em que variadas falências referenciais cometidas pelos falantes têm como consequência situações em que a descrição simplesmente não dá conta da variedade de possibilidades, vale dizer, casos em que não cabe falar nem em uso referencial nem em uso atributivo. A razão para tanto parece ser a de que dificilmente há um uso atributivo “puro”. As descrições usadas nos exemplos corriqueiros contêm normalmente elementos referenciais, como nomes e indexicais. Quando estes são mal empregados, a insuficiência da distinção de Donnellan é exposta. A segunda tese aqui apresentada é a de que os usos atributivos previstos no artigo clássico de Donnellan se caracterizam por sua natureza inferencial distintiva, com a consequência de que o seu uso atributivo é em geral menos natural e plausível do que o uso referencial.

Colours appear to instantiate a number of structural properties: for instance, they stand in distinctive relations of similarity and difference, and admit of a fundamental distinction into unique and binary. Accounting for these structural properties is often taken to present a serious problem for physicalist theories of colour. This paper argues that a prominent attempt by Byrne and Hilbert to account for the structural properties of the colours, consistent with the claim that colours are types of surface spectral reflectance, is (...) unsuccessful. Instead, it is suggested that a better account of the structural properties of the colours is provided by a form of non-reductive physicalism about colour: a naïve realist theory of colour, according to which colours are superficial mind-independent properties.

This paper has two aims. The first is to use contemporary discussions of naïve realist theories of perception to offer an interpretation of Merleau-Ponty’s theory of perception. The second is to use consideration of Merleau-Ponty’s theory of perception to outline a distinctive version of a naïve realist theory of perception. In a Merleau-Pontian spirit, these two aims are inter-dependent.

`Mr Russell's very brilliant criticism of Leibniz ... is a piece of controversial philosophy as well as a contribution to history.' - Bernard Bosanquet.

Sales professionals have been frequent targets of ethical criticism. This paper reports on a survey on ethics of sales professionals in South Africa. The results revealed salespeoples views on controversial sales practices that involve direct monetary consequences; on practices that adversely affect customers, employers and competitors; and on sales peoples sensitization of ethical issues. Stealing from a competitor at a trade show was viewed as the most unethical of the scenarios, while phone sabotage and lying to a customer were held (...) to be the next most unethical scenarios. Analysis of the results lead to a discussion of the implications for sales management. Ethical perceptions were affected by financial considerations. Marketing and Sales Managers will have to review their approach to training in sales ethics as well as how sales professionals implement the market driven approach. (shrink)

The proper role, if any, for religion-based arguments is a live and sometimes heated issue within the field of bioethics. The issue attracts heat primarily because bioethical analyses influence the outcomes of controversial court cases and help shape legislation in sensitive biopolicy areas. A problem for religious bioethicists who seek to influence biopolicy is that there is now widespread academic and public acceptance, at least within liberal democracies, that the state should not base its policies on any particular religion’s metaphysical (...) claims or esoteric moral system. In response, bioethicists motivated by religious concerns have adopted two identifiable strategies. Sometimes they rely on slippery-slope arguments that, sometimes at least, have empirically testable premises. A more questionable response is the manipulation and misuse of secular-sounding moral language, such as references to “human dignity,” and the plights of groups of people labeled “vulnerable.”.

In this essay, I argue that bioethicists have a thus-far unfulfilled role to play in helping life scientists, including medical doctors and researchers, think about race. I begin with descriptions of how life scientists tend to think about race and descriptions of typical approaches to bioethics. I then describe three different approaches to race: biological race, race as social construction, and race as cultural driver of history. Taking into account the historical and contemporary interplay of these three approaches, I suggest (...) an alternative framework for thinking about race focused on how the idea of race functions socially. Finally, using assisted reproductive technologies as an example, I discuss how bioethicists and scientists might work together using this framework to improve not only their own but broader perspectives on race.

This article demonstrates that non-mechanistic, dynamical explanations are a viable approach to explanation in the special sciences. The claim that dynamical models can be explanatory without reference to mechanisms has previously been met with three lines of criticism from mechanists: the causal relevance concern, the genuine laws concern, and the charge of predictivism. I argue, however, that these mechanist criticisms fail to defeat non-mechanistic, dynamical explanation. Using the examples of Haken et al.’s model of bimanual coordination, and Thelen et al.’s (...) dynamical field model of infant perseverative reaching, I show how each mechanist criticism fails once the standards of Woodward’s interventionist framework are applied to dynamical models. An even-handed application of Woodwardian interventionism reveals that dynamical models are capable of producing genuine explanations without appealing to underlying mechanistic details. 1Introduction2Interventionism and Mechanistic Explanation 2.1Causal relevance and ideal interventions2.2Invariance2.3Explanation3Covering-Laws and Dynamical Explanation 3.1Dynamical models3.2Covering-law explanation3.3Prediction4Causal Relevance 4.1The causal relevance concern4.2Intervening on dynamical models4.3Test case I: The Haken–Kelso–Bunz model4.4Test case II: Dynamical field model5Genuine Laws 5.1The genuine laws concern5.2Using invariance in place of laws5.3Test case I: The Haken–Kelso–Bunz model5.4Test case II: Dynamical field model6Prediction 6.1Predictivism6.2Crude and invariant prediction7Interventionist Criticism of the Haken–Kelso–Bunz Model8Dynamical Explanation8Conclusion.

Core Affect is the neurophysiological state always accessible as simply feeling good or bad, energized or enervated, even if it is not always the focus of attention. Core Affect, alone or more typically combined with other psychological processes, is found in the experiences of feeling, mood and emotion, including the subjective experiences of fear, anger and other so-called basic emotions which are commonly thought to (...) be raw, primitive, and universal.

In this article we explore and contrast the uses and gratifications of the internet for blind/visually impaired and deaf/hearing impaired individuals. The uses and gratifications approach integrates the different issues that surround disabled persons’ internet use into one rich and coherent framework which allows a better understanding of the relationship between benefits obtained from internet use, underlying needs and the barriers that create gaps between gratifications sought and obtained. Based on 21 in-depth interviews, our study shows that both visually and (...) hearing impaired individuals use the internet mostly for gathering information and for communicating with friends and family; meeting new people online was not a priority need. To a great extent these internet uses are driven by the underlying need for independence and active agency. Although our visually and hearing impaired informants share this need, the two groups differ in the gratifications obtained from the internet due to different barriers that hinder their use.

An explanation of the system of textual references employed in this paper may perhaps be of convenience to the reader. As a rule, references to other works have here been incorporated in the main body of the text, with the aid of abbreviations usually derived from the initial letters of the main words in their titles. Thus "HLL, p. 21." refers to page twenty-one of Thomas Hobbes: Leben and Lehre, by F. Tonnies.

The notion of simulation in dreaming of threat recognition and avoidance faces difficulties deriving from (1) some typical characteristics of dream artifacts (some “surreal,” some not) and (2) metaphysical issues involving the need for some representation in the theory of a perspective subject making use of the artifact.
