What is the significance of postmodern philosophy for the pursuit of knowledge generally?

Over the last twenty years, John Rawls has developed an approach to political philosophy which appeals to the notion of reflective equilibrium. This notion has proven suggestive to those attracted to coherence approaches to justification, in ethics and in other domains as well. In this paper, I explore the question whether Rawls’s approach provides a model for a coherentist account of justification, concluding that although the discussion of reflective equilibrium has provided helpful insights it has not produced a coherentist model (...) of justification.

Previous research has shown that cognitive style impacts several areas of human behavior of interest to marketers. This article reports the results of an exploratory study testing the proposition that cognitive style can influence one's perceptions of what is and is not a matter of ethics. The findings indicate that cognitive style can play a role in one's perceptions of ethics, and may help further our understanding of the factors that bear on ethical points of view.

The cognitive science student deserves our sympathy. It is difficult to think of another area of study where there is so much disagreement amongst the constituent parts, and even within those parts themselves -- neuroscience, AI, philosophy, psychology, linguistics, quantum and evolutionary theory. To illustrate this difficulty for the erstwhile student, imagine cognitive science as a collection of ball games with mind/brain/ consciousness as the ball. Instead of being able to concentrate on the one game as one might expect to (...) in another subject, the student is faced with a disparate range of disciplines. Some participants maintain it is only they who are playing the real game and that other games should be assimilated to their own. Then there are theorists who like to borrow from a number of games to create their own, whilst others suggest there is no common ground at all between games. We could go on further with this part of the analogy but let us now focus on the ball. Notice how it changes shape, material, size and playing surface from one game to the next -- football, hockey, squash, golf, tennis. Yet at least here the balls are round, the surface solid. How about badminton, rugby and water polo? Hardly surprising then that a cognitive science student needs to have special skills to cope with this confusion. (shrink)

We report two experiments that investigated the widely held assumption that speakers use the addressee’s discourse model when choosing referring expressions (e.g., Ariel, 1990; Chafe, 1994; Givón, 1983; Prince, 1985), by manipulating whether the addressee could hear the immediately preceding linguistic context. Experiment 1 showed that speakers increased pronoun use (and decreased noun phrase use) when the referent was mentioned in the immediately preceding sentence compared to when it was not, even though the addressee did not hear the preceding sentence, (...) indicating that speakers used their own, privileged discourse model when choosing referring expressions. The same pattern of results was found in Experiment 2. Speakers produced more pronouns when the immediately preceding sentence mentioned the referent than when it mentioned a referential competitor, regardless of whether the sentence was shared with their addressee. Thus, we conclude that choice of referring expression is determined by the referent’s accessibility in the speaker’s own discourse model rather than the addressee’s. (shrink)

A key component of research on human sentence processing is to characterize the processing difficulty associated with the comprehension of words in context. Models that explain and predict this difficulty can be broadly divided into two kinds, expectation‐based and memory‐based. In this work, we present a new model of incremental sentence processing difficulty that unifies and extends key features of both kinds of models. Our model, lossy‐context surprisal, holds that the processing difficulty at a word in context is proportional to (...) the surprisal of the word given a lossy memory representation of the context—that is, a memory representation that does not contain complete information about previous words. We show that this model provides an intuitive explanation for an outstanding puzzle involving interactions of memory and expectations: language‐dependent structural forgetting, where the effects of memory on sentence processing appear to be moderated by language statistics. Furthermore, we demonstrate that dependency locality effects, a signature prediction of memory‐based theories, can be derived from lossy‐context surprisal as a special case of a novel, more general principle called information locality.

This article introduces the topic ‘‘Production of Referring Expressions: Bridging the Gap between Computational and Empirical Approaches to Reference’’ of the journal Topics in Cognitive Science. We argue that computational and psycholinguistic approaches to reference production can benefit from closer interaction, and that this is likely to result in the construction of algorithms that differ markedly from the ones currently known in the computational literature. We focus particularly on determinism, the feature of existing algorithms that is perhaps most clearly at (...) odds with psycholinguistic results, discussing how future algorithms might include non-determinism, and how new psycholinguistic experiments could inform the development of such algorithms.

When producing a description of a target referent in a visual context, speakers need to choose a set of properties that distinguish it from its distractors. Computational models of language production/generation usually model this as a search process and predict that the time taken will increase both with the number of distractors in a scene and with the number of properties required to distinguish the target. These predictions are reminiscent of classic findings in visual search; however, unlike models of reference (...) production, visual search models also predict that search can become very efficient under certain conditions, something that reference production models do not consider. This paper investigates the predictions of these models empirically. In two experiments, we show that the time taken to plan a referring expression—as reflected by speech onset latencies—is influenced by distractor set size and by the number of properties required, but this crucially depends on the discriminability of the properties under consideration. We discuss the implications for current models of reference production and recent work on the role of salience in visual search. (shrink)

Methylation of DNA plays an important role in the control of gene expression in higher eukaryotes. This is largely achieved by the packaging of methylated DNA into chromatin structures that are inaccessible to transcription factors and other proteins. Methylation involves the addition of a methyl group to the 5‐position of the cytosine base in DNA, a reaction catalysed by a DNA (cytosine‐5) methyltransferase. This reaction occurs in nuclear replication foci where the chromatin structure is loosened for replication, thereby allowing access (...) to methyltransferases. Partly as a result of their recognising the presence of a methylcytosine on the parental strand following replication, these large enzymes are able to maintain the distribution of methyl groups along the DNA of somatic cells and, thereby, maintain tissue‐specific patterns of gene expression.

This is the third in a series dealing with the concept of self and its importance in understanding Chinese, Japanese, and Indian cultures. The authors examine the relationship between self and image and its significance in attaining a deeper knowledge of Chinese, Japanese, and Indian cultures. The relationship between self and image is as complex as it is fascinating. It takes on different meanings and significances in diverse cultures. In this volume, the focus of attention is largely on representational practices (...) and symbolic media, such as literature, cinema, art, and dance. By examining both classical and contemporary works associated with China, India, and Japan, the authors seek, on the one hand, to demonstrate the intricate relationship between self and image and, on the other, to make use of that relationship to further our understanding of these cultures.

Rule A: if it's metaphysically necessary that p, we may validly infer that no one is even partly morally responsible for the fact that p. Our principal aim in this article is to highlight the importance of this rule and to respond to two recent challenges to it. We argue that rule A is more important to contemporary theories of moral responsibility than has previously been recognized. We then consider two recent challenges to the rule and argue that neither challenge (...) successfully undermines the rule's initial appeal. (shrink)

A philosophy of nursing is to express our considered opinion on what we believe to be true about the nature of the profession of nursing and provide a basis for nursing activities. It affirms the ethical values that we hold as fundamental to our practice. For many of us in nursing, our philosophy derives from Nightingale and phenomenology. We believe Nightingale and phenomenology are uniquely placed within nursing philosophies, to assist the nurse to understand the use of music within a (...) holistic, caring‐healing paradigm, as nursing continues to adapt and evolve in the 21st century. This article proposes that both Nightingale's environmental philosophy and phenomenology are excellent intellectual and practice frameworks for nurses to consider music‐based interventions for older adults who experience dementia. The potential outcome is an enhanced understanding of the well‐being of this vulnerable group of older persons. (shrink)

Objectives – To propose a neuropsychological study of the various aspects of self-consciousness (SC) in Alzheimer’s disease. Methods – Forty-five patients with probable mild or moderate AD were included in the study. Severity of their dementia was assessed by the Mini Mental State (MMS). Fourteen questions were prepared to evaluate SC. Results – No (...) significant correlations were found between SC score and educational level, age, and duration of disease. A significant correlation was found between SC score and the severity of dementia, whereas frontal disturbances were just short of the significance threshold. The various aspects of SC were not impaired to the same degree. The most disturbed ones were awareness of cognitive deficiencies, moral judgements and prospective memory. The least disturbed aspects were awareness of identity and of mental representation of the body. Items relating to anosognosia and moral judgements were significantly correlated with the MMS score, whereas affective state, body representation disorders, prospective memory, and capacities for introspection were not related to the severity of the dementia. Consciousness of identity was sound, regardless of MMS score. Conclusions – AD clearly induces an heterogeneous impairment of SC. SC requires a convergence of many neural networks. In AD, neuronal alterations involve many cortical areas and information sent to the associative frontal cortex from memory, language and visuospatial areas is lacking or disturbed. Thus, the sequential order of successive stimuli cannot be maintained by the heteromodal associative cortex (dorsal convexity of the prefrontal cortex), and the supramodal associative cortex (located rostrally in the frontal lobes) is unable to provide reliable monitoring and assessment of simultaneous neural cognitive networks carrying insufficient and inadequate input. The core deficiency in AD patients might be impaired SC equated with the disability to maintain sequential and simultaneous ‘‘attention to life’’. The Self-Consciousness Questionnaire, a clinical scale providing multidimensional measurement, indicates that different aspects of consciousness are not correlated with overall cognitive deficiency as determined by the MMSE.

The so-called Direct Argument for the incompatibility of moral responsibility and causal determinism depends on a rule of inference called Rule A, a rule that says no one is even partly morally responsible for a necessary truth. While most philosophers think that Rule A is valid, Stephen Kearns has recently offered several alleged counterexamples to the rule. In the paper, I show that Kearns’ counterexamples are unsuccessful.

Most philosophers who study moral responsibility have done so in isolation of the concept of truth. Here, I show that thinking about the nature of truth has profound consequences for discussions of moral responsibility. In particular, by focusing on the very trivial nature of truth—that truth depends on the world and not the other way around—we can see that widely accepted counterexamples to one of the most influential incompatibilist arguments can be shown not only to be false, but also impossible.

In recent work, W. Matthews Grant challenges the common assumption that if humans have libertarian free will, and the moral responsibility it affords, then it is impossible for God to cause what humans freely do. He does this by offering a “non-competitivist” model that he calls the “Dual Sources” account of divine and human causation. Although we find Grant’s Dual Sources model to be the most compelling of models on offer for non-competitivism, we argue that it fails to circumvent a (...) theological version of Peter van Inwagen’s direct argument for incompatibilism. In the paper, we motivate and deploy a theological take on the direct argument, and we contend that this theological rendition of the direct argument effectively dismantles Grant’s Dual Sources account of non-competitivism.
