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.

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

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)

Caste and Buddhist Philosophy: Continuity of Some Buddhist Arguments against the Realist Interpretation of Social Denominations. By Vincent Eltschinger.

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)

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)

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.

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.

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)

The modal version of the ontological argument (MOA) for God’s existence is controversial, primarily, at its first premise, the premise that reads “possibly, there exists a maximally great being.” So, what’s needed is an argument for the possibility of a maximally great being, a being that is omnipotent, omniscient, morally perfect, has these properties essentially, and is such that it exists necessarily. Ironically, I think that such an argument can be found in the literature on the problem of evil, literature (...) generally devoted to arguments against God’s existence. In particular, I argue that Alvin Plantinga’s “free will defense” (FWD) gives us such an argument. Moreover, since most philosophers agree that the FWD is successful, I argue that most philosophers should agree that FWD gives us a successful argument for the first premise of MOA. Thus, I argue that if most philosophers agree FWD is successful, then most philosophers should agree that God exists. There are several pressing objections to this line of reasoning that I consider in the paper. I argue that these objections fail. (shrink)

In his “Plantinga on Exclusivisim,” Richard Feldman argues that Alvin Plantinga, in an earlier paper, has not sufficiently addressed a particular problem for the religious exclusivist. The particular problem that Feldman thinks Plantinga has failed sufficiently to address is the problem of epistemic peer disagreement—that is, disagreement between two (or more) equally competent thinkers who share equally good reasons for, and are in equally good epistemic situations regarding, their contradictory beliefs—in matters of religious belief. To demonstrate that Plantinga has so (...) failed, Feldman introduces a principle, ‘B’, that purports to show that exclusivism (religious or not) tends to lead to unjustified beliefs. But I think that Feldman has failed successfully to show that B demonstrates exclusivism’s tendency to lead to unjustified beliefs; so, in the paper, I defend Plantinga, and the exclusivist more generally, from Feldman’s criticisms.

More than 200 million children under the age of 5 years are affected by malnutrition worldwide according to the World Health Organization. The Barbados Nutrition Study (BNS) is a 55-year longitudinal study on a Barbadian cohort with histories of moderate to severe protein-energy malnutrition (PEM) limited to the first year of life and a healthy comparison group. Using quantitative electroencephalography (EEG), differences in brain function duringchildhood(lower alpha1 activity and higher theta, alpha2 and beta activity) have previously been highlighted between participants (...) who suffered from early PEM and controls. In order to determine whether similar differences persisted intoadulthood, our current study used recordings obtained during a Go-No-Go task in a subsample of the original BNS cohort [population size (N) = 53] at ages 45–51 years. We found that previously malnourished adults [sample size (n) = 24] had a higher rate of omission errors on the task relative to controls (n= 29). Evoked-Related Potentials (ERP) were significantly different in participants with histories of early PEM, who presented with lower N2 amplitudes. These findings are typically associated with impaired conflict monitoring and/or attention deficits and may therefore be linked to the attentional and executive function deficits that have been previously reported in this cohort in childhood and again in middle adulthood.
