Great leaders are ethical stewards who generate high levels of commitment from followers. In this paper, we propose that perceptions about the trustworthiness of leader behaviors enable those leaders to be perceived as ethical stewards. We define ethical stewardship as the honoring of duties owed to employees, stakeholders, and society in the pursuit of long-term wealth creation. Our model of relationship between leadership behaviors, perceptions of trustworthiness, and the nature of ethical stewardship reinforces the importance of ethical governance in dealing (...) with employees and in creating organizational systems that are congruent with espoused organizational values.

The discovery of a quaternary complexity limitation to mature cognitive operations raises important theoretical issues. We propose that cognitive limitations arise naturally in a complex dynamic information processing system, and consider problems such as the distinction between parallel and serial processes and the representativeness of the empirical data base used by Halford et al. to support their relational complexity scheme.
When certain formal symbol systems (e.g., computer programs) are implemented as dynamic physical symbol systems (e.g., when they are run on a computer) their activity can be interpreted at higher levels (e.g., binary code can be interpreted as LISP, LISP code can be interpreted as English, and English can be interpreted as a meaningful conversation). These higher levels of interpretability are called "virtual" systems. If such a virtual system is interpretable as if it had a mind, is such a "virtual (...) mind" real? This is the question addressed in this "virtual" symposium, originally conducted electronically among four cognitive scientists: Donald Perlis, a computer scientist, argues that according to the computationalist thesis, virtual minds are real and hence Searle's Chinese Room Argument fails, because if Searle memorized and executed a program that could pass the Turing Test in Chinese he would have a second, virtual, Chinese-understanding mind of which he was unaware (as in multiple personality). Stevan Harnad, a psychologist, argues that Searle's Argument is valid, virtual minds are just hermeneutic overinterpretations, and symbols must be grounded in the real world of objects, not just the virtual world of interpretations. Computer scientist Patrick Hayes argues that Searle's Argument fails, but because Searle does not really implement the program: A real implementation must not be homuncular but mindless and mechanical, like a computer. Only then can it give rise to a mind at the virtual level. Philosopher Ned Block suggests that there is no reason a mindful implementation would not be a real one. (shrink)
When everyone can be a publisher, what distinguishes the journalist? This article considers contemporary challenges to institutional roles in a digital media environment and then turns to three broad journalistic normative values - authenticity, accountability, and autonomy - that affect the credibility of journalists and the content they provide. A set of questions that can help citizens determine the trustworthiness of information available to them emerges from the discussion.
The Knowledge Interchange Format (KIF) [2] is an ASCII- based framework for use in exchanging of declarative knowledge among disparate computer systems. KIF has been widely used in the fields of knowledge engineering and artificial intelligence. Due to its growing importance, there arose a renewed push to make KIF an offi- cial international standard. A central motivation behind KIF standardization is the wide variation in quality, style, and content — of logic-based frameworks being used for knowledge representation. Variations of all (...) three types, of course, hinder the possibility of semantic integration. A well-crafted logic standard for the representation of declarative knowledge would impose some greatly needed syntactic and semantic uniformity on the current somewhat chaotic situation, uniformity that would in turn greatly enhance the capacity for semantic integration. For all its potential advantages, however, the idea of a logic standard is problematic for at least two reasons. (shrink)
Like most religions, the Buddhist tradition is rich in stories that are designed to illustrate key principles and values. Stories of the Buddha himself offer a verbal portrait of an ideal human being that followers of the tradition can aspire to emulate; his story offers a picture of a person with a perfectly healthy mind. Stories of other people (and of gods, ghosts and ghouls) portray a wide range of beings from the nearly perfect to the dreadfully imperfect, all presented (...) as models of what one could eventually become oneself through gradual transformations from one’s present mentality. In what follows, I shall first tell a brief story about myself and will then recount the stories of two men who were cousins with similar but importantly different mentalities. And I shall conclude with a few observations about what I see as the significance of the difference between these two cousins. (shrink)
Everyone, with the possible exception of those who are really good at it, is personally familiar with the phenomenon of self-deception. Anyone who has been conscious of struggling with a temptation to do what goes against her own better judgment and has then found justification for yielding to temptation is familiar with self-deception. So if I may be allowed to begin with the assumption that most of us have experienced a phenomenon that we would identify as some form of self-deception, (...) what I shall try to do in this paper is to examine how one particular theory of personal identity can account for the phenomenon. Having done that, I shall look into the question of one of the mechanisms of self-deception and then into the question of whether there are occasions in which the mechanisms of self-deception may be regarded as producing more positive results.

Background: HIV prevention trials conducted among disadvantaged vulnerable at-risk populations in developing countries present unique ethical dilemmas. A key concern in bioethics is the validity of informed consent for trial participation obtained from research subjects in such settings. The purpose of this study was to investigate the effectiveness of a continuous informed consent process adopted during the MDP301 phase III vaginal microbicide trial in Mwanza, Tanzania. Methods: A total of 1146 women at increased risk of HIV acquisition working as alcohol (...) and food vendors or in bars, restaurants, hotels and guesthouses have been recruited into the MDP301 phase III efficacy and safety trial in Mwanza. During preparations for the trial, participatory community research methods were used to develop a locally-appropriate pictorial flipchart in order to convey key messages about the trial to potential participants. Pre-recorded audio tapes were also developed to facilitate understanding and compliance with gel-use instructions. A comprehension checklist is administered by clinical staff to all participants at screening, enrolment, 12, 24, 40 and 50 week follow-up visits during the trial. To investigate women's perceptions and experiences of the trial, including how well participants internalize and retain key messages provided through a continuous informed consent process, a random sub-sample of 102 women were invited to participate in in-depth interviews (IDIs) conducted immediately after their 4, 24 and 52 week follow-up visits. Results: 99 women completed interviews at 4-weeks, 83 at 24-weeks, and 74 at 52 weeks (a total of 256 interviews). In all interviews there was evidence of good comprehension and retention of key trial messages including that the gel is not currently know to be effective against HIV; that this is the key reason for conducting the trial; and that women should stop using gel in the event of pregnancy. Conclusions: Providing information to trial participants in a focussed, locally-appropriate manner, using methods developed in consultation with the community, and within a continuous informed-consent framework resulted in high levels of comprehension and message retention in this setting. This approach may represent a model for researchers conducting HIV prevention trials among other vulnerable populations in resource-poor settings.Trial registrationCurrent Controlled Trials ISRCTN64716212.

But still I think some account has to be given of the application of CM to tides and cannon balls etc. etc. It seems to me that Einstein's and Bohr's analysis was essentially correct: we make the connection, and thus apply the mathematical statements of CM to macroscopic features of the world about us, by constructing, within the mathematical framework,. macroscopic conglomerates of the elementary particles and fields that should have the general appearance of tides and billiard, looked at from (...) a distance, and that would respond to the probings of mathematical models of measuring devices, whose "pointers" we can see from afar, in the ways that waves and billiard balls do. I think a look at how CM has been used and applied since the time of Newton and Galileo shows that the mathematical theory is linked into our experiences of the world in this nonproblematic way, and that this correspondence at this nonproblematic level is part of classical mechanics in the broad sense in which it is understood by people who use it.

In the interwar period there was a significant school of thought that repudiated Einstein's theory of relativity on the grounds that it contained elementary inconsistencies. Some of these critics held extreme right-wing and anti-Semitic views, and this has tended to discredit their technical objections to relativity as being scientifically shallow. This paper investigates an alternative possibility: that the critics were right and that the success of Einstein's theory in overcoming them was due to its strengths as an ideology rather than (...) as a science. The clock paradox illustrates how relativity theory does indeed contain inconsistencies that make it scientifically problematic. These same inconsistencies, however, make the theory ideologically powerful. The implications of this argument are examined with respect to Thomas Kuhn and Karl Popper's accounts of the philosophy of science. (shrink)
The dramatic increase in the number of overseas students studying in the United Kingdom and other Western countries has required academics to reevaluate many aspects of their own, and their institutions', practices. This article considers differing cultural values among overseas students toward plagiarism and the implications this may have for postgraduate education in a Western context. Based on focus-group interviews, questionnaires, and informal discussions, we report the views of plagiarism among students in 2 postgraduate management programs, both of which had (...) a high constituency of overseas students. We show that plagiarist practices are often the outcome of many complex and culturally situated influences. We suggest that educators need to appreciate these differing cultural assumptions if they are to act in an ethical manner when responding to issues of plagiarism among international students.

Business ethics should be taught in business schools as an integrated part of core curricula in MBA programs with a dual focus on both analytical frameworks and their applications to the business disciplines. To overcome the reluctance of many faculty to handle ethical issues, a critical mass of faculty must develop suitable materials, educate their peers in its use, and take the lead by introducing it in their own courses and on senior management programs.
It is true for many disciplines within the humanities that there are numerous excellent works that introduce the beginner to the basic building blocks of the discipline, and also many advanced studies for the accomplished scholar, but few works that help the student get from the beginning stage to the advanced level. That has certainly been true of the discipline of Sanskrit. Once a student has devoted a couple of years to working through one of the excellent introductions to the (...) language by Ashok Aklujkar, Michael Coulson, Madhav Deshpande, Robert Goldman, or Walter Maurer, there have been hardly any intermediate texts to help the student systematically progress to more advanced levels. Now, however, with the publication of Scholastic Sanskrit, an important step has been taken toward filling that lacuna. This book assumes that the student has learned enough about Sanskrit grammar and syntax to be ready to begin plunging into the vast corpus comprising the many genres of Sanskrit literature. It is built on the conviction that even a student at the early stages of exploring Sanskrit literature can benefit from the work of traditional commentators; it is also built on the observation that until now there have not been reliable guides to help the student make intelligent use of Sanskrit commentaries.

The Madhyamaka school of Buddhism, the followers of which are called Mādhyamikas, was one of the two principal schools of Mahāyāna Buddhism in India, the other school being the Yogācāra. The name of the school is a reference to the claim made of Buddhism in general that it is a middle path (madhyamā pratipad) that avoids the two extremes of eternalism—the doctrine that all things exist because of an eternal essence—and annihilationism—the doctrine that things have essences while they exist but (...) that these essences are annihilated just when the things themselves go out of existence. The conviction of the Madhyamaka school, which can be called the Centrist school in English, is that this middle path is best achieved by a denial that things have any inherent natures at all. All things are, in other words, empty of inherent natures. This doctrine of universal emptiness of inherent natures (svabhāva-śūnyatā) is the hallmark of the school, which places the school solidly in the tradition associated with the Perfection of Wisdom (prajñāpāramitā) literature of Mahāyāna Buddhism.

Writers presenting Buddhism to European and North American audiences have often availed themselves of philosophical terminology from modern traditions to convey presumably less familiar ideas coming from various classical and medieval Asian settings. Since the Buddha and many philosophers who developed his ideas seem to have stressed the importance of practice over theory, Buddhism is frequently described as practical or even pragmatic in its orientation. Since there have been few unpleasant clashes between traditional Buddhist beliefs and the findings of modern (...) science, and nothing that would compare in importance to the confrontations between Darwinians and Creationists, many Buddhist apologists have been able to get away with characterizing theirs as a religion that is scientific in spirit; many Buddhists, especially Therav ¯.

Teaching on social work values is centrally important in social work education as a core aspect of underpinning knowledge in preparing students for practice. This paper describes an innovative project occurring within the first year of the degree in social work, where service users and carers have assisted students with their understanding of social work values. The positive contribution of service users and carers in facilitating students to make links between theory and practice is now well documented. Applying this user (...) perspective to the educational domain of values, however, is relatively uncharted territory given the challenges that have traditionally accompanied the teaching of values. Importantly, this paper describes the ?value talk? which occurred when first-year students sought further meaning from service-user and carer groups in their community settings following classroom teaching on values. The paper not only discusses the detailed preparations involved in the project but also the learning which resulted, drawing on the evaluation findings from the students and participating groups. Whilst the findings show that the students' understanding of social work values has been most significantly influenced by the contributions from service users and carers, it is recognized that further research is needed to monitor the longer term impact on social work students' practice after they qualify.

This paper argues that the inappropriate framing and implementation of plagiarism detection systems in UK universities can unwittingly construct international students as ‘plagiarists’. It argues that these systems are often implemented with inappropriate assumptions about plagiarism and the way in which new members of a community of practice develop the skills to become full members of that community. Drawing on the literature and some primary data it shows how expectations, norms and practices become translated and negotiated in such a way (...) that legitimate attempts to conform with the expectations of the community of practice often become identified as plagiarism and illegitimate attempts at cheating often become obscured from view. It argues that this inappropriate framing and implementation of plagiarism detection systems may make academic integrity more illusive rather than less. It argues that in its current framing – as systems for ‘detection and discipline’ – plagiarism detection systems may become a new micro-politics of power with devastating consequences for those excluded.

Harnad accepts the picture of computation as formalism, so that any implementation of a program - thats any implementation - is as good as any other; in fact, in considering claims about the properties of computations, the nature of the implementing system - the interpreter - is invisible.

Almost all the criticism, claimed refutation by Searle's argument, and sharp contrasting of this idea with others, rests on the absoluteness of this separation between (...) a computational system and its implementation.

Two experiments examined the impact of causal relations between features on categorization in 5- to 6-year-old children and adults. Participants learned artificial categories containing instances with causally related features and noncausal features. They then selected the most likely category member from a series of novel test pairs. Classification patterns and logistic regression were used to diagnose the presence of independent effects of causal coherence, causal status, and relational centrality. Adult classification was driven primarily by coherence when causal links were deterministic (...) (Experiment 1) but showed additional influences of causal status when links were probabilistic (Experiment 2). Children’s classification was based primarily on causal coherence in both cases. There was no effect of relational centrality in either age group. These results suggest that the generative model (Rehder, 2003a) provides a good account of causal categorization in children as well as adults. (shrink)
Buddhism currently enjoys the reputation of being one of the leading voices in a chorus that sings the praises of religious tolerance and perhaps even of pluralism. It is open to question, however, whether this reputation is deserved. The purpose of the present article is to examine whether the teachings of classical Buddhism have a contribution to make to the jubilation over religious pluralism that has become fashionable in some quarters in recent years. It is hoped that this examination might (...) shed some light both on some of the implications of religious pluralism and on the spirit of the teachings of classical Buddhism. A task preliminary to dealing with this question is to clarify what is meant by religious pluralism. For the purpose of this discussion, let us take “pluralism” to signify not the mere acknowledgment that there is variety but the celebration of this variety. Whereas tolerance might be described as the attitude of being resigned to the fact that a variety exists, pluralism will be taken to mean the attitude that variety is healthy and therefore something to be desired. And religious pluralism, of course, will be taken as the attitude that it is salubrious to have a variety of religions. Such an attitude might be founded, for example, on an analogy with biology. The health of each living organism, it could be argued, is enhanced by the general health of the organism’s wider environment, and the health of this wider environment is in turn enhanced by the rich variety of species of organisms living therein. The value of variety, if one follows this biological analogy, is not merely aesthetic, not merely a pleasant respite from the monotony of too much uniformity; rather, variety is what makes life of any kind possible. Similarly, it could be argued by a devoted religious pluralist, the variety of religious beliefs and practices and experiences and modes of expression is vital to human survival and self-understanding. And just as the health of an individual organism, such as a cow, might actually be enhanced by the presence of other apparently annoying organisms, such as gadflies and mosquitoes, the health and perhaps even the very survival of any one religious tradition might actually be enhanced by the presence of other apparently antagonistic traditions, or by the presence of heresies within the same tradition..

Trust is essential in human relationships including those within healthcare. Recent studies have raised concerns about patients’ declining levels of trust. This article will explore the role of trust in decision-making about cardiopulmonary resuscitation (CPR). In this research thirty-three senior doctors, junior doctors and division 1 nurses were interviewed about how decisions are made about providing CPR. Analysis of these interviews identified lack of trust as one cause for poor understanding of treatment decisions and lack of acceptance of medical judgement. (...) Two key implications emerged from the analysis. First, before embarking on a discussion about CPR it is essential to establish trust between the doctor and the patient/family. Secondly, it is essential that the CPR discussion itself does not undermine trust and cause harm to the patient. (shrink)
Religious doctrines and the philosophical arguments supporting them often become more clearly defined as a result of being challenged by opposing views and counterarguments. Conversely, ideas that are never challenged often remain relatively obscure and poorly defined. The process of encountering rival ideas and alternative theories requires people to re-examine their own assumptions and provide reasons for holding views that could previously be taken for granted. It is not surprising, therefore, that a number of important notions within Buddhist philosophy became (...) better defined in the centuries after they became more widely dispersed in the Indian subcontinent; for it was only after coming into contact with opposing theories that many of the ideas articulated by the Buddha, and the presuppositions underlying those ideas, were seriously examined. Once these doctrines were challenged, later Buddhist philosophers had the task of either offering solid arguments in their support or revising the doctrines to a form in which they could be supported. Among the most important doctrines of early Buddhism, and one that remained unexamined for a relatively long time, was the doctrine of rebirth (punarbhava). It appears that most other philosophical systems in India were, like Buddhism, based on the notion that the foremost predicament for all living beings is that they are bound to experience the consequences of actions performed in previous lives; therefore, few philosophers challenged the Buddha in his statement of this as the problem most in need of a solution. Eventually, however, philosophers did arise who began to question the doctrine of rebirth and to pose strong arguments against it. Once this opposition had been stated, it was no longer possible for Buddhist apologists to take the doctrine of rebirth for granted. It became necessary to defend their position by finding evidence in support of it and by finding flaws in the arguments adduced against it. (shrink)

In this essay, I present a dynamic conception of substance beginning with an account of the striving movement of the soul in De Anima.

The (...) striving movement of desire as an efficient cause fulfills a holistic function by providing a teleological unity to the various capacities of the soul. (shrink)

Existence in Black is the first collective statement on the subject of Africana Philosophy of Existence. Drawing upon resources in Africana philosophy and literature, the contributors explore some of the central themes of Existentialism as posed by the context of what Frantz Fanon has identified as "the lived-experience of the black." Among questions posed and explored in the volume are: What is to be done in a world of near universal sense of superiority to, if not universal hatred of, black (...) folk?; What is black suffering?; What is the meaning (if any) of black existence? The introduction argues that a response to these questions requires a journey through the resources of identity questions in critical race theory and the teleological dimensions of liberation theory. The contributors address these questions through an analysis of nearly every dimension of Africana phiosophy. In the first half of the book, they address Black Philosophies of Existence in terms of Traditional African Philosophy, the Harlem Renaissance, Du Boisian Double-Consciousness, and Fanonian and Sartrean Philosophies of Existence. In the second half of the book, contributors consider racial identity through examinations of such concepts as equality, death, mimesis, property, embodiment, technology, disappointment, and dread. Part II is an exploration of postmodern challenges to "black existence" through discussions of postmodern conservatism, Nietzsche's thoughts on blacks, Richard Wright and fragmented consciousness, and feminist critiques of race. And Part IV is an examination of problems of historical responsibility and constructing black liberation theories.

Huntington (2007); argues that recent commentators (Robinson, 1957; Hayes, 1994; Tillemans, 1999; Garfield and Priest, 2002) err in attributing to Nāgārjuna and Candrakīrti a commitment to rationality and to the use of argument, and that these commentators do violence to the Madhyamaka project by using rational reconstruction in their interpretation of Nāgārjuna’s and Candrakīrti’s texts. Huntington argues instead that mādhyamikas reject reasoning, distrust logic and do not offer arguments. He also argues that interpreters ought to recuse themselves from (...) argument in order to be faithful to these texts. I demonstrate that he is wrong in all respects: Nāgārjuna and Candrakīrti deploy arguments, take themselves to do so, and even if they did not, we would be wise to do so in commenting on their texts.

There are numerous occasions on which we need to reason about a finite number of events. And we often need to consider only those events which are given or which we perceive. These give rise to the Criteria of Finiteness and Closedness. Allen's logic provides a way of reasoning about events. In this paper I examine Allen and Hayes' axiomatisation of this logic, and develop two other axiomatisations based on the work by Russell and Thomason. I shall show that (...) these three axiomatisations are weakly equivalent, and that only the last two meet the Criteria of Finiteness and Closedness (to different degrees). I shall then examine two ways of constructing instants of time in a finite and closed world, i.e. the Russell construction and the Thomason construction. I shall prove that these two constructions are equivalent under certain conditions. (shrink)
Hayes & MacEachern’s (1998) study of quatrain stanzas in English folk songs was the first application of stochastic Optimality Theory to a large corpus of data.1 It remains the most extensive study of versification that OT has to offer, and the most careful and perceptive formal analysis of folk song meter in any framework. In a follow-up study, Hayes (2003) concludes that stress and meter — or more generally, the prosodic structure of language and verse — are (...) governed by separate constraint systems which must be jointly satisfied by well-formed verse. Apart from its convincing arguments for a modular approach to metrics, it is notable for successfully implementing the analysis in OT, a framework whose parallelist commitments might seem philosophically at odds with modularity.

In a remarkable confirmation of OT in an empirical domain for which it was not originally intended, phonological and morphological variation has been successfully modeled by partially ranked categorical constraints (Anttila 1997, 2002). Poetic meter is a good place to extend and test this approach to variation, because there is abundant and diverse quantitative data available for it, and because it is typically governed by a relatively small number of well-understood constraints. I report the results of four such studies here. (...) They confirm that choices among metrical options are governed by the interaction of partially ranked constraints, in each case constraints that are grounded, and motivated independently of variation data by related systems in which they have a fixed rank. The partially ranked constraint systems turned out to predict not only the relative preferences among metrical options, but also their actual frequencies in the corpora, with surprising accuracy. These findings support the partial ranking model of variation, and provide an explanatory benchmark beyond the reach of intrinsically weaker stochastic approaches that posit a statistical component for metrical competence (Hayes & MacEachern 1998).

While we agree that the frame problem, as initially stated by McCarthy and Hayes (1969), is a problem that arises because of the use of representations, we do not accept the anti-representationalist position that the way around the problem is to eliminate representations. We believe that internal representations of the external world are a necessary, perhaps even a defining feature, of higher cognition. We explore the notion of dynamically created context-dependent representations that emerge from a continual interaction between working (...) memory, external input, and long-term memory. We claim that only this kind of representation, necessary for higher cognitive abilities such as counterfactualization, will allow the combinatorial explosion inherent in the frame problem to be avoided.

A central goal of contemporary cognitive science is the explanation of cognitive abilities or capacities.

I analyze the frame problem and its relation to other epistemological problems for artificial intelligence, such as the problem of induction, the qualification problem and the "general" AI problem. I dispute the claim that extensions to logic (default logic and circumscriptive logic) will ever offer a viable way out of the problem. In the discussion it will become clear that the original frame problem is really a fairy tale: as originally presented, and as tools for its solution are circumscribed by (...) Pat Hayes, the problem is entertaining, but incapable of resolution. The solution to the frame problem becomes available, and even apparent, when we remove artificial restrictions on its treatment and understand the interrelation between the frame problem and the many other problems for artificial epistemology. I present the solution to the frame problem: an adequate theory and method for the machine induction of causal structure. Whereas this solution is clearly satisfactory in principle, and in practice real progress has been made in recent years in its application, its ultimate implementation is in prospect only for future generations of AI researchers.

For many of the authors in this volume, this is the second attempt to explore what McCarthy and Hayes (1969) first called the “Frame Problem”. Since the first compendium (Pylyshyn, 1987), nicely summarized here by Ronald Loui, there have been several conferences and books on the topic. Their goals range from providing a clarification of the problem by breaking it down into subproblems (and sometimes declaring the hard subproblems to not be the_ real_ Frame Problem), to providing formal “solutions” (...) to certain aspects of the problem. But more often the message has been that the problem is not solvable except in a piecemeal way in special circumstances by some sort of heuristic approximations. It has sometimes also been said that solving the Frame Problem is not only an unachievable goal, but it is also an unnecessary one since_ humans_ do not solve it either; we simply get along as best we can and deal with the problem of planning in ways that, to use Dennett’s phrase, is “good enough for government work”.

The Turing Test (TT) is criticised for various reasons, one being that it is limited to testing only human-like intelligence. We can read, for example, that âTT is testing humanity, not intelligence,â (Fostel, 1993), that TT is âa test for human intelligence, not intelligence in general,â (French, 1990), or that a perspective assumed by TT is parochial, arrogant and, generally, âmassively anthropocentricâ (Hayes and Ford, 1996). This limitation presumably causes a basic inadequacy of TT, namely that it misses a (...) wide range of intelligence by focusing on one possibility only, namely on human intelligence. The spirit of TT enforces making explanations of possible machine intelligence in terms of what is known about intelligence in humans, thus possible specificity of the computer intelligence is ruled out from the oælset.

When certain formal symbol systems (e.g., computer programs) are implemented as dynamic physical symbol systems (e.g., when they are run on a computer) their activity can be interpreted at higher levels (e.g., binary code can be interpreted as LISP, LISP code can be interpreted as English, and English can be interpreted as a meaningful conversation). These higher levels of interpretability are called "virtual" systems. If such a virtual system is interpretable as if it had a mind, is such a "virtual (...) mind" real? This is the question addressed in this "virtual" symposium, originally conducted electronically among four cognitive scientists: Donald Perlis, a computer scientist, argues that according to the computationalist thesis, virtual minds are real and hence Searle's Chinese Room Argument fails, because if Searle memorized and executed a program that could pass the Turing Test in Chinese he would have a second, virtual, Chinese-understanding mind of which he was unaware (as in multiple personality). Stevan Harnad, a psychologist, argues that Searle's Argument is valid, virtual minds are just hermeneutic overinterpretations, and symbols must be grounded in the real world of objects, not just the virtual world of interpretations. Computer scientist Patrick Hayes argues that Searle's Argument fails, but because Searle does not really implement the program: A real implementation must not be homuncular but mindless and mechanical, like a computer. Only then can it give rise to a mind at the virtual level. Philosopher Ned Block suggests that there is no reason a mindful implementation would not be a real one. (shrink)
I argue that the role played by infons in the kind of mathematical theory of information being developed by several workers affiliated to CSLI is analogous to that of the various number systems in mathematics. In particular, I present a mathematical construction of infons in terms of representations and informational equivalences between them. The main theme of the paper arose from an electronic mail exchange with Pat Hayes of Xeroxparc. The exposition derives from a talk I gave at theTheories (...) of Partial Information conference held at the University of Texas at Austin, January 1990. (shrink)
I think that some of the arguments in this article are themselves flawed, or are based on an understanding of linguistics that is too narrowly focused on certain versions of generative grammar. For example, the argument that in computational applications purely statistical approaches are in general more successful than rule-based approaches has to be qualified: It holds, or may have hold, for certain applications like machine translation, but not for others, like the generation of text to answer queries to databases. (...) Furthermore, statistical methods have been integrated in certain linguistic theories themselves, like stochastic optimality theory (Boersma & Hayes 2001). The authors also claim that linguistics is not able to come up with leading questions for the cognitive and neurophysiological investigation of language processing. This statement is even more puzzling, as it is difficult to name serious research in psycholinguistics or in neurophysiological aspects of language processing that is not informed by theoretical notions rooted in linguistics, many of them derived from generative grammar. To cite just one case: Recursion has been proposed – perhaps unjustly so – as the single property that distinguishes human language processing from other animal communication systems; this has led to the identification of special brain regions and pathways of recursive language processing (cf. Friederici 2009). (shrink)
We present a neuro-geometrical model for generating the shape of Kanizsa's modal subjective contours which is based on the functional architecture of the primary areas of the visual cortex. We focus on V1 and its pinwheel structure and model it as a discrete approximation of a continuous fibration π: R × P → P with base space the space of the retina R and fiber the projective line P of the orientations of the plane. The horizontal cortico-cortical connections of V1 (...) implement what the geometers call the contact structure of the fibration π, and defines therefore an integrability condition which can be shown to correspond to Field's, Hayes', and Hess' psychophysical concept of association field. We present then a variational model of curved modal illusory contours (in the spirit of previous models due to Ullman, Horn, and Mumford) based on the idea that virtual contours are “geodetic” integral curves of the contact structure.

This paper develops and extends the concept of ecological identity work through an investigation of issues of identity among students studying the environment at one US university. We conceptualize identity work as both an individual and group process through which students locate themselves in relation to particular, relatively preformed ecological identities, while also attempting to redefine the boundaries of ecological identity itself. Using interview and participant observation data we ask what kinds of ecological identity work takes place among students and (...) who is involved in defining and policing ecological identities. We argue that this approach can contribute to our understanding of the relationship between environmental education, philosophy and action. (shrink)
Compensatory lengthening occurs when the featural content of a nucleus or moraic coda is deleted, or becomes reaffiliated with a nonmoraic position — typically an onset — and the vacated mora, instead of being lost, is retained with new content (Hayes 1989).

Several modern commentators of Dignaga have puzzled over the 5th century Buddhist philosopher1s theory of the triple condition of the inferential sign. Th. Stcherbatsky (1932), Richard Hayes (1988) and Bimal K. Matilal (1986) have wondered at the reasons for Dignaga’s insistence on the inclusion of the secondcondition, which seems to be the logical equivalent of the third condition. Do the three criteria together furnish patterns of valid inference which differ from those patterns furnished by criteria one and three alone? (...) In this paper, I detail three types of cases which underline the importance of the inclusion of the second criterion. (shrink)
The same categorical phenomena which are attributed to hard grammatical constraints in some languages continue to show up as statistical preferences in other languages, motivating a grammatical model that can account for soft constraints. The effects of a hierarchy of person (1st, 2nd 3rd) on grammar are categorical in some languages, most famously in languages withError: Illegal entry in bfrange block in ToUnicode CMap inverse systems, but also in languages with person restrictions on passivization. In Lummi, for example, the person (...) of the subject argument cannot be lower than the person of a nonsubject argument. If this would happen in the active, passivization is obligatory; if it would happen in the passive, the active is obligatory (Jelinek and Demers 1983). These facts follow from the theory of harmonic alignment in OT: constraints favoring the harmonic association of prominent person (1st, 2nd) with prominent syntactic function (subject) are hypothesized to be present as subhierarchies of the grammars of all languages, but to vary in their effects across languages depending on their interactions with other constraints (Aissen 1999). There is a statistical reflection of these hierarchies in English. The same disharmonic person/argument associations which are avoided categorically in languages like Lummi by making passives either impossible or obligatory, are avoided in the SWITCHBOARD corpus of spoken English by either depressing or elevating the frequency of passives relative to actives. The English data can be grammatically analyzed within the stochastic OT framework (Boersma 1998, Boersma and Hayes 2001) in a way which provides a principled and unifying explanation for their relation to the crosslinguistic categorical person effects studied by Aissen (1999).

In 1911, Drs John Freeman and Leonard Noon published an account of a novel treatment for hay fever. Their method of desensitisation consisted of injecting increasing doses of an extract of pollen subcutaneously until the hypersensitivity reaction was diminished or abolished. Over subsequent decades, desensitisation established itself as the cornerstone of clinical allergy in both England and the United States, at least until the advent of novel pharmaceutical agents in the 1950s and 1960s. Although British allergists such as Noon and (...) Freeman were aware of conceptual developments within European immunology and pathology (such as the identification of anaphylaxis by Richet and Portier or von Pirquet's coining of the term allergy), their approach to hay fever was driven by more immediate pragmatic, and indeed financial, considerations. Freeman's immersion in the problems of hay fever and asthma and his pioneering use of allergen desensitisation or immunotherapy were shaped by his adherence to the convictions and bacteriological practices of his principal at St Mary's Hospital, Almroth Wright, and by the drive to produce commercial vaccines which would help to subsidise the experimental and therapeutic work at St Mary's. The aim of this paper is to explore early twentieth-century approaches to hay fever and other allergic diseases by tracing the intellectual and institutional origins of clinical allergy in Britain.

Through the early twentieth century, asthmatics were advised to move to a more suitable climate, or to vacation in one during their worst season. In the late nineteenth century, physicians sought to quantify the ideal temperature, humidity, altitude, and pollen count to help travellers to select a suitable place, but these investigations led some physicians to question contradictions between expected and actual conditions. Given that even the best climate was not perfect at all times, and that many patients could not (...) afford to travel or relocate, a group of physicians-who came to be known as allergists-sought ways to adapt their patients to any climate through changes in their indoor environments and treatments to manage their symptoms. Their approach included changes in household design, furnishings, and cleaning techniques, especially a strict avoidance of dust, which could carry feathers, animal hair, skin debris, pollen, moulds, and an unknown 'dust' allergen. Air filtering and air conditioning were also promoted as ways to protect asthmatics and hay fever sufferers. These modifications of patients and their microenvironments signalled both a move away from climactic approaches to asthma and toward the sanitary, modernist home of the twentieth century. (shrink)
Así como en lo que respecta al análisis político del presente cabe afirmar que no podrá ofrecérsenos éste nunca bajo una figura acabada o una perfecta interrupción en la idealizada plenitud del tiempo, no es menos cierto que hay escrituras y análisis del presente político que persiguen envolver figuras certeras de instantes limitados y, por ello, perfectos. Si el ámbito de la política «exige el presente como tema y problema» (como afirma el autor en su introducción, cf. p. 13), el (...) desafío de la escritura en torno a los problemas filosóficos a través de los cuales pensar certeramente la actualidad de la política puede afrontarse, entre otros lugares, desde la complejidad de la escritura. Así es, hay ensayos en los que se aprecia la voluntad de escritura de su autor, el gusto por una sobriedad que no desdeñe una actitud prolija y generosa —como la del pintor impresionista que pincela sus propias pinceladas para dotarlas de una forma de espesor que sólo cabe adquirir por medio de lo que, en el campo del pensamiento, se llama reflexión— con las posibilidades de la lengua: frases cortas cuyo rigor semántico no radica únicamente en la expresión directa de una idea sino, por ejemplo, en la elección de un verbo que encierre varios sentidos, o en la intercalación de un paréntesis que obligue a deambular al lector hacia el camino opuesto por el que ya marchaba; o bien, por el contrario, inclinándose hacia lo múltiple, el pliegue barroco y la expresión suya bajo subordinadas en las que se hilvana, junto a la idea, un recorrido posible para ésta: diseñado conforme a su complejidad, polisemia, inestabilidad, intempestividad o, incluso, su crudeza y su ironía. A mi modo de ver, Política mente. De la revolución a la globalización da buena cuenta de esa voluntad de estilo. (shrink)
A principios del siglo XIV algunos autores, como Juan de París y Dante, se apoyaron en el aristotelismo para defender la separación del poder religioso y del poder secular. Marsilio de Padua, en cambio, combatió el supremo poder del Papa sobre la base de que no existe poder religioso, porque no hay más que un solo poder: el gobernante civil. El artículo muestra las principales diferencias entre la concepción dualista de los primeros y el monismo marsiliano.
No hay nada más evocador que un cuerpo filmado: los rasgos y la piel, pero también los gestos y movimientos. Y es uno de los privilegios del cine poder llevar a cabo esa misión como ningún otro arte pudo hacerlo antes. Porque a través de las películas vemos la labor del tiempo, su transcurso, su implacable trabajo de demolición. El cine contemporáneo se nos aparece ahora como el laboratorio ideal para la investigación sobre el cuerpo, sobre los contactos que establece (...) con otros cuerpos, sobre sus enfrentamientos, sobre su soledad y su decadencia. Pero también sobre su situación en los nuevos paisajes postindustriales, sobre su relación con la tecnología, sobre las fusiones que se ve obligado a realizar para sobrevivir. No estamos hablando solamente, pues, de relaciones humanas, o de desplazamientos en el espacio, o de las distintas maneras de sonreír y de mover las manos. También hablamos de las nuevas carnes metálicas, de otros cuerpos que hasta ahora nos eran desconocidos, por distancia geográfica o limitaciones de la imaginación. (shrink)
Ortega y Gasset pidió al filósofo la cortesía de la claridad. Las circunstancias del momento presente, en continua transformación, añaden al requerimiento orteguiano otro segundo no menos acuciante: la brevedad. Quien auténticamente sabe algo, acierta a decirlo de forma luminosa y en breve espacio, por ejemplo mil palabras. Y este es el espíritu que anima a Javier Gomá en esta colección de ensayos, o microensayos, que se resume así en su título: Todo a mil. El objetivo es, en un millar (...) de palabras, introducir al lector en la almendra de la reflexión filosófica. Así, por ejemplo, alguno de estos microensayos se arriesgan a definir con precisión cuestiones normalmente difusas como la sabiduría frente a la inteligencia o la dignidad humana; hay unos que abogan por actitudes contracorriente, como los beneficios de estar sentado, el desdén hacia las novedades, las ventajas del chisme o la afirmación gozosa de nuestro tiempo; otros critican ideas recibidas tan asentadas como el prestigio de la transgresión, la noción tradicional de 'vida privada', o la molesta tendencia a la sinceridad excesiva; otros más toman posición respecto a la responsabilidad de la crisis o el significado profundo de la paz social conquistada por el Estado de derecho; mientras otros, en fin, expresan la voz más personal del autor. Con este libro, Javier Gomá da un paso más en su decidida voluntad de hacer una filosofía mundana, abierta a todos, y ofrece así la mejor introducción posible, en mil palabras, a los más serios y perennes problemas filosóficos.

La historia personal y profesional de Carlos París discurre al hilo de la convulsa historia de España del último medio siglo, y la narra con una honestidad de la que muy pocos pueden hacer gala. Así, sin ira y sin tapujos, describe, por ejemplo, cómo pasó de una adhesión inicial a presupuestos falangistas a ser candidato del PCE, valorando cada etapa y cada motivo de cambio con un gran sentido crítico. Por su pluma desfilan también personajes fundamentales en la vida (...) española de los últimos cincuenta años con quienes Carlos París ha tenido una sólida relación, como Manuel Fraga, Javier Solana, Manuel Castells, Rosa Regàs, Ricardo de la Cierva, José Antonio Maravall, José María Valverde, Nicolás Sartorius y un largo etcétera. De la lectura de estas memorias se desprende, en fin, el retrato de una gran figura intelectual y humana que jamás se ha limitado a ser convidado de piedra ni en su país ni en el tiempo que le ha tocado vivir.Carlos París (Bilbao, 1925) es Catedrático Emérito de la Universidad Autónoma de Madrid, en la que fundó su Departamento de filosofía y de cuya Facultad de Filosofía y Letras fue elegido decano en las primeras elecciones. Es Doctor Honoris Causa por la Universidad de Valencia y ha sido Presidente de la Sociedad Española de Filosofía y del Ateneo Científico, Literario y Artístico de Madrid. Su obra ha sido objeto de diversos estudios y congresos internacionales, y recientemente se ha creado un Foro dedicado al análisis y difusión de su pensamiento. Hay que destacar, sobre todo, sus ensayos: Física y filosofía, 1952; Crítica de la civilización nuclear, 1985 o Fantasía y razón moderna-Don Quijote, Odiseo y Fausto, 2001, entre muchos otros; y también sus obras de creación literaria: la novela Bajo constelaciones burlonas (1981) o el libro de relatos La machina speculatrix-Cuatro sarcasmos sobre el mundo actual (1989).

Nuestro tiempo es el de la caída en el presente. Es imposible construir nuevos pactos sociales y, por tanto, las oportunidades para imaginar el futuro son pocas. No hay utopías, sólo un pragmatismo que apuesta por lo útil. Nuestra sociedad sufre el desencanto de la democracia, la lógica del mercado y la globalización, incapaz de producir ideas para el porvenir ¿Cuál es la salida? Richard Rorty diría: no es la razón lo que cambia las cosas, sino la imaginación. A partir (...) de este principio, este libro hace un elogio del optimismo desencantado, donde las preguntas son más importantes que las respuestas ¿Cuál es el papel que las palabras juegan en el actual estado del arte? ¿De qué modo están conectados el mundo y la llamada República de las Letras? ¿Qué idea de generación tienen los escritores nacidos a partir de la década de los setenta? ¿Por qué niegan el concepto de colectivo? ¿Cuál es la relación entre política y literatura? ¿En qué momento el crítico se convirtió en redactor de obituarios? ¿La literatura forma parte del espectáculo? Éste es un ensayo sobre el lenguaje, la idea de generaciones y las estéticas de la literatura contemporánea; pero también es una denuncia que señala los mecanismos que han provocado el distanciamiento entre la creación y la acción, la ética y la estética, la literatura y el espacio público.
