This article deals with the methodologies commonly used in the framework of the structural approach to social representations. It concerns free and hierarchical evocations, the characterization questionnaire, the similarity analysis, the basic cognitive schemes model, the attribute-challenge technique and the test of context independence. More than a simple review of these methodologies, it offers a critical approach concerning the problems encountered and related to: thresholds or “cutoff points” used to diagnose the structure and the accuracy of the structural diagnosis, grouping (...) methods employed to reduce the corpus of verbal associations, the dilemma between reliability and feasibility, especially in field research, the adequacy and number of modalities of response in the framework of the structural diagnosis. Following this evaluation, this article suggests potential solutions to overcome these methodological limitations. Moreover, as methodological issues are closely related to theoretical questions, the link between social representation theory and identity approaches is discussed. (shrink)

Vagueness is given a philosophically neutral definition in terms of an epistemic notion of tolerance. Such a notion is intended to capture the thesis that vague terms draw no known boundary across their range of signification and contrasts sharply with the semantic notion of tolerance given by Wright (1975, 1976). This allows us to distinguish vagueness from superficially similar but distinct phenomena such as semantic incompleteness. Two proofs are given which show that vagueness qua epistemic tolerance and vagueness qua borderline (...) cases (when properly construed to exclude terms which are stipulated to give rise to borderline cases) are in fact conceptually equivalent dimensions of vagueness, contrary to what might initially be expected. It is also argued that the common confusion of tolerance and epistemic tolerance has skewed the vagueness debate in favour of indeterminist over epistemic conceptions of vagueness. Clearing up that confusion provides an indirect argument in favour of epistemicism. Finally, given the equation of vagueness with epistemic tolerance, it is shown that there must be radical higher-order vagueness, contrary to what many authors have argued. (shrink)

We model scientific theories as Bayesian networks. Nodes carry credences and function as abstract representations of propositions within the structure. Directed links carry conditional probabilities and represent connections between those propositions. Updating is Bayesian across the network as a whole. The impact of evidence at one point within a scientific theory can have a very different impact on the network than does evidence of the same strength at a different point. A Bayesian model allows us to envisage and analyze the (...) differential impact of evidence and credence change at different points within a single network and across different theoretical structures.

We argue that all human beings have a special type ofdignitywhich is the basis for (1) the obligation all of us have not to kill them, (2) the obligation to take their well‐being into account when we act, and (3) even the obligation to treat them as we would have them treat us, and indeed, that all human beings areequalin fundamental dignity. We give reasons to oppose the position that only some human beings, because of their possession of certain characteristics (...) in addition to their humanity (for example, an immediately exercisable capacity for self‐consciousness, or for rational deliberation), have full moral worth. What distinguishes human beings from other animals, what makes human beingspersonsrather thanthings, is their rational nature, and human beings are rational creatures by virtue of possessing natural capacities for conceptual thought, deliberation, and free choice, that is, the natural capacity to shape their own lives.

ABSTRACT This article defends the following argument: what makes you and I valuable so that it is wrong to kill us now is what we are (essentially). But we are essentially physical organisms, who, embryology reveals, came to be at conception/fertilisation. I reply to the objection to this argument (as found in Dean Stretton, Judith Thomson, and Jeffrey Reiman), which holds that we came to be at one time, but became valuable as a subject of rights only some time later, (...) in virtue of an acquired characteristic. I argue against this position that the difference between a basic, natural capacity and some degree of development of such a capacity is a mere difference in degree, that this position logically implies the denial of equal personal dignity, and that the selection of the required degree of development of a capacity is necessarily arbitrary.

A small consortium of philosophers has begun work on the implications of epistemic networks (Zollman 2008 and forthcoming; Grim 2006, 2007; Weisberg and Muldoon forthcoming), building on theoretical work in economics, computer science, and engineering (Bala and Goyal 1998, Kleinberg 2001; Amaral et. al., 2004) and on some experimental work in social psychology (Mason, Jones, and Goldstone, 2008). This paper outlines core philosophical results and extends those results to the specific question of thresholds. Epistemic maximization of certain types does show (...) clear threshold effects. Intriguingly, however, those effects appear to be importantly independent from more familiar threshold effects in networks. (shrink)

Cet article étudie le renouvellement de sens que Nietzsche fait subir à la notion de scepticisme. Il part de la double appréciation déroutante du scepticisme grec, loué pour la probité intellectuelle de son ephexis et critiqué simultanément comme une forme de nihilisme de type bouddhiste préservant les valeurs ascétiques, pour montrer que le scepticisme évoqué par la formule « les grands esprits sont des sceptiques. Zarathoustra est un sceptique » renvoie au « frédéricisme » ( Par-delà bien et mal ), (...) c ’ est-à-dire à une expérimentation pratique – audacieuse et dangereuse – menée sur les valeurs. (shrink)

For more than 20 years, research has proven the beneficial effect of natural frequencies when it comes to solving Bayesian reasoning tasks (Gigerenzer & Hoffrage, 1995). In a recent meta-analysis, McDowell & Jacobs (2017) showed that presenting a task in natural frequency format increases performance rates to 24% compared to only 4% when the same task is presented in probability format. Nevertheless, on average three quarters of participants in their meta-analysis failed to obtain the correct solution for such a task (...) in frequency format. In this paper, we present an empirical study on what participants typically do wrong when confronted with natural frequencies. We found that many of them did not actually use natural frequencies for their calculations, but translated them back into complicated probabilities instead. This switch from the intuitive presentation format to a less intuitive calculation format will be discussed within the framework of psychological theories (e.g., the Einstellung effect). (shrink)

Husserl argues in the Crisis that the prevalent tradition of positive science in his time had a philosophical core, called by him "Galilean science", that mistook the quest for objective theory with the quest for truth. Husserl is here referring to Gottingen science of the Golden Years. For Husserl, theory "grows" out of the "soil" of the prescientific, that is, pretheoretical, life-world. Scientific truth finally is to be sought not in theory but rather in the pragmatic-perceptual praxes of measurement. Husserl (...) is faulted for taking measuring processes to be "infinitely perfectible". The dependence of new scientific phenomena on the existence of prior "prescientific" inductive praxis is analyzed, also Husserl's residual objectivism and failure to appreciate the hermeneutic character of measurement. Though not a scientific (theory-)realist, neither was he an instrumentalist, but he was a scientific (phenomena-)realist. (shrink)

Up to now theories of semantic information have implicitly relied on logical monism, or the view that there is one true logic. The latter position has been explicitly challenged by logical pluralists. Adopting an unbiased attitude in the philosophy of information, we take a suggestion from Beall and Restall at heart and exploit logical pluralism to recognise another kind of pluralism. The latter is called informational pluralism, a thesis whose implications for a theory of semantic information we explore.

The central role of corporate leaders in setting the ethical tone for their organization is widely accepted. Four well known former CEOs are profiled to illustrate how their managerial ethical leadership not only influenced their firms but also the practice of business. Insights are drawn from their writings and speeches as well as other sources which examine demonstrated leadership abilities. Their behavior not only provides examples of leadership but also is exemplary from an ethical point of view. The article concludes (...) with five common themes that describe these individuals and the essence of managerial ethical leadership. (shrink)

The iterated Prisoner’s Dilemma has become the standard model for the evolution of cooperative behavior within a community of egoistic agents, frequently cited for implications in both sociology and biology. Due primarily to the work of Axelrod (1980a, 198Ob, 1984, 1985), a strategy of tit for tat (TFT) has established a reputation as being particularly robust. Nowak and Sigmund (1992) have shown, however, that in a world of stochastic error or imperfect communication, it is not TFT that finally triumphs in (...) an ecological model based on population percentages (Axelrod and Hamilton 1981), but ‘generous tit for tat’ (GTFT), which repays cooperation with a probability of cooperation approaching 1 but forgives defection with a probability of l/3. In this paper, we consider a spatialized instantiation of the stochastic Prisoner’s Dilemma, using two-dimensional cellular automata (Wolfram, 1984, 1986; Gutowitz, 1990) to model the spatial dynamics of populations of competing strategies. The surprising result is that in the spatial model it is not GIFT but still more generous strategies that are favored. The optimal strategy within this spatial ecology appears to be a form of ‘bending over backwards’, which returns cooperation for defection with a probability of 2/3 - a rate twice as generous as GTFT.

Social entrepreneurship activity continues to surge tremendously in market and economic systems around the world. Yet, social entrepreneurship theory and understanding lag far behind its practice. For instance, the nature of the entrepreneurial discovery phenomenon, a critical area of inquiry in general entrepreneurship theory, receives no attention in the specific context of social entrepreneurship. To address the gap, we conceptualize social entrepreneurial discovery based on an extension of corporate social responsibility into social entrepreneurship contexts. We develop a model that emphasizes (...) mobilization and timing as underpinnings of social entrepreneurial discovery and offer distinct conceptual aspects and theoretic propositions instrumental to future social entrepreneurship research.

Let R(X, B) denote the class of probability functions that are defined on algebra X and that represent rationally permissible degrees of certainty for a person whose total relevant background evidence is B. This paper is concerned with characterizing R(X, B) for the case in whichX is an algebra of propositions involving two properties and B is empty. It proposes necessary conditions for a probability function to be in R(X, B), some of which involve the notion of statistical dependence. The (...) class of probability functions that satisfy these conditions, here denoted PI, includes a class that Carnap once proposed for the same situation. Probability functions in PI violate Carnap's axiom of analogy but, it is argued, that axiom should be rejected. A derivation of Carnap's model by Hesse has limitations that are not present in the derivation of PI given here. Various alternative probability models are considered and rejected. (shrink)

Tschacher and Haken have recently applied a systems-based approach to modeling psychotherapy process in terms of potentially beneficial tendencies toward deterministic as well as chaotic forms of change in the client’s behavioral, cognitive and affective experience during the course of therapy. A chaotic change process refers to a greater exploration of the states that a client can be in, and it may have a potential positive role to play in their development. A distinction is made between on the one hand, (...) specific instances of instability which are due to techniques employed by the therapist, and on the other, a more general instability which is due to the therapeutic relationship, and a key, necessary result of a successful therapeutic alliance. Drawing on Friston’s systems-based model of free energy minimization and predictive coding, it is proposed here that the increase in the instability of a client’s functioning due to therapy can be conceptualized as a reduction in the precisions with which the client’s prior beliefs about themselves and their world, are held. It is shown how a good therapeutic alliance results in the emergence of a new hierarchical level in the client’s generative model of themselves and their relationship with the world. The emergence of this new level of functioning permits the reduction of the precisions of the client’s priors, which allows the client to ‘open up’: to experience thoughts, emotions and experiences they did not have before. It is proposed that this process is a necessary precursor to change due to psychotherapy. A good consilience can be found between this approach to understanding the role of the therapeutic alliance, and the role of epistemic trust in psychotherapy as described by Fonagy and Allison. It is suggested that beneficial forms of instability in clients are an underappreciated influence on psychotherapy process, and thoughts about the implications, as well as situations in which instability may not be beneficial for therapy, are considered.

In a series of formal studies and less formal applications, Hong and Page offer a ‘diversity trumps ability’ result on the basis of a computational experiment accompanied by a mathematical theorem as explanatory background (Hong & Page 2004, 2009; Page 2007, 2011). “[W]e find that a random collection of agents drawn from a large set of limited-ability agents typically outperforms a collection of the very best agents from that same set” (2004, p. 16386). The result has been extremely influential as (...) an epistemic justification for diversity policy initiatives. Here we show that the ‘diversity trumps ability’ result is tied to the particular random landscape used in Hong and Page’s simulation. We argue against interpreting results on that random landscape in terms of ‘ability’ or ‘expertise.’ These concepts are better modeled on smother and more realistic landscapes, but keeping other parameters the same those are landscapes on which it is groups of the best performing that do better. Smoother landscapes seem to vindicate both the concept and the value of expertise. Change in other parameters, however, also vindicates diversity. With an increase in the pool of available heuristics, diverse groups again do better. Group dynamics makes a difference as well; simultaneous ‘tournament’ deliberation in a group in place of the ‘relay’ deliberation in Hong and Page’s original model further emphasizes an advantage for diversity. ‘Tournament’ 2 dynamics particularly shows the advantage of mixed groups that include both experts and non-experts. As a whole, our modeling results suggest that relative to problem characteristics and conceptual resources, the wisdom of crowds and the wisdom of the few each have a place. We regard ours as a step toward attempting to calibrate their relative virtues in different modelled contexts of intellectual exploration. (shrink)

L’analyse menée par Nietzsche dans le second traité des Éléments pour la généalogie de la morale ne se heurte-t-elle pas à une sourde contradiction? Bien qu’il rejette l’idée de contrat comme modèle pour comprendre la genèse de l’État, c’est en effet sur cette notion que semble reposer toute la logique argumentative du traité. C’est sur cette tension interne que se penche le présent article, qui s’efforce de la résoudre en réexaminant le statut exact que Nietzsche prête au schéma contractuel.

Cette étude part du privilège accordé par Nietzsche au problème de la hiérarchie, et à l'idée de commandment, qui peuvent sembler de préjugés. Elle en interroge la significations et montre qu'ils se justifient pas ni par la condamnation de la croyance, ni par la valorisation du philosophe comme esprit libre, mais par la logiqu de la vie pulsionnelle, qui repose intégralement sur la relation de commandment et d'obéissance. Cette dernière est par conséquent reconnue pour la logique qui structure la réalité (...) tout entière.Die Studie geht vom Vorrang des Problems der Rangordnung bei Nietzsche und des Gedankens des Befehlens aus, die als bloße vorurteile seinerseits erscheinen können. Sie fragt nach ihrer bedeutung und zeigt, dass sie sich weder durch die Verurteilung des Glaubens noch durch die Hochschätzung des Philsophen als freien Geistes, sondern durch die Logik des Trieblebens rechtfertigen, die völlig auf dem Verhälnis von Befehl und Gehorsam beruht. Nietzsche erkennt in ihm die Logik, die Realität im ganzen strukturiert.This paper starts from the priority Nietzsche attaches to the problem of hierarchy and to the idea of command, which may seem to be prejudices. it analyzes tehir meanings, and shows their justifications are not based on the ruling out of belief, nor on the praise of the philosopher as a free spirit, but on the logic of drives, which rests wholly on the command/obedience relationship. The latter should therefore be recognized as the logic organizing the whole of reality. (shrink)

Le propos de cet article est d’interroger l’usage déroutant de la première personne chez Nietzsche, qui semble tout à la fois, en introduisant des notations biographiques, constituer une entorse à l’analyse philosophique et entrer en contradiction avec son rejet de la réalité du moi. À l’examen, il s’avère que ces textes n’ont pas pour fonction de renvoyer à une unité empirique, mais doivent se comprendre comme le signe d’un problème que la philosophie bien entendue doit affronter, à savoir le défi (...) constitué par l’aptitude à évaluer les valeurs. Sous cet angle, l’écriture à la première personne ne vise pas la mise en avant d’un modèle qu’il s’agirait pour les penseurs d’imiter, mais a pour objet, tout au contraire, de révéler la situation atypique qui confère à Nietzsche un privilège quant à l’entreprise philosophique : l’étendue du spectre pulsionnel qui le caractérise, lui permettant de connaître et d’apprécier une vaste série de conditions d’existence, de la maladie à la santé.

Sur quelles raisons Nietzsche fonde-t-il sa critique de la vérité et quelles en sont les retombées pour la caractérisation de la pratique philosophique? La découverte d'un antagonisme entre pensée et verité établit que l'irréfutable n'est pas assimilable au vrai, et en quoi la vérité est interprétation. Se révèle alors son statut de valeur, ainsi que la logique d'incorporation dont elle relève, qui en fait un genre d'erreur devenu pour nous indispensable. À titre de conséquence, la philosophie ne peut plus se (...) comprendre comme recherche de la vérité, mais bien plutôt comme interrogation sur la valeur de cette valeur et création de « vérités » nouvelles. Le philosophe authentique, esprit libre, est alors à penser comme amateur d' énigmes, sur un modèle épicurien et non plus platonicien. What are Nietzsche's reasons for criticizing truth, and how does he understand the consequences of his position for the philosophical praxis? The discovery of the opposition of truth and thought shows that being irrefutable cannot be assimilated to being true, and that truth is interpretation. It appears therefore to be a value, a type of error which has become essential for us, linked to a process of physical-psychological absorption. As a consequence, philosophy cannot be equated with the pursuit of truth any longer ; its aim is to investigate the value of this particular value, and to create new « truths ». Being a free spirit, the genuine philosopher is to be thought of as a lover of riddles, shaped on Epicure's pattern rather than on Plato's. (shrink)

Complexe, énigmatique car radicalement novatrice, la pensée nietzschéenne donne le sentiment d'être trop dispersée pour pouvoir être saisissable. Du reste, y a-t-il un ou plusieurs Nietzsche? Celui de L'Antéchris et d'Ecce Homo est-il le même que celui de La Naissance de la tragédie? Mais complexe ne signifie pas chaotique, et l'incertitude se dissipe si l'on repère les moments où se constituent ses positions fondamentales: quand la notion de pulsion se met-elle en place? Avec quel ouvrage la théorie des valeurs apparaît-elle? (...) À quel moment la logique du sentiment de puissance est-elle identifiée? Quand la philosophie est-elle comprise comme un dire-oui? Dans quel livre la tentative de lire la réalité tout entière comme volonté de puissance se fait-elle jour? Cet ouvrage apporte une réponse à ces questions. Il caractérise l'apport des principaux textes de Nietzsche, et montre que l'évolution de sa réflexion n'est pas faite de revirements ni d'abandons de thèses au profit de thèses nouvelles, mais d'un affinement progressif au sein d'une problématique invariante: conquête d'un mode de pensée réformé dont les grandes lignes sont dessinées dès son premier livre, La Naissance de la tragédie"--Page 4 of cover.

Humean instrumentalism is the view that all of one’s reasons for action are ultimately grounded in one’s antecedent desires, whatever those happen to be. According to this view, what determines which actions are rational is ultimately what the agent wants or desires, while the role of rational deliberation is to inform the agent about how to best gratify these desires. In this paper I aim to weaken commitment to Humean instrumentalism by showing that (a) the main supporting argument for HI (...) fails and that (b) Humean instrumentalism conflicts with a very plausible principle of practical rationality.

The Law of Non-Contradiction holds that both sides of a contradiction cannot be true. Dialetheism is the view that there are contradictions both sides of which are true. Crucial to the dispute, then, is the central notion of contradiction. My first step here is to work toward clarification of that simple and central notion: Just what is a contradiction?

This study argues that the notion of transparency requires reconsideration as an essence of ethical agency. It provides a brief explication of the concept of transparency, rooted in the principle of human dignity of Immanuel Kant, and suggests that it has been inadequately appreciated by media ethics scholars and instructors more focused on relatively simplistic applications of his categorical imperative. This study suggests that the concept's Kantian roots raise a radical challenge to conventional understandings of human interaction and, by extension, (...) what it means to exercise freedom.

We work with a large spatialized array of individuals in an environment of drifting food sources and predators. The behavior of each individual is generated by its simple neural net; individuals are capable of making one of two sounds and are capable of responding to sounds from their immediate neighbors by opening their mouths or hiding. An individual whose mouth is open in the presence of food is “fed” and gains points; an individual who fails to hide when a predator (...) is present is “hurt” by losing points. Opening mouths, hiding, and making sounds each exact an energy cost. There is no direct evolutionary gain for acts of cooperation or “successful communication” per se. In such an environment we start with a spatialized array of neural nets with randomized weights. Using standard learning algorithms, our individuals “train up” on the behavior of successful neighbors at regular intervals. Given that simple setup, will a community of neural nets evolve a simple language for signaling the presence of food and predators? With important qualifications, the answer is “yes.” In a simple spatial environment, pursuing individualistic gains and using partial training on successful neighbors, randomized neural nets can learn to communicate.

This paper aims to clarify Schopenhauer’s a priori argument for pessimism and, to an extent, rescue it from standard objections in secondary literature. I argue that if we separate out the various strands of Schopenhauer’s pessimism, we hit upon problems and counterexamples stemming from psychology. For example, instances where striving does not appear to equate to suffering, which puts pressure on the Schopenhauerian claim that human life, qua instantiation of the will, is painful. Schopenhauer’s sensitivity to the complexities of human (...) psychology means that he may be able to stave off such concerns. However, this reveals that true force of Schopenhauer’s argument lies in the manner in which he combines an a priori formulation with empirical observation. I conclude that, though not unproblematic, Schopenhauer’s argument in its most refined forms offers a deep articulation of the human condition, and warrants serious consideration. (shrink)

We are increasingly exposed to polarized media sources, with clear evidence that individuals choose those sources closest to their existing views. We also have a tradition of open face-to-face group discussion in town meetings, for example. There are a range of current proposals to revive the role of group meetings in democratic decision-making. Here, we build a simulation that instantiates aspects of reinforcement theory in a model of competing social influences. What can we expect in the interaction of polarized media (...) with group interaction along the lines of town meetings? Some surprises are evident from a computational model that includes both. Deliberative group discussion can be expected to produce opinion convergence. That convergence may not, however, be a cure for extreme views polarized at opposite ends of the opinion spectrum. In a large class of cases, we show that adding the influence of group meetings in an environment of self-selected media produces not a moderate central consensus but opinion convergence at one of the extremes defined by polarized media.

What constitutes better schooling for today's youth? In 1984 educational theorist Theodore R. Sizer formulated nine Common Principles to answer this question and launched The Coalition of Essential Schools, an organization of schools attempting to change their own structure, curriculum, pedagogy, and power relations according to Sizer's Principles. This important book, the first comprehensive look at Coalition schools, charts the course of reform at eight charter member schools. The Coalition now counts over 900 private, parochial, public, urban, suburban, and rural (...) secondary schools among its affiliates nationwide. Donna E. Muncey and Patrick J. McQuillan, experts in anthropology as well as education, conducted a five-year ethnographic study to understand what happened in Coalition schools. The authors looked at curricular and pedagogical developments; how changes affected individual students, teachers, administrators, and other school personnel; and how American cultural beliefs influenced efforts to change. The schools' reform experiences differed: some efforts were sustained when others stalled, change divided some faculties while others found a sense of shared purpose, and the principals of some schools facilitated change while others clearly inhibited it. This compelling book, written for all who are concerned with education in America, offers a wealth of insights into the complexities of change efforts in individual schools and in classrooms.

This article aims to elucidate and explore the significance of a distinction in Schopenhauer's pessimism which has not yet received detailed attention in the secondary literature. Schopenhauer is well known to have argued for the thesis that the fundamental feature of sentient life is pervasive suffering, and on these grounds held that individual lives are not worth living. However, he similarly claims with frequency that the nonexistence of the world “as a whole” is preferable to its existence. This is a (...) distinct thesis, and it is unclear how Schopenhauer thinks it relates to the first. This investigation seeks to rectify this, arguing that the ambiguous concept of the world “as a whole” has at least two interpretations in Schopenhauer's texts. Moreover, that this “world-pessimism”—once properly understood—may avoid certain objections that pessimism at the level of the individual is vulnerable to. (shrink)

Variations on the ontological argument for most minimal and most mediocre beings.

Many of the formalisms used in Attribute Value grammar are notational variants of languages of propositional modal logic, and testing whether two Attribute Value Structures unify amounts to testing for modal satisfiability. In this paper we put this observation to work. We study the complexity of the satisfiability problem for nine modal languages which mirror different aspects of AVS description formalisms, including the ability to express re-entrancy, the ability to express generalisations, and the ability to express recursive constraints. Two main (...) techniques are used: either Kripke models with desirable properties are constructed, or modalities are used to simulate fragments of Propositional Dynamic Logic. Further possibilities for the application of modal logic in computational linguistics are noted. (shrink)

Let us sum up. The paradox of the Knower poses a direct and formal challenge to the coherence of common notions of knowledge and truth. We've considered a number of ways one might try to meet that challenge: propositional views of truth and knowledge, redundancy or operator views, and appeal to hierarchy of various sorts. Mere appeal to propositions or operators, however, seems to be inadequate to the task of the Knower, at least if unsupplemented by an auxiliary recourse to (...) hierarchy. But the cost of hierarchy appears to be an abandonment of any notion of all truth or of omniscience. What the contradictions of the Knower seem to demand, then, is at least an abandonment of these. As noted in the introduction, the argument is complicated enough that one must be wary of dogmatic and precipitate conclusions. One may legitimately wonder whether some new response, or some variation on an old one, will yet offer a way out.Far too often, however, it is asked what has gone wrong with paradox rather than what paradox may have to teach us. What the Knower may have to teach us, I think, is that there really can be no coherent notion of all truth and really can be no coherent notion of omniscience. In its own way that conclusion is perhaps as humbling as is any traditional notion of God. (shrink)

This book discusses Thomistic commentary on the topics of physical premotion, grace, and the permission of sin, especially as these relate to the mysteries of predestination and reprobation. The author examines the fundamental tenets of the classical Thomistic account, and on this basis critiques the 20th century revisionist theories of Domingo Banez, Reginald Garrigou-Lagrange, Francisco Marin-Sola, Jacques Maritain, Bernard Lonergan, and Jean-Herve Nicolas. In conclusion, the implications of the traditional view are considered in light of the spiritual life.

As J. Baird Callicott has argued, Adam Smith's moral theory is a philosophical ancestor of recent work in environmental ethics. However, Smith's "all important emotion of sympathy" (Callicott, 2001, p. 209) seems incapable of extension to entities that lack emotions with which one can sympathize. Drawing on the distinctive account of sympathy developed in Smith's Theory of Moral Sentiments, as well as his account of anthropomorphizing nature in "History of Astronomy and Physics," I show that sympathy with non-sentient nature is (...) possible within a Smithian ethics. This provides the possibility of extending sympathy, and thereby benevolence and justice, to nature. (shrink)

How do conventions of communication emerge? How do sounds or gestures take on a semantic meaning, and how do pragmatic conventions emerge regarding the passing of adequate, reliable, and relevant information? My colleagues and I have attempted in earlier work to extend spatialized game theory to questions of semantics. Agent-based simulations indicate that simple signaling systems emerge fairly naturally on the basis of individual information maximization in environments of wandering food sources and predators. Simple signaling emerges by means of any (...) of various forms of updating on the behavior of immediate neighbors: imitation, localized genetic algorithms, and partial training in neural nets. Here the goal is to apply similar techniques to questions of pragmatics. The motivating idea is the same: the idea that important aspects of pragmatics, like important aspects of semantics, may fall out as a natural results of information maximization in informational networks. The attempt below is to simulate fundamental elements of the Gricean picture: in particular, to show within networks of very simple agents the emergence of behavior in accord with the Gricean maxims. What these simulations suggest is that important features of pragmatics, like important aspects of semantics, don't have to be added in a theory of informational networks. They come for free.

In a recent contribution to Learning for Democracy, Richard Bailey argues that Thomas Kuhn advocated an indoctrinatory model of science education, which is fundamentally authority-based. While agreeing with Bailey’s conclusion, this article suggests that Kuhn was attempting to solve an important problem which Bailey only touches on – how to ensure that science students do not become hypercritical. It continues by offering a critical rationalist solution to this problem, arguing that paradigms qua exemplars should be historical problem-solving episodes, rather than (...) model solutions to puzzles.

What is it for a sound or gesture to have a meaning, and how does it come to have one? In this paper, a range of simulations are used to extend the tradition of theories of meaning as use. The authors work throughout with large spatialized arrays of sessile individuals in an environment of wandering food sources and predators. Individuals gain points by feeding and lose points when they are hit by a predator and are not hiding. They can also (...) make sounds heard by immediate neighbours in the array, and can respond to sounds from immediate neighbours. No inherent meaning for these sounds is built into the simulation; under what circumstances they are sent, if any, and what the response to them is, if any, vary initially with the strategies randomized across the array. These sounds do take on a specific function for communities of individuals, however, with any of three forms of strategy change: direct imitation of strategies of successful neighbours, a localized genetic algorithm in which strategies are ‘crossed’ with those of successful neighbours, and neural net training on the behaviour of successful neighbours. Starting from an array randomized across a large number of strategies, and using any of these modes of strategy change, communities of ‘communicators’ emerge. Within these evolving communities the sounds heard from immediate neighbours, initially arbitrary across the array, come to be used for very specific communicative functions. ‘Communicators’ make a particular sound on feeding and respond to that same sound from neighbours by opening their mouths; they make a different sound when hit with a predator and respond to that sound by hiding. Robustly and persistently, even in simple computer models of communities of self-interested agents, something suggestively like signalling emerges and spreads. Keywords: meaning, communication, genetic algorithms, neural networks. (shrink)
