Our results provide clear evidence for Hey’s conjecture that recall negatively affects performance in sequential search. With experience, however, search behavior with and without recall converges toward the optimal reservation rule. We further find that (...) the utilization of optimal reservation rules is independent from the stochastic nature of the search cost. (shrink)

The paper reports experimental data on the behavior in the first-price sealed-bid auction for a varying number of bidders when values and bids are private information. This feedback-free design is proposed for the experimental test of the one-shot game situation. We consider both within-subjects and between-subjects variations. In line with the qualitative risk neutral Nash equilibrium prediction, the data show that bids increase in the number of bidders. However, in auctions involving a small number of bidders, average bids are above, (...) and in auctions involving a larger number of bidders, average bids are below the risk neutral equilibrium prediction. The quartile analysis reveals that bidding behavior is not constant across the full value range for a given number of bidders. On the high value quartiles, however, the average bid–value ratio is not different from the risk neutral prediction. The behavior is different when the winning bid is revealed after each repetition.

This highly readable theory of life and its origins offers a non-technical discussion of a chemical perspective on the fundamental organisation of living systems. Essays on the biological and philosophical significance of Ganti's work of thirty years indicate not only its enduring theoretical significance, but also the continuing relevance and heuristic power of Ganti's insights.

When this classic work was first published in 1976, its central tenet--more is not necessarily better--placed it in direct conflict with mainstream thought in economics. Within a few years, however, this apparently paradoxical claim was gaining wide acceptance. Scitovsky's ground-breaking book was the first to apply theories of behaviorist psychology to questions of consumer behavior and to do so in clear, non-technical language. Setting out to analyze the failures of our consumerist lifestyle, Scitovsky concluded that people's need for stimulation is (...) so vital that it can lead to violence if not satisfied by novelty--whether in challenging work, art, fashion, gadgets, late-model cars, or scandal. Though much of the book stands as a record of American post-war prosperity and its accompanying problems, the revised edition also takes into account recent social and economic changes. A new preface and a foreword by economist Robert Frank introduce some of the issues created by those changes and two revised chapters develop them, discussing among others the assimilation of counter-cultural ideas throughout American society, especially ideas concerning quality of life. Scitovsky draws fascinating connections between the new elite of college-educated consumers and the emergence of a growing underclass plagued by drugs and violence, perceptively tracing the reactions of these disparate groups to the problems of leisure and boredom. In the wake of the so-called "decade of greed" and amidst calls for a "kindler, gentler" society, The Joyless Economy seems more timely than ever. (shrink)

We investigate properties of accessible categories with directed colimits and their relationship with categories arising from ShelahʼsElementary Classes. We also investigate ranks of objects in accessible categories, and the effect of accessible functors on ranks.

This paper focuses on the dynamics of ethical perspectives that embody the Golden Rule of Morality. Based on critical analysis of this rule in various cultural and religious contexts, but also from the perspective of humanism, the author presents its paradoxical character, the essence of which is interpreted here in terms of a pointer to metaphysical reality. It turns out that social conditionality, as well as the self-referential concept as a starting point of any ethical reasoning, are serious epistemological challenges (...) for the application of the Golden Rule in the position of universal normativity that this study addresses. On the other hand, Judeo-Christian cosmology and the related basis for ethical foundations is presented here as an inspirational space of ethical reasoning in which the paradoxical character of the Golden Rule becomes rather an indicator of a deeper metaethical interpretation of one's own particular ethical attitudes and outcomes than a practical guide to the discovery of ethical universals.

Recent work in neurophilosophy has either made reference to the work of John Dewey or independently developed positions similar to it. I review these developments in order first to show that Dewey was indeed doing neurophilosophy well before the Churchlands and others, thereby preceding many other mid-twentieth century European philosophers’ views on cognition to whom many present day philosophers refer (e.g., Heidegger, Merleau-Ponty). I also show that Dewey’s work provides useful tools for evading or overcoming many issues in contemporary neurophilosophy (...) and philosophy of mind. In this introductory review, I distinguish between three waves among neurophilosophers that revolve around the import of evolution and the degree of brain-centrism. Throughout, I emphasize and elaborate upon Dewey’s dynamic view of mind and consciousness. I conclude by introducing the consciousness-as-cooking metaphor as an alternative to both the consciousness-as-digestion and consciousness-as-dancing metaphors. Neurophilosophical pragmatism—or neuropragmatism—recognizes the import of evolutionary and cognitive neurobiology for developing a science of mind and consciousness. However, as the cooking metaphor illustrates, a science of mind and consciousness cannot rely on the brain alone—just as explaining cooking entails more than understanding the gut—and therefore must establish continuity with cultural activities and their respective fields of inquiry. Neuropragmatism advances a new and promising perspective on how to reconcile the scientific and manifest images of humanity as well as how to reconstruct the relationship between science and the humanities.

The result of the author's extensive practical experience: a decade in computer process control using large scale systems, another decade in machine pattern-recognition for vision systems, and nearly a decade dealing with artificial intelligence and expert systems. These real-life projects have taught Vámos a critical appreciation of, and respect for, both abstract theory and the practical methodology that grows out of—and, in turn, shapes—those theories.Machine representation means a level of formalization that can be expressed by the instruments of mathematics, whereas (...) programming is not more and not less than a special linguistic translation of these mathematical formulae. How these all are related and controlled is a most practical philosophical and computation professional task. Wide experience in the practical fields of computer science, and the research of the underlying theoretical issues have led Vámos to the development of the attitude and activity of constructive skepticism.

How have broad patterns of violence and war changed from the dawn of humanity up to present time? In answering this question, researchers have typically framed their arguments and evidence in terms of the polarized debate between Hobbes (or hawks) and Rousseau (or doves). This article moves beyond the stalemated debate and integrates the most robust existing theoretical developments and empirical findings that have emerged from various disciplines over the past 20 years– primarily sociology, political science, anthropology, and archaeology– to (...) answer the question. Drawing on carefully curated violent lethality data for pre historically appropriate hunter-gatherers, as well as historical pre-state and state societies, it shows that simple narratives of violence and war decreasing through history from ostensibly high levels in the human state of nature, on the one hand, and the obverse insistence that the once mostly peaceful communities became highly belligerent with the transition to modernity, on the other, are both wrong. Instead, multiple lines of existing evidence and theoretical perspectives suggest a complex, non-linear, Kuznets-style relationship between violence and the passage of history. (shrink)

Spencer Dimmock has produced a convincing restatement, defence and update of Robert Brenner’s influential work on the origin of capitalism in England. The book productively engages with many Marxist and non-Marxist critics of the so-called ‘Brenner Thesis’, and presents fresh secondary and primary evidence in favour of it. This review sketches the theoretical background of Brenner’s intervention, summarises Dimmock’s take on Brenner, and comments on a few notable contemporary critiques of Brenner’s general framework which are not explicitly engaged with by (...) Dimmock. (shrink)

The philosophical problem of pictorial conversational implicatures can be summarized as follows: We have three propositions that are independently plausible and jointly inconsistent. -/- (Non-P) Anti-propositionalism: pictures do not have context-independent, conventionally encoded propositional content (propositional function). -/- (C) Only those representations can be used to convey conversational implicatures which have associated with them a context-independent, conventionally encoded propositional content (function). -/- (I) Pictures can be used to convey conversational implicatures. -/- There are three ways of responding to the problem: (...) affirm (Non-P) and (C) while denying (I); affirm (C) and (I) while denying (Non-P); or affirm (Non-P) and (I) while denying (C).

This paper contributes an analysis and formalisation of Damasio’s theory on core consciousness. Three important concepts in this theory are ‘emotion’, ‘feeling’ and ‘feeling a feeling’ . In particular, a simulation model is described of the dynamics of basic mechanisms leading via emotion and feeling to core consciousness, and dynamic properties are formally specified that hold for these dynamics at a more global level. These properties have been automatically checked for the simulation model. Moreover, a formal analysis is made of (...) relevant notions of representation used by Damasio. As part of this analysis, specifications of representation relations have been verified and confirmed against the simulation model. (shrink)

Sustainable development will shortly become the core issue of our everyday life. This article argues that only a nature-driven economy and society could give a final answer to sustainability questions.

Abstract: What follows is a contribution to the field of user modeling for adaptive teaching and learning programs especially in the medical field. The paper outlines existing approaches to the problem of extracting user information in a form that can be exploited by adaptive software. We focus initially on the so-called stereotyping method, which allocates users into classes adaptively, reflecting characteristics such as physical data, social background, and computer experience. The user classifications of the stereotyping method are however ad hoc (...) and unprincipled, and they can be exploited by the adaptive system only after a large number of trials by various kinds of users. We argue that the remedy is to create a database of user ontologies from which readymade taxonomies can be derived in such a way as to enable associated software to support a variety of different types of users.

Over the past three decades, cognitive science has been making a turn towards pragmatism. Here we outline steps towards completing this turn. As a handful of cognitive scientists and philosophers have been arguing more recently, the insights of William James, John Dewey, and George Herbert Mead are not only being re-discovered, they are also proving rather prescient in light of growing research. The new field of neuropragmatism aims to take these insights seriously and further into new directions for both pragmatism (...) and cognitive science. In this manifesto, a brief history of the relationship between classical pragmatism and the sciences of life and mind is offered as a background for twelve proposed theses of neuropragmatism. These theses serve as general guidelines for further philosophical and scientific research. To illustrate the possibilities and consequences of this neuropragmatic framework, neuropragmatist views on traditional questions of philosophy of mind, such as the mind-body relationship, are situated among other leading philosophical perspectives, like enactive, embodied, and embedded theories of cognition and mentation. Such views, however, when taken from a neuropragmatist perspecitve, have significant consequences for the philosophical project of reconciliation be- tween what Wilfrid Sellars called the scientific and manifest images of humanity. The difference in conceptions of experience and subesequently science are crucial for understanding the difference between Sellarsian neurophilosophy and neuropragmatism, as well as how to reach rapprochement between the sciences and the humanities.

Abstract The Joyless Economy focused on the boredom of the idle rich and neglected the boredom of the idle and idled poor. However, their boredom is much more serious than what the book dealt with, because it is chronic and often incurable. It usually begins with the neglect of destitute children who never learn how to concentrate on learning in school, become unruly and often end up unemployable, and have no better way than violence to release their energies.

Age of automation entails freedom from most of the common working roles. Signs are changes in employment, unemployment, professional structures, relevance of services, entertainment industry, working hours, and the nature of social relations. Warnings are suggested against voluntaristic interventions, neglect of social, historical relations. New approaches are required in the fields of lifelong education and in the education of socially disadvantaged people. The changes in evolutionary inherited motivations and life styles are critical challenges to mankind. Open society and lessons of (...) system control are recommended. (shrink)

Neuropragmatism offers a non-dualistic conception of experience from which scientific inquiries can provide resources for sociocultural critique. This reconstructive effort addresses what Emma Dowling calls the care crisis without succumbing to what Mike W. Martin calls therapeutic tyranny. This tyranny relies on problematic dualisms, between mind/body, mind/world, and fact/value, that are also found in neuropsychoanalysis. While pragmatism and psychoanalysis more generally share an evolutionary perspective and can overlap in therapeutic approaches, neuropsychoanalysis diverges from this effort in its dual-aspect monism and (...) positivistic conception of science. Where neuropsychoanalysis seeks to reconcile the first-person subjectivity of lived experience with the third-person objectivity of science, neuropragmatism offers reconstruction. In taking the neuropragmatic turn, neuropsychoanalysts can better utilize Freudian therapies in conjunction with active inference principles, such as the free-energy principle and allostasis. Along with neuropragmatism’s conception of experience as organism-environment dynamic engagement, neuropsychoanalysis can benefit from allostatic approaches to experience and inquiry without reducing experience to brute mechanism or denying the utility of such mechanisms for prediction and intervention. Understanding the value-ladenness of experience, primary and secondary, in everyday waking life and in reflective inquiry, empowers people to better care for themselves without succumbing to merely coping with neoliberal oppression.

Some consequences of direct realism and William James’s philosophy of mind are considered in terms of American naturalism as seen in the debate between John Dewey and Roy Wood Sellars. Sellars’s critical realism and evolutionary naturalism is compared and contrasted with Dewey’s pragmatic realism and emphatically evolutionary naturalism. Though these naturalisms are similar, there are significant differences between methodology, their critiques of James’s reflex arc concept in his Principles of Psychology, and the mind-body problem. Sellars’s critical realism and naturalism retains (...) a priori commitments to fixed categories and concepts, whereas Dewey’s emphatically evolutionary pragmatic naturalism is empirical and sees continuities where Sellars insists on discontinuities. One significant difference is Sellars’s maintaining a place for introspection as methodologically appropriate and Dewey’s’ rejection of it. These differences are illustrated through Sellars’s modification of the reflex arc to include an organic but interpretative step, and Dewey’s radical criticism of approaches like James’s and Sellars’s as recapitulating the Cartesian dualism that such views intended to overcome. These differences are finally contrasted in Sellars’s maintaining a privacy of mind by constraining it to the brain in a dual-aspect theory, while Dewey advocates mind as sociocultural, expanding mind into body and world.

I address the problem of caring for our body-mind through neuropragmatism, cybernetics, and Larry Hickman’s work on John Dewey and the philosophy of technology. The problems of body-mind health are related to Emma Dowling’s The Care Crisis. I address this crisis by drawing on Jay Schulkin’s conception of viability as the creative tension between stability and precarity. From this, I extend body-mind health to questions of democracy, leading to the proposal of body-mind-world as an elaboration of neuropragmatism’s evolutionary and ecological (...) conception of experience as Œ and Hickman’s distinction between the merely valued nature-as-nature and the valuable nature-as-culture. I conclude with a reimagination of creative democracy as a moral ideal for dealing with the care crisis. (shrink)

Cognitive science and its philosophy have been far too long consumed with representation. This concern is indicative of a creeping Cartesianism that many scientists and philosophers wish to evade. However, their naturalism is often insufficiently evolutionary to fully appreciate the lessons of pragmatism. If cognitive neuroscience and pragmatism are to be mutually beneficial, the representational-friendly scientists and the anti-representational pragmatists need an alternative to representation that still accounts for what many find so attractive about representation, namely intentionality. I propose that (...) instead of representations we philosophers and scientists begin thinking in terms of cultural affordances. Like Gibsonian affordances, cultural affordances are opportunities for action. However, unlike Gibsonian affordances, which are merely biological and available for immediate action in the immediately present environment, cultural affordances also present opportunities for thinking about the past and acting into the future—tasks typically attributed to representations.

This paper presents Michael Polanyi’s escape from Berlin to Manchester as part of a major wave of intellectual migration at the time of Hitler’s rise in Germany in 1933. Many émigré scientists and social scientists from Hungary experienced forced and unexpected relocation twice in the interwar era: first in 1919-20, after the fall of the Bolshevik-type Hungarian Republic of Councils, and again after the Nazi takeover. Once in exile, they formed an unusually tight support group assisting each other by cohorting, (...) networking, and bonding. Their group included a host of major refugee scientists, scholars, visual artists, musicians, men of letters, and public figures. The rich Hungarian contribution to German and, later, U.S. culture and civilization was, to a very great extent, the result of anti-Semitic policies and practices in Hungary after 1920 and in Germany after 1933.
