    Why Are Three-Dimensional Organisms Composed of Two-Dimensional Layers?Yair Neuman & Itzhak Orion - 2007 - Foundations of Science 12 (1):1-7.
    Multicellular organisms are ensembles of quasi-two-dimensional structures (sheets) of various kinds. Why should the development of all organisms be mediated by a quasi-two-dimensional structure? Why does such development avoid a direct confrontation with the third dimension? In this paper, we accept the challenge of addressing this question from the perspective of computational geometry and suggest that the construction of three-dimensional organisms may be explained by the constraints imposed on a bottom-up construction process.

    Rational Choice.Itzhak Gilboa - 2012 - MIT Press.
    This book offers a rigorous, concise, and nontechnical introduction to some of the fundamental insights of rational choice theory. It draws on formal theories of microeconomics, decision making, games, and social choice, and on ideas developed in philosophy, psychology, and sociology. Itzhak Gilboa argues that economic theory has provided a set of powerful models and broad insights that have changed the way we think about everyday life. He focuses on basic insights of the rational choice paradigm--the general conceptualization rather (...)

    A Theory of Case-Based Decisions.Itzhak Gilboa & David Schmeidler - 2001 - Cambridge University Press.
    Gilboa and Schmeidler provide a paradigm for modelling decision making under uncertainty. Unlike the classical theory of expected utility maximization, case-based decision theory does not assume that decision makers know the possible 'states of the world' or the outcomes, let alone the decision matrix attaching outcomes to act-state pairs. Case-based decision theory suggests that people make decisions by analogies to past cases: they tend to choose acts that performed well in the past in similar situations, and to avoid acts that (...)

    Stalking the Wild Pendulum: On the Mechanics of Consciousness.Itzhak Bentov - 1977 - Distributed to the Book Trade in the U.S. By Harper and Row.
    In his exciting and original view of the universe, Itzhak Bentov has provided a new perspective on human consciousness and its limitless possibilities. Widely known and loved for his delightful humor and imagination, Bentov explains the familiar world of phenomena with perceptions that are as lucid as they are thrilling. He gives us a provocative picture of ourselves in an expanded, conscious, holistic universe. _.

    Rationality of Belief Or: Why Savage’s Axioms Are Neither Necessary nor Sufficient for Rationality.Itzhak Gilboa, Andrew Postlewaite & David Schmeidler - 2012 - Synthese 187 (1):11-31.
    Economic theory reduces the concept of rationality to internal consistency. As far as beliefs are concerned, rationality is equated with having a prior belief over a “Grand State Space”, describing all possible sources of uncertainties. We argue that this notion is too weak in some senses and too strong in others. It is too weak because it does not distinguish between rational and irrational beliefs. Relatedly, the Bayesian approach, when applied to the Grand State Space, is inherently incapable of describing (...)

    Orion's Club. A Note on Germanicus, Arati Phaenomena 651.Emanuele Berti - 2019 - Classical Quarterly 69 (2):916-917.
    In lines 646–60 of his translation of Aratus’ Phaenomena, Germanicus narrates the story of Orion, the mythical hunter killed by a scorpion sent by Diana because of his attempt to rape the goddess, and then transformed into a star. In particular, line 651 describes Orion's hunting:nudabatque feris angusto stipite siluas.

    Is It Always Rational to Satisfy Savage's Axioms?Itzhak Gilboa, Andrew Postlewaite & David Schmeidler - 2009 - Economics and Philosophy 25 (3):285-296.
    This note argues that, under some circumstances, it is more rational not to behave in accordance with a Bayesian prior than to do so. The starting point is that in the absence of information, choosing a prior is arbitrary. If the prior is to have meaningful implications, it is more rational to admit that one does not have sufficient information to generate a prior than to pretend that one does. This suggests a view of rationality that requires a compromise between (...)

    What Are Axiomatizations Good For?Itzhak Gilboa, Andrew Postlewaite, Larry Samuelson & David Schmeidler - 2019 - Theory and Decision 86 (3-4):339-359.
    Do axiomatic derivations advance positive economics? If economists are interested in predicting how people behave, without a pretense to change individual decision making, how can they benefit from representation theorems, which are no more than equivalence results? We address these questions. We propose several ways in which representation results can be useful and discuss their implications for axiomatic decision theory.

    We suggest a model that describes how counterfactuals are constructed and justified. The model can describe how counterfactual beliefs are updated given the unfolding of actual history. It also allows us to examine the use of counterfactuals in prediction, and to show that a logically omniscient reasoner gains nothing from using counterfactuals for prediction.

    Emotion, Utility Maximization, and Ecological Rationality.Yakir Levin & Itzhak Aharon - 2014 - Mind and Society 13 (2):227-245.
    This paper examines the adequacy of an evolutionary-oriented notion of rationality—ecological rationality—that has recently been proposed in economics. Ecological rationality is concerned with what it is rational to do, and in this sense is a version of what philosophers call ‘practical rationality’. Indeed, the question of the adequacy of ecological rationality as it is understood in the paper, is the question of whether ecological rationality is a genuine notion of practical rationality. The paper first explicates and motivates the notion of (...)

    Rationality and the Bayesian Paradigm.Itzhak Gilboa - 2015 - Journal of Economic Methodology 22 (3):312-334.
    It is argued that, contrary to a rather prevalent view within economic theory, rationality does not imply Bayesianism. The note begins by defining these terms and justifying the choice of these definitions, proceeds to survey the main justification for this prevalent view, and concludes by highlighting its weaknesses.

    Peirescs Nebel im Sternbild Orion—eine neue Textgrundlage für die Geschichte von M42.Harald Siebert - 2009 - Annals of Science 66 (2):231-246.
    Nicolas Claude Fabri de Peiresc gilt als Entdecker des Orion-Nebels . Als solcher ist er seit neunzig Jahren bekannt. Der französische Astronom und Wissenschaftshistoriker Guillaume Bigourdan zog diesen Schluss aus Aufzeichnungen, die er in Peirescs unveröffentlichtem Journal des observations entdeckt und 1916 veröffentlicht hatte. Demnach soll Peiresc den Orion-Nebel im November 1610 beobachtet haben. Peirescs Zeitgenossen jedoch war diese Beobachtung verborgen geblieben, und niemandem sonst gelang sie so früh nach Einführung des Teleskops. Mittlerweile sind Zweifel an Peirescs Entdeckung (...)

  32. Making Statements and Approval Voting.Enriqueta Aragones, Itzhak Gilboa & Andrew Weiss - 2011 - Theory and Decision 71 (4):461-472.
    We assume that people have a need to make statements, and construct a model in which this need is the sole determinant of voting behavior. In this model, an individual selects a ballot that makes as close a statement as possible to her ideal point, where abstaining from voting is a possible (null) statement. We show that in such a model, a political system that adopts approval voting may be expected to enjoy a significantly higher rate of participation in elections (...)

  33. On the Definition of Objective Probabilities by Empirical Similarity.Itzhak Gilboa, Offer Lieberman & David Schmeidler - 2010 - Synthese 172 (1):79 - 95.
    We suggest to define objective probabilities by similarity-weighted empirical frequencies, where more similar cases get a higher weight in the computation of frequencies. This formula is justified intuitively and axiomatically, but raises the question, which similarity function should be used? We propose to estimate the similarity function from the data, and thus obtain objective probabilities. We compare this definition to others, and attempt to delineate the scope of situations in which objective probabilities can be used.

    A simulação da morte: versão e aversão em Montaigne.Eduino José Orione - 2012 - Kriterion: Journal of Philosophy 53 (126):609-611.
    Montaigne, no "De l'art de conferer", discute critérios que permitem distinguir os homens segundo suas capacidades (suffisances). A "maneira" de discursar ocupa o centro desta questão e entre suas qualidades se destaca a "ordem", que nos é apresentada, sobretudo, a partir dos desvios da "tolice" (sottise) e "obstinação" (opiniastreté), símbolos do dogmatismo e de uma errônea lide com os saberes que se apoiam na memória. Procura-se mostrar que a ordem se funda na assimilação e penetração do julgamento nas matérias que (...)

    Changes in Work Centrality and Other Life Areas in Israel: A Longitudinal Study.Moshe Sharabi & Itzhak Harpaz - 2007 - Journal of Human Values 13 (2):95-106.
    This unique longitudinal study examines the state of work centrality and other life areas in Israel among the same individuals over a 12-year period. A new representative sample of the Israeli labour force in 1992–93 assists us in exploring whether the changes occurred by cohort, life course or period effect. The restudied sample maturation led to a decrease in the importance of leisure, while the importance of work, family, community and religion remained stable. The increase of work centrality between the (...)

    Subjective Distributions.Itzhak Gilboa & David Schmeidler - 2004 - Theory and Decision 56 (4):345-357.
    A decision maker has to choose one of several random variables whose distributions are not known. As a Bayesian, she behaves as if she knew the distributions. In this paper we suggest an axiomatic derivation of these (subjective) distributions, which is more economical than the derivations by de Finetti or Savage. Whereas the latter derive the whole joint distribution of all the available random variables, our approach derives only the marginal distributions. Correspondingly, the preference questionnaire needed in our case is (...)

  45. History as a Coordination Device.Rossella Argenziano & Itzhak Gilboa - 2012 - Theory and Decision 73 (4):501-512.
    Coordination games often have multiple equilibria. The selection of equilibrium raises the question of belief formation: how do players generate beliefs about the behavior of other players? This article takes the view that the answer lies in history, that is, in the outcomes of similar coordination games played in the past, possibly by other players. We analyze a simple model in which a large population plays a game that exhibits strategic complementarities. We assume a dynamic process that faces different populations (...)

    This note documents Aumann's reason for omitting the “empty shells” argument for the common prior assumption from the final version of “Correlated Equilibrium as an Expression of Bayesian Rationality.” It then continues to discuss the argument and concludes that rational entities cannot learn their own identity; if they do not know it a priori, they never will.
