    En Memoria de Horacio Arló Costa.Gladys Palau & Diana I. Pérez - 2011 - Análisis Filosófico 31 (2):219-222.
    En este artículo me ocupo de la cuestión de cómo en las teorías de proceso dual se puede dar cuenta del autoengaño y su conexión con la racionalidad. Presento las versiones intencionalista y no intencionalista del autoengaño y muestro cómo el debate entre ellas puede dirimirse de manera más completa y satisfactoria en el marco de una teoría dual. En éste suelen aceptarse dos sistemas de razonamiento, uno heurístico y otro analítico, que compiten por el control de nuestras inferencias y (...)

    Rationality and Value: The Epistemological Role of Indeterminate and Agent-Dependent Values.Horacio Arló Costa - 2006 - Philosophical Studies 128 (1):7-48.
    An important trend in contemporary epistemology centers on elaborating an old idea of pragmatist pedigree: theory selection (and in general the process of changing view and fixing beliefs) presupposes epistemic values. This article focuses on analyzing the case where epistemic values are indeterminate or when the sources of valuation are multiple (epistemic values like coherence and simplicity need not order options in compatible ways). According to the theory that thus arises epistemic alternatives need not be fully ordered by an underlying (...)

  5. First-Order Classical Modal Logic.Horacio Arló-Costa & Eric Pacuit - 2006 - Studia Logica 84 (2):171 - 210.
    The paper focuses on extending to the first order case the semantical program for modalities first introduced by Dana Scott and Richard Montague. We focus on the study of neighborhood frames with constant domains and we offer in the first part of the paper a series of new completeness results for salient classical systems of first order modal logic. Among other results we show that it is possible to prove strong completeness results for normal systems without the Barcan Formula (like (...)

    Non-Adjunctive Inference and Classical Modalities.Horacio Arló Costa - 2005 - Journal of Philosophical Logic 34 (5/6):581 - 605.
    The article focuses on representing different forms of non-adjunctive inference as sub-Kripkean systems of classical modal logic, where the inference from □A and □B to □A ∧ B fails. In particular we prove a completeness result showing that the modal system that Schotch and Jennings derive from a form of non-adjunctive inference in (Schotch and Jennings, 1980) is a classical system strictly stronger than EMN and weaker than K (following the notation for classical modalities presented in Chellas, 1980). The unified (...)

    Belief Revision Conditionals: Basic Iterated Systems.Horacio Arló-Costa - 1999 - Annals of Pure and Applied Logic 96 (1-3):3-28.
    It is now well known that, on pain of triviality, the probability of a conditional cannot be identified with the corresponding conditional probability [25]. This surprising impossibility result has a qualitative counterpart. In fact, Peter Gärdenfors showed in [13] that believing ‘If A then B’ cannot be equated with the act of believing B on the supposition that A — as long as supposing obeys minimal Bayesian constraints. Recent work has shown that in spite of these negative results, the question (...)

  13. Ambiguity Aversion: The Explanatory Power of Indeterminate Probabilities.Horacio Arló-Costa & Jeffrey Helzner - 2010 - Synthese 172 (1):37-55.
    Daniel Ellsberg presented in Ellsberg (The Quarterly Journal of Economics 75:643–669, 1961) various examples questioning the thesis that decision making under uncertainty can be reduced to decision making under risk. These examples constitute one of the main challenges to the received view on the foundations of decision theory offered by Leonard Savage in Savage (1972). Craig Fox and Amos Tversky have, nevertheless, offered an indirect defense of Savage. They provided in Fox and Tversky (1995) an explanation of Ellsberg’s two-color problem (...)

    Fast and Frugal Heuristics: Rationality and the Limits of Naturalism.Horacio Arló-Costa & Arthur Paul Pedersen - 2013 - Synthese 190 (5):831-850.
    Gerd Gigerenzer and Thomas Sturm have recently proposed a modest form of what they describe as a normative, ecological and limited naturalism. The basic move in their argument is to infer that certain heuristics we tend to use should be used in the right ecological setting. To address this argument, we first consider the case of a concrete heuristic called Take the Best (TTB). There are at least two variants of the heuristic which we study by making explicit the choice (...)

  15. Contraction: On the Decision-Theoretical Origins of Minimal Change and Entrenchment.Horacio Arló-Costa & Isaac Levi - 2006 - Synthese 152 (1):129 - 154.
    We present a decision-theoretically motivated notion of contraction which, we claim, encodes the principles of minimal change and entrenchment. Contraction is seen as an operation whose goal is to minimize loses of informational value. The operation is also compatible with the principle that in contracting A one should preserve the sentences better entrenched than A (when the belief set contains A). Even when the principle of minimal change and the latter motivation for entrenchment figure prominently among the basic intuitions in (...)

  16. Social Norms, Rational Choice and Belief Change.Horacio Arlo-Costa & Arthur Paul Pedersen - unknown
    This article elaborates on foundational issues in the social sciences and their impact on the contemporary theory of belief revision. Recent work in the foundations of economics has focused on the role external social norms play in choice. Amartya Sen has argued in [Sen93] that the traditional rationalizability approach used in the theory of rational choice has serious problems accommodating the role of social norms. Sen's more recent work [Sen96, Sen97] proposes how one might represent social norms in the theory (...)

  17. Iterative Probability Kinematics.Horacio Arló-Costa & Richmond Thomason - 2001 - Journal of Philosophical Logic 30 (5):479-524.
    Following the pioneer work of Bruno De Finetti [12], conditional probability spaces (allowing for conditioning with events of measure zero) have been studied since (at least) the 1950's. Perhaps the most salient axiomatizations are Karl Popper's in [31], and Alfred Renyi's in [33]. Nonstandard probability spaces [34] are a well know alternative to this approach. Vann McGee proposed in [30] a result relating both approaches by showing that the standard values of infinitesimal probability functions are representable as Popper functions, and (...)

    Conditionals and Monotonic Belief Revisions: The Success Postulate.Horacio L. Arlo Costa - 1990 - Studia Logica 49 (4):557-566.
    One of the main applications of the logic of theory change is to the epistemic analysis of conditionals via the so-called Ramsey test. In the first part of the present note this test is studied in the “limiting case” where the theory being revised is inconsistent, and it is shown that this case manifests an intrinsic incompatibility between the Ramsey test and the AGM postulate of “success”. The paper then analyses the use of the postulate of success, and a weakening (...)

    First Order Extensions of Classical Systems of Modal Logic; the Role of the Barcan Schemas.Horacio Arló Costa - 2002 - Studia Logica 71 (1):87-118.
    The paper studies first order extensions of classical systems of modal logic (see (Chellas, 1980, part III)). We focus on the role of the Barcan formulas. It is shown that these formulas correspond to fundamental properties of neighborhood frames. The results have interesting applications in epistemic logic. In particular we suggest that the proposed models can be used in order to study monadic operators of probability (Kyburg, 1990) and likelihood (Halpern-Rabin, 1987).

    Knowing and Supposing in Games of Perfect Information.Horacio Arló-Costa & Cristina Bicchieri - 2007 - Studia Logica 86 (3):353 - 373.
    The paper provides a framework for representing belief-contravening hypotheses in games of perfect information. The resulting t-extended information structures are used to encode the notion that a player has the disposition to behave rationally at a node. We show that there are models where the condition of all players possessing this disposition at all nodes (under their control) is both a necessary and a sufficient for them to play the backward induction solution in centipede games. To obtain this result, we (...)

  26. Belief Revision Conditionals: Basic Iterated.Horacio Arlo-Costa - unknown
    Recent work has shown that in spite of these negative results, the question 'how to accept a conditional?' has a clear answer. Even if conditionals are not truth-carriers, they do have precise acceptability conditions. Nevertheless most epistemic models of conditionals do not provide acceptance conditions for iterated conditionals. One of the main goals of this essay is to provide a comprehensive account of the notion of epistemic conditionality covering all forms of iteration.

    Iterated Random Selection as Intermediate Between Risk and Uncertainty.Horacio Arlo-Costa & Jeffrey Helzner - unknown
    In (Hertwig et al. , 2003) Hertwig et al. draw a distinction between decisions from experience and decisions from description. In a decision from experience an agent does not have a summary description of the possible outcomes or their likelihoods. A career choice, deciding whether to back up a computer hard drive, cross a busy street, etc., are typical examples of decisions from experience. In such decisions agents can rely only of their encounters with the corresponding prospects. By contrast, an (...)

    Carlos Alchourrón, Peter Gärdenfors and David Makinson published in 1985 a seminal article on belief change in the Journal of Symbolic Logic. Researchers from various disciplines, from computer science to mathematical economics to philosophical logic, have continued the work first presented in this seminal paper during the last two decades. This paper explores some salient foundational trends that interpret the act of changing view as a decision. We will argue that some of these foundational trends are already present, although only (...)

    Comparative Ignorance and the Ellsberg Phenomenon.Horacio Arlo-Costa & Jeffrey Helzner - unknown
    The "Ellsberg phenomenon" has played a significant role in research on imprecise probabilities. Fox and Tversky [5] have attempted to explain this phenomenon in terms of their "comparative ignorance" hypothesis. We challenge that explanation and present empirical work suggesting an explanation that is much closer to Ellsberg's own diagnosis.

    Contextual Modals.Horacio Arlo-Costa & William Taysom - unknown
    In a series of recent articles Angelika Kratzer has argued that the standard account of modality along Kripkean lines is inadequate in order to represent context-dependent modals. In particular she argues that the standard account is unable to deliver a non-trivial account of modality capable of overcoming inconsistencies of the underlying conversational background.

    Desire-as-Belief Implies Opinionation or Indifference.Horacio Costa, John Collins & Isaac Levi - 1995 - Analysis 55 (1):2-5.
    The anti- Humean proposal of constructing desire as belief about what would be good must be abandoned on pain of triviality. Our central result shows that if an agent's belief- desire state is represented by Jeffrey's expected value theory enriched with the Desire as Belief Thesis (DAB), then, provided that three pairwise inconsistent propositions receive non- zero probability, the agent must view with indifference any proposition whose probability is greater than zero. Unlike previous results against DAB our Opinionation or Indifference (...)

They provided a completeness result for the simplest version of contraction that they call Levi-contraction but left open the problem of characterizing axiomatically the more complex operation of value-based contraction or saturatable contraction. In this paper we propose an axiomatization for this operation and prove a completeness result for it. We argue that the (...)

    Models of Preference Reversals and Personal Rules: Do They Require Maximizing a Utility Function with a Specific Structure?Horacio Arló-Costa - 2005 - Behavioral and Brain Sciences 28 (5):650-651.
    One of the reasons for adopting hyperbolic discounting is to explain preference reversals. Another is that this value structure suggests an elegant theory of the will. I examine the capacity of the theory to solve Newcomb's problem. In addition, I compare Ainslie's account with other procedural theories of choice that seem at least equally capable of accommodating reversals of preference.

    Similarity in Logical Reasoning and Decision-Making.Horacio Arló-Costa - 2005 - Behavioral and Brain Sciences 28 (1):14-15.
    Normative accounts in terms of similarity can be deployed in order to provide semantics for systems of context-free default rules and other sophisticated conditionals. In contrast, procedural accounts of decision in terms of similarity (Rubinstein 1997) are hard to reconcile with the normative rules of rationality used in decision-making, even when suitably weakened.

    Hypothetical Revision and Matter-of-Fact Supposition.Horacio Arló Costa - 2001 - Journal of Applied Non-Classical Logics 11 (1-2):203-229.
    The recent literature offers several models of the notion of matter of fact supposition1 revealed in the acceptance of the so-called indicative conditionals. Some of those models are qualitative [Collins 90], [Levi 96], [Stalnaker 84]. Other probabilistic models appeal either to infinitesimal probability or two place probability functions. Recent work has made possible to understand which is the exact qualitative counterpart of the latter probabilistic models. In this article we show that the qualitative notion of change that thus arises is (...)
