The focus of the article is scientific rationality. Drawing from the historical development of science, the author identifies three main types of scientific rationality: classical rationality, nonclassical rationality, and post-nonclassical rationality. They are distinguished based on such criteria as 1) features of systematic organization of the objects studied by science; 2) the system of ideals and norms used in research; 3) different types of philosophical-methodological reflection on cognitive activity. The essay discusses each of (...) the three identified types providing a thorough analysis of their main features and characteristics. (shrink)

Modes of rationality in nursing documentation: biology, biography, and the ‘voice of nursing’ This article is based on a discourse analysis of the complete nursing records of 45 patients, and concerns the modes of rationality that mediated text‐based accounts relating to patient care that nurses recorded. The analysis draws on the work of the critical theorist, Jürgen Habermas, who conceptualised rationality in the context of modernity according to two types: purposive rationality based on an instrumental (...) logic, and value rationality based on ethical considerations and moral reasoning. Our analysis revealed that purposive rationality dominated the content of nursing documentation, as evidenced by a particularly bio‐centric and modernist construction of the workings of the body within the texts. There was little reference in the documentation to central themes of contemporary nursing discourses, such as notions of partnership, autonomy, and self‐determination, which are associated with value rationality. Drawing on Habermas, we argue that this nursing documentation depicted the colonisation of the sociocultural lifeworld by the bio‐technocratic system. Where nurses recorded disagreements that patients had with medical regimes, the central struggle inherent in the project of modernity became transparent — the tension between the rational and instrumental control of people through scientific regulation and the autonomy of the subject. The article concludes by problematising communicative action within the context of nursing practice. (shrink)

Based on a framework that distinguishes several types, roles and functions of values in science, we discuss legitimate applications of values in the validation of computer simulations. We argue that, first, epistemic values, such as empirical accuracy and coherence with background knowledge, have the role to assess the credibility of simulation results, whereas, second, cognitive values, such as comprehensiveness of a conceptual model or easy handling of a numerical model, have the role to assess the usefulness of a model (...) for investigating a hypothesis. In both roles, values perform what we call first-order functions. In addition, cogni¬tive values may also serve an auxiliary function by facilitating the assessment of credibility. As for a third type of values, i.e. social values, their legitimate role consists in specifying and weighing epistemic and cognitive values with respect to practical uses of a simulation, which is considered a second-order function. Rational intersubjective agreement on how to specify and weigh the different values is supposed to ensure objectivity in simulation validation. (shrink)

We present evidence from a pre-registered experiment indicating that a philosophical argument––a type of rational appeal––can persuade people to make charitable donations. The rational appeal we used follows Singer’s well-known “shallow pond” argument (1972), while incorporating an evolutionary debunking argument (Paxton, Ungar, & Greene 2012) against favoring nearby victims over distant ones. The effectiveness of this rational appeal did not differ significantly from that of a well-tested emotional appeal involving an image of a single child in need (Small, Loewenstein, and (...) Slovic 2007). This is a surprising result, given evidence that emotions are the primary drivers of moral action, a view that has been very influential in the work of development organizations. We did not find support for our pre-registered hypothesis that combining our rational and emotional appeals would have a significantly stronger effect than either appeal in isolation. However, our finding that both kinds of appeal can increase charitable donations is cause for optimism, especially concerning the potential efficacy of well-designed rational appeals. We consider the significance of these findings for moral psychology, ethics, and the work of organizations aiming to alleviate severe poverty. (shrink)

According to the received view in metaethics, a Neo-Humean theory of rationality entails that there cannot be any objective moral reasons, i.e. moral reasons that are independent of actual desires. In this paper, I argue that there is a version of this theory that is compatible with the existence of objective moral reasons. The key is to distinguish between (i) the process of rational deliberation that starts off in an agent's actual desires, and (ii) the rational principle that an (...) agent employs in such a process. I maintain that it is the latter which explains why it is rational for an agent to have a certain desire, not the former. As a result, there might be two types of principles. The second type of principle leaves room for objective moral reasons. (shrink)

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I (...) argue that this under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)

Contemporary economic theory is generally regarded as a scientific or at least potentially so. The replacing of the cardinal theory of utility measurement by the ordinal theory was supposed to prepare the groundwork for economics as a genuine science. But in adopting the ordinal approach, theorists saw fit to anchor ordinal theory to axioms of choice founded on principles of rational behavior. Behavior according to these axioms was embodied in the ideal type model of rational economic man. This model served (...) the basis for scientific explanation of the choices made by actual economic agents. I argue though that the postulate of rationality is a normative principle and that this compromises the scientific pretensions of economic theory. Yet the theorist must rely on this principle to formulate predictive and explanatory theories. This raises questions as to whether it is possible that economic theory satisfy the same kind of scientific criteria set down for research in the natural sciences. (shrink)

In his disputatio, Johann Peter von Ludewig provides a history of rational philosophy among the Arabs and sets out to contextualize the Turks’ attitude to it. Like many Lutheran scholars of the time, Ludewig believed that Islam, as a religion, impeded the development of rational philosophy in the Arab world. However, unlike those philosophers, he examines external influences that may have fed the interest of Arab Muslims in rational philosophy, especially dialectic. Unlike Orthodox Lutherans, such as Pfeiffer and Kromayer, in (...) his conclusion, Ludewig prays that Muslim philosophers cultivate reason to overcome the "deceit of Muhammadanists" toward rational worship. The use of the contentious and seemingly oxymoronic phrase “rational worship” (logikē latreia: λογική λατρεία, from Rom. 12:1), combining “rationality” and “worship” together refects, to a certain extent, the Enlightenment belief that reason could be used to understand the nature of God against any type of irrational religiosity. The idea of worshipping God rationally and equating God with reason shows the intellectual engagement of Protestant scholars with Enlightenment rationalism. (shrink)

Debunking arguments are arguments that seek to undermine a belief or doctrine by exposing its causal origins. Two prominent proponents of such arguments are the utilitarians Joshua Greene and Peter Singer. They draw on evidence from moral psychology, neuroscience, and evolutionary theory in an effort to show that there is something wrong with how deontological judgments are typically formed and with where our deontological intuitions come from. They offer debunking explanations of our emotion-driven deontological intuitions and dismiss complex deontological theories (...) as products of confabulatory post hoc rationalization. Through my discussion of Greene and Singer’s empirically informed debunking of deontology, I introduce the distinction between two different types of debunking arguments. The first type of debunking argument operates through regular undercutting defeat, whereas the second type relies on higher-order evidence. I argue that the latter type of debunking argument, of which the argument from confabulation is an example, is objectionably sloppy and therefore inadmissible in academic discussion. (shrink)

John Broome has developed an account of rationality and reasoning which gives philosophical foundations for choice theory and the psychology of rational agents. We formalize his account into a model that differs from ordinary choice-theoretic models through focusing on psychology and the reasoning process. Within that model, we ask Broome’s central question of whether reasoning can make us more rational: whether it allows us to acquire transitive preferences, consistent beliefs, non-akratic intentions, and so on. We identify three structural (...) class='Hi'>types of rationality requirements: consistency requirements, completeness requirements, and closedness requirements. Many standard rationality requirements fall under this typology. Based on three theorems, we argue that reasoning is successful in achieving closedness requirements, but not in achieving consistency or completeness requirements. We assess how far our negative results reveal gaps in Broome's theory, or deficiencies in choice theory and behavioral economics. (shrink)

What, normatively speaking, are the grounds of rational choice? This paper defends ‘comparativism’, the view that a comparative fact grounds rational choice. It examines three of the most serious challenges to comparativism: 1) that sometimes what grounds rational choice is an exclusionary-type relation among alternatives; 2) that an absolute fact such as that it’s your duty or conforms to the Categorial Imperative grounds rational choice; and 3) that rational choice between incomparables is possible, and in particular, all that is needed (...) for the possibility of rational choice is that one alternative is not worse than the others. Each challenge is questioned. If comparativism is correct, then no matter what normative theory you favor, your answer to the question, ‘What makes my choice rational?’ must be comparative in form. In this way, comparativism provides a framework for normative theorizing. (shrink)

According to Bayesian epistemology, rational learning from experience is consistent learning, that is learning should incorporate new information consistently into one's old system of beliefs. Simon M. Huttegger argues that this core idea can be transferred to situations where the learner's informational inputs are much more limited than Bayesianism assumes, thereby significantly expanding the reach of a Bayesian type of epistemology. What results from this is a unified account of probabilistic learning in the tradition of Richard Jeffrey's 'radical probabilism'. Along (...) the way, Huttegger addresses a number of debates in epistemology and the philosophy of science, including the status of prior probabilities, whether Bayes' rule is the only legitimate form of learning from experience, and whether rational agents can have sustained disagreements. His book will be of interest to students and scholars of epistemology, of game and decision theory, and of cognitive, economic, and computer sciences. (shrink)

The article covers such issues as the relevance of the theory of perception as a multi-level information processing, the methodological role of the concept of representation and the relation of neurodynamic structures to subjective experience. The author critically reviews the philosophical presumptions underlying the various concepts of “local rationality,” the core of which is constituted by the belief that large ethnic cultures generate or are based on their own rationality and their own logic. Three statements are successively considered: (...) thinking is based on the inherent rules of rationality, logic is an extract of rationality, and types of rationality are geographically consistent with large ethnocultural communities. Empirical arguments are presented that demonstrate equivocality of the first two theses. In particular, firstly, it is shown that the genuine rationality of thinking lies not in following the rules that are immanent to it, but in the development of thinking and, more broadly, cognitive operations towards optimization of certain indicators of the cognitive or motor system that are important for survival and adaptation. In addition, this rationality is multivariate, and the choice between variants is often weakly determined or even random. Thus, the first statement turns out to be refuted. Secondly, by reference to the well-known experiments, it is shown that most people do not explicitly follow some declared logical rules in solving even logical or mathematical problems, and yet there is reason to consider their behavior rational. The third thesis, as shown with some limited empirical material, appears to be partially confirmed. Nevertheless, the demonstration of the doubtfulness of the first two theses makes the conclusion that different nations have different logics insufficiently substantiated. (shrink)

I will begin by considering how the social world appears to the scientific observer and ask the question of whether the world of scientific research, with all its categories of meaning interpretation and with all its conceptual schemes of action, is identical with the world in which the observed actor acts. Anticipating the result, I may state immediately that with the shift from one level to the other, all the conceptual schemes and all the terms of interpretation must be modified.Proceeding (...) in this direction, I encounter several problems overlapping with the problem of rational action and the “rational act unit” in Professor ParsonsParsons, Talcott’ sense. First: The conceptual scheme of rational action presupposes a more or less definite knowledge of, or orientation within, the world in which this action is performed. In this sense the term, “rationality”, is not specific to the conceptual scheme of action; it embraces the conceptual scheme of the world in general and is only one element in it. Therefore, we also must examine the problem of orientation in this world. Second: We ought to keep in mind that all interpretation of the social world has to start from the actor’s subjective point of view. Therefore, we cannot accept the term, “unit act”, as such, without trying to reduce it to its subjective meaning. Here I have to discuss in general terms why I insist on the subjective point of view. This is more than the whim of a few social scientists; social science cannot be built up except by taking cognizance of the subjective meaning the actor connects with his acting. Finally, I have to discuss the fact that there are social sciences operating on high theoretical levels that, like economics, apparently prefer to deal with statistical curves and mathematical formulae rather than with actions of human beings in the social world, yet they use the term, “rational action”, as an indispensable element of their systems. I will have to show what modification this term undergoes in these types of social sciences..). (shrink)

In, it was argued that Professor David Kaplan's model of S-explanation could be formulated so as to provide a unified framework for three types of explanation, viz., potential, rationally acceptable, and true. In this note I correct an error in the statement of the conditions for a potential direct S-explanans, show that the corrected version leads to a further simplification in the conditions of the model, and propose a fourth type of explanation which the framework of S-explanation can accommodate.

I provide an account of the cognitive attitude of trust that explains the role trust plays in the planning of rational agents. Many authors have dismissed choosing to trust as either impossible or irrational; however, this fails to account for the role of trust in practical reasoning. A can have therapeutic, coping, or corrective reasons to trust B to ${\phi}$ , even in the absence of evidence that B will ${\phi}$ . One can choose to engage in therapeutic trust to (...) inspire trustworthiness, coping trust to simplify one’s planning, or corrective trust to avoid doing a testimonial injustice. To accommodate such types of trust, without accepting doxastic voluntarism, requires an account of the cognitive attitude of trust broader than belief alone. I argue that trust involves taking the proposition that someone will do something as a premise in one’s practical reasoning, which can be a matter of believing or accepting the proposition. I defend this account against objections that it (i) provides insufficient rational constraints on trust, (ii) conflates trust and pretense of trust, and (iii) cannot account for the rationality of back-up planning.

We want to consider anew the question, which is recurrent along the history of philosophy, of the relationship between rationality and mathematics, by inquiring to which extent the structuration of rationality, which ensures the unity of its function under a variety of forms (and even according to an evolution of these forms), could be considered as homeomorphic with that of mathematical thought, taken in its movement and made concrete in its theories. This idea, which is as old as (...) philosophy itself, although it has not been dominant, has still been present to some degree in the thought of modern science, in Descartes as well as in Kant, Poincaré or Einstein (and a few other scientists and philosophers). It has been often harshly questioned, notably in the contemporaneous period, due to the failure of the logistic programme, as well as to the variety of “empirical” knowledges, and, in a general way, to the character of knowledges that show them as transitory, evolutive and mind-built. However, the analysis of scientific thought through its inventive and creative processes leads to characterize this thought as a type of rational form whose configurations can be detailed rather precisely. In this work we shall propose, first, a quick sketch of some philosophical requirements for such a research programme, among which the need for an harmonization, and even a conciliation, between the notions of rational (or rationality), of intuitive grasp and of creative thought. Then we shall examine some processes of creative scientific thought bearing on the knowledge and the understanding of the world, distinct from mathematics although keeping tight relations with them. Contemporary physical theories are privileged witnesses in this respect, for in them the rational thought of phenomena makes an intrinsic use of mathematical thought, which contributes to the structuration of the formers and to the expression of their concepts (which entails the physical contents of the latter). The General Theory of Relativity and the Quantum Theory are exemplar to this, as they directly reveal what can be called the “drag of physical thought par the mathematical form”, which makes possible to overcome the limitations of the physical knowledge previously adquired. This process is tightly related to the modalities and to the stucture of the rational thought underlying it. This is what we would like to show. DOI:10.5007/1808-1711.2011v15n2p303. (shrink)

The article touches upon the problem of concept “Indian tradition of rationality”. The author recalls a genetic link of the concept with Western philosophy. She notices the complexity of its application to Indian material, gives some examples in which the use of Western concepts of “reason”, “methods of cognition”, etc., leads to a distortion of the text’s meaning, and when an application of the criteria of Western logic to analysis of Indian philosophical discourse gives the readers an impression of (...) its absurdity. However, according to the author’s mind, the difficulties with the applying of Western concepts are not the sufficient grounds to abandon them. This conclusion follows from the presence of comparative studies by researchers belonging to both traditions, who compare successfully Western and Indian kinds of logico-epistemological type of rationality. The difficulties just bring up the questions about new instrumental concepts and methods of comparative studies more adequate to Indian culture. There are two possible directions for the studies of Indian tradition of rationality in connection with the revision of contents of the concepts in Western post- modern philosophy. In the first of them the concept of rationality can not to be used at all, then the phenomenology of practices of Indian discourse becomes the subject of research, i.e. the discourse images in different contexts, its explicit and implicit foundations and aims, which aren’t coincide with Western ones. In the second case Indian rationality can be analyzed in accordance with the criteria of transversal reason and transversal rationality. (shrink)

In this paper, I address two connected issues that arise when one considers a rational agent facing a decision problem. One is whether or not the agent may find that the dictates of rationality are such that they cannot all be followed. For example, one may ask whether or not the requirements on the agent's actions imposed by rationality can conflict in an irreconcilable way, making it impossible to satisfy all of them. Put differently, one may ask whether (...) or not any apparent conflict of this type must in fact be capable of rational resolution. I shall say that an agent who is in a position in which the requirements of rationality cannot all be satisfied faces a feasibility dilemma, and I shall characterize certain conceptions of rationality that differ according to whether or not they admit such a possibility. A second issue concerns the number of options that may be deemed rational in a decision problem. Is rationality sufficiently determinate that it always dictates precisely one choice, or may there be more than one rationally permissible option? Is there anything about rationality itself that guarantees that any of the possible options could rationally be chosen? I shall call this issue – whether the concept of rationality itself places any limits on the number of options that may be deemed rational in a given problem – the numbers problem. (shrink)

In finite type arithmetic, the real numbers are represented by rapidly converging Cauchy sequences of rational numbers. Ulrich Kohlenbach introduced abstract types for certain structures such as metric spaces, normed spaces, Hilbert spaces, etc. With these types, the elements of the spaces are given directly, not through the mediation of a representation. However, these abstract spaces presuppose the real numbers. In this paper, we show how to set up an abstract type for the real numbers. The appropriateness of (...) our construction works in tandem with the bounded functional interpretation. (shrink)

When new technologies create risks, government agencies use regulations to control the risks. This paper advances a method of evaluating a democracy’s regulation of risks. It assumes that a regulatory agency should act as the public would act in ideal conditions for negotiation if the public were rational and informed. The method relies on decision theory and game theory to ascertain whether a regulation has the public’s informed support. The Occupational Safety and Health Administration’s regulation of exposure to carcinogens in (...) the workplace illustrates the account of regulation. The illustration draws attention to a distinction between physical and information-sensitive risks. Regulations guided by the physical sciences alone may overlook the value of reducing information-sensitive risks. These risks exist objectively, and rational people generally have an aversion to them. An information-sensitive risk and an aversion to it may persist after acquisition of all available relevant information. Democratic regulation justifiably aims to reduce such risks. (shrink)

This essay some first steps toward the naturalization of what I call rational intentionality or alternatively type II intentionality. By rational or type II intentionality, I mean that full combination of rational powers and content-bearing states that is paradigmatically enjoyed by mature intact human beings. The problem I set myself is to determine the extent to which the only currently extant approach to the naturalization of the intentional that has the singular virtue of not being a non-starter can be aggregated (...) up into an account of rational intentionality. I have in mind a broadly defined family of accounts whose main members are the indicator/information-theoretic approach of Dretske (1988), the asymmetric dependence theory of Jerry Fodor (1987, 1990, 1994) and the teleo-semantics of Ruth Millikan (1984, 1993). Somewhat inaccurately, I will call this family of approaches the information-theoretic family. To be sure, there is only a rough family resemblance among the members of the information-theoretic family. Indeed, several intense quarrels divide the members of that family one from another, but the precise outcome of those internecine struggles is not directly relevant to the aims of this essay. ² Taken collectively, the information-theoretic family yields a compelling picture of the place of at least a crude form of intentionality -- what I call frog-like or type I intentionality -- in the natural order. Though frog-like or type I intentionality is, I think, a genuine species of intentionality, it may subsist in the absence of rational powers. It is that species of intentionality enjoyed by irritable creatures who, following Brandom (1994). (shrink)

Students systematically and deliberately apply rule‐based but erroneous algorithms to solving unfamiliar arithmetic problems. These algorithms result in erroneous solutions termed rational errors. Computationally, students' erroneous algorithms can be represented by perturbations or bugs in otherwise correct arithmetic algorithms (Brown & VanLehn, 1980; Langley & Ohilson, 1984; VanLehn, 1983, 1986, 1990; Young S O'Sheo, 1981). Bugs are useful for describing how rational errors occur but bugs are not sufficient for explaining their origin. A possible explanation for this is that rational (...) errors are the result of incorrect induction from examples. This prediction is termed the “induction hypothesis” (VanLehn, 1986). The purpose of the present study was to: (a) expand on post formulations of the induction hypothesis, and (b) use a new methodology to test the induction hypothesis more carefully than has been done previously. The first step involved teaching participants a new number system called NewAbacus, a written modification of the abacus system. The second step consisted of dividing them into different groups, where each individual received an example of only one port of the NewAbacus addition algorithm. During the third and final step, participants were instructed to solve both familiar and unfamiliar types of addition problems in NewAbacus. The induction hypothesis was supported by using both empirical and computational investigations. (shrink)

Two critical reviews of Discipline and Punish inspired an exchange between Foucault and some prominent historians in 1978. In the texts from this exchange, Foucault addresses their criticism that, by focusing on unrealized plans and programs, such as Bentham’s Panopticon, his book lacks a sense of historical reality. Foucault replies, first, that the true aim of his book is to explore the emergence of a new type of penal rationality, not to insist that the Panopticon itself has been realized. (...) Second, he holds that types of rationality can produce distinctive sorts of effects, regardless of whether the plans and programs to which they are attached are ever fully achieved. This paper seeks to clarify Foucault’s underlying account in these responses of rationality and its efficacy. It also takes up and develops Foucault’s suggestive distinction between two different types of effects: “effects in the real” and “reality effects.”. (shrink)

The purpose of this book is to assess the merit of applying technical or economic rationality to social, legal and political problems. Diesing describes reason as calculation, discovery and application of rules to cases, and creative. Tentatively relating each type of rationality to one aspect of reason, he finally declares that creative reason "facilitates the study of social and political rationality, which are more difficult to characterize in terms of the other conceptions of reason."--C.

The article discusses the problems of the understanding of the future. The author suggests to consider this problem in accordance with the analysis of its discourse and types. He distinguishes the following kinds of temporal discourse: event time; contains the past; present; future; future reconstruction created on the basis of reconstructions of past and present; present actions in accordance with the images of future, finally, practices aimed at the implementation of the future as the plan or project. Based on (...) the analysis of several cases and general considerations the author introduces his classification of the types of the future discourse. Firstly, it is “uncertain future" (“future as a thing in itself") as the most relevant type for modernity. Secondly, it is “objectively subjective future" that could be considered both as religious vision of the future and as the rational concept allowing a person to participate in the future constructing. Thirdly, it is “local technological future" that is considered on the example of the analysis of the US and the USSR nuclear project. The current understanding of the future is analysed as an attempt to predict and to build the same future for everybody. The author argues that this attempt doesn't seem to be feasible. Implementing different ideas and projects of the future and acting spontaneously without any particular image of the future, one cannot create the same future for everyone. Probably, it is necessary to accept the fact that there're a number of images of the future and each of them is narrow. Somehow, they all are involved in the formation of the future, although we do not know how exactly. It is better to assume that any of them, even inadequate and destructive are involved in the formation and flow of social processes. That's why it is so important to analyze them in order to understand their action and place in the structure of life. (shrink)

It is generally agreed that many types of attitudinal incoherence are irrational, but there is controversy about why they are. Some think incoherence is irrational because it violates certain wide-scope conditional requirements, others (‘narrow-scopers’) that it violates narrow-scope conditional requirements. In his paper ‘The Scope of Rational Requirements’, John Brunero has offered a putative counter-example to narrow-scope views. But a narrow-scoper should reject a crucial assumption which Brunero makes, namely, the claim that we always violate conditional narrow-scope requirements when (...) we do not comply with them. I show how Brunero's objection can be met by denying this claim, and I provide independent arguments in favour of denying it. (shrink)

Inspired by recent developments in science studies, this book offers an innovative type of analysis of the recent history of rational expectations economics. In the course of exploring the multiple dimensions of rational expectations analysis, Professor Sent focuses on the work of Thomas Sargent, an instrumental pioneer in the development of this school of thought. The investigation attempts to avoid a Whiggish history that sees Sargent's development as inevitably progressing to better and better economic analysis. Instead, it provides an illustration (...) of what happened to the approach through a contextualization of Sargent's work vis-á-vis that of other scholars and ideas. The treatment aims to illuminate some of the shifting negotiations and alliances that characterize the rise and shift of direction in rational expectations economics. The Evolving Rationality of Rational Expectations won the 1998 Gunnar Myrdal Prize of the European Association for Evolutionary Political Economy for the best monograph on a theme broadly in accord with the EAEPE Theoretical Perspectives.

It is time to transcend the arid debate between rationality and ir-, a-, or non-rationality as our basic assumption about human agency.1 There are powerful arguments and extensive evidence both for and against the rationality assumption, with heavily defended entrenchments on both sides. Managers and management scholars continually make at least tacit assumptions about how they expect others to behave. If only we could have in both theory and practice the coherence and precision of rational models as (...) well as the descriptive richness of ‘behavioural’ approaches. The message of this paper is that perhaps we can. The advent of consciousness studies and, more recently, neuroeconomics would seem to indicate the way forward to transcend the opposition in some kind of synthesis. This paper investigates rationality in the light of Daniel Dennett’s thesis that it is at the core of all intentionality that is the defining characteristic of mental phenomena. Neuroeconomics seeks to enhance understanding of agency by investigating new insights on the materialist basis of mental phenomenology in the neurophysiology of the brain and nervous system. Experimental evidence mapping intentional states onto neurophysiological states is emerging, some researchers even claiming to have found a ‘neurophysiological utility function’. Dennett closes the circuit by locating the existence of brain-hardware supporting satisficing intentional choice and action as the output of evolutionary ‘design’. The dichotomy is transcended: satisficing models (of which normative optimising rational choice models are a reasonable abstraction) are a good basis both for statistical prediction of the behaviour of large numbers, and as the first base on which to construct and refine a model of expectation-formation about particular types of agent and then of individual agents. Using both the old (‘external’) and the new (sub-individual) behaviourism as well as work on unpacking the abstract notion of rationality, we can concretise optimising rational choice both generally, for epistemic theory-building purposes, and specifically for understanding and deploying models of managerial agency. Such models will need to incorporate emotion with cognition in an integrated approach. (shrink)

I present and explore a normative theory of non-doxastic attitudes like desire, hatred, and admiration. The viewpoint is general and abstract: independent of any particular flavor or source of normativity, I explore general features any acceptable way of forming these attitudes would have, especially in contrast to doxastic attitudes like belief. The first three chapters present a relatively unified picture of non-doxastic attitude formation, grounded in types of non-doxastic attitudes we can have in contrast to their impossible doxastic analogues. (...) In particular, I defend a kind of externalism; I apply it to a specific attitude, desire, to show how the approach works; and then based on a different aspect of the view, I present what I take to be some of the best ways to motivate the view, and some of the best ways to criticize it, as well. In the last chapter, I develop a theory about how these attitudes are best communicated, this time meant to capture how belief is best communicated, too, though it is inspired by certain features of non-doxastic attitudes.

Following up on previous results by Falmagne, this paper investigates possible mechanisms explaining how preference relations are created and how they evolve over time. We postulate a preference relation which is initially empty and becomes increasingly intricate under the influence of a random environment delivering discrete tokens of information concerning the alternatives. The framework is that of a class of real-time stochastic processes having interlinked Markov and Poisson components. Specifically, the occurence of the tokens is governed by a Poisson process, (...) while the succession of preference relations is a Markov process. In an example case, the preference relations are the various possible semiorders on the set of alternatives. Asymptotic results are obtained in the form of the limit probabilities of any semiorder. The arguments extend to a much more general situation including interval orders, biorders and partial orders. The results provide (up to a small number of parameters) complete quantitative predictions for panel data of a standard type, in which the same sample of subjects has been asked to compare the alternatives a number of times.

Contemporary physical theories are privileged witnesses in this respect, for in them the rational thought of phenomena makes an intrinsic use of mathematical thought, which contributes to the structuration of the formers and to the expression of their concepts. The General Theory of Relativity and the Quantum Theory are exemplar to this, as they directly reveal what can be called the “drag of physical thought par the mathematical form”, which makes possible to overcome the limitations of the physical knowledge previously adquired. This process is tightly related to the modalities and to the stucture of the rational thought underlying it. This is what we would like to show. (shrink)
