Analyzing epistemic sophistication in terms of the stringency of a person’s standards, her skills in using evidence, and her wisdom in employing proper standards, this book argues for a radical conception of epistemology as being concerned with the duties that arise during the process of belief formation.

In a highly original rereading of the writings and seminars of Jacques Lacan, together with works of Freud and others, Cassin shows how psychoanalysis, like the sophists, challenges the very foundations of scientific rationality. In taking seriously equivocations, jokes, and unfinishable projects of interpretation, the analyst, like the sophist, allows performance, signifier, and inconsistency to reshape truth.

Abstract I challenge the view that, in cases where time for deliberation is not an issue, instrumental rationality precludes myopic planning. I show where there is room for instrumentally rational myopic planning, and then argue that such planning is possible not only in theory, it is something human beings can and do engage in. The possibility of such planning has, however, been disregarded, and this disregard has skewed related debates concerning instrumental rationality.

In this paper we compare two micro foundations for modelling human behaviour and decision making. We focus on perfect strategic rationality on the one hand and a simple reinforcement mechanism on the other hand. Iterated prisoner’s dilemmas serve as the play ground for the comparison. The main lesson of our analysis is that in the space of all possible 2 × 2 PDs different micro foundations do matter. This suggests that researchers can not safely rely on the assumption that (...) implementing simple models of decision making will yield the same results that may be obtained when more sophisticated decision rules are built into the agents.

rationality has increasingly been a target of attack in contemporary educational research and practice and in its place practical reason and situated thinking have become a focus of interest. The argument here is that something is lost in this. In illustrating how we might think about the issue, this paper makes a response to the charge that as a result of his commitment to the ‘Enlightenment project’ Vygotsky holds abstract rationality as the pinnacle of thought. Against this it (...) is argued that Vygotsky had a far more sophisticated appreciation of reason and of its remit. The paper proceeds first by examining the picture of Vygotsky that is presented in the work of James Wertsch, and especially his claim that Vygotsky was an ambivalent rationalist, goes on to provide an account of Vygotsky that corrects this picture, and develops this in the light of the work of Robert Brandom, who shares Vygotsky’s inheritance of Hegel. The conclusion towards which this piece points is that the philosophical underpinnings of Vygotsky’s work provide a radically different idea of rationality and epistemology from that characterised as abstract rationality and that this has significance for education studies.

A traditional pastime of philosophers is the analysis of rhetoric and the repudiation of sophistry. Nevertheless, some of what philosophers call sophistry might rather be a subtle repudiation of the traditional principles of rationality. In this paper I start by granting the Sophist his repudiation and outline some of the obstacles to settling the dispute between Sophists and Rationalists. I then suggest that we should distinguish pragmatic Sophism from nihilistic Sophism. In the hope of driving a wedge between these (...) two I illustrate the way in which the two are confounded when Sophism is advanced by use of a particular rhetorical manoeuvre and then give an argument against nihilistic Sophism which even a nihilistic Sophist should be persuaded by.

Abstract: The standard picture of rationality requires that the agent acts so as to realize her most preferred alternative in the light of her own desires and beliefs. However, there are circumstances where such an agent can predict that she will act against her preferences. The story of Ulysses and the Sirens is the paradigmatic example of such cases. In those circumstances the orthodoxy requires the agent to be ‘sophisticated’. That is to say, she should take into account (...) her expected future choices and prevent her future self to act in certain ways. She should ‘bind’ herself to a certain course of action. This is a form of causal commitment. It is generally recognized that this form of self-commitment is the only one that is available to a rational agent. Rational commitment, where the agent gives herself a reason to act in a certain way rather than making herself act in that way, is considered not feasible. In this paper, I question this verdict. I sketch the broad outlines of a model of rational commitment, which takes as its starting point Michael Bratman’s ‘planning theory’ of intention. There are two important objections against this theory (one by John Broome and one by the Dutch philosopher Govert den Hartogh.) Both criticisms claim that such a theory is a form of ‘bootstrapping’ reasons for action into existence. In the remainder of the paper, I will defend the theory against these objections. This way, I hope to establish that defending the feasibility of rational commitment is not an obvious mistake. (shrink)

We have it on the authority of Aristotle that “reason (nous) is the best thing in us” (EN X.7, 1177a20). This idealization of reason permeates his account of eudaimonia, a term commonly translated as ‘happiness’, which Aristotle identifies with living and doing well (EN I.4, 1095a18-20). In harmony with a certain intellectualism peculiar to the mainstream of ancient philosophical accounts of eudaimonia, Aristotle holds that living well requires the unique practical application of rationality of which only humans are capable (...) (EN I.7, 1098a13-15/EE I.7, 1217a25-27). This dissertation investigates Aristotle’s substantive view on the practical application of reason by examining how, according to him, human agents use reason to decide what to do, what kind of person to be, and indeed how to live well. A distinctively human way of making decisions is deliberation (bouleusis), an exercise of practical reason par excellence. The first chapter reconstructs Aristotle’s account of deliberation from a wide range of texts in the corpus. It argues that deliberation is a complex decision-making process that, for the most part, unfolds into four stages: (1) positing a provisional goal; (2) constructing a set of alternatives; (3) identifying the best alternative; (4) forming an intention to do the most proximate action as identified in the penultimate stage. This reading offers a comprehensive representation of Aristotle’s theory while rendering his theory more sophisticated—and indeed more modern—than the alternatives in recent years. Deciding what to do often requires that we confront the question, “Which is preferable (hairetōteron) or better (beltion) between two or more options?” In Topics III, a text widely acknowledged as the inaugural treatment of the logic of preference, Aristotle articulates a set of principles to guide our preference-ranking. While scholars pay historical homage to Aristotle, there is little engagement with his treatment of preference logic. The second chapter addresses the need for a current study and reassessment of Aristotle’s preference-ranking principles. It argues that, despite differences in scope and methodology between the Aristotelian and modern systems, the description inaugural treatment of preference logic comfortably, and accurately, applies to Topics III. When one looks at the role that Aristotle allows reason to play in the production and motivation of action, it is tempting to conclude that Aristotle endorses the Humean division of labor. For Aristotle claims that deliberation is about “the things towards the goal” (EN III.3, 1112b11-16) and that virtue (aretē) makes our goals right (EN VI.12, 1144a7-9). Chapter three seeks to show, against a recent influential quasi-Humean interpretation, that the primary function of practical reason is mapping the landscape of value corresponding to the agent’s reasoned conception of what eudaimonia consists in, as a rational being that she is. Aristotle notoriously defends the political subordination of individuals he believes to have a defective deliberative capacity. In Politics I.13, he claims that the deliberative faculty is undeveloped in children and “ineffectual” (akuron) in women (1260a12). The concluding chapter considers a puzzle about the development of the female’s deliberative faculty: How do women become ineffective in their deliberation, but freemen do not, given that all children have deliberative faculties that are unperfected? Drawing from the theories defended in previous chapters, I argue that the female’s deliberative defect is primarily due to her lack of moral education rather than inalterable sexual, biological differences—a thesis widely endorsed by scholars lately.

A cursory glance at the list of Nobel Laureates for Economics is sufficient to confirm Stanovich’s description of the project to evaluate human rationality as seminal. Herbert Simon, Reinhard Selten, John Nash, Daniel Kahneman, and others, were awarded their prizes less for their work in economics, per se, than for their work on rationality, as such. Although philosophical works have for millennia attempted to describe, explicate and evaluate individual and collective aspects of rationality, new impetus was brought (...) to this endeavor over the last century as mathematical logic along with the social and behavioral sciences emerged. Yet more recently, over the last several decades, propelled by the emergence of artificial intelligence, cognitive science, evolutionary psychology, neuropsychology, and related fields, even more sophisticated approaches to the study of rationality have emerged.

Economists usually assume that rational actions are the ones motivated by a self-interested agent. However in our daily life we often see people doing altruistic actions which we praise and which we do not call irrational. How can we account for this paradox? This question and the tension underlying it, is at the heart of Philip Pettit’s classic essay, “The Virtual Reality of Homo Economicus” (1995). This dissertation constitutes a detailed analysis and evaluation of the claims that Pettit makes there, (...) in particular his original proposal of reconciliation between economic science and common sense, and the role that self-interest occupies in his model. Despite its importance, there are still few written commentaries or critiques of Pettit’s essay (1995). Among the few, most concentrate on the thesis of resilience explanation that Pettit presents at the end of the essay. What is lacking in the literature is a thorough examination of the central claim that Pettit makes there, and which gives the title to his essay: namely, the thesis of the "virtual self-interested control". In my view, this constitutes one of the most sophisticated defences of the assumption of self-interest in rational choice theory and economics. Therefore, it is surprising that it has not been subjected to more discussion, and published research. In section 1, present some of the central concepts of rational choice theory and economics, namely the homo economicus. In section 2, I introduce Pettit’s model, and then evaluate in which sense it is a plausible model to explain the behaviour in non-market contexts. Section 3 presents my criticism of the shortcomings of the model. (shrink)

The Stoic, David Hume’s “man of action and virtue,” is often considered the forerunner and foundation of Adam Smith’s market man of morals (Hume 1985, 146–54). Ian Simpson Ross notes Smith’s enthusiasm for Stoic philosophers such as Cicero and Marcus Aurelius and the way Stoic philosophy informs Smith’s arguments on various topics such as self-command, self-love, and suicide (Ross 1995, 172, 384). Pierre Force confirms the influence of Stoicism in tracing Smith’s moral system as a contrast with the Epicurean/Augustinian tradition, (...) showing that for Smith and Stoics self-love merely points the way for an agent to choose rationally a course of action (Force 2003, 103–5).

Is it possible to recognize the limits of rationality, and thus to embrace moral pluralism, without embracing moral relativism? My answer is yes; nevertheless, certain anti-foundational positions, both recent and ancient, take a cynical stance toward the possibility of any critical moral judgment, and as such, must be regarded as relativistic.1 It is such cynicism, I argue, whether openly announced or unknowingly implied, that marks the distinction between relativism and pluralism.2 The danger of this cynicism is not so much (...) that it renders the categorical acceptance of a particular moral view unattainable, but that it renders categorical condemnation of any particular position (or action) impossible.3 Two ..

I argue here that sophisticated AI systems, with the exception of those aimed at the psychological modeling of human cognition, must be based on general philosophical theories of rationality and, conversely, philosophical theories of rationality should be tested by implementing them in AI systems. So the philosophy and the AI go hand in hand. I compare human and generic rationality within a broad philosophy of AI and conclude by suggesting that ultimately, virtually all familiar philosophical problems (...) will turn out to be at least indirectly relevant to the task of building an autonomous rational agent, and conversely, the AI enterprise has the potential to throw light at least indirectly on most philosophical problems.

The Humean conception of the self consists in the belief-desire model of motivation and the utility-maximizing model of rationality. This conception has dominated Western thought in philosophy and the social sciences ever since Hobbes’ initial formulation in Leviathan and Hume’s elaboration in the Treatise of Human Nature. Bentham, Freud, Ramsey, Skinner, Allais, von Neumann and Morgenstern and others have added further refinements that have brought it to a high degree of formal sophistication. Late twentieth century moral philosophers such as (...) Rawls, Brandt, Frankfurt, Nagel and Williams have taken it for granted, and have made use of it to supply metaethical foundations for a wide variety of normative moral theories. But the Humean conception of the self also leads to seemingly insoluble problems about moral motivation, rational final ends, and moral justification. Can it be made to work? (shrink)

An influential tradition in moral philosophy attempts to explain an immoral action by reference to the defect in reasoning on the part of an immoral agent. On this view, the requirements of morality are not only sanctioned by the more general requirements of rationality, but the violations of the moral requirements would be indicative of a rational failure. In this article I argue that ascription of irrationality to amoral individuals (e.g., psychopaths) is either empirically false, or else, conceptually problematic. (...) An interpretation of irrationality in its instrumental sense fails to do justice to the results of the research concerning the intelligence of some amoralists, whereas the suggestion that the alleged cognitive deficiency lies at the level of final ends and ultimate values faces serious theoretical difficulties. All attempts to construe the notion of an external reason for action without reference to the agent's actual goals and values bespeak an objectivist's bias, rest on controversial assumptions, and tend to alienate the agent from the proposed set of reasons. The argument is partly based on the analysis of reasoning of Ted Bundy, a notorious serial murderer, who presents a rather sophisticated justification for his criminal behavior. (shrink)

This essay argues that Aristotle's categories of oratory are not as useful in judging the methods of Sophistical rhetoric as his presentation of time. The Sophistical argumentative method of “making the weaker the stronger case” is re-evaluated as a political practice. After showing this argument's relation to power and ideology, Aristotle's philosophy, which privileges a procedure of argument consistent with the politics of a polis-ideal rhetoric, is offered as reason for objecting to Sophistical rhetoric. The essay concludes that Sophistical rhetoric (...) prefers the concept of possibility over Aristotelian actuality, and offers a need for an ideological space of radical, generative possibility in rhetorical theory.

Can rational agents coordinate in simultaneous interactions? According to standard game theory they cannot, even if there is a uniquely best way of doing so. To solve this problem we propose an argument in favor of ‘belief-less reasoning’, a mode of inference that leads to converge on the optimal solution ignoring the beliefs of the other players. We argue that belief-less reasoning is supported by a commonsensical Principle of Relevant Information that every theory of rational decision must satisfy. We show (...) that this principle can be used to justify (some versions of) team reasoning, as well as other schemes of practical reasoning that do not involve sophisticated meta-representation. (shrink)

To summarize, in order for rational agents to be able to engage in the sophisticated kinds of reasoning exemplified by human beings, they must be able to introspect much of their cognition. The problem of other minds and the problem of knowing the mental states of others will arise automatically for any rational agent that is able to introspect its own cognition. The most that a rational agent can reasonably believe about other rational agents is that they have rational (...) architectures similar to its own, and that they have thoughts related to their rational architectures in certain ways. This leads to Rational Functionalism as an account of what it is to be a cognizer having mental states. That in turn entails that a computer can be a person in precisely the same sense as my next door neighbor if it can appropriately mimic my rational architecture. There is nothing I could know about my neighbor that I could not believe with equal justification about the computer. Rational Functionalism also makes it reasonable to define the narrow content of a thought to be its overall place in the agent's rational architecture, that is, its conceptual role. This is, however, avery narrow notion of content. For practical purposes, we are not interested in knowing the narrow contents of other people's thoughts. We are only interested in rather general properties of those narrow contents. This is what is expressed by the use ofthat-clauses in public language. (shrink)

[This version of the paper has been superseded by "Reason-based choice and context-dependence: An explanatory framework", forthcoming in Economics & Philosophy.] -/- We introduce a “reason-based” way of rationalizing an agent’s choice behaviour, which explains choices by specifying which properties of the options or choice context the agent cares about (the “motivationally salient properties”) and how he or she cares about these properties (the “fundamental preference relation”). Reason-based rationalizations can explain non-classical choice behaviour, including boundedly rational and sophisticated rational (...) behaviour, and predict choices in unobserved contexts, an issue neglected in standard choice theory. We characterize the behavioural implications of different reason-based models and distinguish two kinds of context-dependent motivation: “context-variant” motivation, where the agent cares about different properties in different contexts, and “context-regarding” motivation, where the agent cares not only about properties of the options, but also about properties relating to the context.

Cohen (1981) and others have made an interesting argument for the thesis that humans are rational: normative principles of reasoning and actual human reasoning ability cannot diverge because both are determined by the same process involving our intuitions about what constitutes good reasoning as a starting point. Perhaps the most sophisticated version of this argument sees reflective equilibrium as the process that determines both what the norms of reasoning are and what actual cognitive competence is. In this essay, I (...) will evaluate both the general argument that humans are rational and the reflective equilibrium argument for the same thesis. While I find both accounts initially appealing, I will argue that neither successfully establishes that humans are rational. (shrink)

ABSTRACTJames Woodward and John Allman [2007, 2008] and Peter Railton [2014, 2016] argue that our moral intuitions are products of sophisticated rational learning systems. I investigate the implications that this discovery has for intuition-based philosophical methodologies. Instead of vindicating the conservative use of intuitions in philosophy, I argue that what I call the rational learning strategy fails to show philosophers are justified in appealing to their moral intuitions in philosophical arguments without giving reasons why those intuitions are trustworthy. Despite (...) the fact that our intuitions are outputs of surprisingly sophisticated learning mechanisms, we do not have reason to unreflectively trust them when offering arguments in moral philosophy.

I attempt here to draw parallels between ancient and modern sophistry —and ancient and modern philosophy. Plato at one point identified a sophist as a paid hunter of rich young men who ‘lurks’ in non-being: that is, has no concern for truth. In more modern times Elizabeth Anscombe, when asked what her philosophical colleagues did, remarked that they spend most of their time corrupting the youth. And the present situation in many liberal universities encourages them to do so—and in the (...) humanities more generally, not only in philosophy. By the time a PhD candidate has completed his doctorate, joined a department and eventually got tenure, he will in many cases have become a practised sophist, equipped with what often amounts to a PhD in rationalizing, that is, in sophistry. I wonder whether we ought not to do something to change some of that. (shrink)

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis’s project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is (...) vulnerable. We pose a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made. (shrink)

Following Kuhn's main thesis according to which theory revision and acceptance is always paradigm relative, I propose to outline some possible consequences of such a view. First, asking the question in what sense Bayesian decision theory could serve as the appropriate (normative) theory of rationality examined from the point of view of the epistemology of theory acceptance, I argue that Bayesianism leads to a narrow conception of theory acceptance. Second, regarding the different types of theory revision, i.e. expansion, contraction, (...) replacement and residuals shifts, I extract from Kuhn's view a series of indications showing that theory replacement cannot be rationalized within the framework of Bayesian decision theory, not even within a more sophisticated version of that model. Third, and finally, I will point to the need for a more comprehensive model of rationality than the Bayesian expected utility maximization model, the need for a model which could better deal with the different aspects of theory replacement. I will show that Kuhn's distinction between normal and revolutionary science gives us several hints for a more adequate theory of rationality in science. I will also show that Kuhn is not in a position to fully articulate his main ideas and that he well be confronted with a serious problem concerning collective choice of a paradigm. (shrink)

In this essay, I explore the parallel between the historical exclusions of rhetoric from philosophy and of women from fields of rational discourse. After considering the usefulness and limitations of deconstruction for exposing marginalization by hierarchical systems, I explore links between texts of the sophists and feminist proposals for rewriting/rereading history by Cixous, Spivak, and others. I conclude that sophistic rhetoric offers a flexible alternative to philosophy as an intellectual framework for mediating theoretical oppositions among contemporary feminisms.

John Searle claims that reasoning requires libertarian free will. He hopes this can be reconciled with a naturalistic neuroscience through a sophisticated theory of emergence, which includes indeterminism, and topdown causation.

_Tracing practical reason from its origins to its modern and contemporary permutations_ The Greek discovery of practical reason, as the skilled performance of strategic thinking in public and private affairs, was an intellectual breakthrough that remains both a feature of and a bug in our modern world. Countering arguments that rational choice-making is a contingent product of modernity, _The Greeks and the Rational_ traces the long history of theorizing rationality back to ancient Greece. In this book, Josiah Ober explores (...) how ancient Greek sophists, historians, and philosophers developed sophisticated and systematic ideas about practical reason. At the same time, they recognized its limits—that not every decision can be reduced to mechanistic calculations of optimal outcomes. Ober finds contemporary echoes of this tradition in the application of game theory to political science, economics, and business management. _The Greeks and the Rational_ offers a striking revisionist history with widespread implications for the study of ancient Greek civilization, the history of thought, and human rationality itself.

The paper is concerned with the role of the logos in the sophistic thought.

This interest in the power (...) of "logos" leads the Sophists such as Protagoras, Gorgias, Antiphon to develop the techniques which aim at increasing the persuasive power of speech by addressing both rational and emotional part of the soul.

Moving from simple to increasingly sophisticated candidate cases, I argue against the idea that there can be cases in which, due to no fault of the agent or to any ambiguity regarding how things will go depending on which option is selected, all the options available to an agent are rationally impermissible. Whether there are cases that fit this bill—qualifying as what I will label no-fault-or-ambiguity rational dilemmas—depends on the characteristics of conclusive reasons. My reasoning leads me to the (...) view that a key feature of conclusive reasons is that they capture or ground overall assessments that are relationally significant. I then argue that, while this view does not itself conflict with the most sophisticated candidate cases of purported dilemmas of the relevant sort, following the spirit of the view does lead to a conclusion that blocks counting even these cases as ones in which there is a conclusive reason against every available option. My conclusion is that there is no solid basis for the view that there are cases of no-fault-or-ambiguity rational dilemmas. (shrink)

We describe the results of an experiment on decision making in an insurance context. The experiment was designed to test for the underlying rationality of insurance consumers, where rationality is understood in usual economic terms.

We find that there the discrepancy from (...) rational decision making increases with the sophistication of the rationality criteria, that irrationality concerning fair premium contracts is uncharacteristically high, and that the slope of absolute risk aversion seems to depend on the format of the insurance contract.

It is indeed important to identify the rich variety of systems for the adaptive control of behaviour, rather than squeezing this richness into a few boxes. We need to recognise both the variety of systems for the cognitive control of adaptive behaviour and to chart the relationships between such systems. But I shall argue that these projects are not best pursued by asking about the extent of animal rationality. The argument develops in three stages. The first outlines a picture (...) of the selective regimes that drive the evolution of the sophisticated use of information by animal agents. The second argues that hominid cognition has evolved in response to a somewhat different set of " 3 " challenges and that the transmission of social information and skill has come to be both a critical and an unusual feature of hominid selective and developmental environments. The third draws upon the ideas of Dan Sperber and others in arguing that the social transmission of information introduces a vetting problem. I shall suggest that we see rationality as an evolved response to this vetting problem. (shrink)

This paper investigates the responses of GPT-4, a state-of-the-art AI language model, to ten prominent philosophical paradoxes, and evaluates its capacity to reason and make decisions in complex and uncertain situations. In addition to analyzing GPT-4's solutions to the paradoxes, this paper assesses the model's Theory of Mind (ToM) capabilities by testing its understanding of mental states, intentions, and beliefs in scenarios ranging from classic ToM tests to complex, real-world simulations. Through these tests, we gain insight into AI's potential for (...) social reasoning and its capacity for more sophisticated forms of human-AI interaction. The paper also explores the limitations and biases of AI-generated reasoning and its implications for our comprehension of complex philosophical problems. (shrink)

It is no longer the fashion to imagine Herodotos a liar when he tells marvellous stories, for some of his most extraordinary statements have long since been shown to contain at least a substantial measure of truth. It is perhaps not sufficiently realized, however, that on occasion he misleads his readers and himself by too much critical unbelief in his materials and consequent application of the crude methods of mythological investigation then current. In other words, he often rationalizes in the (...) only way then possible, superficially altering the story so as to rid himself of the incredible details, or at all events, as I think, attributing to the actors motives which a somewhat drily rational mind could understand and approve or condemn. It is of course well known that at least the former method was a commonplace of the sophists, whose influence on Herodotos is manifest and widespread; it has been said, indeed, that it is much older than they and characteristically Ionic. L. Radermacher finds traces of it in the Odyssey itself and adds that, although we can sometimes catch the rationalizer at work, we cannot be sure of always doing so and ‘müssen annehmen, dass der Glaube an die Geschichtlichkeit ihrer Sage manche griechischen Autoren früh verführt hat, sie geschichtlicher zu erzählen als eigentlich erlaubt war’. This is a true and useful statement. Modern criticism has long learned to set aside ancient allegorizations of myths, about which I need say nothing, for the subject has been repeatedly and well handled by my colleague, Dr. J. Tate; it has often, however, confused ancient interpretation of myth with ancient criticism of saga. Euhemerism indeed is usually recognized for what it is, although even this is not always so; but uixere inepti ante Euhemerum multi, and their efforts are by no means always distinguished either from allegorizing or from real sagas. For an example of the former confusion I may refer to Stallbaum's note on Plato, Phaedrus, 29 C-D, where the reader is referred to the account given by Lobeck of the rise and growth of allegorization. But Plato says nothing at all of allegories in this passage. He quotes, with ironical admiration of its ‘wisdom’, a version of the story of Boreas and Oreithyia according to which she. was knocked off the Areiopagos, or some other place, by a strong north wind, and so was killed and consequently said to have been carried away by Boreas. He adds that it would be a laborious and dismal business to go through all the tales of wonder in that way, rationalizing the Hippocentaurs, Gorgons, Chimaira, Pegasos, and the rest out of existence; a wise saying which was uttered in vain for Palaiphatos and his kind. However, most moderns know a myth from a saga and an allegory from a crude rationalization which accepts the story as true except for the incredibilities and is quite ready to believe, for instance, in Romulus if we will but postulate that he was not snatched up to heaven but murdered and his body hidden. There is a much more subtle snare, consisting of a story which, although rationalized, is well told, and Herodotos in this respect can be a notable offender, for he never tells a story ill. (shrink)

It would be very difficult to discuss the question concerning the hypothesis of omniscience in microeconomics without relating this hypothesis to the more fundamental hypothesis of rationality (usually referred to as rationality principle or postulate) which is at the base of the very idea of an economic theory and even social sciences. Indeed omniscience is a quality which was typically attributed to homo oeconomicus whose essential characteristic is to be perfectly "rational". This association between omniscience and rationality (...) goes back to the marginalist revolution which progressively brought economists to model economic agents as rational calculators who make each decision by systematically maximizing their utility through the standard application of more or less sophisticated mathematical methods. But since the very idea of such a maximization has no meaning if all relevant parameters and variables are not carefully taken into account, it became relatively common to associate omniscience (the required knowledge of such parameters and variables) and rationality (the disposition to make decisions which tend to maximize the degree of success in reaching a goal).

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Salomon Maimon: Rational Dogmatist, Empirical Skeptic: Critical AssessmentsDaniel BreazealeGideon Freudenthal, editor. Salomon Maimon: Rational Dogmatist, Empirical Skeptic: Critical Assessments. Dordrecht: Kluwer, 2003. pp vii + 304. Cloth, $135.00.This collection of previously unpublished essays on one of the more idiosyncratic and complex figures in the history of philosophy begins with a splendid introductory essay by the editor, "A Philosopher between Two Cultures," emphasizing the "inter-cultural" character of Maimon's achievement (...) and his position as an outsider with respect to both the traditional Jewish community and that of modern German philosophy, a position reflected in Maimon's strategy of advancing his systematic philosophy by means of eccentric "commentaries" on such authors as Maimonides, Newton, and Kant.Maimon's "dual cultural project" is also the theme of a fine essay by Yossif Schwartz, "Causa materialis: Solomon Maimon, Moses ben Maimon and the Possibility of Philosophical Transmission," which compares Maimon's effort to introduce his Hebrew readers to Kantian philosophy (in his commentary on The Guide of the Perplexed) and his German-language readers to Maimonides (in his Autobiography), in an effort to legitimize modern philosophy to his fellow Jews and Maimonides and the tradition of Jewish thought to his fellow philosophers. Schwartz illustrates this point with reference to the specific issue of God as "material cause" of the world.Several of the essays deal with the difficult but important theme of predication and with Maimon's central notion of the "principle of determinability," understood as the highest principle of all (real) synthetic judgments. Oded Schechter's "The Logic of Speculative Philosophy and Skepticism in Maimon's Philosophy: Satz der Bestimmbarkeit and the Role of Synthesis" analyzes this theme in considerable technical detail and relates it to Maimon's philosophy as a whole, and indeed to the "speculative logic" of Hegel and others. This is certainly one of the richest (as well as one of the more challenging) essays in the collection, containing illuminating discussions not only of the principle of determinability, but also of Maimon's highly original notions of "synthesis" and "construction." More accessible is Elhanan Yakira's "From Kant to Leibniz? Salomon Maimon and the Question of Predication," which not only clearly explains the principle in question but convincingly disputes the widespread view that this represents a return to Leibnizian rationalism on the part of Maimon.Maimon's poorly understood theory of "the differential" is the theme of the contribution by Michael Roubach, "Salomon Maimon's Philosophy and its Place in the Enlightenment: Wandering in the Land of Difference," which interprets this notion in the context of the difference between the finite and the infinite intellect and stresses the difference between Maimon's position and that of pre-Kantian rationalism. Unfortunately, Roubach's effort to clarify Maimon's position by comparing it to that of Giles Deleuze is too brief and obscure to be helpful.Though Maimon's relationship to Kant is at least touched on in almost every essay in this collection, it is the explicit theme of four of them, three of which dwell on Maimon's [End Page 119] so-called "quid facti" challenge to Kant's deduction of the categories. Peter Thielke's "Intuition and Diversity: Kant and Maimon on Space and Time" is a very long and philosophically sophisticated examination of Maimon's direct challenge to Kant's "discursivity thesis" regarding the heterogeneity of the faculties of sensibility and understanding. Thielke focuses on Kant's account of space and time as pure forms of intuition and contrasts this with what he calls Maimon's "neglected alternative," viz.: that space and time are not forms of intuition at all, but rather "forms of diversity" and hence features of the function of thinking. In order to explicate this difficult theory, Thielke offers an impressive reconstruction of Maimon's fiendishly obscure idea of the "differentials of pereption" and hence of the fundamentally productive character of the understanding. This provides the theoretical foundation for Maimon's non-dualistic account of the cognitive faculties and his non-causal account of the mind's passivity. Thielke concludes that Maimon's objections, if not sufficient to overturn the discursivity thesis, still undermine the evidence for the same... (shrink)

The underlying skepticism of ancient Greek culture made it unreceptive of philosophy. It was the Catholic Church that embraced philosophy. Still, Étienne Gilson reminds us in Reason and Revelation in the Middle Ages that some early Christians rejected philosophy. Their rejection was based on fideism: the view that faith alone provides knowledge. Philosophy is unnecessary and dangerous, fideists argue, because (1) anything known by reason can be better known by faith, and (2) reason, on account of the sin of pride, (...) seeks to replace faith. To support this twofold claim, fideists, like Tertullian and Tatian, quote St. Paul. However, a judicious interpretation of St. Paul’s remarks show that he does not object to philosophy per se but to erroneous philosophy. This interpretation is reinforced by St. Paul’s own background in philosophy and by his willingness to engage intellectuals critical of Christianity in the public square. The challenge of fideism brings up the interesting question: what would Jesus himself say about the discipline of philosophy? Could it be that Jesus himself was a philosopher (as George Bush once declared)? As the fullness of wisdom and intelligence, Jesus certainly understood philosophy, although not in the conventional sense. But surely, interpreting his life through the lens of fideism is unconvincing. Instead, an appreciation of his innate philosophical skills serves better to understand important elements of his mission. His perfect grasp of how grace perfects nature includes a philosophy of the human person. This philosophy grounded in common-sense analysis of human experience enables Jesus to be a profound moral philosopher. Specifically, he is able to explain the principles of personal actualization. Relying on ordinary experience, where good philosophy must start, he narrates moral lessons—parables—that illumine difficulties regarding moral responsibility and virtue. These parables are accessible but profound, showing how moral understanding must transcend Pharisaical legalism. Additionally, Jesus’ native philosophical power shows in his ability to explain away doctrinal confusions and to expose sophistical traps set by his enemies. If fideism is unconvincing, and if the great examples of the Patristics, the Apostles, and Jesus himself show an affinity for philosophy, then it is necessary to conclude that Christianity is a rational religion. Accordingly, the history of Christian culture is arguably an adventure in faith and reason. Since God is truth and the author of all truths, there is nothing in reality that is incompatible with Christian teaching. As John Paul II explains effectively in the encyclical, Fides et Ratio, Christianity is a religion that is rational and can defend itself. This ability to marshal a defense makes Christianity a religion for all seasons. (shrink)

The connection between Adam Smith and Alasdair MacIntyre is not evident at first glance. In fact, those who know MacIntyre’s work might bristle at the association. MacIntyre is inherently anticapitalist. He believes that moral people ought to reject the modern state and large-scale corporations.1 He also rejects what he terms the enlightenment project, claiming not only that it failed but that it was doomed to do so.2 Furthermore, MacIntyre’s perspectivalism seems to run counter to any “impartial spectator” theory such as (...) Smith ’s; tradition-bound rationality necessarily assumes partiality.3 In short, MacIntyre regards himself as an opponent of the liberal tradition, that intellectual lineage which is most closely associated with Smith, and, although he rejects association with communitarianism, he holds a similar place in contemporary philosophy. He is liberalism’s critic, not its reformer. But ethics makes strange bedfellows. MacIntyre’s theory of rationality, I contend, provides a useful and important complement to Smith ’s moral psychology. It allows for the intermingling of emotion and reason that is so important for Smith ’s work.4 It creates a structure for bridging Smith ’s individuals and the communities of which they are a part. In essence, I argue, MacIntyre’s work allows us to better understand Smith ’s jump from deliberation on the individual level to the development of cultural standards and norms. I conclude that Smith ’s emphasis on the individual results in an incomplete theory of communal rationality, and that MacIntyre’s emphasis on tradition leaves out a foundation of individual agency. The two theories, however complement each other well. As a bit of preparation, it is worth mentioning that both thinkers, and Smith, in particular, are often portrayed inaccurately. Smith is not the self-interest focused libertarian that he is made out to be. He is, instead a sophisticated moral theorist whose first book, The Theory of Moral Sentiments was celebrated and influential in its time. (shrink)

When we ask a decision maker to express her preferences, it is typically assumed that we are eliciting a pre-existing set of preferences. However, empirical research has suggested that our preferences are often constructed on the fly for the decision problem at hand. This paper explores the ramifications of this empirical research for our understanding of instrumental rationality. First, I argue that these results pose serious challenges for the traditional decision-theoretic view of instrumental rationality, which demands global coherence (...) amongst all of one's beliefs and desires. To address these challenges, I first develop a minimal notion of instrumental rationality that issues in localized, goal-relative demands of coherence. This minimal conception of instrumental rationality is then used to offer a more sophisticated account of the global aspects of instrumental rationality. The resulting view abandons all-or-nothing assessments of rationality and allows us to evaluate decision makers as being rational to varying degrees. My aim is to propose a theory that is both psychologically and normatively plausible. (shrink)

In a world of partially overlapping and partially conflicting interests there is good reason to doubt that self-seeking behaviour at the micro-level will spontaneously lead to desirable social outcomes at the macro-level. Nevertheless, some sophisticated economic writers advocating a laissez-faire policy prescription have proposed various 'invisible hand' mechanisms which can supposedly be relied upon to 'educe good from ill'. Smith defended the 'simple system of natural liberty' as giving the greatest scope to the unfolding of God's will and the (...) working out of 'natural' providential processes free of interference by 'artificial' state intervention - the expression not of divine order but of fallible human reason. Hayek, adopting a similar policy stance, based it in an evolutionary process in which those institutional forms best adapted to reconciling individual interests would, he believed, spontaneously be selected for in the inter-group struggle for survival. Keynes shares the holistic approach of Smith and Hayek, but without their reliance on invisible hand mechanisms. If spontaneous processes cannot be relied upon to generate desirable social outcomes then we have to take responsibility for achieving this ourselves by establishing the appropriate institutional framework. Keynes takes a historical view of the role of capitalism and analyses its pathology as rooted in what we would now refer to as a multi-player prisoners' dilemma. The paper draws out the significance of his methodological standpoint here. Keynes's policy standpoint assigns a critical role to his own class, the 'educated bourgeoisie' in the reform process he maps out. A distinction, but also an intimate connection, is highlighted between, on the one hand, micro-level individualism (the 'Manchester System, and, on the other, the macro-level collective action ('planning') required to preserve it. Finally Keynes is considered in relation to the themes of laissez-faire, holism, reductionism, providentialism and the invisible hand. (shrink)

Reasoning may be defined as a deliberate effort to coordinate inferences so as to reach justifiable conclusions. Thus defined, reasoning includes collaborative as well as individual forms of cognitive action. The purpose of the present study was to demonstrate a circumstance in which collaborative reasoning is qualitatively superior to individual reasoning. The selection task, a well known logical hypothesis-testing problem, was presented to 143 college undergraduates-32 individuals and 20 groups of 5 or 6 interacting peers. The correct (falsification) response pattern (...) was selected by only 9% of the individuals but by 75% of the groups. The superior performance of the groups was due to collaborative reasoning rather than to imitation or peer pressure. Groups typically co-constructed a structure of arguments qualitatively more sophisticated than that generated by most individuals. The results support Piagetian and Habermasian views of peer interaction as a locus of rational social processes. (shrink)

In Moral Education in a Secular Society, Paul Hirst offers accounts of the content and justification of morality and the aims and methods of moral education. My own recent book, A Theory of Moral Education, does the same. Here I explore the similarities and differences between our theories. In the first part of the paper, I outline what Hirst calls the ‘sophisticated view of education’, which I wholeheartedly endorse, and highlight his attention to the noncognitive as well as the (...) cognitive aspects of morality. In the second part, I explain how Hirst’s transcendental justification of morality differs from my contractarian justification and trace the implications of this difference for our respective accounts of moral education.

There has been a long tradition of interpreting Plato as a rational egoist. Over the past few decades, however, some scholars have challenged this reading. While Rational Egoism appeals to many ordinary folk, in sophisticated philosophical circles it has fallen out of favor as a general and complete account of the nature of reasons for action. I argue that while the theory of practical rationality that is often equated with rational egoism—a view that I call ‘Simple-Minded Rational Egoism'—is (...) neither plausible nor endorsed by Plato in his Republic, there is a more complex version of Rational Egoism to which Plato is indeed committed. Moreover, such a conception of practical rationality is not vulnerable to the standard set of objections that contemporary philosophers have made against Rational Egoism. (shrink)
