Closure for justification is the claim that thinkers are justified in believing the logical consequences of their justified beliefs, at least when those consequences are competently deduced. Many have found this principle to be very plausible. Even more attractive is the special case of Closure known as Single-Premise Closure. In this paper, I present a challenge to Single-Premise Closure. The challenge is based on the phenomenon of rational self-doubt – it can be rational to be less than fully confident in (...) one's beliefs and patterns of reasoning. In rough outline, the argument is as follows: Consider a thinker who deduces a conclusion from a justified initial premise via an incredibly long sequence of small competent deductions. Surely, such a thinker should suspect that he has made a mistake somewhere. And surely, given this, he should not believe the conclusion of the deduction even though he has a justified belief in the initial premise. (shrink)

In public political deliberation, people will err and lie in accordance with definite patterns. Such discourse failure results from behavior that is both instrumentally and epistemically rational. The deliberative practices of a liberal democracy cannot be improved so as to overcome the tendency for rational citizens to believe and say things at odds with reliable propositions of social science. The theory has several corollaries. One is that much contemporary political philosophy can be seen as an unsuccessful attempt to vindicate, (...) on symbolic and moral grounds, the forms that discourse failure take on in public political deliberation. Another is that deliberative practices cannot be rescued even on non-epistemic grounds, such as social peace, impartiality, participation, and equality. To alleviate discourse failure, this book proposes to reduce the scope of majoritarian politics and enlarge markets. (shrink)

In a book and a series of articles Harold I. Brown has presented “the new theory of science”, which he characterizes as a “modest historicism”. I propose to examine Brown's contribution to the current debate on scientific method, and to show the inadequacy of his proposals. In particular, I want to concentrate on a fundamental concern of Brown's, namely, rationality.

We respond to recent comments on our proposal to improve justice in ventilator triage, in which we used as an example New Jersey’s publicly available and legally binding Directive Number 2020-03. We agree with Bernard Lo and Doug White that equity implications of triage frameworks should be continually reassessed, which is why we offered six concrete options for improvement, and called for monitoring the consequences of adopted triage models. We disagree with their assessment that we mis-characterised their Model Guidance, as (...) included in the NJ Directive, in ways that undermine our conclusions. They suggest we erroneously described their model as a two-criterion allocation framework; that recognising other operant criterion reveals it ‘likely mitigate[s] rather than exacerbate[s] racial disparities during triage’, and allege that concerns about inequitable outcomes are ‘without evidence’. We highlight two major studies robustly demonstrating why concerns about disparate outcomes are justified. We also show that White and Lo seek to retrospectively—and counterfactually—correct the version of the Model Guideline included in the NJ Directive. However, as our facsimile reproductions show, neither the alleged four-criteria form, nor other key changes, such as dropping the Sequential Organ Failure Assessment score, are found in the Directive. These points matter because our conclusions hence stand, because the public version of the Model Guidance had not been updated to reduce the risk of inequitable outcomes until June 2021 and NJ’s Directive still does not reflect these revisions, and, hence, represents a less equitable version, as acknowledged by its authors. We comment on broader policy implications and call for ways of ensuring accurate, transparent and timely updates for users of high-stakes guidelines. (shrink)

This paper considers how cognitive architecture impacts and constrains the rational requirement to respond to reasons. Informational encapsulation and its close relative belief fragmentation can render an agent’s own reasons inaccessible to her, thus preventing her from responding to them. For example, someone experiencing imposter phenomenon might be well aware of their own accomplishments in certain contexts but unable to respond to those reasons when forming beliefs about their own self-worth. In such cases, are our beliefs irrational for failing to (...) respond to our own reasons? Or are they excused on grounds of the reasons’ inaccessibility? I argue that in such cases, the rational status of the belief that fails to respond to reasons is modulated by the degree of encapsulation of the system that produces it. Yet because our cognitive systems are rarely perfectly encapsulated, our failures to respond to reasons are almost always irrational to some degree. (shrink)

We ordinarily suppose that there is a difference between having and failing to exercise a rational capacity on the one hand, and lacking a rational capacity altogether on the other. This is crucial for our allocations of responsibility. Someone who has but fails to exercise a capacity is responsible for their failure to exercise their capacity, whereas someone who lacks a capacity altogether is not. However, as Gary Watson pointed out in his seminal essay ’Skepticism about Weakness of Will’, (...) the idea of an unexercised capacity is much more difficult to make sense of than it initially appears. The aim of ’Rational Capacities’ is to provide the needed explication of this idea. (shrink)

Extended Rationality: A Hinge Epistemology provides a novel account of the structure of epistemic justification. Its central claim builds upon Wittgenstein's idea in On Certainty that epistemic justifications hinge on some basic assumptions and that epistemic rationality extends to these very hinges. It exploits these ideas to address major problems in epistemology, such as the nature of perceptual justifications, external world skepticism, epistemic relativism, the epistemic status of basic logical laws, of the Principle of the Uniformity of Nature, (...) of our belief in the existence of the past and of other minds, and the nature of testimonial justification. Along the way, further technical issues, such as the scope of the Principle of Closure of epistemic operators under known entailment, the notion of transmission failure, and the existence of entitlements are addressed in new and illuminating ways.

We are fallible creatures, prone to making all sorts of mistakes. So, we should be open to evidence of error. But what constitutes such evidence? And what is it to rationally accommodate it? I approach these questions by considering an evolutionary debunking argument according to which (a) we have good, scientific, reason to think our moral beliefs are mistaken, and (b) rationally accommodating this requires revising our confidence in, or altogether abandoning the suspect beliefs. I present a dilemma for such (...) debunkers, which shows that either we have no reason to worry about our moral beliefs, or we do but we can self-correct. Either way, moral skepticism doesn’t follow. That the evolutionary debunking argument fails is important; also important, however, is what its failure reveals about rational belief revision. Specifically, it suggests that getting evidence of error is a non-trivial endeavor and that we cannot learn that we are likely to be mistaken about some matter from a neutral stance on that matter.

The flu has an interesting history with respect to health care rationing in the United States. Consider that just about two years ago, the American public faced a shortage of influenza vaccine. Dire predictions were made about how many people might perish, and rationing protocols were created. However, many of the rationing protocols were ignored. Luckily, that flu season did not result in the horrible fatalities that were predicted. For these reasons, problems of health care rationing around issues of the (...) flu were postponed, rather than resolved.Over the last year, the public has focused its anxious attention on the possible avian influenza pandemic. Last week I noticed that at least once each day I heard mention in some discussion or another of the threat of this disease becoming easily transmissible from human to human. (shrink)

This paper studies the attempts (and failure) of Russian revolutionaries to mobilize the peasantry in the decade leading to the Soviet revolution of 1917. Peasants, who had been emancipated from serfdom only four decades earlier, in 1861, were still largely propertyless and poor. This would, at first glance, make them a ripe target for revolutionary activity. But peasants were largely refractory. We explain this lack of revolutionary spirit through two models. First, despite their lack of education and political awareness, (...) the peasants were rational in their refusal to participate in revolutionary activity; they engaged in a cost–benefit calculus which pushed them away from revolt and political organization. Second, based on the Wildavsky–Thompson cultural types, Russian peasants were largely fatalist: they believed they had no influence on the world, so it was not worth attempting to change it. This paper sheds light on some aspects of the Russian revolution, but also encourages further research in history and economic sociology on the interaction between culture and incentives. (shrink)

This article provides a discussion of the principle of transmission of evidential support across entailment from the perspective of belief revision theory in the AGM tradition. After outlining and briefly defending a small number of basic principles of belief change, which include a number of belief contraction analogues of the Darwiche-Pearl postulates for iterated revision, a proposal is then made concerning the connection between evidential beliefs and belief change policies in rational agents. This proposal is found to be suffcient to (...) establish the truth of a much-discussed intuition regarding transmission failure. (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)

Some combinations of attitudes--of beliefs, credences, intentions, preferences, hopes, fears, and so on--do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"--that is, correctly (...) responding to one's reasons. -/- In *Fitting Things Together*, Alex Worsnip pushes back against this trend--defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. -/- Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.

Schervish (1985b) showed that every forecasting system is noncalibrated for uncountably many data sequences that it might see. This result is strengthened here: from a topological point of view, failure of calibration is typical and calibration rare. Meanwhile, Bayesian forecasters are certain that they are calibrated---this invites worries about the connection between Bayesianism and rationality.

Summary For Thomas Edison, experiencing a failure did not mean that he had failed. Through an examination of the process that led to his invention of the carbon microphone, I argue that his positive approach to failure contributed both to his success as an inventor and to the functional success of his inventions. Edison's laboratory notebooks and legal testimony reveal that his seemingly erratic approach and reliance on trial and error methods in fact had a consistent direction and (...) a rational basis, well suited to the under-determined problems he faced. The outcome of this process, the carbon microphone, contributed significantly to the commercial success of the telephone and remains in use today. Thomas Hughes has observed that nineteenth century inventors made use of the unexpected behaviour of their inventions as sources of novel phenomena to exploit in new inventions. This paper identifies other ways in which Edison made use of failure and proposes that, paradoxically, the success of technological artefacts can be determined by the thoroughness with which failure is pursued in their creation. It also notes a parallel between Edison's instrumentalizing of failure and the way in which recent philosophers of science have proposed that scientists should make use of error. (shrink)

This paper reviews the largely psychological literature surrounding apparent failures of human rationality (sometimes referred to as 'the Rationality Wars') and locates it with respect to concepts and issues within more traditional epistemological inquiry. The goal is to bridge the gap between these two large and typically disconnected literatures – concerning rationality and the psychology of human reasoning, on the one hand, and epistemological theories of justified or rational belief, on the other – and to do so (...) in such as way as to expose interesting points of contact and convergence between them.

This book offers a rigorous, concise, and nontechnical introduction to some of the fundamental insights of rational choice theory. It draws on formal theories of microeconomics, decision making, games, and social choice, and on ideas developed in philosophy, psychology, and sociology. Itzhak Gilboa argues that economic theory has provided a set of powerful models and broad insights that have changed the way we think about everyday life. He focuses on basic insights of the rational choice paradigm--the general conceptualization rather than (...) a particular theory--that survive recent critiques of economic theory's various failures. Gilboa explains the main concepts in language accessible to the nonspecialist, offering a nonmathematical guide to some of the main ideas developed in economic theory in the second half of the twentieth century. Chapters cover feasibility and desirability, utility maximization, constrained optimization, expected utility, probability and statistics, aggregation of preferences, games and equilibria, free markets, and rationality and emotions. Online appendixes offer additional material, including a survey of relevant mathematical concepts. (shrink)

What happens when human beings fail to do as reason bids? This book is an attempt to address this age-old question within Kant’s mature practical philosophy, i.e. the practical philosophy that emerged with the watershed discovery of autonomy in the mid-1780s. As always, Kant is good for a surprise. There is, it is argued, not one answer but two: he advocates Socratic intellectualism in the realm of prudence whilst defending an anti-intellectualist or volitional account of immoral action. This ‘hybrid’ theory (...) of practical failure is more than a philosophical curiosity. There are ramifications for Kant’s theory of practical reason as a whole. In particular, the hybrid account emphasizes the divide between pure and empirical practical rationality to the extent that the latter, while containing practically relevant propositions, no longer counts as a branch of practical reason at all. Hypothetical and categorical imperatives exemplify two entirely distinct kinds of normativity. In fact, the dichotomy between pure and empirical determining grounds of the will goes hand in hand with many other dualisms and dichotomies that, whether we like them or not, continue to define Kant’s mature ethical thought.

This volume of essays is very much a sequel to the two earlier collections by Jon Elster, Ulysses and the Sirens and Sour Grapes. His topic is rationality - its scope, its limitations, and its failures. Elster considers rational responses to the insufficiency of reason itself, and to the 'indeterminacies' in deploying rational-choice theory and discusses the irrationality of not seeing when, where, and what these are. A key essay which gives the collection its title examines disputes in cases (...) of child custody, which are paradigmatically indeterminate. Leaving aside cases where one parent is patently unfit and assuming that protracted dispute is against the immediate interests of the child, Elster argues that three options present themselves: a strong presumption in favour of the mother, a strong presumption in favour of the primary caretaker (also likely to be the mother), and tossing a coin. Though the first two options may be preferable in the short/medium term, Elster argues that there is a case for randomisation in the long term. The book will be read with interest by anyone concerned with political and social science. (shrink)

The first book to address the historical failures of philosophy—and what we can learn from them Philosophers are generally unaware of the failures of philosophy, recognizing only the failures of particular theories, which are then remedied with other theories. But, taking the long view, philosophy has actually collapsed several times, been abandoned, sometimes for centuries, and been replaced by something quite different. When it has been revived it has been with new aims that are often accompanied by implausible attempts to (...) establish continuity with a perennial philosophical tradition. What do these failures tell us? The Failures of Philosophy presents a historical investigation of philosophy in the West, from the perspective of its most significant failures: attempts to provide an account of the good life, to establish philosophy as a discipline that can stand in judgment over other forms of thought, to set up philosophy as a theory of everything, and to construe it as a discipline that rationalizes the empirical and mathematical sciences. Stephen Gaukroger argues that these failures reveal more about philosophical enquiry and its ultimate point than its successes ever could. These failures illustrate how and why philosophical inquiry has been conceived and reconceived, why philosophy has been thought to bring distinctive skills to certain questions, and much more. An important and original account of philosophy’s serial breakdowns, The Failures of Philosophy ultimately shows how these shortcomings paradoxically reveal what matters most about the field.

Kant claims that persons have a perfect duty to respect themselves. I argue, first, that Kant’s argument for the duty of self-respect commits him to an implausible view of the nature of self-respect: he must hold that failures of self-respect are either deliberate or matter of self-deception. I argue, second, that this problem cannot be solved by understanding failures of self-respect as failures of rationality because such a view is incompatible with human psychology. Surely it is not irrational for (...) people, especially members of oppressed groups, to view themselves as having diminished moral worth. (shrink)

In Michael Caie's article “Rational Probabilistic Incoherence,” Caie argues that in light of certain situations involving self-reference, it is sometimes rational to have probabilistically incoherent credences. This essay further considers his arguments. It shows that probabilism isn't to blame for the failure of rational introspection and that Caie's modified accuracy criterion conflicts with Dutch book considerations, is scoring rule dependent, and leads to the failure of rational introspection.

Recent studies indicate that the processing of an unexpected word is costly when the initial, disconfirmed prediction was strong. This penalty was suggested to stem from commitment to the strongly predicted word, requiring its inhibition when disconfirmed. Additional studies show that comprehenders rationally adapt their predictions in different situations. In the current study, we hypothesized that since the disconfirmation of strong predictions incurs costs, it would also trigger adaptation mechanisms influencing the processing of subsequent strong predictions. In two experiments, participants (...) made speeded congruency judgments on two-word phrases in which the first word was either highly constraining or not. We manipulated the proportion of disconfirmed predictions in highly constraining contexts between participants. The results provide additional evidence of the costs associated with the disconfirmation of strong predictions. Moreover, they show a reduction in these costs when participants experience a high proportion of disconfirmed strong predictions throughout the experiment, indicating that participants adjust the strength of their predictions when strong prediction is discouraged. We formulate a Bayesian adaptation model whereby prediction failure cost is weighted by the participant’s belief about the likelihood of encountering the expected word, and show that it accounts for the trial-by-trial data.

Politics, Philosophy & Economics, Volume 21, Issue 2, Page 165-189, May 2022. It is generally acknowledged that a certain amount of state intervention in health and health care is needed to address the significant market failures in these sectors; however, it is also thought that the primary rationale for state involvement in health must lie elsewhere, for example in an egalitarian commitment to equalizing access to health care for all citizens. This paper argues that a complete theory of justice in (...) health can be derived from a commitment to correcting market failure, or in other words promoting Pareto-efficiency, in the domain of health. This approach can address familiar problems around access to care, as well as problems related to resource allocation and rationing, the control of health care costs, and the foundations of public health. Egalitarian theories of justice in health cannot make sense of the depth and pervasiveness of state involvement in health and health care; only a theory rooted in the need to correct market failure can.

This book explores classic philosophical questions regarding the phenomenon of weakness of will or ‘akrasia’: doing A, even though all things considered, you judge it best to do B. Does this phenomenon really exist and if so, how should it be explained? Nacht van Descartes -/- The author provides a historical overview of some traditional answers to these questions and addresses the main question: how does the phenomenon of 'going against your own judgment' relate to the idea that we are (...) rational beings? She elaborates on the notion of rational agency and shows how different types of behaviour express or fail to express our rational agency. This leads to the speculation of what is needed for akratic action to be free action. -/- A novel position is developed, stating that certain widespread philosophical accounts of free action must conclude that 'going against your own judgment' is necessarily unfree. This also requires a reflection on possible implications for moral responsibility. Would it mean that people cannot be held accountable for irrational behaviour? -/- Kalis offers insight on whether everyday irrational behaviour differs from irrational behaviour occurring in the context of psychiatric dysfunction, and develops a view on how we should understand ourselves when we do something other than what we judge best. -/- Written for philosophers, psychologists and psychiatrists interested in issues of irrationality and philosophy of action, this is an indispensable book for both professionals and students interested in interdisciplinary endeavours in the science of mind and behaviour.

The present article addresses the question of whether, and to what extent, critical thinking should make attunement to current social and political landscapes central to its practice. I begin by outlining what I consider to be the basic positions in the debate about the political contextualisation of critical thinking, which are referred to as the crypto-Enlightenment and the critical pedagogical models. I argue, on the basis of various strands of research, that there is a prima facie case to be made (...) in favour of the critical pedagogical position that favours forefronting the social and political context of critical thinking and thinking in general. I then draw attention, however, to problems of coherence and justification in the critical pedagogical position, before turning, finally, to an alternative grounding of critical thinking that takes seriously the historical and social contextualisation of thinking without the coherence problems of critical pedagogy. My conclusion is that while the critical pedagogical model is right to point to the fatal incompleteness of Enlightenment-style critical thinking due to its failure to properly acknowledge the norm-saturated nature of historical consciousness, critical pedagogy itself fails to offer a coherent alternative to the problem of integrating value and rationality in a more full-blown grounding of critical thinking. I suggest that a hermeneutical model that integrates the rational, axiological and historical moments in consciousness provides a more satisfying foundation for understanding the trajectory and purpose of critical thinking.

I argue that the "why be rational?" challenge raised by John Broome and Niko Kolodny rests upon a mistake that is analogous to the mistake that H.A. Pritchard famously claimed beset the “why be moral?” challenge. The failure to locate an independent justification for obeying rational requirements should do nothing whatsoever to undermine our belief in the normativity of rationality. I suggest that we should conceive of the demand for a satisfactory vindicating explanation of the normativity of (...) class='Hi'>rationality instead in terms of the demand for a philosophical characterisation of rationality that can do something to explain why rational requirements are the kinds of things that are, by their very nature, normative. I consider several accounts that have recently been offered – the distinctive-object account, the proper functioning account, and the subjective reasons account – and argue that none succeeds in meeting this challenge. I then sketch a new account, the “first-personal authority account”, which holds that rational requirements are what I call “standpoint-relative demands” concerning the attitudes we ought to have and form; and that complying with rational requirements is a matter of honouring our first-personal authority as agents. I suggest that the first-personal authority account does a better job of meeting the challenge. (shrink)

Habermas has argued that many of the endemic socio- economic problems of Western society are either symptoms or prod ucts of a 'lopsided' process of cultural rationalization, one that has emphasized instrumental forms of rationality over communicative. But other than presenting a rather general typology of lifeworld pathologies, Habermas has not done much to specify what these problems might be, nor has he provided any 'middle-range' analysis of the mechanisms through which they might be generated. This paper discusses some (...) of the ways in which, consistent with Haber mas's general framework, rational choice theory can be used for pre cisely this task. In this analysis, rational choice theory is not presented as a comprehensive theory of action, but is employed as a critical- diagnostic tool that allows the theorist to identify undesirable social interaction patterns that arise from a broader instrumentalization of the lifeworld. Key Words: critical theory • Habermas • instrumental rationality • market failure • rational choice theory. (shrink)

Delusions are explanations of anomalous experiences. A theory of delusion requires an explanation of both the anomalous experience _and _the apparently irrational explanation generated by the delusional subject. Hence, we require a model of rational belief formation against which the belief formation of delusional subjects can be evaluated. _Method. _I first describe such a model, distinguishing procedural from pragmatic rationality. Procedural rationality is the use of rules or procedures, deductive or inductive, that produce an inferentially coherent set of (...) propositions. Pragmatic rationality is the use of procedural rationality _in context_. I then apply the distinction to the explanation of the Capgras and the Cotard delusions. I then argue that delusions are failures of pragmatic rationality. I examine the nature of these failures employing the distinction between performance and competence familiar from Chomskian linguistics. _Results. _This approach to the irrationality of delusions reconciles accounts in which the explanation of the anomalous experience exhausts the explanation of delusion, accounts that appeal to further deficits within the reasoning processes of delusional subjects, and accounts that argue that delusions are not beliefs at all. (Respectively, one-stage, two-stage, and expressive accounts.) _Conclusion. _In paradigm cases that concern cognitive neuropsychiatry the irrationality of delusional subjects should be thought of as a performance deficit in pragmatic rationality.

This book uses the psychological literature on rationality to weigh in on the recent debate between virtue epistemologists and epistemic situationists. It argues that both sides have misconstrued the literature and that an interactionist framework is needed to square epistemic theory with empirical facts about reasoning and inference. The explosion of empirical literature on human rationality has led to seismic shifts across a multitude of academic disciplines. This book considers its implications for epistemology. In particular, it critically evaluates (...) the treatment of the rationality literature within the recent controversy between virtue epistemologists, who attempt to ground knowledge in stable epistemic virtues, and epistemic situationists, who claim that such a project is doomed by empirical evidence of widespread irrationality. It links this foundational controversy to two of the most important debates in psychology: the Rationality Wars and the person-situation debate. The book argues that both virtue theorists and epistemic situationists have misunderstood the implications of these debates, leading them to focus exclusively on personal dispositions and situational factors as two independent sources of epistemic success, failure, and improvement. A more accurate reading of the empirical literature implies that interactions between epistemic agents and their social, informational, and institutional environments are the fundamental drivers of both rational and irrational behaviour. An interactionist framework motivated by this insight conceives of epistemic virtues and vices as both responsive to and responsible for the environments in which they're manifested and cultivated. The central aim of this book is to present and defend this novel type of virtue epistemology. Rationality in Context will be of interest to scholars and advanced students working in epistemology, philosophy of science, philosophy of psychology, cognitive psychology, and social psychology.

ABSTRACT Broome criticizes reasons-responsiveness conceptions of rationality by arguing that while rationality supervenes on non-factive mental states, reasons-responsiveness in the relevant sense does not. I give a limited defence of reasons-responsiveness conceptions of rationality against Broome’s criticisms. I argue that Broome fails to show that reasons-responsiveness conceptions of rationality are barred from regarding non-factive mental duplicates as equally rational in the sorts of ‘New Evil Demon’ scenarios that tend to motivate the intuition that rationality supervenes (...) on non-factive mental states. Still, while reasons-responsiveness conceptions may be able to save our intuitions in such global deception scenarios, I also argue that reasons-responsiveness conceptions have to make surprisingly large concessions in cases of more local deception. Indeed, supervenience failures in local deception cases look rampant. Nonetheless, it is not clear why reasons-responsiveness conceptions should be concerned about this. This is because it is not clear why the idea that rationality supervenes on non-factive mental states should be the kind of non-negotiable starting point for theorizing about rationality that Broome thinks it is. For example, Errol Lord, a recent proponent of a reasons-responsiveness conception of rationality, self-consciously rejects a perfectly general supervenience thesis, regarding it as more important that our conception of rationality satisfies different desiderata: namely, that rationality is normatively significant, and that evaluations of rationality or irrationality imply person-level praise or criticism. Interestingly, Broome regards these latter desiderata as less important, and they are also desiderata that his own conception of rationality has more trouble satisfying. Ultimately, then, disputes between different conceptions of rationality turn in part on disputes concerning which desiderata for a conception of rationality are most important and why. (shrink)

The topic of my dissertation is selfhood. I aim to explain what a self is such that it can sometimes succeed and other times fail at thinking and acting autonomously. I open by considering a failure of autonomy to which I return throughout the dissertation. The failure is that of self-deception. I show that in common cases of self-deception the self-deceived individual fails, due to a motive on his part, to be able to explain the cause of some (...) belief or action of his. There are several philosophical projects that arise when one reflects on this failure. They are presented by the following questions: what are our minds like, such that this failure is possible? For what should we criticize the self-deceived individual, given that he has a motivated lack of self-knowledge but does not know he is so motivated? Is the self-deceived individual epistemically criticizable for lacking explanatory self-knowledge in a way that he is not criticizable for lacking knowledge that would help him explain another's thoughts and actions? By answering these questions I provide an account of the rational unity that goes missing in self-deception and in the related phenomenon of epistemic akrasia. This unity can—and I argue, should—be present in bodily action as well. When a person acts without this unity, he acts in a weak-willed, akratic way. I provide an account of this disunity, which, when added to my account of the disunity of self-deception, reveals the rational unity of an autonomous agent, the rational unity of the self. (shrink)

The overall aim of this thesis is to present a model for rational goal-setting and to illustrate how it can be applied in evaluations of public policies, in particular policies concerning sustainable development and environmental quality. The contents of the thesis are divided into two sections: a theoretical section and an empirical section. Paper I identifies a set of rationality criteria for single goals and discusses them in relation to the typical function of goals. It is argued that goals (...) are typically set to enhance goal achievement. A goal that successfully furthers its achievement is “achievement-inducing”. It holds for each of the identified criteria that, ceteris paribus, improved satisfaction of a criterion makes a goal better in the achievement-inducing sense.Paper II contains an analysis of the notion of goal system coherence. It is argued that the coherence of a goal system is determined by the relations that hold among the goals in the system, in particular the relations of operationalization, means and ends, support, and conflict. Paper III investigates the rationality of utopian goals. The paper analyzes four arguments that support the normative criterion of attainability: that utopian goals are too imprecise and too far-reaching to guide action effectively, counterproductive, and morally objectionable. A tentative defence of utopian goal-setting is built on counter-arguments that can be put forward to weaken each of the four objections. Paper IV investigates the nature of self-defeating goals. The paper identifies three types of situations in which self-defeating mechanisms obstruct goal achievement: situations in which the goal itself carries the seeds of its own non-fulfilment, situations in which the activity of goal-setting contributes to goal failure, and situations in which disclosure of the goal interferes with progress. Paper V provides a brief description of the Swedish system of environmental objectives and a preliminary inventory of the management difficulties that attach to this goal system.Paper VI contains an investigation into the rationality of five Swedish environmental objectives through an application of the rationality criteria identified in Papers I-II. The paper identifies and discusses some difficulties that are associated with management by objectives and the use of goals in environmental policy. Paper VII analyses the rationality of the Swedish environmental quality objective A good built environment. Among the conclusions drawn in the paper are that some of the sub-goals to the objective are formulated in terms that are unnecessarily vague from an action-guiding standpoint and that others are problematic from the viewpoint of evaluability.

It is standard, both in the philosophical literature and in ordinary parlance, to assume that one can fall short of responding to all one’s moral reasons without being irrational. Yet when we turn to epistemic reasons, the situation could not be more different. Most epistemologists take it as axiomatic that for a belief to be rational is for it to be well-supported by epistemic reasons. We find ourselves with a striking asymmetry, then, between the moral and epistemic domains concerning what (...) is taken for granted about whether failures to respond to reasons are failures of rationality. My aim in this paper is to interrogate this asymmetry, and ultimately to argue that the asymmetry is groundless. Instead, I will offer an error theory to explain the asymmetry in intuitions. This error theory suggests that we should amend the conventional wisdom about the relationship between epistemic reasons and rationality. (shrink)

In the following we study the evolution of support networks among egoists who differ widely in their degree of neediness, are free to choose their partners, and do so in opportunistic ways. No central authority is involved. The question we address is to what degree and under what aspect it shapes the structure of emerging solidarity networks whether we model egoistic actors as rational actors in a game theoretical sense or as adaptive actors, i.e. learning beings following a simple learning (...) mechanism which is driven by success and failure.1 The central modelling ideas to address that question are: Support relationships are modelled by a 2-person support game. The social space in which a network can emerge is a 2-dimensional cellular grid. Actors can play the support game simultaneously with all their neighbours. Not all cells are occupied. From time to time players have the opportunities to migrate. In one model we make our actors rational beings, in a second one we make them adaptive agents. Obviously we use a cellular automata framework of modelling . Especially because of its simplicity that framework has often proved fruitful for analysing micro/macro relations. (shrink)

When the Parrondo effect was discovered a few years ago (Harmer and Abbott 1999a, 1999b), it was hailed as a possible mechanism whereby, in a kind of collaboration of failure, losing strategies could be combined to yield profit. The precise relevance of the Parrondo effect to natural and social phenomena is however still unclear. In this paper we give specific examples, first in the artificial setting of a gambling machine, and then in more natural applications to genetics and to (...) environmental policies. This last example touches questions of rational behaviour and expected utility in a novel setting. (shrink)
