Epistemic systems are social processes generating judgments of truth and falsity. I outline a mathematical theory of epistemic systems that applies widely. Areas of application include pure science, torture, police forensics, espionage, auditing, clinical medical testing, democratic procedure, and the market economy. I examine torture and police forensics in relative detail. This paper is an exercise in comparative institutional epistemics, which considers how the institutions of an epistemic system influence its performance as measured by such things as error rates and (...) the volume of judgments generated.

The American criminal justice system creates incentives for false conviction. For example, many public crime labs are funded in part per conviction. We show that the number of false convictions per year in the American criminal justice system should be considered ?high.? We examine the incentives of police, forensic scientists, prosecutors, and public defenders in the U.S. Police, prosecutors, and forensic scientists often have an incentive to garner convictions with little incentive to convict the right person. These incentives create what (...) economists call a ?multitask problem? that seems to be resulting in a needlessly high rate of false convictions. Public defenders lack the resources and incentives needed to provide a vigorous defense for their clients. Corrective measures are discussed, along with a call for more research. (shrink)

Forensic science error rates are needlessly high. Applying the perspective of veritistic social epistemology to forensic science could produce new institutional designs that would lower forensic error rates. We make such an application through experiments in the laboratory with human subjects. Redundancy is the key to error prevention, discovery, and elimination. In the “monopoly epistemics” characterizing forensics today, one privileged actor is asked to identify the truth. In “democratic epistemics,” several independent parties are asked. In an experiment contrasting them, democratic (...) epistemics reduced the rate at which biased observers obscured the truth by two-thirds. These results highlight, first, the potential of “epistemic systems design,” which employs the techniques of economic systems design to address issues of veracity rather than efficiency, and second, the value of “experimental epistemology,” which employs experimental techniques in the study of science.

L’activité entrepreneuriale génère l’activité entrepreneuriale. Cet article développe cette idée dans une perspective autrichienne. Nous envisageons les entrepreneurs kirznériens sous l’angle de l’apprentissage hayékien. L’activité entrepreneuriale développe l’activité entrepreneuriale de deux manières. Premièrement, la mise en oeuvre d’une nouvelle tentative crée de nouvelles opportunités pour d’autres nouvelles tentatives. Deuxièmement, chaque acte entrepreneurial kirznérien est un exemple incitant les autres à faire de même. Nous mettons l’accent sur le second point.

This insight is developed within the context of Austrian economics. We view Kirznerian entrepreneurs as Hayekian learners. Entrepreneurship breeds entrepreneurship two ways. First, the founding of a new venture creates new opportunities for other new ventures. Second, each act of Kirznerian entrepreneurship is a favorable example for others to follow. We concentrate on the second point. Each act of newventure entrepreneurship changes the perceptions of others about how new ventures are founded, what sort of person might do it, and so on. It makes people more alert. Thus, entrepreneurship creates a network externality. This externality explains the fact that otherwise similar communities produce dissimilar levels of new-venture entrepreneurship. (shrink)

Israel Kirzner’s concept of “alertness” is recast in the language of phenomenological psychology. Our ideas about things are either openended ideas posing no particular problem of choice, “open possibilities”, or alternatives to choose between, “problematic possibilities”. Choice is the process of formulating problematic possibilities; it is the process of reinterpreting one’s situation. The fully formed reinterpretation generates the chosen outcome as a necessary consequence of preferences and perceived constraints. Reinterpretation precedes choice, both logically and temporally. This understanding of alertness helps (...) to clarify Austrian ideas such as the idea that preferences do not exist apart from action.Le concept de “vigilance” d’Israel Kirzner est reformulé dans le langage de la psychologie phéno- ménologique. Nos idées à propos des choses sont souvent des idées à finalité ouverte ne soulevant pas de problème particulier de choix, “des possibilités ouvertes”, ou des alternatives de choix entre des “possibilités problématiques”. Le choix est un processus de formulation de possibilités problématiques ; c’est le processus consistant à réinterpréter nos propres situations. Dans sa formulation ultime, la réinterprétation génère le résultat choisi comme conséquence nécessaire des préférences et des contraintes perçues. La réinterprétation précède le choix, et logiquement et temporellement. Cette compréhension de la vigilance aide à clarifier les idées Autrichiennes telle que l’idée selon laquelle les préférences n’existent pas indépendamment de l’action. (shrink)

I argue that its appearing to you that P does not provide justification for believing that P unless you have independent justification for the denial of skeptical alternatives – hypotheses incompatible with P but such that if they were true, it would still appear to you that P. Thus I challenge the popular view of ‘dogmatism,’ according to which for some contents P, you need only lack reason to suspect that skeptical alternatives are true, in order for an experience as (...) of P to justify belief that P. I pursue three lines of objection to dogmatism, having to do with probabilistic reasoning, considerations of future or hypothetically available justification, and epistemic circularity. I briefly sketch a fall-back position which avoids the problems raised. (shrink)

Michael Bergmann claims that all versions of epistemic internalism face an irresolvable dilemma. We show that there are many plausible versions of internalism that falsify this claim. First, we demonstrate that there are versions of ‘‘weak awareness internalism’’ that, contra Bergmann, do not succumb to the ‘‘Subject’s Perspective Objection’’ horn of the dilemma. Second, we show that there are versions of ‘‘strong awareness internalism’’ that do not fall prey to the dilemma’s ‘‘vicious regress’’ horn. We note along the way that (...) these versions of internalism do not, in avoiding one horn of the dilemma, succumb to the dilemma’s other horn. The upshot is that internalists have many available strategies for avoiding dilemmatic defeat. (shrink)

I believe that Tom is the proud father of a baby boy. Why do I think his child is a boy? A natural answer might be that I remember that his name is ‘Owen’ which is usually a boy’s name. Here I’ve given information that might be part of a causal explanation of my believing that Tom’s baby is a boy. I do have such a memory and it is largely what sustains my conviction. But I haven’t given you just (...) any causally relevant information, I’ve given my grounds for my belief. I’ve given reasons that might justify me in supposing that Tom’s baby is a boy. Less naturally, the question might be taken as a request for a broader causal explanation of my holding this belief. Appropriate answers might cite all manner of facts concerning the evolution of the human race, why I chose to pursue philosophy and hence came to know Tom, the mechanisms of email transmission, the firing of various neurons, the circumstances of concept formation as a result of which I’m able to grasp the thought that Tom’s baby is a boy, and so on. It is an interesting question what distinguishes the narrower set of answers that I first suggested. I won’t pursue that here. I assume you have a good enough sense of the distinction I’m drawing. We might call the narrower set of answers justifying reasons, the kind of reasons I might cite in justifying my belief. Answers of the first sort are clearly relevant to epistemological evaluation. In assessing whether you know p or are rational in believing it to the degree you do, I will naturally want to consider what reasons you have for your belief. In deliberating myself about whether to believe p, in seeking an answer to the question of whether p, I will naturally consider what reasons or grounds I have to suppose that p. But what I want to focus on here is how explanations of the broader sort bear on such questions as whether to believe p. From a third-person perspective we can ask, ‘In assessing the epistemic status of S’s belief that p, what is the relevance of causal information that lies outside of the realm of justifying reasons?’ From the first-person standpoint we can ask ‘In seeking to answer whether p, how should such causal information affect my deliberations?’ At first it might seem that such broader causal information could have little relevance if any. Like any belief my belief that p can be traced back to innumerable causes from far and wide.. (shrink)

This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects on the (...) compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

The preface paradox does not show that it can be rational to have inconsistent beliefs, because preface writers do not have inconsistent beliefs. I argue, first, that a fully satisfactory solution to the preface paradox would have it that the preface writer's beliefs are consistent. The case here is on basic intuitive grounds, not the consequence of a theory of rationality or of belief. Second, I point out that there is an independently motivated theory of belief – sensitivism – which (...) allows such a solution. I sketch a sensitivist account of the preface writer's doxastic state. (shrink)

Confidentiality of health information is increasingly relevant in the era of electronic medical records. We discuss the case of a hospitalized patient who requested a neurology consultation for an episode he described as an “LSD-like” flashback. The patient expressed concern that the episode was a residual effect of past drug use, but subsequently requested that his drug use not be documented. Involved in a custody battle, he feared that if his records were released to the court he could lose custody (...) of his children. Ethical concerns arose with regards to the physician’s competing obligations with a duty to record information accurately and honestly, respect patient autonomy, and maintain patient confidentiality. We discuss the decision of the team to document the patient’s drug use by arguing that the obligation to maintain confidentiality did not supersede the primary role of the medical record as a complete and accurate account, which cannot be altered at a patient’s behest.

My intention is to show that, starting from an empiricist philosophy of mind, it is possible to give a systematic account of aesthetic experience. I argue that empiricism involves a certain theory of meaning and truth; one problem is to show how this theory is compatible with the activity of aesthetic judgment. I investigate and reject two attempts to delimit the realm of the aesthetic: one in terms of the individuality of the aesthetic object, and the other in terms of (...) 'aesthetic properties'. I go on to argue that aesthetic descriptions must not be thought to ascribe properties to their objects, and I show how the suggestion that they are non-descriptive need not conflict with the empiricist view of meaning. The problem is then seen to lie with the analysis of the 'acceptance-conditions' of aesthetic descriptions. I counter certain idealist objections to this approach, and then present a theory of imagination, in terms of which the acceptance conditions of aesthetic judgments may be described. This theory attempts to explain how the element of thought in aesthetic appreciation may become inseparable from an experience of its object, and how the aesthetic emotions are both like and unlike their equivalents in life. The first part concludes with an analysis of the general conditions of aesthetic experience. I try to show that aesthetic experience can be described in terms of certain 'formal' properties, independently of its material object. In the second part I am concerned to show that this empiricist theory of aesthetics does not, like most empiricist theories, make nonsense of our appreciation of art. First, I attempt to show that 'understanding' art is not merely a cognitive process, but involves certain experiences that can be accounted for in terms of the previous theory. I then analyse the concepts of representation and expression, and in the course of this analysis I attempt to refute what I take to be the most serious rival analysis of our appreciation of art - the semantic theory.

Abstract Scientific advances have made the end of life into the primary concern of medicine. But medicine also postpones the end of life, often until the time when we no longer have the mental and physical capacity to deal with it. I argue that we need to develop Nietzsche's idea of timely death, in order to find a moral basis for health care at the end of life, and that the crucial factor is the cultivation of the virtues that would (...) enable us to live in another and more reckless way. We should look on the problem not from the first-person point of view, but from the perspective of the other, and ask ourselves what is most admirable in another person, in his or her attitude to death. The point of timely death is to make death into the completion of life, where life is understood as a moral rather than a biological idea. (shrink)

Gödel appears to have believed strongly that the human mind cannot be explained in terms of any kind of computational physics, but he remained cautious in formulating this belief as a rigorous consequence of his incompleteness theorems. In this chapter, I discuss a modification of standard Gödel-type logical arguments, these appearing to strengthen Gödel’s conclusions, and attempt to provide a persuasive case in support of his standpoint that the actions of the mind must transcend computation. It appears that Gödel did (...) not consider the possibility that the laws of physics might themselves involve noncomputational procedures; accordingly, he found himself driven to the conclusion that mentality must lie beyond the actions of the physical brain. My own arguments, on the other hand, are from the scientific standpoint that the mind is a product of the brain’s physical activity. Accordingly, there must be something in the physical actions of the world that itself transcends computation. We do not appear to find such noncomputational action in the known laws of physics, however, so we must seek it in currently undiscovered laws going beyond presently accepted physical theory. I argue that the only plausibly relevant gap in current understanding lies in a fundamental incompleteness in quantum theory, which reveals itself only with significant mass displacements between quantum states (“Schrödinger’s cats”). I contend that the need for new physics enters when gravitational effects just begin to play a role. In a scheme developed jointly with Stuart Hameroff, this has direct relevance within neuronal microtubules, and I describe this (still speculative) scheme in the following. (shrink)

A-t-on le droit de croire en l'existence de Dieu? Non, répondent ceux qui veulent des preuves. Oui, affirme ce livre, car nous avons le droit de croire même sans justification épistémologique. Cela n'a rien d'intellectuellement honteux, contrairement à ce que disent certains philosophes, en parlant d'une éthique des croyances Une nouvelle question se pose alors : a-t-on le droit de croire avoir reçu une révélation et prétendre connaître ainsi la vérité? Non, répondent ceux pour lesquels la vérité ne peut pas (...) être donnée par Dieu dans la Bible. Oui, affirme ce livre, et, qui plus est, une épistémologie peut défendre la rationalité de notre croyance à la révélation. Dès lors, peut-on faire comme si les affirmations du Credo étaient des fictions? Est-il vrai que la religion est avant tout une affaire pratique et une forme de vie? Non, répond ce livre : les arguments en faveur d'une conception non réaliste de la religion sont faibles ; en revanche, le réalisme théologique peut être défendu. Renouvelant ainsi la traditionnelle question de la relation entre foi et raison, ce livre discute aussi bien les thèses de saint Thomas, de John Locke, du cardinal Newman et de Ludwig Wittgenstein, que celles de philosophes analytiques contemporains de la religion comme Alvin Plantinga, Richard Swinburne, Peter van Inwagen ou Linda Zagzebski.

Sexual experimentation, living together, raising children outside of marriage, remarriage after divorce, and same-sex relationships...These behaviours have become common in the wider society as well as among Christians and Catholic Christians. Not only do they think and act differently than the official Church teaching, but they do so convinced that they are acting rightly. This challenges ethics to respond by what can be called an 'ethics of mercy', by meeting people where they are and helping them to grow towards the (...) fullness of life and love. Such a pastoral and educational ethics of growth should dare to stand within the tension between what is desirable and what is attainable, without surrendering the 'pro-vocative' idea of conjugal covenant as the basis for the family. Mercy is needed not only after ethics but in ethics. In harmony with Pope Francis's plea for a 'gospel of mercy', this book seeks a middle way between merciless rigourism and relativising subjectivism. It proposes an ethics of redemption that accompanies people on their way to meaningful living and loving, grounded in a spirituality that springs from the salvation offered in Jesus. (shrink)

This paper seeks critically to elucidate Hume’s views on pleasure and the good, in particular his evaluative hedonism, and to show that evaluative hedonism is in certain respects at least as significant a component of his philosophical ethics as sentimentalism. The first section explains his notion of pleasure, and how it is, in an important sense, prior to desire. The following two sections show how this conception of pleasure and its relation to desire leads Hume to accept evaluative hedonism, as (...) well as a form of psychological hedonism, and to give pleasure a key role in his metaethics. The paper ends, as do both the Treatise and the second Enquiry, with the distinction—a false one, according to Hume—between virtues and natural abilities, and an attempt to bring out the implicit challenge Hume is making to non-hedonist accounts of value, especially those that postulate “moral” value.
