In standard decision theory, the probability function ought to be updated in light of evidence, but the utility function generally stays fixed. However, there is nothing in the formal theory that prevents one from instead updating the utility function, while keeping the probability function fixed. Moreover, there are good arguments for updating the utilities and not just the probabilities. Hence, the first puzzle is whether there is anything that justifies updating beliefs, but not desires, in light of evidence. The paper (...) argues that there is not, but that this raises a second puzzle. (shrink)

Bayesian inference is limited in scope because it cannot be applied in idealized contexts where none of the hypotheses under consideration is true and because it is committed to always using the likelihood as a measure of evidential favouring, even when that is inappropriate. The purpose of this article is to study inductive inference in a very general setting where finding the truth is not necessarily the goal and where the measure of evidential favouring is not necessarily the likelihood. I (...) use an accuracy argument to argue for probabilism and I develop a new kind of argument to argue for two general updating rules, both of which are reasonable in different contexts. One of the updating rules has standard Bayesian updating, Bissiri et al.’s general Bayesian updating, Douven’s IBE-based updating, and Vassend’s ]) quasi-Bayesian updating as special cases. The other updating rule is novel. (shrink)

The aim of this paper is to diagnose the so-called two envelopes paradox. Many writers have claimed that there is something genuinely paradoxical in the situation with the two envelopes, and some writers are now developing non-standards theories of expected utility. I claim that there is no paradox for expected utility theory as I understand that theory, and that contrary claims are confused. Expected utility theory is completely unaffected by the two-envelope paradox.

The article discusses relationships and contexts for "reason", "knowledge", and virtue in Aristotle, based on and elaborating some results from Eikeland. It positions Eikeland in relation to Moss but with a side view to Cammick, Kristjansson, and Taylor. These all seem to disagree among themselves but still agree partly in different ways with Eikeland. The text focuses on two questions: 1) the role or tasks of "reason", "knowledge", and "virtue" respectively in setting the end or goal for ethical deliberation, and (...) more generally, 2) the role of dialogue or dialectics in Aristotle's philosophy, including its role concerning question one. The author argues that phrónêsis needs to be interpreted in the context of the totality of Aristotle's philosophy, and explains how this totality is fundamentally dialectical. (shrink)

The Y chromosomes of most Drosophila species are necessary for male fertility but they are not involved in sex determination. They have many puzzling properties that resemble the effects caused by B chromosomes. Classical genetic and molecular studies reveal substantial affinities between Y and B chromosomes and suggest that the Y chromosomes of Drosophila are not degenerated homologues of the X chromosomes, but rather that their Y chromosomes evolved as specialized supernumeraries similar to classical B chromosomes.

Myths of the Self is a departure from the standard fare of postmodern thought. In a unique and brilliant turn, Smith argues that the best way of dealing with the topic of the self is a synthesis of a narrative theory of identity, using Ricoeur as a source, along with the constructive "postmodern" metaphysics of Alfred North Whitehead. The resulting synthesis is a new and potentially invigorating spin on the genesis of postmodern thought.

Scientists and Bayesian statisticians often study hypotheses that they know to be false. This creates an interpretive problem because the Bayesian probability of a hypothesis is supposed to represent the probability that the hypothesis is true. I investigate whether Bayesianism can accommodate the idea that false hypotheses are sometimes approximately true or that some hypotheses or models can be closer to the truth than others. I argue that the idea that some hypotheses are approximately true in an absolute sense is (...) hard to square with Bayesianism, but that the notion that some hypotheses are comparatively closer to the truth than others can be made compatible with Bayesianism, and that this provides an adequate and potentially useful solution to the interpretive problem. Finally, I compare my ``verisimilitude'' solution to the interpretive problem with a ``counterfactual'' solution recently proposed by Jan Sprenger. (shrink)

According to a widespread but implicit thesis in Bayesian confirmation theory, two confirmation measures are considered equivalent if they are ordinally equivalent—call this the “ordinal equivalence thesis”. I argue that adopting OET has significant costs. First, adopting OET renders one incapable of determining whether a piece of evidence substantially favors one hypothesis over another. Second, OET must be rejected if merely ordinal conclusions are to be drawn from the expected value of a confirmation measure. Furthermore, several arguments and applications of (...) confirmation measures given in the literature already rely on a rejection of OET. I also contrast OET with stronger equivalence theses and show that they do not have the same costs as OET. On the other hand, adopting a thesis stronger than OET has costs of its own, since a rejection of OET ostensibly implies that people’s epistemic states have a very fine-grained quantitative structure. However, I suggest that the normative upshot of the paper in fact has a conditional form, and that other Bayesian norms can also fruitfully be construed as having a similar conditional form.

Charles Stein discovered a paradox in 1955 that many statisticians think is of fundamental importance. Here we explore its philosophical implications. We outline the nature of Stein’s result and of subsequent work on shrinkage estimators; then we describe how these results are related to Bayesianism and to model selection criteria like AIC. We also discuss their bearing on scientific realism and instrumentalism. We argue that results concerning shrinkage estimators underwrite a surprising form of holistic pragmatism.

Aunque el modelo de atención en salud ha evolucionado, aún suele desplazar la importancia de incluir la narrativa del paciente e intenta uniformar las necesidades de las personas enfermas. La medicina narrativa nos da la capacidad de interpretar y comunicar los relatos de nuestros pacientes, a través de la escucha activa, así como de valorar la complejidad del ser humano, a diferencia de la salud basada en la evidencia, donde las experiencias de un individuo son extrapolables a otros pacientes sin (...) importar su historia, con lo que se reduce gran parte de la narración a una clasificación objetiva en la ficha clínica, cuando lo correcto sería integrar el paradigma narrativo en la atención de personas enfermas. Creemos que enseñar competencias narrativas y saber científico a profesionales de odontología permitirá estrechar la relación clínica con los pacientes a partir de valores como la empatía y la compasión, mermando el sufrimiento ligado a lo objetivo de sus enfermedades.

Scientists often study hypotheses that they know to be false. This creates an interpretive problem for Bayesians because the probability assigned to a hypothesis is typically interpreted as the probability that the hypothesis is true. I argue that solving the interpretive problem requires coming up with a new semantics for Bayesian inference. I present and contrast two new semantic frameworks, and I argue that both of them support the claim that there is pervasive pragmatic encroachment on whether a given Bayesian (...) probability assignment is rational.

The original article, which first appeared in Norwegian, is a detailed study of anamnesis or recollection in Plato and Aristotle. It discusses, first, how recollection is relevant for the understanding of central aspects of the philosophy of Aristotle, and then discusses how the “regained” Platonic-Aristotelian concept of anamnesis can be related to current methodological challenges in modern social research. After having received feedback on the original article from David Bloch, who has recently translated and commented the Aristotelian text “On memory (...) and recollection”, I have decided to rewrite it in English and publish it here.

Bayesianism and likelihoodism are two of the most important frameworks philosophers of science use to analyse scientific methodology. However, both frameworks face a serious objection: much scientific inquiry takes place in highly idealized frameworks where all the hypotheses are known to be false. Yet, both Bayesianism and likelihoodism seem to be based on the assumption that the goal of scientific inquiry is always truth rather than closeness to the truth. Here, I argue in favour of a verisimilitude framework for inductive (...) inference. In the verisimilitude framework, scientific inquiry is conceived of, in part, as a process where inference methods ought to be calibrated to appropriate measures of closeness to the truth. To illustrate the verisimilitude framework, I offer a reconstruction of parsimony evaluations of scientific theories, and I give a reconstruction and extended analysis of the use of parsimony inference in phylogenetics. By recasting phylogenetic inference in the verisimilitude framework, it becomes possible to both raise and address objections to phylogenetic methods that rely on parsimony. 1Introduction2Problems with the Law of Likelihood3Introducing Verisimilitude-Based Inference4Examples of Verisimilitude-Based Inference Procedures4.1Parsimony inference over theories4.2Parsimony inference in phylogenetics5Conclusion.

Cappelen and Dever have recently defended the view that indexicals are not essential: They do not signify anything philosophically deep and we do not need indexicals for any important philosophical work. This paper contests their view from the point of view of an account of intentional agency. It argues that we need indexicals essentially when accounting for what it is do something intentionally and, as a consequence, intentional action, and defends a view of intentional action as a possible conclusion of (...) practical reasoning where the indexical is essential for the content of such a conclusion.

It is often thought that the main significant difference between evidential decision theory and causal decision theory is that they recommend different acts in Newcomb-style examples (broadly construed) where acts and states are correlated in peculiar ways. However, this paper presents a class of non-Newcombian examples that evidential decision theory cannot adequately model whereas causal decision theory can. Briefly, the examples involve situations where it is clearly best to perform an act that will not influence the desired outcome. On evidential (...) decision theory—but not causal decision theory—this situation turns out to be impossible: acts that an agent does not think influence the desired outcome are never optimal. Typically, sophisticated versions of evidential decision theory emulate causal decision theoretic reasoning by (implicitly) conditioning on causal confounders, but in the kind of example considered here, this trick does not work. The upshot is that there is more to causal reasoning than has so far been appreciated. (shrink)

In his target article and recent interesting book about addiction and the brain, Marc Lewis claims that the prevalent medical view of addiction as a brain disease or a disorder, is mistaken. In this commentary we critically examine his arguments for this claim. We find these arguments to rest on some problematical and largely undefended assumptions about notions of disease, disorder and the demarcation between them and good health. Even if addiction does seem to differ from some typical brain diseases, (...) we believe contrary to Lewis, that there are still good reasons to maintain its classification as a mental or behavioral disorder.

David Hunter has recently argued that Donald Davidson and Elizabeth Anscombe were in basic agreement about practical knowledge. In this reply, it is my contention that Hunter’s fascinating claim may not be satisfactorily warranted. To throw light on why, a more careful consideration of the role of the notion of practical knowledge in Anscombe’s approach to intentional action is undertaken. The result indicates a possible need to distinguish between what is called ‘practical knowledge’ and ‘ knowledge of what one is (...) doing’, and shows that Hunter’s claim concerning the closeness of Anscombe to Davidson only has plausibility for knowledge of what one is doing. Contrary to an interesting suggestion by Hunter, the paper argues that it is hard to see how Davidson’s position can benefit substantially from making use of the notion of knowledge of what one is doing.

This volume comprises systematic as well as historical essays, including contributions intended to give comprehensive overviews of such areas as genetic phenomenology, transcendental phenomenology, philosophy and history of logic and mathematics, Kant, hermeneutics, Hegel, and philosophy of language. The book is addressed to phenomenologists, particularly those who are interested in some or all of the areas mentioned. In his introduction Joseph J. Kockelmans indicates that these diverse areas enter into dialogue in the work of Thomas M. Seebohm, whom the editors (...) and authors wish to honor, and the systematic papers mirror the state of the art of research in the above-mentioned disciplines. (shrink)

Stanley Stevens draws a useful distinction among ordinal scales, interval scales, and ratio scales. Most recent discussions of confirmation measures have proceeded on the ordinal level of analysis. In this article, I give a more quantitative analysis. In particular, I show that the requirement that our desired confirmation measure be at least an interval measure naturally yields necessary conditions that jointly entail the log-likelihood measure. Thus, I conclude that the log-likelihood measure is the only good candidate interval measure.
