In their recent book, Epistemology and the Psychology of Human Judgment, Michael Bishop and J.D. Trout have challenged Standard Analytic Epistemology (SAE) in all its guises and have endorsed a version of the "replacement thesis"--proponents of which aim at replacing the standard questions of SAE with psychological questions. In this article I argue that Bishop and Trout offer an incomplete epistemology that, as formulated, cannot address many of the core issues that motivate interest in epistemological questions to begin with, and (...) so is not a fit replacement.

In the last two decades, the greatest threat to armchair philosophy has been the natural kinds approach. On this view, philosophic theorizing should not be obsessed with the ideas of justice, goodness, and truth but should look outward to the world of objects to find these things. And if these things happen to be natural kinds, like kinds of rock or fish for instance, then clearly we should reject the armchair for the lab. The philosopher should leave the office and (...) join the scientist out in the field. Philosophy should become a species of science. We attempt to defend traditional/armchair philosophy by examining Hilary Kornblith’s naturalistic methodological approach to epistemology. Among other things, we argue that Kornblith’s approach leads to some surprising, undesirable results (at least undesirable to the naturalist), one of which is that Kornblith cannot discount epistemic internalism as a viable contender in the search for the nature of knowledge. His methodology actually requires that we take epistemic internalism seriously. (shrink)

Dans cette contribution, j’examine la spécificité d’une perspective d’épistémologie sociale en théorie de l’argumentation en me livrant à une analyse critique de la théorie actuellement dominante dans ce champ, la pragma-dialectique de Franz van Eemeren. Cette perspective, d’inspiration interactionniste gricéenne, se réclame du « rationalisme critique », donc d’une perspective épistémologiquement « préservationniste » (au sens où elle préserverait l’idée de référence à des normes de la connaissance). Et pourtant, en faisant des normes du débat argumenté, y compris des normes (...) de la connaissance, de simples règles de « bonne conduite », elle témoigne, de facto, d’une position épistémologiquement « révisionniste ». Cette perspective manifeste, par ailleurs, une forme d’« expansionnisme » sociologique élémentaire, comme tel légitime si l’on considère qu’introduire deux sujets, c’est déjà introduire du social. La pragma-dialectique n’introduit pas de nouveaux sujets de connaissance sui generis, tels que les communautés épistémiques ou les institutions (ce qui serait pour Alvin Goldman le critère de l’expansionnisme, un critère à mon sens trop fort), mais comme il s’agit de rendre compte d’argumentations, elle doit envisager au moins deux interlocuteurs potentiels et donc dépasser le solipsisme épistémologique, une posture explicite chez Descartes et implicite dans la plupart des théories de la connaissance classiques, lesquelles font rarement réellement place à l’intersubjectivité. Malgré ses limites, la pragma-dialectique, par sa recherche de normes de la construction de la connaissance plus proches des processus effectifs ou naturels de la connaissance, pourrait constituer – épistémologiquement redressée – une contribution importante à une épistémologie sociale « naturalisée ».

In this article I ask whether elaborated and systematized delusions emerging in the context of schizophrenia have the potential for epistemic innocence. Cognitions are epistemically innocent if they have significant epistemic benefits that could not be attained otherwise. In particular, I propose that a cognition is epistemically innocent if it delivers some significant epistemic benefit to a given agent at a given time, and if alternative cognitions delivering the same epistemic benefit are unavailable to that agent at that time. Elaborated (...) and systematized delusions in schizophrenia are typically false and exemplify failures of rationality and self-knowledge. Empirical studies suggest that they may have psychological benefits by relieving anxiety and enhancing meaningfulness. Moreover, these delusions have been considered as adaptive in virtue of the fact that they enable automated learning to resume after a significant disruption caused by incorrect prediction-error signalling. I argue that such psychological benefits and adaptive features also have positive epistemic consequences. More precisely, delusions can be a means to restoring epistemic functionality in agents who are overwhelmed by hypersalient experiences in the prodromal stage of psychosis. The analysis leads to a more complex view of the epistemic status of delusions than is found in the contemporary philosophical literature and has some implications for clinical practice. 1 Introduction2 Types of Delusions3 What Is Wrong with Elaborated and Systematized Delusions?4 Finding Life Meaningful5 Learning Resumed6 Epistemic Innocence7 Epistemic Benefit8 No Alternatives9 Conclusions and Implications.

One feature of vague predicates is that, as far as appearances go, they lack sharp application boundaries. I argue that we would not be able to locate boundaries even if vague predicates had sharp boundaries. I do so by developing an idealized cognitive model of a categorization faculty which has mobile and dynamic sortals (`classes', `concepts' or `categories') and formally prove that the degree of precision with which boundaries of such sortals can be located is inversely constrained by their flexibility. (...) Given the literature, it is plausible that we are appropriately like the model. Hence, an inability to locate sharp boundaries is not necessarily because there are none; boundaries could be sharp and it is plausible that we would nevertheless be unable to locate them. (shrink)

In The Uses of Argument, Stephen Toulmin proposed a model for the layout of arguments: claim, data, warrant, qualifier, rebuttal, backing. Since then, Toulmin’s model has been appropriated, adapted and extended by researchers in speech communications, philosophy and artificial intelligence. This book assembles the best contemporary reflection in these fields, extending or challenging Toulmin’s ideas in ways that make fresh contributions to the theory of analysing and evaluating arguments.

This paper develops a means–end analysis of an inductive problem that arises in particle physics: how to infer from observed reactions conservation principles that govern all reactions among elementary particles. I show that there is a reliable inference procedure that is guaranteed to arrive at an empirically adequate set of conservation principles as more and more evidence is obtained. An interesting feature of reliable procedures for finding conservation principles is that in certain precisely defined circumstances they must introduce hidden particles. (...) Among the reliable inductive methods there is a unique procedure that minimizes convergence time as well as the number of times that the method revises its conservation principles. Thus the aims of reliable, fast and steady convergence to an empirically adequate theory single out a unique optimal inference for a given set of observed reactions—including prescriptions for when exactly to introduce hidden particles.

To identify and conceptualize research problems in science, philosophers and often scientists rely on classical accounts of problems that focus on intellectual problems defined in relation to theories. Recently, philosophers have begun to study the structures and functions of research problems not defined in relation to theories. Furthermore, scientists have long pursued research problems often labeled as practical or applied. As yet, no account of problems specifies the description of both so-called intellectual problems and so-called applied problems. This article proposes (...) a new conceptual framework of problems that accounts both for intellectual aspects of problems and for their practical or applied aspects. I illustrate the account with an example of a recent research project from evolutionary biology, and I indicate further routes by that to develop the account, especially in connection to empirical studies of science.
