The epistemically virtuous clinician

Today, modern Western medicine is facing a quality-of-care crisis that is undermining the patient–physician relationship. In this paper, a notion of the epistemically virtuous clinician is proposed in terms of both the reliabilist and responsibilist versions of virtue epistemology, in order to help address this crisis. To that end, a clinical case study from the literature is first reconstructed. The reliabilist intellectual virtues, including the perceptual and conceptual virtues, are then discussed and applied to the case study. Next, a similar method is employed to examine the responsibilist intellectual virtues, including curiosity, courage, honesty, and humility, and to apply them to the case study. To round out the discussion, the love of knowledge and both theoretical and practical wisdom are explored and applied to the case study. The paper concludes with a brief discussion of how the notion of an epistemically virtuous clinician addresses the quality-of-care crisis, in terms of the connection between ethical and intellectual virtues, and of the notion’s implications for medical education.

Preschoolers trust novel members of accurate speakers' groups and judge them favourably

By age 3, children track a speaker's record of past accuracy and use it as a cue to current reliability. Two experiments (N?=?95 children) explored whether preschoolers' judgements about, and trust in, the accuracy of a previously reliable informant extend to other members of the informant's group. In Experiment 1, both 3- and 4-year-olds consistently judged an animated character who was associated with a previously accurate speaker more likely to be correct than a character associated with a previously inaccurate speaker, despite possessing no information about these characters' individual records of reliability. They continued to show this preference one week later. Experiment 2 presented 4- and 5-year-olds with a related task using videos of human actors. Both showed preferences for members of previously accurate speakers' groups on a common measure of epistemic trust. This result suggests that by at least age 4, children's trust in speaker testimony spreads to members of a previously accurate speaker's group.     

Cut-free common knowledge

Starting off from the infinitary system for common knowledge over multi-modal epistemic logic presented in [L. Alberucci, G. Jäger, About cut elimination for logics of common knowledge, Annals of Pure and Applied Logic 133 (2005) 73–99], we apply the finite model property to “finitize” this deductive system. The result is a cut-free, sound and complete sequent calculus for common knowledge.     

“Escape from Freedom”: Authoritarianism-related traits,political ideology,personality, and belief in free will/determinism

Philosophers have long speculated that authoritarianism and belief in determinism are functionally related. To evaluate this hypothesis, we assessed whether authoritarianism and allied personality and political variables predict varieties of belief in determinism in three community samples (N₁ = 566 to 20,010; N₂ = 500; N₃ = 419). Authoritarianism and allied variables manifested moderate to large positive correlations with both fatalistic and genetic determinism beliefs. Controlling for political conservatism did not meaningfully attenuate these relations. Further, openness was negatively related to fatalistic determinism beliefs and agreeableness was negatively related to genetic determinism beliefs. Taken together, our findings clarify the nature of relations between authoritarianism and general personality, on the one hand, and free will/determinism beliefs, on the other, and suggest intriguing intersections between worldviews and personality traits.     

The philosophical novelty of computer simulation methods

Reasons are given to justify the claim that computer simulations and computational science constitute a distinctively new set of scientific methods and that these methods introduce new issues in the philosophy of science. These issues are both epistemological and methodological in kind.     

Williamson on inexact knowledge

Timothy Williamson claims that margin for error principles govern all cases of inexact knowledge. I show that this claim is unfounded: there are cases of inexact knowledge where Williamson’s argument for margin for error principles does not go through. The problematic cases are those where the value of the relevant parameter is fixed across close cases. I explore and reject two responses to my objection, before concluding that Williamson’s account of inexact knowledge is not compelling.

Believing one’s reasons are good

Is it coherent to suppose that in order to hold a belief responsibly, one must recognize something else as a reason for it? This paper addresses this question by focusing on so-called “Inferential Internalist” principles, that is principles of the following form: in order for one to have positive epistemic status Ø in virtue of believing P on the basis of R, one must believe that R evidentially supports P, and one must have positive epistemic status Ø in relation to that latter belief as well. While such principles and their close relatives figure centrally in a wide variety of recent epistemological discussions, there is confusion in the literature about what, precisely, Inferential Internalism commits one to and whether it is so much as coherent. This paper (1) articulates a broader framework for understanding the notion of epistemic responsibility, (2) motivates Inferential Internalism on the basis of considerations about the basing relation, epistemic responsibility, and parallels with practical deliberation, (3) defends Inferential Internalism against charges of incoherence leveled by James Van Cleve and Paul Boghossian, and (4) shows that contrary to a currently widespread view, Inferential Internalism is coherent even if foundationalism and the a priori are rejected. The paper closes with a preliminary argument for an affirmative answer to the initiating question about the requirements of epistemic responsibility.
