This paper explores ‘reasonable doubt’ as an enlightening notion to think of reasoning and decision-making generally, beyond the judicial domain. The paper starts from a decision-theoretic understanding of the notion, whereby it can be defined in terms of degrees of belief and a probabilistic confirmation threshold for action. It then highlights some of the limits of this notion, and proposes a richer analysis of epistemic states and reasoning through the lens of ‘reasonable doubt’, which in turn is likely to supplement (...) the DT framework. The strategy consists in fighting on two fronts: with DT, the paper claims that there is no absolute notion of ‘reasonable doubt’ but, pace DT, it shows that reasonable doubt cannot be accounted for only in terms of degrees of belief and probabilistic threshold. We argue that the lens of reasonable doubt sheds light on aspects of belief dynamics, as well as of the nature of epistemic attitudes, which are often obscured by belief-centred approaches. In particular, when it comes to acknowledging the necessary ignorance and irreducible uncertainty that we face in our everyday-life decisions, studying the various facets of doubt rather than focusing on what can be believed, enables one to do justice to the richness and diversity of the mental states in play.

Checking is one of the most common compulsive actions performed by patients with Obsessive- compulsive disorder (OCD) (APA, 2013; Abramowitz, McKay, Taylor, 2008). Incessant checking is undeniably problematic from a practical point of view. But what is epistemically wrong with checking again (and again)? The starting assumption for this paper is that establishing what goes wrong when individuals check their stove ten times in a row requires understanding the nature of the doxastic attitude that compulsive re-checkers are in, as they (...) go back to perform another check. Does the re-checker know that the stove is off, and is thus looking for more of what she already has? Or is she an inquirer who repeatedly loses her knowledge and finds herself inquiring again and again into the same question? In this paper I present and discuss what I see as the three main hypotheses currently available on the market, and I suggest a refinement. (shrink)

A Lockean metaphysics of belief that understands outright belief as a determinable with degrees of confidence as determinates is supposed to effect a unification of traditional coarse-grained epistemology of belief with fine-grained epistemology of confidence. But determination of belief by confidence would not by itself yield the result that norms for confidence carry over to norms for outright belief unless belief and high confidence are token identical. We argue that this token-identity thesis is incompatible with the neglected phenomenon of “mistuned (...) knowledge” – knowledge in the absence of rational confidence. We show how partial epistemological unification can be secured, even without token identity, given determination of outright belief by degrees of confidence. Finally, we suggest a direction for the pursuit of thoroughgoing epistemological unification. (shrink)
