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.

This paper aims to uncover where the disagreement between illusionism and anti-illusionism about phenomenal consciousness lies fundamentally. While illusionists claim that phenomenal consciousness does not exist, many philosophers of mind regard illusionism as ridiculous, stating that the existence of phenomenal consciousness cannot be reasonably doubted. The question is, why does such a radical disagreement occur? To address this question, I list various characterisations of the term “phenomenal consciousness”: (1) the what-it-is-like locution, (2) inner ostension, (3) thought experiments such as philosophical (...) zombies, inverted qualia and Mary’s room, (4) scientific knowledge about secondary properties, (5) theoretical properties such as being ineffable and being intrinsic, and (6) appearance/reality collapse. Then I examine whether each characterization provides (i) a dubitable sense of phenomenal consciousness in which the existence of phenomenal consciousness can be reasonably doubted, (ii) an indubitable sense in which its existence cannot be reasonably doubted, or (iii) a gray sense in which it is controversial whether its existence can be reasonably doubted. By doing so, I show that there is no single sense of phenomenal consciousness in which illusionists and anti-illusionists disagree whether the existence of phenomenal consciousness can be reasonably doubted. I conclude that the disagreement between illusionists and anti-illusionists is fundamentally terminological: while illusionists adopt a dubitable sense of phenomenal consciousness, anti-illusionists adopt an indubitable sense of phenomenal consciousness. Because of the extreme vagueness and ambiguity of the term “phenomenal consciousness”, illusionists and anti-illusionists fail to see that they talk about different senses of phenomenal consciousness.

Despite the prominence of doubt in philosophy since Descartes, the published philosophical literature includes no extended treatment of the nature of doubt. In this paper, I summarize the main contributions that have been made to the subject and then develop a commonsense functionalist account of doubt by specifying the functional role of doubt that something is the case. After adding two further wrinkles, I show how the resulting account can be used to address the questions of how doubt is related (...) to belief and whether suspension of judgment can be identified with doubt. Although the account is partisan, it should hold interest for those who favor other positions in the philosophy of mind, since much of the account can be taken on board by those in other camps, and the paper demonstrates how a sufficiently detailed account of doubt can be put to work addressing longstanding questions of interest across philosophical sub-disciplines.

Reasoning by jurors concerning whether an accused person should be convicted of committing a crime is a kind of casual inference. Jurors need to decide whether the evidence in the case was caused by the accused’s criminal action or by some other cause. This paper compares two computational models of casual inference: explanatory coherence and Bayesian networks. Both models can be applied to legal episodes such as the von Bu¨low trials. There are psychological and computational reasons for preferring the explanatory (...) coherence account of legal inference. (shrink)

The aim of the paper is to discuss and evaluate the role of positive emotions for cooperation in dialogical inquiry. I analyse dialogical interactions as vehicles for inquiry, and the role of positive emotions in knowledge gain is illustrated in terms of a case study taken from Socratic Dialogue, a contemporary method used in education for fostering group knowledge. I proceed as follows. After having illustrated the case study, I analyse it through the conceptual tools of distributed cognition and character-based (...) virtue epistemology, focusing on the two functions that emotions seem to play in the process of knowledge-building. These functions are motives for joint inquiry, and building blocks of the affective environment where the inquiry takes place. Positive emotions such as love and gratitude foster knowledge generation by providing an environment for posing questions and exploring aspects of a specific topic that a subject would not investigate outside of a group. This analysis helps me defend the thesis for which positive emotions are beneficial for cooperation. Because cooperation is the process that leads a group to cognitive transformation, emotions that support cooperation are beneficial for group knowledge creation as well. I assume that the beneficial function that positive emotions play within dialogical inquiry is the one of enhancement of cooperation. A beneficial factor not only comprises positive emotions that facilitate and strengthen cooperation among the agents in their epistemic practices, but also consists of such emotions that nurture the epistemic agents, enhancing their responsibility to generate epistemic goods, as propositional knowledge or explanatory understanding, for example. Thus, the responsibility toward the epistemic practice disclose the ethical dimension of group inquiry. (shrink)
