A review with commentary on the book, Understanding Beliefs, Nils J. Nilsson, MIT Press, 2014.

What beliefs are, what they do for us, how we come to hold them, and how to evaluate them. Our beliefs constitute a large part of our knowledge of the world. We have beliefs about objects, about culture, about the past, and about the future. We have beliefs about other people, and we believe that they have beliefs as well. We use beliefs to predict, to explain, to create, to console, to entertain. Some of our beliefs we call theories, and (...) we are extraordinarily creative at constructing them. Theories of quantum mechanics, evolution, and relativity are examples. But so are theories about astrology, alien abduction, guardian angels, and reincarnation. All are products (with varying degrees of credibility) of fertile minds trying to find explanations for observed phenomena. In this book, Nils Nilsson examines beliefs: what they do for us, how we come to hold them, and how to evaluate them. We should evaluate our beliefs carefully, Nilsson points out, because they influence so many of our actions and decisions. Some of our beliefs are more strongly held than others, but all should be considered tentative and changeable. Nilsson shows that beliefs can be quantified by probability, and he describes networks of beliefs in which the probabilities of some beliefs affect the probabilities of others. He argues that we can evaluate our beliefs by adapting some of the practices of the scientific method and by consulting expert opinion. And he warns us about “belief traps”—holding onto beliefs that wouldn't survive critical evaluation. The best way to escape belief traps, he writes, is to expose our beliefs to the reasoned criticism of others. (shrink)

In this paper, I defend a well-known theory of belief reports from an important objection. The theory is Russellianism, sometimes also called `neo-Russellianism', `Millianism', `the direct reference theory', `the "Fido"-Fido theory', or `the naive theory'. The objection concernssubstitution of co-referring names in belief sentences. Russellianism implies that any two belief sentences, that differ only in containing distinct co-referring names, express the same proposition (in any given context). Since `Hesperus' and `Phosphorus' both refer to the planet Venus, this (...) view implies that all utterances of (1) and.. (shrink)

In this article, we postulate that belief understanding unfolds in two steps over ontogenetic time. We propose that belief understanding begins in interactive scenarios in which infants and toddlers respond directly and second-personally to the actions of a misinformed agent. This early understanding of beliefs is practical and grounded in the capacity for perspective-taking. Practical belief understanding guarantees effective interaction and communication with others who are acting on false assumptions. In a second step, (...) children, at preschool age, acquire the capacity to reflect on and arrive at third-personal judgments about a misinformed agent’s perspective. This capacity is theoretical and grounded in the ability to “confront” perspectives. It allows children to understand that beliefs can misrepresent the state of the world and to predict what (past, future, or hypothetical) actions follow from these beliefs. We conclude with ideas on how practical perspective-taking develops into theoretical perspective-confronting in early ontogeny. (shrink)

Understanding artificial intelligence and belief formation have interesting bidirectional synergies. From explaining the logical derivation of beliefs and their internal consistency, to giving a quantitative account of mightiness, AI still has plenty of unexploited metaphors that can illuminate belief formation. In addition, acknowledging that AI should integrate itself with our belief processes makes it possible to focus on more promising lines such as Interpretable Machine Learning.

The study of belief is expanding and involves a growing set of disciplines and research areas. These research programs attempt to shed light on the process of believing, understood as a central human cognitive function. Computational systems and, in particular, what we commonly understand as Artificial Intelligence (AI), can provide some insights on how beliefs work as either a linear process or as a complex system. However, the computational approach has undergone some scrutiny, in particular about the differences between (...) what is distinctively human and what can be inferred from AI systems. The present article investigates to what extent recent developments in AI provide new elements to the debate and clarify the process of belief acquisition, consolidation, and recalibration. The article analyses and debates current issues and topics of investigation such as: different models to understand belief, the exploration of belief in an automated reasoning environment, the case of religious beliefs, and future directions of research.

In recent years there has been a resurgence of interest among epistemologists in the nature of understanding, with some authors arguing that understanding should replace knowledge as the primary focus of epistemology. But what is understanding? According to what is often called the standard view, understanding is a species of knowledge. Although this view has recently been challenged in various ways, even the critics of the standard view have assumed that understanding requires justification and (...) class='Hi'>belief. I argue that it requires neither. If sound, these arguments have important upshots not only for the nature of understanding, but also for its distinctive epistemic value and its role in contemporary epistemology. (shrink)

Dellsén (2016a) argues that understanding requires neither justification nor belief. I object that ridding understanding of justification and belief comes with the following costs. (i) No claim about the world can be inferred from what we understand. (ii) We run into either Moore’s paradox or certain disconcerting questions. (iii) Understanding does not represent the world. (iv) Understanding cannot take the central place in epistemology. (v) Understanding cannot be invoked to give an account of (...) scientific progress. (vi) It is not clear how misunderstanding arises. (shrink)

The etiology of a perceptual belief can seemingly affect its epistemic status. There are cases in which perceptual beliefs seem to be unjustified because the perceptual experiences on which they are based are caused, in part, by wishful thinking, or irrational prior beliefs. It has been argued that this is problematic for many internalist views in the epistemology of perception, especially those which postulate immediate perceptual justification. Such views are unable to account for the impact of an experience’s etiology (...) on its justificational status, McGrath, Siegel, and Vahid ). Our understanding of what we have been told can also be affected by, for example, wishful thinking or irrational background beliefs. I argue that testimonial beliefs based on such states of understanding can thus be rendered unjustified. This is problematic not only for internalist immediate justification views of testimony, but also for some externalist views, such as the form of proper functionalism endorsed by Burge, and Graham. The testimonial version of the argument from etiology, unlike the perceptual variant, does not rest on the controversial hypothesis that perception is cognitively penetrable. Furthermore, there is a stronger case for the claim that testimonial justification can be undermined by etiological effects since, I argue, testimonial beliefs can be based on the background mental states which affect our understanding of what is said, and our states of understanding are rationally assessable.

Should we regard Jennifer Lackey’s ‘Creationist Teacher’ as understanding evolution, even though she does not, given her religious convictions, believe its central claims? We think this question raises a range of important and unexplored questions about the relationship between understanding, factivity and belief. Our aim will be to diagnose this case in a principled way, and in doing so, to make some progress toward appreciating what objectual understanding—i.e., understanding a subject matter or body of information—demands (...) of us. Here is the plan. After some ground clearing in §1, §2 outlines and motivates a plausible working model—moderate factivity—for characterising the sense in which objectual understanding should be regarded as factive. §3 shows how the datum that we can understand false theories can, despite initial suggestions to the contrary, be assimilated straightforwardly within the moderate factivity model. §4 highlights how the inverse kind of case to that explored in §3—viz., a variant of Lackey’s creationist teacher case—poses special problems for moderate factivity. With reference to recent work on moral understanding by Hills, §5 proposes a solution to the problem, and §6 attempts to diagnose why it is that we might originally have been led to draw the wrong conclusion.

Comment on Dean Pettit, who replies in same issue.

A natural view is that linguistic understanding is a source of justification or evidence: that beliefs about the meaning of a text or speech act are prima facie justified when based on states of understanding. Neglect of this view is largely due to the widely held assumption that understanding a text or speech act consists in knowledge or belief. It is argued that this assumption rests, in part, on confusing occurrent states of understanding and dispositions (...) to understand. It is then argued that occurrent states of understanding are not states of belief of knowledge since a subject may fail to believe that a text or speech act means what she understands it to mean if she doubts the reliability or truth- fulness of that understanding. States of understanding, it is maintained, belong in the same epistemic category as states of perception and memory. (shrink)

The dominant account of human social understanding is that we possess a 'folk psychology', that we understand and can interact with other people because we appreciate their mental states. Recently, however, philosophers from the phenomenological tradition have called into question the scope of the folk psychological account and argued for the importance of 'online', non-mentalistic forms of social understanding. In this paper I critically evaluate the arguments of these phenomenological critics, arguing that folk psychology plays a larger role (...) in human social understanding than the critics suggest. First, I use standard false-belief tasks to spell out the commitments of the folk psychological picture. Next, I explicate the critics' account in terms of Michael Wheeler's distinction between online and offline intelligence. I then demonstrate the challenge that false-belief understanding -- a paradigm case of mental state understanding -- poses to the critics' online, non- mentalistic account. Recent research on false-belief understanding illustrates that mental state understanding comes in both online and offline forms. This challenges the critics' claim that our online social understanding does not require folk psychology. (shrink)

It seems uncontroversial that Dalton wrongly believed that atoms are indivisible. However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases (...) such as the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought.

This article discusses how to deal with the relations between different cultural perspectives in classrooms, based on a proposal for considering understanding and knowledge as goals of science education, inspired by Dewey’s naturalistic humanism. It thus combines educational and philosophical interests. In educational terms, our concerns relate to how science teachers position themselves in multicultural classrooms. In philosophical terms, we are interested in discussing the relations between belief, understanding, and knowledge under the light of Dewey’s philosophy. We (...) present a synthesis of Dewey’s theory of inquiry through his naturalistic humanism and discuss its implications for the concepts of belief, understanding, and knowledge, as well as for the goals of science teaching. In particular, we highlight problems arising in the context of possible conflicts between scientific and religious claims in the school environment that result from totalitarian positions. We characterize an individual’s position as totalitarian if he or she takes some way of thinking as the only one capable of expressing the truth about all that exists in the world, lacks open-mindedness to understand different interpretative perspectives, and attempts to impose her or his interpretation about the facts to others by violent means or not. From this stance, any other perspective is taken to be false a priori and, accordingly, as a putative target to be suppressed or adapted to the privileged way of thinking. We argue, instead, for a more fallibilist evaluation of our own beliefs and a more respectful appraisal of the diversity of students’ beliefs by both students and teachers. (shrink)

In his famous 1979 article 'A Puzzle About Belief' Saul Kripke presents two puzzles regarding belief attribution, and he uses them to cast doubt on classical substitution arguments against the Millian view that a proper name has a 'denotation' (or reference) but no 'connotation' (or sense). In this article, I present Kripke's puzzles in what I take to be their most revealing form, discuss their relevance to the abovementioned arguments, briefly survey the ways in which philosophers have responded (...) to these puzzles, and call attention to some issues related to the puzzles that have yet to receive the consideration they deserve.

Allan Hazlett challenges the philosophical assumption of the value of true belief. He critiques the view that true belief is better for us than false belief, and the view that truth is "the aim of belief". An alternative picture is provided, on which the fact that some people love truth is all there is to "the value of true belief".

What is it to understand another speaker’s utterance? A natural view is that such understanding requires at least the acquisition of propositional knowledge of the utterance’s meaning. This view is challenged by cases in which it correctly seems to a hearer H as though an utterance means such-and-such, but where H doesn’t form the belief that it means such-and-such due to a misleading defeater. Such cases have been claimed to be examples of understanding without belief, and (...) a fortiori of understanding without knowledge. The paper examines this argument in detail and defends a mixed verdict: While the argument succeeds in showing that there is a reading of attributions of utterance understanding on which the natural view is false, such attributions also have a different reading on which the natural view may well be true for all the argument shows. In making the case for the second half of this claim, the paper gives center stage to the close intuitive connection between utterance understanding and communicative success. (shrink)

This paper uses recent research in developmental psychology regarding the acquisition of the concept of belief in young children to explore the contrast between a disposition-based account of the principles underlying linguistic communication and the representative and highly influential intention-based accounts of assertional practice advanced by David Lewis and Donald Davidson. Indeed, evidence from recent work in developmental psychology would seem to suggest that disposition-based accounts are not only possible accounts of the acquisition of competence in assertional practice, but (...) are in fact better than their rivals in explaining the way such competence is actually acquired.

My purpose in this paper is to defend the legitimacy of different religious systems by showing that they arise naturally as a consequence of the fact that we are linguistic beings. I will show that we do not need to presume that such belief systems all have something in common, and that even if they did we would most probably be unaware of it. I shall argue, however, that this lack of a common core does not mean that (...) class='Hi'>understanding between different belief systems is impossible, and that, in fact, a dialogue between them is possible without one system being reduced to another. I will defend these ideas through the use of some principles expounded in Wittgenstein’s On Certainty, especially the world-picture concept. (shrink)

Gene‐editing research is a complex science and foreign in most communities including Botswana. Adopting a qualitative deliberative framework with 109 participants from 7 selected ethnic communities in Botswana, we explored the perceptions of local communities on cultural values, norms, and beliefs that may motivate or deter likely participation in the use of gene‐editing related research. What emerged as the ethnic community's motivators for research participation include the potential for gene‐editing technologies to promote access to individualized medications, and the possibility of (...) protecting family members from genetic related diseases. Deterrents for research participation include cultural values such as implications of lineage for chieftainship, trust, fear or anxiety, uncertainty, and sensitivity on the use of gene‐editing. Findings of our study have implications for continuous engagement with local communities to explore potential ways of addressing cultural sensitivities that can further deter their participation in future gene‐editing related research.

This volume provides a framework for approaching and understanding mental normativity. It presents cutting-edge research on the ethics of belief as well as innovative research beyond the normativity of belief—and towards an ethics of mind. By moving beyond traditional issues of epistemology the contributors discuss the most current ideas revolving around rationality, responsibility, and normativity. -/- The book’s chapters are divided into two main parts. Part I discusses contemporary issues surrounding the normativity of belief. The essays (...) here cover topics such as control over belief and its implication for the ethics of belief, the role of the epistemic community for the possibility of epistemic normativity, responsibility for believing, doxastic partiality in friendship, the structure and content of epistemic norms, and the norms for suspension of judgment. In Part II the focus shifts from the practical dimensions of belief to the normativity and rationality of other mental states—especially blame, passing thoughts, fantasies, decisions, and emotions. These essays illustrate how we might approach an ethics of mind by focusing not only on belief, but also on debates about responsibility, rationality, These essays illustrate how we might approach an ethics of mind by focusing not only on belief, but also more generally on debates about responsibility and rationality, as well as on normative questions concerning other mental states or attitudes. -/- The Ethics of Belief and Beyond paves the way towards an ethics of mind by building on and contributing to recent philosophical discussions in the ethics of belief and the normativity of other mental phenomena. It will be of interest to upper-level students and researchers working in epistemology, ethics, philosophy of action, philosophy of mind, and moral psychology. (shrink)

I try in this article to shed some light on what it is and what it is not to understand certain kinds of beliefs, of which religious belief is the most prominent instance. Much has been written on the subject, and I make no apologies either for taking for granted a context for discussion, or for disregarding a number of familiar issues. I try, in particular, to explain why a rather curious thesis about understanding religious belief has (...) found wide acceptance when, on the face of it, it cannot possibly be correct. I begin with one or two points about belief; I then take what I hope is a fresh look at two theses about understanding religious belief; and finally I draw some tentative conclusions about puzzlement, understanding and understandability.

This study examines the spontaneous use of embodied egocentric transformation in understanding false beliefs in the minds of others. EET involves the participants mentally transforming or rotating themselves into the orientation of an agent when trying to adopt his or her visuospatial perspective. We argue that psychological perspective taking such as false belief reasoning may also involve EET because of what has been widely reported in the embodied cognition literature, showing that our processing of abstract, propositional information is (...) often grounded in concrete bodily sensations which are not apparently linked to higher cognition. In Experiment 1, an agent placed a ball into one of two boxes and left. The ball then rolled out and moved either into the other box or back into the original one. The participants were to decide from which box they themselves or the agent would try to recover the ball. Results showed that false belief performance was affected by increased orientation disparity between the participants and the agent, suggesting involvement of embodied transformation. In Experiment 2, false belief was similarly induced and the participants were to decide if the agent would try to recover the ball in one specific box. Orientation disparity was again found to affect false belief performance. The present results extend previous findings on EET in visuospatial perspective taking and suggest that false belief reasoning, which is a kind of psychological perspective taking, can also involve embodied rotation, consistent with the embodied cognition view.

Traditional theories of mindreading tend to focus exclusively on attributing beliefs and desires to other agents. The literature emphasizes belief attribution in particular, with numerous debates over when children develop the concept of belief, how neurotypical adult humans attribute beliefs to others, whether non-human animals have the concept of belief, etc. I describe a growing school of thought that the heavy focus on belief leaves traditional theories of mindreading unable to account for the complexity, diversity, and (...) messiness of ordinary social interactions. I present a few broader, more comprehensive conceptions of mindreading that take into account how stereotypes, character trait inferences, social biases, and more influence how we understand and interact with others. These broader conceptions of mindreading promise to be more empirically adequate and have fruitful application to various debates in philosophy and cognitive science. (shrink)
