According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This article aims to fill this gap. It offers a precise characterisation of assertoric commitment, and applies it to define assertion. On the proposed view, acquiring commitment is not sufficient for asserting: (...) To assert, commitment must be acquired by explicitly presenting a proposition as true. (shrink)

In this paper, I spell out a new challenge for epistemic internalism that emerges out of the current debate on testimonial justification. Based on recent developments within this debate, one might argue as follows: Epistemic internalism can’t account for the justification of our testimony-based beliefs, because (1) we should conceive of testimonial justification along anti-reductionist lines and (2) anti-reductionism is incompatible with epistemic internalism. In response to this challenge, I show that, despite initial appearances, epistemic internalism and anti-reductionism are compatible (...) after all. Therefore, being an anti-reductionist with regard to testimonial justification doesn’t force one to reject epistemic internalism. In order to argue for this result, I will make use of resources provided by speech act theory. (shrink)

In this paper, I approach epistemic norms from an ontogenetic point of view. I argue and present evidence that to understand epistemic norms – e.g., scientific norms of methodology and the evaluation of evidence – children must first develop through their social interactions with others three key concepts. First is the concept of belief, which provides the most basic distinction on which scientific investigations rest: the distinction between individual subjective perspectives and an objective reality. Second is the concept of reason, (...) which in the context of science obligates practitioners to justify their claims to others with reasons by grounding them in beliefs that are universally shared within the community. Third is the concept of social norm, which is not primarily epistemic, but provides children with an understanding of norms as collective agreements. The theoretical argument is that all three of these concepts emerge not from just any kind of social interaction, but specifically from social interactions structured by the human species’ unique capacities for shared intentionality.

An impressive case has been built for the hypothesis that knowledge is the norm of assertion, otherwise known as the knowledge account of assertion. According to the knowledge account, you should assert something only if you know that it’s true. A wealth of observational data supports the knowledge account, and some recent empirical results lend further, indirect support. But the knowledge account has not yet been tested directly. This paper fills that gap by reporting the results of such a test. (...) The knowledge account passes with flying colors. (shrink)

Under which conditions are we epistemically justied to believe that what other people tell us is true? Traditionally, the answer has either been reductionist or anti-reductionist: Either our justication reduces to non-testimonial reasons, or we have a presumptive, though defeasible, right to believe what we are told. However, different cases pull in different directions. Intuitively, someone asking for the time is subject to different epistemic standards than a surgeon consulting a colleague before a dangerous operation. Following this line of thought, (...) this paper develops an account of testimonial justication that captures our reductionist as well as our anti-reductionist intuitions. It is argued that the speaker’s commitment to an epistemic norm, as well as the hearer’s understanding of that norm, gives the hearer a presumptive right to believe what she is told. However, this justication doesn’t apply to situations with high practical risks. Here, the hearer needs reductive reasons to believe that her interlocutor is especially qualied to give her the desired information. (shrink)

Research on children's developing moral cognition has mostly focused on their evaluation of, and reasoning about, others' intrinsically harmful (non-)verbal actions (e.g., hitting, lying). But assertions may have morally relevant (intended or unintended) consequences, too. For instance, if someone wrongly claims that “This water is clean!”, such an incorrect representation of reality may have harmful consequences to others. In two experiments, we investigated preschoolers' evaluation of others' morally relevant factual claims. In Experiment 1, children witnessed a puppet making incorrect assertions (...) that would lead to harm or to no harm. In Experiment 2, incorrect assertions would always lead to harm, but the puppet either intended the harm to occur or not. Children evaluated the puppet’s factual claim more negatively when they anticipated harmful versus harmless consequences (Experiment 1) and when the puppet’s intention was bad versus good over and above harmful consequences (Experiment 2). These findings suggest that preschoolers’ normative understanding is not limited to evaluating others’ intrinsically harmful transgressions, but also entails an appreciation of the morally relevant consequences of, and intentions underlying, others’ factual claims.

Assertion is fundamental to our lives as social and cognitive beings. Philosophers have recently built an impressive case that the norm of assertion is factive. That is, you should make an assertion only if it is true. Thus far the case for a factive norm of assertion been based on observational data. This paper adds experimental evidence in favor of a factive norm from six studies. In these studies, an assertion’s truth value dramatically affects whether people think it should be (...) made. Whereas nearly everyone agreed that a true assertion supported by good evidence should be made, most people judged that a false assertion supported by good evidence should not be made. The studies also suggest that people are consciously aware of criteria that guide their evaluation of assertions. Evidence is also presented that some intuitive support for a non-factive norm of assertion comes from a surprising tendency people have to misdescribe cases of blameless rule-breaking as cases where no rule is broken.

The age at which children acquire the concept of belief is a subject of debate. Many scholars claim that children master beliefs when they are able to pass the false belief test, around their fourth year of life. However, recent experiments show that children implicitly attribute beliefs even earlier. The dispute does not only concern the empirical issue of discovering children’s early cognitive abilities. It also depends on the kind of capacities that we associate to the very concept. I claim (...) that concept possession must be understood in terms of the gradual development of the abilities that underlie the concept in question. I also claim that the last step to possess the concept of belief requires children to understand how beliefs and desires are used in everyday explanations of people’s actions. Thus, I suggest that understanding folk psychology as an explanatory theory is what children lack when they fail the false belief test. (shrink)

Human social life is structured by social norms creating both obligations and entitlements. Recent research has found that young children enforce simple obligations against norm violators by protesting. It is not known, however, whether they understand entitlements in the sense that they will actively object to a second party attempting to interfere in something that a third party is entitled to do — what we call counter-protest. In two studies, we found that 3-year-old children understand when a person is entitled (...) to do something, and so they actively defend this person’s entitlement against unjustified interference from second parties. In some cases, they even enforce second-order entitlements, for example, in the case of ownership where an owner is entitled to entitle others to use the owner’s property. (shrink)

According to many scholars, prosociality, in particular altruism and empathic concern, is considered an important motivational factor both in adulthood and in the development of morality. So far, a large number of studies have addressed the development of children’s first-party prosociality and their third-party understanding of moral norms separately. In particular, there is much evidence that during the second year of life, young children develop empathic concern and sympathy for others in need in prosocial situations. Moreover, recent findings suggest that (...) 18-month-old infants already show some rudimentary forms of norm understanding in at least dyadic conventional situations. This rudimentary norm understanding is interpreted as second-personal normative expectations. Finally, 3-year-old children not only have descriptive expectations about morality, but also normative ones as suggested by their enforcement of moral norms as unaffected bystanders. However, the interrelation between prosociality and morality, in particular the prosocial motivational source of the early sense of morality remains unclear. This thesis aimed to investigate the developmental origins of morality in young children. In particular, it examines the relation between the two main aspects of uniquely human cooperation – prosociality and morality – from a developmental perspective. These two aspects are of particular importance, not only because they each play a key role in maintaining the unique human capacity for large-scale cooperation but also because of their close relation to each other. The present thesis therefore focused on three guiding questions that are essential for the ontogeny of morality and its relation to young children’s prosocial motivation to understand, adhere to, and enforce moral norms: What are the developmental origins of morality? What is the underlying prosocial motivation for children's normative appreciation of morality? What is the scope of morality? Study 1 investigated the developmental origins of morality in 18-month-old infants. A novel eye-tracking paradigm was used to examine whether infants differentiate between prototypical moral and conventional violations. In a between-subjects-design, children watched the same video clip whose audio stream differed according to condition. In the first two conditions, an instructor told an observer to destroy a picture with a particular tool chosen from two available tools. In the moral violation condition, the instructor forbade the observer to destroy the picture at all. In all three conditions, the observer then grasped tool B and destroyed the picture, which led to three different situations. Infants differentiated between two types of conventional norm situations in their anticipatory looking. Moreover, they showed a larger relative increase in pupil dilation in response to a moral violation than to a conventional violation. These findings suggest that 18-month-old infants have third-party descriptive expectations about the distinction between conventional and moral violation situations. Moreover, they provide the first evidence that empathic concern may be a decisive capacity for the distinction between these two violation situations. Study set 2 looked at the underlying prosocial motivation for the appreciation of morality as a normative notion in 3-year-old children. In three experiments, children were given a third-party fairness task and two different prosocial tasks. To investigate whether the children have a proper norm understanding of fairness by looking not only at norm adherence, but also at norm enforcement, a spontaneous protest paradigm was used. In Experiment 1, children protested and corrected unequal allocations, suggesting a normative understanding of third-party fairness. Experiment 2 assessed whether children’s normative expectations about fairness have a moral dimension. To do so, children observed a distributor who followed or violated an authority’s command to allocate resources unequally. Again, despite the authority’s dictate to act unequally, children protested more against unequal versus equal allocations. In Experiment 3, results show that children enforced fairness norms by altruistic punishment in the sense of restorative justice. While in Experiment 1 and 2 I found a positive relation of protest behavior and emotional sharing, in Experiment 3 children’s altruistic punishment was associated with their own costly sharing behavior. Finally, in Study 3, I explored the scope of morality in 5-to 6-year-old children in a typical intergroup context. Here, I investigated whether decategorization – a candidate mechanism to overcome in-group bias by emphasizing the individual person – would lead preschoolers to treat in-group and out-group members equally when sharing resources in a dictator game. I found that preschoolers shared more resources with an in-group than with an out-group recipient when social category membership was emphasized. When individuating information was emphasized, however, children shared the same with in-group and out-group individuals. Taken together, the empirical studies of this dissertation provide a novel overview of the prosocial roots of children's developing morality. In particular, the present findings suggest that the ability to feel sympathy may be critical for the development of the moral-conventional distinction and that 18-month-old infants, at minimum, have third-party descriptive expectations about that distinction. The ontogeny of fairness norms can be characterized as moral in that it is associated with 3-year-old children’s developing concern for the welfare of others in different contexts. The presentation of out-group members as individuals may be a powerful tool to reduce in-group bias and to foster equal treatment of in-group and out-group members in 5- to 6-year-old preschool children.

Within the growing developmental literature on children's testimonial learning, the emphasis placed on children's evaluations of testimonial evidence has shielded from view some of the more collaborative dimensions of testimonial learning. Drawing on recent philosophical work on testimony and interpersonal trust, we argue for an alternative way of conceptualizing the social nature of testimonial learning. On this alternative, some testimonial learning is the result of a jointly collaborative epistemic activity, an activity that aims at the epistemic goal of true belief, (...) but that does so by means of an irreducibly social process.

How do human children come up to carve up and think of the world around them in its most general and abstract structure? And to which degree are these general forms of viewing the world shared by other animals, notably by non-human primates? In response to these questions of what could be called comparative metaphysics, this paper discusses new evidence from developmental and comparative research to argue for the following picture: human children and non-human primates share a basic framework of (...) natural ontology: they think about their natural surroundings in essentialist ways in terms of natural kind objects constituted by their essential properties, and in generic terms as governed by general descriptive regularities. In contrast, there is a great divide when it comes to how human children and non-human primates carve up their social environment: only human children then go on to use their essentialist and generic thinking for developing a distinctively social ontology, to conceive of their surrounding in terms of socially constituted objects governed by general prescriptive norms.

In this paper we address the question how children come to understand normativity through simple forms of social interaction. A recent line of research suggests that even very young children can understand social norms quite independently of any moral context. We focus on a methodological procedure developed by Rakoczy et al., Developmental Psychology, 44, 875–881, that measures children’s protest behaviour when a pre-established constitutive rule has been violated. Children seem to protest when they realize that rule violations are not allowed (...) or should not have happened. We point out that there is more than one possible explanation for children’s reactions in these studies. They could be due to disobeying an authority, an inability to follow a rule, or the violation of an empirical expectation due to the mismatch between statement and action. We thus question whether it would still count as an indicator for normative understanding if children responded to aspects of the game other than the violation of a constitutive rule and conclude that the protesting behavior, when taken in isolation, does not suffice as evidence for normative understanding.

We extend Tomasello's discussion of children's developing sense of obligation to testimonial learning. First, we review a battery of behaviors in testimonial exchanges that parallel those described by Tomasello. Second, we explore the variable ways in which children hold others accountable, suggestive that children's evaluations of moral and epistemic responsibilities in joint collaborative activities are distinct.
