Mercier & Sperber (M&S) argue for their argumentative theory in terms of communicative abilities. Insights can be gained by extending the discussion beyond human reasoning to rodent and robot navigation. The selection of arguments and conclusions that are mutually reinforcing can be cast as a form of abductive reasoning that I argue underlies the construction of cognitive maps in navigation tasks.

Short abstract (98 words). Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given humans’ exceptional dependence on communication and vulnerability to misinformation. A wide range of (...) evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. (shrink)

Since political polarization significantly impacts contemporary politics and democracy, much of the research in the social sciences is dedicated to this topic. In recent times, philosophers joined the discussion related to the research on political polarization, primarily in the fields of political philosophy and political epistemology. The main aim of this paper is philosophical analysis of some dominant explanations of political polarization, but also to propose solutions for a way out of political polarization from the perspective of political philosophy. In (...) a nutshell, to find solutions for a way out of political polarization, I will be looking in the direction of boosting epistemic rationality and fostering communication in conditions of tolerance and equality.

The "myside bias'' in evaluating arguments is an empirically well-confirmed phenomenon that consists of overweighting arguments that endorse one's beliefs or attack alternative beliefs while underweighting arguments that attack one's beliefs or defend alternative beliefs. This paper makes two contributions: First, it proposes a probabilistic model that adequately captures three salient features of myside bias in argument evaluation. Second, it provides a Bayesian justification of this model, thus showing that myside bias has a rational Bayesian explanation under certain conditions.

The my-side bias is a well-documented cognitive bias in the evaluation of arguments, in which reasoners in a discussion tend to overvalue arguments that confirm their prior beliefs, while undervaluing arguments that attack their prior beliefs. The first part of this paper develops and justifies a Bayesian model of myside bias at the level of individual reasoning. In the second part, this Bayesian model is implemented in an agent-based model of group discussion among myside-biased agents. The agent-based model is then (...) used to perform a number of experiments with the objective to study whether the myside bias hinders or enhances the ability of groups to collectively track the truth, that is, to reach the correct answer to a given binary issue. An analysis of the results suggests the following: First, whether the truth-tracking ability of groups is helped or hindered by myside bias crucially depends on how the strength of myside bias is differentially distributed across subgroups of discussants holding different beliefs. Second, small groups are more likely to track the truth than larger groups, suggesting that increasing group size has a detrimental effect on collective truth-tracking through discussion. (shrink)

The statement everyone wants to live a fulfilled and happy life may seem simple, self-evident, and even trivial at first glance. However, upon closer philosophical analysis, can we unequivocally assert that people are truly focused on well-being? Assuming they are, the question becomes: what guidelines should be followed and how should one behave in order to achieve true well-being and attain their goals? One popular viewpoint is that cultivating moral virtues and personal qualities is essential for a life of "true" (...) well-being, rather than mere pleasure. This perspective is not particularly original, as it was advocated quite clearly by Aristotle. However, we must ask: what guarantees that virtue will lead to well-being? Can we really ignore the common-sense doubt that virtue (and moral life), as Kant points out, may not be rewarded with any form of well-being or "happiness" in the broadest sense during our earthly existence? How might we address this doubt? If questions about the relationship between happiness and virtue have been asked since ancient times, why don't we have definitive answers yet? Perhaps there is something wrong with the questions themselves, as is often the case in philosophy. Views on this relationship have influenced the modification of theories that philosophers have put forth in order to provide satisfactory answers. One such theory is the renewed and modernized ethics of virtue, which places the greatest emphasis on building an individual's moral character, assuming that Aristotelian character virtues such as courage, honesty, generosity, prudence, self-control, and compassion will enable us to lead a happy and fulfilling life. "Virtues" refer to a wide range of "excellences" or activities that individuals can use to perfect themselves. For example, an ordinary person might accept that courage can make their life more fulfilling, but it's important to recognize that virtues cannot be acquired overnight. Furthermore, many people believe that virtues are innate qualities that one either possesses or lacks. In contrast, ethics of virtue provides guidance and instructions for developing virtues over extended periods of time, as well as for continuously "practicing" the development of moral characteristics that will make us better individuals. The central and most significant concept in ethics of virtue is the golden mean, which can be interpreted in various ways. Essentially, ethics of virtue offers a path to a life filled with pleasure, harmony, and virtuous action. However, this collection of essays, Virtues and Vices: Between Ethics and Epistemology, is not exclusively concerned with virtues or ethics. Knowledge, as well as the processes of belief formation and justification of those beliefs, are also essential to ethics of virtue. Going back to the systematic Greek philosopher and his teacher, we can emphasize that virtues and knowledge are inseparable. Without the epistemology of virtues, even a thematic collection like this one would be incomplete. The Epistemology of Virtue is a relatively new branch of philosophy that has emerged as a response to questions about the value-neutrality of science. For a long time, the separation of values and scientific inquiry has been viewed as the correct methodological approach. However, it is clear that every scientist is also a human being with their own virtues and flaws. It is naive to assume that a scientist can leave their values and moral qualities outside the laboratory and treat their colleagues in the team differently than they would treat other people in their everyday life. Taking this into account, we can notice that Epistemology of Virtue is a theory that examines the influence of virtues on the processes of acquiring knowledge. Epistemic virtues refer to qualities that enable individuals to acquire knowledge and make reliable judgments. These virtues include traits such as openness to diverse testimonies and arguments, critical thinking, a tendency to question one's own assumptions, and the ability to identify errors in one's own thought processes. Just like in virtue ethics, the Epistemology of Virtue raises the question of how we can cultivate the necessary virtues and how these virtues can have a positive impact on both individuals and society. The field also explores how epistemic virtues can be put into practice, such as in educational settings, scientific research, and various social activities. Finally, we turn to a topic that is often overlooked in philosophy - human flaws. While ethics typically views flaws as the opposite of virtues, requiring correction both individually and socially, the Epistemology of Virtue questions what happens when flaws occur in knowledge-related qualities. Do these flaws also need to be eliminated, or are they an inherent part of the process of acquiring knowledge and making judgments? At first glance, prejudices, stereotypes, dogmatism, conformism, closed-mindedness towards arguments and evidence, as well as uncritical acceptance of authority, can all hinder our ability to acquire knowledge. Epistemologists view these qualities as vices, rather than flaws like ethicists do. The Epistemology of Vices is the newest of the three branches of philosophy covered in this thematic collection, and it examines the ways in which false and untrue beliefs develop and persist in society. This area of study seeks to answer questions about how people form delusions and whether it is possible to overcome them. On the other hand, the Epistemology of Virtue is like the "older brother" that supervises these vices. It contributes to the investigation and overcoming of vices by developing virtues that enable individuals to more accurately assess the truthfulness of their beliefs. However, even though vices can have a destructive impact on knowledge acquisition, the question remains: are vices always detrimental in every context? Conversely, can virtues be detrimental? For example, does a virtue like solidarity sometimes hinder the efficient formation of true beliefs in time-sensitive situations such as finding a vaccine to combat a virus pandemic? Can vices be useful? Can stubbornness and uncooperativeness sometimes help a research team by allowing two sides to reach the same goal through different paths? Within this collection, some of these questions will receive answers, some of which may confirm existing impressions, while others may surprise readers. The thematic collection, Virtues and Vices: Between Ethics and Epistemology, consists of four interesting chapters and 21 papers that cover the selected topic through the prism of philosophical disciplines such as ethics, epistemology, the history of philosophy, philosophy of mind, political philosophy, and philosophy of science. In this introduction, we will not discuss the contents of the articles so as not to disrupt the intended integral approach to reading the collection. A significant feature of this collection is the continuity that extends from one paper to another, from topic to topic, and from problem to problem. Lastly, we would like to express our gratitude to the Faculty of Philosophy at the University of Belgrade for their support in realizing this collection, as well as to our colleagues from the Department and Institute of Philosophy who have made this collection a relevant and significant achievement with their contributions. We are also thankful to the reviewers of the collection as a whole, as well as to the referees of individual articles, who have provided us with detailed comments and remarks that have made this collection clearer and more comprehensive. We owe a special thanks to our colleagues from Zagreb, Rijeka, and Maribor, whose exceptional papers have contributed to making this collection an unabashed international contribution to debates about the ethics and epistemology of virtues and vices.

Sometimes inquirers may rationally pursue a theory even when the available evidence does not favor that theory over others. Features of a theory that favor pursuing it are known as considerations of promise or pursuitworthiness. Examples of such reasons include that a theory is testable, that it has a useful associated analogy, and that it suggests new research and experiments. These reasons need not be evidence in favor of the theory. This raises the question: what kinds of reasons are provided (...) by pursuitworthiness considerations? Are they epistemic reasons or practical reasons? I argue that pursuitworthiness considerations are a kind of non-evidential epistemic reason, which I call an inquisitive reason. In support of this, I first point out two important similarities between the traditional pursuitworthiness considerations discussed in philosophy of science, which I call promise reasons, and certain social epistemic reasons that I call social inquisitive reasons. Specifically, both kinds of reason (1) favor pursuing a theory in a non-evidential way, and (2) concern promoting successful inquiry. I then propose recognition of a new category of normative reason: inquisitive reasons. This category contains both promise and social inquisitive reasons. Finally, I argue that inquisitive reasons share three essential features with previously recognized epistemic reasons: a connection to epistemic aims, explanatory independence, and the presence of a specific right-kind/wrong-kind reasons distinction. Each of these features have been used to argue that evidence should be treated as part of a distinct, independent domain of epistemic normativity. Since inquisitive reasons share these features, they too should be considered part of this independent epistemic domain. Thus, inquisitive reasons, including pursuitworthiness considerations, are epistemic reasons. (shrink)

In this paper, we examine whether it is possible to improve democracy by encouraging ordinary citizens to participate in political decision-making and if participation in deliberative institutions can make citizens more competent decision-makers. By using qualitative data, we analyze the discussion from the Belgrade citizens? assembly focused on the topic of expanding the pedestrian zone in the city center. The CA was organized in Serbia for the first time, as part of a research project aimed at promoting and advancing innovative (...) democratic practices in the Western Balkans. The goal was to encourage the involvement of citizens in discussions of public interest. Our hypothesis was that, through the process of participation and deliberation in CA, ordinary citizens can make reasonable and informed choices, increase their knowledge of the issue discussed, and become more motivated to participate in political decision-making on the local level. Our qualitative content analysis suggests that deliberation had a positive impact on participants? knowledge of the chosen topic of the assembly. It also shows that citizens used exhaustive explanations rather than brief statements, could differentiate the good arguments from the bad, and more often appealed to general rather than private interests. Participants in the assembly reported a significant increase in interest in political decision-making that affects their lives, as well as a sense of being informed about politics. Finally, we wanted to draw attention to the challenges and open questions that remain, namely those that concern the impact of a deliberative body on political decision-making in the real world.

This paper articulates a general distinction between two important communicative ideals—expressive sincerity and discursive integrity—and then uses it to analyze problems with political debate in contemporary democracies. In the context of philosophical discussions of different forms of trustworthiness and debates about deliberative democracy, self-knowledge, and moral testimony, the paper develops three arguments for the conclusion that, although expressive sincerity is valuable, we should not ignore discursive integrity in thinking about how to address problems with contemporary political debate. The paper concludes (...) with a brief discussion of a strategy for improving discursive integrity within public political debate by reflecting on which principles of responsible public debate would promote better democratic decision making.

Epistemic democracy is standardly characterized in terms of “aiming at truth”. This presupposes a veritistic conception of epistemic value, according to which truth is the fundamental epistemic goal. I will raise an objection to the standard (veritistic) account of epistemic democracy, focusing specifically on deliberative democracy. I then propose a version of deliberative democracy that is grounded in non-veritistic epistemic goals. In particular, I argue that deliberation is valuable because it facilitates empathetic understanding. I claim that empathetic understanding is an (...) epistemic good that doesn’t have truth as its primary goal. (shrink)

Sperber and Mercier maintain that argumentation is a meta-representational module. In their evolutionary view of argumentation, the function of this module would be to regulate the flow of information between interlocutors through persuasiveness on the side of the communicator and epistemic vigilance on the side of the audience. The aim of this paper is to discuss this definition of argumen-tation by analyzing what they mean by “communicator’s persuasiveness” and “audience epistemic vigilance”.

ABSTRACT Mutz argues that there is an inverse correlation between deliberation and participation. However, the validity of this conclusion partly depends on how one defines deliberation and participation. Mutz's definition of deliberation as ?hearing the other side? or ?cross-cutting exposure? is narrower than a minimal conception of deliberation with which deliberative democrats could agree. First, a minimal conception of deliberation would have to revolve around the principle of a reasoned exchange of arguments, as opposed to mere exposure to dissenting views. (...) Second, Mutz's almost exclusive focus on participation as partisan activism gives the impression of an essential tension between participation and deliberation. But another form of civic participation, which I call ?critical-deliberative involvement,? is perfectly compatible with the incentives for reasoned exchange of arguments with others. We should thus encourage people to participate in politics in ways that engage their reasoning faculty, not just their party loyalty. This also requires teaching people how to disagree constructively. (shrink)

Having defended the usefulness of our definition of reasoning, we stress that reasoning is not only for convincing but also for evaluating arguments, and that as such it has an epistemic function. We defend the evidence supporting the theory against several challenges: People are good informal arguers, they reason better in groups, and they have a confirmation bias. Finally, we consider possible extensions, first in terms of process-level theories of reasoning, and second in the effects of reasoning outside the lab.

Typically, public discussions of questions of social import exhibit two important properties: they are influenced by conformity bias, and the influence of conformity is expressed via social networks. We examine how social learning on networks proceeds under the influence of conformity bias. In our model, heterogeneous agents express public opinions where those expressions are driven by the competing priorities of accuracy and of conformity to one’s peers. Agents learn, by Bayesian conditionalization, from private evidence from nature, and from the public (...) declarations of other agents. Our key findings are that networks that produce configurations of social relationships that sustain a diversity of opinions empower honest communication and reliable acquisition of true beliefs, and that the networks that do this best turn out to be those which are both less centralized and less connected.

Psychological and neuroscientific data suggest that a great deal, perhaps even most, of our reasoning turns out to be rationalizing. The reasons we give for our positions are seldom either the real reasons or the effective causes of why we have those positions. We are not as rational as we like to think. A second, no less disheartening observation is that while we may be very effective when it comes to giving reasons, we are not that good at getting reasons. (...) We are not as reasons-responsive as we like to think. Reasoning and argumentation are, on this view, charades without effect. This paper begins by identifying a range of theoretical responses to the idea that reasoning and argumentation have little casual role in our thoughts and actions, and, consequently, that humans are not the reasons-giving, reasons-responsive agents that we imagine ourselves to be. The responses fall into three categories: challenging the data and their interpretations; making peace with the loss of autonomy that is implied; and seeking ways to expand the causal footprint of reasoning and argumentation, e.g., by developing argumentative virtues. There are indeed possibilities for becoming more rational and more reasons-responsive, so the reports of our demise as the rational animal are greatly exaggerated. (shrink)

This paper argues that (a) civic constitutionalism is a cohesive body of scholarship (b) it offers a detailed challenge to Hélène Landemore’s account of how to fix democratic politics, while at the same time (c) suggesting how to blend compelling features of Landemore’s approach with a more traditionally-grounded approach (d) consequently, democratic theorists of all sorts should consider becoming civic constitutionalists.

El objetivo de este trabajo es proponer un concepto de agente crítico que dialogue con una práctica democrática deliberativa, considerando qué significa el acto de dar razones. Para tal efecto, en este trabajo se discute, primero, qué significaría ser crítico o tender hacia la criticidad tanto autorreferente como hacia terceros. Esta sección está apoyada principalmente con ideas provenientes de la teoría de la argumentación y de la lógica informal. En segundo término, se aborda el concepto de democracia deliberativa a la (...) luz de la sinergia conceptual que habría entre la participación -potencial- de un agente crítico en tal contexto sociopolítico. En esta sección se pasa revista a algunas de las ideas centrales de la teoría de la democracia deliberativa. Y en la tercera y última parte, se aborda el problema de dar y recibir razones discutiendo la propuesta semántica inferencialista de Brandom (2002, 2005) para observar de qué manera este acercamiento puede aportar a una teoría de la deliberación y a un concepto -y educación- de agente crítico. En las conclusiones se sintetizan las ideas principales y, además, se hace un contrapunto entre la noción de agencia, concepto que es importante en mi propuesta, y la noción de persona, concepto de especial valor en la teoría de la democracia deliberativa.

Theories of deliberative democracy maintain that outcomes of democratic deliberation are fairer than outcomes of mere aggregation of preferences. Theorists of impartial justice, especially Rawls and Sen, emphasize the role of deliberative processes for making just decisions. Democratic deliberation seems therefore to provide a model of impartial decision-making applicable in the real world. However, various types of cognitive and affective biases limit individual capacity to see things from others’ perspectives. In this paper, two strategies of enhancing impartiality in real world (...) decision-making are discussed. The first involves decision-making processes which detach decision-makers from their particular interests, whereas the second aims to enhance the quality of democratic deliberation and empathetic reasoning. We conclude that new forms of democratic deliberation may be necessary if we hold on to the aspiration of making decisions which are both democratic and impartial. (shrink)

The role of reasoning in our moral lives has been increasingly called into question by moral psychology. Not only are intuitions guiding many of our moral judgments and decisions, with reasoning only finding post-hoc rationalizations, but reasoning can sometimes play a negative role, by finding excuses for our moral violations. The observations fit well with the argumentative theory of reasoning (Mercier H, Sperber D, Behav Brain Sci, in press-b), which claims that reasoning evolved to find and evaluate arguments in dialogic (...) contexts. This theory explains the strong confirmation bias that reasoning displays when it produces arguments, which in turn explains its tendency to rationalize our decisions. But this theory also predicts that people should be able to evaluate arguments felicitously and that, as a result, people should reason better in groups, when they are confronted with other people’s arguments. Groups are able to converge on better moral judgments. It is argued that reasoning and argumentation play an important role in our everyday moral lives, and a defense of the value of reasoning for moral change is offered. (shrink)

In this paper, I argue for a _(pro tanto)_ _moral duty against dogmatism_: I argue that the _social costs_ of a disagreement can give those who are party to it added moral reasons to reconsider their controversial beliefs and (so) not to be dogmatic. In Sect. 1, I motivate the idea _that_ the social costs of disagreement may give rise to reasons to reconsider our beliefs by considering intuitive examples to that effect. I suggest that some of the stock intuitions (...) that epistemologists of disagreement have depended on to make their arguments are implicitly influenced by social costs that are salient to the disagreements in their cases. In Sect. 2, I respond to a _Practical Objection_ to my argument that political philosophers might be keen to press. According to this objection, the social costs of disagreement do not give rise to a moral duty against dogmatism because we can adequately address those costs just by compromising on how we _act on_ our beliefs in the context of the disagreement. In Sect. 3, I address a contrasting objection to the moral duty against dogmatism that might be pressed by epistemologists, which I term the _Truth Objection._ This objection points out that the social costs of disagreement do nothing to affect the strength of the _evidence _for or against one’s contentious beliefs, and so complains that those who reconsider their beliefs just on account of the social costs of disagreement ‘cave in’ to social pressure in a problematic way. In the course of addressing the Truth Objection, I more carefully explain _how_ the social costs of disagreement give rise to a moral duty against dogmatism by distinguishing between ‘truth-motivated’ and ‘truth-indifferent’ reasons for inquiry.

This paper argues in favor of the epistemic properties of inclusiveness in the context of democratic deliberative assemblies and derives the implications of this argument in terms of the epistemically superior mode of selection of representatives. The paper makes the general case that, all other things being equal and under some reasonable assumptions, more is smarter. When applied to deliberative assemblies of representatives, where there is an upper limit to the number of people that can be included in the group, (...) the argument translates into a defense of a specific selection mode of participants: random selection.

La democracia deliberativa establece el acuerdo racional como el fin de los procesos deliberativos. Sin embargo, estudios actuales muestran que en ciertas ocasiones la deliberación, lejos de producir el acuerdo, genera procesos de polarización. Una aproximación a este problema de la polarización de los procesos deliberativos ha sido desarrollada desde la neuroética por autores como Lakoff, Haidt o Hugo Mercier. Así, en este artículo pretendo, en primer lugar, abordar el enfoque de estos autores sobre la polarización. Esto permitirá extraer los (...) errores que pueda haber en sus planteamientos. Finalmente, desarrollaré una propuesta para corregir la polarización de los procesos deliberativos. (shrink)

During the course of life, it is common to make some decisions that prove to be correct. Some of these choices are made without a specific reason, but only out of habit or intuitively, while others are based on judgments and motivations. However, when we claim that a decision is “right”, what kind of judgment are we referring to? On the one hand, the term “right” (or “wrong”) often refers to abstract norms. Usually, truth and falsehood serve as criteria in (...) these cases. In such situations, judgments about what is “right” or “wrong” depend strictly on an accurate rational evaluation, which is instrumental in guiding individuals to undertake or avoid certain actions. On the other hand, there is a sense of justice that concerns ethics and values. In these circumstances, a decision is generally considered “right” if it is based on a criterion of judgment that allows individuals to make a decision freely, without being bound by an abstract norm, but rather by elaborating the choice as the realization of what they consider good and just. In this paper will examine and redefine the concept of “right choice”, acknowledging the above mentioned dual nature of its meaning. It will be argued there is a link between what abstract norms dictate to do, in order to reach a formally correct decision, and what, instead, depends on merely reasons and attitudes. This connection is indeed ensured by wise decisions. (shrink)

Who is the best moral reasoner, the judge or the legislator? The aim of this paper is to refine this question, by distinguishing between different metaethical assumptions. If the meta-ethical assumptions of arguers are incompatible or if their institutional goal is to establish some truth, there is no way of entering in a constructive argumentative activity. My claim is that only when arguers renounce any epistemic temptation and feel empathy with respect to others’ arguments, can institutions improve the quality of (...) their judicial and democratic arguments, and therefore gain authority.

Mercier and Sperber illuminate many aspects of reasoning and rationality, providing refreshing and thoughtful analysis and elegant and well‐researched illustrations. They make a good case that reasoning should be viewed as a type of intuition, rather than a separate cognitive process or system. Yet questions remain. In what sense, if any, is reasoning a “module?” What is the link between rationality within an individual and rationality defined through the interaction between individuals? Formal theories of rationality, from logic, probability theory and (...) game theory, while not the focus of Mercier and Sperber's book, may help clarify this latter question. (shrink)
