Starting from the sensuous perception of what is seen, an attempt is made at re-casting a Husserlian theory of constitution of the object of intuition, as one leaves the natural attitude through a transcendental method, by positing several theses so as to avoid the aporias of philosophical binary oppositions such as rationalism and empiri-cism, realism and idealism, logicism and psychologism, subjectivism and objectivism, transcendentalism and ontologism, metaphysics and positivism. Throughout fifty-five theses on constitution, the Husserlian proposal of continuously reforming philosophizing (...) by transcendental reduction is revisited, leaving the latter incomplete as new conversions are required by noetic-noematic correlations between world and consciousness.

I argue that scientific knowledge is collective knowledge, in a sense to be specified and defended. I first consider some existing proposals for construing collective knowledge and argue that they are unsatisfactory, at least for scientific knowledge as we encounter it in actual scientific practice. Then I introduce an alternative conception of collective knowledge, on which knowledge is collective if there is a strong form of mutual epistemic dependence among scientists, which makes it so that satisfaction of the justification condition (...) on knowledge ineliminably requires a collective. Next, I show how features of contemporary science support the conclusion that scientific knowledge is collective knowledge in this sense. Finally, I consider implications of my proposal and defend it against objections. (shrink)

This paper studies the Lockean thesis from the perspective of contemporary epistemic logic. The Lockean thesis states that belief can be defined as ‘sufficiently high degree of belief’. Its main problem is that it gives rise to a notion of belief which is not closed under conjunction. This problem is typical for classical epistemic logic: it is single-agent and static. I argue that from the perspective of contemporary epistemic logic, the Lockean thesis fares much better. I briefly mention that it (...) can successfully be extended from single-agent to multi-agent settings. More importantly, I show that accepting the Lockean thesis (and a more sophisticated version for conditional beliefs) leads to a significant and unexpected unification in the dynamic behavior of (conditional) belief and high (conditional) probability with respect to public announcements. This constitutes a methodological argument in favor of the Lockean thesis. Furthermore, if one accepts Baltag’s Erlangen program for epistemology, this technical observation has even stronger philosophical implications: because belief and high probability display the same dynamic behavior, it is plausible that they are indeed one and the same epistemic notion.

This paper motivates an account of knowledge as a social kind, following a cue by Edward Craig, which captures two major insights behind social and feminist epistemologies, in particular our epistemic interdependence concerning knowledge and the role of social regulative practices in understanding knowledge.

As a belief source, testimony has long been held by theorists of the mind to play a deeply important role in human cognition. It is unclear, however, just why testimony has been afforded such cognitive importance. We distinguish three suggestions on the matter: the number claim, which takes testimony’s cognitive importance to be a function of the number of beliefs it typically yields, relative to other belief sources; the reliability claim, which ties the importance of testimony to its relative truth-conduciveness; (...) and the scope claim, according to which testimony’s importance is a function of its relative representational power, non-numerically conceived. After laying out these three suggestions, we go on to argue that there is little hope of grounding testimony’s cognitive importance in either the number claim or the reliability claim. We conclude with a tentative exploration of the basis and plausibility of the scope claim. (shrink)

This paper is about the alethic aspect of epistemic rationality. The most common approaches to this aspect are either normative (what a reasoner ought to/may believe?) or evaluative (how rational is a reasoner?), where the evaluative approaches are usually comparative (one reasoner is assessed compared to another). These approaches often present problems with blindspots. For example, ought a reasoner to believe a currently true blindspot? Is she permitted to? Consequently, these approaches often fail in describing a situation of alethic maximality, (...) where a reasoner fulfills all the alethic norms and could be used as a standard of rationality (as they are, in fact, used in some of these approaches). I propose a function α, which accepts a set of beliefs as inputand returns a numeric alethic value. Then I use this function to define a notion of alethic maximality that is satisfiable by finite reasoners (reasoners with cognitive limitations) and does not present problems with blindspots. Function α may also be used in alethic norms and evaluation methods (comparative and non-comparative) that may be applied to finite reasoners and do not present problems with blindspots. A result of this investigation isthat the project of providing purely alethic norms is defective. The use of function α also sheds light on important epistemological issues, such as the lottery and the preface paradoxes, and the principles of clutter avoidance and reflection. (shrink)

I propose the notion of ‘epistemic sanity’, a property of parsimony between the holding of true but not false beliefs and the consideration of our cognitive limitations. Where ‘alethic value’ is the epistemic value of holding true but not false beliefs, the ‘alethic potential’ of an agent is the amount of extra alethic value that she is expected to achieve, given her current environment, beliefs, and reasoning skills. Epistemic sanity would be related to the holding of (true or false) beliefs (...) that increase the agent's alethic potential (relevant beliefs) but not of beliefs that decrease it (this is related to cognitive parsimony). Suspension of judgment, forgetting, and clutter avoidance are the main contributors to an agent's epistemic sanity, where this paper focuses on suspension. I argue that rational suspension favors the holding of true and relevant beliefs, which is not the case for the extremes of opinionation (no suspension) and skepticism (general suspension). In the absence of evidence, opinionated agents are often forced to rely on principles such as the principle of indifference, but suspension dominates indifference in terms of alethic value in some conditions. A rational agent would only find it beneficial to adopt skepticism if she considers herself to be an anti-expert about her entire agenda, but then ‘flipping’ beliefs maximizes expected alethic value in relation to skepticism. The study of epistemic sanity results in an ‘impure’ veritism, which can deal with some limitations of veritism (e.g., explaining the existence of false but relevant beliefs). (shrink)

Kuhn’s “essential tension” between conservative and innovative imperatives in enquiry has an empirical analogue—between the potential benefits of collectivization of enquiry and the social dynamic impediments to effective sharing of information and insights in collective settings. A range of empirical materials from social psychology and organization theory are considered which bear on the issue of balancing these opposing forces and an institution is described in which they are balanced in a way which is appropriate for collective knowledge production.

It has been commonplace in epistemology since its inception to idealize away from computational resource constraints, i.e., from the constraints of time and memory. One thought is that a kind of ideal rationality can be specified that ignores the constraints imposed by limited time and memory, and that actual cognitive performance can be seen as an interaction between the norms of ideal rationality and the practicalities of time and memory limitations. But a cornerstone of naturalistic epistemology is that normative assessment (...) is constrained by capacities: you cannot require someone to do something they cannot or, as it is usually put, ought implies can. This much we take to be uncontroversial. We argue that differences in architectures, goals and resources imply substantial differences in capacity, and that some of these differences are ineliminable. It follows that some differences in goals and architectural and computational resources matter at the normative level: they constrain what principles of normative epistemology can be used to describe and prescribe their behavior. As a result, we can expect there to be important epistemic differences between the way brains, individuals, and science work. (shrink)

This paper attempts to provide a remedy to a surprising lacuna in the current discussion in the epistemology of expertise, namely the lack of a theory accounting for the epistemic authority of collective agents. After introducing a service conception of epistemic authority based on Alvin Goldman’s account of a cognitive expert, I argue that this service conception is well suited to account for the epistemic authority of collective bodies on a non-summativist perspective, and I show in detail how the defining (...) requirements of an expert can apply to epistemic groups.

This paper uses the economic crisis of 2008 as a case study to examine the explanatory validity of collective mental representations. Distinguished economists such as Paul Krugman and Joseph Stiglitz attribute collective beliefs, desires, intentions, and emotions to organizations such as banks and governments. I argue that the most plausible interpretation of these attributions is that they are metaphorical pointers to a complex of multilevel social, psychological, and neural mechanisms. This interpretation also applies to collective knowledge in science: scientific communities (...) do not literally have collective representations, but social mechanisms do make important contributions to scientific knowledge.

Our approach to the epistemology of post-truth is based on the idea that to fully comprehend any post-truth, going back to its origins (i.e., to the moment in which some faulty interpretations start to spread) can be not only relevant but illuminating.One of the most renowned cases of post-truth concerns vaccines and their alleged relationship with autism. It all started in 1998, when The Lancet published a study suggesting a link between the measles, mumps, and rubella vaccine and some symptoms (...) of autism. The case is relevant both because it is at the origins of contemporary anti-vaccinism and because it took twelve years to fully disprove what in 1998 was presented as a scientific truth: this means that the boundary between truth and falsehood has been blurred for a long period of time.For this purpose, we have applied the semiotic methodology to 20 articles from The Independent, 20 from The Telegraph, 20 from The Guardian, and 20 from The Daily Mail, published between 1998 and 2010. Unexpectedly, many elements that can be seen as ‘post-truth seeds’, such as conspiracy theories and the joint presentation of multiple truths, have been found even in the most scientifically accurate newspapers.

O objetivo central desse artigo é apresentar uma posição cognitivista e contextualista no que diz respeito à atribuição de significado dos conceitos normativos de ‘dever’, ‘correto’ e ‘errado’ usados em sentenças cotidianas. Argumentaremos que esses conceitos normativos são melhor compreendidos em termos de razões para agir. Após várias distinções iniciais de esclarecimentos, apontaremos para uma estratégia naturalizada da normatividade não reducionista, bem como para um procedimento de isolamento visando a justificação dos juízos normativos. Por fim, defenderemos que a atribuição de (...) verdade aos juízos normativos se dará em um âmbito de convergência prática. (shrink)

There is a great deal of academic literature, much of it coming from the social sciences and from social epistemology, which presents itself as addressing a very general problem: the problem of excessive falsehood. Falsehood comes in two general forms: false statements and false beliefs. Of course, falsehood, in both these forms, has always been with us, but it is often supposed to be on the rise. I will argue that there is no new or growing problem of excessive falsehood (...) (variously referred to as the problem of “misinformation” or “fake news”). Furthermore, we should reject the very idea that falsehood as such is a problem, and hence we should reject the idea of coming up with public policy responses to this so-called problem. I argue that the idea that falsehood is a problem is a natural consequence of the idea that it is virtuous to love truth and hate falsehood. I argue that, although there are several virtues related to truth (such as the intellectual virtue of curiosity and the moral virtue of honesty), a love of truth and hatred of falsehood are not themselves virtues.

Philosophers agree that an important part of our knowledge is acquired via testimony. One of the main objectives of social epistemology is therefore to specify the conditions under which a hearer is justified in accepting a proposition stated by a source. Non-reductionists, who think that testimony could be considered as an a priori source of knowledge, as well as reductionists, who think that another type of justification has to be added to testimony, share a common conception about children development. Non-reductionists (...) believe that infants and children are fundamentally gullible and their gullibility could be seen as an example for justifying testimony, while reductionists believe that this gullibility is merely an exception that should be taken into account. The objective of this paper is to review contemporary literature in developmental psychology providing empirical grounds likely to clarify this philosophical debate. What emerges from current research is a more elaborated vision of children’s attitude toward testimony. Even at a very young age, children do not blindly swallow information coming from testimony; doubtful or contradictory information is automatically screened by their cognitive system. Even if they are unable to give positive reasons for the acceptance of a given testimony, young children are not gullible. Such empirical findings tend to call into question the radical opposition between reductionism and non-reductionism. (shrink)

There is overwhelming agreement amongst naturalists that a naturalistic ontology should not allow for the possibility of supernatural entities. I argue, against this prevailing consensus, that naturalists have no proper basis to oppose the existence of supernatural entities. Naturalism is characterized, following Leiter and Rea, as a position which involves a primary commitment to scientific methodology and it is argued that any naturalistic ontological commitments must be compatible with this primary commitment. It is further argued that properly applied scientific method (...) has warranted the acceptance of the existence of supernatural entities in the past and that it is plausible to think that it will do so again in the future. So naturalists should allow for the possibility of supernatural entities. (shrink)

This article elaborates a conceptual framework to systematize the epistemic evaluation of social systems. This framework can be used to structure an evaluation or to characterize and assess existing ones. The article then uses the framework to assess four representative evaluations of think tanks. This meta-evaluation exemplifies how the framework can play its structuring role. It also leads us to general conclusions about the existing evaluations of think tanks. Most importantly, by focusing on the organizational level, existing evaluations miss factors (...) that are situated at the network and ecosystemic levels and that significantly determine how well think tanks serve society in producing and disseminating knowledge relevant to public policy. This conclusion suggests the need for epistemic evaluations of think tank ecosystems. (shrink)

On the assumption that genuinely normative demands concern things connected in some way to our agency, i.e. what we exercise in doing things with or for reasons, epistemologists face an important question: are there genuine epistemic norms governing belief, and if so where in the vicinity of belief are we to find the requisite cognitive agency? Extant accounts of cognitive agency tend to focus on belief itself or the event of belief-formation to answer this question, to the exclusion of the (...) activity of maintaining a system of beliefs. This paper argues that a full account of epistemic normativity will need to make sense of this activity as a core locus of cognitive agency. This idea is used to motivate the conclusion that one important and often overlooked kind of epistemic norms is the kind of norms governing the various cognitive activities by which we check, sustain, and adjust our belief systems.

Following Mr. Bixby and some other 19th century scientist-philosophers such as Claude Bernard, relevant scientific actions should, as a matter of primary importance, be explained with reference to the competence and not to the intentions of those involved. The background is a reliabilist virtue approach - a widespread tendency in 19th century epistemology and philosophy of science. Bixby's approach includes a critique of some constructivist arguments and establishes a mutually supportive connection to conceptions of scientific progress.

In this paper, we investigate the problem of truth approximation via belief merging, i.e., we ask whether, and under what conditions, a group of inquirers merging together their beliefs makes progress toward the truth about the underlying domain. We answer this question by proving some formal results on how belief merging operators perform with respect to the task of truth approximation, construed as increasing verisimilitude or truthlikeness. Our results shed new light on the issue of how rational (dis)agreement affects the (...) inquirers’ quest for truth. In particular, they vindicate the intuition that scientific inquiry, and rational discussion in general, benefits from some heterogeneity in opinion and interaction among different viewpoints. The links between our approach and related analyses of truth tracking, judgment aggregation, and opinion dynamics, are also highlighted. (shrink)

This article proposes a cost-benefit analysis of argumentation, with the aim of highlighting the strategic considerations that govern the agent's decision to argue or not. In spite of its paramount importance, the topic of argumentative decision-making has not received substantial attention in argumentation theories so far. We offer an explanation for this lack of consideration and propose a tripartite taxonomy and detailed description of the strategic reasons considered by arguers in their decision-making: benefits, costs, and dangers. We insist that the (...) implications of acknowledging the strategic dimension of arguing are far-reaching, including promising insights on how to develop better argumentation technologies. (shrink)

Virtue perspectivism is a bi-level epistemology according to which there are two grades of knowledge: animal and reflective. The exercise of reliable competences suffices to give us animal knowledge; but we can then use these same competences to gain a second-order assuring perspective, one through which we may appreciate those faculties as reliable and in doing so place our first-order knowledge in a competent second-order perspective. Virtue perspectivism has considerable theoretical power, especially when it comes to vindicating our external world (...) knowledge against threats of scepticism and regress. Prominent critics, however, doubt whether the view ultimately hangs together without succumbing to vicious circularity. In this paper, I am going to focus on circularity-based criticisms of virtue perspectivism raised in various places by Barry Stroud, Baron Reed and Richard Fumerton, and I will argue that virtue perspectivism can ultimately withstand each of them.

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

Reductive intellectualists (e.g., Stanley & Williamson 2001; Stanley 2011a; 2011b; Brogaard 2008; 2009; 2011) hold that knowledge-how is a kind of knowledge-that. If this thesis is correct, then we should expect the defeasibility conditions for knowledge-how and knowledge-that to be uniform—viz., that the mechanisms of epistemic defeat which undermine propositional knowledge will be equally capable of imperilling knowledge-how. The goal of this paper is twofold: first, against intellectualism, we will show that knowledge-how is in fact resilient to being undermined by (...) the very kinds of traditional (propositional) epistemic defeaters which clearly defeat the items of propositional knowledge which intellectualists identify with knowledge-how. Second, we aim to fill an important lacuna in the contemporary debate, which is to develop an alternative way in which epistemic defeat for knowledge-how could be modelled within an anti-intellectualist framework.

While openmindedness is often cited as a paradigmatic example of an intellectual virtue, the connection between openmindedness and truth is tenuous. Several strategies for reconciling this tension are considered, and each is shown to fail; it is thus claimed that openmindedness, when intellectually virtuous, bears no interesting essential connection to truth. In the final section, the implication of this result is assessed in the wider context of debates about epistemic value.

This paper argues that a set of questioning attitudes are among the foundations of human and animal minds. While both verbal questioning and states of curiosity are generally explained in terms of metacognitive desires for knowledge or true belief, I argue that each is better explained by a prelinguistic sui generis type of mental attitude of questioning. I review a range of considerations in support of such a proposal and improve on previous characterizations of the nature of these attitudes. I (...) then broaden their explanatory scope to include a number of forms of exploratory search. The paper has three main goals: to characterize the nature of the questioning attitudes, outlining their causal role and type of content; to argue that they are fundamental components of the mind, being widespread among animals and not constructed during ontogeny out of other attitudes; and to suggest that they explain a great deal more behavior than one might think.

The COVID-19 pandemic has been accompanied by an “infodemic” of misinformation and conspiracy theory. This article points to three explanatory factors: the challenge of forming accurate beliefs when overwhelmed with information, an implausibly individualistic conception of epistemic virtue, and an adversarial information environment that suborns epistemic dependence. Normally we cope with the problems of informational excess by relying on other people, including sociotechnical systems that mediate testimony and evidence. But when we attempt to engage in epistemic “superheroics” - withholding trust (...) from others and trying to figure it all out for ourselves – these can malfunction in ways that make us vulnerable to forming irrational beliefs. Some epistemic systems are prone to coalescing audiences around false conspiracy theories. This analysis affords a new perspective on philosophical efforts to understand conspiracy theories and other epistemic projects prone to collective irrationality. (shrink)

This article argues that political realists have at least two strategies to provide distinctively political normative judgements that have nothing to do with morality. The first ground is instrumental normativity, which states that if we believe that something is a necessary means to a goal we have, we have a reason to do it. In politics, certain means are required by any ends we may intend to pursue. The second ground is epistemic normativity, stating that if something is true, this (...) gives us a reason to believe it. In politics, there are certain empirical regularities that ought to be acknowledged for what they are. Both sources are flawed. Instrumental normativity only requires coherence between attitudes and beliefs, and one can hang on to false beliefs to preserve attitudes incompatible with reality. I may desire to eschew power relations, and accordingly I may imagine politics to be like a camping trip. Epistemic normativity, on the other hand, operates critically, striking down existing normative claims. It shows us that politics is nothing like a camping trip, but it doesn’t tell us what we should do about it. We conclude by showing that if the two are taken together, they remedy each other’s flaws.

Ethotic arguments, such as arguments from expert opinion and ad hominem arguments, play an important role in communication practice. In this paper, we argue that there is another type of reasoning from ethos, in which people argue about actions in the world. These subspecies of ethotic arguments are very common in public debates: societies are involved in heated disputes about what should be done with monuments of historical figures such as Stalin or Colston: Should we demolish the building they funded? (...) Should we revere their statues? Should the street named after them be renamed?; and the general public vividly argue about what should be done with the legacy of producers, directors and actors in debates of the #MeToo movement: Should their new movies be distributed? Should their scenes be deleted from motion pictures? Should their stars from the Hollywood Walk of Fame be removed? Many arguments in these debates boil down to the character of the public figures: He was a slave trader!—But he is a part of our history; He harassed a young girl!—But he is an important actor. The reasoning step here is legitimised by the association between a person and an extra-linguistic object: the association between a historical figure and their statue or between an actor and their movie. The nature of this association is explained in the paper using Peirce’s theory of signs. We propose to extend an existing approach to patterns of reasoning from ethos that will help us to shed new light on ethotic argumentation and open an avenue for a systematic account of these unexplored argument forms.

The belief norm of academic publishing states that researchers should believe certain claims they publish. The purpose of this paper is to defend the belief norm of academic publishing. In its defense, the advantages and disadvantages of the belief norm are evaluated for academic research and for the publication system. It is concluded that while the norm does not come without costs, academic research systemically benefits from the belief norm and that it should be counted among those that sustain the (...) practice of academic publishing.

It is widely accepted in epistemology that knowledge is factive, meaning that only truths can be known. We argue that this theory creates a skeptical challenge: because many of our beliefs are only approximately true, and therefore false, they do not count as knowledge. We consider several responses to this challenge and propose a new one. We propose easing the truth requirement on knowledge to allow approximately true, practically adequate representations to count as knowledge. In addition to addressing the skeptical (...) challenge, this view also coheres with several previous theoretical proposals in epistemology. (shrink)

Next SectionBiodefence, broadly understood as efforts to prevent or mitigate the damage of a bioterrorist attack, raises a number of ethical issues, from the allocation of scarce biomedical research and public health funds, to the use of coercion in quarantine and other containment measures in the event of an outbreak. In response to the US bioterrorist attacks following September 11, significant US policy decisions were made to spur scientific enquiry in the name of biodefence. These decisions led to a number (...) of critical institutional changes within the US federal government agencies governing scientific research. Subsequent science policy discussions have focused largely on ‘the dual use problem’: how to preserve the openness of scientific research while preventing research undertaken for the prevention or mitigation of biological threats from third parties. We join others in shifting the ethical debate over biodefence away from a simple framing of the problem as one of dual use, by demonstrating how a dual use framing distorts the debate about bioterrorism and truncates discussion of the moral issues. We offer an alternative framing rooted in social epistemology and institutional design theory, arguing that the ethical and policy debates regarding ‘dual use’ biomedical research ought to be reframed as a larger optimisation problem across a plurality of values including, among others: (1) the production of scientific knowledge; (2) the protection of human and animal subjects; (3) the promotion and protection of public health (national and global); (4) freedom of scientific enquiry; and (5) the constraint of government power.

Suppose an inquiring group wants to let a certain view stand as the group's view. But there’s a problem: the individuals in that group do not initially all agree with one another about what the correct view is. What should the group do, given that it wants to settle on a single answer, in the face of this kind of intragroup disagreement? Should the group members deliberate and exchange evidence and then take a vote? Or, given the well-known ways that (...) evidence exchange can go wrong, e.g., by exacerbating pre-existing biases, compromising the independence of individual judgments, etc., should the group simply take a vote without deliberating at all? While this question has multiple dimensions to it—including ethical and political dimensions—we approach the question through an epistemological lens. In particular, we investigate to what extent it is epistemically advantageous and disadvantageous that groups whose members disagree over some issue use deliberation in comparison to voting as a way to reach collective agreements. Extant approaches in the literature to this ‘deliberation versus voting’ comparison typically assume there is some univocal answer as to which group strategy is best, epistemically. We think this assumption is mistaken. We approach the deliberation versus voting question from a pluralist perspective, in that we hold that a group’s collective endeavor to solve an internal dispute can be aimed at different, albeit not necessarily incompatible, epistemic goals, namely the goals of truth, evidence, understanding, and epistemic justice. Different answers to our guiding question, we show, correspond with different epistemic goals. We conclude by exploring several ways to mitigate the potential epistemic disadvantages of solving intragroup disagreement by means of deliberation in relation to each epistemic goal. (shrink)

This essay discusses Elliott Sober’s Evidence and Evolution: The Logic Behind the Science. Valuable to both philosophers and biologists, Sober analyzes the testing of different kinds of evolutionary hypotheses about natural selection or phylogenetic history, including a thorough critique of intelligent design. Not at least because of a discussion of different schools of hypothesis testing (Bayesianism, likelihoodism, and frequentism), with Sober favoring a pluralism where different inference methods are appropriate in different empirical contexts, the book has lessons for philosophy of (...) science beyond its evolutionary focus. I criticize Sober for not including epistemic values and social aspects of scientific practice in his epistemological framework. (shrink)

A recurring objection confronting utilitarianism is that its dictates require information that lies beyond the bounds of human epistemic wherewithal. Utilitarians require reliable knowledge of the social consequences of various policies, and of people’s preferences and utilities. Agreeing partway with the sceptics, I concur that the general rules-of-thumb offered by social science do not provide sufficient justification for the utilitarian legislator to rationally recommend a particular political regime, such as liberalism. Actual data about human preference-structures and utilities is required to (...) bridge this evidentiary gap. I offer two arguments to support the availability of such information. First, I contend that ordinary human beings have a clear method of epistemic access to reliable information about commensurable preference-structures. Second, in an attempt to shift the onus of philosophic argument, I show that the utilitarian legislator’s requirements do not differ in kind from those implicitly called upon by the sceptical deontic liberal.

There is currently a lively debate about whether there are practical reasons for belief, epistemic reasons for belief, or both. I will argue that the intuitions on all sides can be fully accounted for by applying an independently motivated contextualist semantics for normative terms. Specifically, normative terms must be relativized to a goal. One possible goal is epistemic, such as believing truly and not believing falsely, while another possible goal is practical, such as satisfying desires, or maximizing value. I will (...) argue that we have practical reasons given the practical goal and epistemic reasons given the epistemic goal. Disagreement disappears when we make the context explicit. The result is an independently motivated version ofpluralism. (shrink)

A perennial problem in social epistemology is the problem of expert testimony, specifically expert testimony regarding scientific issues: for example, while it is important for me to know information pertaining to anthropogenic climate change, vaccine safety, Covid-19, etc., I may lack the scientific background required to determine whether the information I come across is, in fact, true. Without being able to evaluate the science itself, then, I need to find trustworthy expert testifiers to listen to. A major project in social (...) epistemology has thus become determining what the markers of trustworthiness are that laypersons can appeal to in order to identify and acquire information from expert testifiers. At the same time, the ways in which we acquire scientific information has changed significantly, with much of it nowadays being acquired in online environments. While much has been said about the potential pitfalls of seeking information online, little has been said about how the nature of seeking information online should make us think about the problem of expert testimony. Indeed, it seems to be an underlying assumption that good markers of trustworthiness apply equally well when seeking information from expert testifiers in online and offline environments alike, and that the new challenges and opportunities presented by online environments merely affects the methods by which we can acquire evidence of said trustworthiness. Here I argue that in making this assumption one risks failing to account for how unique features of the ways in which we acquire information online affect how we evaluate the trustworthiness of experts. Specifically, I argue for two main claims: first, that the nature of information-seeking online is such that the extent to which information is susceptible to manipulation is a dominant marker of trustworthiness; second, as a result, one will be more likely to seek out a particular kind of expert testifier in online environments, what I call a cooperative as opposed to preemptive expert. The result is that criteria for expert trustworthiness may look significantly different when acquiring information online as opposed to offline. (shrink)

Epistemic accounts of scientific collaboration usually assume that, one way or another, two heads really are more than twice better than one. We show that this hypothesis is unduly strong. We present a deliberately crude model with unfavorable hypotheses. We show that, even then, when the priority rule is applied, large differences in successfulness can emerge from small differences in efficiency, with sometimes increasing marginal returns. We emphasize that success is sensitive to the structure of competing communities. Our results suggest (...) that purely epistemic explanations of the efficiency of collaborations are less plausible but have much more powerful socioepistemic versions. (shrink)

What, if any, are the limits of human understanding? Epistemic pessimists, sobered by our humble evolutionary origins, have argued that some parts of the universe will forever remain beyond our ken. But what exactly does it mean to say that humans are ‘cognitively closed’ to some parts of the world, or that some problems will forever remain ‘mysteries’? In this paper we develop a richer conceptual toolbox for thinking about different forms and varieties of cognitive limitation, which are often conflated (...) by the so-called ‘new mysterians’. We distinguish between representational access and imaginative understanding, as well as between different modalities of cognitive limitation. Next, we look at tried-and-tested strategies for overcoming our innate cognitive limitations, drawing from the literature on distributed cognition and cognitive scaffolding’. This allows us to distinguish between the limits of bare brains vs. scaffolded brains. Most importantly, we argue that this panoply of mind-extension devices is combinatorial and open-ended. In the end, this allows us to turn the table on the mysterians: for every alleged ‘mystery’, they should demonstrate that no possible combination of mind extension devices will bring us any closer to a solution.

Gilbert (2000) examined the issue of collective intentionality in science. Her paper consisted of a conceptual analysis of the negative role of collective belief, consensus, and joint commitment in science, with a brief discussion of a case study investigated by Thagard (1998a, 1998b). I argue that Gilbert's concepts have to be refined to be empirically more relevant. Specifically, I distinguish between different kinds of joint commitments. I base my analysis on a close examination of Thagard's example, the discovery of Helicobacter (...) pylori, and two other historical cases involving the Copenhagen school of quantum mechanics and the Austrian school of economics. I also argue that it is difficult to fulfill the condition of common knowledge, even in Gilbert's weak sense. I conclude by raising serious doubts about the very possibility of a certain type of joint commitment, which I refer to as an implicit joint commitment. (shrink)

Dans cette contribution, j’examine la spécificité d’une perspective d’épistémologie sociale en théorie de l’argumentation en me livrant à une analyse critique de la théorie actuellement dominante dans ce champ, la pragma-dialectique de Franz van Eemeren. Cette perspective, d’inspiration interactionniste gricéenne, se réclame du « rationalisme critique », donc d’une perspective épistémologiquement « préservationniste » (au sens où elle préserverait l’idée de référence à des normes de la connaissance). Et pourtant, en faisant des normes du débat argumenté, y compris des normes (...) de la connaissance, de simples règles de « bonne conduite », elle témoigne, de facto, d’une position épistémologiquement « révisionniste ». Cette perspective manifeste, par ailleurs, une forme d’« expansionnisme » sociologique élémentaire, comme tel légitime si l’on considère qu’introduire deux sujets, c’est déjà introduire du social. La pragma-dialectique n’introduit pas de nouveaux sujets de connaissance sui generis, tels que les communautés épistémiques ou les institutions (ce qui serait pour Alvin Goldman le critère de l’expansionnisme, un critère à mon sens trop fort), mais comme il s’agit de rendre compte d’argumentations, elle doit envisager au moins deux interlocuteurs potentiels et donc dépasser le solipsisme épistémologique, une posture explicite chez Descartes et implicite dans la plupart des théories de la connaissance classiques, lesquelles font rarement réellement place à l’intersubjectivité. Malgré ses limites, la pragma-dialectique, par sa recherche de normes de la construction de la connaissance plus proches des processus effectifs ou naturels de la connaissance, pourrait constituer – épistémologiquement redressée – une contribution importante à une épistémologie sociale « naturalisée ».

The issue of knowing what it means for a group to have collective beliefs is being discussed more and more in contemporary philosophy of the social sciences and philosophy of mind. Margaret Gilbert’s reconsideration of Durkheim’s viewpoint in the framework of the plural subject’s account is one of the most famous. This has implications in the history and the sociology of science—as well asin the history and sociology of philosophy—although Gilbert only outlined them in the former fields and said nothing (...) about the latter. Symmetrically but independently, a historian of science, Mara Beller, has recently challenged Kuhn’s conception of the role of consensus in sciences in a brilliant analysis by carefully studying the history of Copenhagen School of Quantum Mechanics. Not only does she show the role of disagreement and controversies (doubting whether there was any collective belief characteristic in this group of physicists), but she even shakes up the very idea of individual beliefs. Each scientist (Heisenberg, Bohr, etc.) could be seen as divided into several selves. This paper contends that these two conceptions open important new horizons in several domains, especially if they are linked together. The paper assesses this claim in the light of empirical examples like the Vienna Circle, Copenhagen School, and, eventually, Cartesian philosophy. Key Words: plural subject • polyphony • collective briefs • Cartesian argumentation. (shrink)

Cet article est le résumé d’un cours donné à l’université de Trèves en 2010. Son but est de montrer que si la philosophie du comme si de Vaihinger a longtemps été négligée, c’est parce qu’elle a été prise pour une variante peu originale du pragmatisme de type jamesien. En réalité, Vaihinger, partant d’une lecture originale de la critique kantienne, inaugure le fictionalisme, fort différent du pragmatisme, et très vivant aujourd’hui comme courant de la philosophie analytique.
