The demands of rationality are linked both to our subjective normative perspective (given that rationality is a person-level concept) and to objective reasons or favoring relations (given that rationality is non-contingently authoritative for us). In this paper, I propose a new way of reconciling the tension between these two aspects: roughly, what rationality requires of us is having the attitudes that correspond to our take on reasons in the light of our evidence, but only if it is competent. I show (...) how this view can account for structural rationality on the assumption that intentions and beliefs as such involve competent perceptions of downstream reasons, and explore various implications of the account.

The Generality Problem is widely recognized to be a serious problem for reliabilist theories of justification. James R. Beebe's Statistical Solution is one of only a handful of attempted solutions that has garnered serious attention in the literature. In their recent response to Beebe, Julien Dutant and Erik J. Olsson successfully refute Beebe's Statistical Solution. This paper presents a New Statistical Solution that countenances Dutant and Olsson's objections, dodges the serious problems that trouble rival solutions, and retains the theoretical virtues (...) that made Beebe's solution so attractive in the first place. There indeed exists a principled, rigorous, conceptually sparse, and plausible solution to the Generality Problem: it is the New Statistical Solution. (shrink)

Process reliabilists hold that in order for a belief to be justified, it must result from a reliable cognitive process. They also hold that a belief can be basically justified: justified in this manner without having any justification to believe that belief is reliably produced. Fumerton (1995), Vogel (2000), and Cohen (2002) have objected that such basic justification leads to implausible easy justification by means of either epistemic closure principles or so-called track record arguments. I argue that once we carefully (...) distinguish closure principles from transmission principles, and epistemic consequences from epistemic preconditions, neither version of this objection succeeds.

According to Sosa, knowledge is apt belief, where a belief is apt when accurate because adroit. Sosa :465–475, 2010; Judgment and agency, Oxford University Press, Oxford, 2015) adds to his triple-A analysis of knowledge, a triple-S analysis of competence, where a complete competence combines its seat, shape and situation. Much of Sosa’s influential work assumes that epistemic agents are individuals who acquire knowledge when they hit the truth through exercising their own individual skills in appropriate shapes and situations. This paper (...) explores an extension of Sosa’s framework to a social setting in which groups constitute epistemic agents over and above their individual members. The claim is that groups can be ascribed knowledge in virtue of hitting the truth through exercising their competences in appropriate shapes and situations. While knowledge at the collective level may diverge from knowledge at the individual level, the competences of groups are nothing over and above the combined competences of their members. The ensuing view thus has implications for the debate over reduction and supervenience in collective epistemology. (shrink)

Empirical work on and common observation of the emotions tells us that our emotions sometimes key us to the presence of real and important reason-giving considerations without necessarily presenting that information to us in a way susceptible of conscious articulation and, sometimes, even despite our consciously held and internally justified judgment that the situation contains no such reasons. In this paper, I want to explore the implications of the fact that emotions show varying degrees of integration with our conscious agency—from (...) none at all to quite substantial—for our understanding of our rationality, and in particular for the traditional assumption that weakness of the will is necessarily irrational.

Evolutionary debunking arguments against religious beliefs move from the claim that religious beliefs are caused by off-track processes to the conclusion that said religious beliefs are unjustified and/or false. Prima facie, EDAs commit the genetic fallacy, unduly conflating the context of discovery and the context of justification. In this paper, we first consider whether EDAs necessarily commit the genetic fallacy, and if not, whether modified EDAs provide successful arguments against theism. Then, we critically evaluate more recent attempts to argue that (...) a more promiscuous evolutionary scepticism renders religious belief unjustified because, unlike commonsense and scientific beliefs, religious beliefs have no way out of such scepticism.

In her paper “Radical Externalism”, Amia Srinivasan argues that externalism about epistemic justification should be preferred to internalism by those who hold a “radical” worldview (according to which pernicious ideology distorts our evidence and belief‐forming processes). I share Srinivasan's radical worldview, but do not agree that externalism is the preferable approach in light of the worldview we share. Here I argue that cases informed by this worldview can intuitively support precisely the internalist view that Srinivasan challenges, offer two such cases, (...) and explain away the externalist‐friendly intuitions that Srinivasan's cases solicit. I then articulate and defend a “radical” internalism, arguing that internalists’ aversion to epistemic hubris and emphasis on subjecting one's beliefs to critical scrutiny are especially attractive in realistic cases involving multiple intersecting axes of oppression—that is, precisely the sort of case that permeates our social world. I also argue that externalism's lack of interest in action‐guiding principles leaves it with little to offer us in the fight against epistemic oppression. (shrink)

This paper is an exercise in intellectual history, an attempt to understand how a specific term—”informal logic”— came to be interpreted in so many different ways. I trace the emergence and development of “informal logic” to help explain the many different meanings, how they emerged and how they are related. This paper is also, to some degree, an account of a movement that developed outside the mainstream of philosophy, whose origins lie in a desire to make logic useful (echoing Dewey).

Contemporary memory sciences describe processes that are dynamic and constructive. This has led some philosophers to weaken the relationship between memory and epistemology; though remembering can give rise to epistemic success, it is not itself an epistemic success state. I argue that non-epistemic theories will not do; they provide neither necessary nor sufficient conditions for remembering that p. I also argue that the shortcomings of the causal theory are epistemic in nature. Consequently, a theory of remembering must account for both (...) its fundamentally epistemic nature and for its constructive and dynamic processes. (shrink)

The purpose of this paper is to motivate and defend a recognizable version of N. L. Wilson's "Principle of Charity" Doing so will involve: (1) distinguishing it fromthe significantly different versions of the Principle familiar through the work of Quine and Davidson; (2) showing that it is compatible with, among other things, both semantic externalism and "simulation" accounts of interpretation; and (3) explaining how it follows from plausible constraints relating to the connection between interpretation and self-interpretation. Finally, it will be (...) argued that Charity represents a type of "minimal individualism" that is closely tied to first person authority, and that endorsing Charity in our interpretations of others reflects a commitment to capturing, from the third-person starting point, their first-personal point of view.

We provide an analysis of the public's having warranted epistemic trust in science, that is, the conditions under which the public may be said to have well-placed trust in the scientists as providers of information. We distinguish between basic and enhanced epistemic trust in science and provide necessary conditions for both. We then present the controversy regarding the connection between autism and measles–mumps–rubella vaccination as a case study to illustrate our analysis. The realization of warranted epistemic public trust in science (...) requires various societal conditions, which we briefly introduce in the concluding section. (shrink)

Building, restoring and maintaining well-placed trust between scientists and the public is a difficult yet crucial social task requiring the successful cooperation of various social actors and institutions. Kitcher’s takes up this challenge in the context of liberal democratic societies by extending his ideal model of “well-ordered science” that he had originally formulated in his. However, Kitcher nowhere offers an explicit account of what it means for the public to invest epistemic trust in science. Yet in order to understand how (...) his extended model and its implementation in the actual world address the problem of trust as well as to evaluate it critically, an explicit account of epistemic public trust in science needs to be given first. In this article we first present such an account and then scrutinize his project of building public trust in science in light of it. We argue that even though Kitcher’s ideal model and his proposals for its implementation in the real world face a number of problems, they can be addressed with the resources of our account.

There are three widely held beliefs among epistemologists: (1) the goal of inquiry is truth or something that entails truth; (2) epistemology aims for a reflectively stable theory via reflective equilibrium; (3) epistemology is a kind of inquiry. I argue that accepting (1) and (2) entails denying (3). This is a problem especially for the philosophers (e.g. Duncan Pritchard and Alvin Goldman) who accept both (1) and (2), for in order to be consistent, they must reject (3). The tension is (...) not restricted to epistemology. A similar tension also exists in the area of moral philosophy. The tension can be generalized. If one believes that the goal of inquiry is truth or something that entails truth and that philosophy aims for a reflectively stable theory via reflective equilibrium, she must deny that philosophy is a kind of inquiry.

Epistemologists often appeal to the idea that a normative theory must provide useful, usable, guidance to argue for one normative epistemology over another. I argue that this is a mistake. Guidance considerations have no role to play in theory choice in epistemology. I show how this has implications for debates about the possibility and scope of epistemic dilemmas, the legitimacy of idealisation in Bayesian epistemology, uniqueness versus permissivism, sharp versus mushy credences, and internalism versus externalism.

Epistemic closure has been a central issue in epistemology over the last forty years. According to versions of the relevant alternatives and subjunctivist theories of knowledge, epistemic closure can fail: an agent who knows some propositions can fail to know a logical consequence of those propositions, even if the agent explicitly believes the consequence (having “competently deduced” it from the known propositions). In this sense, the claim that epistemic closure can fail must be distinguished from the fact that agents do (...) not always believe, let alone know, the consequences of what they know—a fact that raises the “problem of logical omniscience” that has been central in epistemic logic. This paper, part I of II, is a study of epistemic closure from the perspective of epistemic logic. First, I introduce models for epistemic logic, based on Lewis’s models for counterfactuals, that correspond closely to the pictures of the relevant alternatives and subjunctivist theories of knowledge in epistemology. Second, I give an exact characterization of the closure properties of knowledge according to these theories, as formalized. Finally, I consider the relation between closure and higher-order knowledge. The philosophical repercussions of these results and results from part II, which prompt a reassessment of the issue of closure in epistemology, are discussed further in companion papers. As a contribution to modal logic, this paper demonstrates an alternative approach to proving modal completeness theorems, without the standard canonical model construction. By “modal decomposition” I obtain completeness and other results for two non-normal modal logics with respect to new semantics. One of these logics, dubbed the logic of ranked relevant alternatives, appears not to have been previously identified in the modal logic literature. More broadly, the paper presents epistemology as a rich area for logical study. (shrink)

The inductive argument from the falsity of most past scientific theories (more than 100 years old) to the falsity of most present ones is defensible, I argue, if it is modified to account for the degrees of theoreticity or observationality in such theories, and the extent to which they are hedged. The case of descriptive astronomy is examined to show that most of the true theories of the 1890s were high in observationality and/or significantly hedged. The false theories of that (...) period, however, were not even approximately true. Apparently, scientists are more interested in supplanting theories with improved observations than in producing true theories. (shrink)

Selim Berker argues that epistemic consequentialism is pervasive in epistemology and that epistemic consequentialism is structurally flawed. is incorrect, however. I distinguish between epistemic consequentialism and epistemic instrumentalism and argue that most putative consequentialists should be considered instrumentalists. I also identify the structural problem of epistemic consequentialism Berker attempts to pinpoint and show that epistemic instrumentalism does not have the consequentialist problem.

According to the safety condition, a subject knows that p only if she would believe that p only if p was true. The safety condition has been a very popular necessary condition for knowledge of late. However, it is well documented that the safety condition is trivially satisfied in cases where the subject believes in a necessary truth. This is for the simple reason that a necessary truth is true in all possible worlds, and therefore it is true in all (...) possible worlds where it is believed. But clearly, all beliefs concerning necessary truths do not amount to knowledge. The safety theorists have attempted to deal with the problem caused by necessary truths by restricting the safety condition to purely contingent truths and by globalizing the safety condition to a set of propositions. Both of these solutions are problematic. The principal aim of this paper is to develop a version of the safety condition that is able to deal with cases featuring necessary truths. (shrink)

Might there be extended cognition and thereby extended minds? Rightly, that possibility is being investigated at present by philosophers of mind. Should epistemologists share that spirit, by inquiring into the possibility of extended knowing and thereby of extended knowers? Indeed so, I argue. The key to this shift of emphasis will be an epistemologically improved understanding of the implications of epistemic externalism.

We propose an approach to epistemic justification that incorporates elements of both reliabilism and evidentialism, while also transforming these elements in significant ways. After briefly describing and motivating the non-standard version of reliabilism that Henderson and Horgan call “transglobal” reliabilism, we harness some of Henderson and Horgan’s conceptual machinery to provide a non-reliabilist account of propositional justification (i.e., evidential support). We then invoke this account, together with the notion of a transglobally reliable belief-forming process, to give an account of doxastic (...) justification. (shrink)

Reliablists have argued that the important evaluative epistemic concept of being justified in holding a belief, at least to the extent that that concept is associated with knowledge, is best understood as concerned with the objective appropriateness of the processes by which a given belief is generated and sustained. In particular, they hold that a belief is justified only when it is fostered by processes that are reliable (at least minimally so) in the believer’s actual world.[1] Of course, reliablists typically (...) recognize other concepts of justification--typically subjective notions--which are given a noncompeting sort of epistemic legitimacy. However, they have tended to focus on the epistemically central notion of "strong justification," and have come to settle on this familiar reliablist analysis, supposing that it pretty much exhausts what there is to say about "objective justification.". (shrink)

Some hold that beliefs arising out of certain sources such as perceptual experience enjoy a kind of entitlement—as one is entitled to believe what is thereby presented as true, at least unless further evidence undermines that entitlement. This is commonly understood to require that default epistemic entitlement is a non-evidential kind of epistemic warrant. Our project here is to challenge this common, non-evidential, conception of epistemic entitlement. We will argue that although there are indeed basic beliefs with default entitlement status, (...) typically the kind of default entitlement they possess is primarily a matter of the evidential support that accrues to them, both synchronically and diachronically, from wider mental states beyond the specific sensory-perceptual experiences that spawn them. We will call this status evidentially embedded epistemic entitlement—as distinct from entitlement as commonly understood in the literature, which we will call evidentially insular. Epistemic entitlement normally is characterized in the manner set forth in the first paragraph above, viz., as a form of default epistemic warrant that a given belief possesses independently of any other beliefs. We suggest that not all evidential support is managed at the level of belief. Thus, leaves room for the possibility of an epistemically embedded kind of entitlement. Here we develop the needed conception of entitlement drawing on Henderson and Horgan’s ideas of a kind of “iceberg epistemology.”. (shrink)

Familiar accounts have it that one explains thoughts or actions by showing them to be rational. It is common to find that the standards of rationality presupposed in these accounts are drawn from what would be thought to be aprioristic sources. I advance an argument to show this must be mistaken. But, recent work in epistemology and on rationality takes a less aprioristic approach to such standards. Does the new (psychological or cognitive scientific) realism in accounts of rationality itself significantly (...) improve the prospects for unproblematic forms of rationalizing explanation? Do earlier misgivings about rationalizing explanation ring hollow when the rationality to be attributed is "naturalized"? Answer: while explanation in terms of naturalized rationality would be free of one fatal flaw possessed by explanation in terms of rationality understood in the traditional fashion, it would yet have parallel flaws.

Addressing Walter Hopp’s original application of the distinction between agent-fallibility and method-fallibility to phenomenological inquiry concerning epistemic justification, I question whether these are the only two forms of fallibility that are useful or whether there are not also others that are needed. In doing so, I draw my inspiration from Husserl, who in the beginnings of his phenomenological investigations struggled with the distinction between noetic and noematic analyses. For example, in the Preface to the Second Edition of the Logical Investigations (...) he criticizes the First Investigation as having been “one-sidedly” noetically directed and as having thus neglected the noematic aspects of meaning (XVIII 13–14). Also, in an addendum to the Fifth Investigation he notes that in the transition from the First Edition to the Second he has learned to broaden the concept of “phenomenological content” to include not only the “real” ( reell ) contents (noetic, subjective) of consciousness but also the “intentional” (noematic, objective) (XIX/1 411). The fact that, in gradually moving from consciousness (noesis) to what consciousness is of (noema), Husserl struggled with this distinction is an indication of the immensity of the perplexing problems and potential solutions that Hopp has led the phenomenology of knowledge into by introducing his useful notions of agent-fallibility and method-fallibility. Like Husserl, he has focused mainly and mostly on the noetic issues; like Husserl as well, I will try to move step by step from the noetic area into the noematic. I conclude that Hopp’s approach has the potential to become seminal. (shrink)

John Hawthorne’s marvelous book contains a wealth of arguments and insights based on an impressive knowledge and understanding of contemporary discussion. We can address only a small aspect of the topic. In particular, we will offer our own answers to two questions about knowledge that he discusses.

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)

The relationship between economics and the philosophy of natural science has changed substantially during the last few years. What was once exclusively a one-way relationship from philosophy to economics now seems to be much closer to bilateral exchange. The purpose of this paper is to examine this new relationship. First, I document the change. Second, I examine the situation within contemporary philosophy of science in order to explain why economics might have its current appeal. Third, I consider some of the (...) issues that might jeopardize the success of this philosophical project. (shrink)

Does epistemic justification aim at truth? The vast majority of epistemologists instinctively answer 'Yes'; it's the textbook response. Joseph Cruz and John Pollock surprisingly say no. In 'The Chimerical Appeal of Epistemic Externalism' they argue that justification bears no interesting connection to truth; justification does not even aim at truth. 'Truth is not a very interesting part of our best understanding' of justification (C&P 2004, 137); it has no 'connection to the truth.' A 'truth-aimed ... epistemology is not entitled to (...) carry the day' (C&P 2004, 138, emphasis added).Pollock and Cruz's argument for this surprising conclusion is of general interest for it is 'out of step with a very common view on the ..

This paper argues that there are powerful similarities between cognitive development in children and scientific theory change. These similarities are best explained by postulating an underlying abstract set of rules and representations that underwrite both types of cognitive abilities. In fact, science may be successful largely because it exploits powerful and flexible cognitive devices that were designed by evolution to facilitate learning in young children. Both science and cognitive development involve abstract, coherent systems of entities and rules, theories. In both (...) cases, theories provide predictions, explanations, and interpretations. In both, theories change in characteristic ways in response to counterevidence. These ideas are illustrated by an account of children's developing understanding of the mind. (shrink)

In this paper we give reasons to think that reflective epistemic subjects cannot possess mere animal knowledge. To do so we bring together literature on defeat and higher-order evidence with literature on the distinction between animal knowledge and reflective knowledge. We then defend our argument from a series of possible objections.

Many epistemologists agree that even very young children sometimes acquire knowledge through testimony. In this paper I address two challenges facing this view. The first (building on a point made in Lackey (2005)) is the defeater challenge, which is to square the hypothesis that very young children acquire testimonial knowledge with the fact that children (whose cognitive immaturity prevents them from having or appreciating reasons) cannot be said to satisfy the No‐Defeaters condition on knowledge. The second is the extension challenge, (...) which is to give a motivated, extensionally‐adequate account of the conditions on testimonial knowledge in early childhood. Neither challenge can be met merely by endorsing externalism about knowledge; but we can meet both by reconceiving the process that eventuates in the child’s consumption of testimony. My central thesis is that this process should be seen as implicating features of the child’s social environment. The result is a novel anti‐individualistic externalism about knowledge. (shrink)

Epistemology has had a strongly individualist orientation, at least since Descartes. Knowledge, for Descartes, starts with the fact of one’s own thinking and with oneself as subject of that thinking. Whatever else can be known, it must be known by inference from one’s own mental contents. Achieving such knowledge is an individual, rather than a collective, enterprise. Descartes’s successors largely followed this lead, so the history of epistemology, down to our own time, has been a predominantly individualist affair.

Social epistemology is a many-splendored subject. Different theorists adopt different approaches and the options are quite diverse, often orthogonal to one another. The approach I favor is to examine social practices in terms of their impact on knowledge acquisition . This has at least two virtues: it displays continuity with traditional epistemology, which historically focuses on knowledge, and it intersects with the concerns of practical life, which are pervasively affected by what people know or don't know. In making this choice, (...) I am not blind to the allure of alternative approaches. In this paper I explain and motivate the knowledge-centered approach by contrasting it with a newly emerging alternative that has a definite appeal of its own. According to this alternative, the chief dimension of social epistemological interest would be rationality rather than knowledge. (shrink)

There are several different questions associated with the study of folk psychology: what is the nature of our commonsense concepts of mental states?, how do we attribute mental states, to ourselves and to other people?, and how do we acquire our concepts and skills at mental-state attribution?Three general approaches to these questions are examined and assessed: theory theory, simulation theory, and rationality theory. A preliminary problem is to define each of these approaches. Alternative definitions are explored, centering on which questions (...) each approach tries to answer and how it answers them. For example, simulation theorists substantially agree on the answer to question but not on the answer to question. The paper then turns to some serious problems facing both rationality theory and theory theory.Rationality theory is faulted for its inadequate treatment of question and for its implausible answers to question. Theory theory is faulted for the problems it encounters in explaining first-person attribution, and for its treatment of attributed reasoning about change. Turning to simulation theory, the paper argues against Gordon’s “ascent routine” account of first-person attribution and in favor of an inner detection account. Finally, the paper addresses the question of the contents of our mental-state concepts. How do these concepts incorporate both behavioral features and inner features? A dual-representation hypothesis is advanced, and linked speculatively to mirror neurons. (shrink)

Epistemology has recently witnessed a number of efforts to rehabilitate rationalism, to defend the existence and importance of a priori knowledge or warrant construed as the product of rational insight or apprehension (Bealer 1987; Bigelow 1992; BonJour 1992, 1998; Burge 1998; Butchvarov 1970; Katz 1998; Plantinga 1993). This effort has sometimes been coupled with an attack on naturalistic epistemology, especially in BonJour 1994 and Katz 1998. Such coupling is not surprising, because naturalistic epistemology is often associated with thoroughgoing empiricism and (...) the rejection of the a priori. In this paper, however, I shall present a conception of naturalistic epistemology that is entirely compatible with a priori justification or knowledge. The resulting conception, I claim, gives us a better appreciation of the respective merits of the rational and the empirical, as well as a better understanding of how moderate epistemological naturalism comports, at least in principle, with moderate rationalism. This paper defends moderate rationalism; but it does not defend everything rationalists have often wanted, only what it is reasonable to grant them. (shrink)

The evaluation of arguments and argumentation is best understood epistemologically. Epistemic circularity is not formally defective but it may be epistemologically objectionable. Sorenson's doubts about the syntactic approach to circularity are endorsed with qualifications. One explanation of an argument's goodness is its ability to produce justified belief in its conclusion by means of justified belief in its premises, but matters are not so simple for interpersonal argumentation. Even when an argument's premises and conclusion are justified for a speaker, this justifiedness (...) may not be transmissible to every hearer. Still, an epistemic approaeh is instructive. Arguing in enthymemes can be legitimate, e.g., because enthymemes can help produce justified persuasion in an audience that supplies the missing premises. (shrink)

There are distinct but legitimate notions of both personal justification and interpersonal justification. Interpersonal justification is definable in terms of personal justification. A connection is established between good argumentation and interpersonal justification.

In this paper, I develop what I call the Justification Encroachment (JE) Dilemma for Dormandy’s Evidentialism about Faith (EaF). The dilemma is this. If JE is true, then belief about objects of faith will be very difficult to justify, perhaps even impossible. If JE is false, then beliefs about objects of faith require no greater justification than any other belief, so that faith requires no more respect for evidence than anything else. After developing each horn, I consider very briefly how (...) a proponent of EaF might respond. (shrink)

The paper shows why and how an empirical study of fast-and-frugal heuristics can provide norms of good reasoning, and thus how (and how far) rationality can be naturalized. We explain the heuristics that humans often rely on in solving problems, for example, choosing investment strategies or apartments, placing bets in sports, or making library searches. We then show that heuristics can lead to judgments that are as accurate as or even more accurate than strategies that use more information and computation, (...) including optimization methods. A standard way to defend the use of heuristics is by reference to accuracy-effort trade-offs. We take a different route, emphasizing ecological rationality (the relationship between cognitive heuristics and environment), and argue that in uncertain environments, more information and computation are not always better (the “less-can-be-more” doctrine). The resulting naturalism about rationality is thus normative because it not only describes what heuristics people use, but also in which specific environments one should rely on a heuristic in order to make better inferences. While we desist from claiming that the scope of ecological rationality is unlimited, we think it is of wide practical use. (shrink)

Can visual thinking be a means of discovery in elementary analysis, as well as a means of illustration and a stimulus to discovery? The answer to the corresponding question for geometry and arithmetic seems to be ‘yes’ (Giaquinto [1992], [1993]), and so a positive answer might be expected for elementary analysis too. But I argue here that only in a severely restricted range of cases can visual thinking be a means of discovery in analysis. Examination of persuasive visual routes to (...) two simple theorems (Rolle, Bolzano) shows that they are not ways of discovering the theorems; the type of visual thinking involved can never be used to discover analytic theorems of a certain generality. The hypothesis that visual thinking is never a means of discovering the existence or nature of the limit of some infinite process is considered, and a likely counter-example is set out. It is still possible that restricted theorems can be discovered visually: an example from Littlewood is examined in detail and not found wanting. Even when visual thinking is not a means of discovery it can provide the idea for a proof in a direct way; an example is presented (Intermediate Value Theorem). In conclusion: it may be possible to discover theorems in elementary real analysis by visual means, but only theorems of a restricted kind; however, visual thinking in analysis can be very useful in other ways.

Several studies have found a robust effect of truth on epistemic evaluation of belief, decision, action and assertion. Thus, truth has a significant effect on normative participant evaluations. Some theorists take this truth effect to motivate factive epistemic norms of belief, action, assertion etc. In contrast, I argue that the truth effect is best understood as an epistemic instance of the familiar and ubiquitous phenomenon of outcome bias. I support this diagnosis from three interrelating perspectives: (1) by epistemological theorizing, (2) (...) by considerations from cognitive psychology and (3) by methodological reflections on the relationship between folk epistemology and epistemological theorizing.

The relevance of Fuller's version of social epistemology to argumentation theory is highlighted, in response to critics who claim that I am not sufficiently critical of the social grounds of knowledge production. Responding to Lyne, I first consider the strengths and weaknesses of relying on economic images to capture the social. Then, I tackle two contrary objections: Brian Baigrie claims social epistemology is “not social enough,” while Angelo Corlett wonders whether it may be “too social.” Finally, I counter Malcolm Ashmore, (...) who argues that social epistemology is not sensitive to reflexive implications of its own doctrines. I conclude that a rhetoric needs to be forged that enables those wishing to transform knowledge production to make their case plausibly to those whose behavior needs to be changed most. At the moment, science critics preach to the converted, a fate that the social epistemologist should not wish to share. (shrink)
