One common attitude toward abstract objects is a kind of platonism: a view on which those objects are mind-independent and causally inert. But there's an epistemological problem here: given any naturalistically respectable understanding of how our minds work, we can't be in any sort of contact with mind-independent, causally inert objects. So platonists, in order to avoid skepticism, tend to endorse epistemological theories on which knowledge is easy, in the sense that it requires no such contact—appeals to Boghossian’s notion (...) of epistemic analyticity are particularly common here, as are appeals to some broadly pragmatic account of the good standing of basic beliefs. I argue, though, that these appeals are hopeless: an argument adapted from the Benacerraf–Field challenge shows that, even if some such theory can deliver the verdict that our beliefs about abstract objects have some prima facie good standing, this good standing will inevitably be defeated.

Igal Kvart RATIONAL ASSERTIBILITY, THE STEERING ROLE OF KNOWLEDGE, AND PRAGMATIC ENCROACHMENT Abstract In the past couple of decades, there were a few major attempts to establish the thesis of pragmatic encroachment – that there is a significant pragmatic ingredient in the truth-conditions for knowledge-ascriptions. Epistemic contextualism has flaunted the notion of a conversational standard, and Stanley's subject-sensitive invariantism (SSI) promoted stakes, each of which, according to their proponents, play a major role as pragmatic (...) components in the truth conditions of knowledge ascriptions. These conceptions were propelled first and foremost by examples of knowledge ascriptions with obvious pragmatic aspects that seemed to require a pragmatic component in the truth-conditions of knowledge ascriptions in order to be accounted for. However, if such examples can be adequately explained not by pragmatic encroachment purely pragmatically, the central role that such examples play in supporting these accounts will be undermined. I lay out here a new pragmatic account, offering a different, purely pragmatic picture that explains such examples, and much more. If such an account and its associated explanations are adequate, then much of a need or a motivation for pragmatic encroachment is undermined. Specifically, I will develop the notion of rational assertibility, appealing to rational norms (which are not Gricean) as interfacing with semantic and epistemic (and other) norms to yield assertibility simpliciter. More importantly, I will argue for a well-entrenched pragmatic profile of knowledge, the so-called steering role of knowledge. Knowledge ascriptions, or simple assertions (that don't invoke the notion of knowledge), it will be argued, play a pragmatic role of steering audiences in joint deliberational setups to the speaker's preferred action by invoking an impending practical inference leading to that preferred action, and of ignoring incompatible alternatives. The recognition of rational forces as affecting, sometimes strongly and predominantly, intuitions associated with knowledge ascriptions, has important implications to philosophical methodology regarding what count as evidence for semantic features. One such lesson calls for securing examples with no significant rational forces at play in order to establish semantic features. Another calls attention to the ill-suitability of employing assertibility by figures in examples featuring deliberational setups for such a purpose in view of the role that such assertibility plays in reflecting rational aspects of such figures, in addition to their epistemic and semantic characteristics. Still another lesson points to a specific role that audiences play in such deliberational setups. (shrink)

Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition is (...) compatible with “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

In the past couple of decades, there were a few major attempts to establish the thesis of pragmatic infringement – that a significant pragmatic ingredient figures significantly in the truth-conditions for knowledge-ascriptions. As candidates, epistemic contextualism and Relativism flaunted conversational standards, and Stanley's SSI promoted stakes. These conceptions were propelled first and foremost by obviously pragmatic examples of knowledge ascriptions that seem to require a pragmatic component in the truth-conditions of knowledge ascriptions in (...) order to be accounted for. However, if such examples can be adequately explained purely pragmatically, the need that such examples seem to invoke in such a pragmatic component is undermined. Here I lay out a new pragmatic account – of action-directed pragmatics, offering a different account of such examples and their pragmatic flavor. If adequate, it obviates the above need for pragmatic enrichment. Specifically, I develop and I argue for a well-entrenched pragmatic feature – that of a steering role. The assertions of knowledge ascriptions and their denials as well as of simple assertions (that don't invoke knowledge) play a pragmatic role of steering audiences in joint deliberational setups toward, or away from, the speaker's preferred action (as well as in assertions of 'I am sure', of epistemic modals, taste assertions, causal assertions, and more.) Various features and consequences of this account are drawn. Specifically, I explain why in the bank example (and related ones) the husband, in denying the knowledge ascription, neither lies nor misleads. (shrink)

By using the general investigation framework offered by the cognitive science of religion (CSR), I analyse religion as a necessary condition for the evolutionary path of knowledge. The main argument is the "paradox of the birth of knowledge": in order to get to the meaning of the part, a sense context is needed; but a sense of the whole presupposes the sense (meaning) of the parts. Religion proposes solutions to escape this paradox, based on the imagination of sense (...) (meaning) contexts, respectively closures of these contexts through meta-senses. What is important is the practical effectiveness of solutions proposed by religion, taking into account the costs of faith and the costs of the absence of religious belief. The hypothesis has the following consequences: religion is a necessary condition for the initial evolution of knowledge and the emergence of religion is determined by the evolution of knowledge. The continuation of the solving of paradox is a Bayesian one, using explorations: a sense of the whole allows cognitive arrangements of the parties, which in turn open the possibility of a rearrangement of the whole. The contribution of religion to the emergence of sense (meaning) could be governed by the rule: any map of the world is more useful than no map; any meaning (of life) is better than no meaning. The human mind fills the perceptual and cognitive gaps, some (religious) filling solutions being true vault keys of the entire cognitive construction called the world. Knowledge is conditioned by the existence of an organized context, as the cosmos created by religion by means of explanatory meta-theories supports knowledge by closing the cognitive context and using meaning networks. The proposed analysis is consistent with a redefinition of rationality from the perspective of evolution: the importance and relevance of knowledge is determined by its practical outcome - survival. In the context of useful fictions, it does not matter what God actually does, but what we have done by believing in God. Existence has provided a pragmatic verification of the cognitive solutions that underlie the survival strategies promoted by religions. (shrink)

The main objective of the paper is to provide a conceptual apparatus of a general logical theory of language communication. The aim of the paper is to outline a formal-logical theory of language in which the concepts of the phenomenon of language communication and language communication in general are defined and some conditions for their adequacy are formulated. The theory explicates the key notions of contemporary syntax, semantics, and pragmatics. The theory is formalized on two levels: token-level and type-level. As (...) such, it takes into account the dual – token and type – ontological character of linguistic entities. The basic notions of the theory: language communication, meaning and interpretation are introduced on the second, type-level of formalization, and their required prior formalization of some of the notions introduced on the first, token-level; among others, the notion of an act of communication. Owing to the theory, it is possible to address the problems of adequacy of both empirical acts of communication and of language communication in general. All the conditions of adequacy of communication discussed in the presented paper, are valid for one-way communication (sender-recipient); nevertheless, they can also apply to the reverse direction of language communication (recipient-sender). Therefore, they concern the problem of two-way understanding in language communication. (shrink)

The stakes-shifting cases suggest that pragmatic factors such as stakes play an important role in determining our intuitive judgments of whether or not S knows that p. This seems to be in conflict with intellectualism, according to which pragmatic factors in general should not be taken into account, when considering whether or not S knows that p. This paper develops a theory of judgments of knowledge status that reconciles intellectualism with our intuitive judgments regarding the stakes-shifting cases. (...) I argue that pragmatic factors affect only our epistemic perspectives, i.e., the ways in which we evaluate S’s epistemic position. Therefore, pragmatic factors only have an indirect impact on our judgments of knowledge status. (shrink)

William James presents a preference-sensitive and future-directed notion of truth that has struck many as wildly revisionary. This paper argues that such a reaction usually results from failing to see how his accounts of truth and intentionality are intertwined. James' forward-looking account of intentionality (or "knowing") compares favorably the 'causal' and 'resemblance-driven' accounts that have been popular since his day, and it is only when his remarks about truth are placed in the context of his account of intentionality (...) that they come to seem as plausible as they manifestly did to James.

Peirce and Dewey were generally more concerned with the process of scientific activity than purely mathematical work. However, their accounts of knowledge production afford some insights into the epistemology of mathematical postulates, especially definition and axioms. Their rejection of rationalist metaphysics and their emphasis on continuity in inquiry provides the pretext for the pragmatic a priori – hypothetical and operational assumptions whose justification relies on their fruitfulness in the long run. This paper focuses on the application of (...) this idea to the epistemology of definitions and an account of progress in mathematics, although it has broader implications for the study of conceptual change and the function and basis of presuppositions in the sciences.

In Religious Experience, Wayne Proudfoot argued that a tout court rejection of reductionism in accounts of religious experience was not viable. According to Proudfoot, it’s possible to distinguish between an illegitimate practice of descriptive reductionism and the legitimate practice of explanatory reductionism. The failure to distinguish between these two forms of reductionism resulted in a protective strategy, or an attempt to protect religious experience from the reach of scientific explanation. Among the theorists whom he accused of deploying this illegitimate (...) strategy Proudfoot included William James and his work in The Varieties of Religious Experience. In this article, I argue that while James does occasionally deploy a protective strategy in Varieties, this is not the only nor most important method of treating religious experience James developed. Implicit in his rejection of medical materialism, James not only deploys the protective strategy Proudfoot criticizes, but the pragmatic method with which he treats all claims. I argue that James’s pragmatic method leads to what James called noetic pluralism, or the view that there is no privileged knowledge practice, but a plurality of knowledge practices, and that this method puts pressure on the explanatory reductionist, who is implicitly committed to noetic monism.

The notion of relevance plays a role in many accounts of knowledge and knowledge ascription. Although use of the notion is well-motivated, theorists struggle to codify relevance. A reasonable person standard of relevance addresses this codification problem, and provides an objective and flexible standard of relevance; however, treating relevance as reasonableness seems to allow practical factors to determine whether one has knowledge or not—so-called “pragmatic encroachment.” I argue that a fuller understanding of reasonableness and of (...) the role of practical factors in the acquisition of knowledge lets us avoid pragmatic encroachment. (shrink)

How should we account for the contextual variability of knowledge claims? Many philosophers favour an invariantist account on which such contextual variability is due entirely to pragmatic factors, leaving no interesting context-sensitivity in the semantic meaning of ‘know that.’ I reject this invariantist division of labor by arguing that pragmatic invariantists have no principled account of embedded occurrences of ‘S knows/doesn’t know that p’: Occurrences embedded within larger linguistic constructions such as conditional sentences, attitude verbs, expressions of (...) probability, comparatives, and many others, I argue, give rise to a threefold problem of embedded implicatures.

The aim of this paper is to bring to light the anthropological dimension of Kant’s account of cognition as it is developed in the Lectures on Anthropology. I will argue that Kant’s anthropology of cognition develops along two complementary lines. On the one hand, it studies Nature’s intentions for the human species – the “natural” dimension of human cognition. On the other hand, it uses this knowledge to help us realise of our cognitive purposes – the “pragmatic” dimension (...) of human cognition. Insofar as it is intended for us as embodied human agents whose cognition takes place in the empirical world, it is concerned with the knowledge of the natural subjective conditions that help or hinder our cognition. Yet the idea that Kant’s anthropology of cognition has a pragmatic dimension turns out to be problematic. For whilst pragmatic anthropology is defined as ‘the investigation of what he as a free-acting being makes of himself, or can and should make of himself’ (A 7:119), by contrast with acting, cognising seems to be beyond the realm of voluntary action. However, I will show that Kant’s account of cognition makes room for a form of epistemic control that is sufficient to account for the possibility of its pragmatic dimension. Therefore, far from portraying human beings as disembodied pure minds, Kant’s account not only acknowledges the empirical, contingent and messy features of our cognition, it helps us become better, more efficient knowers by recommending how we can improve upon the subjective features that further or hinder our cognitive perfection. I will conclude by drawing the implications on my interpretation for our overall understanding of Kant’s account of cognition. (shrink)

In recent work on the semantics of ‘knowledge’-attributions, a variety of accounts have been proposed that aim to explain the data about speaker intuitions in familiar cases such as DeRose’s Bank Case or Cohen’s Airport Case by means of pragmatic mechanisms, notably Gricean implicatures. This paper argues that pragmatic explanations of the data regarding ‘knowledge’-attributions are unsuccessful and concludes that in explaining those data we have to resort to accounts that (a) take those data (...) at their semantic face value (Epistemic Contextualism, Subject-Sensitive Invariantism or Epistemic Relativism), or (b) reject them on psychological grounds (Moderate Insensitive Invariantism). To establish this conclusion, the paper relies solely upon widely accepted assumptions about pragmatic theory, broadly construed, and on the Stalnakerian insight that linguistic communication takes place against the backdrop of a set of mutually accepted propositions: a conversation’s common ground.

Any good theory of knowledge ascriptions should explain and predict our judgments about their felicity. I argue that any such explanation must take into account a distinction between three ways of using knowledge ascriptions: to suggest acceptance of the embedded proposition, to explain or predict a subject's behavior or attitudes, or to understand the relation of knowledge as such. The contextual effects on our judgments about felicity systematically differ between these three types of uses. Using such a (...) distinction is, in principle, open to both contextualist and pragmatic invariantist accounts of knowledge ascriptions. However, there are some implications pertaining to the use of the “method of cases” in the debate about knowledge ascriptions. (shrink)

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent (...) to believe a proposition is for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny. (shrink)

In “The Myth of Factive Verbs” (Hazlett 2010), I had four closely related goals. The first (pp. 497-99, p. 522) was to criticize appeals to ordinary language in epistemology. The second (p. 499) was to criticize the argument that truth is a necessary condition on knowledge because “knows” is factive. The third (pp. 507-19) – which was the intended means of achieving the first two – was to defend a semantics for “knows” on which <S knows p> can be (...) true even if p isn’t true. The fourth (Ibid.) – which seemed necessary for the success of the third – was to defend a pragmatic account of the fact that utterances of <S knows p> typically imply p, on which the implication in those cases is down to conversational implicature. In this paper I’ll go after these goals again, with an emphasis on the second. Our topic will be whether the factivity of “knows” (whatever this amounts to) supports the truth condition on knowledge. A new goal will be to defend my argument against some criticisms from John Turri (2011) and Savas Tsohatzidis (forthcoming). We’ll first look at the truth condition (§1) and factive presupposition (§§2 – 3), before turning to replies to Turri and Tsohatzidis (§§4 – 7). (shrink)

The aim of this paper is make a contribution to the ongoing search for an adequate concept of the a priori element in scientific knowledge. The point of departure is C.I. Lewis’s account of a pragmatic a priori put forward in his "Mind and the World Order" (1929). Recently, Hasok Chang in "Contingent Transcendental Arguments for Metaphysical Principles" (2008) reconsidered Lewis’s pragmatic a priori and proposed to conceive it as the basic ingredient of the dynamics of an (...) embodied scientific reason. The present paper intends to further elaborate Chang’s account by relating it with some conceptual tools from cognitive semantics and certain ideas that first emerged in the context of the category-theoretical foundations of mathematics.

Infallibilism leads to skepticism, and fallibilism is plagued by the threshold problem. Within this narrative, the pragmatic turn in epistemology has been marketed as a way for fallibilists to address the threshold problem. In contrast, pragmatic versions of infallibilism have been left unexplored. However, I propose that going pragmatic offers the infallibilist a way to address its main problem, the skeptical problem. Pragmatic infallibilism, however, is committed to a shifty view of epistemic certainty, where the strength (...) of a subject’s epistemic state can vary depending upon the practical context. Pragmatic views of epistemic strength are quite radical so the argumentative goal of my discussion is to argue for its plausibility, thereby arguing for the plausibility of pragmatic infallibilism. To do so, I discuss the role that the framing of decision problems and the construction of our deliberative attitudes have in our theories of rational choice. And I explore a way in which these necessary components of a normative theory of rationality can be used to motivate pragmatic views of evidential support. Finally, since the plausibility of our pragmatic account will depend upon the plausibility of a constructive account of rational choice, I conclude by comparing the adequacy of the constructive account with orthodox Bayesian and knowledge-based accounts.

I first present a brief interpretation of Sosa’s virtue epistemology by showing how it is arguably better than Goldman’s process reliabilism, why Sosa distinguishes between animal knowledge and reflective knowledge, and how Sosa’s recent account of knowing full well can deal with pragmatic encroachment. Then, I raise two worries about Sosa’s account: (a) Sosa’s claim that one might have animal knowledge without knowing reflectively or knowing full well implies that one’s true belief might manifest both competence (...) and luck, which seems to pose a challenge to Sosa’s solution to the Gettier problem; (b) intellectual virtue or competence does not seem to be a necessary condition for knowledge: there are cases where one knows without possessing the relevant intellectual virtue or competence. Finally, I suggest a responsibilist account of knowledge and show how it can not only handle the cases that pose a problem for Sosa’s account but also explain our intuitions about different grades of knowledge. (shrink)

In this paper I consider the prospects for a skeptical version of infallibilism. For the reasons given above, I think skeptical invariantism has a lot going for it. However, a satisfactory theory of knowledge must account for all of our desiderata, including that our ordinary knowledge attributions are appropriate. This last part will not be easy for the infallibilist invariantist. Indeed, I will argue that it is much more difficult than those sympathetic to skepticism have acknowledged, as there (...) are serious problems with regarding paradigmatic, typical knowledge attributions as loose talk, exaggerations, or otherwise practical uses of language. So, I do not think the pragmatic story that skeptical invariantism needs is one that works without a supplemental error theory of the sort left aside by purely pragmatic accounts of knowledge attributions. In its place, I will offer a compromise pragmatic and error view that I think delivers everything that skeptics can reasonably hope to get. (shrink)

Moderate Pragmatic Invariantism (MPI) has been criticized in the literature for postulating implicatures that are not straightforwardly cancellable. Defenders of MPI have responded that the data are not as clear-cut as one might wish. This paper grants the defenders of MPI, for the sake of argument, that the implicatures in question are cancellable and then turns this admission against them. In particular, the paper offers Bank Case variants in which the conversational implicatures postulated by MPI are contextually suspended – (...) and thus cancelled. Since our intuitions do not vary between the original Bank Case and these novel types of cases, the explanation offered by MPI must be mistaken. Our varying truth-value intuitions in the Bank Cases cannot be accounted for by means of conversational implicatures. (shrink)

What is scientific progress? On Alexander Bird’s epistemic account of scientific progress, an episode in science is progressive precisely when there is more scientific knowledge at the end of the episode than at the beginning. Using Bird’s epistemic account as a foil, this paper develops an alternative understanding-based account on which an episode in science is progressive precisely when scientists grasp how to correctly explain or predict more aspects of the world at the end of the episode than at (...) the beginning. This account is shown to be superior to the epistemic account by examining cases in which knowledge and understanding come apart. In these cases, it is argued that scientific progress matches increases in scientific understanding rather than accumulations of knowledge. In addition, considerations having to do with minimalist idealizations, pragmatic virtues, and epistemic value all favor this understanding-based account over its epistemic counterpart. (shrink)

Take pragmatic encroachment to be the view that whether one knows that p is determined at least in part by the practical consequences surrounding the truth of p. This view represents a significant departure from the purist orthodoxy, which holds that only truth-relevant factors determine whether one knows. In this chapter I consider some consequences of accepting pragmatic encroachment when applied to problems of political knowledge and political ignorance: first, that there will be cases in which it (...) will not be practically rational to acquire political knowledge when the stakes surrounding one’s political actions are high; second, that political knowledge can be more easily acquired when one values the welfare of others less; and third, that pragmatic encroachment may fail to account for a form of epistemic injustice when it comes to evaluating the political knowledge of members of marginalized groups. I argue that while these consequences are undesirable, the extent to which the pragmatic encroacher is committed to them depends both on the details of the theory, as well as the extent to which one considers political knowledge to be important. (shrink)

I present a challenge to epistemological pragmatic encroachment theories from epistemic injustice. The challenge invokes the idea that a knowing subject may be wronged by being regarded as lacking knowledge due to social identity prejudices. However, in an important class of such cases, pragmatic encroachers appear to be committed to the view that the subject does not know. Hence, pragmatic encroachment theories appear to be incapable of accounting for an important type of injustice – namely, discriminatory (...) epistemic injustice. Consequently, pragmatic encroachment theories run the risk of obscuring or even sanctioning epistemically unjust judgments that arise due to problematic social stereotypes or unjust folk epistemological biases. In contrast, the epistemological view that rejects pragmatic encroachment – namely, strict purist invariantism – is capable of straightforwardly diagnosing the cases of discriminatory epistemic injustice as such. While the challenge is not a conclusive one, it calls for a response. Moreover, it illuminates very different conceptions of epistemology’s role in mitigating epistemic injustice. (shrink)

This paper is a companion piece to my earlier paper “Fallibilism and Concessive Knowledge Attributions”. There are two intuitive charges against fallibilism. One is that it countenances the truth (and presumably acceptability) of utterances of sentences such as “I know that Bush is a Republican, though it might be that he is not a Republican”. The second is that it countenances the truth (and presumably acceptability) of utterances of sentences such as “I know that Bush is a Republican, even (...) though I’m not certain that he is”, or “I know that Bush it a Republican, even though it isn’t certain that he is.” In “Fallibilism and Concessive Knowledge Attributions”, I argue that fallibilism in epistemology does not countenance the truth of utterances of sentences such as “I know that Bush is a Republican, though it might be that he is not a Republican”. In this paper, I argue that there are independent reasons for thinking that utterances of sentences such as “I know that Bush is a Republican, though I’m not certain that he is” and “I know that Bush is a Republican, though it’s not certain that he is” are unassertible. More specifically, I argue that these are simply instances of Moore’s Paradox, such as “Dogs bark, but I don’t know that they do.” The right account of Moore’s Paradox does not involve the falsehood of the semantic content of the relevant utterances, but rather their pragmatic unacceptability. So the anti-fallibilist intuitions turn out to have pragmatic, rather than semantic import, and therefore do not tell against the truth of fallibilism. Fallibilism in epistemology is often thought to be theoretically desirable, but intuitively problematic. My purpose with these two papers is to show that fallibilism is not intuitively problematic.

Since the transparency approach to introspection need not posit a dedicated mechanism specialized for detecting one’s own mental states, its economy is often viewed as a major advantage by both proponents and opponents. But sometimes economy comes at the cost of relying on controversial views of the natures of mental states. Perceptual experience is a case in point. For example, Alex Byrne’s account relies on the view that experience constitutively involves belief, and Matthew Boyle’s account relies on the view that (...) experience constitutively involves a form of implicit consciousness of experience. In this paper, I develop a transparency account of our access to our experiences that retains the benefit of economy while avoiding the cost of relying on controversial views of the nature of experience. I start by discussing Byrne’s and Boyle’s accounts. I focus on the problems that lead them to hold the controversial views they do, and raise some challenges to their solutions. I then develop my own account. I argue that when you attend to an object, your experience gives you justification to believe that you see the object (under some descriptions). I close by highlighting some advantages of my account. I argue that it (1) can solve the problems facing Byrne and Boyle without relying on controversial views of the nature of experience; (2) respects the idea that there is something special about our access to our minds; and (3) can be generalized to other cases of introspection.

Keith DeRose has argued that the two main problems facing subject-sensitive invariantism come from the appropriateness of certain third-person denials of knowledge and the inappropriateness of now you know it, now you don't claims. I argue that proponents of SSI can adequately address both problems. First, I argue that the debate between contextualism and SSI has failed to account for an important pragmatic feature of third-person denials of knowledge. Appealing to these pragmatic features, I show that (...) straightforward third-person denials are inappropriate in the relevant cases. And while there are certain denials that are appropriate, they pose no problems for SSI. Next, I offer an explanation, compatible with SSI, of the oddity of now you know it, now you don't claims. To conclude, I discuss the intuitiveness of purism, whose rejection is the source of many problems for SSI. I propose to explain away the intuitiveness of purism as a side-effect of the narrow focus of previous epistemological inquiries. (shrink)

The paper aims to investigate some aspects of Ernst Mach’s epistemology in the light of the problem of human orientation in relation to the world (Weltorientierung), which is a main topic of Western philosophy since Kant. As will be argued, Mach has been concerned with that problem, insofar as he developed an original pragmatist epistemology. In order to support my argument, I firstly investigate whether Mach defended a nominalist or a realist account of knowledge and compare his view to (...) those elaborated by other pragmatist thinkers, such as W. James, H. Vaihinger and H. Poincaré. Secondly, the question of what does it mean, for Mach, to orient ourselves in science is addressed. Finally, it will be argued that, although Mach tried to keep his epistemology restricted to a mere operational and economical account of science, that question involves the wider plane of practical philosophy.

Epistemologists have become increasingly interested in the practical role of knowledge. One prominent principle, which I call PREMISE, states that if you know that p, then you are justified in using p as a premise in your reasoning. In response, a number of critics have proposed a variety of counter-examples. In order to evaluate these problem cases, we need to consider the broader context in which this principle is situated by specifying in greater detail the types of activity that (...) the principle governs. I argue that if PREMISE is interpreted as governing deductive reasoning, then the examples lose their force. In addition, I consider the cases, discussed by Keith DeRose, where the subject is in more than one practical context at the same time. In order to account for these latter cases, we need to further specify the scope of PREMISE. I distinguish two ways of understanding PREMISE, as a knowledge-action principle and as a knowledge-deliberation principle. I conclude by arguing for the knowledge-deliberation version of the principle and by exploring what this principle says about the practical role of knowledge. (shrink)

Why did such highly abstract ideas as truth, knowledge, or justice become so important to us? What was the point of coming to think in these terms? This book presents a philosophical method designed to answer such questions: the method of pragmatic genealogy. Pragmatic genealogies are partly fictional, partly historical narratives exploring what might have driven us to develop certain ideas in order to discover what these do for us. The book uncovers an under-appreciated tradition of (...) class='Hi'>pragmatic genealogy which cuts across the analytic-continental divide, running from the state-of-nature stories of David Hume and the early genealogies of Friedrich Nietzsche to recent work in analytic philosophy by Edward Craig, Bernard Williams, and Miranda Fricker. However, these genealogies combine fictionalizing and historicizing in ways that even philosophers sympathetic to the use of state-of-nature fictions or real history have found puzzling. To make sense of why both fictionalizing and historicizing are called for, the book offers a systematic account of pragmatic genealogies as dynamic models serving to reverse-engineer the points of ideas in relation not only to near-universal human needs, but also to socio-historically situated needs. This allows the method to offer us explanation without reduction and to help us understand what led our ideas to shed the traces of their practical origins. Far from being normatively inert, moreover, pragmatic genealogy can affect the space of reasons, guiding attempts to improve our conceptual repertoire by helping us determine whether and when our ideas are worth having.

On Fred Dretske’s account of knowledge, the Epistemic Closure Principle for knowledge is not valid. Dretske takes this to be a virtue since the account is thus able to saves ordinary knowledge from skepticism. On it, you may know that you have hands, although you do not know that you are not a handless brain in a vat. As a correlate, the account also has to countenance the existence of what has come to be known as ‘abominable (...) conjunctions’ – conjunctions of the form ‘I know I have hands but I do not know that I am not a handless brain in a vat’. These conjunctions are abominable in that they look false or in some way incoherent. Dretske suggests that the abomination is merely pragmatic and can be explain in terms of conversational features, more precisely, in terms of the Gricean Conversation Principles and its associated Maxims of Conversation. I argue that no such Gricean explanation is forthcoming, and that the abomination cannot be thought of as a merely pragmatic or conversational phenomenon. As I show, the abomination goes deeper, into the semantics. (shrink)

In this paper I defend the view that knowledge is belief for reasons that are both objectively and subjectively sufficient from an important objection due to Daniel Whiting, in this journal. Whiting argues that this view fails to deal adequately with a familiar sort of counterexample to analyses of knowledge, fake barn cases. I accept Whiting’s conclusion that my earlier paper offered an inadequate treatment of fake barn cases, but defend a new account of basic perceptual reasons that (...) is consistent with the account of knowledge and successfully deals with fake barns.

The paper explicates a new way to model the context-sensitivity of 'knows', namely a way that suggests a close connection between the content of 'knows' in a context C and what is pragmatically presupposed in C. After explicating my new approach in the first half of the paper and arguing that it is explanatorily superior to standard accounts of epistemic contextualism, the paper points, in its second half, to some interesting new features of the emerging account, such as its (...) compatibility with the intuitions of Moorean dogmatists. Finally, the paper shows that the account defended is not subject to the most prominent and familiar philosophical objections to epistemic contextualism discussed in the recent literature. (shrink)

It is widely thought that knowledge is factive – only truths can be known. However, this view has been recently challenged. One challenge appeals to approximate truths. Wesley Buckwalter and John Turri argue that false-but-approximately-true propositions can be known. They provide experimental findings to show that their view enjoys intuitive support. In addition, they argue that we should reject the factive account of knowledge to avoid widespread skepticism. A second challenge, advanced by Nenad Popovic, appeals to multidimensional geometry (...) to build a case where it seems intuitive that a person knows p even though p is false. In addition, Popovic argues that we should reject the factive account of knowledge because most of us would not become widespread skeptics if we discovered that ordinary objects in our world are actually four-dimensional. In this paper, we defend the factive account of knowledge against these arguments by challenging the intuitive appeal of the cases and arguing that there is no real threat of widespread skepticism for the factive account of knowledge.

Arthur Danto’s recent book, Andy Warhol, leads the reader through the story of the iconic American’s artistic life highlighted by a philosophical commentary, a commentary that merges Danto’s aesthetic theory with the artist himself. Inspired by Warhol’s Brillo Box installation, art that in Danto’s eyes was indiscernible from the everyday boxes it represented, Danto developed a theory that is able to differentiate art from non-art by employing the body of conceptual art theory manifest in what he termed the ‘artworld’. The (...) strength of Danto’s theory is found in its ability to explain the art of the post-modern era. His body of work weaves philosophy, art history and art criticism together, merging his aesthetic philosophy with his extensive knowledge of the world of art. Danto’s essentialist theory of embodied meaning provides him with a critical tool that succeeds in explaining the currents of contemporary art, a task that many great thinkers of art history were unable to do. If Warhol inspired Danto to create a philosophy of art, it is appropriate that Danto write a tribute to Warhol that traces how Warhol brought philosophy into art. Danto’s account of ‘Warhol as philosopher’ positions him as a pivotal figure in the history of twentieth-century art, effecting a sea change in how art was made and viewed. Warhol achieved this by conceiving of works that embodied the answers to a series of philosophical puzzles surrounding the nature of art. Warhol, as Danto describes him, manifests himself in his art because he had transformed himself, in a way, into an icon of the times. This pragmatist notion that art should undermine the dichotomies that exist between art and life would, by some accounts, position Warhol to be the philosopher that Danto claims him to be, for he dissolved the philosophical questions posted by late modern aesthetic thinkers by creating art that imploded the accepted notions of art at the time. One of Danto’s greatest contributions to aesthetics is his theory’s ability to distinguish art from non-art, recognizing that it is the artist’s intention that levels the sublimity of art into the commonplace, thereby transfiguring the everyday. However, acknowledging this achievement, I argue that Warhol’s philosophical contribution actually manifests itself in a manner different from that proposed by Danto. Danto maintains that the internal drive of art leads to the unfolding of art theoretical concepts that ineluctably shift the terrain of world of art. I would agree with Danto that Warhol, almost as Hegel viewed Napoleon as Geist on a horse, pushed forward the boundaries of art through the actualization of art’s internal drive. But I would disagree that the conceptual nature of art is one that unfolds merely as a relation of concepts that artists trace through a connection to the meaning of history they forge using their unmediated grasp of style. Rather, I would argue that the artist’s style is not bound so narrowly to the meanings they express. Through their aesthetic articulations, artists initiate a process of social interaction. This process employs the philosophical logic which Danto attributes to Warhol indirectly, and through it, it is able to transfigure the vocabulary of art—the concepts of the artworld—by superseding the language of modernism. Warhol’s philosophical contribution is seen in his mastery of both the medium of art and the underlying logic of the medium’s expression and reception. (shrink)

“Probably Peirce’s best-known works are the first two articles in a series of six that originally were collectively entitled Illustrations of the Logic of Science and published in Popular Science Monthly from November 1877 through August 1878. The first is entitled ‘The Fixation of Belief’ and the second is entitled ‘How to Make Our Ideas Clear.’ In the first of these papers Peirce defended, in a manner consistent with not accepting naive realism, the superiority of the scientific method over other (...) methods of overcoming doubt and ‘fixing belief.’” — Robert Burch, “Charles Sanders Peirce,” entry in the Stanford Encyclopedia of Philosophy (2021 revision) -/- “Pragmatist epistemologies often explore how we can carry out inquiries in a self-controlled and fruitful way. (Where much analytic epistemology centres around the concept of knowledge, considered as an idealised end-point of human thought, pragmatist epistemology centres around the concept of inquiry, considered as the process of knowledge-seeking and how we can improve it.) So pragmatists often provide rich accounts of the capacities or virtues that we must possess in order to inquire well, and the rules or guiding principles that we should adopt. A canonical account is Peirce’s classic early paper ‘The Fixation of Belief‘. Here Peirce states that inquiry is a struggle to replace doubt with “settled belief“, and that the only method of inquiry that can make sense of the fact that at least some of us are disturbed by inconsistent beliefs, and will subsequently reflect upon which methods of fixing belief are correct is the Method of Science, which draws on the Pragmatic Maxim described above. This contrasts with three other methods of fixing belief: i) refusing to consider evidence contrary to one’s favored beliefs (the Method of Tenacity), ii) accepting an institution’s dictates (the Method of Authority), iii) developing the most rationally coherent or elegant-seeming belief-set (the A Priori Method).“ — Catherine Legg, “Pragmatism,” entry in the Stanford Encyclopedia of Philosophy (2021 revision).

Abstract. In Dynamics of Reason Michael Friedman proposes a kind of synthesis between the neokantianism of Ernst Cassirer, the logical empiricism of Rudolf Carnap, and the historicism of Thomas Kuhn. Cassirer and Carnap are to take care of the Kantian legacy of modern philosophy of science, encapsulated in the concept of a relativized a priori and the globally rational or continuous evolution of scientific knowledge,while Kuhn´s role is to ensure that the historicist character of scientific knowledge is taken (...) seriously. More precisely, Carnapian linguistic frameworks, guarantee that the evolution of science procedes in a rational manner locally,while Cassirer’s concept of an internally defined conceptual convergence of empirical theories provides the means to maintain the global continuity of scientific reason. In this paper it is argued that Friedman’s neokantian account of scientific reason based on the concept of the relativized a priori underestimates the pragmatic aspects of the dynamics of scientific reason. To overcome this short-coming, I propose to reconsider C.I. Lewis’s account of a pragmatic the priori, recently modernized and elaborated by Hasok Chang.

In “Stakes, Withholding, and Pragmatic Encroachment on Knowledge,” I used a variety of cases, including cases of forced choice, to illustrate my explanation of how and why some pragmatic factors, but not others, can affect whether an agent knows. In his recent contribution, Andy Mueller argues that cases of forced choice actually pose a dilemma for my account. In this paper I reply.

Popper's account of refutation is the linchpin of his famous view that the method of science is the method of conjecture and refutation. This thesis critically examines his account of refutation, and in particular the practice he deprecates as avoiding a refutation. I try to explain how he comes to hold the views that he does about these matters; how he seeks to make them plausible; how he has influenced others to accept his mistakes, and how some of the ideas (...) or responses to Popper of such people are thus similarly mistaken. I draw some distinctions necessary to the provision of an adequate account of the so-called practice of avoiding a refutation, and try to rid the debate about this practice of at least one red herring. I analyse one case of 'avoiding' a refutation in detail to show how the rationality of scientific practice eludes both Popper and many of his commentators. Popper's skepticism about contingent knowledge prevents him from providing an acceptable account of contingent refutation, and so his method is really the method of conjecture and conjecture. He cannot do without the concepts of knowledge and refutation, however, if his account of science is to be plausible or persuasive, and so he equivocates between, amongst other things, refutation as disproof and refutation as the weaker notion of discorroboration. I criticise David Stove's account of this matter, in particular to show how he misses this point. An additional advantage Popper would secure from this equivocation is that if refutations were mere discorroborations they would be easier to achieve, and hence more common in science, than is the case. On Popper's weak notion of refutation, it would be possible to refute true theories since corroboration does not entail truth. There are two other related doctrines Popper holds about refutation which, if accepted, make some refutations seem easier to obtain than is the case. I call these doctrines 'Strong Popperian Falsificationism' (SPF) and 'Weak Popperian Falsificationism' (WPF). SPF is the false doctrine that if a prediction from some theory is refuted then that theory is refuted. Popper does not always endorse SPF. In particular, when confronted with a counterexample to it, he retreats to WPF, which is the false doctrine that if a prediction from some theory is refuted then that theory is prima facie refuted. WPF , or even SPF, can seem plausible if one has in mind predictions derived from theories in strong or conclusive tests of those theories, which I suggest Popper characteristically does. v Popper is disposed to describe any such case of predictive failure which does not lead to the refutation of the theory concerned as one in which that refutation has been avoided. To reinforce his portrayal of the refutation, or the attempted refutation, of major scientific theories as the rational core of scientific practice, Popper treats the so-called practice of avoiding a refutation as untypical of science, and much so-called avoidance he dismisses as unscientific or pseudo-scientific. I argue that his notion of avoiding a refutation is incoherent. Popper is further driven to believe that such avoidance is possible, however, because he conflates sentences with propositions and propositions with propositional beliefs. Also, he wishes to avoid being saddled with the relativisim that is a consequence of his weak account of refutation as discorroboration. Popper believes that ad hoc hypotheses are the most important of the unscientific means of avoiding a refutation. I argue that his account of such hypotheses is also incoherent, and that several hypotheses thought to be ad hoc in his sense are not. Such hypotheses appear to be so largely because of Popper's use of rhetoric and partly because these hypotheses are unacceptable for other reasons. I conclude that to know that a hypothesis is ad hoc in Popper's sense does not illuminate scientific practice. Popper has also attempted to explicate ad hocness in terms of some undesirable, or allegedly undesirable, properties of hypotheses or the explanations they would provide. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which is not. In the former case I argue that non-circularity is clearly preferable to non-ad hocness as a criterion for a satisfactory explanation or explanans, as the case may be, and in the latter case that Popper is barking up the wrong tree. Some cases of so-called avoidance are obviously not unscientific. The discovery of Neptune from a prediction based on the reasonable belief that there were residual perturbations in the motion of Uranus is an important case in point, and one that is much discussed in the literature. The manifest failure of astronomers to account for Uranus's motion did not lead to the refutation of Newton's law of gravitiation, yet significant scientific progress obviously did result. Retreating to WPF, Popper claims that Newton's law was prima facie refuted. In general, astronomers have never shared this view, and they are correct in not doing so. I argue that the law of gravitation would have been prima facie refuted only if there had been good reason at the time to believe as false what is true, namely, that an unknown trans-Uranian planet was the cause of those Uranian residuals. Knowledge of the trans-Uranian region was then so slight that it was merely a convenient assumption, one which there was little reason to believe was false, that the known influences on Uranus's motion were the only such influences. I conclude that in believing vi or supposing that it was this assumption that was false, rather than the law of gravitation, Leverrier and Adams, the co-predictors of Neptune, were acting rationally and intelligently. Popper's commentators offer a variety of accounts of the alleged practice of avoiding a refutation, and of this case in particular. I analyse a sample of their accounts to show how common is the acceptance of some of Popper's basic mistakes, even amongst those who claim to reject his falsificationism, and to display the effects on their accounts of this acceptance of his mistakes. Many commentators recognize that anomalies are typically dealt with by changes in the boundary conditions or in other of the auxiliary propositions employed. Where many still go wrong, however, is in retaining the presupposition of WPF which encouraged Popper to hold the contradictory view about anomalies in the first place. Thus Imre Lakatos and others, for example, have developed a 'siege mentality' about major scientific theories; they see them as under continual threat of refutation from anomalies, and so come to believe that dogmatism is essential in science if such theories are to survive as they do. I examine various such doomed attempts to reconcile Popper with the history of science. It is a common failure in this literature to conflate or to fail to see the need to distinguish a belief from a supposition, and an epistemic reason from a pragmatic reason. I argue that only if one does draw these distinctions can one give an adequate account of how anomalies are rationally dealt with in science. The other important strand in Popper's thinking about 'avoidance' of refutation which has seriously misled some of his commentators is his unfounded belief in the dangers of ad hoc hypotheses. I examine the accounts that a sample of such commentators provide of the trans-Uranian planet hypotheses of Leverrier and Adams. These commentators imply or assert what Popper only hints at, namely, that there is something fishy about this hypothesis. I provide a further defence of the rationality of entertaining this hypothesis at the time. I conclude with a few remarks about Popper's dilemma in respect of scientific practice and his long standing emphasis on refutations. (shrink)

ABSTRACT: It is a familiar story that Kant’s defence of our synthetic a priori cognition in the Critique of Pure Reason suffered sharp criticism throughout the extended philosophical revolutions that established analytic philosophy, the pragmatist tradition, and the phenomenological tradition as dominant philosophical movements in the first half of the twentieth century. One of the most important positive adaptations of Kant’s outlook, however, was the combined analytic and pragmatist conceptions of the a priori that were developed by the American philosophers (...) C. I. Lewis (1883–1964) and Wilfrid Sellars (1912–1989), most notably in Lewis’s 1929 classic, Mind and the World Order, followed by Sellars’ critical reworking of Lewis’s outlook in ‘Is There a Synthetic A Priori?’ (1953) and other mid-century articles. Both Lewis and Sellars defended central aspects of Kant’s analysis of our a priori knowledge of mind-independent physical objects and necessary causal connections. But both also radically transformed Kant’s view by defending the idea that there are alternative a priori conceptual frameworks that are subject to an ongoing process of reassessment and replacement on overall pragmatic and explanatory grounds. Furthermore, while Sellars’ answer to his question, ‘Is There a Synthetic A Priori?’ thus represented a partial endorsement of Lewis’s pragmatic relativization of the a priori, I argue that Sellars’ account of meaning diverged from Lewis in ways that constituted a significant improvement upon the previous ‘analytic’ defenses of the a priori, not only in Lewis but in general. This arguably has implications for wider disputes concerning the nature and possibility of a priori knowledge in non-formal domains. (shrink)

Some emotional representations seem to be unreliable. For instance, we are often afraid when there is no danger present. If emotions such as fear are so unreliable, what function do they have in our representational system? This is a problem for representationalist theories of emotion. I will argue that seemingly unreliable emotional representations are reliable after all. While many mental states strike an optimal balance between minimizing inaccurate representations and maximizing accurate representations, some emotional representations only aim at maximizing accuracy. (...) They detect important phenomena such as danger based on little evidence, which will lead to a lot of false alarms. When it matters, however, these emotional representations will detect danger and other important phenomena. Often, one is better scared (and wrong) than sorry. (shrink)

The discrepancy between individual women and the stereotypes attributed to the group as a ‎whole has become progressively greater and more explicit over the course of history. The stereotypes remain the same age-old ‎allegations whilst the ‎developments in the occupations of women and the traits they have opportunity to express have increased the distance between women and those ascribed traits. Stereotypes’ abstention from revision in light of contrary evidence constitutes an epistemic paradox for it entails conflict between the stereotypical (...) class='Hi'>knowledge and empirical evidence, as well as between the stereotypical knowledge and other empirical knowledges. This paradox of stubbornness also raises the question as to the epistemic source of stereotypes. For, people at young ages encounter evidence which should have formed a more complex knowledge regarding women rather than the pervasive stereotypical knowledge. It is this extremity of absurdness of stereotypes regarding women that is utile to understanding stereotypes as a whole. The epistemic paradox that is engrained in all stereotypes is exposed uncompromisingly by this group. The paradox cannot be dismissed with excuses of having a small basis of evidence, such as may be said regarding other social groups with which one may have had minimal or no contact. Thus, stereotypes of women provide a limit case to understanding the epistemology of this paradoxical form of knowledge. The traits and epistemic phenomena which render stereotypes epistemically puzzling and intriguing is the relationship between knowledges. Stereotypical knowledge regarding women as a group conflict with one’s experience-founded knowledges of particular women, deeming the corporate body of knowledge incoherent. Quine’s theory of knowledge, with its holistic empirical approach endorsing conceptual schemes, provides fertile ground for this analysis. The novelty in his account is his establishment of the criteria of coherency, which shifts the focal point of epistemic inquiry away from the adequacy of individual knowledges with empirical evidence to the intra-knowledge relationships themselves. In his empiricism, Quine rather examines the interactions between knowledges and the overarching coherence of the body of knowledge as a holistic unit. Quine creates place in his account for mechanism which provide for the epistemic incongruences of stubbornness and conflict found between stereotypical knowledges and empirical evidence. These very mechanisms are what this paper requests to examine. Quine, ultimately, formulates knowledge as a collectively held fabric consisting of relations and of posits – socially constructed mechanisms which are empirically-irreducible and implemented pragmatically for the organisation of empirical evidence. According to Quine, the fabric formation is a conceptual scheme sourced in social heritage. People are bestowed with an eclectic framework of ‎knowledge to pragmatically merge between an inherited, collective conceptual scheme and the personally experienced empirical evidence. This paper will delve into Quine’s fabric of knowledge, its relations, and inner-mechanisms. The finding of stereotypes to be an age-old posit entrenched pragmatically – thus stubbornly – in the collective conceptual scheme, will explain the epistemic paradoxes they entail and offer insight to their revision in light of empiric reality and its women.

In this dissertation, I aim to develop and defend a novel, pragmatist approach to foundational questions about meaning, especially the meaning of deontic moral vocabulary. Drawing from expressivists and inferentialists, I argue that meaning is best explained by the various kinds of norms that govern the use of a vocabulary. Along with inferential norms, I argue we must extend our account to discursive norms that govern normative statuses required to felicitously utter certain speech-acts—norms of authority—and the transitions in normative statuses (...) affected by speech-acts—pragmatic norms. These structural discursive norms differentiate discursive practices and account for distinctive features such as objectivity and motivational import that some have and others lack. The structure exhibited by a practice is then explained in terms of its utility, making it possible to see how different discursive practices are answerable to the different needs and purposes of the discursive beings who use them. I call the resulting explanatory framework a pragmatic analysis of linguistic meaning (PALM). -/- Turning my attention to moral “ought,” I argue that the structural discursive norms of moral discourse differentiate it from other objective discourses, like empirical discourse, on the one hand, and from other normative discourses, like prudential discourse, on the other. Drawing on work in evolutionary psychology and anthropology, I complete the PALM with an account of moral discourse a meta-normative practice with a metacoordinative function. Its utility for the discursive beings who use it lies in its enabling them to remedy certain tensions and instabilities that arise in their other coordinative, normative practices in a way that minimizes the risk of domination by alpha-type freeriders, the fracturing of social groups, and individual defection from cooperative endeavors. -/- In the final two chapters, I leverage the account to defend a pragmatist-friendly notion of objectivity in terms of a structure of distributed epistemic authority according to which no claim within a practice is ultimately authoritative or immune from challenge and to reconcile this sense of objectivity with a persistent pressure toward a kind of relativism that restricts the standing to make moral claims to members of the relevant communities.

In this chapter, I produce counterexamples to Presuppositional Epistemic Contextualism (PEC), a view about the semantics of ‘knowledge’-ascriptions that I have argued for elsewhere. According to PEC, the semantic content of the predicate ‘know’ at a context C is partly determined by the speakers’ pragmatic presuppositions at C. The problem for the view that I shall be concerned with here arises from the fact that pragmatic presuppositions are sometimes known to be true by the speakers who make (...) them: hence the Problem of Known Presuppositions. After discussing several unsuccessful ways to solve the problem, I propose the addition of a new Lewisian rule of proper ignoring to the semantics of PEC--namely, the Rule of Evidence-Based Ignoring. If the proposed account succeeds, the Problem of Known Presuppositions has a straightforward solution within the framework of PEC. (shrink)

“Objectivity” is an important theoretical concept with diverse applications in our collective practices of inquiry. It is also a concept attended in recent decades by vigorous debate, debate that includes but is not restricted to scientists and philosophers. The special authority of science as a source of knowledge of the natural and social world has been a matter of much controversy. In part because the authority of science is supposed to result from the objectivity of its methods and results, (...) objectivity has been described as an “essentially contested,” and even an “embattled” concept. The concept of objectivity has important but contested applications outside of scientific practices as well. Philosophers, psychologists, and theologians debate whether there is an objective basis for ethical claims and demands. Legal scholars debate what it would mean for laws to be objectively derivable from basic assumptions about justice and equality. One aim of this book is to guide readers through the often volatile debates over the nature and value of objectivity. Another aim is to contribute to that debate through articulating the domain-variance of norms of objectivity, and their different functions for inquirers. A better understanding of the underdetermination problem, and of the many ways that "epistemic" and "social" values rub shoulders in the course of inquiry, aids the development of my pragmatic pluralist account of objectivity.

Many philosophers favour the simple knowledge account of assertion, which says you may assert something only if you know it. The simple account is true but importantly incomplete. I defend a more informative thesis, namely, that you may assert something only if your assertion expresses knowledge. I call this 'the express knowledge account of assertion', which I argue better handles a wider range of cases while at the same time explaining the simple knowledge account's appeal. §1 (...) introduces some new data that a knowledge account of assertion well explains. §2 explains the simple knowledge account's advantage over two of its main competitors. §3 presents a problem for the simple account and offers a solution, which is to adopt the express knowledge account. §4 encapsulates the case for the express knowledge account, and offers a unifying vision for the epistemology of belief and assertion. §5 answers an objection. §6 briefly sums up. Even those who ultimately reject my conclusion can still benefit from the new data presented in §1, and learn an important lesson from the problem discussed in §3, which demonstrates a general constraint on an acceptable account of the norm of assertion.

Background: Despite being often taken as the benchmark of quality for diagnostic and classificatory tools, 'validity' is admitted as a poorly worked out notion in psychiatric nosology. Objective: Here we aim at presenting a view that we believe to do better justice to the significance of the notion of validity, as well as at explaining away some misconceptions and inappropriate expectations regarding this attribute in the aforementioned context. Method: The notion of validity is addressed taking into account its role, the (...) framework according to which it should be assessed and the specific contents to which it refers within psychiatric nosology. Results and Conclusions: The notion of validity has an epistemological thrust and its foremost role is distinguishing correct reasoning and truth from what is irrational or false. From it follows not only that 'validity' always refers to elements of knowledge and rationality such as arguments, inferences and propositions, but also that the appropriate frameworks to assess 'validity' are logics and scientific methodology. When the validity of a psychiatric diagnostic category is at stake, the contents to which it refers are those relevantly related to the notion of 'diagnostic concept'. The consequences of our reading on the notion of 'validity' are discussed vis-à-vis the challenges faced by psychiatric nosology in order to have its diagnostic categories validated. (shrink)

The threshold problem is the task of adequately answering the question: “Where does the threshold lie between knowledge and lack thereof?” I start this paper by articulating two conditions for solving it. The first is that the threshold be neither too high nor too low; the second is that the threshold accommodate the significance of knowledge. In addition to explaining these conditions, I also argue that it is plausible that they can be met. Next, I argue that many (...) popular accounts of knowledge cannot meet them. In particular, I lay out a number of problems that standard accounts of knowledge face in trying to meet these conditions. Finally, near the end of this paper, I argue that there is one sort of account that seems to evade these problems. This sort of account, which is called a cluster account of knowledge, says that knowledge is to be accounted for in terms of truth, belief and a cluster of epistemic properties and also that knowledge doesn’t require having all members of the cluster, but merely some subset.
