This essay provides a novel argument for impurism, the view that certain non-truth-relevant factors can make a difference to a belief's epistemic standing. I argue that purists, unlike impurists, are forced to claim that certain ‘high-stakes’ cases rationally require agents to be akratic. Akrasia is one of the paradigmatic forms of irrationality. So purists, in virtue of calling akrasia rationally mandatory in a range of cases with no obvious precedent, take on a serious theoretical cost. By focusing on (...) akrasia, and on the nature of the normative judgments involved therein, impurists gain a powerful new way to frame a core challenge for purism. They also gain insight about the way in which impurism is true: my argument motivates the claim that there is moral encroachment in epistemology. (shrink)

That knowledge ascriptions exhibit some form of sensitivity to context is uncontroversial. How best to account for the context-sensitivity at issue, however, is the topic of heated debates. A certain version of nonindexical contextualism seems to be a promising option. Even so, it is incumbent upon any contextualist account to explain in what way and to what extent the epistemic standard operative in a particular context of epistemic evaluation is affected by non-epistemic factors. In this paper, I (...) investigate how non-epistemic factors come into play when knowledge is ascribed. I argue that knowledge ascriptions often serve the purpose of providing actionable information. This, in turn, requires that epistemic interests be balanced against non-epistemic interests. Moreover, it raises the question of whose interests matter, those of the ascriber, the addressee, or the subject of ascription. Eventually, an answer to the question is suggested. (shrink)

We propose a logic of knowledge for impure simplicial complexes. Impure simplicial complexes represent distributed systems under uncertainty over which processes are still active and which processes have failed or crashed. Our work generalizes the logic of knowledge for pure simplicial complexes, where all processes are alive, by Goubault et al. Our logical semantics has a satisfaction relation defined simultaneously with a definability relation. The latter restricts which formulas are allowed to have a truth value: dead processes cannot know or (...) be uncertain about any proposition, and live processes cannot know or be uncertain about propositions involving processes they know to be dead. The logic satisfies some but not all axioms and rules of the modal logic S5. Impure simplicial complexes correspond to Kripke models where each agent’s accessibility relation is an equivalence relation on a subset of the domain only. We also propose a notion of bisimulation for impure simplicial complexes and show bisimulation correspondence. (shrink)

The Argument from Principles, the primary motivation for impurism or pragmatic encroachment theories in epistemology, is often presented as an argument for everyone—an argument that proceeds from harmless premises about the nature of rationally permissible action to the surprising conclusion that one’s knowledge is partly determined by one’s practical situation. This paper argues that the Argument from Principles is far from neutral, as it presupposes the falsity of one of impurism’s main competitors: epistemic contextualism. As a consequence, (...) hybrid positions combining impurism and contextualism—positions that impurists have sometimes hinted at in the literature—are, while logically consistent, ill-motivated. Once the impurist embraces contextualism, the Argument from Principles can no longer get off the ground. The paper concludes that those who make use of the Argument from Principles are committed to an invariantist impurism and their case in support of impurism can only ever be as strong as their case against contextualism. Given recent contextualist work on the semantics of ‘knowledge’-attributions, this is likely to turn out problematic for the impurists. (shrink)

Purity has been recognized as an ideal of proof. In this paper, I consider whether purity continues to have value in contemporary mathematics. The topics (e.g., algebraic topology, algebraic geometry, category theory) and methods of contemporary mathematics often favor unification and generality, values that are more often associated with impurity rather than purity. I will demonstrate this by discussing several examples of methods and proofs that highlight the epistemic significance of unification and generality. First, I discuss the examples of (...) algebraic invariants and of considering a mathematical object from several different perspectives to illustrate that the methods used in contemporary mathematics favor impurity. Then I consider an example from category theory which demonstrates how unification and generality are related to impurity and that impure solutions can be explanatory. In light of this discussion, we see that purity only has marginal value within contemporary mathematics which instead prioritizes the epistemic values associated with impurity. (shrink)

Responding to critiques of Dilthey’s interpretive psychology, I revisit its relation with epistemology and the human sciences. Rather than reducing knowledge to psychology and psychology to subjective understanding, Dilthey articulated the epistemic worth of a psychology involving (1) an impure phenomenology of embodied, historically-situated, and worldly consciousness as individually lived yet complicit with its naturally and socially constituted contexts, (2) experience- and communication-oriented processes of interpreting others, (3) the use of third-person structural-functional analysis and causal explanation, and (4) a (...) recognition of the ungroundability, facticity, and conflict inherent in knowledge and life. (shrink)

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

Epistemic infinitism is the view that infinite series of inferential relations are productive of epistemic justification. Peirce is explicitly infinitist in his early work, namely his 1868 series of articles. Further, Peirce's semiotic categories of firsts, seconds, and thirds favors a mixed theory of justification. The conclusion is that Peirce was an infinitist, and particularly, what I will term an impure infinitist. However, the prospects for Peirce's infinitism depend entirely on the prospects for Peirce's early semantics, which are (...) not good. Peirce himself revised the semantic theory later, and in so doing, it seems also his epistemic infinitism. (shrink)

Abstract Epistemic infinitism is certainly not a majority view in contemporary epistemology. While there are some examples of infinitism in the history of philosophy, more work needs to be done mining this history in order to provide a richer understanding of how infinitism might be formulated internal to different philosophical frameworks. Accordingly, we argue that the philosophy of Emmanuel Levinas can be read as operating according to an ?impure? model of epistemic infinitism. The infinite obligation inaugurated by the (...) ?face to face encounter? with the Other yields an approach to the ethics of belief that accords with infinitism. This reading of Levinas brings his ethical thought into dialogue with contemporary epistemology as well as provides an historical example of infinitism within the current debates. (shrink)

I will assume here the defenses of epistemic infinitism are adequate and inquire as to the variety standpoints within the view. I will argue that infinitism has three varieties depending on the strength of demandingness of the infinitist requirement and the purity of its conception of epistemic justification, each of which I will term strong pure, strong impure, and weak impure infinitisms. Further, I will argue that impure infinitisms have the dialectical advantage.

Statistical evidence—say, that 95% of your co-workers badmouth each other—can never render resenting your colleague appropriate, in the way that other evidence (say, the testimony of a reliable friend) can. The problem of statistical resentment is to explain why. We put the problem of statistical resentment in several wider contexts: The context of the problem of statistical evidence in legal theory; the epistemological context—with problems like the lottery paradox for knowledge, epistemic impurism and doxastic wrongdoing; and the context (...) of a wider set of examples of responses and attitudes that seem not to be appropriately groundable in statistical evidence. Regrettably, we do not come up with a fully general, fully adequate, fully unified account of all the phenomena discussed. But we give reasons to believe that no such account is forthcoming, and we sketch a somewhat messier account that may be the best that can be had here. (shrink)

It is a familiar criticism of Subject-Sensitive Invariantism that the view makes incorrect predictions about cases in which the attributor of knowledge is in a high-stakes situation and the subject of the attribution in a low-stakes situation. In a recent paper in this journal, Brian Kim has argued that the mentioned type of case should be ignored, since the relevant knowledge ascriptions are inappropriate in virtue of violating an epistemic norm of presupposing. I show, pace Kim, that the mentioned (...) utterances do not carry factivity presuppositions. To this end I discuss a phenomenon known as presupposition suspension, which is widely associated with the presuppositions of epistemic factives such as know that p or discover that p. I argue further that the problem of unknown presuppositions discussed by Kim can be circumvented by slightly amending the cases at hand. In particular, I demonstrate that factivity presuppositions are unobjectionable in problem cases in which the high-stakes ascriber knows the presuppositions at issue to be true. (shrink)

In this book, Michael Blome-Tillmann offers a critical overview of the current debate on the semantics of knowledge attributions. The book is divided into five parts. Part 1 introduces the reader to the literature on 'knowledge' attributions by outlining the historical roots of the debate andproviding an in-depth discussion of epistemic contextualism. After examining the advantages and disadvantages of the view, Part 2 offers a detailed investigation of epistemic impurism, while Part 3 is devoted to a careful (...) examination of epistemic relativism and Part4 to two different types of strict invariantism. The final part of the book explores Presuppositional Epistemic Contextualism - a version of contextualism that is argued to provide a more powerful and elegant account of the semantics of 'knowledge' attributions thanmany of its competitors. A clear and precise account is provided of the main principles underlying each view and of how they aim to explain the pertinent data and resolve philosophical puzzles and challenges. The book also provides charts outlining the relations between the positions discussed andoffers suggestions for further reading. (shrink)

In recent years the social nature of scientific inquiry has generated considerable interest. We examine the effect of an epistemically impure agent on a community of honest truth seekers. Extending a formal model of network epistemology pioneered by Zollman, we conclude that an intransigently biased agent prevents the community from ever converging to the truth. We explore two solutions to this problem, including a novel procedure for endogenous network formation in which agents choose whom to trust. We contend that our (...) model nicely captures aspects of current problems in medical research and gesture at some morals for medical epistemology more generally. (shrink)

Impure Eliminativism about Categories is the idea that ontological categories are not wholly eliminable insofar as they have epistemic value to understand the nature of ordinary and scientific objects. From the perspective of Impure Eliminativism, different criticisms have been addressed to substantialist approaches in metaphysics and, in particular, to John Heil’s substance-mode two-category ontology. The aim of this paper is to contribute to this critical project by extending its scope to C. B. Martin’s substantialism. The thesis I defend is (...) that Martin’s substratum-trope two-category ontology satisfies the elimination criterion of Impure Eliminativism for ontological categories because either it is inconsistent or else it supplies a non-exhaustive and non-exclusive categorization of ordinary and scientific objects and their properties. First, I introduce Impure Eliminativism and its novel elimination criterion for ontological categories, and I survey recent criticisms of substantialism from that perspective. Second, I show that nothing satisfies Martin’s definition of substratum in a way that is consistent with Martin’s view on tropes. Third, I note that the attempts to avoid the inconsistency make the categorization supplied by Martin’s ontology either non-exhaustive or non-exclusive. I then conclude that Martin’s substratum-trope categorial system should be eliminated in accordance with the criterion of categorial elimination of Impure Eliminativism. (shrink)

In this paper, we shall describe and critically evaluate four contemporary theories which attempt to solve the problem of the infinite regress of reasons: BonJour's ‘impure’ coherentism, BonJour's foundationalism, Haack's ‘foundherentism’ and Dancy's pure coherentism. These theories are initially put forward as theories about the justification of our empirical beliefs; however, in fact they also attempt to provide a successful response to the question of their own ‘metajustification.’ Yet, it will be argued that 1) none of the examined theories is (...) successful as a theory of justification of our empirical beliefs, and that 2) they also fall short of being adequate theories of metajustification. It will be further suggested that the failure of these views on justification is not coincidental, but is actually a consequence of deeper and tacitly held problematic epistemological assumptions (namely, the requirements of justificatory generality and epistemic priority), whose acceptance paves the way towards a generalized scepticism about empirical justification.

The aim of this essay is to test the claim that epistemologists—virtue epistemologists in particular—have much to learn from virtue ethics. The essay begins with an outline of virtue ethics itself. This section concludes that a pure form of virtue ethics is likely to be unattractive, so the virtue epistemologist should examine the "impure" views of real philosophers. Aristotle is usually held up as the paradigm virtue ethicist. His doctrine of the mean is described, and it is explained how that (...) doctrine can provide a framework for an account of epistemic virtue. The conclusion of the essay is that a virtue epistemology based on analogies with virtue ethics, though well worth developing and considering, will face several challenges in fulfilling the significant promises that have been made on its behalf.

Proponents of impure moral perception claim that, while there are perceptual moral experiences, these experiences epistemically depend on a priori moral knowledge. Proponents of pure moral perception claim that moral experiences can justify independently of substantive a priori moral knowledge. Some philosophers, most notably David Faraci, have argued that the pure view is mistaken, since moral perception requires previous moral background knowledge, and such knowledge could not itself be perceptual. I defend pure moral perception against this objection. I consider two (...) ways to understand the notion of “background knowledge” that is crucial to the objection. On a reading, the claim that background knowledge is necessary for moral perception is likely false. On a second and weaker reading, the claim is true, but the background knowledge in question could be perceptual, and thus compatible with pure moral perception. Thus, the objection fails. (shrink)

What is the so-called “question of ontology?” Is the question of ontology genuinely a question about “categories” (Lowe 2006), “structure” (Sider 2011), “existence” (Thomasson 2015), or rather “reality” (Fine 2009)? In this article, I defend the neo-Sellarsian approach to the question of ontology, a novel, naturalistic approach according to which the foundational question of ontology is about “understanding the manifest and the scientific images of the world, and their multiple relationships.” First, I argue for the thesis of Impure Eliminativism, a (...) form of constructive pluralism about the question of ontology by which the substantivity of questions of ontology which are not the neo-Sellarsian one is to be built upon certain relations with the neo-Sellarsian question of ontology. Second, I argue for the categorial plasticity of the two images and their relations in connection with the hypothesis of Weak Epistemic Factualism. Third, and lastly, I argue for a person-based ontology framed in terms of the crucial notions of “fact” and “understanding” in response to the eliminativist categorizations of the two images and their relationships proposed by substantialism and structuralism.

Many philosophers have claimed that relying on the testimony of others in normative questions is in some way problematic. In this paper, I consider whether we should be troubled by deference in democratic politics. I argue that deference is less problematic in impure cases of political deference, and most non-ideal cases of political deference are impure. To establish the second point, I rely on empirical research from political psychology. I also outline two principled reasons why we should expect political deference (...) to be untroubling: political problems are difficult and require a division of epistemic labour; furthermore, there is value in exercising epistemic solidarity with those one shares an identity or interests with.

Was the zoological garden a place for science in the 19th and 20th centuries? This question cannot be answered with a simple yes or no. Rather, this Special Issue suggests, we need to reconstruct how the concrete conditions of the zoo as an institution influenced, enabled, triggered, facilitated, obstructed, or impeded scientific research. The zoo was and is a multifunctional space serving different constituencies, such as scientists of different disciplines, artists, breeders, and the general public. This collection of articles argues (...) that despite or even because of its hybrid character, the zoo generated knowledge about exotic animals in often unexpected ways. This Special Issue conceives of “science at the zoo” as a an “impure,” yet very rich epistemic constellation with its very own dynamic, tensions, and contradictions. The first part of this introduction provides a historical overview of the topic. Synthesizing the existing secondary literature, it addresses the major themes of science at the zoo: the debate among scientists about the pros and cons of research conducted in and outside the cages; the gap between the promise of doing research at the zoo and the actual practices; and the emergence of new fields of knowledge such as zoo veterinary medicine, zoo biology, and conservation science. The introduction's second part draws out the common topics that connect the eight articles of this Special Issue: the multiplicity of spaces interacting with the zoo; the broad range of historical actors, including academics, animal traders, and zoo keepers; the changing roles of the zoo-going public; and the negotiation of authority and epistemic hierarchies in producing knowledge about zoo animals. The large numbers of zoos and the long temporal range these articles cover bring the constant evolution of “science at the zoo”-and hence its intrinsic historical dimension-to the fore. (shrink)

Daniel Isaacson has advanced an epistemic notion of arithmetical truth according to which the latter is the set of truths that we grasp on the basis of our understanding of the structure of natural numbers alone. Isaacson’s thesis is then the claim that Peano Arithmetic (PA) is the theory of finite mathematics, in the sense that it proves all and only arithmetical truths thus understood. In this paper, we raise a challenge for the thesis and show how it can (...) be overcome. We introduce the concept of purity for theories of arithmetic: a theory of arithmetic is pure when it only proves arithmetical truths. Then, we argue that, under Isaacson’s thesis, some PA-provable truths—including transfinite induction claims for infinite ordinals and some consistency statements—are seemingly not arithmetical in Isaacson’s sense, and hence that Isaacson’s thesis might entail the impurity of PA. Nonetheless, we conjecture that the advocate of Isaacson’s thesis can avoid this undesirable consequence: the arithmetical nature, as understood by Isaacson, of all contentious PA-provable statements can be justified. As a case study, we explore how this is done for transfinite induction claims with infinite ordinals below ε0. To this end, we show that the PA-proof of such claims employs exclusively resources from finite mathematics, and that ordinals below ε0 are finitary objects despite being infinite. (shrink)

Scholars have failed to adequately distinguish Kant’s grades of evil: frailty (weakness of will), impurity, and depravity. I argue that the only way to distinguish them is, f irstly, to recognize that frailty is explicitly, practically irrational and not caused by any sort of self-deception. Instead, it is caused by the radical evil that Kant finds within the character of all persons. Secondly, impurity can only be understood to be self-deception either about the nature of the act itself, which results (...) in an epistemic error, or about one’s motivations for following a properly reasoned, moral conclusion, which results in a motivational error. Thirdly, depravity is self-deception about morality itself, by which the agent believes that it is morally right to follow self-love. (shrink)

K. Lehrer and J. Richard’s analysis of remembering that p is shown to be deficient, particularly because it fails to treat factual memory as an epistemic concept. Adding a requirement concerning the subject’s past justification accommodates instances of factual memory without factual knowledge, helps explain the role of justification in remembering that p, and strengthens the analysis against certain counterexamples. The paper includes an assessment of A. Cusmariu;s definition of impure memory.

One famous debate in contemporary epistemology considers whether there is always one unique, epistemically rational way to respond to a given body of evidence. Generally speaking, answering “yes” to this question makes one a proponent of the Uniqueness thesis, while those who answer “no” are called “permissivists”. Another influential recent debate concerns whether non-truth-related factors can be the basis of epistemic justification, knowledge, or rational belief. Traditional theories answer “no”, and are therefore considered “purists”. However, more recently many theorists (...) have argued to the contrary, claiming that impurist factors, such as practical stakes, can sometimes encroach or even override truth-related considerations. This paper bridges the two debates by presenting and defending what I call “Impurist Permissivism”. I support Impurist Permissivism by showing how it can resist Roger White’s famous Argument from Arbitrariness (2005). (shrink)

We will present all the mixed and impure disjoint three-valued logics based on the Strong Kleene schema. Some, but not all of them, are (inferentially) empty logics. We will also provide a recipe to build philosophical interpretations for each of these logics, and show why the kind of permeability that characterized them is not such a bad feature.

In contemporary political discussions, it is depressingly common to see people criticized for expressing impure beliefs. Moreover, those who sometimes defect from their tribe are criticized for failing to be firmly enough on the side of the angels. We consider explanations for this behavior, including its relationship to moral grandstanding. We will also argue, on both moral and epistemic grounds, in favor of a norm against “blocking the exits.” We should not use social pressure to discourage people from publicly (...) changing their minds.

Obviously, science matters to philosophy. But is philosophy also constrained by science? Naturalism is roughly the view that answers positively. However, even among proponents of naturalism, how science constrains philosophy has always been (and still is) a subject of debate. There are two basic dimensions in which the debate takes place, which give rise to two different kinds of naturalism: ontological and methodological. The former concerns what there is, while the latter deals with the methods whereby we acquire knowledge and (...) beliefs. Ontological Naturalism is loosely the view that all of what there is belongs to the natural world, where the natural world is the world described by the natural sciences. By maintaining, in turn, that the ultimate structure of the world is what the natural sciences say it to be, it is to some extent close to Physicalism, according to which what most fundamentally exist are the entities and properties posited by basic physics. On the other hand, methodological naturalism is often thought of as making an epistemological claim akin to scientism—the claim that the best (perhaps the unique) approach to acquiring knowledge is that of natural sciences. Accordingly, it holds that the very same methods used to arrive at scientific theories are the only legitimate ones to be employed by philosophy.Each of these horns of naturalism implies important consequences for our understanding of the relationship between science and many areas of philosophy, including metaphysics. From the methodological point of view, naturalism might be said to entail the denial that our conception of reality needs to include whatever is exclusively accessible to metaphysical theorizing (or to “first philosophy”), understood as a distinct mode of inquiry that lacks ties to the results and practices of the sciences. Indeed, methodological naturalism is usually assumed to reject the project of a priori theorizing, and it is perhaps hard to see how the traditional metaphysics, as well as current analytical metaphysics, might be in the business of developing and assessing synthetic theories of the world supported by a posteriori evidence. From the ontological point of view, naturalism sees science as already giving us a full account of everything, including our place within that picture. Despite this, the debate around the nature of metaphysics remains very much alive (and complex), spreading its influence all across philosophy and our view of the world. The upshot is that much of metaphysical work is nowadays motivated by the naturalist desire to accommodate what the natural sciences have taught us about the world. This special issue stems exactly from the ongoing debate between naturalist and non-naturalist metaphysicians and aims to assess the prospects of naturalized projects in metaphysics and their relationships to traditional metaphysics.Are science and metaphysics separable enterprises? Should allowable metaphysical theories be constrained by and continuous with natural sciences? Does successful scientific research presuppose metaphysics? These are some of the questions addressed in the contributions comprising this special issue. In response, most of them undertake theoretical commitments of a general naturalist stamp, others challenge their philosophical cogency, while still others discuss and contrast the various versions of naturalism that are currently at the center of many metaphysical debates—which often involve some mixture of the two above-mentioned ones, in different proportions. As a result, this special issue hopes to represent the state of the art drawn from different perspectives, helping somehow to clarify extent and ongoing work in metaphysics with respect to the challenges posed by naturalist thinking and eventually to pave the way for future developments and discussions.The issue opens with Don Ross's paper “A flexible, sloppy blob? Ontology, AI, and the role of metaphysics.” In it, Ross defends a naturalized metaphysics that, in contrast with traditional metaphysical projects, is driven directly by fundamental physics. Therefore, since fundamental physics is taken to be the authoritative source of knowledge on the general structure of the universe, metaphysics should neither be separated from nor transcend it. In particular, he rejects more recent works on building metaphysical foundations for applied ontology—e.g., metaphysics for the foundations of AI—as somehow apt to vindicate the value of analytic metaphysics for the edifice of human knowledge. At the same time, however, he points out how his naturalist (methodological) naturalist approach neither incorporates nor implies a physicalistic reduction.Ferdinando Ceravolo and Steven French, in their contribution “What is a Naturalized Principle of Composition?” also support the project of a methodologically naturalized metaphysics. They focus on Van Inwagen's General Composition Question (GCQ). Specifically, they address the issue concerning whether GCQ could be underpinned by principles that are found to be naturalistically acceptable—that is, constrained and informed by advanced physical knowledge. Arguing positively, they outline two candidates for naturalistically accredited principles of composition and explore the various costs of choosing between them.Along the same lines, in his essay “Naturalism and the Question of Ontology,” Javier Cumpa argues for a naturalistic approach in metaontology based on the project of Wilfrid Sellars. He proposes a naturalistic criterion of relational substantivity for ontological questions, which is held to be naturalistic insofar as it relies on the epistemic value and the degree of understanding of the world in line with science that those questions provide us. Cumpa's view is certainly methodologically naturalist, however, although ontologically he does not seem to be committed to metaphysical notions such as ontological categories, he endorses what he calls an “Impure Eliminativism about Categories.”A more straightforward version of eliminativism is advocated by Otávio Bueno in his chapter “Dispensing with Facts, Substances, and Structures.” He contends that, even though ontological categories (i.e., structures, substances, and facts) play a central role in metaphysical theorizing, we do not need to be committed to their existence. Unlike metaphysical realists – who see true thought or assertion as adequately shaped in terms of the correct representation of completely thought and/or language independent bits of reality – he accounts for metaphysical discourse by offering a naturalist account of the linguistic practice that govern it, but without the ontological commitments that realism recommends. Nevertheless, by dropping realism he does not aim to drop metaphysics as an important form of understanding the world. In order to qualify metaphysical judgements as meaningful, he explores and invokes a distinctive deflationary strategy. The result is a view that takes metaphysical discourse literally but without ontologically inflationary maneuvers.The same deflationary strategy is pursued by Anjan Chakravartty in his piece “Last Chance Saloons for Natural Kind Realism.” But rather than on ontological categories in general, he focuses on natural kinds, arguing against realist views that contend for their mind-independent existence. Nevertheless, he shows how a deflationary approach to kinds, while rejecting kind realism, can be integrated with broader realist doctrines such as scientific realism. That is, we need not be committed to either the existence of these posits or with the metaphysically inflationary interpretations that support them in order to invoke these items in scientific theorizing and to vindicate as objective or mind-independent the truth or falsity of scientific as well as everyday claims about natural kinds.In contrast to the previous standpoints, in her article “Metaphysics as Essentially Imaginative and Aiming at Understanding,” Michaela M. McSweeney defends a non-naturalist view of metaphysics. She explores the idea that metaphysics is essentially imaginative and (at least in part) “up to us.” But treating metaphysics as essentially imaginative makes metaphysics methodologically different from scientific inquiry and more akin to art. Nevertheless, she maintains, it can still be deemed epistemologically valuable to the extent that imagination can lead to understanding. On her view, the central goal of the metaphysical project thus turns out to be understanding rather than truth.The closing paper of the issue investigates precisely the relationship between methodological naturalism and ontological naturalism. In “Methodological naturalism undercuts ontological naturalism,” Peter Forrest argues that the combination of ontological with methodological naturalism is untenable. According to his view, one way to defend ontological naturalism is to retain a version of nominalism: specifically, what he calls Redundancy Nominalism (a kind of deflationary nominalism). On the other hand, methodological naturalism requires adopting Categorial Realism. This means being a realist about universals in at least a minimal way. As a result, the fundamental description that methodological naturalism requires proves be contrary to ontological naturalism, whose precondition, in turn, is not available to methodological naturalists. This leads him to criticize ontological naturalism as a belief but, at the same time, to vindicate it as a speculation. (shrink)

For a given decision, when an undemocratic procedure would result in a good outcome, and a democratic procedure would result in a bad outcome, which decision procedure ought we to use? Epistemic democrats, such as Joseph Schumpeter, argue that all else being equal, we should prefer the procedure with the good outcome. Schumpeter’s argument for this position is that we must reject the view that only democratic procedures matter when evaluating government institutions (pure proceduralism), and the only alternative to (...) pure proceduralism that can coherently describe the relationship between democracy and the public interest is pure instrumentalism. I argue that Schumpeter’s argument for epistemic democracy does not succeed. In this paper, I outline three alternative ways of conceiving of the relationship between democracy and the public interest, which I call evaluative dualism, impure instrumentalism, and impure proceduralism. I explain how, with any of these three alternative views, we can evaluate government institutions without rejecting the intrinsic value of democratic procedures or the public interest. (shrink)

Contextualism in epistemology is the claim that the knowledge predicate is contextsensitive in the sense that it has different truth conditions across different contexts of use. Jason Stanley objects against this view that if it were correct! then "know" should be gradable in the same way as gradable adjectives. Since it lacks gradability it also lacks the postulated contextsensitivity. Or so Stanley argues. In this paper I show that the contextualist is not committed to the gradability of the knowledge predicate (...) in the first place. I will distinguish between what I will call pure threshold predicates, which either apply simpliciter or not at all in each context, and impure threshold predicates, for which context determines whether they apply simpliciter, but which can also be satisfied to certain degrees. Threshold predicates are not gradable, but many of exhibit just the kind of contextsensitivity that is postulated for "know". Pace Stanley, three claims are going to be established: that the lack of gradability of the knowledge predicate (i) does not jeopardize its contextsensitivity, (ii) does not dismantle the analogies contextualists have claimed to hold between "know" and gradable adjectives, and (iii) is perfectly consistent with the idea of varyingly high epistemic standards.

Episodic memory has a distinctive phenomenology: it involves “mentally reliving” a past event. It has been suggested that characterising episodic memory in terms of this phenomenology makes it impossible to test for in animals, because “purely phenomenological features” cannot be detected in animal behaviour. Against this, I argue that episodic memory's phenomenological features are impure, having both subjective and objective aspects, and so can be behaviourally detected. Insisting on a phenomenological characterisation of episodic memory consequently does nothing to damage the (...) prospects for detecting it in nonhuman animals. (shrink)

A notorious objection to robust virtue epistemology—the view that an agent knows a proposition if and only if her cognitive success is because of her intellectual virtues—is that it fails to eliminate knowledge-undermining luck. Modest virtue epistemologists agree with robust virtue epistemologists that if someone knows, then her cognitive success must be because of her intellectual virtues, but they think that more is needed for knowledge. More specifically, they introduce independently motivated modal anti-luck principles in their accounts to amend the (...) problem of eliminating luck—this makes their views instances of impure virtue epistemology. The aim of the paper is to argue, firstly, that such a move lacks adequate motivation; secondly, that the resulting impure accounts equally fail to handle knowledge-undermining luck. On a more positive note, these results bolster a more orthodox virtue-theoretic approach to knowledge that assigns a fundamental explanatory role to the notion of ability. In this sense, the paper also sketches an account of ability and a corresponding account of knowledge that explains how success from ability is incompatible with success from luck. (shrink)

I consider but reject one broad strategy for answering the threshold problem for fallibilist accounts of knowledge, namely what fixes the degree of probability required for one to know? According to the impurist strategy to be considered, the required degree of probability is fixed by one's practical reasoning situation. I distinguish two different ways to implement the suggested impurist strategy. According to the Relevance Approach, the threshold for a subject to know a proposition at a time is determined by the (...) practical reasoning situations she is then in to which that particular proposition is relevant. According to the Unity Approach, the threshold for a subject to know any proposition whatsoever at a time is determined by a privileged practical reasoning situation she then faces, most plausibly the highest stakes practical reasoning situation she is then in. I argue that neither way of implementing the impurist strategy succeeds and so impurism does not offer a satisfactory response to the threshold problem. (shrink)

I consider but reject one broad strategy for answering the threshold problem for fallibilist accounts of knowledge, namely what fixes the degree of probability required for one to know? According to the impurist strategy to be considered, the required degree of probability is fixed by one's practical reasoning situation. I distinguish two different ways to implement the suggested impurist strategy. According to the Relevance Approach, the threshold for a subject to know a proposition at a time is determined by the (...) practical reasoning situations she is then in to which that particular proposition is relevant. According to the Unity Approach, the threshold for a subject to know any proposition whatsoever at a time is determined by a privileged practical reasoning situation she then faces, most plausibly the highest stakes practical reasoning situation she is then in.

Cook argues that impure sets are not located. But ‘location’ is an ambiguous word and when we resolve those ambiguities it turns out that on no resolution is Cook's argument compelling.

Do epistemic requirements vary along with facts about what promotes agents' well-being? Epistemic instrumentalists say 'yes', and thereby earn a lot of contempt. This contempt is a mistake on two counts. First, it is incorrectly based: the reasons typically given for it are misguided. Second, it fails to distinguish between first- and second-order epistemic instrumentalism; and, it happens, only the former is contemptible. -/- In this book, Nathaniel P. Sharadin argues for rejecting epistemic instrumentalism as a (...) first-order view not because it suffers extensional failures, but because it suffers explanatory ones. By contrast, he argues that epistemic instrumentalism offers a natural, straightforward explanation of why being epistemically correct matters. What emerges is a second-order instrumentalist explanation for epistemic authority that is neutral between competing first-order epistemic theories. -/- Epistemic Instrumentalism Explained will be of interest to researchers and advanced students working in epistemology, ethics, and philosophy of mind.
