If there is any consensus about knowledge in contemporary epistemology it is that there is one primary kind: knowledge-that. I put forth a view, one I find in the works of Aristotle, on which instead knowledge-of - construed in a fairly demanding sense as being well-acquainted with things - is the primary kind. As to knowledge-that, it is not something distinct from knowledge-of, let alone more fundamental, but instead a species. To know (...) that such-and-such, just like to know a person or place, is to be well-acquainted with a portion of reality - in this case a fact. In part by comparing classic Gettier cases to cases in which one has true impressions of but fails to know a person, I argue that this account not only respects our intuitions about knowledge-that - in particular that it is or entails non-accidentally true justified belief - but also explains them, providing a compelling analysis.

Norström has argued that contemporary epistemological debates about the conceptual relations between knowledge-that and knowledge-how need to be supplemented by a concept of technological knowledge—with this being a further kind of knowledge. But this paper argues that Norström has not shown why technological knowledge-that is so distinctive because Norström has not shown that such knowledge cannot be reduced conceptually to a form of knowledge-how. The paper thus applies practicalism (...) to the case of technological knowledge-that. Indeed, the paper shows why Norström’s conception of technological knowledge unintentionally strengthens this proposed form of reduction. (shrink)

This work approaches the distinction between knowledge-how and knowledge-that in terms of two complementary concepts: performance and information. In order to do so, I formulate Ryle’s argument of infinite regress in terms of performance in order to show that Stanley and Williamson’s counterargument has no real object: both reject the view that the exercise of knowledge-that necessarily requires the previous consideration of propositions. Next, using the concept of feedback, I argue that Stanley (...) and Williamson’s positive account of knowledge-how in terms of knowledge-that corresponds to the output of the comparison between an intention of action and the perceived outcome of performance. Then, I expound other theories of mind and cognition in which feedback and prediction play a fundamental role in order to explain other ways in which information intervenes in performance—i.e., information is construed as knowledge-that available at subject level that guides performance. Finally, I present some reflections on the impact of the concept of knowledge-how, and possible routes to continue our enquiry on the nature of knowledge. (shrink)

In this article I have two primary goals. First, I present two recent views on the distinction between knowledge-that and knowledge-how (Stanley and Williamson, The Journal of Philosophy 98(8):411–444, 2001; Hetherington, Epistemology futures, 2006). I contend that neither of these provides conclusive arguments against the distinction. Second, I discuss studies from neuroscience and experimental psychology that relate to this distinction. Having examined these studies, I then defend a third view that explains certain relevant data (...) from these studies by positing the double dissociation of knowledge-that and knowledge-how and that is also able to do explanatory work elsewhere. (shrink)

Skilful expertise is grounded in practical, performative knowledge-how, not in detached, spectatorial knowledge-that, and knowledge-how is embodied by habitual dispositions, not representation of facts and rules. Consequently, as action control is a key requirement for the intelligent selection, initiation, and regulation of skilful performance, habitual action control, i.e. the kind of action control based on habitual dispositions, is the true hallmark of skill and the only veridical criterion to evaluate expertise. Not only does this imply (...) class='Hi'>that knowledge-that does not make your actions more skilful, but it also implies that it makes them less skilful. This thesis, that I call Radical Habitualism, finds a precursor in Hubert Dreyfus. His approach is considered extreme by most philosophers of skill & expertise: an agent –says Dreyfus– does not perform like an expert when they lack the embodied dispositions necessary to control their action habitually or when they stop relying on such dispositions to control their actions. Thus, one cannot perform skilfully if their actions are guided by representations (isomorphic schemas, explicit rules, and contentful instructions), as the know-that that they convey disrupts or diminishes the agent’s habitual engagement with the task at hand. In defence of Radical Habitualism, I will argue that only the contentless know-how embedded in habitual dispositions fulfils (i) the genetic, (ii) the normative, and (iii) the epistemic requirements of skilful performance. I will examine the phenomenological premises supporting Dreyfus’ approach, clarify their significance for a satisfactory normative and explanatory account of skilful expertise, and rebut the most common objections raised by both intellectualists and conciliatory habitualists, concerning hybrid actions guided by a mix of habitual and representational forms of control. In revisiting Dreyfus anti-representationalist approach, I will particularly focus on its epistemological implications, de-emphasizing other considerations related to conscious awareness. (shrink)

I first argue why Stanley and Williamson fail to eliminate the distinction between knowledge-that and knowledge-how. Then I argue that knowledge-how consists in a special kind of ways of thinking of ways of engaging in actions. So the distinction between knowledge-that and knowledge-how is twofold: the objects of knowledge-that and knowledge-how are different; the ways in which we entertain the object of knowledge are also distinct when we have (...) knowledge-that and knowledge-how. At the end, I consider two recent intellectualist efforts on knowledge-how and show why they fail. (shrink)

In his comprehensive survey of the contemporary debate over scientific progress in philosophy of science, Rowbottom observes that philosophers of science have mostly relied on interpretations of historical cases from the history of science and intuitions elicited by hypothetical cases as evidence for or against philosophical accounts of scientific progress. Only a few have tried to introduce empirical evidence into this debate, whereas most others have resisted the introduction of empirical evidence by claiming that doing so would reduce (...) the debate to empirical studies of science. In this paper, I set out to show how empirical evidence can be introduced into the scientific progress debate. I conduct a corpus-based, quantitative study whose results suggest that there is a positive linear relationship between _knowledge that_ talk and _knowledge how_ talk in scientific articles. These results are contrary to Niiniluoto’s view according to which there is a clear distinction between scientific progress and technological progress such that _knowledge that_ belongs to the former, whereas _knowledge how_ belongs to the latter.

I exist. That is something I know. Most philosophers think that Descartes was right that each of us knows that we exist. Furthermore most philosophers agree with Descartes that there is something special about how we know it. Agreement ends there. There is little agreement about exactly what is special about this knowledge. I shall present an account that is in some respects Cartesian in spirit, although I shall not pursue interpretive questions very (...) far. On this account, I know that I exist a priori; and I shall advance an explanation of how this a priori knowledge is possible and actual. I then consider the question of whether the belief that I exist is justified and, if so, how. I argue that the situation is different in important ways from the knowledge that I exist. (shrink)

The paper deals with the question of the structure of knowledge and the precise relationship between propositional "knowledge that" and dispositional "knowledge how." In the first part of my essay, I provide an analysis of the term 'knowing how' and argue that the usual alternatives in the recent epistemological debate – knowing how is either a form of propositional or dispositional knowledge – are misleading. In fact it depends on the semantic and pragmatic context (...) of the usage of this term whether 'knowing how' refers to a type of dispositional knowledge, to propositional knowledge, or to a hybrid form of both. Only in the first case, can one say that dispositional know how cannot be reduced to any form of propositional knowledge. Yet, this case is the most interesting one to consider in the investigation of the nature of knowledge, if one assumes that knowing that p presupposes "having found out that p." Having found something out, however, presupposes certain acts of epistemic inquiry and corresponding epistemic abilities. Examined more carefully, it is shown that the dispositional knowledge-how is a necessary condition for propositional knowledge-that, hence propositional knowledge-that is a species of the dispositional knowledge-how. Accordingly, dispositional knowledge has to be understood as being at the very core of our notion of knowledge, including propositional knowledge. (shrink)

An overview of philosophical work on the distinction between knowledge how and knowledge that, focusing on what it means to say that they are 'distinct', and on what is at stake in the debate between intellectualists and anti-intellectualists about knowledge how.

Overgaard, Timmermans, Sandberg, and Cleeremans ask if the conscious experience of people in implicit learning experiments can be explored more fully than just confidence ratings allow. We show that confidence ratings play a vital role in such experiments, but are indeed incomplete in themselves: in addition, use of structural knowledge attributions and ratings of fringe feelings like familiarity are important in characterizing the phenomenology of the application of implicit knowledge.

Studies have recently begun to attend to the ways paid labor is embodied. However, the literature on embodied labor has not adequately addressed occupations for which the site of labor is the worker’s own body. One such occupation is that of gynecological educators—female-bodied instructors who teach breast and pelvic examinations to medical students using their own bodies as models. Drawing on interviews with current and former gynecological educators and professional directors, I ask how workers use their bodies to produce (...) legitimated forms of knowledge and how workers navigate gendered meanings attached to bodies. Gynecological educators use a distancing technique I call strategic dualism, which draws on using constructions of the body as an object while simultaneously relying on subjective experiences. This technique allows them to maintain their knowledge and authority, and suggests that workers are able to selectively draw on gendered meanings about the female body to pursue their goals.

In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius. Upon closer inspection, the ideal of the genius relies on the topos of the experience of knowledge presented in Heisenberg's memoir from Der Teil und das Ganze. Gespräche im Umkreis (...) der Atomphysik. This article discusses the influence of this topos on his biographies. The article first contextualizes Heisenberg's popular science texts among his academic career and the cultural contexts of the German Bildungsbürgertum. Second, it focuses on the aesthetic repertoire of knowledge production as the experience of knowledge. By going beyond the semantic level, it is shown that the topos of the experience of nature in Heisenberg's memoir is central to his scientific persona. Ultimately, the idea of the genius stands in a longue durée of German Romanticism and natural philosophy is shown to shape the masculinities and scientific personae of the modern physicist. (shrink)

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

Amygdala is an intensively researched brain structure involved in social processing and multiple major clinical disorders, but its functions are not well understood. The functions of a brain structure are best hypothesized on the basis of neuroanatomical connectivity findings, and of behavioral, neuroimaging, neuropsychological and physiological findings. Among the heaviest neuroanatomical interconnections of amygdala are those with perirhinal cortex (PRC), but these are little considered in the theoretical literature. PRC integrates complex, multimodal, meaningful and fine-grained distributed representations of objects and (...) conspecifics. Consistent with this connectivity, amygdala is hypothesized to contribute meaningful and fine-grained representations of intangible knowledge for integration by PRC. Behavioral, neuroimaging, neuropsychological and physiological findings further support amygdala mediation of a diversity of such representations. These representations include subjective valence, impact, economic value, noxiousness, importance, ingroup membership, social status, popularity, trustworthiness and moral features. Further, the formation of amygdala representations is little understood, and is proposed to be often implemented through embodied cognition mechanisms. The hypothesis builds on earlier work, and makes multiple novel contributions to the literature. It highlights intangible knowledge, which is an influential but insufficiently researched factor in social and other behaviors. It contributes to understanding the heavy but neglected amygdala-PRC interconnections, and the diversity of amygdala-mediated intangible knowledge representations. Amygdala is a social brain region, but it does not represent species-typical social behaviors. A novel proposal to clarify its role is postulated. The hypothesis is also suggested to illuminate amygdala’s involvement in several core symptoms of autism spectrum disorder (ASD). Specifically, novel and testable explanations are proposed for the ASD symptoms of disorganized visual scanpaths, apparent social disinterest, preference for concrete cognition, aspects of the disorder’s heterogeneity, and impairment in some activities of daily living. Together, the presented hypothesis demonstrates substantial explanatory potential in the neuroscience, social and clinical domains. (shrink)

A growing number of epistemologists have endorsed the Ignorance Norm for Inquiry. Roughly, this norm says that one should not inquire into a question unless one is ignorant of its answer. I argue that, in addition to ignorance, proper inquiry requires a certain kind of knowledge. Roughly, one should not inquire into a question unless one knows it has a true answer. I call this the Knowledge Norm for Inquiry. Proper inquiry walks a fine line, holding (...) knowledge that there is an answer in the left hand and ignorance of the answer in the right. (shrink)

A central conclusion developed and defended throughout the book is that epistemic autonomy is necessary for knowledge (both knowledge-that and knowledge-how) and in ways that epistemologists have not yet fully appreciated. The book is divided into five chapters. Chapter 1 motivates (using a series of twists on Lehrer’s TrueTemp case) the claim that propositional knowledge requires autonomous belief. Chapters 2 and 3 flesh out this proposal in two ways, by defending a specific (...) form of history-sensitive externalism with respect to propositional knowledge-apt autonomous belief (Chapter 2) and by showing how the idea that knowledge requires autonomous belief—understood along the externalist lines proposed—corresponds with an entirely new class of knowledge defeaters (Chapter 3). Chapter 4 extends the proposal to (both intellectualist and anti-intellectualist) knowledge-how and performance enhancement, and in a way that combines insights from virtue epistemology with research on freedom, responsibility, and manipulation. Chapter 5 concludes with a new twist on the Value of Knowledge debate, by vindicating the value of epistemically autonomous knowledge over that which falls short, including (mere) heteronomous but otherwise epistemically impeccable justified true belief.

Reductive intellectualists (e.g., Stanley & Williamson 2001; Stanley 2011a; 2011b; Brogaard 2008; 2009; 2011) hold that knowledge-how is a kind of knowledge-that. For this thesis to hold water, it is obviously important that knowledge-how and knowledge-that have the same epistemic properties. In particular, knowledge-how ought to be compatible with epistemic luck to the same extent as knowledge-that. It is argued, contra reductive intellectualism, that knowledge-how is compatible with (...) a species of epistemic luck which is not compatible with knowledge-that, and thus it is claimed that knowledge-how and knowledge-that come apart. (shrink)

Cognitive integration is a defining yet overlooked feature of our intellect that may nevertheless have substantial effects on the process of knowledge-acquisition. To bring those effects to the fore, I explore the topic of cognitive integration both from the perspective of virtue reliabilism within externalist epistemology and the perspective of extended cognition within externalist philosophy of mind and cognitive science. On the basis of this interdisciplinary focus, I argue that cognitive integration can provide a minimalist yet adequate (...) epistemic norm of subjective justification: so long as the agent’s belief-forming process has been integrated in his cognitive character, the agent can be justified in holding the resulting beliefs merely by lacking any doubts there was something wrong in the way he arrived at them. Moreover, since both externalist philosophy of mind and externalist epistemology treat the process of cognitive integration in the same way, we can claim that epistemic cognitive characters may extend beyond our organismic cognitive capacities to the artifacts we employ or even to other agents we interact with. This move is not only necessary for accounting for advanced cases of knowledge that is the product of the operation of epistemic artifacts or the interactive activity of research teams, but it can further lead to interesting ramifications both for social epistemology and philosophy of science.

What is knowledge? How hard is it for a person to have knowledge? Good Knowledge, Bad Knowledge confronts contemporary philosophical attempts to answer those classic questions, offering a theory of knowledge that is unique in conceiving of knowledge in a non-absolutist way.

It is commonly assumed that besides knowledge of facts or truths, there is also knowledge of things–for example, we say that we know people or know places. We could call this "objectual knowledge". In this paper, I raise doubts about the idea that there is a sui generis objectual knowledge that is distinct from knowledge of truths.

By around the age of 5½, many children in the United States judge that numbers never end, and that it is always possible to add 1 to a set. These same children also generally perform well when asked to label the quantity of a set after one object is added (e.g., judging that a set labeled “five” should now be “six”). These findings suggest that children have implicit knowledge of the “successor function”: Every natural number, (...) n, has a successor, n + 1. Here, we explored how children discover this recursive function, and whether it might be related to discovering productive morphological rules that govern language‐specific counting routines (e.g., the rules in English that represent base‐10 structure). We tested 4‐ and 5‐year‐old children’s knowledge of counting with three tasks, which we then related to (a) children’s belief that 1 can always be added to any number (the successor function) and (b) their belief that numbers never end (infinity). Children who exhibited knowledge of a productive counting rule were significantly more likely to believe that numbers are infinite (i.e., there is no largest number), though such counting knowledge was not directly linked to knowledge of the successor function, per se. Also, our findings suggest that children as young as 4 years of age are able to implement rules defined over their verbal count list to generate number words beyond their spontaneous counting range, an insight which may support reasoning over their acquired verbal count sequence to infer that numbers never end.

In the article I consider whether philosophical anthropology offers knowledge about man. I begin with a definition of knowledge, then I present philosophical anthropology against the background of other kinds of anthropology. Having explained what is proper to it, I show that its goal cannot be the attainment of knowledge. Knowledge has requirements that an unreduced philosophical anthropology cannot fulfill; reduction deprives it of what is proper to it. However, the fact that it (...) does not produce knowledge is not a defect. The goal of my article is to create a common arena for considering various different approaches to man; this requires that the various parties admit that man cannot be reduced to what can be known about him. In order to know something, it is necessary to use carefully selected methods; it is not the case that merely saying something about man implies the possession of knowledge about him. (shrink)

In Self-Knowledge and Resentment, Akeel Bilgrami argues that self-knowledge of our intentional states is special among all the knowledges we have because it is not an epistemological notion in the standard sense of that term, but instead is a fallout of the radically normative nature of thought and agency. Four themes or questions are brought together into an integrated philosophical position: What makes self-knowledge different from other forms of knowledge? What makes for freedom and (...) agency in a deterministic universe? What makes intentional states of a subject irreducible to its physical and functional states? And what makes values irreducible to the states of nature as the natural sciences study them? This integration of themes into a single and systematic picture of thought, value, agency, and self-knowledge is essential to the book's aspiration and argument. Once this integrated position is fully in place, the book closes with a postscript on how one might fruitfully view the kind of self-knowledge that is pursued in psychoanalysis. (shrink)

Traditional philosophical discussions of knowledge have focused on the epistemic status of full beliefs. In this book, Moss argues that in addition to full beliefs, credences can constitute knowledge. For instance, your .4 credence that it is raining outside can constitute knowledge, in just the same way that your full beliefs can. In addition, you can know that it might be raining, and that if it is raining then it is probably cloudy, (...) where this knowledge is not knowledge of propositions, but of probabilistic contents. -/- The notion of probabilistic content introduced in this book plays a central role not only in epistemology, but in the philosophy of mind and language as well. Just as tradition holds that you believe and assert propositions, you can believe and assert probabilistic contents. Accepting that we can believe, assert, and know probabilistic contents has significant consequences for many philosophical debates, including debates about the relationship between full belief and credence, the semantics of epistemic modals and conditionals, the contents of perceptual experience, peer disagreement, pragmatic encroachment, perceptual dogmatism, and transformative experience. In addition, accepting probabilistic knowledge can help us discredit negative evaluations of female speech, explain why merely statistical evidence is insufficient for legal proof, and identify epistemic norms violated by acts of racial profiling. Hence the central theses of this book not only help us better understand the nature of our own mental states, but also help us better understand the nature of our responsibilities to each other.

There are two competing views of knowledge-how: Intellectualism and anti-intellectualism. According to the reductionist varieties of intellectualism defended by Jason Stanley and Timothy Williamson (2001) and Berit Brogaard (2007, 2008, 2009), knowledge-how simply reduces to knowledge-that. To a first approximation, s knows how to A iff there is a w such that s knows that w is a way to A. For example, John knows how to ride a bicycle if and only if there (...) is a way w such that John knows that w is a way to ride a bicycle. John Bengson and Marc Moffett (2007) defend an anti-reductionist version of intellectualism which takes knowledge-how to require, in addition, that s understand the concepts involved in her belief. According to the anti-intellectualist accounts originally defended by Gilbert Ryle (1946) and many others after him, knowledge-how requires the possession of a practical ability and so knowing that w (for some w) is a way to A does not suffice for knowing-how. For example, John knows how to ride a bicycle only if John has the ability to ride it; if John merely knows that w (for some w) is a way to ride a bicycle, John does not know how to ride a bicycle. Here I will argue for a conciliatory position that is compatible with the reductionist variety of intellectualism: knowledge-how is reducible to knowledge-that. But, I argue, there are knowledge states which are not justification-entailing and knowledge states which are not belief-entailing. Both kinds of knowledge state require the possession of practical abilities. I conclude by arguing that the view defended naturally leads to a disjunctive conception of abilities as either essentially involving mental states or as not essentially involving mental states. Only the former kind of ability is a kind of knowledge-state, viz. a knowledge-how state. (shrink)

Discussions of group knowledge typically focus on whether a group’s knowledge that p reduces to group members’ knowledge that p. Drawing on the cumulative reading of collective knowledge ascriptions and considerations about the importance of the division of epistemic labour, I argue what I call the Fragmented Knowledge account, which allows for more complex relations between individual and collective knowledge. According to this account, a group can know an answer to a question (...) in virtue of members of the group knowing parts of that answer, when the whole answer is available to group-level action. I argue that this account explains a swathe of central cases of group knowledge, as well as explaining some central features of group knowledge. (shrink)

When we affirm that someone knows something, we are making a value judgment of sorts - we are claiming that there is something superior about that person's opinion, or their evidence, or perhaps about them. A central task of the theory of knowledge is to investigate the sort of evaluation at issue. This is the first book to make 'epistemic normativity,' or the normative dimension of knowledge and knowledge ascriptions, its central focus. John Greco (...) argues that knowledge is a kind of achievement, as opposed to mere lucky success. This locates knowledge within a broader, familiar normative domain. By reflecting on our thinking and practices in this domain, it is argued, we gain insight into what knowledge is and what kind of value it has for us. (shrink)

Introspective knowledge by acquaintance is knowledge we have by being directly aware of our phenomenally conscious states. In this paper, I argue that introspective knowledge by acquaintance is a sui generis kind of knowledge: it is irreducible to any sort of propositional knowledge and is wholly constituted by a relationship of introspective acquaintance. My main argument is that this is the best explanation of some epistemic facts about phenomenal consciousness and introspection. In particular, (...) it best explains the epistemic asymmetry between a subject who has never had a certain phenomenal state and one who has. I also consider two theoretical objections to my claim: an objection from disunity and an objection from mysteriousness. I show that these objections can be answered and that introspective knowledge by acquaintance being sui generis remains a live option on the table. (shrink)

According to virtue epistemology, knowledge involves cognitive success that is due to cognitive competence. This paper explores the prospects of a virtue theory of knowledge that, so far, has no takers in the literature. It combines features from a couple of different virtue theories: like Pritchard's [forthcoming; et al. 2010] view, it qualifies as what I call an ‘impure’ version of virtue epistemology, according to which the competence condition is supplemented by an additional (safety) condition; like (...) Sosa's 2007, 2010 view, it construes the ‘because’ relation at issue in the competence condition in terms of competence manifestation. I argue that this virtue epistemology can steer clear of a number of old and new problems that arise for its rivals on both sides. (shrink)

Knowledge and Presuppositions develops a novel account of epistemic contextualism based on the idea that pragmatic presuppositions play a central role in the semantics of knowledge attributions. According to Blome-Tillmann, knowledge attributions are sensitive to what is pragmatically presupposed at the context of ascription. The resulting theory--Presuppositional Epistemic Contextualism (PEC)--is simple and straightforward, yet powerful enough to have far-reaching and important consequences for a variety of hotly debated issues in epistemology and philosophy of language. In this (...) book, Blome-Tillmann first develops Presuppositional Epistemic Contextualism and then explores its ability to resolve various sceptical paradoxes and puzzles. Blome-Tillmann also defends PEC against familiar and widely discussed philosophical and linguistic objections to contextualism. In the final chapters of the book PEC is employed to illuminate a variety of concerns central to contemporary discussions of epistemological issues, such as Gettier cases, Moorean reasoning, the nature of evidence, and other current problems and puzzles.
