This commentary asks the reader to examine Pylyshyn's target article and the imagery debate at four levels of analysis – institutional, programmatic, empirical, and individual. It is proposed that the debate follows somewhat generic patterns of discourse at all four levels, but the discourse associated with one side of the debate may or may not be expressible and evaluated in terms of the other. The different sides of the debate might better serve cognitive science if they proceed as separate research (...) programs in their respective sub-disciplines. A more inclusive program could result, however, if the opposing approaches could somehow unite. (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)

Intuitively, choices seem to be intentional actions but it is difficult to see how they could be. If our choices are all about weighing up reasons then there seems no room for an additional intentional act of choice. Richard Holton has suggested a solution to this puzzle, which involves thinking of choices in a two systems of cognition framework. Holton’s suggestion does solve the puzzle, but has some unsatisfactory consequences. This paper wants to take over the important insights from Holton (...) on the phenomenology of choice and the possible explanation via a two systems framework, but wants to suggest an alternative more satisfactory account. This account is built around the idea that choices are what Pamela Hieronymi calls managerial acts. After developing the claim the paper then defends it against the objection that managerial control cannot be understood in a system1 context, by examining recent research on uncertainty monitoring and early forms of metacognition.

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- (...) class='Hi'>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.

In the wake of Clark and Chalmers famous argument for extended cognition some people have argued that willpower equally can extend into the environment (e.g. Heath and Anderson in The thief of time: philosophical essays on procrastination. Oxford University Press, New York, pp 233–252, 2010). In a recent paper Fabio Paglieri (Consciousness in interaction: the role of the natural and social context in shaping consciousness. John Benjamins, Amsterdam, pp 179–206, 2012) provides an interesting argument to the effect that there might (...) well be extended self control, but that willpower does not lend itself to extension. This paper argues that Paglieri is right in claiming that previous attempts to extend the will are flawed. It then provides an argument for extending the will that does not fall foul of Paglieri’s argument and actually provides us with an even stronger case for extension than the one that Clark and Chalmers provide for cognition.

The paper takes a closer look at the role of knowledge and evidence in legal theory. In particular, the paper examines a puzzle arising from the evidential standard Preponderance of the Evidence and its application in civil procedure. Legal scholars have argued since at least the 1940s that the rule of the Preponderance of the Evidence gives rise to a puzzle concerning the role of statistical evidence in judicial proceedings, sometimes referred to as the Problem of Bare Statistical Evidence. While (...) this puzzle has led to the development of a multitude of accounts and approaches in the legal literature, I argue here that the problem can be resolved fairly straightforwardly within a knowledge-first framework.

Readers are awaiting a new encounter with stories united under the common title Why We Are in Need of Tales. Let me remind you that these deep philosophical books were written by Maria daVenza Tillmanns, a professional philosopher dedicated to the study of philosophizing with children, who has gained valuable experience in this field. Maria’s books are inspired by her work with her students at El Toyon Elementary School in National City (California), with whom Maria held philosophy with children classes (...) for three years before COVID-19. With parental permission, the children provided their drawings, which are used as illustrations for the books. I read Why We Are in Need of Tales, Part III with great pleasure. The focus of this book is on making decisions, sometimes very hard decisions. In Part II, the focus is on dreams — hopes and wishes we have for life. This book looks at how we may best decide how to make those hopes and wishes come true. And the answer Huk and Tuk suggest is deceptively easy: by making decisions “with your eyes wide open.” (5, p. ix). The author of this excellent book managed to describe how to make decisions with your eyes wide open through the playful dialogue between Huk and Tuk. The books are written in dialogue so the reader immediately plunges into the context of a lively conversation. Dialogue not only sharpens attention, but also invites the reader to participate in the conversation. In this way, the reader becomes a listener at the same time. (shrink)

The most prominent arguments for scepticism in modern epistemology employ closure principles of some kind. To begin my discussion of such arguments, consider Simple Knowledge Closure (SKC): (SKC) (Kxt[p] ∧ (p → q)) → Kxt[q].1 Assuming its truth for the time being, the sceptic can use (SKC) to reason from the two assumptions that, firstly, we don’t know ¬sh and that, secondly, op entails ¬sh to the conclusion that we don’t know op, where ‘op’ and ‘sh’ are shorthand for ‘ordinary (...) proposition’ and ‘sceptical hypothesis’ respectively. (SKC), however, fails for familiar reasons: since knowledge entails belief (KB), we can derive the falsity (F) from (SKC) by hypothetical syllogism, and thus reduce (SKC) to absurdity: (KB) Kxt[p] → Bxt[p]. (F) (Kxt[p] ∧ (p → q)) → Bxt[q]. (shrink)

This article addresses and resolves an epistemological puzzle that has attracted much attention in the recent literature—namely, the puzzle arising from Moorean anti-sceptical reasoning and the phenomenon of transmission failure. The paper argues that an appealing account of Moorean reasoning can be given by distinguishing carefully between two subtly different ways of thinking about justification and evidence. Once the respective distinctions are in place we have a simple and straightforward way to model both the Wrightean position of transmission failure and (...) the Moorean position of dogmatism. The approach developed in this article is, accordingly, ecumenical in that it allows us to embrace two positions that are widely considered to be incompatible. The paper further argues that the Moorean Puzzle can be resolved by noting the relevant distinctions and our insensitivity towards them: once we carefully tease apart the different senses of ‘justified’ and ‘evidence’ involved, the bewilderment caused by Moore’s anti-sceptical strategy subsides.

The current use of citation-based metrics to evaluate the research output of individual researchers is highly discriminatory because they are uniformly applied to authors of single-author articles as well as contributors of multi-author papers. In the latter case, these quantitative measures are counted, as if each contributor were the single author of the full article. In this way, each and every contributor is assigned the full impact-factor score and all the citations that the article has received. This has a multiplication (...) effect on each contributor's citation-based evaluative metrics of multi-author articles, because the more contributors an article has, the more undeserved credit is assigned to each of them. In this paper, I argue that this unfair system could be made fairer by requesting the contributors of multi-author articles to describe the nature of their contribution, and to assign a numerical value to their degree of relative contribution. In this way, we could create a contribution-specific index of each contributor for each citation metric. This would be a strong disincentive against honorary authorship and publication cartels, because it would transform the current win-win strategy of accepting honorary authors in the byline into a zero-sum game for each contributor.

This paper argues against the intuition that willpower and so called ‘tying to the mast’ strategies are fundamentally different types of mental actions to achieve self control. The argument for this surprising claim is that at least on the most plausible account of willpower an act of willpower consists in an intentional mental action that disables the mental agent and thereby creates a mental tie. The paper then defends this claim against the objection that tying to the mast strategies do (...) not have the same phenomenology as real willpower and that they do not preserve reason responsiveness.

It is commonly assumed in the philosophical literature that in order to acquire an intention, the agent has to settle a question of what to do in practical deliberation. Carruthers, P. has recently used this to argue that the acquisition of intentions can never be conscious even in cases where the agent asserts having the intention in inner speech. Because of that Carruthers also believes that knowledge of intentions even in first person cases is observational. This paper explores the challenge (...) Carruthers’ argument throws up for accounts that also rely on the notion of settling a question for intention acquisition, but who also want to maintain at the same time that knowledge of intentions in the first person case is not observational.

Recent attempts to resolve the Paradox of the Gatecrasher rest on a now familiar distinction between individual and bare statistical evidence. This paper investigates two such approaches, the causal approach to individual evidence and a recently influential (and award-winning) modal account that explicates individual evidence in terms of Nozick's notion of sensitivity. This paper offers counterexamples to both approaches, explicates a problem concerning necessary truths for the sensitivity account, and argues that either view is implausibly committed to the impossibility of (...) no-fault wrongful convictions. The paper finally concludes that the distinction between individual and bare statistical evidence cannot be maintained in terms of causation or sensitivity. We have to look elsewhere for a solution of the Paradox of the Gatecrasher. (shrink)

A long-standing position in philosophy, law, and theology is that a person can be held morally responsible for an action only if they had the freedom to choose and to act otherwise. Thus, many philosophers consider freedom to be a necessary condition for moral responsibility. However, empirical findings suggest that this assumption might not be in line with common sense thinking. For example, in a recent study we used surveys to show that – counter to positions held by many philosophers (...) – lay people consider actions to be free when they are spontaneous rather than being based on reasons. In contrast, responsibility is often considered to require that someone has thought about the alternative options. In this study we use an online survey to directly test to which degree lay judgements of freedom and responsibility match. Specifically, we test whether manipulations of deliberation affect freedom and responsibility judgements in the same way. Furthermore, we also test the dependency of these judgements on a person’s belief that their decision had consequences for their personal life. We find that people are generally considered to be more responsible for their actions than they are considered free, across most of the conditions tested. Furthermore, we found that deliberation had an opposite effect on freedom and responsibility judgements. People were considered more free when they acted spontaneously, whereas they were considered more responsible when they deliberated about their actions. These results seem to suggest that deliberating about reasons is crucially important for the lay concept of responsibility, while it is not obviously …. (shrink)

Humans seem special, because they are able to think about thinking (to make their mentality the object of their thoughts). In this paper I distinguish two very different ways in which thinking about thinking could be understood and which role these understandings play in the control of the mind. I argue on the one hand that language enables humans to express and attend to the content of their thoughts. This is an incredibly powerful tool which allows for the intentional manipulation (...) of content. On the other hand, however, this form of thinking about thinking does not require the agent to understand mental states as states and because of that it does not allow for the intentional targeting of the states. Only a second and metarepresentation based form of thinking about thinking allows for this control. the rest of the paper then discusses the possible function of the intentional control of the mind in future directed self control.

Shared leadership is not only about individual team members engaging in leadership, but also about team members adopting the complementary follower role. However, the question of what enables team members to fill in each of these roles and the corresponding influence of formal leaders have remained largely unexplored. Using a social network perspective allows us to predict both leadership and followership ties between team members based on considerations of implicit leadership and followership theories. From this social information processing perspective, we (...) identify individual team members’ political skill and the formal leaders’ empowering leadership as important qualities that facilitate the adoption of each the leader and the follower role. Results from a social network analysis in a R&D department with 305 realized leadership ties support most of our hypotheses. (shrink)

Research in psychology clearly shows that implicit biases contribute significantly to our behaviour. What is less clear, however, is whether we are responsible for our implicit biases in the same way that we are responsible for our explicit beliefs. Neil Levy has argued recently that explicit beliefs are special with regard to the responsibility we have for them, because they unify the agent. In this paper we point out multiple ways in which implicit biases also unify the agent. We then (...) examine Levy’s claim that the assertibility of explicit beliefs means that they have a unique way of unifying the agent by being available for syntactical operations. We accept that syntactical operations are important, but worry that they are less straightforwardly connected to the unification of agents than Levy claims. (shrink)

Understanding and controlling our minds is one of the most fascinating features of human cognition. It has often been assumed that this ability requires a theoretical understanding of psychological states. This assumption has recently been put under pressure by so called mindshaping approaches. We agree that these approaches provide us with a new way of self-understanding and that they enable a very powerful form of self-regulation which we label narrative control. However, we insist that there still is a crucial role (...) for a theoretical understanding of psychological states in human cognition. We argue that this is because a theoretical understanding is necessary for all intentional control of the mind. Keywords: mindreading; mindshaping; narrative control; manipulative control; folk psychology. (shrink)

Epistemic agency is a crucial concept in many different areas of philosophy and the cognitive sciences. It is crucial in dual process theories of cognition as well as theories of metacognition and mindreading, self-control, and moral agency. But what is epistemic agency? The Tinkering Mind argues that epistemic agency has two distinct and incompatible definitions. It can be simply understood as intentional mental action, or as a distinct non-voluntary form of evaluative agency. The core argument of the book demonstrates that (...) both definitions lead to surprising and counterintuitive consequences. If epistemic agency is a form of intentional action, then this implies that the radical theory of extended cognition has to be true. If, on the other hand, epistemic agency is not intentional action but evaluative agency, then intentional epistemic actions like deliberation are not truly cognitive but merely catalytic. Once established, the distinction between these two options sheds new light on various and diverse philosophical and psychological debates from dual process theories to debates on choice and self-control.

A number of prominent epistemologists claim that the principle of sensitivity “play[s] a starring role in the solution to some important epistemological problems”. I argue that traditional sensitivity accounts fail to explain even the most basic data that are usually considered to constitute their primary motivation. To establish this result I develop Gettier and lottery cases involving necessary truths. Since beliefs in necessary truths are sensitive by default, the resulting cases give rise to a serious explanatory problem for the defenders (...) of sensitivity accounts. It is furthermore argued that attempts to modally strengthen traditional sensitivity accounts to avoid the problem must appeal to a notion of safety—the primary competitor of sensitivity in the literature. The paper concludes that the explanatory virtues of sensitivity accounts are largely illusory. In the framework of modal epistemology, it is safety rather than sensitivity that does the heavy explanatory lifting with respect to Gettier cases, lottery examples, and other pertinent cases.

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)

Orthodoxy has it that language evolution requires Gricean communicative intentions and therefore an understanding of nested metarepresentations. The problem with this orthodoxy is that it is hard to see how non-linguistic creatures could have such a sophisticated understanding of mentality. Some philosophers like Bar-On (The Journal of Philosophy 110 (6): 293-330, 2013a; Mind and Language 28 (3): 342-375, 2013b) have attempted to develop a non-Gricean account of language acquisition building on the information-rich and subtle communicative powers of expressive behaviours. This (...) paper argues that this approach shares a number of instructive similarities with the literature on the cognitive conception of language. It shows how expressive accounts (and others) can learn from insights in that tradition and identifies a problem with the role of intentional actions in expressive accounts that can be solved by understanding expressive behaviours more as cognitive rather than communicative tools.

Holding content explicitly requires a form of self knowledge. But what does the relevant self knowledge look like? Using theory of mind as an example, this paper argues that the correct answer to this question will have to take into account the crucial role of language based deliberation, but warns against the standard assumption that explicitness is necessary for ascribing awareness. It argues in line with Bayne that intentional action is at least an equally valid criterion for awareness. This leads (...) to a distinction between different levels of implicitness. Postulating these different levels, it is argued, allows us to make better sense of the empirical literature on early false belief task abilities. (shrink)

Examining the naturalist and normativist concepts of health and disease this article starts with analysing the view of C. Boorse. It rejects Boorse's account of health as species-typical functioning, giving a critique of his view based on evolutionary theory of contemporary biology. Then it gives a short overview of the normativist theories of health, which can be objectivist and subjectivist theories. Rejecting the objectivist theories as philosophically untenable, it turns to the subjectivist theories of Gert and Culver, and to the (...) view of Nordenfelt. These theories give quite a good subjectivist account of health and disease, but they do not pay enough attention to the notion of the environment, without which it is impossible to define health and disease. Starting with their definitions but introducing the notion of “reasonable social norms”, the article arrives at the following definition of health: The healthier a physical or mental characteristic, process, reaction is, the more it makes it possible for the individual to adapt to reasonable social norms without pain and suffering, and the longer, and happier a life it will be able to ensure him in that society.

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)

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.

This paper explores the relationship between thinking and acting morally. Can we transfer critical thinking skills to real life situations? Philosophical practice with clients as well as with school children creates a context for not only being a critical and reflective thinker but also a self -critical thinker and self -reflective thinker. In his book On Dialogue, David Bohm explores the notion of proprioception of thinking; focusing on thinking as a movement. The tacit, concrete process of thinking informs our actions (...) in a way that rational thinking by itself cannot. We can try to impose rational thinking on our tacit, concrete process of thinking but knowing how to be just abstractly, for example, does not necessarily make us act justly in the moment. Philosophical practice puts us in touch with our own tacit, concrete process of thinking. Through dialogue (Bohm, Buber) we become more than skilled rational thinkers ; we become skilled thinking beings. (shrink)

Embodied self-reflection goes beyond strictly rational thinking – we are thinking beings after all, for it includes our tacit concrete knowledge, as Michael Polanyi and David Bohm would describe the thinking that is implicit in our abilities to know how to do things such as knowing how to ride a bicycle. Polanyi describes this knowledge as: “[knowing] more than we can tell.” To become aware of the thinking below the surface of rational thinking is very challenging. Yet that is exactly (...) what is required for any kind of self-awareness and self-transformation to take place. To become aware of our own thinking essentially means becoming aware of oneself as a witness to our own thinking in the process of thinking. Bohm understands thinking as a movement and similarly to becoming aware of our physical movements through proprioception, so too can we become aware of our thinking as a movement. Proprioception of thinking implies proprioception of embodied thinking. -/- (Self-)reflection is (self-)examination or (self-)scrutiny is a process that requires the courage to question one’s self and with it the touchstones underlying our identity. This process is a form of parrhesia, for parrhesia is essentially also a form of infinite questioning, and which can also be applied to questioning the self. (shrink)

Martin Smith has recently proposed, in this journal, a novel and intriguing approach to puzzles and paradoxes in evidence law arising from the evidential standard of the Preponderance of the Evidence. According to Smith, the relation of normic support provides us with an elegant solution to those puzzles. In this paper I develop a counterexample to Smith’s approach and argue that normic support can neither account for our reluctance to base affirmative verdicts on bare statistical evidence nor resolve the pertinent (...) paradoxes. Normic support is, as a consequence, not a successful epistemic anti-luck condition. (shrink)

This paper invokes the conceptual framework of Bourdieu to analyse the mechanisms, which help to maintain inappropriate authorship practices and the functions these practices may serve. Bourdieu’s social theory with its emphasis on mechanisms of domination can be applied to the academic field, too, where competition is omnipresent, control mechanisms of authorship are loose, and the result of performance assessment can be a matter of symbolic life and death for the researchers. This results in a problem of game-theoretic nature, where (...) researchers’ behaviour will be determined more by the logic of competition, than by individual character or motives. From this follows that changing this practice requires institutionalized mechanisms, and change cannot be expected from simply appealing to researchers’ individual conscience. The article aims at showing that academic capital is translated into honorary authorship. With little control, undetected honorary authorship gives the appearance of possessing intellectual capital. In this way a dominant position is made to be seen as natural result of intellectual ability or scientific merit, which makes it more acceptable to those in dominated positions. The final conclusion of this paper is that undemocratic authorship decisions and authorship based performance assessment together are a form of symbolic violence. (shrink)

Safety principles in epistemology are often hailed as providing us with an explanation of why we fail to have knowledge in Gettier cases and lottery examples, while at the same time allowing for the fact that we know the negations of sceptical hypotheses. In a recent paper, Sinhababu and Williams have produced an example—the Backward Clock—that is meant to spell trouble for safety accounts of knowledge. I argue that the Backward Clock case is, in fact, unproblematic for the more sophisticated (...) formulations of safety in the literature. However, I then proceed to construct two novel examples that turn out problematic for those formulations—one that provides us with a lottery-style case of safe ignorance and one that is a straightforward case of unsafe knowledge. If these examples succeed, then safety as it is usually conceived in the current debate cannot account for ignorance in all Gettier and lottery-style cases, and neither is it a necessary condition for knowledge. I conclude from these troublesome examples that modal epistemologists ought to embrace a much more simple and non-reductive version of safety, according to which the notion of similarity between possible worlds that determines in which worlds the subject must believe truly is an epistemic notion that cannot be defined or reduced to notions independent of knowledge. The resulting view is shown to also lead to desirable results with respect to lottery cases, certain quantum phenomena, and a puzzling case involving a cautious brain-in-a-vat. (shrink)

Epistemic contextualism—the view that the content of the predicate ‘know’ can change with the context of utterance—has fallen into considerable disrepute recently. Many theorists have raised doubts as to whether ‘know’ is context-sensitive, typically basing their arguments on data suggesting that ‘know’ behaves semantically and syntactically in a way quite different from recognised indexicals such as ‘I’ and ‘here’ or ‘flat’ and ‘empty’. This paper takes a closer look at three pertinent objections of this kind, viz. at what I call (...) the Error-Theory Objection, the Gradability Objection and the Clarification-Technique Objection. The paper concludes that none of these objections can provide decisive evidence against contextualism. (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)

Das Aequivalenzprinzip wurde von Einstein erst 1907 in Worte gefasst. Er wendete sich 1912 brieflich an W.
