We offer thoughts on Shadmehr and Ahmed's foundational assumption that behavioral intensity (vigor) is proportional to the perceived value of outcomes driving behavior (incentives). The assumption is reasonable considering classical motivational thought and scholarship in related literatures but called into question by an influential contemporary theory of motivation by Brehm. Brehm's theory suggests that the assumption is warranted in some, but not all, performance circumstances. Furthermore, proportionality between vigor and value might be generated through a deliberative goal-setting process rather than (...) through intrinsic neural linkages. (shrink)

Two jarring results concerning the main theses of Georg Henrik von Wright's Explanation and Understanding are reached through an examination and criticism of his project. It is shown, contrary to his settled judgment both in EU and subsequently, that the schema of practical inference is a causal principle, and that it is nomological in character. But one feature of von Wright's overall analysis holds up and continues to show promise: his idea of understanding explanation. This idea combines the (...) EU account of the schema and its instantiation with the notion of an intelligible connection of these instantiating elements with one another. Here the schema is deployed in conjunction with the test of intelligible connection as one of its conditions of application. The schema, so deployed, is revisable on the basis of experiences that do not conform to what we expect them to be when they are regimented in accordance with the model of understanding explanation; thus, even though the schema is not a general law, we have a basis for characterizing it as nomological, nonetheless.

The most compelling evidence for Epstein et al.'s central thesis that adult second language acquisition is constrained by the innate cognitive structures that constrain native language acquisition would be evidence of poverty of the stimulus. Although there are studies that point to such evidence, Epstein et al.'s primary form of argumentation, targetlike performance by second-language acquiring adults, is much less convincing.

It has been claimed that the attempt to analyze know-how in terms of propositional knowledge over-intellectualizes the mind. Exploiting the methods of so-called “experimental philosophy”, we show that the charge of over-intellectualization is baseless. Contra neo-Ryleans, who analyze know-how in terms of ability, the concrete-case judgments of ordinary folk are most consistent with the view that there exists a set of correct necessary and sufficient conditions for know-how that does not invoke ability, but rather a certain sort of propositional knowledge. (...) To the extent that one’s considered judgments agree with those of the folk (or to the extent that one is unwilling to contravene widespread judgments), this constitutes a strong prima facie case against neo-Ryleanism.

The connections between science and civic culture in the Victorian period have been extensively, and intensively, investigated over the past several decades. Limited attention, however, has been paid to Irish urban contexts. Roman Catholic attitudes towards science in the nineteenth century have also been neglected beyond a rather restricted set of thinkers and topics. This paper is offered as a contribution to addressing these lacunae, and examines in detail the complexities involved in Catholic engagement with science in Victorian Belfast. The (...) political and civic geographies of Catholic involvement in scientific discussions in a divided town are uncovered through an examination of five episodes in the unfolding history of Belfast's intellectual culture. The paper stresses the importance of attending to the particularities of local politics and scientific debate for understanding the complex realities of Catholic appropriations of science in a period and urban context profoundly shaped by competing political and religious factions. It also reflects more generally on how the Belfast story supplements and challenges scholarship on the historical relations between Catholicism and science. (shrink)

Antibiotic resistance has become a problem of global scale. Resistance arises through mutation or through the acquisition of resistance gene(s) from other bacteria in a process called horizontal gene transfer (HGT). While HGT is recognized as an important factor in the dissemination of resistance genes in clinical pathogens, its role in the environment has been called into question by a recent study published in Nature. The authors found little evidence of HGT in soil using a culture‐independent functional metagenomics approach, which (...) is in contrast to previous work from the same lab showing HGT between the environment and human microbiome. While surprising at face value, these results may be explained by the lack of selective pressure in the environment studied. Importantly, this work suggests the need for careful monitoring of environmental antibiotic pollution and stringent antibiotic stewardship in the fight against resistance. (shrink)

Although eye tracking has been used extensively to assess cognitions for static stimuli, recent research suggests that the link between gaze and cognition may be more tenuous for dynamic stimuli such as videos. Part of the difficulty in convincingly linking gaze with cognition is that in dynamic stimuli, gaze position is strongly influenced by exogenous cues such as object motion. However, tests of the gaze‐cognition link in dynamic stimuli have been done on only a limited range of stimuli often characterized (...) by highly organized motion. Also, analyses of cognitive contrasts between participants have been mostly been limited to categorical contrasts among small numbers of participants that may have limited the power to observe more subtle influences. We, therefore, tested for cognitive influences on gaze for screen‐captured instructional videos, the contents of which participants were tested on. Between‐participant scanpath similarity predicted between‐participant similarity in responses on test questions, but with imperfect consistency across videos. We also observed that basic gaze parameters and measures of attention to centers of interest only inconsistently predicted learning, and that correlations between gaze and centers of interest defined by other‐participant gaze and cursor movement did not predict learning. It, therefore, appears that the search for eye movement indices of cognition during dynamic naturalistic stimuli may be fruitful, but we also agree that the tyranny of dynamic stimuli is real, and that links between eye movements and cognition are highly dependent on task and stimulus properties.

What is it to trust someone? What is it for someone to be trustworthy? These are the two main questions that this paper addresses. There are various situations that can be described as ones of trust, but this paper considers the issue of trust between individuals. In it, I suggest that trust is distinct from reliance or cases where someone asks for something on the expectation that it will be done due to the different attitude taken by the trustor. I (...) argue that the trustor takes Holton’s ‘participant stance’ and this distinguishes trust from reliance. I argue that trustworthiness is different from reliability and that an account of trustworthiness cannot be successful whilst ignoring the point that aligning trustworthiness with reliability removes the virtue from being trustworthy. On the question of what it is distinguishes trustworthiness from reliability, I argue that the distinction is in the opportunity for the trustee to act against the wishes of the trustor and the trustee’s consideration of the value of the trust that has been placed in them by the trustor.

The essay addresses the well‐known idea that there has to be a place for intuition, thought of as a kind of non‐inferential rational insight, in the epistemology of basic logic if our knowledge of its principles is non‐empirical and is to allow of any finite, non‐circular reconstruction. It is argued that the error in this idea consists in its overlooking the possibility that there is, properly speaking, no knowledge of the validity of principles of basic logic. When certain important distinctions (...) are observed, for instance that between recognising that Modus Ponenes is sound and recognising that it is proof against the competent discovery of basic counterexamples, the case for thinking that there is indeed no space for genuine recognition of the validity of Modus Ponens becomes increasingly impressive. It is argued however that, the impossibility of knowledge notwithstanding, we are, in an important sense, entitled to take it that Modus Ponens is sound and that this notion of entitlement can help break the trichotomy ‐ intuition, inference, experience ‐ which imprisons our ordinary thinking about logical knowledge.

Dummett's objections to the coherence of the strict finitist philosophy of mathematics are thus, at the present time at least, ill-taken. We have so far no definitive treatment of Sorites paradoxes; so no conclusive ground for dismissing Dummett's response — the response of simply writing off a large class of familiar, confidently handled expressions as semantically incoherent. I believe that cannot be the right response, if only because it threatens to open an unacceptable gulf between the insight into his own (...) understanding available to a philosophically reflective speaker and the conclusions available to one confined to observing the former's linguistic practice; for an observer of our linguistic practice could never justifiably arrive at the conclusion that ‘red’, ‘child’, etc., are governed by inconsistent rules. But the Sorites is not the subject of this paper. The points I hope to have made plausible are: that a generalized intuitionist position cannot be so much as formulated and that even a most local intuitionism, argued for the special case of arithmetic, is hard pressed effectively to stabilize and defend itself; that strict finitism remains the natural outcome of the anti-realism which Dummett has propounded by way of support for the intuitionist philosophy of mathematics; that it is powerfully buttressed by the ideas of the latter Wittgenstein on rule-following; and that there is no extant compelling reason to suppose that its involvement with predicates of surveyability calls its coherence into question. The correct philosophical assessment of strict finitism, and its proper mathematical exegesis, remain absolutely open, almost virgin issues. This is not a situation which philosophers of mathematics should tolerate very much longer. (shrink)

This paper explains how the notion of justification transmission can be used to ground a notion of knowledge transmission. It then explains how transmission theories can characterise schoolteacher cases, which have prominently been presented as counterexamples to transmission theories.

One recent `neologicist' claim is that what has come to be known as "Frege's Theorem"–the result that Hume's Principle, plus second-order logic, suffices for a proof of the Dedekind-Peano postulate–reinstates Frege's contention that arithmetic is analytic. This claim naturally depends upon the analyticity of Hume's Principle itself. The present paper reviews five misgivings that developed in various of George Boolos's writings. It observes that each of them really concerns not `analyticity' but either the truth of Hume's Principle or our entitlement (...) to accept it and reviews possible neologicist replies. A two-part Appendix explores recent developments of the fifth of Boolos's objections–the problem of Bad Company–and outlines a proof of the principle $N^q$, an important part of the defense of the claim that what follows from Hume's Principle is not merely a theory which allows of interpretation as arithmetic but arithmetic itself.

In this article we attempt to situate nursing within the interprofessional care team with respect to processes of ethical practice and ethical decision making. After briefly reviewing the concept of interprofessionalism, the idea of a nursing ethic as ‘unique’ within the context of an interprofessional team will be explored. We suggest that nursing’s distinct perspective on the moral matters of health care stem not from any privileged vantage point but rather from knowledge developed through the daily activities of nursing practice. (...) Because of their position vis-à-vis patients and families in everyday clinical care, nurses cultivate ethical knowledge of at least two forms: (1) relational knowledge; and (2) embodied knowledge. Through the integration of these forms of knowledge, nurses develop a unique moral perspective and can make a meaningful contribution to the realm of ethics in interprofessional care. (shrink)

: Contextualism in epistemology has been proposed both as a way to avoid skepticism and as an explanation for the variability found in our use of "knows." When we turn to contextualism to perform these two functions, we should ensure that the version we endorse is well suited for these tasks. I compare two versions of epistemic contextualism: attributor contextualism and methodological contextualism. I argue that methodological contextualism is superior both in its response to skepticism and in its mechanism for (...) changing contexts. However, methodological contextualism still faces two challenges: explaining why we are solidly committed to some contexts, and explaining why knowledge within a context is valuable. I propose virtue contextualism as a useful extension of methodological contextualism, focusing on the way that our virtues depend on our social roles. My proposed virtue contextualism retains the benefits of methodological contextualism while explaining both our commitment to particular contexts and the value of knowledge held within those contexts.

According to some theories of testimonial knowledge, testimony can allow you, as a knowing speaker, to transmit your knowledge to me. A question in the epistemology of testimony concerns whether or not the acquisition of testimonial knowledge depends on the speaker's testimony being sincere. In this paper, I outline two notions of sincerity and argue that, construed in a certain way, transmission theorists should endorse the claim that the acquisition of testimonial knowledge requires sincerity.

Ernest Sosa has recently argued that the knowledge we get from instruments and the knowledge we get from testimony is similar in important ways. Most importantly, the justification that supports it is similar in kind – both instrumental justification and justification from testimony is to be understood in terms of reliability. I argue that Sosa’s theory is problematic. Specifically, I argue that we can take certain attitudes towards people that we cannot coherently take towards instruments. This, I argue, grounds a (...) distinction between the kind of justification that testimony can make available and the kind of justification that instruments can make available. The result is that reliability cannot provide a complete explanation of the justification that testimony makes available. (shrink)

This paper objects to internalist theories of justification from testimony on the grounds that they can’t accommodate intuitions about a pair of cases. The pair of cases involved is a testimonial version of the cases involved in the New Evil Demon Argument. The role of New Evil Demon cases in motivating contemporary internalist theories of knowledge and justification notwithstanding, it is argued here that testimonial cases make an intuitive case against internalist theories of justification from testimony.

Let me begin with a reminder of the crude but intuitive distinction from which the relativistic impulse springs. Any of the following claims would be likely to find both supporters and dissenters: That snails are delicious That cockroaches are disgusting That marital infidelity is alright provided nobody gets hurt That a Pacific sunset trumps any Impressionist canvas and perhaps That Philosophy is pointless if it is not widely intelligible That the belief that there is life elsewhere in the universe is (...) justified That death is nothing to fear Disputes about such claims may or may not involve quite strongly held convictions and attitudes. Sometimes they may be tractable disputes: there may be some other matter about which one of the disputing parties is mistaken or ignorant, where such a mistake or ignorance can perhaps be easily remedied, with the result of a change of heart about the original claim; or there may be a type of experience of which one of the disputing parties is innocent, and such that the effect of initiation into that experience is, once again, a change of view.

There is now a widespread accord among philosophers that the vagueness of natural language gives rise to some particularly deep and perplexing problems and paradoxes. It was not always so. For most of the first century of analytical philosophy, vagueness was generally regarded as a marginal, slightly irritating phenomenon, —receiving some attention, to be sure, in parts of the Philosophical Investigations and in the amateur linguistics enjoyed by philosophers in Oxford in the 1950s, but best idealised away in any serious (...) theoretical treatment of meaning, understanding and valid inference. Frege, as is well known, had come to be thoroughly mistrustful of vagueness, supposing that a language fit for the purpose of articulating scientific and mathematical knowledge would have to be purified of it. Later trends in philosophical logic and semantics followed his lead, not indeed in setting about the (futile) task of expurgating vagueness from natural language but by largely restricting theoretical attention to artificial languages in whose workings vagueness was assigned no role.

According totransmissiontheories of testimony, a listener's belief in a speaker's testimony can be supported by the speaker's justification for what she says. The most powerful objection to transmission theories is Jennifer Lackey'spersistent believercase. I argue that important features about the epistemology of testimony reveal how transmission theories can account for Lackey's case. Specifically, I argue that transmission theorists should hold that transmission happens only if a listener believes a speaker's testimony based on the presumption that the speaker has justification for (...) what she says. If this does not happen in thepersistent believercase, then the case is no counterexample to transmission. If this does happen in thepersistent believercase, then there is an available framework for rejecting the idea that the listener's belief is in fact justified. (shrink)

Plato's Timaeus contains a powerful and influential myth, of the construction of the universe by a divine craftsman. A god imposes reason on necessity, to bring order from a primeval 'receptacle' of disordered matter. There results the 'child' that is the cosmos - a copy of an eternally-existing perfect model. Here eight new essays from a distinguished international cast, explore aspects of this challenging work: the principles of the mythical narrative, how the world soul and human body are formed, implications (...) for illness - mental and physical, the importance of music and harmonious proportion. Later developments are also treated: Aristotle's theory of generation, the commentary of Proclus and elements of modern evolutionary theory. (shrink)

This volume examines Rawls's theory of international justice as worked out in his controversial last book, The Law of Peoples.

Descartes made a sharp distinction between matter and mind. But he also thought that the two interact with one another. Is such interaction possible, however, without either a materialist reduction of mind to matter or an idealist (phenomenalist) reduction of matter to mind? These questions overshadow the Western tradition in metaphysics from the time of Descartes to present times. The book makes an effort to stay clear of reductivist views of the two Cartesian substances. It defends a dualistic psycho-physical parallel (...) theory which reconciles freedom of action with determinism in nature. Basic problems in perception theory are also discussed, with special emphasis on hearing and sound. Because of the intrinsic interest of the subject and the author's non-technical presentation of it, the book should appeal to all readers with a serious interest in philosophy and psychology.

§I. Anti-realism of the sort which Michael Dummett has expounded takes issue with the traditional idea that an understanding of any statement is philosophically correctly analysed as involving grasp of conditions necessary and sufficient for its truth. Many kinds of statement to which, as we ordinarily think, we attach a clear sense would have to be represented, according to this tradition, as possessing verification-transcendent truth-conditions; if true that is to say, they would be so in virtue of circumstances of a (...) type transcending our range of possible awareness. Exactly where to draw the boundaries of our possible awareness might be controversial; but there is clearly no being aware, in the relevant sense, of the kind of state of affairs which would make true a generalization of theoretical physics, an assertion about James II weight on his twenty-eighth birthday, a claim about what would have happened if Edward Heath had not sought a fresh mandate during the miners' strike, or—from your point of view—the statement that my left ear aches. In each of these kinds of case the traditional view, while granting that we cannot experience the truth-conferring states of affairs as such, would nevertheless credit us with a clear conception of the type of thing they would be. To be sure, there is then no possibility of a straightforward construal of this conception as a recognitional capacity. But the traditional view tends to conceal from itself the problematic status which the alleged grasp of truth-conditions therefore assumes by working with the picture that the ‘conception’ is indirectly recognitional, that it issues in a cluster of unproblematic recognitional capacities; in particular, the ability to recognize what is or is not good evidence for the relevant statement and the ability to recognize its logical relations to other statements.

In the paper we argue that truth-relativism is potentially hostage to a problem of exhibiting witnesses of its own truth. The problem for the relativist stems from acceptance of a trumping principle according to which there is a dependency between ascriptions of truth of an utterance and ascriptions of truth to other ascriptions of truth of that utterance. We argue that such a dependency indeed holds in the case of future contingents and the case of epistemic modals and that, consequently, (...) the relativist about these domains cannot exhibit witnesses to his relativism. In the appendix we provide some results on the relation between trumping and multi-order relativism. (shrink)

This paper argues that the form of explanation at issue in the hard problem of consciousness is scientifically irrelevant, despite appearances to the contrary. In particular, it is argued that the 'sense of understanding' that plays a critical role in the form of explanation implicated in the hard problem provides neither a necessary nor a sufficient condition on satisfactory scientific explanation. Considerations of the actual tools and methods available to scientists are used to make the case against it being a (...) necessary condition, and work by J.D. Trout that exploits psychological research on the hindsight and overconfidence biases is used to show that it is not a sufficient condition. It is argued, however, that certain intellectual and moral concerns give us good reason to still try to meet the hard problem's explanatory challenge, despite its extrascientific nature. (shrink)

When regimented in a certain natural way, the concepts of explanation and justification manifest a pattern of interrelations connected more or less systematically to their object. Besides its intrinsic interest, this pattern may give us some insight into the nature, source, and limits of the concept of argument.
