The Evans-Salmon position on vague identity has deservedly elicited a large response in the literature. I think it is in fact among the most provocative metaphysical ideas to appear in recent years. I will try to show in this paper, however, that the position is vulnerable to a fundamental criticism that seems to have been virtually ignored in the many discussions of it. I take the Evans-Salmon position to consist of the following two theses: Thesis I. There cannot be objects (...) x and y such that it is indeterminate whether x is (identical with) y. Thesis II. The only way for an identity sentence to be indeterminate in truth-value is if one of the expressions flanking the identity symbol is referentially ambiguous.] The argument for Thesis I is essentially as follows. We are assuming that the sense of identity under discussion satisfies the standard formal logic of identity including Leibniz's Law. Suppose, now, that it is indeterminate whether x is y. Since it is determinate that x is x, x differs from y with respect to the property of being determinately x, from which it follows by Leibniz's Law that x is not y. Since the supposition that it is indeterminate whether x is y leads to the conclusion that x is not y, this supposition is incoherent. (shrink)

The demise of behaviorism has made ethologists more willing to ascribe mental states to animals. However, a methodology that can avoid the charge of excessive anthropomorphism is needed. We describe a series of experiments that could help determine whether the behavior of nonhuman animals towards dead conspecifics is concept mediated. These experiments form the basis of a general point. The behavior of some animals is clearly guided by complex mental processes. The techniques developed by comparative psychologists and behavioral ecologists are (...) able to provide us with the tools to critically evaluate hypotheses concerning the continuity between human minds and animal minds.

Our goal in this paper is to provide enough of an account of the origins of cognitive ethology and the controversy surrounding it to help ethicists to gauge for themselves how to balance skepticism and credulity about animal minds when communicating with scientists. We believe that ethicists’ arguments would benefit from better understanding of the historical roots of ongoing controversies. It is not appropriate to treat some widely reported results in animal cognition as if their interpretations are a matter of (...) scientific consensus. It is especially important to understand why loose references to “cognitive ethology” by philosophers can signal ignorance of the field to scientists who are more deeply immersed in the relevant literature. Understanding the variety of approaches to cognitive phenomena in animals is essential if such capacities are to form the foundation of scientifically-informed ethical reasoning about animals.

There is an active debate within the field of phonology concerning the cognitive status of substantive phonetic factors such as ease of articulation and perceptual distinctiveness. A new framework is proposed in which substance acts as a bias, or prior, on phonological learning. Two experiments tested this framework with a method in which participants are first provided highly impoverished evidence of a new phonological pattern, and then tested on how they extend this pattern to novel contexts and novel sounds. Participants (...) were found to generalize velar palatalization (e.g., the change from [k] as in keep to [t⌢∫S] as in cheap) in a way that accords with linguistic typology, and that is predicted by a cognitive bias in favor of changes that relate perceptually similar sounds. Velar palatalization was extended from the mid front vowel context (i.e., before [e] as in cape) to the high front vowel context (i.e., before [i] as in keep), but not vice versa. The key explanatory notion of perceptual similarity is quantified with a psychological model of categorization, and the substantively biased framework is formalized as a conditional random field. Implications of these results for the debate on substance, theories of phonological generalization, and the formalization of similarity are discussed. (shrink)

Donald Griffin has suggested that cognitive ethologists can use communication between non-human animals as a "window" into animal minds. Underlying this metaphor seems to be a conception of cognition as information processing and communication as information transfer from signaller to receiver. We examine various analyses of information and discuss how these analyses affect an ongoing debate among ethologists about whether the communicative signals of some animals should be interpreted as referential signals or whether emotional accounts of such signals are adequate. (...) We discuss the food-calling behavior of a group of rhesus monkeys to develop these issues. (shrink)

Knowledge and Reality brings together a selection of Colin McGinn's philosophical essays from the 1970s to the 1990s, whose unifying theme is the relation between the mind and the world. McGinn defends a realist view, but emphasises the epistemological problems that come with it. He has written a new postscript to each essay, placing it in its philosophical context and offering his current reflections on the topic.

Frege maintains that there are not two distinct acts, assertion and denial; rather, denying p is one and the same as asserting not-p. Wittgenstein appears not to recognise this identity in Frege, attributing to him the contrary view that a proposition may have one of two verbs, "is true" or "is false". This paper explains Wittgenstein’s attribution as a consequence of Frege’s treatment of content as theoretically prior to the act of judgment. Where content is prior to judgment, the denial (...) of p—what is rejected in asserting p—is distinct from the assertion of not-p. Wittgenstein’s own embrace of Frege’s identity is then considered, an embrace explained in part by his repudiation of Frege’s theoretical order. (shrink)

Chemical engineering - as a recognised skill in the workplace, as an academic discipline, and as an acknowledged profession - is scarcely a century old. Yet from a contested existence before the First World War, chemical engineering had become one of the 'big four' engineering professions in Britain, and a major contributor to Western economies, by the end of the twentieth century. The subject had distinct national trajectories. In Britain - too long seen as shaped by American experiences - the (...) emergence of recognised chemical engineers was the result of professional aspirations and contingency, and shaped by a shifting ecology of institutions, firms and government. Drawing upon extensive archival research, this book examines the evolution of technical practice, working environment and social interactions of chemical engineering. It will be of considerable interest to historians, sociologists of the professions, and to practitioners themselves. (shrink)

This article explores how scientists adapt to a changing climate. To do this, we bring examples from a case study of salmon habitat restorationists in the Columbia River Basin into conversation with concepts from previous work on change and stability in knowledge infrastructures and scientific practice. In order to adapt, ecological restorationists are increasingly relying on predictive modeling tools, as well as initiating broader changes in the interdisciplinary nature of the field of ecological restoration itself. We explore how the field (...) of ecological restoration is shifting its conceptual gaze from restoring to past, historic baselines to anticipating a no-analog future and consider what this means in terms of understanding the adaptive capacity of knowledge infrastructures and epistemic communities more broadly. We argue that identifying how scientists themselves conceptualize drivers of change and respond to these changes is an important step in understanding what adaptive capacity in science might entail. We offer these examples as a provocation for thinking about “adaptive epistemologies” and how adaptation by scientists themselves can facilitate or hinder particular environmental or sociotechnical futures.

Some of the problem areas in which British philosophers of science have recently been engaged are described and some of the major contributions noted. Two sets of problems are given special attention: one concerned with the analysis of probability statements and one concerned with the appraisal of scientific theories. Three traditions in the approach to this second set of problems are distinguished. These might be called the Carnapian, the Popperian and the Wittgensteinian traditions.

In challenging the implications of my putative counter‐example to Wittgenstein's claim that “It's on the tip of my tongue” (TT) is not the expression of an experience (cf. Philosophical Investigations, p.219)1, Professor Slater writes2 … the obvious way in which to meet the threat to the adequacy of (b1) [which is that the speaker should believe that he may be able to produce the missing word (fairly soon)] is to claim that the utterer of “It's on the tip of my (...) tongue” must not merely believe that he may recall the word fairly soon, he must also believe, i.e., not rule out the possibility that, he may do so without any treatment, i.e., without being prompted by an external source such as cues, pills, or shock, (p.51).

Dans le cadre d'une réflexion sur l'expérience de la vérité, l'évocation de la crise moderniste rappelle ou précise des enjeux dont l'acuité explique, pour une part, la convocation du Concile Vatican Il. Sans nier les « avancées salutaires » de ce concile, l'auteur pose en point de départ de sa réflexion la question : Peut-on dire que le concile n'a pas empêché le retour au sein de l'Église catholique d'un « antimodernisme » ? Examinant tour à tour le rapport de (...) la vérité révélée et de la méthodologie scientifique, le problème du pluralisme dans l'Église catholique et le rapport entre dogme et herméneutique, il aboutit à une réflexion sur ce qui constitue aujourd'hui, et constituera de plus en plus, la situation du chrétien par rapport à la vérité de sa propre foi qu'il expérimentera dans un monde interreligieux; ce qui ne peut que confirmer une inévitable tension: « L'expérience effective de la vérité est celle d'une recherche méthodique, mais elle est aussi celle de l'acquiescement à un don. »In the realm of a reflection on the experience of truth, the evocation of the modernist crisis is brought to mind and focuses on what is at stake, the acuteness which explains, for one thing, the convocation of Vatican Council II. Without denying the « salutary advances » of that council, the author begins his reflection with the question : « Can one say that the council did not forestall the return, in the heart of the Catholic Church, to an «anti modernism» ? The author examines one after the other the relationship of revealed truth and scientific methodology, the problem of pluralism in the Catholic Church, and the relationship between dogma and hermeneutics. He arrives at a reflection on that which constitutes today, and will constitute more and more, the situation of the Christian in relation to the truth of his own faith, which he will experience in an irreligious world. This can only confirm an inevitable tension : «The effective expe7ience of the truth is that of a methodological research, but is also that of accepting a gift». ». (shrink)

Robert Nozick, in what is surely one of the most intriguing and provocative footnotes in modern philosophical writing, referred in Anarchy,StateandUtopia to the notion of a In keeping with the central arguments of that text, his suggestion was that choices about the genetic composition of future generations should, as far as possible, be left in the hands of private individuals, and should not be determined or restricted by the state. This free market in genetic screening would meet and would possess (...)

Recently, the effort to counter Fake News faced a counter attack: academic »postmodernism « and »social constructivism« it was said—because they say that facts are soaked in prior interpretations—are either purveyors of Fake News or set the cultural context in which it flourishes. They do so by undermining confidence in inquiry governed by simple facts. That is erroneous, argues William E. Connolly, because postmodernism never said that facts or objectivity are ghostly, subjective or »fake«. However, that what was objective at (...) one time may become less so at a later date through the combination of a paradigm shift in theory, new powers of perception, new tests with refined instruments, and changes in natural processes such as species evolution. But the emergence of new theories and tests does not reduce objectivity to subjective opinion. Facts are real. Objectivity is important. But as you move up the scale of complexity with respect to facts and objectivity, it becomes clear that what was objective at one time may become subjective at another. Not because of Fake News or postmodernism. But because the complex relationships between theory, evidence and conduct periodically open up new thresholds. Colin Lang in turn rhetorically asks if »fake news« or »alternative facts« are a new carnival and Trump its dog and pony show? The idea of »fake news« and »alternative facts« as a carnival could not only help to see the constructedness of the media spectacle, but also provides a new perspective on Trump as an actor who is playing a particular role in this carnival, and that role is not one that any of us would describe as presidential. Many in the popular press have assumed it is just what it looks like, an infantilized narcissist, a parody of some Regan-era New York real estate tycoon straight out of a Bret Easton Ellis novel. The problem is that this description is all too obvious, and misses something fundamental about alternative facts, and the part that Trump is playing. A central assumption is, then, that the creation of alternative facts is one symptom of a more structural, paradigmatic shift in the persona of a president, one which has few correlates in the annals of political history. The closest analogy for his kind of performance is actually hinted at in the title of Trump’s greatest literary achievement: The Art of the Deal. Trump is playing the part of an artist, pilfering from the tactics of the avant-garde and putting them to very different ends. (shrink)

A picture agrees with reality or fails to agree; it is correct or incorrect, true or false. What does this agreement consist in, if not in the fact that what is evidence in these language games speaks for our proposition?. The purpose of this paper is to outline a constructivist account of the notion of sense and to indicate why such an account is to be preferred to that given by classical semantics.
