The COVID-19 pandemic and its associated stressors have impacted the daily lives and sleeping patterns of many individuals, including university students. Dreams may provide insight into how the mind processes changing realities; dreams not only allow consolidation of new information, but may give the opportunity to creatively “play out” low-risk, hypothetical threat simulations. While there are studies that analyze dreams in high-stress situations, little is known of how the COVID-19 pandemic has impacted dreams of university students. The aim of this (...) study was to explore how the dream content of students was affected during the university COVID-19 lockdown period (March–July, 2020). Using online survey methods, we analyzed dream recall content (n= 71) using the Hall-Van de Castle dream coding system and Fisher's exact tests for sex comparisons. Preliminary results indicate that female students experienced more nightmares as compared to male students. Dream analysis found that, relative to normative American College Student (ACS) samples generated pre-COVID-19, women were more likely to experience aggressive interactions in their dream content, including increased physical aggression. Results indicate that university students did experience changes in dream content due to the pandemic lockdown period, with women disproportionally affected. These findings can aid universities in developing support programs for students by bringing forth an understanding of students' concerns and anxieties as they process the “new normal” of social distancing.

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

A number of ways of taxonomizing human learning have been proposed. We examine the evidence for one such proposal, namely, that there exist independent explicit and implicit learning systems. This combines two further distinctions, (1) between learning that takes place with versus without concurrent awareness, and (2) between learning that involves the encoding of instances (or fragments) versus the induction of abstract rules or hypotheses. Implicit learning is assumed to involve unconscious rule learning. We examine the evidence for implicit learning (...) derived from subliminal learning, conditioning, artificial grammar learning, instrumental learning, and reaction times in sequence learning. We conclude that unconscious learning has not been satisfactorily established in any of these areas. The assumption that learning in some of these tasks (e.g., artificial grammar learning) is predominantly based on rule abstraction is questionable. When subjects cannot report the rules that govern stimulus selection, this is often because their knowledge consists of instances or fragments of the training stimuli rather than rules. In contrast to the distinction between conscious and unconscious learning, the distinction between instance and rule learning is a sound and meaningful way of taxonomizing human learning. We discuss various computational models of these two forms of learning. (shrink)

Colour has often been supposed to be a subjective property, a property to be analysed orretly in terms of the phenomenological aspects of human expereince. In contrast with subjectivism, an objectivist analysis of color takes color to be a property objects possess in themselves, independently of the character of human perceptual expereince. David Hilbert defends a form of objectivism that identifies color with a physical property of surfaces - their spectral reflectance. This analysis of color is shown to provide (...) a more adequate account of the features of human color vision than its subjectivist rivals. The author's account of colro also recognises that the human perceptual system provides a limited and idiosyncratic picture of the world. These limitations are shown to be consistent with a realist account of colour and to provide the necessary tools for giving an analysis of common sense knowledge of color phenomena. (shrink)

The strongest arguments for the permissibility of geoengineering (also known as climate engineering) rely implicitly on non-ideal theory—roughly, the theory of justice as applied to situations of partial compliance with principles of ideal justice. In an ideally just world, such arguments acknowledge, humanity should not deploy geoengineering; but in our imperfect world, society may need to complement mitigation and adaptation with geoengineering to reduce injustices associated with anthropogenic climate change. We interpret research proponents’ arguments as an application of a particular (...) branch of non-ideal theory known as “clinical theory.” Clinical theory aims to identify politically feasible institutions or policies that would address existing (or impending) injustice without violating certain kinds of moral permissibility constraints. We argue for three implications of clinical theory: First, conditional on falling costs and feasibility, clinical theory provides strong support for some geoengineering techniques that aim to remove carbon dioxide from the atmosphere. Second, if some kinds of carbon dioxide removal technologies are supported by clinical theory, then clinical theory further supports using those technologies to enable “overshoot” scenarios in which developing countries exceed the cumulative emissions caps that would apply in ideal circumstances. Third, because of tensions between political feasibility and moral permissibility, clinical theory provides only weak support for geoengineering techniques that aim to manage incoming solar radiation.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:F. R. Leavis (Modern Cultural Theorists)Stephen OgdenF. R. Leavis (Modern Cultural Theorists), by Anne Samson; x & 196 pp. Toronto: University of Toronto Press, 1992, $45.00 cloth, $16.95 paper.If it is an overstatement to say that the waves of change currently disturbing the teaching of English in universities originated from the splash made by F. R. Leavis at Cambridge beginning in 1933, Anne Samson’s account of (...) the theorist’s influence scarcely admits it. Her chapter titles—“Leavis and the Growth of English Studies,” “English as a University Subject,” “Literary ‘Theory’ and Constituting the Canon”—indicate not only the range of issues connected with F. R. Leavis’s name but also his significant involvement in their genesis.Samson’s book portrays Leavis as the efficient cause in the establishment of university English as a critical, or more accurately a diagnostic, enterprise. At an early professional cost (he was denied faculty appointment at Cambridge for five years), Leavis helped cut English curricula free from philology, languages, and classical studies; a responsibility Samson partially excuses by connecting Leavis’s motivating principles back through Matthew Arnold to Dickens and Carlyle and even to one “Reverend H. J. Rose, a leading figure in the founding of King’s College, London... declaring in a sermon delivered in 1826 that literature teaches ‘the wisdom of men better and wiser than ourselves’ and prepares for the ‘examination of those moral and intellectual truths which are not only the worthiest exercise of our reason, but most concern our future destiny’” (p. 12).This moralism Samson sees as the central and redeeming principle in Leavis’s system. Specifically, she identifies the Condition of England debate—over the state of culture and economics in a “‘technologico-Benthamite world’” (p. 63)—as the key to Leavis’s literary criticism, his influential journal Scrutiny, and his wide-ranging reform endeavors. “Literature mattered to Leavis because he believed it to be the means, above all others, of combating the ills of a mechanised, constantly changing world and of restoring the heritage of those dispossessed by the machine” (p. 3).Professionally asserting the primacy of criticism over scholarship, then in his writings making no distinction between the literary and the social, Leavis ultimately refused any separation between literature and life. Samson carefully [End Page 360] traces this development in Leavis’s general theory in order to bring out its easily-overlooked implication for the social position of a literary academic. She quotes this crucial passage from Leavis: “The critic... is as much concerned with the health of the mind as any doctor with the health of the body. To set up as a critic is to set up as a judge of values... For the arts are inevitably and quite apart from any intentions of the artist an appraisal of existence” (pp. 15–16). No longer a mere scholar, or the type of irrelevant empiric Leavis so hated in the person of C. P. Snow, the Leavisite theorist is the grand physician diagnosing all society’s ills. Literary artists and their writings, so far from forming the most important part of literature, become perfectly irrelevant—“quite apart”—with the medicocritic prescribing universally “of existence.”Samson’s treatment of Leavis is analytical, though enjoyably and consistently biographical. For instance, her final, and largest, chapter shows the moralist model of the literary critic (the “judge of values”) in action by detailing the history of Leavis’s complete reversal of estimation between T. S. Eliot and D. H. Lawrence. Leavis originally gave Eliot “hero-worship” (p. 162) and dismissed Lawrence as “mechanical” (p. 157). But concurrent with Eliot’s progress to Anglo-Catholicism, Leavis’s moral judgments overturned and, true to type, he increasingly censured Eliot’s writings by diagnosing problems in the man, while he grew to idolize Lawrence; ironically for “rescuing life from... inner mechanisation” (p. 169).Such inconstancy, here expressed in every word, Samson sees as an historical mark of character which places Leavis among the “Great Men of Ideas” (p. 172).Stephen OgdenSimon Fraser UniversityCopyright © 1995 The Johns Hopkins University Press...

Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.

Climate engineering (CE), the intentional modification of the climate in order to reduce the effects of increasing greenhouse gas concentrations, is sometimes touted as a potential response to climate change. Increasing interest in the topic has led to proposals for empirical tests of hypothesized CE techniques, which raise serious ethical concerns. We propose three ethical guidelines for CE researchers, derived from the ethics literature on research with human and animal subjects, applicable in the event that CE research progresses beyond computer (...) modeling. The Principle of Respect requires that the scientific community secure the global public's consent, voiced through their governmental representatives, before beginning any empirical research. The Principle of Beneficence and Justice requires that researchers strive for a favorable risk–benefit ratio and a fair distribution of risks and anticipated benefits, all while protecting the basic rights of affected individuals. Finally, the Minimization Principle requires that researchers minimize the extent and intensity of each experiment by ensuring that no experiments last longer, cover a greater geographical extent, or have a greater impact on the climate, ecosystem, or human welfare than is necessary to test the specific hypotheses in question. Field experiments that might affect humans or ecosystems in significant ways should not proceed until a full discussion of the ethics of CE research occurs and appropriate institutions for regulating such experiments are established.

Many commentators fear that climate engineering research might lead policy-makers to reduce mitigation efforts. Most of the literature on this so-called ‘moral hazard’ problem focuses on the prediction that climate engineering research would reduce mitigation efforts. This paper focuses on a related ethical question: Why would it be a bad thing if climate engineering research obstructed mitigation? If climate engineering promises to be effective enough, it might justify some reduction in mitigation. Climate policy portfolios involving sufficiently large or poorly planned (...) reductions in mitigation, however, could lead to an outcome that would be worse than the portfolio that would be chosen in the absence of further climate engineering research. This paper applies three ethical perspectives to describe the kinds of portfolios that would be worse than that ‘baseline portfolio’. The literature on climate engineering identifies various mechanisms that might cause policy-makers to choose these inferior portfolios, but it is difficult to know in advance whether the existence of these mechanisms means that climate engineering research really would lead to a worse outcome. In the light of that uncertainty, a precautionary approach suggests that researchers should take measures to reduce the risk of mitigation obstruction. Several such measures are suggested. (shrink)

There are serious reasons for accepting each of these propositions individually but there are apparently insurmountable difficulties with accepting all three of them simultaneously if we assume that color is a single property. 1) and 2) together seem to imply that there is some property which all organisms with color vision can see and 3) seems to imply that there can be no such property. If these implications really are valid then one or more of these propositions will have to (...) be rejected in spite of whatever reasons can be given for their apparent acceptability. Before going on to discuss possible resolutions of this apparent contradiction it is worth pointing out there our three propositions are not all of a kind. Proposition 1) is a metaphysical thesis about the ontological status of color and proposition 3) is an empirical thesis about what properties organisms with color vision are capable of detecting. If you accept 1) then 2) will appear to verge on the trivial, but if 1) is denied then the status of 2) will appear more problematic. In what follows I will have more to say about why we either should or should not accept all three of these propositions. (shrink)

Stephen Gardiner argues that geoengineering does not meet the “canonical technical definition” of a global public good, and that it is misleading to frame geoengineering as a public good. A public good is something that is nonrival and nonexcludable. Contrary to Gardiner’s claims, geoengineering meets both of these criteria. Framing geoengineering as a public good is useful because it allows commentators to draw on the existing economic, philosophical, and social scientific literature on the governance of public goods.

In their recent paper ‘Why lockdown of the elderly is not ageist and why levelling down equality is wrong’ Savulescu and Cameron attempt to argue the case for subjecting the ‘elderly’ to limits not imposed on other generations. We argue that selective lockdown of the elderly is unnecessary and cruel, as well as discriminatory, and that this group may suffer more than others in similar circumstances. Further, it constitutes an unjustifiable deprivation of liberty.

If you trained someone to emit a particular sound at the sight of something red, another at the sight of something yellow, and so on for other colors, still he would not yet be describing objects by their colors. Though he might be a help to us in giving a description. A description is a representation of a distribution in a space (in that of time, for instance).

It is human nature to wonder how things might have turned out differently--either for the better or for the worse. For the past two decades psychologists have been intrigued by this phenomenon, which they call counterfactual thinking. Specifically, researchers have sought to answer the "big" questions: Why do people have such a strong propensity to generate counterfactuals, and what functions does counterfactual thinking serve? What are the determinants of counterfactual thinking, and what are its adaptive and psychological consequences? This important (...) work brings together a collection of thought-provoking papers by social and cognitive psychologists who have made important theoretical and empirical contributions to our understanding of this topic. The essays in this volume contain novel theoretical insights, and, in many cases descriptions of previously unpublished empirical studies. The Psychology of Counterfactual Thinking provides an excellent overview of this fascinating topic for researchers, as well as advanced undergraduates and graduates in psychology--particularly those with an interest in social cognition, social judgment, decision judgment, decision making, thinking and reasoning.

"Understanding Phenomenology" provides a guide to one of the most important schools of thought in modern philosophy. The book traces phenomenology's historical development, beginning with its founder, Edmund Husserl and his "pure" or "transcendental" phenomenology, and continuing with the later, "existential" phenomenology of Martin Heidegger, Jean-Paul Sartre, and Maurice Merleau-Ponty. The book also assesses later, critical responses to phenomenology - from Derrida to Dennett - as well as the continued significance of phenomenology for philosophy today. Written for anyone coming to (...) phenomenology for the first time, the book guides the reader through the often bewildering array of technical concepts and jargon associated with phenomenology and provides clear explanations and helpful examples to encourage and enhance engagement with the primary texts.

An experiment was conducted to test the effectiveness of brief instruction in information structuring (i.e., representing and integrating information) for improving the coherence of probability judgments and binary choices among intelligence analysts. Forty-three analysts were presented with comparable sets of Bayesian judgment problems before and immediately after instruction. After instruction, analysts’ probability judgments were more coherent (i.e., more additive and compliant with Bayes theorem). Instruction also improved the coherence of binary choices regarding category membership: after instruction, subjects were more likely (...) to invariably choose the category to which they assigned the higher probability of a target’s membership. The research provides a rare example of evidence-based validation of effectiveness in instruction to improve the statistical assessment skills of intelligence analysts. Such instruction could also be used to improve the assessment quality of other types of experts who are required to integrate statistical information or make probabilistic assessments. (shrink)

In Being and Time, Heidegger explicitly defers any consideration of ourselves (Dasein) as embodied. I try to account for Heidegger's reluctance to talk about 'the body' in connection with his explication of Dasein, by arguing that doing so would be at odds with the kind of investigation his 'phenomenology of everydayness' is meant to be. That Heidegger omits discussion of the body in Being and Time might lead one to think of the human body in terms of the other categories (...) Heidegger deploys: readiness-to-hand and presence-at-hand (Being and Time) and biological organisms (Fundamental Concepts of Metaphysics). I argue that any such identification ought to be resisted, as these categories serve only to deprive our bodies of their specifically human dimension. Indeed, by surveying the failure of these categories as proper to the human body, we gain further insight into Heidegger's initial deferral: only given the existential analytic can one begin to offer a proper account of ourselves in bodily terms.

David Bloor has claimed that Wittgenstein is best read as offering the beginnings of a sociological theory of knowledge, despite Wittgenstein's reluctance to view his work this way. This leads him to dismiss Wittgenstein's many self?characterizations as mere ?prejudice?. In doing so, however, Bloor misses the import of Wittgenstein's work as a ?grammatical investigation?. The problems inherent in Bloor's interpretative approach can be discerned in his attitude toward Wittgenstein's use of imaginary scenarios: he demands that they be replaced by (...) real natural history and real ethnography. This demand is misplaced. The very self?characterizations Bloor dismisses show how imaginary scenarios have a place in his philosophical project simply by being imagined. Three examples are examined and presented in such a way as to make Bloor's demand for replacement increasingly more difficult to comprehend: while in the first case, the demand seems simply beside the point, in the second and third cases, it becomes difficult to say just what would count as replacements. Wittgenstein's imaginary scenarios are thus best read not as suggestions for further empirical research, but as devices to aid in recovering the naturalness and familiarity of our concepts, which is precisely what one would expect from them as part of a grammatical investigation.

Disagreements about morally appropriate mitigation policies arise in part from implicit disagreements about the nature and moral significance of needs. One key question is what, if anything, distinguishes “needs” from “mere wants.” One approach, prominent in economics and implemented in existing integrated assessment models of climate change, rejects a hard distinction between needs and wants. An alternative approach, prominent in the philosophical literature on needs, identifies needs with the requirements for autonomous agency, which is the capacity to set and pursue (...) one’s own goals. A second key question is in what sense, if any, the satisfaction of needs should take precedence over the satisfaction of wants. Those who reject the distinction between wants and needs can say only that some desires should be weighted more heavily than others. Those who endorse the distinction can say that, given certain ethical assumptions, it is wrong to frustrate one person’s needs in order to satisfy others’ mere wants. Thus, rejecting the distinction between wants and needs tends to justify less aggressive mitigation policies, in which satisfying the so-called “wants” of present generations compensates for frustrating the so-called “needs” of future generations. Endorsing the distinction between wants and needs, along with certain ethical assumptions, tends to justify more aggressive mitigation policies. Both positions are intellectually defensible; understanding them helps illuminate disagreements over mitigation policy. (shrink)

This study provides evidence regarding the level of ethical cognition of business students at the entry to college as compared to a national norm. It also provides comparative evidence on the effects of group versus individual ethical cognition upon completion of a business ethics course.

Interpretations of Heidegger's Being and Time have tended to founder on the question of whether he is in the end a realist or an idealist, in part because of Heidegger's own rather enigmatic remarks on the subject. Many have thus depicted him as being in some way ambivalent, and so as holding on to an unstable combination of the two opposing positions. Recently, William Blattner has explained the apparent ambivalence by appealing to Kant's transcendental/empirical distinction. Although an ingenious reading of (...) Being and Time, there are a number of difficulties involved in cashing out its central claims. I argue that it fails, moreover, to capture Heidegger's avowed animus toward both realism and idealism. After criticizing Blattner's reading, I recount several features of Heidegger's ?existential analytic? of Dasein in Division I of Being and Time and connect them with his (slightly later) notion of world?entry. This latter notion provides a way of explaining how Heidegger retains a realistic conception of natural entities, while offering an overall view that cannot be identified with either realism or idealism.

Drawing on 171 in-depth interviews with physicists at universities in the United States and the UK, this study examines the narratives of 48 physicists to explain the concept of ethical ambiguity: the border where legitimate and illegitimate conduct is blurred. Researchers generally assume that scientists agree on what constitutes both egregious and more routine forms of misconduct in science. The results of this study show that scientists perceive many scenarios as ethically gray, rather than black and white. Three orientations to (...) ethical ambiguity are considered—altruism, inconsequential outcomes, and preserving the status quo—that allow possibly questionable behavior to persist unchallenged. Each discursive strategy is rationalized as promoting the collective interest of science rather than addressing what is ethically correct or incorrect. The results of this study suggest that ethics training in science should focus not only on fabrication, falsification, and plagiarism and more routine forms of misconduct, but also on strategies for resolving ethically ambiguous scenarios where appropriate action may not be clear.
