Notwithstanding the many strengths of the dynamic developmental theory, there remain challenges to be overcome before it can be incorporated into a true causal model of attention-deficit/hyperactivity disorder (ADHD). These include the development of reliable measures of reinforcement delay gradients, the validation of shortened reinforcement delay as an endophenotype, and the integration of this pathway with other potential pathways.

I might summarize this section by saying that the English tenses, according to this analysis, form quite a motley group. PAST, PRES and FUT serve to relate reference time to speech time, while WOULD and USED-TO behave like Priorian operators, shifting the point of evaluation away from the reference time. HAVE also shifts the point of evaluation away from the reference time, but in a more complicated way. And FUT, in contrast to PRES and PAST, is a substitution operator, putting (...) the reference time of its clause in the plate of the speech time of subordinate clauses. (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)

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, between learning that takes place with versus without concurrent awareness, and between learning that involves the encoding of instances 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 is predominantly based on rule abstraction is questionable. When subjects cannot report the “implicitly learned” 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)

This book puts forward a radical, unorthodox thesis with respect to the Anthropocene, the philosophy of Deleuze/Guattari and education. This book analyses the Anthropocene for its unconscious drives and develops a parallel mode of education and social change.

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)

Over the past decade or so, several commentators have called for mission-driven research programs on solar geoengineering, also known as solar radiation management (SRM) or climate engineering. Building on the largely epistemic reasons offered by earlier commentators, this paper argues that a well-designed mission-driven research program that aims to evaluate solar geoengineering could promote justice and legitimacy, among other valuable ends. Specifically, an international, mission-driven research program that aims to produce knowledge to enable well-informed decision-making about solar geoengineering could (1) (...) provide a more effective way to identify and answer the questions that policymakers would need to answer; and (2) provide a venue for more efficient, effective, just, and legitimate governance of solar geoengineering research; while (3) reducing the tendency for solar geoengineering research to exacerbate international domination. Thus, despite some risks and limitations, a well-designed mission-driven research program offers one way to improve the governance of solar geoengineering research relative to the ‘investigator-driven’ status quo.

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.

Larry Hardin has been the most steadfast and influential critic of physicalist theories of color over the last 20 years. In their modern form these theories originated with the work of Smart and Armstrong in the 1960s and 1970s1 and Hardin appropriately concentrated on their views in his initial critique of physicalism.2 In his most recent contribution to this project3 he attacks Michael Tye’s recent attempts to defend and extend color physicalism.4 Like Byrne and Hilbert5, Tye identifies color with the (...) reflecting properties of objects (“reflectance physicalism”). Specifically, the determinate and determinable colors are identified with types of reflectances. (Setting some complications aside, the reflectance of an object is the proportion of light that it reflects at each wavelength in the visible spectrum.) These reflectance types are, in the terminology of Hilbert, anthropocentric—in the terminology of Lewis6, they are not very “natural”. (shrink)

This philosophy of education paper describes a schizophrenic situation. A new airport is being planned in the locale of a university which is a Centre of Excellence of Education for Sustainable Development, and the university is a major partner. The airport involves an investment in jobs, resources, and will encourage further economic development. The planners have named the inter-connected developments around the airport as the ‘Aerotropolis’, including new university facilities. One could argue that the airport is a classic example of (...) the ‘Capitalocene’, where capital rushes into a new project, and environmental costs are ignored. This paper will execute a schizoanalytic critique of the process, from the perspective of a university education researcher caught up in the rushing flows of capital. Schizoanalysis has been chosen as the educational methodology to analyse this situation, because the researcher is part of what is happening, and is turned inside out by the designation in their region of the new airport. This paper is positioned in education between capital and the environment – it will describe from an insider’s perspective what it is like to be possessed, evacuated, sold out, and exploited by capital.

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.

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.

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.

This article asks whether enhancement can truly lead to something beyond humanity, or whether it is, itself, an inherently human act. The ‘posthuman’ is an uncertain proposition. What, exactly, would one be? Many commentators suggest it to be an endpoint for the use of enhancement technologies, yet few choose to codify the term outright; which frequently leads to unnecessary confusion. Characterizing and contextualizing the term, particularly its more novel uses, is therefore a valuable enterprise. The abuse of the term ‘Human’, (...) especially in the context of the enhancement debate and the myriad meanings ascribed to it, could give ‘posthuman’ very different slants depending on one's assumptions. There are perhaps three main senses in which the term ‘human’ is employed: the biological, the moral, and the self-idealizing. In the first of these, ‘human’ is often conflated with Homo sapiens, and used interchangeably to denote species; in the second, ‘human’ generally refers to a community of beings which qualify as having a certain moral value; and the third, the self-idealizing sense, is more descriptive; a label denoting the qualities that make us who we are as beings, or ‘what matters about those who matter’. So, what might enhancement make us? A novel species or genus of hominid? Or, perhaps, a morally more valuable being than a regular human? Of course, there's a third option: that a posthuman is a being which embodies our self-ideal more successfully than we do ourselves – one ‘more human than human’. Which to choose? (shrink)

The actions of affect are prominent in the philosophy of Gilles Deleuze and can be broken down for the purposes of education into two roles. The first alludes to the history of philosophy and the ways in which affect has been used by Spinoza (Deleuze, 1992) Nietzsche (Deleuze, 1983) or Bergson (Deleuze, 1991). In this role, Deleuze reinvigorates and challenges definitions of affect that would place them into systems of understanding that could take paths to metaphysics or to becoming paradigms (...) for capture in any further theorisation of affect. For example, scholars might attest to the use of affect as defined by Spinoza in the Ethics. Deleuze (1983, 1991, 1992) attends to the ways in which scholarly understanding of affect has been broached in order to free the idea up for empirical studies and also to show that the power of didactic language may be subsumed and subverted. The second role of affect in the work of Deleuze comes about in his first two co-authored books that he produced with Félix Guattari (Deleuze & Guattari, 1984, 1988). These publications have a distinct purpose from the scholarly work, which this article shall examine in terms of educational activism, group identities and the sociology of education. This level imbues the use of language in pedagogic acts with an intense affective resonance and the multiple traces of becoming that might be present in any teaching and learning context. (shrink)

David Law's new book deals with Kierkegaard's `apophaticism' - or those elements of Kierkegaard's thought which emphasize the incapacity of human reason and the hiddenness of God.

This is the best overview of Foucault's work to date. A principal architect of poststructuralism, Michel Foucault reshaped the varied disciplines of history, philosophy, literary theory, and social science. David Shumway has provided, for the nonspecialist, a systematic analysis of the works of Foucault that is both thorough and accessible. Shumway connects Foucault's various conceptual and linguistic techniques to the basic critical strategies and purpose of his philosophy.

Time pressure has been shown to have a negative impact on ethical decision-making. This paper uses an experimental approach to examine the impact of an antecedent of time pressure, whether it is anticipated or not, on participants’ perceptions of unethical behaviour. Utilising 60 business school students at an Australian university, we examine the differential impact of anticipated and unanticipated time deadline pressure on participants’ perceptions of the likelihood of unethical behaviour occurring. We find the perception of the likelihood of unethical (...) behaviour occurring to be significantly reduced when time pressure is anticipated rather than unanticipated. The implications of this finding for both professional service organisations and tertiary institutions are considered. (shrink)

Based on a series of lectures delivered in 1840, Thomas Carlyle’s_ On Heroes, Hero-Worship, and the Heroic in History_ considers the creation of heroes and the ways they exert heroic leadership. From the divine and prophetic to the poetic to the religious to the political, Carlyle investigates the mysterious qualities that elevate humans to cultural significance. By situating the text in the context of six essays by distinguished scholars that reevaluate both Carlyle’s work and his ideas, David Sorensen and (...) Brent Kinser argue that Carlyle's concept of heroism stresses the hero’s spiritual dimension. In Carlyle’s engagement with various heroic personalities, he dislodges religiosity from religion, myth from history, and truth from “quackery” as he describes the wondrous ways in which these “flowing light-fountains” unlock the heroic potential of ordinary human beings.

Bermúdez's case for rational framing effects, while original, is unconvincing and gives only parenthetical treatment to the problematic assumptions of extensional and semantic equivalence of alternative frames in framing experiments. If the assumptions are false, which they sometimes are, no valid inferences about “framing effects” follow and, then, neither do inferences about human rationality. This commentary recaps the central problem.

The significance of counterfactual thinking in the causal judgement process has been emphasized for nearly two decades, yet no previous research has directly compared the relative effect of thinking counterfactually versus factually on causal judgement. Three experiments examined this comparison by manipulating the task frame used to focus participants' thinking about a target event. Prior to making judgements about causality, preventability, blame, and control, participants were directed to think about a target actor either in counterfactual terms (what the actor could (...) have done to change the outcome) or in factual terms (what the actor had done that led to the outcome). In each experiment, the effect of counterfactual thinking did not differ reliably from the effect of factual thinking on causal judgement. Implications for research on causal judgement and mental representation are discussed. (shrink)

In this paper, we examine the logics of essence and accident and attempt to ascertain the extent to which those logics are genuinely formalizing the concepts in which we are interested. We suggest that they are not completely successful as they stand. We diagnose some of the problems and make a suggestion for improvement. We also discuss some issues concerning definability in the formal language.

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.

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.
