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)

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)

Written by some of the world's leading academics and professionals in the field, this collection of essays brings together two complementary views on child development - the role of society and the role of cognitive growth.

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.

One central question of climate justice is how to fairly allocate the global emissions budget. Some commentators hold that the concept of fairness is hopelessly equivocal on this point. Others claim that we need a complete theory of distributive justice to answer the question. This paper argues to the contrary that, given only weak assumptions about fairness, we can show that fairness requires an allocation that is at least as prioritarian as the equal per capita view. Since even the equal (...) per capita view is more prioritarian than is politically feasible, fairness is univocal enough for all practical purposes. (shrink)

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.

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)

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.

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.

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.

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)

This article reprints the text of a review of adam smith's "theory of moral sentiments", And presents arguments for ascribing it to david hume. Hume's subsequent criticism of what he called "the hinge" of adam smith's moral system ("viz." that "all kinds of sympathy are necessarily agreeable") is also examined, And it is argued that smith failed to appreciate the nature and extent of this criticism. It is concluded that "the hinge" of smith's novel theory is a false assumption; (...) yet without it smith cannot present a viable alternative to hume's explanation of the origin of our moral sentiments.

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)

"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.

Although the importance of literacy is widely acknowledged in society and remains at the top of the political agenda, writing has been slow to establish a place in the cognitive sciences. Olson argues that to understand the cognitive implications of literacy, it is necessary to see reading and writing as providing access to and consciousness of aspects of language, such as phonemes, words and sentences, that are implicit and unconscious in speech. Reading and writing create a system of metarepresentational concepts (...) that bring those features of language into consciousness as a subject of discourse. This consciousness of language is essential not only to acquiring literacy but also to the formation of systematic thought and rationality. The Mind on Paper is a compelling exploration of what literacy does for our speech and hence for our thought, and will be of interest to readers in developmental psychology, cognitive science, linguistics, and education.

Multiple cue probability learning studies have typically focused on stationary environments. We present three experiments investigating learning in changing environments. A fine-grained analysis of the learning dynamics shows that participants were responsive to both abrupt and gradual changes in cue-outcome relations. We found no evidence that participants adapted to these types of change in qualitatively different ways. Also, in contrast to earlier claims that these tasks are learned implicitly, participants showed good insight into what they learned. By fitting formal learning (...) models, we investigated whether participants learned global functional relationships or made localized predictions from similar experienced exemplars. Both a local (the Associative Learning Model) and a global learning model (the novel Bayesian Linear Filter) fitted the data of the first two experiments. However, the results of Experiment 3, which was specifically designed to discriminate between local and global learning models, provided more support for global learning models. Finally, we present a novel model to account for the cue competition effects found in previous research and displayed by some of our participants. (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)

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)

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.

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)

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).

The role of power and its relation to values has become a topic of growing interest in business ethics as well as in the literature of management and the sociology of organizations. Though there is more interest in the role and potential for abuse of power in corporations, the concept of power drawn from classical political theory and initial behavioral studies of power in organizations is inadequate for understanding the place, complexity and ethics of power in the corporation. Analyses of (...) power drawn from recent political theory can provide a more fine-grained and illuminating understanding of power than has been available from classical political theory and social science literature. I distinguish three approaches: the behavioral model commonly employed, the ideological model which comes out of the political theory of certain neo-Marxists, and what I call the disciplinary model drawn form Michel Foucault's analysis of modern forms of power. I suggest areas of working life and ethical issues about the relation between power and values that can be illuminated by these alternate analyses. (shrink)

Previous research suggests that early performance of amnesic individuals in a probabilistic category learning task is relatively unimpaired. When combined with impaired declarative knowledge, this is taken as evidence for the existence of separate implicit and explicit memory systems. The present study contains a more fine-grained analysis of learning than earlier studies. Using a dynamic lens model approach with plausible learning models, we found that the learning process is indeed indistinguishable between an amnesic and control group. However, in contrast to (...) earlier findings, we found that explicit knowledge of the task structure is also good in both the amnesic and the control group. This is inconsistent with a crucial prediction from the multiple-systems account. The results can be explained from a single system account and previously found differences in later categorization performance can be accounted for by a difference in learning rate. (shrink)

In her 1988 paper, “Losing Your Concepts,” Cora Diamond explores the interplay and overlap among different forms of conceptual loss. Diamond’s discussion emphasizes the difficulty of measuring the effect of conceptual loss, owing in part to the difficulty of determining the extent of a concept’s entanglement with other aspects of the life where that concept has its home. Diamond’s remarks are instructive for gathering and assessing Wittgenstein’s scattered remarks on the concept of hope and the questions he raises regarding what (...) it would mean to lack the concept of hope altogether. The problem Wittgenstein’s remarks reveal is the instability between the notion of a life without hope and the putatively different notion of a life without the concept of hope. I argue in the paper that the case of Camus’ The Myth of Sisyphus provides a vivid illustration of this instability. (shrink)

We provide a Hilbert-style axiomatization of the logic of , as well as a two-dimensional semantics with respect to which our logics are sound and complete. Our completeness results are quite general, pertaining to all such actuality logics that extend a normal and canonical modal basis. We also show that our logics have the strong finite model property and permit straightforward first-order extensions.
