Recent data indicate that under a specific posthypnotic suggestion to circumvent reading, highly suggestible subjects successfully eliminated the Stroop interference effect. The present study examined whether an optical explanation could account for this finding. Using cyclopentolate hydrochloride eye drops to pharmacologically prevent visual accommodation in all subjects, behavioral Stroop data were collected from six highly hypnotizables and six less suggestibles using an optical setup that guaranteed either sharply focused or blurred vision. The highly suggestibles performed the Stroop (...) task when naturally vigilant, under posthypnotic suggestion not to read, and while visually blurred; the less suggestibles ran naturally vigilant, while looking away, and while visually blurred. Although visual accommodation was precluded for all subjects, posthypnotic suggestion effectively eliminated Stroop interference and was comparable to looking away in controls. These data strengthen the view that Stroop interference is neither robust nor inevitable and support the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing.

Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

This paper considers prevailing environmental policy in the United States with the emphasis on liberty, markets, utilizing information, entrepreneurial discovery, and the economic analysis of political decisions. The general discussion is illustrated by the concern over global warming and policies for addressing this concern. The political incentives to confront environmental problems directly with mandates, restrictions, and subsidies ignore the power of liberty and market incentives to solve problems by fostering an impressive network of information transfer, increasing innovation, and expanding prosperity. (...) Indeed, most environmental policies systematically suppress liberty, censor the communication of information, and retard innovation and prosperity, with the result that they provide less environmental quality at greater cost than is possible. While such flawed policies might be justified in cases where pollution problems pose clear, serious, and immediate threats, we argue this is not true of global warming, and the most effective response to concerns over carbon emissions may be limiting the discretionary power of government to take direct action and rely on the indirect effects of liberty and market incentives to move us beyond the petroleum age more quickly and efficiently than will result from the direct action of government.

“Towards a Theory of Taxation” is a proper theme for an Englishman to take when giving a paper in America. After all it was from the absence of such a theory that the United States derived its existence. The Colonists felt strongly that there should be no taxation without representation, and George III was unable to explain to them convincingly why they should contribute to the cost of their defense. Since that time, understanding has not advanced much. In Britain we (...) still maintain the fiction that taxes are a voluntary gift to the Crown, and taxing statutes are given the Royal Assent with the special formula, “La Reine remercie ses bons sujets, accepte leur benevolence, et ainsi le veult” instead of the simple “La Reine le veult,” and in the United States taxes have regularly been levied on residents of the District of Columbia who until recently had no representation in Congress, and by the State of New York on those who worked but did not reside in the State, and so did not have a vote. Taxes are regularly levied, in America as elsewhere, on those who have no say on whether they should be levied or how they should be spent. I am taxed by the Federal Government on my American earnings and by state governments on my American spending, but I should be hard put to it to make out that it was unjust. Florida is wondering whether to follow California in taxing multinational corporations on their world-wide earnings. (shrink)
The thesis of this book is that people enter into social contracts because they are different from one another and have incentives to cooperate. In economic life, people have identical interests—namely, their own se- interests—so they have an incentive to compete. The social worlds that we create, or map, and those that are already mapped for us are increasingly complex, and thus the tracking of rationality is not so straightforward, although it is everywhere evident. In a sense, this book grew (...) out of two questions: Why hasn't the United States had a second revolution? Or is the revolution yet to come? Many have discussed the current crises that confront contemporary society, such as great economic inequalities, poverty, the declining quality of jobs, the growing power of corporate elites, and racial antago nisms. I attempt to understand these problems in terms of the radical restructuring of social life by economic and spatial forces. My specula tive thesis is that social organizations must reinforce social contracts and nurture the opportunities for them to be forged. However, contemporary organizations, particularly economic ones, have internalized the princi ples of economic markets, thereby inducing competition and easing out cooperation. In defining social contracts, I draw from Rousseau and also from Marx and his analysis of use value. One hopes that new organiza tional forms based on principles of democracy and community will evolve. In a diverse, multicultural society, this requires great mutual understanding and cooperation and the recognition of differences. (shrink)
Philosophical hermeneutics provides a model of interreligious dialogue that acknowledges the interpretive variability of truth claims while maintaining their relation to a preinterpretive reality. The dialectic and tensive structure of philosophical hermeneutics directly parallels the tension between the diversity of belief and the ultimacy of the sacred. By placing philosophers like Gadamer, Ricoeur, Peirce, and Whitehead in conversation, J. R. Hustwit describes religious truth claims as coconstituted by the planes of linguistic convention and uninterpreted otherness. Only when we recognize that (...) religious claims emerge from a dalliance back and forth across the limits of the understanding can we appreciate the engagement between religions. In terms of dialogue, this approach treats religious truth claims as tentative hypotheses, but hypotheses that are frequently commensurable and rationally contestable. Interreligious dialogue goes beyond facilitating bonhomie or negotiating tolerance; dialogue can and should be a disciplined space for rationally adjudicating claims about what lies beyond the limits of human understanding.

J. R. and Philip Milton present the first critical edition of John Locke's Essay concerning Toleration, based on all extant manuscripts, and a number of other writings on law and politics composed between 1667 and 1683. Although Locke never published any of these works himself they are of very great interest for students of his intellectual development because they are markedly different from the early works he wrote while at Oxford and show him working out ideas that were to appear (...) in his mature political writings, the Two Treatises of Government and the Epistola de Tolerantia. With authoritative contextual guidance from the editors, this will be an invaluable resource for all historians of early modern philosophy, of legal, political, and religious thought, and of 17th century Britain.

This paper outlines Lewis’s favoured foundational account of linguistic representation, and outlines and briefly evaluates variations and modifications. Section 1 gives an opinionated exegesis of Lewis’ work on the foundations of reference—his interpretationism. I look at the way that the metaphysical distinction between natural and non-natural properties came to play a central role in his thinking about language. Lewis’s own deployment of this notion has implausible commitments, so in section 2 I consider variations and alternatives. Section 3 briefly considers a (...) buck-passing strategy involving fine-grained linguistic conventions. (shrink)
Context: The past few years have presented us with a growing amount of theoretical research (yet that is often based on neuroscientific developments) in the field of enactive music cognition. Problem: Current cognitivist and embodied approaches to music cognition suffer, in our opinion, from a too firm commitment to the explanatory role of mental representations in musical experience. This particular problem can be solved by adopting an enactive approach to music cognition. Method: We present and compare cognitivist, embodied and enactive (...) approaches to music cognition and review the current research in enactive music cognition. Results: We find that, in general, the enactive approaches to human musicality are capable of explaining the basic relationship between a musical subject and a musical object according to a pre-conceptual and pre-linguistic form of understanding related to bodily motor expertise. This explanation does not rely on on sophisticated forms of representation. Implications: Proponents of enactive music cognition should, in our opinion, focus on providing a consistent explanation of the most basic level of musical understanding. Constructivist content: We hope to invite the constructivist community to engage with the discussions on the intersection between music and enactivism. (shrink)
That space and time should be integrated into a single entity, spacetime, is the great insight of Einstein's special theory of relativity, and leads us to regard spacetime as a fundamental context in which to make sense of the world around us. But it is not the only one. Causality is equally important and at least as far as the special theory goes, it cannot be subsumed under a fundamentally geometrical form of explanation. In fact, the agent of propagation of (...) causal influence is electromagnetic radiation. In this examination, the authors find support for a rationalist approach to physics, never neglecting experimentation, but rejecting a simple empiricist or positivist view of science. (shrink)
