Explores the confusion among physicists at the beginning of the 20th century when experimental findings kept not fitting into their mechanical view of the universe, the theoretical speculations and experimental innovations they responded with, and the new science that emerged. The mathematical details are set apart in boxes to allow nontechnical readers to engage the flow of the narrative uninterrupted. Paper edition (unseen), $29.95.

Drawing on the latest work in cognitive neuroscience, a philosopher proposes that delusions are narrative models that accommodate anomalous experiences.

When we are faced with a choice among acts, but are uncertain about the true state of the world, we may be uncertain about the acts’ “choiceworthiness”. Decision theories guide our choice by making normative claims about how we should respond to this uncertainty. If we are unsure which decision theory is correct, however, we may remain unsure of what we ought to do. Given this decision-theoretic uncertainty, meta-theories attempt to resolve the conflicts between our decision theories...but we may be (...) unsure which meta-theory is correct as well. This reasoning can launch a regress of ever-higher-order uncertainty, which may leave one forever uncertain about what one ought to do. There is, fortunately, a class of circumstances under which this regress is not a problem. If one holds a cardinal understanding of subjective choiceworthiness, and accepts certain other criteria, one’s hierarchy of metanormative uncertainty ultimately converges to precise definitions of “subjective choiceworthiness” for any finite set of acts. If one allows the metanormative regress to extend to the transfinite ordinals, the convergence criteria can be weakened further. Finally, the structure of these results applies straightforwardly not just to decision-theoretic uncertainty, but also to other varieties of normative uncertainty, such as moral uncertainty.

Evolutionary Psychology is based on the idea that the mind is a set of special purpose thinking devices or modules whose domain-specific structure is an adaptation to ancestral environments. The modular view of the mind is an uncontroversial description of the periphery of the mind, the input-output sensorimotor and affective subsystems. The novelty of EP is the claim that higher order cognitive processes also exhibit a modular structure. Autism is a primary case study here, interpreted as a developmental failure of (...) a module devoted to social intelligence or Theory of Mind. In this article I reappraise the arguments for innate modularity of TOM and argue that they fail. TOM ability is a consequence of domain general development scaffolded by early, innately specified, sensorimotor abilities. The alleged Modularity of TOM results from interpreting the outcome of developmental failures characteristic of autism at too high a level of cognitive abstraction. (shrink)

The following syllogism is considered: a string is not an expression unless it is tokenable; no one can utter, write, or in anyway token an infinite string; so no infinite string is an expression. The second premise is rejected. But the tokenability of an infinite sentence is not sufficient for it being an infinite expression. A further condition is that no finite sentence expresses that sentence’s truth-conditions. So it is an open question whether English contains infinite expressions.

Engaging variously with the legacy of Paul L. Lehmann, these essays argue for a reorientation in Christian theology that better honours the formative power of ...

Delusions are explanations of anomalous experiences. A theory of delusion requires an explanation of both the anomalous experience _and _the apparently irrational explanation generated by the delusional subject. Hence, we require a model of rational belief formation against which the belief formation of delusional subjects can be evaluated. _Method. _I first describe such a model, distinguishing procedural from pragmatic rationality. Procedural rationality is the use of rules or procedures, deductive or inductive, that produce an inferentially coherent set of propositions. Pragmatic (...) rationality is the use of procedural rationality _in context_. I then apply the distinction to the explanation of the Capgras and the Cotard delusions. I then argue that delusions are failures of pragmatic rationality. I examine the nature of these failures employing the distinction between performance and competence familiar from Chomskian linguistics. _Results. _This approach to the irrationality of delusions reconciles accounts in which the explanation of the anomalous experience exhausts the explanation of delusion, accounts that appeal to further deficits within the reasoning processes of delusional subjects, and accounts that argue that delusions are not beliefs at all. (Respectively, one-stage, two-stage, and expressive accounts.) _Conclusion. _In paradigm cases that concern cognitive neuropsychiatry the irrationality of delusional subjects should be thought of as a performance deficit in pragmatic rationality.

The development of effective means to enhance research integrity by universities requires baseline measures of individual, programmatic, and institutional factors known to contribute to ethical decision making and behavior. In the present study, master’s thesis and Ph.D. students in the fields of biological, health and social sciences at a research extensive university completed a field appropriate measure of research ethical decision making and rated the seriousness of the research issue and importance for implementing the selection response. In addition they were (...) asked to rate their perceptions of the institutional and departmental research climate and to complete a measure of utilitarian and formalistic predisposition. Female students were found to be more ethical in their decision making compared to male students. The research ethical decision measure was found to be related to participants’ ethical predisposition and overall perception of organizational and departmental research climate; however, formalism was the only individual predictor to reach statistical significance and none of the individual subscales of the research climate measure were significantly correlated to ethicality. Participants’ ratings of the seriousness of the issue were correlated with their ratings of the importance of carrying out their selected response but neither was significantly predictive of the ethicality of their responses. The implications of these findings for the development of more effective training programs and environments for graduate students in research ethics and integrity are discussed. (shrink)

Can we succeed in giving consciousness a naturalistic explanation, that is, an explanation in “broadly physical terms”? This is the “problem of consciousness” which, along with other aspects of the mind-body problem, is explored by McGinn in a collection of eight independently written but related, sometimes overlapping papers, all but two previously published. The papers span a decade and divergent approaches. The resulting juxtaposition of two contrasting “resolutions” of the problem by the same author invites their comparison.

Behavioral genetics has as its goal the discovery of genes that play a significant causal role in complex phenotypes that are socially relevant such a parenting, aggression, psychiatric disorders, intelligence, and even race. In this article, I present the stories of the discoveries of three such important phenotypes: maternal nurturing behavior and the c-fosB gene; intelligence and phenylketonuria ; and pair-bonding and monogamy and show that the reality is considerably more complex than often portrayed. These accounts also lay bare some (...) fundamental misconceptions of this field in which genes hold a privileged place and inherently subjective phenomena are mistakenly objectified. (shrink)

Le but de cet article, par l'introduction d'un terme spécifique, transocialisation, est de suggérer un fondement philosophique et théologique unifié pour des interprétations pratico-sociales, d'abord des actions de Jésus de Nazareth à table avec des pécheurs et à la Dernière Cène, puis de la transmutation et de la distribution des éléments du pain et du vin lors de la liturgie eucharistique, et, pour finir, de la grâce objective qui est immédiatement accordée aux communiants et de la grâce d'intention qui doit (...) se manifester dans leur pratique du don de soi.

Nativists about syntactic processing have argued that linguisticprocessing, understood as the implementation of a rule-basedcomputational architecture, is spared in Williams syndrome, (WMS)subjects – and hence that it provides evidence for a geneticallyspecified language module. This argument is bolstered by treatingSpecific Language Impairments (SLI) and WMS as a developmental doubledissociation which identifies a syntax module. Neuroconstructivists haveargued that the cognitive deficits of a developmental disorder cannot beadequately distinguished using the standard gross behavioural tests ofneuropsychology and that the linguistic abilities of the (...) WMS subject canbe equally well explained by a constructivist strategy of neurallearning in the individual, with linguisitic functions implemented in anassociationist architecture. The neuroconstructivist interpretation ofWMS undermines the hypothesis of a double dissociation between SLI andWMS, leaving unresolved the question of nativism about syntax. Theapparent linguistic virtuosity of WMS subjects is an artefact ofenhanced phonological processing, a fact which is easier to demonstratevia the associationist computational model embraced byneuroconstructivism.

The s, p, d and f blocks of the elements, as delimited by Charles Janet in 1928, can be represented as parallel slices of a regular tetrahedron. They also fit neatly on to the surface of a sphere. The reasons for this are discussed and the possible objections examined. An attempt is made to see whether there are philosophical implications of this unexpected geometrical regularity. A new tetrahedral design in transparent plastic is presented.

This book shows how time is a fundamental element in our perception of the arts and proposes an integrated framework within which to explore and appreciate the subtleties and complexities of this essential key to the reading and understanding of meaning in art. The book is a work of ideas, not abstract theory or pure art history. It offers wide-ranging insight into the aesthetics and philosophies of time across different art forms, cultures, and periods. Intended for both arts practitioners and (...) anyone wishing to extend their understanding of the creative process and its underlying principles, the book reveals the interplay of art and time from technical execution and formal invention to the spiritual and intuitive. It opens up fresh possibilities for artists to develop their work in new directions, and for the visitor to engage with artworks including architecture, drawing, sculpture, painting, and photography, in challenging and fulfilling new ways.
