Autism is a group of complex neurodevelopmental disorders characterized by impaired social interaction and restricted/repetitive behavior. We performed a large-scale retrospective analysis of 1,996 clinical neurological structural magnetic resonance imaging (MRI) examinations of 781 autistic and 988 control subjects (aged 0 to 32 years), and extracted regionally distributed cortical thickness measurements, including average measurements as well as standard deviations which supports the assessment of intra-regional cortical thickness variability. The youngest autistic participants (< 2.5 years) were diagnosed after imaging and were (...) identified retrospectively. The largest effect sizes and the most common findings not previously published in the scientific literature involve abnormal intra-regional variability in cortical thickness affecting many (but not all) regions of the autistic brain, suggesting irregular gray matter development in autism that can be detected with MRI. Atypical developmental patterns have been detected as early as 0 years old in individuals who would later be diagnosed with autism. (shrink)

This chapter provides broad coverage of the notion of logical consequence, exploring its modal, semantic, and epistemic aspects. It develops the contrast between proof-theoretic notion of consequence, in terms of deduction, and a model-theoretic approach, in terms of truth-conditions. The main purpose is to relate the formal, technical work in logic to the philosophical concepts that underlie reasoning.

This Oxford Handbook covers the current state of the art in the philosophy of maths and logic in a comprehensive and accessible manner, giving the reader an overview of the major problems, positions, and battle lines. The 26 newly-commissioned chapters are by established experts in the field and contain both exposition and criticism as well as substantial development of their own positions. Select major positions are represented by two chapters - one supportive and one critical. The book includes a comprehensive (...) bibliography. (shrink)

This paper critically evaluates the effect of introducing markets into the institutional system of education and promotes the claim of a learning democracy to underpin a richer conception for developing the powers and capacities of all citizens.

Coregulation refers to the process by which relationship partners form a dyadic emotional system involving an oscillating pattern of affective arousal and dampening that dynamically maintains an optimal emotional state. Coregulation may represent an important form of interpersonal emotion regulation, but confusion exists in the literature due to a lack of precision in the usage of the term. We propose an operational definition for coregulation as a bidirectional linkage of oscillating emotional channels between partners, which contributes to emotional stability for (...) both partners. We propose several distinctions and raise unanswered questions that will need to be addressed in order to understand the relevance of coregulation for well-being in adulthood. (shrink)

The purpose of this article is to explore the extent to which mathematics is subject to open texture and the extent to which mathematics resists open texture. The resistance is tied to the importance of proof and, in particular, rigor, in mathematics.

Dmitri Mendeleev’s detailed prediction in 1871 of the properties of three as yet unknown elements earned him enormous prestige. Eleven other predictions, thrown off without elaboration, were less uniformly successful, thanks mainly his unbending adherence to the structure of his table and his failure to account for the lanthanides. At the end of his life he returned to his table without making the required changes, and added a theoretical discussion of elements lighter than hydrogen. The overall balance of success and (...) failure is nevertheless in his favour. There may now be a similar failure to understand the ultra-heavy elements because of adherence to the pattern of chemical groups. (shrink)

In this short note, we discuss several aspectsof dimensions and the related constructof factors. We concentrate on those aspectsthat are relevant to articles in this specialissue, especially those dealing with the analysisof the wild animal cases discussed inBerman and Hafner's 1993 ICAIL article. We reviewthe basic ideas about dimensions,as used in HYPO, and point out differences withfactors, as used in subsequent systemslike CATO. Our goal is to correct certainmisconceptions that have arisen over the years.

This book discusses five philosophers and writers, Hume, Kierkegaar, Camus, Simone Weil and Dostoevsky, who represents different strands of our cultural inheritance which are all theologically and religiously alive today. What they have in common is willingness to explore the borderlands between belief and unbelief and to review their own position in the light of what those coming from the opposite direction may have to teach them. What they each reject is the sort of caricature which assumes that belief an (...) unbelief and to review their own position in the light of what those coming from the opposite direction may have to teach them. What they each reject is the sort of caricature which assumes that belief and unbelief are two homogeneous wholes which have nothing to say to each other and no ground for common discussion other that that of agnosticism. Equally, however, they disdain the implications that the only possibility of dialogue is a marshmallow middle ground where the only rule is that you avoid saying what you really think. Theologians and believers have often stood back from exploration on this middle ground. Encounters with secular philosophies or systems of belief are risky and dangerous. On the other hand, a theology which avoids such encounters is a much impoverished theology. Professor Sutherland's discussion considers the nature and extent of the risk, and the title of his book indicates where the believers who live close to the boundaries often share more with neighbourly unbelievers than they do with fellow believers who view the pastures of unbelief as far distant and dangerou lands from which they will for ever remain separated.

It was, I believe, Thomas Arnold who wrote: ‘Educate men without religion and all you make of them is clever devils’. Thus the Headmaster of one famous school summarized pithily the view of the relationship between religion and ethics which informed educational theory and practice in this country for at least a further century. There is a confusion of two different assumptions usually to be found in this context. The first is that religious belief can provide an intellectual foundation for (...) moral belief; the second is that the effect of religious teaching is to improve behaviour according to the norms of some particular set of moral beliefs.

In the Politics of Black Joy, Lindsey Stewart develops Hurston's contributions to political theory and philosophy of race by introducing the politics of joy as a refusal of neoabolitionism, a political tradition that reduces southern Black life to tragedy or social death.

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the literature. (...) We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)

The answers to the questions in the title depend on the kind of pluralism one is talking about. We will focus here on our own views. The purpose of this article is to trace out some possible connections between these kinds of pluralism. We show how each of them might bear on the other, depending on how certain open questions are resolved.

Saul Kripke once noted that there is a tight connection between computation and de re knowledge of whatever the computation acts upon. For example, the Euclidean algorithm can produce knowledge of which number is the greatest common divisor of two numbers. Arguably, algorithms operate directly on syntactic items, such as strings, and on numbers and the like only via how the numbers are represented. So we broach matters of notation. The purpose of this article is to explore the relationship between (...) the notations acceptable for computation, the usual idealizations involved in theories of computability, flowing from Alan Turing’s monumental work, and de re propositional attitudes toward numbers and other mathematical objects.

This paper addresses the ethical challenges raised by the use of lethal autonomous weapons systems. Using aspects of the philosophy of Martin Heidegger, the paper demonstrates that lethal autonomous weapons systems create ethical problems because of the lack of moral agency in an autonomous system, and the inauthentic nature of the deaths caused by such a system. The paper considers potential solutions for these issues before arguing that from a Heideggerian standpoint they cannot be overcome, and thus the development and (...) use of lethal autonomous weapons systems should be resisted and prohibited.

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 paper investigates Locke’s views about materialism, by looking at the discussion in Essay IV.x. There Locke---after giving a cosmological argument for the existence of God---argues that God could not be material, and that matter alone could never produce thought. In discussing the chapter, I pay particular attention to some comparisons between Locke’s position and those of two other seventeenth-century philosophers, René Descartes and Ralph Cudworth. -/- Making use of those comparisons, I argue for two main claims. The first is (...) that the important argument of Essay IV.x.10 is fundamentally an argument about the causation of perfections. Indeed, Locke gives multiple such arguments in the chapter. My second main claim is that my proposed reading of IV.x is not merely consistent with what Locke says elsewhere about superaddition, but also provides reasons to favor a particular understanding of what superaddition is.

The oeuvre of Hegel, like that of many thinkers of the post-Kantian tradition in European philosophy, has been subject to a number of misreadings and misrepresentations by both specialists and nonspecialists alike that have until fairly recently rendered Hegel’s reception in the Anglo-American philosophical world extremely problematic. These often willful misrepresentations, variously referred to by scholars as the Hegel myths or legends, have given rise to a number of prejudices against Hegel’s philosophy primarily, although by no means exclusively, in the (...) English-speaking world. Among the caricatures that have enjoyed the widest currency are the following: that Hegel denied the law of contradiction; that his dialectical method of argumentation took the form of the thesis-antithesis-synthesis triad; that he saw the end of history in his own philosophical system; that he tried to prove a priori the number of planets; that he was a reactionary apologist for the Prussian state, or worse, a protofascist; finally, that he was a kind of pre-Kantian metaphysician or “cosmic rationalist” who believed like Schelling and some of the Romantics in a metaphysical world soul.

SummaryWithin thirty years from 1870, English physiology was transformed from a subsidiary branch of anatomy to an experimental school of international reputation. An inevitable consequence of this metamorphosis was disclosure of the intrinsic nature of the new discipline, in particular by Burdon Sanderson's Handbook for the Physiological Laboratory (1873). By transmitting Continental methods to England, the Handbook gave direction to its awakening science, and at the same time represented a provocative target for attacks by the antivivisectionists. In uncertain defence of (...) their methods, the beleaguered physiologists exposed awkward inconsistencies of word and deed that reflected fundamental (if not unique) problems of internal ethics and of public accountability. Though to many the discipline remained technically brutal and aesthetically coarse, the necessary suffering of the intuitionists' nightmares could soon, by the growing and undeniable impact of therapeutic medicine, be presented as a justifiable price for the utilitarian dream.

Most of us have probably heard Samuel Johnson's witticism about the reported proposal of an acquaintance to enter into a second marriage—‘the triumph of hope over experience’. Whatever that tells us about his friend's previous marriage, it tells us quite a bit about the popular understanding of hope. A similiar point was implied by J. B. Priestley when he referred to whisky distillers marketing faith and hope at twelve shillings and sixpence per bottle, and not for the first time G. (...) K. Chesterton got it superficially wrong in defining hope as ‘the power of being cheerful in circumstances which we know to be desperate’. (shrink)

The first attempt to represent the Periodic system graphically was the Telluric Helix presented in 1862 by Alexandre-Emile Béguyer de Chancourtois, in which the sequence of elements was wound round a cylinder. This has hardly been attempted since, because the intervals between periodic returns vary in length from 2 to 32 elements, but Charles Janet presented a model wound round four nested cylinders. The rows in Janet’s table are defined by a constant sum of the first two quantum numbers, n (...) and l, so that they end with the s-block, headed by hydrogen and helium. By combining Janet’s table, Edward Mazurs’ version, in which each row represents an electron shell and Valery Tsimmerman’s use of a half square for each element, I have produced a representation that can be printed out and wound round to make a cylinder with manageable dimensions. In the unwound version, I have placed the s-block in the middle, to emphasise its pivotal nature, since it both ends each row and contributes electrons to the valence of elements in the next row; it thus does not necessarily belong either on the left or the right side of a table. The downward arrows that link subshells within each series graphically illustrate the Janet Effect. To acknowledge my debt to Chancourtois, Janet, Mazurs and Tsimmerman, I call my design the ‘Telluric Remix’. (shrink)

A familiar adage in the philosophy of science is that general hypotheses are better supported by varied evidence than by uniform evidence. Several studies suggest that young children do not respect this principle, and thus suffer from a defect in their inductive methodology. We argue that the diversity principle does not have the normative status that psychologists attribute to it, and should be replaced by a simple rule of probability. We then report experiments designed to detect conformity to the latter (...) rule in children's inductive judgment. The results suggest that young children in both the United States and Taiwan are sensitive to the constraints imposed by the rule on judgments of probability and evidential strength. We conclude with a suggested reinterpretation of the thesis that children's inductive methodology qualifies them as “little scientists.”. (shrink)
