1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

Is the United States "the land of equal opportunity" or is the playing field tilted in favor of those whose parents are wealthy, well educated, and white? If family background is important in getting ahead, why? And if the processes that transmit economic status from parent to child are unfair, could public policy address the problem? Unequal Chances provides new answers to these questions by leading economists, sociologists, biologists, behavioral geneticists, and philosophers.New estimates show that intergenerational inequality in the United (...) States is far greater than was previously thought. Moreover, while the inheritance of wealth and the better schooling typically enjoyed by the children of the well-to-do contribute to this process, these two standard explanations fail to explain the extent of intergenerational status transmission. The genetic inheritance of IQ is even less important. Instead, parent-offspring similarities in personality and behavior may play an important role. Race contributes to the process, and the intergenerational mobility patterns of African Americans and European Americans differ substantially.Following the editors' introduction are chapters by Greg Duncan, Ariel Kalil, Susan E.

ABSTRACT The Scottish judge and ‘eccentric’ philosopher James Burnett, Lord Monboddo’s (1714–1799) significance within Enlightenment thought is usually seen as stemming from his Origin and Progress of Language (6 vols., 1773–1792). The OPL was a major contribution to the Enlightenment’s debate over the philosophy of language, and established Monboddo’s reputation as an innovative and influential, yet controversial and credulous proto-anthropologist. In the following I explore Monboddo’s Egyptomania and the role it plays in his account of the origins and development of (...) religion within his larger ‘History of Man’. Monboddo’s idiosyncratic and untimely fusion of conjectural history, Buffon-inspired natural history, Christian theology, Platonic and Aristotelian philosophy and credulous interest in Egyptology, especially in Antient Metaphysics (6 vols., 1779–1799), make him extremely difficult to place within the Scottish Enlightenment. I want to bring Monboddo back into our conversation about the Scottish Enlightenment, shed light in the process on his highly idiosyncratic combination of enlightened and unenlightened thought and, using Monboddo’s example, emphasize some interesting if unexpected aspects of the Scottish Enlightenment’s application of the ‘science of human nature’ to the study of religion. For Monboddo, human civilization and religious knowledge owes their existence to Egyptian daemon-kings. (shrink)

We define the term \a set T of sentential-logical formulae grounds a sentential-logical formula A from a syntactic point of view\ in such a way that A is a syntactic sentential-logical consequence of T, and specific additional syntactic requirements regarding T and A are fulfilled. These additional requirements are developed strictly within the syntactics of sentential-logical languages, the three most important being new, namely: to be atomically minimal, to be minimal in degree, and not to be conjunction-like. Our approach is (...) independent of any specific sentential-logical calculus. (shrink)

Peut-être que jusqu'ici dans les recherches philosophiques sur la nature du temps on a attribué trop peu d'attention à la distinction entre « temps » comme catégorie mathématique d'une part, et « temps » comme il est réalisé dans des processus et des périodes d'autre part. Quand on essaie de combler ce vide, on éprouve le besoin d'impliquer dans ses considérations l'apparition fréquente de « nouveauté » et de « commencement ». C'est pourquoi on examine dans la première partie de (...) cet article comment nous nous formons une notion mathématique du temps. Il apparaît que cela se fait en idéalisant la perception des périodes. On s'imagine que l'unité du temps une fois choisie peut être reproduite exactement, et même jusqu'à l'inñni. En outre on s'imagine que chaque période peut être divisée en des intervalles arbitrairement petits. Un instant est pensé comme une limite nette entre le temps qui précède et le temps qui suit ; ici la séparation entre les deux parties du temps est posée comme absolue contre arrière-plan d'un temps dont justement la cohérence est posée comme absolue. C'est ainsi que naît la catégorie du temps comme une possibilité homogène, toujours égale à elle-même pour indiquer des instants indivisibles et pour délimiter des périodes, à savoir une possibilité qui s'étend sans limites des deux côtés de l'instant actuel, aussi bien vers l'avenir que vers le passé. Quand on indique un instant, deux notions contradictoires sont posées en même temps, à savoir une séparation absolue et une cohérence absolue. Dans la physique ce schéma mathématique s'avère extrêmement utile. Pourtant il s'agit de se rendre toujours compte de l'applicabilité défectueuse de ce schéma, de sorte qu'on fasse attention aux complications qui exigent un complément et une correction de la théorie. Quand on applique le même schéma aussi aux processus vitaux et aux événements psychiques, alors l'incohérence entre le schéma mathématique et la succession réelle des périodes se trouve encore plus grande. Dans la deuxième partie on analyse le « commencement ». De la manière la plus originelle un commencement se présente devant nous, quand nous essayons d'avoir une vue d'ensemble de notre propre vie, comme elle se trouve dans notre mémoire. Dans le passé nous rencontrons alors une frontière que nous ne pouvons pas marquer cependant nettement sur une échelle mathématique. Ainsi en analysant chaque commencement on doit distinguer de nouveau soigneusement le commencement dans le domaine mathématique de celui dans l'ordre réel. Le caractère abrupt qui est propre à un commencement « mathématique » se trouve absent dans un commencement « réel ». Dans la troisième partie il est démontré que le temps et le commencement sont inséparablement liés l'un à l'autre. Le temps réel apparaît partout dans des périodes ayant un commencement et ainsi dans un ensemble compliqué de commencement et de permanence. Toutes les totalités dans la nature vivante et dans la nature inanimée, les individus ainsi que les espèces, ont été neuves une fois. Avant ce commencement multiple notre univers a été neuf. Cependant, alors il appert que cette mesure perd son utilité. Lorsque l'univers était encore en gestation, notre temps, lui aussi, avec sa mesure était en formation. C'est pourquoi une localisation exacte du commencement de l'univers sur l'échelle du temps n'est pas seulement impossible, mais même absurde. Cependant, si un commencement ne peut jamais être déñni de façon mathématique, il est pourtant défini de sa manière particulière dans le temps, c'est à dire par une définition qui essentiellement contient une certaine imprécision. Quant au commencement de l'univers les sciences physiques conduisent par des chemins différents à un même résultat, et font conclure à un âge de l'univers de quatre milliards et demi d'années environ. Finalement une question concernant la notion de création se présente. La tradition connaît en effet une notion de création dans un sens très stricte, distinguée des notions de « conservatio » et de « concursus ». On a l'habitude de lier le fait de la création à un seul ou à quelques instants. Mais nous croyons pouvoir démontrer que dans la dépendance que les créatures ont a l'égard du Créateur, il y a toujours aussi un aspect d' « être créé » dans le sens cité plus haut, un aspect qui se met d'autant plus au premier rang qu'il y a plus de nouveauté et de discontinuité vis à vis du passé.

This short, suggestive essay was the 1972 Aquinas Lecture at Marquette. It contains an outline of Findlay’s critique of "mechanistic neuralism," i.e., belief in "invariant, isolable factors and rigorous laws governing their interaction." In a manner reminiscent of Bergson, he sees this view as the product of specifically intellectual activity which naturally produces a "world of remote objects, all fully interpreted, which stand over against our subjectivity...." Speculative and experimental neurology thus present a view of mind in which the self (...) is identified with the cerebrum. "The cerebrum... becomes the true man... to whom we attribute all our highest preceptive, cogitative, emotional and practical feats". Findlay attacks no particular version of this view. His main concern is to argue against the tendency in thought. He holds that the difficulties faced by a through-going cerebralism are purely logical, and he sketches a number of arguments designed to expose some of the problems involved in reductionist accounts of perception, thought, and action. What makes the essay particularly interesting is the way in which it incorporates scattered but important insights of Wittgenstein, Husserl, and Hegel which bear significantly on any treatment of the mind-brain problem. What is frustrating is the pervasive generality of Findlay’s characterization of "cerebralism." No cerebralist is identified, and no recent defense of the position is discussed or referred to in detail. Perhaps this is both unavoidable and appropriate in a public lecture. But it may leave the reader wondering how Findlay’s critical points apply to recent important discussions of the problem.—J. W. (shrink)

An anthology of essays by Aristotle, Mill, Carroll, Dewey, Russell, Veatch and Ryle, with a brief background statement on each author. Most of the essays are concerned with the relationship of logic to philosophy.--R. J. W.

A readable new translation of commentaries of interest to Biblical exegetes as well as Calvin scholars. Calvin's own doctrine is often more clearly stated here than in the Institutes, and in spite of his polemical situation, much of the commentary is fresh and interesting.—R. J. W.

A good translation of, and selection from, the writings of Sextus. The editor has provided a helpful and entertaining "polemical introduction," in which he argues that Sextus belongs in the tradition which includes Hume and Wittgenstein. Extensive notes further relate the ideas in the text to those of other philosophers.—R. J. W.

Those who know only Anselm the theologian would do well to spend some time with this extremely thorough study of his most famous logical treatise. The author provides a synopsis, a new edition of the text, a new translation, an informal exposition, and a formal one using the logic of Lesniewski. His thesis is that the De Grammatico is a careful and subtle examination of the theory of paronymy, or, in modern terms, the problem of sense and reference. Anselm's work (...) is both placed in its historical context and related to contemporary issues in logic. One might hope that in a revised edition the text and translation would be printed in parallel, rather than in sequence.—R. J. W. (shrink)

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We review (...) the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

I wish to thank Klaus Kühnle who streamlined in [8] several of my definitions and proofs concerning the subject matter of this paper. Some ideas and results arose from discussions with Klaus Leeb. Jan Johannsen discovered some mistakes in an earlier version.
