The Poetic Structure of the World is a major reconsideration of a crucial turningpoint in Western thought and culture: the heliocentric revolution of Copernicus and Kepler. FernandHallyn treats the work of these two figures not simply in terms of the history of science orastronomy, but as events embedded in a wider field of images, symbols, texts, and practices. Thesenew representations of the universe, he insists, cannot be explained by recourse to explanations of"genius" or "intuition."Instead, Hallyn investigates the problem of (...) how new scientific hypothesesare actually formed and the complex way in which certain facts and not others are selected tosupport a particular theory. He contends that the scientific imagination is not fundamentallydifferent from a mythic or poetic imagination and that the work of Copernicus and Kepler must beexamined on the level of rhetorical structure. Hallyn shows the sun-centered universe to beinseparable from the aesthetic, epistemological, theological, and social imperatives of bothneoplatonism and mannerism in the sixteenth centuryFernand Hallyn is a Professor in the Departmentof French Literature at the University of Ghent.

Cet ouvrage se veut une lecture rhétorique de quelques problèmes-clés ayant marqué la période qui s'étend des débuts de la révolution scientifique du XVIIe siècle jusqu'au moment où, au XIXe, une autre se prépare. Une telle sorte d'analyse se fonde sur le fait qu'avant d'intervenir dans les efforts de persuasion, certains schèmes " poétiques " sont déjà présents et actifs dans la formation et l'acceptation de toute représentation nouvelle. C'est pourquoi la " rhétorique profonde " que nous propose ici (...) class='Hi'>Fernand Hallyn ne se contente nullement d'éclairer les procédés de la science qui interviennent dans la communication de positions, de démarches ou de résultats, mais vise d'abord à étudier ses formes d'invention et de découverte. Saisir la démarche scientifique en train de se faire comme un cas particulier de la problématique générale de la créativité - bref explorer plus avant la voie ouverte dans La Structure poétique du mande - tel est donc l'enjeu de ce volume.

Gemma Frisius (1508–1555), who worked at the university of Louvain, heard about the Copernican system already around 1530 and afterwards was a careful reader of the Narratio prima and the De Revolutionibus. The article argues that his posthumous preface to the Ephemerides (1556) by his pupil Stadius expresses his ultimate opinion on the system of the world. Moreover, it is also the only text where he tackles the epistemological problems of the question. A careful analysis of this preface shows that (...) at the end of his life, on the ground of observations as well as philosophical demands, he admitted at least the first two movements ascribed to the earth by Copernicus.

In a famous study of expert problem solving, de Groot (1946/1978) examined how chess players found the best move. He reported that there was little difference in the way that the best players (Grand Masters) and very good players (Candidate Masters) searched the board. Although this result has been regularly cited in studies of expertise, it is frequently misquoted. It is often claimed that de Groot found no difference in the way that experts and novices investigate a problem. Comparison of (...) expert and novice chess players on de Groot's problem shows that there are clear differences in their search patterns. We discuss the troublesome theoretical and practical consequences of incorrectly reporting de Groot's findings. (shrink)

Advances in artificial intelligence (AI) raise important questions about whether people view moral evaluations by AI systems similarly to human-generated moral evaluations. We conducted a modified Moral Turing Test (m-MTT), inspired by Allen et al. (Exp Theor Artif Intell 352:24–28, 2004) proposal, by asking people to distinguish real human moral evaluations from those made by a popular advanced AI language model: GPT-4. A representative sample of 299 U.S. adults first rated the quality of moral evaluations when blinded to their source. (...) Remarkably, they rated the AI’s moral reasoning as superior in quality to humans’ along almost all dimensions, including virtuousness, intelligence, and trustworthiness, consistent with passing what Allen and colleagues call the comparative MTT. Next, when tasked with identifying the source of each evaluation (human or computer), people performed significantly above chance levels. Although the AI did not pass this test, this was not because of its inferior moral reasoning but, potentially, its perceived superiority, among other possible explanations. The emergence of language models capable of producing moral responses perceived as superior in quality to humans’ raises concerns that people may uncritically accept potentially harmful moral guidance from AI. This possibility highlights the need for safeguards around generative language models in matters of morality. (shrink)

For many years, the game of chess has provided an invaluable task environment for research on cognition, in particular on the differences between novices and experts and the learning that removes these differences, and upon the structure of human memory and its paramaters. The template theory presented by Gobet and Simon based on the EPAM theory offers precise predictions on cognitive processes during the presentation and recall of chess positions. This article describes the behavior of CHREST, a computer implementation of (...) the template theory, in a memory task when the presentation time is varied from one second to sixty, on the recall of game and random positions, and compares the model to human data. Strong players are better than weak players in both types of positions, especially with long presentation times, but even after brief presentations. CHREST predicts the data, both qualitatively and quantitatively. Strong players' superiority with random positions is explained by the large number of chunks they hold in LTM. Their excellent recall with short presentation times is explained by templates, a special class of chunks. CHREST is compared to other theories of chess skill, which either cannot account for the superiority of Masters in random positions or predict too strong a performance of Masters in such positions.

The content of a mental act- a pivotal element of a theory of intentionality- has a threefold meaning: as a logical concept, is the ideal signification, as a psychological concept, is the core of a noema (i.e., the instantiation of an ideal and as an ontological concept, is the object (real or unreal) intented by the nucleus. We can make a parallel between this Husserlian threefold distinction and the Fregean sense/”reference” distinction, reducing it to the sense/object distinction. This paralleism is (...) not to force the Husserl’s thought to Frege’s, but, on the contrary, to show the structure of the triple meaning of content: Husserl mtroduces the difference between ideal signification and instantiated signification, so the pure and Simple signification and the noematic sense are species of the genus sense. Husserl’s theory of intentionality and his philosophy of language does not go Frege, but beyond. The recognition of that allows us to see the error of Føesdal’s mterpretation, as while as those of Sartre and Gurwitsch. The Fregean sense/”reference” distinction is subsumed by the Husserlian conceptual trio ideal signification/noematic sense/object. This triad of concepts houses not only a semantic theory (as Frege’s pair), but also a theory of a theory of perception. Husserl integrates its semantics in a theory of of consciousness that overcomes the intentio doctrines ofBrentano, Twardowsk1 and the medievals. (shrink)

Understanding how look-ahead search and pattern recognition interact is one of the important research questions in the study of expert problem solving. This paper examines the implications of the template theory Gobet & Simon, 1996a , a recent theory of expert memory, on the theory of problem solving in chess. Templates are chunks Chase & Simon, 1973 that have evolved into more complex data structures and that possess slots allowing values to be encoded rapidly. Templates may facilitate search in three (...) ways: a by allowing information to be stored into LTM rapidly; b by allowing a search in the template space in addition to a search in the move space; and c by compensating loss in the minds eye due to interference and decay. A computer model implementing the main ideas of the theory is presented, and simulations of its search behaviour are discussed. The template theory accounts for the slight skill difference in average depth of search found in chess players, as well as for other empirical data. (shrink)

La vie et les oeuvres de J. H. Newman ont suscité de nombreux et importants travaux. L'étude de l'homme lui-même a servi de thème à plusieurs ouvrages ; on a cherché à discerner dans son tempérament la raison de l'originalité de son œuvre ou de l'étendue de son influence ; ailleurs on nous a fait connaitre l'historien, le philosophe, le théologien, mais de tous ces Newman divers, l'éducateur est resté le plus ignoré. Cette constatation fut le point de départ de (...) la présente étude. Or l'éducation, cette activité privilégiée, a si bien été le centre même de la vie de Newman, qu'à elle nous devons non seulement un de ses chefs-d'œuvre les plus achevés, (malheureusement trop peu connu de ceux qui se réclament du Newman du Développement ou de l'Assentiment, voire de celui de l'Apologia), mais presque toutes ses œuvres. Il n'a que bien rarement, peut-être jamais, écrit pour écrire ; il a écrit pour enseigner, et à son âme d'éducateur est dû le caractère particulier de son oeuvre. (shrink)
