L’article prend en considération la façon dont différents auteurs rassemblés sous l’étiquette générale de « présocratiques » commençaient leurs discours. Dans le contexte d’une transmission essentiellement orale tel que celui de la culture de la Grèce archaïque, l’incipit prend une importance fondamentale, dans la mesure où il pose les bases de la communication, définit le type de message que l’auteur veut transmettre et indique dans quelle voie il s’engage. Il donne donc des indications non seulement sur le type de texte, (...) mais aussi sur le genre de public auquel ce texte était adressé. S’il s’agit d’un public restreint et choisi, l’incipit est généralement élitiste, obscur, et fait référence à un code auquel il est difficile d’accéder ou, comme dans le cas de l’écrit d’Alcméon, mise sur la difficulté d’une entreprise que les disciples doivent surmonter à l’aide de l’enseignement du maître. Si le texte est destiné à un public plus large d’amateurs cultivés, il mise sur des phrases ronflantes qui suscitent des visions grandioses et des émotions et placent l’orateur dans une position dominante vis-à-vis de l’auditoire. Ici on prend en considération en particulier les incipit de quatre auteurs assez différents les uns des autres, de la fin du vie au dernier tiers du ve siècle av. J.‑C. : Héraclite, Alcméon, Anaxagore et Diogène d’Apollonie. En recourant à l’analyse linguistique et en les confrontant avec d’autres textes de même époque, on cherche à définir la particularité de chaque texte en relation avec le message qu’il véhicule et avec ses destinataires. Les résultats de cette analyse invitent à reconsidérer la méthode à employer pour aborder les fragments des auteurs dits présocratiques et à se libérer du modèle herméneutique « anthologique » d’Aristote qui vise à rechercher un « système » philosophique et néglige le rythme prosodique, l’harmonie de la langue, le caractère persuasif des textes et leur contexte culturel.

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

Philosophers agree that scientific explanations aim to produce understanding, and that good ones succeed in this aim. But few seriously consider what understanding is, or what the cues are when we have it. If it is a psychological state or process, describing its specific nature is the job of psychological theorizing. This article examines the role of understanding in scientific explanation. It warns that the seductive, phenomenological sense of understanding is often, but mistakenly, viewed as a cue of genuine understanding. (...) The article closes with a discussion of several new paths of research that tie the psychology of scientific explanation to cognate notions of learning, testimony, and understanding. (shrink)

Scientific realists contend that theory-conjunction presents a problem for empiricist conceptions of scientific knowledge and practice. Van Fraassen (1980) has offered a competing account of theory-conjunction which I argue fails to capture the mercenary character of epistemic dependence in science. Representative cases of theory-conjunction developed in the present paper show that mercenary reliance implies a "principle of epistemic symmetry" which only a realist can consistently accommodate. Finally, because the practice in question involves the conjunction of theories, a version of realism (...) more robust than the "entity realism" of Cartwright (1983, 1989) and Hacking (1983) is required to explain the success of theory-conjunction.

The use of null hypothesis significance testing (NHST) in psychology has been under sustained attack, despite its reliable use in the notably successful, so-called "hard" areas of psychology, such as perception and cognition. I argue that, in contrast to merely methodological analyses of hypothesis testing (in terms of "test severity," or other confirmation-theoretic notions), only a patently metaphysical position can adequately capture the uneven but undeniable successes of theories in "hard psychology." I contend that Measured Realism satisfies this description, and (...) characterizes the role of NHST in hard psychology. (shrink)

Editors’ note: These four interrelated discussions of the role of the cerebellum in coordinating emotional and higher cognitive functions developed out of a workshop presented by the four authors for the 2000 Conference of the Cognitive Science Society at the University of Pennsylvania. The four interrelated discussions explore the implications of the recent explosion of cerebellum research suggesting an expanded cerebellar role in higher cognitive functions as well as in the coordination of emotional functions with learning, logical thinking, perceptual consciousness, (...) and action planning.

We show that if the weak compactness of a cardinal is made indestructible by means of any preparatory forcing of a certain general type, including any forcing naively resembling the Laver preparation, then the cardinal was originally supercompact. We then apply this theorem to show that the hypothesis of supercompactness is necessary for certain proof schemata.

It is widely agreed that a new conception of history was developed in the early nineteenth century: the past came to be seen in a new light, as did the way of studying the past. This article discusses the nature of this collective revision, focusing on one of its first and most important manifestations: Ranke's 1824 Geschichten der romanischen und germanischen Völker. It argues that, in Ranke's case, the driving force of the revision was religious, and that, subsequently, an understanding (...) of the nature of Ranke's religious attitude is vital to any interpretation of his historical revision. Being aesthetic-experiential rather than conceptual or "positive," this religious element is reflected throughout Ranke's enterprise, in source criticism and in historical representation no less than in the conception of cause and effect in the historical process. These three levels or aspects of the historical enterprise correspond to the experience of the past, and are connected by the essence of the experience: visual perception. The highly individual character of the enterprise, its foundation in sentiments and experiences of little persuasive force that only with difficulty can be brought into language at all, explains the paradoxical nature of the Rankean heritage. On the one hand, Ranke had a great and lasting impact; on the other hand, his approach was never re-utilized as a whole, only in its constituent parts—which, when not in the relationship Ranke had envisioned, took on a new and different character. This also suggests the difference between Ranke's revision and a new paradigm: whereas the latter is an exemplary solution providing binding regulations, the former is unrepeatable. (shrink)

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)
