Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

The posterior parietal cortex (PPC) is the most likely site where egocentric spatial relationships are represented in the brain. PPC cells receive visual, auditory, somaesthetic, and vestibular sensory inputs; oculomotor, head, limb, and body motor signals; and strong motivational projections from the limbic system. Their discharge increases not only when an animal moves towards a sensory target, but also when it directs its attention to it. PPC lesions have the opposite effect: sensory inattention and neglect. The PPC does not seem (...) to contain a “map” of the location of objects in space but a distributed neural network for transforming one set of sensory vectors into other sensory reference frames or into various motor coordinate systems. Which set of transformation rules is used probably depends on attention, which selectively enhances the synapses needed for making a particular sensory comparison or aiming a particular movement.

Filosofi og pædagogik er gamle fæller, og der er et overlap mellem filosofiens historie og pædagogikkens historiske litteratur. Store tænkere som Platon, Aristoteles, Augustin, Descartes, Locke, Rousseau, Kant, Hegel, Schleiermacher, Herbart og Dewey hører hjemme begge steder. I den pædagogiske filosofi kan almene teoretiske og praktisk filosofiske spørgsmål udforskes systematisk og historisk. Gennem diskussioner af sådanne spørgsmål kan man forholde sig mere nysgerrigt, bevidst, begrundet og kritisk til pædagogisk praksis såvel som til pædagogisk teori, empiri og undervisningsteknologi. -/- Fællesskabet er (...) ikke uproblematisk. Pædagogik er ikke filosofi, og pædagogisk filosofi ikke kun pædagogik. Både didaktik og almen pædagogik kan komme i konflikt med pædagogisk filosofi. Hvordan kan almene pædagogiske spørgsmål overhovedet belyses filosofisk, og hvad betyder de for filosofien selv? En pædagogisk filosofisk tilgang forandrer kanon i både pædagogik og filosofi. Udvalget af nøgletekster ændres. Emner, der er værd at diskutere, forskydes. Nye forskningsspørgsmål og prioriteringer viser sig. Et pædagogisk perspektiv på filosofiens udvikling vil fremhæve dens bidrag til at forstå ’den pædagogiske problem- og fænomenverden’, ligesom et filosofisk perspektiv på pædagogikken vil flytte – eller rettere udvide – fokus med hensyn til dens idéhistorie såvel som dens aktuelle teoretiske praksis. Som i al anden filosofi kan man i den pædagogiske filosofi diskutere teoretiske og praktiske, såvel som poetiske og æstetiske spørgsmål; men det er typisk med en særlig vinkel, nemlig den pædagogiske. Man kan således diskutere erkendelse, viden og sandhed, ligeså vel som man kan undersøge ret, retfærdighed og skønhed. Ofte vil det være med en særlig tvist. Den pædagogiske filosofi kan vise sig som særegen både ved sin særlige position og ved at relatere sig til det pædagogiske som genstandsfelt. Hvad denne position og dette genstandsfelt egentlig er, er der dog ingen enighed om. Det kan ikke engang siges at være udelukkende pædagogisk defineret, og derfor må den pædagogiske filosofi forholde sig åbent til begge dele. Studier i pædagogisk filosofi indbyder til denne drøftelse. (shrink)

Avez-vous remarqué que dans le monde tout ce qui compte va par quatre? La musique : timbre, harmonie, rythme et mélodie. Le repérage : altitude, latitude, longitude et datation. Les quatre aspects de la cause: pour quoi, avec quoi, par quoi et selon quoi? Les forces de la nature : interactions faible, forte, électromagnétique et gravitationnelle... Les vingt-quatre particules élémentaires qui constituent la matière une famille de six leptons associée à trois familles de quarks. Et aussi la logique d'un discours (...) nuancé : oui, non, oui et non, ni oui ni non. Pourquoi quatre est-il partout? La notion de quaternité apporte une réponse à la fois simple et surprenante à cette question. A partir d'exemples tirés de l'expérience humaine, les auteurs en dégagent les aspects structurels et s'en servent pour approfondir le sens des mathématiques et de divers autres domaines liés à la genèse de la connaissance. Il s'agit d'une nouvelle épistémologie, fondée sur un modèle logique qui complète celui d'Aristote. (shrink)

Contemporary problems associated with the notion of determinism are focused by this symposium in three major areas of inquiry--philosophy, physical science, and law and moral responsibility. Determinism in modern physics is capably analyzed by a number of eminent contributors; but with respect to its significance for a philosophy of nature, little that is new or suggestive emerges from this analysis. The distinction between "hard" and "soft" determinism and its implications in legal and moral contexts provoke the most valuable part of (...) the discussion.--J. F. D. (shrink)

Much ink has been spilt in consideration of the once pervasive reliance on military metaphors to depict the relationships between science and religion in the nineteenth century. This has resulted in historically sensitive treatments of secularization; and the realization that the relationship between science and religion was not a bloody war between intellectual nation states, but a protracted divorce of former partners. Moreover, historians of science have been encouraged to throw off the yoke of the internalism–externalism debate, and to explore (...) the cultural boundaries that impinged upon practitioners of a natural knowledge of the world. Within the historiography of nineteenth-century science, this has resulted in many new perspectives on science and natural knowledge in relation to cultural control and authority. (shrink)
