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)

In the opening chapter of the Iudicium de Dinarcho Dionysius quotes a passage from the Περì μωνμων of Demetrius Magnes, mat the end of which come the words δ λξις ςτ το Δεινρχου κυρως θικ πθος κινοσα σχεδòν τ πικρí μóνον καì τ τóν το Δημοσθθενικο χαρακτρος λειπομνη το δ πιθανο καì κυρíιυ μηδν νδονσα. [I have deliberately omitted all punctuation marks, because the punctuation of this sentence is still doubtful, though I hope to suggest a possible interpretation of its (...) meaning at the end of this article.] Now there is nothing in this sentence or in the words preceding it to indicate beyond all possibility of doubt the precise meaning ofκυρíως θικ. And in such circumstances, to allow free play to personal prejudices regarding the significance of thephrase is more than dangerous. The whole problem of θικ λξις has been treated too cursorily. If one mentions the phrase to a non-professional student of Greek, who, however, has some acquaintance with the Attic orators, he immediately replies: ‘I suppose you mean the sort of thing you meet in Lysias.’ And he is to beexcused, because, after all, that is the predominant meaning of the term. But it has other senses, and therefore one must fight shy of vague statements like that of Finke, who, after quoting the above lines, comment: ‘Demetrius Magnus attribuit ei τν κυρíαν λξιν qua non sit Demosthene inferior’; or of Burgess, who enumerates qualities, ideas, and topics ‘of special value to the epideictic and court orators, ’ among which appears θοποια which he merely translates ‘impersonation or delineation of character, ’ without offering any further comment. Sandys talks of ‘the ethical warmth of colouring, by which the dullest details are lit up with a fresh life and interest.’ Gromska is even more vague (and seems almost to confuse θς and χαρακτρ: ‘Grammatici antiqui, qui de Hyperide tractabant, de eloquentiae eius genere disputabant, orationum Hyperidearum compositionem et θς respicientes, i.e. quantum in arte rhetorica et oratoria valeret, examinantes.’ In the hope, therefore, of being able to represent the difficulty inherent in these lines, and of attempting to remove it, or at any rate to shed a broader beam of light upon it than has been shed hitherto, I propose to review very briefly the fluctuations of meaning in the life of this phrase and its equivalents, as we find them used in the critical writings of the Greek philosophers and rhetoricians.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

A study in philosophical logic of the meaning of 'true'. Dr Williams demonstrates the shortcomings of various analyses which interpret 'true' as a predicate or truth as a relational property, and clears up a number of important points about propositions, quantification, definite descriptions and correspondence. This 'deflationary metaphysics' is interwoven with a positive theory of his own, which seeks to develop ideas about the late Arthur Prior. The work is marked throughout by great clarity, precision and thoroughness.

ABSTRACT In this paper we attempt to sharpen and to provide an answer to the question of when human beings first become conscious. Since it is relatively uncontentious that a capacity for raw sensation precedes and underpins all more sophisticated mental capacities, our question is tantamount to asking when human beings first have experiences with sensational content. Two interconnected features of our argument are crucial. First, we argue that experiences with sensational content are supervenient on facts about electrical activity in (...) the cerebral cortex which can be ascertained through EEG readings. Second, we isolate from other notions of a‘functioning brain’that which is required to underpin the view that a cortex is functioning in a way which could give rise to rudimentary conscious experiences. We investigate the development in the human fetus of the anatomical and chemical pathways which underpin (immature) cortical activity and the growth and maturation of the electrical circuitry specifically associated with sensational content in adult experience. We conclude (tentatively) that a fetus becomes conscious at about 30 to 35 weeks after conception; an answer based on a careful analysis of EEG readings at various stages of cortical development. Finally, we survey the possible ethical ramifications of our answer. (shrink)

We extend results of Harizanov and Barker. For a relation R on a recursive structure /oA, we give conditions guaranteeing that the image of R in a recursive copy of /oA can be made to have arbitrary ∑α0 degree over Δα0. We give stronger conditions under which the image of R can be made ∑α0 degree as well. The degrees over Δα0 can be replaced by certain more general classes. We also generalize the Friedberg-Muchnik Theorem, giving conditions on a pair (...) of relations R and S under which the images of R and S can be made ∑α0 and independent over Δα0 in a recursive copy of /oA.

Let be a recursive structure, and let R be a recursive relation on . Harizanov isolated a syntactical condition which is necessary and sufficient for to have recursive copies in which the image of R is r.e. of arbitrary r.e. degree. We had conjectured that a certain extension of Harizanov's syntactical condition would be necessary and sufficient for to have recursive copies in which the image of R is ∑α0 of arbitrary ∑α0 degree, but this is not the case. Here (...) we give examples illustrating some restrictions on the possible ∑α0 degrees. In these examples, the image of R cannot be ∑α0 of degree d unless d possesses an “α-table”. (shrink)
