My apology for reverting to this subject is a recent article by Mr. W. C. F. Walters in the April number of the Classical Quarterly for 1910 on the signatures in the Vatican Codex . Mr. Walters does not seem to have been aware that this manuscript, though not of direct value in the constitution of the text of Livy, is one whose interest from a palaeographical point of view has long been recognized. A number of articles have been written (...) concerning it, most of which deal with the signatures, the subject of Mr. Walters' paper, more fully and more accurately than he has done. Beyond giving the signatures, two of them incorrectly, Walters does nothing more than to conclude that there were eight scribes, who copied 42 quaternions. But a great deal more than this is known about the scribes and the manuscript. In fact, thanks to the ingenious combinations of Chatelain and Traube in piecing together the hints suggested by the signatures, more is known about this particular manuscript and the circumstances under which it was made than is the case with any other manuscript of a classical author of so early a date. It may therefore be worth while to summarize the known data concerning the manuscript, with a brief account of how they were worked out, referring the reader for the details to the articles mentioned in the footnotes.

Makes Schelling’s dialogue Bruno readily accessible to the English-language reader, with valuable commentary on the work itself, which details Schelling’s account of his differences from Fichte.

Part novella, part philosophy, Clara was Schelling's most popular work during his lifetime, and appears here in English for the first time.

Summary In establishing what he called the metaphysics of science , the French naturalist Buffon was confronted with the problem of situating the place occupied by man in the natural world, a problem which ultimately depended on discerning his true nature. The paradox of Descartes' dualism offered various solutions — the extremes being, either to condemn man's material nature as corrupted in order to exalt his spiritual nature as a moral being, as Pascal had done, or to reduce man's pretended (...) spiritual nature to nothing more than a manifestation of his material organization, the solution of La Mettrie. Buffon could accept neither, proves man's duality, and proceeds to establish his gnoseological principle on his critique of these two radical solutions. (shrink)

Let g E(m, n)=o mean that n is the Gödel-number of the shortest derivation from E of an equation of the form (m)=k. Hao Wang suggests that the condition for general recursiveness mn(g E(m, n)=o) can be proved constructively if one can find a speedfunction s s, with s(m) bounding the number of steps for getting a value of (m), such that mn s(m) s.t. g E(m, n)=o. This idea, he thinks, yields a constructivist notion of an effectively computable function, (...) one that doesn't get us into a vicious circle since we intuitively know, to begin with, that certain proofs are constructive and certain functions effectively computable. This paper gives a broad possibility proof for the existence of such classes of effectively computable functions, with Wang's idea of effective computability generalized along a number of dimensions.

This paper deals with a philosophical question that arises within the theory of computational complexity: how to understand the notion of INTRINSIC complexity or difficulty, as opposed to notions of difficulty that depend on the particular computational model used. The paper uses ideas from Blum's abstract approach to complexity theory to develop an extensional approach to this question. Among other things, it shows how such an approach gives detailed confirmation of the view that subrecursive hierarchies tend to rank functions in (...) terms of their intrinsic, and not just their model-dependent, difficulty, and it shows how the approach allows us to model the idea that intrinsic difficulty is a fuzzy concept.
