lecting statistics about missing bindings and macros, and other errors. This guides debugging and development eﬀorts, leading to iterative improvements in both the tools and the quality of the converted corpus. The build system thus serves as both a production conversion engine and software test harness. We have now processed the complete arχiv collection through 2006 consisting of more than 400,000 documents (a complete run is a processor-yearsize undertaking), continuously improving our success rate. We are now able to convert more (...) than 90% of these documents to XHTML+MathML. We consider over 60% to be successes, converted with no or minor warnings. While the remaining 30% can also be converted, their quality is doubtful, due to unsupported macros or conversion errors. (shrink)
The ARXMLIV corpus is a remarkable collection of text containing scientiﬁc mathematical discourse. With more than half a million documents, it is an ambitious target for large scale linguistic and semantic analysis, requiring a generalized and distributed approach. In this paper we implement an architecture which solves and automates the issues of knowledge representation and knowledge management, providing an abstraction layer for distributed development of semantic analysis tools. Furthermore, we enable document interaction and visualization and present current implementations of semantic (...) tools and follow-up applications using this architecture. We identify ﬁve different stages, or purposes, which such architecture needs to address, encapsulating each in an independent module. These stages are determined by the different properties of the document formats used, as well as the state of processing and linguistic enrichment introduced so far. We discuss the need of migration between XML representations and the challenges it would pose on our system, revealing the beneﬁts and trade-off of each format we employ. In the heart of the architecture lies the Semantic Blackboard module. The Semantic Blackboard comprises a system based on a centralized RDF database which can facilitate distributed corpus analysis of arbitrary applications, or analysis modules. This is achieved by providing a document abstraction layer and a mechanism for storing, reusing and communicating results via RDF stand-off annotations deposited in the central database. Achieving a properly encapsulated and automated pipeline from the input corpus document to a semantically enriched output in a state-of-the-art representation is the task of the Preprocessing, Semantic Result and Output Generation modules. Each of them addresses the task of format migration and enhances the document for further semantic enrichment or aggregation. The ﬁfth module, targeting Visualization and Feedback, enables user interaction and display of different stages of processing.. (shrink)
This collection of twenty-two essays was originally published in 1932 but political events brought on its immediate destruction. It is only due to the perseverance of the editor, a Spinoza devotee, that the book is now offered to the public. The articles share the common goal of rendering homage to Spinoza. The most sanguine and perhaps clearest argument is David ben Gurion's attempt to redeem Spinoza from the 17th century ban of the Amsterdam Jewish community and to urge upon (...) contemporary Judaism the dutiful re-examination of this "most original and deep-thinking philosopher" yet sired by the Jewish tradition.--C.

En el mundo occidental, la primera figura que encarna el arquetipo del mediador sapiencial entre la comunidad humana y lo divino es, sin duda, Pitágoras de Samos. Las implicaciones de las doctrinas de este chamán en la historia de las ideas son enormes, pues sus invenciones abarcan todos los campos del saber: matemáticas, astronomía, filosofía, retórica, política, adivinación, medicina y religión. Nada escapa a este sabio griego, al que se atribuye un famoso teorema matemático, las escalas musicales y la idea (...) de la inmortalidad del alma. La primera parte del libro se ocupa de estudiar a Pitágoras como figura carismática y legendaria, la colección de sus enseñanzas, sus aspectos mánticos y políticos y, finalmente, la tradición pitagórica entre la realidad y la falsificación. En la segunda parte se presenta por primera vez, en una nueva traducción anotada, una recopilación de todas las biografías del filósofo: las escritas por Porfirio de Tiro, Jámblico de Calcis y Diógenes Laercio, y, como novedad, la más antigua que se conserva, redactada por el historiador griego Diodoro de Sicilia (s. I a.C.), y la del patriarca Focio de Constantinopla (s. IX). Todo ello, junto a la colección de máximas pitagóricas de origen tardío, llamada Versos de oro, así como el epítome de la enciclopedia bizantina Suda (s. X), forma el presente corpus biográfico-doctrinal de Pitágoras, que era una labor pendiente en el panorama bibliográfico español. David Hernández de la Fuente (Madrid, 1974) es escritor y profesor universitario, especializado en religión griega, antigüedad tardía e historia del platonismo. Doctor en filología clásica y sociología, es autor de los ensayos Oráculos griegos (Alianza) y Bakkhos Anax (CSIC), así como de numerosos artículos en revistas académicas y ediciones de autores clásicos, y ha coordinado la obra colectiva New Perspectives on Late Antiquity (Cambridge Scholars Pub.). Como autor de narrativa ha publicado Las puertas del sueño (Premio de Arte Joven 2005 de la Comunidad de Madrid), Continental (2007) y A cubierto (Premio Diputación de Valencia 2010).

The revival of analytic metaphysics in the latter half of the twentieth century is typically understood as a consequence of the critiques of logical positivism, Quine’s naturalization of ontology, Kripke’s Naming and Necessity, clarifications of modal notions in logic, and the theoretical exploitation of possible worlds. However, this explanation overlooks the work of metaphysicians at the height of positivism and linguisticism that affected metaphysics of the late twentieth century. Donald C. Williams is one such philosopher. In this paper I explain (...) how Williams’s fundamental ontology and philosophy of time influenced in part the early formation of David Lewis’s metaphysics. Thus, Williams played an important role in the revival of analytic metaphysics. (shrink)
C. S. Lewis is one of the most beloved Christian apologists of the twentieth century; David Hume and Bertrand Russell are among Christianity's most important critics. This book puts these three intellectual giants in conversation with one another to shed light on some of life's most difficult yet important questions. It examines their views on a variety of topics, including the existence of God, suffering, morality, reason, joy, miracles, and faith. Along with irreconcilable differences and points of tension, some (...) surprising areas of agreement emerge. Today, amidst the often shrill and vapid exchanges between 'new atheists' and twenty-first-century believers, curious readers will find penetrating insights in the reasoned dialogue of these three great thinkers.

At first glance, it might seem strange to consider Derrida as an environmental philosopher. There is still a sense with many that Derrida is primarily a thinker of poetry and texts rather than of “leaves or soil”. While this is still a common view, even a cursory glance at Derrida’s work and at this volume shows that it is based on a misunderstanding. What it ignores is the fact that ‘text’ for Derrida is “coextensive [at least, T.B.] with mortal life” (...) and indeed can be said to include every aspect of the world. Moreover, Derrida challenges the idea that we can understand culture independently from its material manifestations in the world and from its relations... (shrink)
Germ-line therapy has long been regarded with great caution both by scientists and by ethicists. Even those who do not reject germ-line therapy in principle have tended to reject it in practice as carrying unacceptable risks in our current state of knowledge. For this reason, a recent paper by Rubenstein, Thomasma, Shon, and Zinaman is unusual in putting forward a serious proposal for the use of germ-line therapy in the foreseeable future.
Technical, ethical, and social questions of germ-line gene interventions have been widely discussed in the literature. The majority of these discussions focus on planned interventions executed on the nuclear DNA (nDNA). However, human cells also contain another set of genes that is the mitochondrial DNA (mtDNA). As the characteristics of the mtDNA grossly differ from those of nDNA, so do the social, ethical, psychological, and safety considerations of possible interventions on this part of the genetic substance.
