According to the algebraic approach to spacetime, a thoroughgoing dynamicism, physical fields exist without an underlying manifold. This view is usually implemented by postulating an algebraic structure (e.g., commutative ring) of scalar-valued functions, which can be interpreted as representing a scalar field, and deriving other structures from it. In this work, we point out that this leads to the unjustified primacy of an undetermined scalar field. Instead, we propose to consider algebraic structures in which all (and only) physical fields are (...) primitive. We explain how the theory of natural operations in differential geometry—the modern formalism behind classifying diffeomorphism-invariant constructions—can be used to obtain concrete implementations of this idea for any given collection of fields. For concrete examples, we illustrate how our approach applies to a number of particular physical fields, including electrodynamics coupled to a Weyl spinor. (shrink)

There are words. There are sentences. There are languages. Commonsense linguistic realism is the conjunction of the three preceding claims. Linguists and philosophers including Noam Chomsky (1986, 2000), Georges Rey (2006, 2008), and Barry C. Smith (2006) have presented skeptical doubts regarding the existence of linguistic entities. These doubts provide no good reason to deny commonsense linguistic realism. Some skeptical doubts are in fact not directed at the metaphysical thesis of commonsense linguistic realism but rather only at non-metaphysical methodological concerns. (...) In some instances, linguistic antirealists make their case by foisting upon the realist assumptions that she need not hold regarding the nature of linguistic entities. Furthermore, those who have denied the existence of linguistic entities have not themselves presented an alternative account of words, sentences, or languages that is coherentor defensible. I present an elaboration and defense of commonsense linguistic realism as a metaphysical thesis, with the aim of deflating concerns that have arisen about the existence of language. (shrink)

Pour interpréter les paroles d’institution, et notamment la phrase attribuée au Christ « ceci est mon corps », les réformateurs ont utilisé la rhétorique de leur temps. De même, les éléments de la Cène ont été compris par eux comme des signes, à la lumière d’une « sémiotique » de leur époque et en anticipant des réflexions qui se répandront dans les siècles ultérieurs. Dès lors il est tentant de relire le débat réformateur au sujet de la Cène à la (...) lumière de certains éléments de linguistique du XXe siècle, pour dégager certains enjeux théologiques d’une compréhension du langage. Le présent article fait donc état du versant linguistique du conflit sacramentel entre luthériens et réformés, en essayant de voir le lien entre le langage et la manière de se situer devant Dieu qui est en jeu. La question de la figure rhétorique utilisée par le Christ ayant d’abord été posée par les réformés, l’article propose pour commencer l’étude de la doctrine de Calvin avant de passer à Luther et son anticipation de la notion contemporaine de « parole performative », pour terminer sur différents enjeux du contexte actuel.To interpret the words of institution, and especially the phrase attributed to Christ “This is my body,” the reformers used the rhetoric of their day. The elements of the Last Supper were likewise understood by them as signs, in the light of a “semiotic” of the era and in analysing reflections that would continue to develop in later centuries. It is tempting to reread the reformer’s debate concerning the Last Supper in the light of certain elements of 20th century linguistics, to open up certain theological problems that involve the comprehension of language. The present article, then, takes into account the linguistic dimension of the sacramental debate between Lutherans and Reformists in trying to see the connection between language and the manner one positions himself before God Who is the issue. As to the question of the rhetorical figure used by Christ first proposed by the Reformists, this article begins by studying Calvin’s doctrine, then moves on to Luther and his anticipation of the contemporaneous notion of the “performative word,” and ends with the various issues in today’s context.

The main theses advocated here run as follows: Medieval literature rests on ›Weltanschauung‹ and literary theory of Antiquity and Christianity, even when it is no longer Latin but vernacular literature. It adheres to tradition, not least by clinging to principal genres, especially to fabula and historia in the field of narrative. The modern ›willing suspension of disbelief‹ does not exist yet. Latin tradition influences Germanic literature either direct or via Romanic literatures. Research must take the same way instead of analyzing (...) old texts with the help of modern methods, which were successfully applied to modern texts. (shrink)

The process of theory development in physics is a very complex one. The best scientists sometimes proceed on the basis of their physical intuition, ignoring serious conceptual or mathematical objections well known to them at the time.The results soon justify their actions: but the removal of these objections is often not possible for a very long time. Four examples are presented: Newton, Schrödinger, Dirac, Dyson. Some thoughts on this “unreasonableness≓ are offered.
