The impossibility theorem of Dekel, Lipman and Rustichini has been thought to demonstrate that standard state-space models cannot be used to represent unawareness. We first show that Dekel, Lipman and Rustichini do not establish this claim. We then distinguish three notions of awareness, and argue that although one of them may not be adequately modeled using standard state spaces, there is no reason to think that standard state spaces cannot provide models of the other two notions. In fact, standard space (...) models of these forms of awareness are attractively simple. They allow us to prove completeness and decidability results with ease, to carry over standard techniques from decision theory, and to add propositional quantifiers straightforwardly. (shrink)

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 two main ways to teach a course online: synchronously or asynchronously. In an asynchronous course, students can log on at their convenience and do the course work. In a synchronous course, there is a requirement that all students be online at specific times, to allow for a shared course environment. In this article, the author discusses the strengths and weaknesses of synchronous online learning for the teaching of undergraduate philosophy courses. The author discusses specific strategies and technologies he (...) uses in the teaching of online philosophy courses. In particular, the author discusses how he uses videoconferencing to create a classroom-like environment in an online class. (shrink)

The bestseller The Courage to Be presents Tillich’s “concrete existential” notion of religion that is based on the key terms ‘anxiety’ and ‘courage’. This essay traces this idea’s long history in Tillichian thinking that reaches back to the mid-twenties lectures on dogmatics in Marburg and Dresden, and outlines its core elements, pointing out its contrast to Tillich’s earlier notion of religion as the mind’s intention on absolute meaning. Subsequently, the discussion moves to Tillich’s theorem of the double principle of ‘individualization (...) and participation’, providing instructive insights into basic social presuppositions and types of religion, instructive especially in the present-day situation of religious pluralism.

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.

Die Sprachlichkeit des Glaubens ist von Anfang an zentrales Thema protestantischer Theologie. Der Glaube, als Vertrauen auf das biblisch bezeugte und lebendig gepredigte Evangelium, lebt in der Sprache, weil er aus dem Horen kommt: Er vollzieht sich im Modus des Verstehens. Seit jeher sind daher theologische Hermeneutik und Homiletik Orte, an denen die Sprachlichkeit des Glaubens reflektiert wird. Diese Reflexion setzen die Beitrage des vorliegenden Bandes in je unterschiedlicher Facherperspektive fort.

Review of Marcus Arvan, Rightness as Fairness.

This volume explores the use of higher-order logics in metaphysics. Seventeen original essays trace the development of higher-order metaphysics, discuss different ways in which higher-order languages and logics may be used, and consider their application to various central topics of metaphysics.
