One of the most interesting jurists of the post-World War II era, Ross [1899-1979] was a legal and moral philosopher, scholar of international law and the leading representative of Scandinavian Legal Realism. This book and On Law and Justice (1958) are (...) his principal works. In Directives and Norms Ross asks whether imperatives (or, to use his term, 'directives') are subject to logic in the same way as indicatives. He shows the difference between indicative and directive discourse and explains the concepts 'directive' and 'norm' as they function in the social sciences, especially in the study of law. A contemporary essay in the Modern Law Review (32:544), though critical of this work, was still impressed by its "clear and convincing account" of these processes. (shrink)

We prove that for every Scott set S there are S-saturated real closed fields and S-saturated models of Presburger arithmetic.

We develop a new notion of independence (þ-independence, read "thorn"-independence) that arises from a family of ranks suggested by Scanlon (þ-ranks). We prove that in a large class of theories (including simple theories and o-minimal theories) this notion has many of the properties needed for an adequate geometric structure. We prove that þ-independence agrees with the usual independence notions in stable, supersimple and o-minimal theories. Furthermore, we give some evidence that the equivalence between forking and þ-forking in simple theories might (...) be closely related to one of the main open conjectures in simplicity theory, the stable forking conjecture. In particular, we prove that in any simple theory where the stable forking conjecture holds. þ-independence and forking independence agree. (shrink)

This article applies some conceptual tools from semiotics to better understand the disastrous impacts of the world economy on global ecology. It traces the accelerating production of material disorder and waste to the logic of the money sign, as economic production processes simultaneously increase exchange-values and entropy. The exchange of indexical and iconic signs is essential to the dynamics of ecological systems and the proliferation of biological diversity. The human species has added a third kind of sign, the symbol, and (...) more recently a fourth: all-purpose money. Money does not refer to any referent either through contiguity, similarity, or convention. It is an empty sign, capable of assuming any significance that its owner attributes to it. The article argues that the concept of symbolic reference should be restricted to cultural and linguistic phenomena. Money qualifies as a new species of sign based on its exceedingly open mode of reference. It does not refer to any object by social convention but owes its specific properties precisely to the absence of such conventions. The logic of money pivots on decontextualisation: it presupposes and encourages the detachment of exchange values, people, and concepts from the particular and the local. Selective advantage is no longer primarily about calibration within local contexts, but increasingly a matter of transcending or emancipating oneself from the specific. This drift toward decontextualisation reverses the evolution of complexity and diversity throughout the planetary biosphere. (shrink)

Though media ethics has emerged as a strong topic in recent years, the discussion may be of little value in helping improve ethical performance of the media until owner ethics becomes a major topic. This case study explores the conflict of interest problem for owners lobbying for special interest legislation and eroding independence of newsrooms.

We study dp-minimal and strongly dependent theories and investigate connections between these notions and weight.

O-minimal structures have long been thought to occupy the base of a hierarchy of ordered structures, in analogy with the role that strongly minimal structures play with respect to stable theories. This is the first in an anticipated series of papers whose aim is the development of model theory for ordered structures of rank greater than one. A class of ordered structures to which a notion of finite rank can be assigned, the decomposable structures, is introduced here. These include all (...) ordered structures definable in o-minimal structures. The principal result in this paper, Theorem 5.1, asserts roughly that a decomposable structure [Formula: see text] can be partitioned into finitely many definable subsets such that on each set the restriction of < is a "twisted lexicographic" order. As a consequence, for all n and linear orders ≺ definable on a subset X ⊆ Mn in an o-minimal structure [Formula: see text], there is a definable partition of X such that the restriction of ≺ to each set in the partition is "lexicographic".

The existing literature treats of several investigations with a certain bearing on the question which is roughly indicated by the title “Imperatives and Logic.” Some of those investigations, however, are entirely outside the scope of the present work.Mally sets himself the task of developing a “Logik des Willens” constituting a parallel to the usual logic, the “Logik des Denkens". In order to emphasize its independence, the author also calls this “Logik des Willens” “Deontik”, and he conceives it as being based (...) on the “Wesensgesetze” of will in the same way as the usual logic is conceived as being based on the “Wesensgesetze” of thought. The author develops a formalistic deductive system on the basis of 5 axioms of demands, including the axiom that there is at least one fact which is unconditionally demanded, and through a lengthy series of theorems he arrives at the sentence that what is unconditionally demanded is identical with what is actually the case: “was sein soll, ist Tatsache”. Similarly, the author develops a system of axioms for “right” volition, including the axiom that right volition is non-contradictory. (shrink)

This essay proposes that management is too often seen as problem solving, and that the equally important art of ignoring problems has not received enough attention. With reference to the thinking of Ludwig Wittgenstein, the essay argues for letting go, and attempting to leave thoughts at rest.

This edition contains the correspondence between Paul Tillich and his friend Fedor Stepun, a sociologist and philosopher of religion. Tillich and Stepun had been colleagues at Technische Universität Dresden in the mid 1920s. The correspondence covers the period between 1934 and 1964. The early letters address the situation in Germany during the onset of National Socialism: the so-called Röhm-Putsch, the Kirchenkampf, the institutional changes in the university system and, later, the dismissal of Stepun as professor in Dresden in 1937. After (...) a hiatus of several years, the correspondence continues in 1946. The correspondence shows the search for a new positioning in the postwar years, from the perspective of the émigré Paul Tillich and Stepun, the expert on Russia, who from Munich observed the political developments of the Cold War with great concern. Stepun consistently proves an acute critic of the political theologian Paul Tillich. In particular, Tillich's Christology and his program of religious socialism met with his friend's fierce criticism. (shrink)

Edited in this contribution are eighteen of August Tholuck's letters to Friedrich Lücke from 1827 to 1854, which were recently discovered in Göttingen's municipal archives. In addition, ten of Lücke's replies that were made available by the Franckesche Stiftungen in Halle now receive their necessary supplementation. In its introduction and critical commentary the paper focuses on and elucidates the exegesis of St John's Gospel, theological Hegelianism and Lücke's appointment from Göttingen to Halle in 1838.

Release of the ATP hydrolysis product ortophosphate (Pi) from the active site of myosin is central in chemo‐mechanical energy transduction and closely associated with the main force‐generating structural change, the power‐stroke. Despite intense investigations, the relative timing between Pi‐release and the power‐stroke remains poorly understood. This hampers in depth understanding of force production by myosin in health and disease and our understanding of myosin‐active drugs. Since the 1990s and up to today, models that incorporate the Pi‐release either distinctly before or (...) after the power‐stroke, in unbranched kinetic schemes, have dominated the literature. However, in recent years, alternative models have emerged to explain apparently contradictory findings. Here, we first compare and critically analyze three influential alternative models proposed previously. These are either characterized by a branched kinetic scheme or by partial uncoupling of Pi‐release and the power‐stroke. Finally, we suggest critical tests of the models aiming for a unified picture.

We develop the theory of domination by stable types and stable weight in an arbitrary theory.

A review of the scanty Gestaltist literature on motor behaviour indicates that a genuine Gestalt theoretic approach to motor behaviour can be characterized by three research questions: (1) What are the natural units of motor behaviour? (2) What characterizes the self-organization in motor behaviour? (3) What are the conditions for invariance in motor behaviour? Tentative answers to these questions can be found by analysing the parallels between Gestalt theory and Bernstein's theory of motor actions and by showing that Gestalt theory (...) can be regarded as a specific approach to non-linear dynamics as exemplified by synergetics (Haken, 1991). The congruence between the Gestalt theoretic approach and synergetics becomes apparent in the analysis of how a complex motor task is learned [1]. (shrink)

Let M be an arbitrary structure. Then we say that an M -formula φ defines a stable set inM if every formula φ ∧ α is stable. We prove: If G is an M -definable group and every definable stable subset of G has U -rank at most n , then G has a maximal connected stable normal subgroup H such that G /H is purely unstable. The assumptions hold for example if M is interpretable in an o-minimal structure.More generally, (...) an M -definable set X is weakly stable if the M -induced structure on X is stable. We observe that, by results of Shelah, every weakly stable set in theories with NIP is stable. (shrink)

This article challenges the urge within Actor-Network Theory, posthumanism, and the ontological turn in sociology and anthropology to dissolve analytical distinctions between subject and object, society and nature, and human and non-human. It argues that only by acknowledging such distinctions and applying a realist ontology can exploitative and unsustainable global power relations be exposed. The predicament of the Anthropocene should not prompt us to abandon distinctions between society and nature but to refine the analytical framework through which we can distinguish (...) between sentience and non-sentience and between the symbolic and non-symbolic. The incompatibility of posthumanist and Marxist approaches to the Anthropocene and the question of agency derives from ideological differences as well as different methodological proclivities. A central illustration of these differences is the understanding of fetishism, a concept viewed by posthumanists as condescending but by Marxists as emancipatory. (shrink)

This paper is devoted to understand groups definable in Presburger Arithmetic. We prove the following theorems: Theorem 1. Every group definable in a model of Presburger Arithmetic is abelian-by-finite. Theorem 2. Every bounded abelian group definable in a model of (Z, +, <) Presburger Arithmetic is definably isomorphic to (Z, +)^n mod out by a lattice.

This edition, which follows a paper on the relationship between Paul Tillich and Fritz Medicus, presents their till now largely unpublished correspondence. The letters are supplemented by other significant documents from the Andover-Harvard Theological Library, the Swiss Federal Institute of Technology Zurich, and the university archives of Jena and Halle.

This paper is concerned to take a closer look at the relations between Paul Tillich and Fritz Medicus, his philosophical teacher in Halle. The center of attention is on their orientation within neo-Kantianism and the Fichte and Schelling renaissance. A collection of letters and other documents reflects their involvement in events of contemporary history, their respective literary works, and an ongoing friendship.
