So far, little is known about the neurocognitive mechanisms associated with emotion effects on prospective memory (PM) performance. Thus, this study aimed at disentangling possible mechanisms for the effects of emotional valence of PM cues on the distinct phases composing PM by investigating event-related potentials (ERPs). Participants were engaged in an ongoing N-back task while being required to perform a PM task. The emotional valence of both the ongoing pictures and the PM cues was manipulated (pleasant, neutral, unpleasant). ERPs were (...) recorded during the PM phases, such as encoding, maintenance, and retrieval of the intention. A recognition task including PM cues and ongoing stimuli was also performed at the end of the sessions. ERP results suggest that emotional PM cues not only trigger an automatic, bottom-up, capture of attention, but also boost a greater allocation of top-down processes. These processes seem to be recruited to hold attention towards the emotional stimuli and to retrieve the intention from memory, likely because of the motivational significance of the emotional stimuli. Moreover, pleasant PM cues seemed to modulate especially the prospective component, as revealed by changes in the amplitude of the ERP correlates of strategic monitoring as a function of the relevance of the valence for the PM task. Unpleasant pictures seemed to modulate especially the retrospective component, as revealed by the largest old/new effect being elicited by unpleasant PM pictures in the recognition task. (shrink)

We give examples of calculi that extend Gentzen’s sequent calculusLKby unsound quantifier inferences in such a way that derivations lead only to true sequents, and proofs therein are nonelementarily shorter thanLK-proofs.

Assuming an essential difference between scientific data and phenomena, this paper argues for the view that we have to understand how empirical findings get transformed into scientific phenomena. The work of scientists is seen as largely consisting in constructing these phenomena which are then utilized in more abstract theories. It is claimed that these matters are of importance for discussions of theory choice and progress in science. A case study is presented as a starting point: paleomagnetism and the use of (...) paleomagnetic data in early discussions of continental drift. Some general features of this study are presented in formalized language. It is suggested that the presentation given is particularly suited for a semantic conception of theories. Even though the construction of scientific phenomena is the main topic of this paper, the view presented here is more adapted to realism than social constructivism. (shrink)

This book considers Robert Brandom's philosophy and presents an original and exciting analysis of the semantic argument in legal argumentation.

The conflict over the classic problem of philosophical anthropology, i. e., what man actually is, is not only a conflict about what – X – determines something to be human. It also requires clarification of the manner in which something is determined to be human by the X in question. There being different options for the latter, the classic anthropological conflict concerns not only definitions of being human, but also models of being human. The present paper investigates four such models: (...) the addition model, the interior model, the privation model, and the transformation model. While the first will serve as a baseline for comparison, the three other models will, in order to escape the danger of making too formal an argument, be discussed exemplarily, i. e. by focusing in each case on a certain proponent of the respective model. Those proponents will be Martin Heidegger for the interior model, Arnold Gehlen for the privation model, and Helmuth Plessner for the transformation model. (shrink)

Meanings are felt and lived by the human organism before they are articulated. Following insights from pragmatism and embodied cognition, this paper suggests that there is an ‘appropriate’ relationship between what is meant and was is expressed in words and actions that can be formulated as a hitherto neglected yet crucial validity claim, namely congruity. Congruity is what connects the meaningfulness implicit in living a life with the articulated meanings of symbolic communication. We distinguish between the intertwined aspects of semiotic (...) congruity, the fusion between sensual patterns and semiotic meanings, performative congruity, the freedom and ability to articulate qualitatively experienced meaningfulness, and hermeneutic congruity, the capability of achieving congruence between situational meanings and one’s entire being-in-the-world. The latter presupposes a synthesis of horizontal and vertical congruity. (shrink)

Nelson Goodman cast the ‘problem of induction’ as the task of articulating the principles and standards by which to distinguish valid from invalid inductive inferences. This paper explores some logical bounds on the ability of a rational reasoner to accomplish this task. By a simple argument, either an inductive inference method cannot admit its own fallibility, or there exists some non-inferable hypothesis whose non-inferability the method cannot infer (violating the principle of ‘negative introspection’). The paper discusses some implications of this (...) limited self-knowledge for the justifiability of inductive inferences, auto-epistemic logic, and the epistemic foundations of game theory.

In “Agreeing to Disagree” [1], Robert Aumann proves that a group of agents who once agreed about the probability of some proposition for which their current probabilities are common knowledge must still agree, even if those probabilities reflect disparate observations. Perhaps one saw that a card was red and another saw that it was a heart, so that as far as that goes, their common prior probability of 1/52 for its being the Queen of hearts would change in the one (...) case to 1/26, and in the other to 1/13. But if those are indeed their current probabilities, it cannot be the case that both know them, and both know that both know them, etc., etc. (shrink)

Das Kernanliegen der philosophischen Arbeiten Ludwig Sieps ist die Formulierung einer praktischen Philosophie für die Gegenwart. In seinen jüngeren Arbeiten sind insbesondere der Begriff der Natur und der Begriff der Erfahrung in den Fokus gerückt. Eine plausible Ethik muss nach Siep einerseits eine evaluative Naturbetrachtung und insbesondere eine Reflexion der Natur des Menschen umfassen. Andererseits muss sie aber auch, weil sie sich nicht auf apriorische Prinzipien stützen kann, ein Konzept der historischen Erfahrung heranziehen, wenn sie Antworten auf die heute relevanten (...) Fragen geben möchte. Der Band behandelt anlässlich des 75. Geburtstages Ludwig Sieps zentrale Aspekte seiner jüngeren Arbeiten, teils kritisch und teils mit Vorschlägen für mögliche Weiterentwicklungen. Ziel dieser Auseinandersetzung mit dem philosophischen Denken Ludwig Sieps ist es, entlang der systematischen Linien »Natur« und »Erfahrung« Bausteine zu einer praktischen Philosophie der Gegenwart zu diskutieren.

Freges Kontextprinzip "Nur im Zusammenhange eines Satzes bedeuten die Wörter etwas" hat auch nach der von ihm vollzogenen Angleichung von Behauptungssätzen an Eigennamen Gültigkeit für die formale Sprache der "Grundgesetze". Der Bedeutungsvollständigkcitsbeweis, den er für sein Logiksystem anstrebt, schließt eine unmittelbare Anwendung dieses Prinzips nicht nur auf die unvollständigen Funktionsausdrücke, sondern auch auf die leerstellenfreien Wertverlaufsnamen ein. Wahrheitsnamen (Sätze) zeichnen sich vor anderen symbolsprachlichen Eigennamen in mehrfacher Hinsicht, insbesondere durch ihre semantische Selbständigkeit aus. Wertverlaufsnamen haben nur im Zusammenhang eines Wahrheitswertnamens (...) eine Bedeutung. Ihre Bedeutung besteht in ihrem Beitrag zur Bestimmung der Bedeutung von Wahrheitswertnamen, in denen sie vorkommen. (shrink)

Der vorliegende Band diskutiert die Geschichts- und Sprachphilosophie Giambattista Vicos, primär in Bezug auf die Rechtslehre. Dabei wird Vico sowohl als Denker seines Zeitalters als auch in der Auseinandersetzung mit Autoren wie Suárez, Bacon, Descartes etc. gelesen und es ergeben sich immer wieder Bezüge zu aktuellen Debatten.

We judge actions to be rational if means are adequate to ends. In modern societies, innumerable actions are interconnected into complex systems. Does rationality, then, become a feature of systems? If so, it will not do to view means in the light of ends, Niklas Luhmann maintained. In ‘The Concept of Purpose and Systems Rationality’ (‘Zweckbegriff und Systemrationalität’) (1968), he defined the rationality of systems as their capacity to reduce complexity (“Reduktion von Komplexität”); in his later work, Luhmann elaborated and (...) partly transformed that account. Dorschel and Kettner put his views under scrutiny. (shrink)

This article addresses two shortcomings in the literature on nationalism: the need to theorize transformations of nationalism, and the relative absence of comparative works on Latin America. We propose a state-focused theoretical framework, centered on conflicts between states elites and social movements, for explaining transformations of nationalism. Different configurations of four key factors — the mobilization of excluded elites and subordinate actors, state elites’ political control, the ideological capacities of states, and polarization around ethnoracial cleavages — shape how contrasting trajectories (...) of nationalism unfold over time. A comparative analysis of early– and mid–twentieth century Mexico, Argentina, and Peru illustrates the explanatory power of our theoretical framework. (shrink)

Alle kulturellen Praktiken sind verkörpert: Ihnen ist die Spannungseinheit von leiblichem Erleben, physischem Tun und kulturellem Sinn eingeschrieben. Von den Kognitions- bis zu den Kulturwissenschaften ist Verkörperung daher mittlerweile ein zentrales Forschungsthema. Der vorgelegte Band widmet sich in interdisziplinärer Perspektive exemplarischen Praktiken und Ritualen des Körpers und will einem drohenden neuen Dualismus zwischen leiblicher und kultureller Verkörperung entgegenwirken. Biologischer Organismus, bewusstes Erleben und kulturelle Traditionen sollen in ihrer Wechselbezüglichkeit hervortreten und damit sichtbar machen, dass „Sinn“ ein Phänomen ist, das die (...) cartesianische Trennung von Geist und Körper unterläuft.

I discuss Wolfgang Tress’ attempt to apply analytic philosophy to the field of psychiatry and psychological medicine. According to Tress the concept of a person as a rational intentional system is fundamental for psychological medicine and irreducible to concepts of the natural sciences. But the rationality assumptions that are crucial for the concept of a person need much more clarification than Tress provides. Furthermore, Tress’ concept of schizophrenia as a disorder of ‘semantic coherence of the person’ is seriously flawed empirically. (...) Pragmatics rather than semantics should provide the methodological framework for the reconstruction of psychopathological concepts, such as “schizophrenia” and “delusion”. (shrink)

Neo-logicism is, not least in the light of Frege’s logicist programme, an important topic in the current philosophy of mathematics. In this essay, I critically discuss a number of issues that I consider to be relevant for both Frege’s logicism and neo-logicism. I begin with a brief introduction into Wright’s neo-Fregean project and mention the main objections that he faces. In Sect. 2, I discuss the Julius Caesar problem and its possible Fregean and neo-Fregean solution. In Sect. 3, I raise (...) what I take to be a central objection to the position of neo-logicism. In Sect. 4, I attempt to clarify how we should understand Frege’s stipulation that the two sides of an abstraction principle qua contextual definition of a term-forming operator shall be “gleichbedeutend”. In Sect. 5, I consider the options that Frege might have had to establish the analyticity of Hume’s Principle: The number that belongs to the concept F is equal to the number that belongs to the concept G if and only if F and G are equinumerous. Section 6 is devoted to Frege’s two criteria of thought identity. In Sects. 7 and 8, I defend the position of the neo-logicist against an alleged “knock-down argument”. In Sect. 9, I comment on Frege’s description of abstraction in Grundlagen, §64 and the use of the terms “recarving” and “reconceptualization” in the relevant literature on Fregean abstraction and neo-logicism. I argue that Fregean abstraction has nothing to do with the recarving of a sentence content or its decomposition in different ways. I conclude with remarks on global logicism versus local logicisms.

This is a review of: God's Rational Warriors: The Rationality of Faith Considered.

In this article it is argued that a continuity exists between Karl Schwarzschild's work on foundational problems on the borderline of physics and astronomy and his later occupation with general relativity. Based on an analysis of Schwarzschild's published works as well as formerly neglected unpublished notes it is shown that, long before the rise of general relativity, Schwarzschild was concerned with problems that later became associated with that theory. In particular he considered non-Euclidean cosmologies, linked the phenomena of gravitation and (...) inertia to the problem of the precession of Mercury's perihelion, and entertained the possibility of inertial frames rotating with respect to one another. It is argued that these earlier considerations, which reflect his interdisciplinary outlook on the foundations of the exact sciences, enabled Schwarzschild to recognize the significance of general relativity for astronomy, astrophysics, and cosmology earlier than most of his collegues and shaped his contributions to this theory.

In his paper `Finitism', W.W.~Tait maintained that the chief difficulty for everyone who wishes to understand Hilbert's conception of finitist mathematics is this: to specify the sense of the provability of general statements about the natural numbers without presupposing infinite totalities. Tait further argued that all finitist reasoning is essentially primitive recursive. In our paper, we attempt to show that his thesis ``The finitist functions are precisely the primitive recursive functions'' is disputable and that another, likewise defended by him, is (...) untenable. The second thesis is that the finitist theorems are precisely those $\Pi^0_1$-sentences that can be proved in. (shrink)
