It has often been pointed out that the Marxian theory of value contains some inconsistencies, usually in relation to the concept of abstract labour. However, the contradiction between the concept of labour and the concept of validity with which Marx operates in Capital has never been discussed. A detailed analysis shows that this concept of validity refers to the process of abstraction which is carried out by the participants of the exchange process. Only the rigorous comprehension of this process of (...) abstraction can illuminate that for which the concept of abstract labour was developed: the unity and universality of value. On this basis, the paper criticises the Marxian development of the money-form and presents an alternative approach that builds on the aforementioned concept of validity. This concept is formulated in more depth by recourse to the works of Hegel, Simmel and Adorno. Furthermore, the paper reconsiders the dialectical development of categories in the light of this alternative conception of the money-form as totality and abstraction. Finally, the distinction between simple circulation and the process as a whole is explored and it is argued that, according to the novel reading proposed, it acquires a fundamental significance.

Art can be experienced in numerous ways, ranging from sensory pleasure to elaborated ways of finding meaning (Leder et al. 2004). However, rather ignored by Bullot & Reber (B&R), in empirical aesthetics several lines of research have studied how knowledge of artistic style, descriptive and elaborate information, expertise, and context all affect aesthetic experiences from art. Limiting aesthetics to rather rare experiences unnecessarily narrows the scope of a science of art.

Digital images taken by mobile phones are the most frequent class of images created today. Due to their omnipresence and the many ways they are encountered, they require a specific focus in research. However, to date, there is no systematic compilation of the various factors that may determine our evaluations of such images, and thus no explanation of how users select and identify relatively “better” or “worse” photos. Here, we propose a theoretical taxonomy of factors influencing the aesthetic appeal of (...) mobile phone photographs. Beyond addressing relatively basic/universal image characteristics, perhaps more related to fast perceptual processing of an image, we also consider factors involved in the slower re-appraisal or deepened aesthetic appreciation of an image. We span this taxonomy across specific types of picture genres commonly taken—portraits of other people, selfies, scenes and food. We also discuss the variety of goals, uses, and contextual aspects of users of mobile phone photography. As a working hypothesis, we propose that two main decisions are often made with mobile phone photographs: Users assess images at a first glance—by swiping through a stack of images—focusing on visual aspects that might be decisive to classify them from “low quality” to “acceptable” to, in rare cases, “an exceptionally beautiful picture.” Users make more deliberate decisions regarding one’s “favorite” picture or the desire to preserve or share a picture with others, which are presumably tied to aspects such as content, framing, but also culture or personality, which have largely been overlooked in empirical research on perception of photographs. In sum, the present review provides an overview of current focal areas and gaps in research and offers a working foundation for upcoming research on the perception of mobile phone photographs as well as future developments in the fields of image recording and sharing technology.

A Paramecium cell has a stereotypically patterned surface, with regularly arranged cilia, dense‐core secretory vesicles and subplasmalemmal calcium stores. Less strikingly, there is also a patterning of molecules; for instance, some ion channels are restricted to certain regions of the cell surface. This design may explain very effective and selective responses, such as that to Ca2+ upon stimulation. It enables the cell to respond to a Ca2+ signal precisely secretion (exocytosis) or by changing its ciliary activity. These responses depend on (...) the location and/or type of signal, even though these two target structures co‐exist side‐by‐side, and normally only limited overlap occurs between the different functions. Furthermore, the patterning of exocytotic sites and the possibility of synchronous exocytosis induction in the sub‐second time range have considerably facilitated analyses, and thus led to new concepts of exocytotic membrane fusion. It has been possible to dissect complicated events like overlapping Ca2+ fluxes produced from external sources and from internal stores. Since molecular genetic approaches have become available for Paramecium, many different gene products have been identified only some of which are known from “higher” eukaryotes. Although a variety of basic cellular functions are briefly addressed to demonstrate the uniqueness of this unicellular organism, this article focuses on exocytosis regulation.

In recent years the science-and-religion/spirituality/theology dialogue has flourished, but the impact on the minds of the general public, on society as a whole, has been less impressive. Also, religious believers and outspoken atheists face each other without progressing toward a common understanding. The view taken here is that achieving a more marked impact of the dialogue would be beneficial for a peaceful survival of humanity. I aim to argue the why and how of that task by analyzing three possible purposes (...) of the dialogue and their logical interdependence, suggest conceivable improvements of the quality and extent of the current efforts toward a negotiated action plan, and consider an enlargement of the circle of the actors involved. The dialogue that has been carried on between science and religion/spirituality/theology could be expanded and usefully applied to some major problems in the present world. (shrink)

Explanation and prediction play an important role in medical decision making, particularly for diagnostic and treatment decisions. For the most part, explanations as well as predictions are derived from causal knowledge and have to be made under uncertainty. In cognitive psychology, these phenomena have been approached from two directions. On the one hand, there is research on knowledge representation and inferential reasoning (Holland et al. 1986; Anderson 1990). On the other hand, there is research on heuristics and biases in judgments (...) under uncertainty (Kahneman et al. 1982; Rehm & Gadenne 1990). However, no exact models have yet been developed to describe the process that leads from a given knowledge base to judgments of probabilities, i.e., from causal knowledge about the world to subjective expressions of the uncertainty associated with explanations or predictions.

The way physics and other parts of science work can be explained in the framework of radical constructivism. However, this constructivist view itself shows that a uniquily accepted epistemology, constructivism or any other, would not be an advantage for the developmentof science. Unlike physics some parts of science successfully use constructivist concepts inside their theories. Because this is the case particularly in learning theory, constructivist ideas can help to improve physics teaching.

Wittgenstein in his later years thought about experiences of meaning and aspect change. Do such experiences matter? Or would a meaning- or aspect-blind person not lose much? Moreover, is this a matter of aesthetics or epistemology? To get a better perspective on these matters, I will introduce distinctions between certain subjective and objective aspects, namely feelings of our inner psychological states versus fine-tuned objective experiences of the outer world. It seems to me that in his discussion of meaning-blindness, Wittgenstein unhappily (...) floats between these two extremes, the subjective and the objective. I will also introduce some notions from Kant's aesthetics, to get a better understanding of the interplay between feeling and meaning. This will shed some new light on Wittgenstein's enquiry into meaning- and aspect-blindness. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:UNDERSTANDING THE DIFFERENCE OF BEING: ON THE RELATIONSHIP BETWEEN METAPHYSICS AND THEOLOGY HELMUT HOPING University of Tubingen, Germany Introduction T:HE PHILOSOPHY of the twentieth century has been o no small extent a critique of metaphysics. Admittedly, philosophical programs have been developed in which the tradition of metaphysics survives. Yet the position of metaphysics in the modern age is disputed even today-as is demonstrated by the recent controversy between (...) Jiirgen Habermas and Dieter Henrich about the possibility of metaphysics after Kant.1 Since 1 See J. Habermas, "Ruckkehr zur Metaphysik: Eine Tendenz in der deutschen Philosophie?" Merkur 439/440, 39 (1985): 898-905; "Metaphysik nach Kant," in K. Cramer et al., eds., Theorie der Subjektivitiit: Dieter Henrich zum 60. Geburtstag (Frankfurt am Main: Suhrkamp, 1978), 425-443. (Both articles are reprinted in J. Habermas, Nachmetaphysisches Denken: Philosophische Aufsiitze [Frankfurt am Main: Suhrkamp, 1988], 18-34; 267-279.) Henrich replied to Habermas's critique in the article "Was ist Metaphysik, was Moderne?: Thesen gegen Jurgen Habermas," Merkur 440, 40 (1986): 495-508 (reprinted in D. Henrich, Konzepte: Essays zur Philosophie der Zeit [Frankfurt am Main: Suhrkamp, 1987], 11-43). On the controversy between Habermas and Henrich, see V. Gerhardt, " Metaphysik und ihre Kritik: Zur Metaphysikdebatte zwischen Jurgen Habermas und Dieter Henrich," Zeitschrift fur philosophische Forschung 42 (1988) : 45-70. Habermas's notion of a " return to metaphysics " undoubtedly has a certain diagnostic value; after all, there has indeed been a recent " discovery " of metaphysics. But Habermas 's criticism of the concept and content of metaphysics-i.e., his thesis that after Kant metaphysics is impossible-not only contradicts the self-understanding of modern philosophy for which metaphysics is essential; it also fails to recognize the metaphysical implications of his own theory of communicative action. See W. C. Zimmerli, "Kommunikation und Metaphysik: Zu den Anfangsgrunden von Habermas ' ' Theorie des kommunikativen Handelns,' " in W. Oelmuller, ed., Metaphysik heute? Kolloquien zur Gegenwartsphilosophie, vol. 10 (Paderborn: SchOningh, 1987), 97-111. 189 190 HELMUT HOPING metaphysics has been indispensable for the self-understanding of philosophy in the modern age up until Hegel, this controversy cannot be reduced to the simple disjunction: either the "end of metaphysics" or the "return to metaphysics "-as Habermas has suggested. The task of philosophy today lies in a metaphysical form of thinking that remains possible even after the critique of metaphysics in Kant and Heidegger. Until recently, the current debate about metaphysics has not been adequately addressed by theology. That is surprising because metaphysics is also indispensable for theology.2 But in the light of the modern critique of metaphysics, the self-understanding of theology and its relationship to metaphysics cannot remain unchanged -just as the self-understanding of metaphysics itself cannot remain unchanged. Yet at least in the realm of Catholic theology, the traditional doctrine of the praeambula fidei has not been abandoned. The aim of the following reflections is to show that the determination of the relationship between metaphysics and theology depends upon how metaphysics understands the " difference of Being" that is given with the manifold of beings. I will introduce four different understandings of the " difference of Being": that which is found in Aquinas's metaphysics; that in Kant's transcendental philosophy; that in Heidegger's thinking of Being; and that in the metaphysics of the absolute projected by Henrich. In some concluding reflections, I will then try to draw out some implications of these understandings of the " difference of Being " for the determination of the relationship between metaphysics and theology. I. Metaphysics of God and Creation : Theological Difference (Aquinas) It is well-known that Thomas Aquinas defines metaphysics as the science of being qua being. The subject-matter that dis2 See W. Kasper, " Zustimmung zum Denken: Von der Unerlasslichkeit der Metaphysik fiir die Sache der Theologie," Tiibinger Theologische Quartalschrift 169 (1989) : 257-271. RELATIONSHIP BETWEEN METAPHYSICS & THEOLOGY 191 tinguishes metaphysics from all other sciences is the ens inquantum est ens 3 or the ens commune.4 Contrary to later concepts of metaphysics, this is not an abstract-universal, for " the term ' a being' [ens], which is applied to a thing by reason of its being [esse], designates the same thing as the term which is applied...

Die Publikation bietet einen geschichtlichen Überblick über die Auseinandersetzung bedeutender Philosophen mit dem ältesten Problem der Philosophie: dem Leib-Seele-Problem. Wenn auch philosophischen Ursprungs, reflektieren die ausgewählten Philosophen die Bezüge zu theologischen, psychologischen, psychosomatischen, naturwissenschaftlichen und medizinischen Dimensionen dieses Problems. Im Vordergrund steht dabei die Herausarbeitung aller Aspekte des Leib-Seele-Problems. So beschäftigen sich die Herausgeber dieses Bandes mit den Fragen, ob Leib und Seele wirklich verschieden oder identisch sind, wie sie aufeinander einwirken und ob die Seele nach dem Tod weiter bestehen (...) kann.

The knowledge of opinion leaders to a certain extent has always been taken for granted by communication scholars. This article investigates what opinion leaders really know. Two studies will be presented to answer the above question. Participants of the first study were assessed according to ratings on three scales of opinion leadership, personality strength and political knowledge. In the second study, respondents were assessed according to ratings of opinion leadership and political knowledge. In both studies, it was found that opinion (...) leaders can be divided into ‘informed opinion leaders’, who know a lot in their area of interest, and ‘uninformed opinion leaders’, who are ill-informed about the field they claim as theirs. In both studies ‘informed opinion leaders’ read newspapers approximately one hour longer per week than ‘uninformed opinion leaders’. (shrink)

Clahsen's claim to contribute arguments for dual mechanisms based on rule analysis and against connectionist proposals is refuted. Both types of modeling are inadequate for principled reasons.

Das Verhältnis von Natur und Idee ist für jede idealistische Philosophie ein Kernpunkt ihres Ansatzes. Hegel bestimmte die Natur als das Andere der Idee, die sich in Freiheit als Natur aus sich entläßt. In der Natur zeigen sich die logischen Strukturen verhüllt und im Abbild, z. B. die Naturgesetze und die logischen Beziehungen. Auch die Kategorie des Lebens in Hegels Logik belegt die enge Verbindung von Natur und Logik. Die Entäußerung der Idee in der Natur gehört zum Wesen der Idee (...) auf ihrem Weg zum Geist. Diese Thematik wird in acht Beiträgen von bekannten Hegelforschern unter verschiedenen Aspekten bearbeitet. Sie verstehen die Sicht Hegels als einen bedeutenden Entwurf, der die Einheit der Wirklichkeit unter dem Vorzeichen der Idee zur Geltung bringt. (shrink)

When Professor Johannes Hoffmeister died in Bonn in 1955, a unique institution was created to continue the project he had begun - the historic-critical edition of the complete works of Hegel. This institution is known as the Hegel-Archiv.
