With Charles Sanders Peirce's semiotical theory two different kinds of creative metaphorical reasoning in science can be identified. The building of remainder metaphors is especially important for creating new scientific models. We show that the conveyor belt metaphor provides an excellent example for Peirce's theory. The conveyor belt metaphor has recently been invented in order to describe the oceanic transport system. The paradigm of the oceanic conveyor belt strongly influenced the geoscience community and the climate change discussion.

Despite decades of research, morphogenesis along the various body axes remains one of the major mysteries in developmental biology. A milestone in the field was the realisation that a set of closely related regulators, called Hox genes, specifies the identity of body segments along the anterior–posterior (AP) axis in most animals. Hox genes have been highly conserved throughout metazoan evolution and code for homeodomain‐containing transcription factors. Thus, they exert their function mainly through activation or repression of downstream genes. However, while (...) much is known about Hox gene structure and molecular function, only a few target genes have been identified and studied in detail. Our knowledge of Hox downstream genes is therefore far from complete and consequently Hox‐controlled morphogenesis is still poorly understood. Genome‐wide approaches have facilitated the identification of large numbers of Hox downstream genes both in Drosophila and vertebrates, and represent a crucial step towards a comprehensive understanding of how Hox proteins drive morphological diversification. In this review, we focus on the role of Hox genes in shaping segmental morphologies along the AP axis in Drosophila, discuss some of the conclusions drawn from analyses of large target gene sets and highlight methods that could be used to gain a more thorough understanding of Hox molecular function. In addition, the mechanisms of Hox target gene regulation are considered with special emphasis on recent findings and their implications for Hox protein specificity in the context of the whole organism.

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.

In connection with research on humans, the term “vulnerability” is only appropriate to identify the special need for protection of certain sections of the population and individuals, if this term refers to the additional risk of certain groups of subjects. Authors who focus on the additional risk suffering of a subject group when defining vulnerability succeed in considering the specific worthiness of protection in a context-sensitive way. The attempt to define the risk–benefit assessment for vulnerable subject groups on a binding (...) basis faces considerable difficulties. This assessment depends both on the research situation and on the test subject. The normative aspect of this decision could be solved by referring to Rawl’s decision model of an original position. In cases where there is no benefit for the subject, arguments in the discussion of the risks and benefits that are based on a “group or overall benefit” and an “objective interest,” cannot be fully sustained.

Contingent valuation surveys have tended to yield results that seem to go contrary to what is standardly seen as 'rational choice'. We argue that some of the inconsistencies arise because bids for public environmental goods in contingent valuation surveys are often motivated by moral considerations and ethical beliefs. We analyse the expected results of CV surveys given the existence of such ethical motivations, including the valuation of actions as well as states. It is found that we cannot expect bids made (...) on this basis to reveal preferences which obey the rules commonly assumed in the theory of consumer choice. The two standard reactions to these anomalies have been to attack the validity of the method, or to urge greater rigour in survey design and application. By contrast, we conclude that the usefulness of the method for evaluating options concerning environmental public goods depends critically on the problem definition. The method should be used for the direct evaluation of realistic policy packages, rather than to try to extract abstract values for invaluable goods. The conclusion accords with current trends, including the move towards the use of deliberative methodologies. (shrink)

Modal dependence logic was introduced recently by Väänänen. It enhances the basic modal language by an operator = (). For propositional variables p 1, . . . , p n , = (p 1, . . . , p n-1, p n ) intuitively states that the value of p n is determined by those of p 1, . . . , p n-1. Sevenster (J. Logic and Computation, 2009) showed that satisfiability for modal dependence logic is complete for nondeterministic (...) exponential time.In this paper we consider fragments of modal dependence logic obtained by restricting the set of allowed propositional connectives. We show that satisfiability for poor man’s dependence logic, the language consisting of formulas built from literals and dependence atoms using ${\wedge, \square, \lozenge}$ (i. e., disallowing disjunction), remains NEXPTIME-complete. If we only allow monotone formulas (without negation, but with disjunction), the complexity drops to PSPACE-completeness.We also extend Väänänen’s language by allowing classical disjunction besides dependence disjunction and show that the satisfiability problem remains NEXPTIME-complete. If we then disallow both negation and dependence disjunction, satisfiability is complete for the second level of the polynomial hierarchy. Additionally we consider the restriction of modal dependence logic where the length of each single dependence atom is bounded by a number that is fixed for the whole logic. We show that the satisfiability problem for this bounded arity dependence logic is PSPACE-complete and that the complexity drops to the third level of the polynomial hierarchy if we then disallow disjunction.In this way we completely classify the computational complexity of the satisfiability problem for all restrictions of propositional and dependence operators considered by Väänänen and Sevenster.

Information can be public among a group. Whether or not information is public matters, for example, for accounts of interdependent rational choice, of communication, and of joint intention. A standard analysis of public information identifies it with (some variant of) common belief. The latter notion is stipulatively defined as an infinite conjunction: for p to be commonly believed is for it to believed by all members of a group, for all members to believe that all members believe it, and so (...) forth. This analysis is often presupposed without much argument in philosophy. Theoretical entrenchment or intuitions about cases might give some traction on the question, but give little insight about why the identification holds, if it does. The strategy of this paper is to characterize a practical-normative role for information being public, and show that the only things that play that role are (variants of) common belief as stipulatively characterized. In more detail: a functional role for “taking a proposition for granted” in non-isolated decision making is characterized. I then present some minimal conditions under which such an attitude is correctly held. The key assumption links this attitude to beliefs about what is public. From minimal a priori principles, we can argue that a proposition being public among a group entails common commitment to believe among that group. Later sections explore partial converses to this result, the factivity of publicity and publicity from the perspective of outsiders to the group, and objections to the aprioricity of the result deriving from a posteriori existential presuppositions.

„Das Leben zu erkennen“ (II,5,112) bestimmt Fichte als Gegenstand der „Wissenschaftslehre“ (1794 ff.). Die Aufgabe der Philosophie besteht für ihn nicht darin, „durch die Kraft (der) Syllogismen neue Objekte des natürlichen Denkens“ (II,5,112) zu erschaffen. Er gewichtet seine Philosophie dergestalt, daß sie „das Leben, das System der Gefühle und das Begehren zum Höchsten (macht) und... der Erkenntnis überall nur das Zusehen (läßt)“ (II,5,137). Die herausragende Stellung des Gefühls besteht darin, daß es einerseits als begrifflich explizierbarer Teilaspekt der Reflexionen über die (...) Grundbedingungen der unterschiedlichen Bewußtseins- bwz. Lebensformen des Menschen selbst Bestandteil der „Wissenschaftslehre“ ist und daß es andererseits zugleich als die ausgezeichnete Weise der Selbstmanifestation dieser Lebensformen zu bestimmen ist, deren Genese in der „Wissenschaftslehre“ rekonstruiert wird. Fichte entwickelt im System der „Wissenschaftslehre“ eine weitreichende und complex strukturierte Theorie des Gefühls, die die Bereiche des theoretischen und praktischen, sinnlichen, intellektuellen und intelligiblen Lebens umfaßt. In einem systematisch angelegten Untersuchungsstrang werden Genese, Stellenwert und Funktion des Gefühls in der „Wissenschaftslehre“ und ihren Teildisziplinen entwickelt. In historischer Hinsicht wird Fichtes Lehre vom Gefühl im Kontext der zeitgenössischen Diskussion (Kant, Jacobi u.a.) erörtert. Systematische und historische Zielsetzungen werden parallel aus einer entwicklungsgeschichtlichen Perspektive entfaltet. Im Ausgang von den Jugendschriften bis zur „Wissenschaftslehre 1801“ wird der Begriff des Gefühls in seinen pädagogischen, erkenntnistheoretischen, moralischen und religiösen Bedeutungen untersucht.

Spatial, physical, and semantic magnitude dimensions can influence action decisions in human cognitive processing and interact with each other. For example, in the SNARC effect, semantic numerical magnitude facilitates left-hand or right-hand responding dependent on the small or large magnitude of number symbols. SNARC-like interactions of numerical magnitudes with the radial spatial dimension (depth) were postulated from early on. Usually, the SNARC effect in any direction is investigated using fronto-parallel computer monitors for presentation of stimuli. In such 2D setups, however, (...) the metaphorical and literal interpretation of the radial depth axis with seemingly close / far stimuli or responses are not distinct. Hence, it is difficult to draw clear conclusions with respect to the contribution of different spatial mappings to the SNARC effect. In order to disentangle the different mappings in a natural way, we studied parametrical interactions between semantic numerical magnitude, horizontal directional responses, and perceptual distance by means of stereoscopic depth in an immersive virtual reality (VR). Two VR experiments show horizontal SNARC effects across all spatial displacements in traditional latency measures and kinematic response parameters. No indications of a SNARC effect along the depth axis, as it would be predicted by a direct mapping account, were observed, but the results show a non-linear relationship between horizontal SNARC slopes and physical distance. Steepest SNARC slopes were observed for digits presented close to the hands. We conclude that spatial-numerical processing is susceptible to effector-based processes but relatively resilient to task-irrelevant variations of radial-spatial magnitudes. (shrink)

The essay is a critical revision of various of Marx’s approaches in his analysis of capitalism in “Das Kapital”. One can distinguish immanent, normative critiques from transcendental and objectivistic ones. The review of the normative standards used in each case leads to the questions of how Marx determined and used the relationships of justice and law and the capitalist mode of production. Orthodox Marxist views (most recently C. Menke) claim that Marx did not criticise capital as unjust and understood the (...) law of capital only as private law that stabilised domination. Against this, it is shown that he certainly bases his “critical presentation” on an (almost Kantian) constitutional (“rechtsstaatliches”) concept of private law and public law. Thus the “popular prejudice” of “human equality”, defined by Marx as an epochal and systematic condition of the capitalist exchange of goods, becomes apparent as a covert reference to the historical (America, French Revolution),public-lawdeclarations of human rights. And in the chapter “Struggle for the length of the working day” Marx presents the decisions of this dispute between “equal rights” first and foremost in the systematic historical actions of the constitutional powers (legislature, executive and judiciary). At the same time, however, he attempts to ironise and defame this public-law and deliberative, democratic dispute and then to misinterpret it as a violent “civil war”. Because Marx in his further presentation ignores this legal-democratic dispute, including a potential human-rights critique and (possible!) future regulation of capitalism, focussing instead on objectivist concepts of history and development, he can only insufficiently grasp the still challenging relationship between democracy and capitalism.

Traditionally, empathy is conceived of as a cognitive function that governs how people think during social interactions, and is considered as largely impervious to change. However, developments in psychology and neuroscience show that empathy is grounded in neural substrates of emotionally communicative behaviour and so is learned through imitation and other forms of cultural learning. This also means that abnormal patterns of empathic function can develop through adverse life experiences, or that empathy may fail to develop in young people with (...) neurodevelopmental disorders. Nevertheless, by focussing on empathy as a quality of social interaction and affective expression in the here and now, and by appreciating that it is as a special form of sensorimotor skill, pathways to training and fostering better development of empathy can be identified.

Donald Green and Ian Shapiro argue that rational choice scholarship in political science is excessively theory?driven: too few of its theoretical insights have been subjected to serious empirical scrutiny and survived. But rational choice theorizing has the potential to identify and correct logical inconsistencies and slippages. It is thus valuable even if the resulting theories are not tested empirically. When Green and Shapiro's argument concerning collective dilemmas and free riding is formalized, it turns out to be deeply flawed and in (...) many respects outright false. Their mistake is common enough: they misclassify a variety of collective dilemmas as prisoner's dilemmas. Because they misunderstand the theory of rational choice, Green and Shapiro allege that it is refuted by empirical findings that, in fact, support it. (shrink)
