The dignity of human embryos. On the moral relevance of potentiality and numerical identity. -.

Würdeschutz und Lebensschutz werden insbesondere in der angewandten Ethik regelmäßig als fundamentale Beurteilungsprinzipien herangezogen. Das genaue Verhältnis dieser beiden normativen Aspekte erweist sich allerdings als unsicher: Oftmals scheinen Würdeverletzungen gerade in einer unberechtigten Beeinträchtigung von anderen Rechtsgütern wie Leben oder Gesundheit, auch Eigentum oder Ansehen zu bestehen. Darüber hinaus aber mag es Würdeverletzungen geben, die sich nicht auf eine verfehlte Missachtung solcher anderweitiger Rechtsbelange herunterbrechen lassen, sondern eigenständige Formen der Demütigung und Erniedrigung, der Ausnutzung und Verwendung bezeichnen. Der vorliegende Beitrag (...) geht dieser Frage namentlich mit Blick auf die Forschung an Menschen, an Tieren und an Embryonen nach. Dabei liefert eine bestimmte Fallkonstellation in der Debatte um die Embryonenforschung einen starken Beleg dafür, dass Würde in der Tat zuweilen einen originären Schutzbereich markiert, der unabhängig von Fragen des Umgangs mit Leben oder sonstigen elementareren Rechtsgütern ist.

ZusammenfassungDie öffentliche Wahrnehmung der Forschung mit extrakorporalen Embryonen bildet den Kern des vorliegenden Beitrags. Hierzu wurden über 400 Personen schriftlich befragt. Die Art der Embryonengewinnung (künstliche Erzeugung vs. überzählige Embryonen) wird als bedeutsam für die Bewertung der Forschung angesehen. Mehrheitlich besteht der Wunsch nach rechtlich klaren Grenzen. Die größte Ambivalenz zeigt sich hinsichtlich der Frage nach einer gesetzlichen Erlaubnis der Embryonenforschung. Umgekehrt hat die Bevölkerung eine eindeutigere Meinung zum Verbot von Embryonenforschung und zur Einführung strikter rechtlicher Regelungen. Die (...) Wahl der Mittelkategorie bei der Untersuchung der Einstellung ist durch das Ausmaß der Ambivalenz mitbestimmt. Es konnte nachgewiesen werden, dass Laien das Dilemma der Embryonenforschung ähnlich bewerten wie Experten. Der Wunsch nach einer Freigabe der Forschung mit Embryonen besteht bei einer Teilgruppe, jedoch ist dieser Wunsch von einem hohen Ausmaß an Ambivalenz begleitet. (shrink)

Das Potenzialitätsargument (PA) ist das wohl wichtigste Argument der Gegner der verbrauchenden Embryonenforschung und des Schwangerschaftsabbruchs. Weil schon der frühe Embryo eine potenzielle Person sei, so das Argument, besitze er bereits den moralischen Status einer Person. Mit der Möglichkeit, aus differenzierten somatischen Zellen „ethisch unproblematische“ induzierte pluripotente Stammzellen (iPS-Zellen) zu gewinnen, schien diese PA-Problematik zumindest für die Forschung umgangen. Indessen zeigen neuere wissenschaftliche Erkenntnisse, dass auch aus pluripotenten Zellen neue Organismen erwachsen können. Der Beitrag argumentiert dafür, dass nach der Logik (...) von PA nicht nur iPS-Zellen, sondern auch die somatischen Zellen, aus denen diese entstehen, als potenzielle Personen mit Würde und Lebensrecht anzusehen wären. Aufgrund dieser Implikationen ist PA auch nicht als Argument für ein Lebensrecht von Embryonen geeignet. (shrink)

Moral behaviour, based on social norms, is commonly regarded as a hallmark of humans. Hitherto, humans are perceived to be the only species possessing social norms and to engage in moral behaviour. There is anecdotal evidence suggesting their presence in chimpanzees, but systematic studies are lacking. Here, we examine the evolution of human social norms and their underlying psychological mechanisms. For this, we distinguish between conventions, cultural social norms and universal social norms. We aim at exploring whether chimpanzees possess evolutionary (...) precursors of universal social norms seen in humans. Chimpanzees exhibit important preconditions for their presence and enforcement: tolerant societies, well-developed social-cognitive skills and empathetic competence. Here, we develop a theoretical framework for recognizing different functional levels of social norms and distinguish them from mere statistical behavioural regularities. Quasi social norms are found where animals behave functionally moral without having moral emotions. In proto social norms, moral emotions might be present but cannot be collectivized due to the absence of a uniquely human psychological trait, i.e. shared intentionality. Human social norms, whether they are universal or cultural, involve moral emotions and are collectivized. We will discuss behaviours in chimpanzees that represent potential evolutionary precursors of human universal social norms, with special focus on social interactions involving infants. We argue that chimpanzee infants occupy a special status within their communities and propose that tolerance towards them might represent a proto social norm. Finally, we discuss possible ways to test this theoretical framework. (shrink)

After a general remark about Armstrong’s conception of ontology, I raise objections against this view and defend an alternative account of the connection between particulars and their properties, involving a kind of ontological dependence which is different from Armstrong’s necessary connection between particulars and their properties.

Recently Ekman gave a derivation in natural deduction such that it either contains a substantial redundant part or else is not normal. It is shown that this problem is caused by a non-normality inherent in the usual modus ponens rule.

1807 konstatiert Hegels "Phänomenologie des Geistes" das Ende der Geschichte. 200 Jahre später scheint es Zeit für eine Bilanz: Wie verhält sich eine von technologischen und medialen Zwängen geprägte Demokratie zu dem von Hegel avisierten System der Freiheit? Als eine Geschichte der vollendeten Geschichte geht dies Buch einer Dialektik der Freiheit nach, die in der Nachfolge der Französischen Revolution im Namen von Gleichheit und Brüderlichkeit Totalität beansprucht. In der Durchsetzung dieses Anspruchs werden Wesenszüge der totalitären Systeme, der Technikfetischismus des Kommunismus (...) und die Propaganda des Faschismus, als Teil einer Entwicklung verständlich, an deren Ende die Logik des Sachzwangs und das Diktat medialer Öffentlichkeit stehen. Sollte sich Freiheit somit gerade dort vollenden, wo - jenseits der Geschichte - mehr denn je passiert, ohne dass sich noch Wesentliches ereignet? (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Political AuthorityA Christian PerspectiveMichael von BrückGeneral Reflection: Apocalyptic and Utopian Models of Progress and ReligionEuropean tradition of thought is shaped by two different mythical imaginations of time structure: apocalyptic thought and the concept of utopia.Jewish apocalyptical thinking culminated in the expectation that God would finally complete the processes of history at the end of time. In conjunction with Iranian dualism this expectation was interpreted metaphysically: After the collapse of (...) the existing order God would create a messianic kingdom of peace and justice, that is, a kingdom under the direct rule of God. This was not “political progress” in the modern sense of the term, for the subject of these final events was God himself or God alone. Human beings might participate in accelerating or slowing down these divine actions by lawful or unlawful behavior—measured according to the Mosaic Law, but human historical acting itself would not lead to a betterment in this sense. Nevertheless, this form of thought gave history a direction, and this is what inspired later Jewish and Christian intentionality. Early Christianity was shaped by the expectation of the coming end of time in the immediate future; however, at the same time it added a remarkable tension to the traditional apocalyptic idea: the tension of fulfillment of time, which had happened already in the advent of Jesus as the Christ (messiah) and an expectation of the imminent completion of time (the return of Christ, which would finally end history and start the new kingdom). Since the second century ad this myth of future time became ontologized or platonized—that is, the future was transferred into an “other world.” This means that the new quality would not be a dimension of the future (only) but graspable in the ecclesiastical mediation of the sacraments. The eucharist was the pharmakon athanasias (medicine of immortality). At the same time there was a mystical dimension that holds that in a specific spiritual experience this dimension might be experienced by any person who would be prepared to receive it as divine grace. The paradigm of early Christianity failed: Christ did not return. There was no new kingdom that would have ended known history. In order to cope with this disappointment, two forms of life emerged that shaped the [End Page 159] spirit of Christianity throughout the Middle Ages, so to speak, until the end of the eighteenth century: ecclesiastical mediation of the saving reality and mystical participation in a transtemporal Beyondness.Utopia develops on the basis of difference between imagination and reality. At least structurally utopian thinking can be found in all cultures; usually it is expressed in the power of myths. This marks a difference between utopia and apocalyptics. There are three different types of utopian thinking: spatial, temporal, and in terms of different states of consciousness. Spatial utopia expects the final accomplishment or climax of history, that is, the essence of hope, in spatial terms, in different regions of the world, faraway, behind oceans or mountains (Atlantis, the country flowing with milk and honey, El Dorado, Shambhala, the islands of the blessed, etc.). These spaces lost their power of inspiring imagination because there are no more white spots on the map, and that is why this utopia had to emigrate into extraterrestrial spaces of the universe (the contemporary myths of ET, Star Wars, etc.)Temporal utopia transfers the field of expectation to the beginning of the world (paradise, Golden Age) or to the end of history (millennialistic thought, communistic utopia). These temporal expectations lost their power of inspiring imagination because the fulfillment was heralded time and again but never happened.Utopia in terms of a different state of consciousness transfers the catastrophe (the turning point of time and history) into the consciousness of human beings (the prophets of Israel, Buddha, Jesus, in a certain way Confucius, modern New Age movements, etc.). An individual or even collective awakening of consciousness in humans would transform the world from within into a new paradise. The credibility of this model is challenged by the actual suffering in the world, which does not seem to diminish.In actual history these three types occur in mixed forms. The Western idea of...

We challenge the idea that a cognitive perspective on therapeutic change concerns only memory processes. We argue that inclusion of impairments in more generative cognitive processes is necessary for complete understanding of cases such as depression. In such cases what is identified in the target article as an “integrative memory structure” is crucially supported by processes of mental model construction.

El resurgimiento de la educación tradicional en los Estados Unidos ha generado un intenso debate en la esfera pública. Este artículo examina el debate discursivo que rodea este fenómeno. A medida que las críticas hacia los enfoques educativos progresistas se intensifican, defensores de la educación tradicional argumentan a favor de un retorno a métodos pedagógicos más tradicionales. Este resumen destaca el papel de la esfera pública como espacio de conflicto y negociación de ideas en torno a la educación. Al explorar (...) las perspectivas y los argumentos en disputa, el artículo busca arrojar luz sobre el resurgimiento de la educación tradicional y su impacto en el sistema educativo de los Estados Unidos.

Ramsey (1997) argues that connectionist representations 'do not earn their explanatory keep'. The aim of this paper is to examine the argument Ramsey gives to support that conclusion. In doing so, I identify two kinds of explanatory need—need relative to a possible explanation and need relative to a true explanation and argue that internal representations are not needed for either connectionist or nonconnectionist possible explanations but that it is quite likely that they are needed for true explanations. However, to show (...) that the latter is the case requires more than a consideration of the form of explanation involved. (shrink)

A satisfactory normative theory of acceptable risk would be useful in resolving current disputes over government safety regulation of the workplace, consumer products, and technology. Alan Gewirth has attempted to develop such a theory, arguing from the individual's right not to be harmed by the risk-imposing activities of others. His theory is analyzed in detail, and the difficulties faced by such rights-based (deontological) approaches are pointed out. It is argued that a satisfactory theory will not be of a simple rights-based (...) form. Reason is also given for doubting that it will be of a simple utilitarian form. (shrink)

A Hobbesian Model. If ever possible the modelling of the abstract pattern of the item of a philosophical theory belongs, alas!, to its interpretation. In the case of the Hobbesian theory of the natural right and the natural laws (Lev c. XIV, XV) the mathematics of the covenant-model and of its interpretation by an model of preferences and utilities is a neglect task till now. Its performance shows certain shortcomings of the Hobbesian theory.

"Agreement" is the key notion in Wittgenstein's explanation of the possibility of public language. Agreement in judgements constitutes the justification for asserting agreement in definitions. The determinates of rules are empirical; rules as determinables are transcendental. Rules are on the limit of public language, and not within it. Wittgenstein's skeptical solutions to skepticism about language and about the given are transcendentalistic. His skeptical solutions in other areas are conventionalistic. Skepticism about mental phenomena is not solved because of a systematic rule-gap (...) for the application of non-dispositional psychological concepts. (shrink)

The existence of objective knowledge and the possibility of communicating it by means of language have traditionally been taken for granted by educators. Recent developments in the philosophy of science and the historical study of scientific accomplishments have deprived these presuppositions of their former plausibility. Sooner or later, this must have an effect on the teaching of science. In this paper I am presenting a brief outline of an alternative theory of knowing that takes into account the thinking organism's cognitive (...) isolation from 'reality'. This orientation was proposed by Vico at the beginning of the 18th century, disregarded for two hundred years, and then propounded independently by Piaget as a developmentally grounded constructivist epistemology. The paper focuses specifically on the adaptive function of cognition, Piaget's scheme theory, the process of communication, and the subjective perspective on social interaction. In the concluding section it then suggests some of the consequences the shift of epistemological presuppositions might have for the practice of teaching. (shrink)
