The first part of the studies contains a fundamental work on "Helmuth Plessner. Philosoph und Soziologe-Wissenschaft als Beruf in der Endzeit des bürgerlichen Humanismus", on which Christian von Ferber wrote until old age and whose discussion is still pending. In the second part of the studies, von Ferber describes his career in the post-war period under the influence and in the circles of Helmuth Plessner and other teachers, up to becoming a professor of sociology. He followed three orientations: (...) Science is more than the acquisition of methodological and theoretical competence. Scepticism is appropriate towards statements that cannot relate to primary reality, and science is related to the values of human life. Funda-mental reflections on the freedom-securing character of sociology and on central questions of health policy and social medicine illuminate Christian von Ferber's life's work and the topicality of his questions.

The theory of Gestalt qualities arose from the attempt to explain how a melody is distinct from the collection of the tones which it comprehends. In this essay from 1890 Christian von Ehrenfels coined the term 'Gestaltqualität' to capture the idea of a pattern which is comprehensible in a single experience. This idea can be applied not only to melodies and other occurrent patterns, but also to continuant patterns such as shapes and colour arrays such as the array of a (...) chess board. Ehrenfel's essay gave birth to the Gestalt movement in psychology. (shrink)

Von Hippel & Trivers reason that the potential benefits of successfully deceiving others provide a basis for the evolution of self-deception. However, as self-deceptive processes themselves provide considerable adaptive value to an individual, self-deception may have evolved as an end in itself, rather than as the means to an end of improving other-deception.

The allegedly alternative theories of Phyletic Gradualism and Punctuated Equilibria are examined as regards the nature of their differences. The explanatory value of both models is determined by establishing their actual connection with reality. It is concluded that they are to be considered complementary rather than mutually exclusive at all levels of infraspecific, specific, and supraspecific evolution. So, in order to be described comprehensively, the pathways of evolution require at least two distinct models, each based on a discrete range of (...) real phenomena.

Many attempts have been made at supporting either one of the allegedly complementary divergence models Phyletic Gradualism and Punctuated Equilibria by patterns found in specific fossil sequences. However, assessing each model's connection with reality via such “individual case histories” appears not to constitute a relevant approach. Instead, in order to correctly establish the possible merits of both concepts, the claims of each have to be verified against general evolutionary theory. This is being pointed out herein by analyzing cladogenesis at the (...) specific level as an example.

Human moral judgement may have evolved to maximize the individual's welfare given parochial culturally constructed moral systems. If so, then moral condemnation should be more severe when transgressions are recent and local, and should be sensitive to the pronouncements of authority figures (who are often arbiters of moral norms), as the fitness pay-offs of moral disapproval will primarily derive from the ramifications of condemning actions that occur within the immediate social arena. Correspondingly, moral transgressions should be viewed as less objectionable (...) if they occur in other places or times, or if local authorities deem them acceptable. These predictions contrast markedly with those derived from prevailing non-evolutionary perspectives on moral judgement. Both classes of theories predict purportedly species-typical patterns, yet to our knowledge, no study to date has investigated moral judgement across a diverse set of societies, including a range of small-scale communities that differ substantially from large highly urbanized nations. We tested these predictions in five small-scale societies and two large-scale societies, finding substantial evidence of moral parochialism and contextual contingency in adults' moral judgements. Results reveal an overarching pattern in which moral condemnation reflects a concern with immediate local considerations, a pattern consistent with a variety of evolutionary accounts of moral judgement.

The term “synthetic biology” is a popular label of an emerging biotechnological field with strong claims to robustness, modularity, and controlled construction, finally enabling the creation of new organisms. Although the research community is heterogeneous, it advocates a common denominator that seems to define this field: the principles of rational engineering. However, it still remains unclear to what extent rational engineering—rather than “tinkering” or the usage of random based or non-rational processes—actually constitutes the basis for the techniques of synthetic biology. (...) In this article, we present the results of a quantitative bibliometric analysis of the realized extent of rational engineering in synthetic biology. In our analysis, we examine three issues: (1) We evaluate whether work at three levels of synthetic biology (parts, devices, and systems) is consistent with the principles of rational engineering. (2) We estimate the extent of rational engineering in synthetic biology laboratory practice by an evaluation of publications in synthetic biology. (3) We examine the methodological specialization in rational engineering of authors in synthetic biology. Our analysis demonstrates that rational engineering is prevalent in about half of the articles related to synthetic biology. Interestingly, in recent years the relative number of respective publications has decreased. Despite its prominent role among the claims of synthetic biology, rational engineering has not yet entirely replaced biotechnological methods based on “tinkering” and non-rational principles.

Cell‐based therapies for degenerative diseases of the musculature remain on the verge of feasibility. Myogenic cells are relatively abundant, accessible, and typically harbor significant proliferative potential ex vivo. However, their use for therapeutic intervention is limited due to several critical aspects of their complex biology. Recent insights based on mouse models have advanced our understanding of the molecular mechanisms controlling the function of myogenic progenitors significantly. Moreover, the discovery of atypical myogenic cell types with the ability to cross the blood‐muscle (...) barrier has opened exciting new therapeutic avenues. In this paper, we outline the major problems that are currently associated with the manipulation of myogenic cells and discuss promising strategies to overcome these obstacles. (shrink)

Dance provides natural conditions for studying relationships between coordination patterns and human experience. von Zimmermann and colleagues investigate whether relatively simple or more complex forms of movement coordination are related to pro‐social experiences during group dance. They find that pro‐social experience depends on the degree to which movement patterns are distributed and diversified, but not the degree to which movement patterns are simply unitary.

This bilingual volume—English and German on facing pages—brings together the writings Wittgenstein composed during his stay in Dublin between October 1948 and March 1949, one of his most fruitful periods. He later drew more than half of his remarks for Part II of _Philosophical Investigations_ from this Dublin manuscript. A direct continuation of the writing that makes up the two volumes of _Remarks on the Philosophy of Psychology,_ this collection offers scholars a glimpse of Wittgenstein's preliminary thinking on one of (...) his most important works. G. H. von Wright and Heikki Nyman both teach at the University of Helsinki. (shrink)

This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It is concluded (...) that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination‐shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus‐response relationships, not with the acquisition of mediating rules such as conceived in (neo‐)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures. (shrink)
