A comparison is made between the scientific receptions of three proposed new members of the hominin phylogenetic tree: the first finds of Neanderthal Man, those of Homo erectus, and those of Homo floresiensis. In each case, the leading scientists of the moment of discovery heavily debated the finds and neglected the meaning of those finds. At least it took/will take one generation before the meaning of those finds were/will be accepted.

Wer Fichtes Programm der Wissenschaftslehre in der Ersten Einleitung betrachtet, in der er sie als Lehre des Grundes »des Systems der vom Gefühle der Nothwendigkeit begleiteten Vorstellungen« beschreibt, kann über die Verwendung des Begriffs der Notwendigkeit in 1812 nur erstaunt sein. Denn in diesem Vortrag verwendet Fichte in seinen Diskussionen mit Spinoza und Schelling, aber auch schon in 1811, den Begriff der Notwendigkeit - vielleicht bloß scheinbar - metaphysisch als bezogen auf das Absolute selbst. Die erstgenannten Bemerkungen und die weiteren (...) Bestimmungen im Rahmen der Wissenschaftslehren zeigen, daß sich Fichte zeitlebens über die Bedeutung der Modalkategorien durchwegs im klaren war. Dennoch stellt sich später folgende Frage: Wenn die Modalkategorien auf das Absolute bezogen werden, erneuert Fichte dann in seiner letzten Schaffensphase eine Metaphysik des Absoluten, oder betrachtet er diese Diskussion der vormaligen Metaphysik nur deshalb, um in einer negativen Folie seine eigene Darstellung der Wissenschaftslehre als Sicherscheinung des Absoluten klarzumachen?

A relaçáo entre conflitos morais e consistência moral estabelecida neste trabalho foi realizada graças à natureza de alguns tipos de conflitos morais, a saber: os (...) insolúveis ou genuínos - que seráo explicados ao longo do trabalho. Conflitos desse tipo sáo capazes de causar inconsistências nas normas de certos sistemas morais, como por exemplo, os preponderantemente racionalistas. Partindo desse problema, os autores que se dispõe a trabalhar este tema demonstram opiniões divididas: alguns optam por defender a genuinidade dos conflitos morais insolúveis e consideram as eventuais inconsistências na teoria moral como secundárias, enquanto outros optam por salvaguardar a lógica do pensamento e das teorias morais, negando os conflitos morais insolúveis. Este artigo busca esboçar tal “divisáo” entre os autores, ao explorar brevemente as argumentações de ambas as partes. Por fim, fica demonstrado que uma discussáo sobre consistência e conflitos morais precisa considerar tanto a esfera metaética quanto a esfera normativa da ética. (shrink)

The knower paradox states that the statement ‘We know that this statement is false’ leads to inconsistency. This article presents a fresh look at this paradox and some well-known solutions from the literature. Paul Égré discusses three possible solutions that modal provability logic provides for the paradox by surveying and comparing three different provability interpretations of modality, originally described by Skyrms, Anderson, and Solovay. In this article, some background is explained to clarify Égré’s solutions, all three of which hinge on (...) intricacies of provability logic and its arithmetical interpretations. To check whether Égré’s solutions are satisfactory, we use the criteria for solutions to paradoxes defined by Susan Haack and we propose some refinements of them. This article aims to describe to what extent the knower paradox can be solved using provability logic and to what extent the solutions proposed in the literature satisfy Haack’s criteria. Finally, the article offers some reflections on the relation between knowledge, proof, and provability, as inspired by the knower paradox and its solutions. (shrink)

Signed utterances are densely packed with pointing signs, reaching a frequency of one in six signs in spontaneous conversations (de Vos, 2012; Johnston, 2013a; Morford & MacFarlane, 2003). These pointing signs attain a wide range of functions and are formally highly diversified. Based on corpus analysis of spontaneous pointing signs in Kata Kolok, a rural signing variety of Bali, this paper argues that the full meaning potentials of pointing signs come about through the integration of a varied set of linguistic (...) and extralinguistic cues. Taking this hybrid nature of pointing phenomena into account, it is argued that pointing signs may become an intrinsic aspect of sign language grammars through two mechanisms: morphemization and syntactic integration. Although not entailed in this research, this approach could implicate that some highly systematized pointing systems of speaking communities may to a degree be grammatical as well. (shrink)

Background In the ethical and clinical literature, cases of parents who want treatment for their child to be withdrawn against the views of the medical team have not received much attention. Yet resolution of such conflicts demands much effort of both the medical team and parents. Objective To discuss who can best protect a child9s interests, which often becomes a central issue, putting considerable pressure on mutual trust and partnership. Methods We describe the case of a 3-year-old boy with acquired (...) brain damage due to autoimmune-mediated encephalitis whose parents wanted to stop treatment. By comparing this case with relevant literature, we systematically explored the pros and cons of sharing end-of-life decisions with parents in cases where treatment is considered futile by parents and not (yet) by physicians. Conclusions Sharing end-of-life decisions with parents is a more important duty for physicians than protecting parents from guilt or doubt. Moreover, a request from parents on behalf of their child to discontinue treatment is, and should be, hard to over-rule in cases with significant prognostic uncertainty and/or in cases with divergent opinions within the medical team.
