Wille und Willensfreiheit sind ein heißes Thema, in der Gehirnforschung ebenso wie in der Philosophie. Wenn der Wille eine Folge biologischer Gehirnfunktionen ist und naturwissenschaftlich beschrieben werden kann, wie muss dann die Frage der ethischen Verantwortung des Einzelnen beantwortet werden? Für Wolfgang Seidel gehören biologisch bedingte Veränderungen auch des Gehirns zu den konkreten Erfahrungen aus der medizinischen Forschung und Praxis - wie auch die Erfahrung, dass nicht alle physiologischen Auswirkungen auf den einzelnen Menschen mit den Mitteln naturwissenschaftlichen Vorgehens (...) kausal absehbar sind. Sein Buch ist eine Kritik an dem alleinigen Erklärungsanspruch eines naturwissenschaftlichen Determinismus, der alles Denken und Verhalten in allen Details kausal aus der Gehirnforschung ableiten will. Seidels spannender alltagsphilosophischer Essay lädt zum entspannten Nachdenken über die Gehirnmechanismen und bewusste Entscheidungsfreiheit ein - wobei wir nebenbei erleben können, dass es letztlich keinen Unterschied macht, ob unser alltägliches Erleben des eigenen Wollens eine Illusion oder freier Wille ist - und dass unser Gehirn auch ethisch gut funktioniert.

Magnetism in meta-semantics is the view that the meaning of our words is determined in part by their use and in part by the objective naturalness of candidate meanings. This hypothesis is commonly attributed to David Lewis, and has been put to philosophical work by Brian Weatherson, Ted Sider and others. I argue that there is no evidence that Lewis ever endorsed the view, and that his actual account of language reveals good reasons against it.

Signal-detection methodology may be used to disentangle sensory from judgmental effects when analyzing sex differences in pain. An illustrative example is given by reanalyzing a published category-scaling experiment in terms of detection-theory indices. As a result, the apparent sex difference is recast in terms of a judgmental bias. [berkley].

The article attempts to portray architecture as a spatial medium and to analyse the processing and storage of information, objects and persons. In doing so, architectural space becomes not only the effect of these medial operations, but it also forms and materializes these processes at the same time. Openings are characterized as fundamental elements of architectural media. Also, in this regard, such classic elements as doors and windows in the sense of a room perceived as a perforated membrane, acquire a (...) new medial quality. (shrink)

The latest volume in the critically acclaimed and highly cited Attention and Performance series presents state of the art research from leading scientists in cognitive psychology and cognitive neuroscience describing the approaches being taken to understanding the mechanisms that allow us to negotiate and respond to the world around us.

In this paper it is argued that the _Physical Monadology of 1756 has to be seen as an attempt to evade the same paradox as the one given in the second antinomy of the _Critique of Pure Reason. Since this attempt presupposes the claim that space rests upon relations between substances, it contradicts the thesis that it is a mere form of intuition, presented by Kant in his dissertation of 1770. Therefore, at least since 1770 the paradox of the divisibility (...) of matter rose up again so that Kant had to deal with it once again in his first _Critique. Remarkably, his key to solve the second antinomy is the same which ruled out his earlier solution of 1756 and gave rise to the paradox again, i.e., the ideality of space and time. But, contrary to the dissertation, in the _Critique it is substituted by the doctrine that our knowledge of objects depends on and is restricted to intuitively given objects and this is crucial to the solution of the second antinomy. Finally, it will be shown how Kant deals with the problem of the divisibility of matter in the _Metaphysical Foundations of Natural Science. (shrink)

In “Lectio 55” of his Notule libri Priorum, Robert Kilwardby discussed various objections that had been raised against Aristotle’s Theses. The first thesis, AT1, says that no proposition q is implied both by a proposition p and by its negation, ∼p. AT2 says that no proposition p is implied by its own negation. In Prior Analytics, Aristotle had shown that AT2 entails AT1, and he argued that the assumption of a proposition p such that (∼p → p) would be “absurd”. (...) The unrestricted validity of AT1, AT2, however, is at odds with other principles which were widely accepted by medieval logicians, namely the law Ex Impossibili Quodlibet, EIQ, and the rules of disjunction introduction. Since, according to EIQ, the impossible proposition (p ∧ ∼p) implies every proposition, it also implies ∼(p∧∼p), in contradiction to AT2. Furthermore, by way of disjunction introduction, the proposition (p∨∼p) is implied both by p and by ∼p, in contradiction to AT1. Kilwardby tried to defend AT1, AT2 against these objections by claiming that EIQ holds only for accidental but not for natural implications. The second argument, however, cannot be refuted in this way because Kilwardby had to admit that every disjunction (p ∨ q) is naturally implied by its disjuncts. He therefore introduced the further requirement that, in order to constitute a genuine counterexample to AT1, (p → q) and (∼p → q) have to hold “by virtue of the same thing”. In a recently published paper, Spencer Johnston accepted this futile defence of AT1 and developed a formal semantics that would fit Kilwardby’s presumably connexive implication. This procedure, however, is misguided because the remaining considerations of Lesson 55  which were entirely ignored by Johnston  show that Kilwardby eventually recognized that AT2 is bound to fail. After all he concluded: “So it should be granted that from the impossible its opposite follows, and that the necessary follows from its opposite”. (shrink)

Leibniz's development of a "calculus universalis" stands and falls with his theory of negation. During the entire period of the elaboration of the algebra of concepts, L1, Leibniz had to struggle hard to grasp the difference between propositional and conceptual negation. Within the framework of syllogistic, this difference seems to disappear because 'Omne A non B' may be taken to be equivalent to ‘Omne A est non-B’. Within the "universal calculus", however, the informal quantifier expression 'omne' is to be dropped. (...) Accordingly, ‘A non est B' expresses only the propositional negation of ‘A est B' and is hence logically weaker than ‘A est non-B'. Besides Leibniz's cardinal error of confusing propositional and conceptual negation the following issues are dealt with in this paper: -"Aristotelian" vs. "Scholastic" Syllogistic; – Metalinguistic theory of the truth-predicate; -Individual-concepts vs. concepts in general.

Freud’s metapsychology has been interpreted in a number of different ways. Some scholars see him committed to classical scientism, others to genuine hermeneutics. Many Freud philologists suggest that he moved from an early scientism to hermeneutic methods in his later writings, and some think he misunderstood his own angle, thinking himself to be a natural scientist, but actually practising hermeneutics. The article first looks at Freud’s model of the soul and his remarks about psychoanalytic explanations and concludes that there is (...) overwhelming evidence for the contention that he conceived of psychoanalytic explanations in terms of causal explanations and that his metapsychology is, all things considered, scientistic. However, it seems that Freud did not clearly distinguish between causal and rational explanations. The article emphasizes that he could have found this distinction in the writings of Max Weber. In the last two sections, the article turns to a meticulous analysis of two vignettes describing Freud’s own treatment of two cases that he takes to be fine examples of the technique used in psychoanalytic treatment. It turns out that Freud himself looks at these cases and their treatment, throughout, in terms of rationality and irrationality. In particular, he seems to distinguish between an “external” irrationality and an “internal” rationality of neurotic diseases. He also seems to point to functions of neuroses representing certain solutions for mental disturbances. Thus, there is much evidence for assuming that in his psychoanalytic technique, Freud relied on genuine hermeneutic and functional methods; and therefore, Freud’s official metapsychology seems to be methodologically inconsistent with his analytic technique.

Verfasser behandelt die Frage, ob die Naturwissenschaften ihre gegenwärtige Hauptfunktion, die Lieferung technikrelevanter Erkenntnisse, wirksamer als bisher erfüllen könnten, wenn sie sich nicht nur während revolutionärer Perioden, sondern ununterbrochen theoretisch pluralistisch entwickeln würden. Zuerst wird gezeigt, warum die Naturwissenschaften unter der Forderung nach maximaler Effektivität stehen, anschließend, daß diese Forderung durch einander abwechselnde pluralistische und nichtpluralistische Entwicklungsphasen in höherem Grade erfüllt wird als durch eine permanent pluralistische Entwicklung. Daraus wird geschlossen, daß eine Ersetzung der bisherigen Entwicklungsdynamik in den Naturwissenschaften durch (...) eine permanent pluralistische wenig Realisierungschancen hat. Mit Hilfe der Effektivitätsforderung wird ferner erklärt, warum auch während evolutionärer Perioden in einem gewissen Ausmaß theoretischer Pluralismus besteht, insbesondere, warum in der Praxis neue Theorien bei Mißerfolgen nicht strikt eliminiert werden, sondern Bewährungsfristen erhalten.

Aristoteles hat seine Lehrschriften sicherlich sowohl als Vorlesungsmanuskripte für seine Schüler als auch für ein abstraktes Publikum und für die Nachwelt geschrieben. Denn wir finden sowohl Bezugnahmen auf seine Hörer als auch Bemerkungen, die einzelne seiner Thesen selbstbewusst im positiven Sinne mit der Leistung der Vorgänger vergleichen und in einen historischen Zusammenhang stellen, was nur sinnvoll ist, wenn der Vergleich von außen nachvollzogen warden konnte. Wieweit einzelne Schriften zu seinen Lebzeiten in Umlauf kamen, ist unbekannt.

The focus of this contribution lies on eighteenth-century chemistry up to Lavoisier’s anti-phlogistic chemical system. Some main features of chemistry in this period will be examined by discussing classificatory practices and the understanding of the substances these practices imply. In particular, the question will be discussed of whether these practices can be regarded as natural historical practices and, hence, whether chemistry itself was a special natural history (part I). Furthermore, discussion of the famous Methode de nomenclature chimique (1787) raises the (...) question of what modes of classification tell us about chemists’ understanding of the substances they deal with (part II). Finally, in investigating what taxonomic orders reveal about deep structures of chemists’ understanding of the world of substances, the contribution will examine the question of whether Lavoisier’s anti-phlogistic chemical system was a revolution on the level of a deep structure or a revision within the untouched frame of such a structure (part III).

The article describes »structures ofresponsible life« in Tödt's theological thinking. (1) As a professor Tödt taught an ethos of matureself responsibility. (2) He was led from exegesis to social ethics by the task of interpreting the gospel in our present time. Tödt explores analogies and differences between options of our present time and the fundamental directions ofChristian faith, especially through such topics as peace and human rights. (3) In a world characterized by modern science and technology, human beings are themselves (...) responsible for the norms of their actions in the sense of a cooperatio hominis cum deo that responds to God. (4) Tödt's ethical heory of moral reasoning tends to an ethic of action. (5) As an historian, the theologian is also accountable for hisfundamental world view. For Tödt, in his research of the Bonhoeffer-Dohnanyi circle's resistance, taking sides with the victims was central. (shrink)

Laws are true lawlike sentences. But what is lawlikeness? Much effort went into investigating the issue, but the richer the concert of opinions became, the more apparent their deficiencies became too, and with it the profound importance of the issue for epistemology and philosophy of science.

Aus epistemisch-logischer Sicht reduziert sich das Fundamentalismusproblem auf die Fragen, ob die Bedingung "a's Glaube, daß p, ist fundiert" notwendig bzw. — im Verband mit "p ist wahr" und "a ist davon überzeugt, daß p " — auch hinreichend dafür ist, daß a weiß, daß p. Drei Explikationsversuche der Fundiertheitsbedingung werden untersucht: während die ersten beiden, mit den üblichen epistemischen Termen 'wissen' und 'überzeugt sein' formulierten Varianten scheitern, erweist sich die dritte Definition mittels des Terms 'evident sein' als erfolgversprechend, sofern (...) "p ist evident für a" seinerseits durch die Bedingungen "a ist davon überzeugt, daß p" und "a kann sich bezüglich p nicht irren" definiert wird. Die genauere Bestimmung des 'kann' als (alethischen) Modaloperator ist ein offenes Problem. (shrink)
