Ordinary language and scientific discourse are filled with linguistic expressions for dispositional properties such as “soluble,” “elastic,” “reliable,” and “humorous.” We characterize objects in all domains – physical objects as well as human persons – with the help of dispositional expressions. Hence, the concept of a disposition has historically and systematically played a central role in different areas of philosophy ranging from metaphysics to ethics. The contributions of this volume analyze the ancient foundations of the discussion about disposition, examine the (...) problem of disposition within the context of the foundation of modern science, and analyze this dispute up to the 20th century. Furthermore, articles explore the contemporary theories of dispositions. (shrink)

Gregor Schiemann verteidigt die Aktualität des aristotelischen und cartesianischen Naturbegriffes, die Natur in Gegensatz zu Nichtnatürlichem definieren. Als gültig könnnen sich diese traditionellen Naturbegriffe jedoch nur noch innerhalb begrenzter Kontexte erweisen. -/- Im ersten Teil seines Buches zeigt der Autor, dass Aristoteles' Bestimmung der Natur als Gegenbegriff zur Technik in der Lebenswelt sowie Descartes' Dualismus von Natur und Geist für das eigene Bewusstseinserleben orientierungsleitend geblieben sind. Dass die Begriffspaare nicht nur in gesonderten Kontexten vorkommen, sondern sich ihre Anwendungen auch (...) wechselseitig durchdringen, führt er im zweiten Teil am Beispiel von Aristoteles' Seelenlehre und Descartes' Mechanismus aus. Die naturphilosophische und erkenntnistheoretische Untersuchung verbindet Elemente der analytischen Philosophie mit Ansätzen der Phänomenologie. Sie will zu einem pluralen Verständnis der Natur beitragen, das universelle Geltungsansprüche verabschiedet. (shrink)

Do the changes that have taken place in the structures and methods of the production of scientific knowledge and in our understanding of science over the past fifty years justify speaking of an epochal break in the development of science? Gregor Schiemann addresses this issues through the notion of a scientific revolution and claims that at present we are not witnessing a new scientific revolution. Instead, Schiemann argues that after the so-called Scientific Revolution in the sixteenth and seventeenth centuries, (...) a caesura occurred in the course of the nineteenth century that constituted a departure from the early modern origins of science. This change was characterized by the loss of certainty on the part of the scientists, by the steadily increasing importance of scientific communities (rather than individuals), and by the systematic intertwinement of scientific and societal development. As to present science, Schiemann admits that important changes have occurred, but he denies the conflation of nature and culture: even the OncoMouse is a natural organism, though a seriously damaged one.

The aim of this paper is to develop and defend an Attentional View of bodily awareness, on which attention is necessary for bodily awareness. The original formulation of the Attentional View is due to Marcel Kinsbourne. First, I will show that the Attentional View of bodily awareness as formulated by Kinsbourne is superior to other accounts in the literature for characterizing the relationship between attention and bodily awareness. Kinsbourne’s account is the only account in the literature so far which can (...) accommodate key neurological diseases such as personal neglect. Second, when I consider Kinsbourne’s view in more detail, I will argue that Kinsbourne’s Attentional View faces problems because it is too reductive. Kinsbourne deviates from the standard taxonomy on which there is a body schema and a body image. Instead he reduces the body image to the neural representation of the body in the somatosensory cortex, the body schema and attentional shifts. I will present two challenges to Kinsbourne’s view which demonstrate that Kinsbourne’s reduction of the body image is unsuccessful. Finally, I will present a revised version of the Attentional View that is both empirically adequate and philosophically satisfactory. (shrink)

Two seemingly contradictory tendencies have accompanied the development of the natural sciences in the past 150 years. On the one hand, the natural sciences have been instrumental in effecting a thoroughgoing transformation of social structures and have made a permanent impact on the conceptual world of human beings. This historical period has, on the other hand, also brought to light the merely hypothetical validity of scientific knowledge. As late as the middle of the 19th century the truth-pathos in the natural (...) sciences was still unbroken. Yet in the succeeding years these claims to certain knowledge underwent a fundamental crisis. For scientists today, of course, the fact that their knowledge can possess only relative validity is a matter of self-evidence. The present analysis investigates the early phase of this fundamental change in the concept of science through an examination of Hermann von Helmholtz's conception of science and his mechanistic interpretation of nature. Helmholtz (1821-1894) was one of the most important natural scientists in Germany. The development of this thoughts offers an impressive but, until now, relatively little considered report from the field of the experimental sciences chronicling the erosion of certainty. (shrink)

The so-called ”argument from religious experience’ plays a prominent role in today’s analytical philosophy of religion. It is also of considerable importance to richard Swinburne’s apologetic project. However, rather than joining the polyphonic debate around this argument, the present paper examines the fundamental concept of religious experience. The upshot is that Swinburne neither develops a convincing concept of experience nor explains what makes a religious experience religious. The first section examines some problems resulting mainly from terminology, specifically Swinburne’s use of (...) appear-words as success-verbs. While these problems might be resolved by a recurrence to the observer, the second and third part of our paper present problems not so easily resolved: namely, that Swinburne’s concept of experience as conscious mental events is too broad and inaccurate for its role in the argument given ; and that Swinburne does not even attempt to figure out which features of an experience, when present, turn an experience simpliciter into a distinctly religious experience. Section 4, in conclusion, outlines possible reasons for this unusual and remarkable inaccuracy in conceptualisation. (shrink)

The paper deals with the question of the structure of knowledge and the precise relationship between propositional "knowledge that" and dispositional "knowledge how." In the first part of my essay, I provide an analysis of the term 'knowing how' and argue that the usual alternatives in the recent epistemological debate – knowing how is either a form of propositional or dispositional knowledge – are misleading. In fact it depends on the semantic and pragmatic context of the usage of this term (...) whether 'knowing how' refers to a type of dispositional knowledge, to propositional knowledge, or to a hybrid form of both. Only in the first case, can one say that dispositional know how cannot be reduced to any form of propositional knowledge. Yet, this case is the most interesting one to consider in the investigation of the nature of knowledge, if one assumes that knowing that p presupposes "having found out that p." Having found something out, however, presupposes certain acts of epistemic inquiry and corresponding epistemic abilities. Examined more carefully, it is shown that the dispositional knowledge-how is a necessary condition for propositional knowledge-that, hence propositional knowledge-that is a species of the dispositional knowledge-how. Accordingly, dispositional knowledge has to be understood as being at the very core of our notion of knowledge, including propositional knowledge. (shrink)

Limits of the Conversation about Forms. Types of Knowledge and Necessity of Forms in Plato's "Parmenides". - Forms (ideas) are among the things that Plato is serious about. But about these things he says in his "Seventh Letter": "There neither is nor ever will be a treatise of mine on the subject." (341c, transl. J. Harward). Plato's statement suggests the question, why one does not and never can do justice to the Platonic forms by means of a written text about (...) the forms. Another big question of Plato research is whether the conversations documented in the Platonic dialogues are also affected by this verdict. This paper aims to provide, as far as possible, newly substantiated answers to these two questions. To this end, the systematic limits of the discussion about forms, which are particularly evident in Plato's dialogue "Parmenides", are examined in eight steps: First, two types of knowledge are presented that play an important systematic role in Plato's philosophy with regard to the limits of conversation: knowledge-how (practical knowledge) and knowledge-that (propositional knowledge) (I). Then the Socratic model of these two types of knowledge is interpreted, which is drafted in the tenth book of the "Republic". This model uses the example of bridle, bridlemaker and rider to explain the primacy of practical knowledge and the limits of propositional knowledge (II). Subsequently, it will be shown how the dialogues "Republic" and "Parmenides" are connected with each other in content and form (III). The gradation of the two types of knowledge, which is indicated by the motifs of the bridle and the horse on the image level of the "Parmenides", proves to be the structure that systematically underlies the structure of the entire dialogue (IV). It also makes clear why the conversation about the forms in the first part of the "Parmenides" has to fail (V). The assumption that the two parts of the "Parmenides" express two different types of knowledge in dealing with forms is supported by the results of a logical analysis of the last defence of the acceptance of forms (135b-c). This analysis shows why, for reasons of principle, it is impossible to speak adequately about forms (VI). Forms have the function of being presuppositions of 'talking about something'. Thus forms are always presupposed in conversation when one talks about them, and thus elude appropriate discussion in conversation (VII). That this is not only a methodical insight of the Platonic Parmenides, but can also be attributed to Plato himself, is demonstrated by the concluding reinterpretation of the central sentence of the critique of writing in Plato's "Seventh Letter". It will become apparent that, contrary to the now widespread view of the representatives of the Tübingen school, philosophical and also good philological reasons speak for the fact that Plato related his criticism only to the communicability of forms through treatises, i.e. tract-like writings (VIII).

Der Verzicht auf absolut gültige Erkenntnis, heute in den Naturwissenschaften beinahe schon selbstverständlich, ist erst jüngeren Datums. Noch im vergangenen Jahrhundert zweifelte die experimentelle Forschung kaum an der vollkommenen Begreifbarkeit der Welt. Diesen Wandel zu erkunden und aufzuzeigen ist Thema der vorliegenden Studie. Der erste Teil präsentiert verschiedene Typen neuzeitlicher und moderner Wissenschaftsauffassungen von Galilei über Newton bis hin zu Kant. Im zweiten Teil werden Entwicklung und Wandel der Wissenschafts- und Naturauffassung bei Helmholtz (1821-1895) erstmals mittels detaillierter Textanalysen einer umfassenden (...) Rekonstruktion unterzogen. Die Relativierung des Wahrheitsanspruchs erlaubt es Helmholtz, seine Naturauffassung trotz der antimechanistischen Kritik innerhalb der Physik, die im letzten Viertel des vergangenen Jahrhunderts laut wurde, als Hypothese aufrechtzuerhalten. Auch gewährt die Studie eine neue Sichtweise des Verhältnisses zwischen Helmholtz und Kant, das in der Vergangenheit kontroverse Beurteilungen erfuhr. (shrink)

This commentary challenges Railton’s claim that the affective system is the key source of control of action. Whilst the affective system is important for understanding how acting for a reason is possible, we argue that there are many levels of control of action and adaptive behaviour and that the affective system is only one source of control. Such a model seems to be more in line with the emerging picture from affective and movement neuroscience.

I would like to assume that Reichenbach's distinction of Justification and Discovery lives on, and to seek arguments in his texts that would justify their relevance in this field. The persuasive force of these arguments transcends the contingent circumstances apart from which their genesis and local transmission cannot be made understandable. I shall begin by characterizing the context distinction as employed by Reichenbach in "Experience and Prediction" to differentiate between epistemology and science (1). Following Thomas Nickles and Kevin T. Kelly, (...) one can distinguish two meanings of the context distinction in Reichenbach's work. One meaning, which is primarily to be found in the earlier writings, conceives of scientific discoveries as potential objects of epistemological justification. The other meaning, typical for the later writings, removes scientific discoveries from the possible domain of epistemology. The genesis of both meanings, which demonstrates the complexity of the relationships obtaining between epistemology and science, can be made understandable by appealing to the historical context (2). Both meanings present Reichenbach with the task of establishing the autonomy of epistemology through the justification of induction. Finally, I shall expound this justification and address some of its elements of rationality characterizing philosophy of science(3). (shrink)

Suppose a fire broke out in a fertility clinic. One had time to save either a young girl, or a tray of ten human embryos. Would it be wrong to save the girl? According to Michael Sandel, the moral intuition is to save the girl; what is more, one ought to do so, and this demonstrates that human embryos do not possess full personhood, and hence deserve only limited respect and may be killed for medical research. We will argue, however, (...) that no relevant ethical implications can be drawn from the thought experiment. It demonstrates neither that one always ought to let the embryos die, nor does it allow for any general conclusion concerning the moral status of human embryos. (shrink)

Die Darstellung konzentriert sich auf den Naturbegriff in seinem Verhältnis zu Kultur, die folglich nur reduzierte Charakterisierung erfährt. Herausgearbeitet werden vor allem die Umfänge, Eigenschaften und Grenzen der auf Kultur bezogenen Naturbegriffe. Das Feld dieser Bedeutungen ist in einer Pluralität von sich teils überschneidenden, teils wechselseitig ergänzenden Naturbegriffen eingebettet. Weil erst vor diesem Hintergrund die Spezifität der Beziehung von Natur und Kultur sowie ihrer Natur - Kultur und ihr Anderes Bestimmungselemente deutlich wird, beginne ich mit einer Vorbemerkung zum Naturdiskurs (1). (...) Im Anschluss daran stelle ich fünf Varianten der Verhältnisbestimmung von Natur und Kultur vor. Bei den ersten beiden handelt es sich um die klassischen Entgegensetzungen von Natur zu Technik einerseits und zu Geschichte andererseits. Die Differenz von Natur und Technik geht auf Aristoteles zurück und hat sich bis heute vor allem Aktualität im lebensweltlichen Erfahrungsbereich bewahrt. (2). Den lebensweltlichen Nahbereich des direkt Wahrnehm- und Veränderbaren transzendiert die exemplarisch von Jean-Jacques Rousseau formulierte Gegenüberstellung von Natur und Geschichte. (3). Übergangsbereiche von Natur und Kultur sowie Bereiche, in denen sich zwischen beiden nicht mehr sinnvoll unterscheiden lässt, sind in den vergangenen zwei Jahrhunderten zunehmend zum Gegenstand wissenschaftlicher Arbeit geworden. Die Vielfalt der gegenwärtigen Forschungen in diesem Zusammenhang gestattet keine einheitliche Bestimmung des Natur-Kultur-Verhältnisses. Es lassen sich jedoch gemeinsame Strukturen bevorzugter Thematisierungsrichtungen ausmachen. Dazu gehört das Festhalten an den beiden, nicht dualistisch aufgefassten Begriffen als Bezeichnung von Gegenstandskomponenten. Hieran anknüpfend schlage ich vor, die Begriffe als polare Extreme eines Feldes von Mischungszuständen zu verstehen (4). Abschließend folgen die zwei Varianten, in deren Konsequenz es liegt, die Legitimität jeweils eines der beiden Begriffe zu bestreiten: Die naturalistische und die kulturalistische Variante. Sie rekurrieren jeweils beide auf einen historischen Prozess und sind als theoretisches Programm formuliert (5 und 6). (shrink)

Gregor Schiemann führt allgemeinverständlich in das Denken dieses Physikers ein. Thema sind die Erfahrungen und Überlegungen, die Heisenberg zu seinen theoretischen Erkenntnissen geführt haben, die wesentlichen Inhalte dieser Erkenntnisse sowie die Konsequenzen, die er daraus für die Geschichte der Physik und das wissenschaftliche Weltbild gezogen hat. Heisenbergs Vorstellungswelt durchzieht durch ein Spannungsverhältnis, das heute noch das Denken vieler Wissenschaftlerinnen und Wissenschaftler bewegt. Er ist um ein umfassendes Verständnis der Naturprozesse bemüht, zugleich aber von der Berechenbarkeit und Beherrschbarkeit von Phänomenen (...) auch dann schon fasziniert, wenn die zugrunde liegenden Prozesse erst teilweise verstanden sind. Aus der Geschichte der Physik zieht er die wirkungsreiche Lehre, daß sich die naturwissenschaftliche Erkenntnis nicht kontinuierlich, sondern sprunghaft in Form von Revolutionen entwickelt. Die Reichweite des physikalischen Wissens begrenzt er in einer Schichtentheorie der Welt, nach der die komplexen Phänomene des Lebens nicht allein durch die Wechselwirkungen zwischen ihren Bestandteilen erklärt werden können. Der zunehmenden Technisierung der Welt steht Heisenberg kritisch gegenüber. Seiner Zeit weit voraus, glaubt er, daß die Technisierung der Welt eine epochal neue Stufe erreicht habe, in der der Mensch „nur noch sich selbst“ gegenüberstehe. (shrink)

From the point of view of the history and philosophy of science, the relationship of Descartes' to Aristotle's concept of nature has not been grasped in an entirely satisfactory way. In this article, the two concepts will be subjected to a comparative analysis, beginning with the outstanding feature that both concepts of nature are characterized by a contradistinction to the non-natural: Aristotle separates nature and technology; Descartes opposes nature to thinking. My thesis is that these meanings have found privileged application (...) in specific contexts of experience: the field of application especially suitable for the Aristotelian concept is the experience of everyday life, while for the Cartesian concept it is subjective experience. Historically, the relationship between meaning and experience is of help in understanding the conditions in which the two concepts arose. The topical relevance of the concepts to modern society is a consequence of the continued existence of the favored contexts of experience. Roughly stated, we sometimes still perceive in an Aristotelian way and at other times think in a Cartesian way. (shrink)

Das Verhältnis von Geschichts- und Naturwissenschaft ist zwischen 1880 und 1945 - dem hier zu betrachtenden Zeitraum - durch einen Differenzierungsprozeß bestimmt, in dem sich die Geschichtswissenschaft gegenüber dem verstärkten Einfuß der naturwissenschaflichen Methode auf die Erfahrungswissenschaften abzugrenzen versucht und die Naturwissenschaft von der Historizität ihrer eigenen Erkennmisse zunehmend absieht. Diese allgemeine Tendenz setzt sich jedoch bei weitem nicht ungebrochen durch. Sie ist in eine komplexe Struktur von thematischen und interdisziplinären Beziehungen eingelassen, in der zahlreiche gegenläufige, kaum einheitlich zu charakterisierende (...) Bewegungen wirksam sind. Will man sich einen Überblick über diese verwickelten Verhältnisse verschaffen, empfiehlt es sich, von einem vereinfachenden Schema auszugehen und zwischen vier disziplinären Kontexten zu unterscheiden:der Geschichtswissenschaft, dem naturalistischen Geschichtsdenken, der Naturwissenschaft und der Wissenschaftsgeschichtsschreibung der Naturwissenschaft. Entlang dieser Einteilung möchte ich thesenartig auf Aspekte der wissenschaftlichen Thematislerung von Natur und Geschichte eingehen, die mir für die geschichtstheoretischen Diskurse besonders relevant zu sein scheinen.

Zuerst werden die Argumente rekonstruiert, die dafür sprechen, Einsteins Wort, dass Gott nicht würfelt, als Ausdruck eines überholten deterministischen Weltbildes anzusehen. Anschließend werden Forschungsergebnisse der letzten Jahrzehnte benannt, die für eine Neubewertung seiner Position zur dominanten Interpretation der Quantenmechanik sprechen. Den Abschluß bildet die Diskussion der Möglichkeiten einer Reinterpretation seines Satzes vom nicht würfelnden Gott.

Nach einer kurzen Erinnerung an einige von Keplers Hauptwerken, in denen traditionelle und moderne Elemente eingehen (Abschnitt 1), wird zwei Beispielen die Differenz zwischen diesen beiden Elementen näher untersucht. Das erste Beispiel, Keplers Naturbegriff, dient zur Diskussion der Kritik qualitativer Unterscheidungen. Hierbei stehen Keplers Verhältnis zur aristotelischen Naturauffassung und die Relevanz dieser Relation für die moderne Wissenschaftsauffassung im Mittelpunkt (Abschnitt 2). Das andere Beispiel befasst sich mit dem absoluten Wahrheitsanspruch von Keplers Wissenschaft und rückt damit exemplarisch eine Differenz zur modernen (...) Wissenschaftsauffassung in den Vordergrund (Abschnitt 3). Anschließend werden umfassender traditionelle Elemente der frühneuzeitlichen Wissenschaft, wie sie Kepler vertrat, dem modernen Wissenschaftsverständnis gegenübergestellt. Nachdem damit die Entfernung Keplers zur Gegenwart gleichsam maximiert ist, wende ich mich den Wissenschaftsauffassungen von Wolfgang Pauli und Werner Heisenberg zu, die in bemerkenswerter Nähe zu Keplers vormodernen Ansichten stehen und doch ganz im Kontext der Moderne entwickelt wurden (Abschnitt 4). Obwohl also in jüngster Zeit ganz differente Einstellungen zu Keplers Verhältnis zur modernen Wissenschaft vertreten wurden, lässt sich doch eine Tendenz zur Abstandsvergrößerung in dieser Relation ausmachen (Abschnitt 5).

In his "Ontological proof", Kurt Gödel introduces the notion of a second-order value property, the positive property P. The second axiom of the proof states that for any property φ: If φ is positive, its negation is not positive, and vice versa. I put forward that this concept of positiveness leads into a paradox when we apply it to the following self-reflexive sentences: (A) The truth value of A is not positive; (B) The truth value of B is positive. Given (...) axiom 2, sentences A and B paradoxically cannot be both true or both false, and it is also impossible that one of the sentences is true whereas the other is false. (shrink)

Als Vertreter der historischen Anthropologie hat Christoph Wulf die philosophische Anthropologie von Max Scheler, Helmuth Plessner und Arnold Gehlen kritisiert: Mit ihrem Interesse an einer einheitlichen Bestimmung des Menschen entgehe ihr die Pluralität von menschlichen Kulturen. Meiner Auffassung nach stellt diese Kritik für die philosophische Lehre vom Menschen eine Herausforderung dar (1.). Um ihr zu begegnen, möchte ich prüfen, ob Ernst Cassirers Kulturphilosophie die Vielfalt menschlicher Erfahrungsweisen angemessener berücksichtigt. Dass dies nicht in hinreichendem Umfang der Fall ist, lässt sich auf (...) eine bei Cassirer vorherrschende Einheitsorientierung zurückführen, die bezeichnende Berührungspunkte zu Hegels Idealismus aufweist. Der von Kant über Hegel zu Cassirer führende philosophische Diskurs über den Menschen hat zwar der Thematisierung einer irreduziblen Erfahrungspluralität zunehmend Raum verschafft, ist aber zugleich auf eine einheitliche Verfassung des Geistes bezogen geblieben (2.). Will die philosophische Anthropologie der kulturellen Vielfalt gerechter werden, muss sie über Cassirers Ansatz hinausgehen und ihre Fokussierung auf eine die menschliche Welt durchdringende Bestimmung des Geistes weiter abschwächen, wenn nicht sogar aufgeben. Als einen hierfür förderlichen Ausgangspunkt, betrachte ich die Sozialphänomenologie von Alfred Schütz. Sie erlaubt die Begründung einer nicht hierarchisch strukturierten Pluralität der Erfahrung. Im Anschluss an Schütz' Konzeption muss der Philosophie mit ihrem legitimen Interesse an dem Menschen nicht die Vielfalt der Menschen abhanden kommen. Pluralität ist dem Menschen vielmehr als Bestimmung eingeschrieben (3.). (shrink)

Die Deutsche Forschungsgemeinschaft (DFG) hat ab 2016 eine neue Forschergruppe unter Leitung der Bergischen Universität Wuppertal eingerichtet. Sie untersucht die Forschungen an der „größten Forschungsmaschine der Welt“, dem Large Hadron Collider (LHC) am Europäischen Zentrum für Teilchenphysik CERN in Genf, aus philosophischer, historischer und soziologischer Sicht. Wissenschaftsphilosophisch sind diese Forschungen vor allem aus drei Gründen relevant: Die Philosophie interessiert sich für den Ursprung und die grundlegenden Strukturen der Welt, für die Bedingungen des Erkenntniserfolges der Elementarteilchenphysik und nicht zuletzt für die (...) mit den Erfolgen mitunter eng verbundenen theoretischen und praktischen Probleme. Die Diskussion dieser Gründe zeigt die Elementarteilchenphysik als eine lebensweltferne, zugleich aber weltbildrelevante, theoretisch wie praktisch äußerst erfolgreiche Disziplin, die dennoch nicht frei von gewichtigen offenen Fragen ist. Sie könnte ein Typus für die Gewinnung von Wissen an den Grenzen unserer Erkenntnis sein. (shrink)

When in doubt, for the embryo. New arguments on the moral status of human embryos. - In the first part of our essay we distinguish the philosophical from the legal and political level of the embryo debate and describe our indirect justification strategy. It consists in renouncing a determination of the dignity-giving φ-properties and instead starting from premises that are undoubted by all discussion partners. In the second part we reconstruct and criticize the species, continuum, identity and potentiality arguments. The (...) species argument only has a certain plausibility, if at all, as a critical argument. From the continuum argument and identity argument we take over the idea of numerical identity (NI) and link it with the core idea of the potentiality argument (P). So we come to the NIP argument: -/- (NIP) -/- (1) Every living human body that is the bearer of (or has) potential φ-properties has dignity. (2) Every viable human embryo is a living human body that is the bearer of (or has) potential φ properties. Therefore, (3) Every viable human embryo has dignity. -/- Reversibly comatose people and newborns are protected because they have the potential to have actual personal characteristics in the future; our thesis is that embryos that are capable of development also have the same potential in moral terms. The basic idea of numerical identity, with which we support the second premise, is that every human being, from embryonic existence to adulthood, forms a physical unity. In a detailed part, we deal with the crown princess, gametes, parthenogenesis, somatic cell, pronuclear stage, biological heteronome early embryo, multiple, fusion, Siamese twin, hydatidiform mole and finally trophoblast problems. In a third part, the indirect argument is supplemented by a metatheoretical cautionary argument. It states that in situations where there is doubt as to whether a being falls within the scope of a moral norm, but there are sufficiently strong reasons for this subsumption, it must be assumed that this is the case if the contrary assumption and the positive effects it may have are in no acceptable proportion to the moral harm that would result if that subsumption were not made. The main result of our considerations is therefore: When in doubt, for the embryo. (shrink)

In his Paradoxes (1995: Cambridge University Press: 149) Mark Sainsbury presents the following pair of sentences: Line 1: The sentence written on Line 1 is nonsense. Line 2: The sentence written on Line 1 is nonsense. Sainsbury (1995: 149, 154) here makes three assertions: (1) The sentence in Line 1 is so viciously self-referential that it falls into the truth-value gap. The sentence is really nonsense. (2) The sentence in Line 2 is by contrast true. For it states precisely that (...) the sentence in Line 1 is nonsense. (3) The two sentences in Lines 1 and 2 are an example of the principle that two sentence tokens of the same sentence-type can have different truth-values, although they have the same reference and state the same property of the object of reference. In this paper, I argue that Sainsbury’s assumptions are false in all three cases. (shrink)

Obwohl Rousseaus Mitleidsbegriff in heutige Verständnis weisen des Mitleids eingegangen ist spielt er in ihren Thematisierungen nur eine eher untergeordnete Rolle. Rousseaus Beitrag zum modernen Begriffsverständnis steht einerseits im Schatten des Einflusses anderer ethischer Gefühlsauffassungen. Andererseits liegen Ursachen für die periphere Stellung des Begriffes darin, dass er in Rousseaus Werk selbst nur an wenigen Stellen erörtert wird. Meine These ist, dass Rousseaus Begriff eine für die Moderne kennzeichnende ambivalente Struktur aufweist, die aus der Dominanz des Selbstbezuges resultiert. Die Rekonstruktion des (...) Begriffes gliedert sich in drei Teile: Zuerst verorte ich seine Position in Rousseaus Werk und fasse seine Bestimmungen zusammen; dann diskutiere ich seine Ambivalenzen auf der Ebene des individuellen Mitleidserlebens; abschließend nehme ich eine Revision und eine Bewertung des Begriffes vor.

Plato’s Timaeus gives an account of the creation of the world and of human race. The text suggests that there was a first generation of human beings, and that they were all men. The paper raises difficulties for this traditional view, and considers an alternative, suggested in more recent literature, according to which humans of the first generation were sexually undifferentiated. The paper raises difficulties for the alternative view as well, and examines the third possibility, advocated by some ancient as (...) well as modern interpreters, according to which there were no first humans, strictly speaking. Although the latter view avoids the pitfalls of the former two views, it crucially rests on a metaphorical reading of the creation story in the Timaeus. (shrink)

Reflective equilibrium (RE) is often regarded as a powerful method in ethics, logic, and even philosophy in general. Despite this popularity, characterizations of the method have been fairly vague and unspecific so far. It thus may be doubted whether RE is more than a jumble of appealing but ultimately sketchy ideas that cannot be spelled out consistently. In this paper, we dispel such doubts by devising a formal model of RE. The model contains as components the agent’s commitments and a (...) theory that tries to systematize the commitments. It yields a precise picture of how the commitments and the theory are adjusted to each other. The model differentiates between equilibrium as a target state and the dynamic equilibration process. First solutions to the model, obtained by computer simulation, show that the method allows for consistent specification and that the model’s implications are plausible in view of expectations on RE. In particular, the mutual adjustment of commitments and theory can improve one’s commitments, as proponents of RE have suggested. We argue that our model is fruitful not only because it points to issues that need to be dealt with for a better understanding of RE, but also because it provides the means to address these issues.

The topic of this contribution is the tension between the everyday dichotomy of nature and technology and the nanotechnological understanding of the world. It is essential to nanotechnology that nature and technology not be categorically opposed as the manmade and the non-manmade, but rather regarded as parts of a structurally identical whole. After the introduction, I will address three points: In a brief first section I will formulate a few questions and a thesis about the nanotechnological developments that can be (...) expected to come. In the main section I will assess four aspects of everyday understanding of nature and technology that are used to legitimate nanotechnology. Finally I will discuss whether an everyday understanding of nature can be conceived as a critical authority with respect to the nanotechnology program. (shrink)

Inwieweit vermag sich der ehemalige explanative Erfolg nicht mehr anerkannter Theorien auf die Geltung derjenigen Teilaussagen, die Nachfolgetheorien übernommen haben, zu stützen? Zur Klärung dieser Fragestellung können die Ergebnisse von Machs Untersuchung zur mechanistischen Auffassung des Energieerhaltungssatzes herangezogen werden. Indem er sich in seiner Kritik an den ontologischen Annahmen des Mechanismus auf die Wissenschaftsgeschichte beruft, steht er einer heutigen realismuskritischen Argumentation nahe. Andererseits mißt er den hypothesenfreien Theoriebestandteilen einen Geltungscharakter zu, der in seinem Wahrheitsanspruch durchaus mit einer heutigen realistischen Behauptung (...) theorieübergreifender Bestände der wissenschaftlichen Erkenntnis vergleichbar ist. Daß Mach mit einer quer zur gegenwärtigen Terminologie liegenden Analyse einen Beitrag zur Entschärfung gegenwärtiger Kontroversen leistet, läßt eine erneute Vergegenwärtigung der Schrift von 1872 und den sich daran anschließenden Überlegungen Machs lohnenswert erscheinen.

Hermann von Helmholtz hat als Naturforscher sowohl die Physik als auch die Physiologie um eine beeindruckende Anzahl grundlegender Erkenntnisse bereichert, ihr heutiges Selbstverständnis entscheidend mitgeprägt, ihre Verfahren auf neue Gegenstandsbereiche angewendet und war führend an ihrem institutionellen Ausbau zu Laborwissenschaften beteiligt.

Helmholtz initially ascribes more to theoretical knowledge than merely that it is a picture of the world: it penetrates even to the unobservable causes of the phenomena which he conceived throughout his career as matter set mechanically in motion. The introduction of the picture-concept in the 1860s to characterize scientific theories marks the beginning of the loss of a direct connection with the world. Theories now constitute only a representation of a law-like structure of the world but no longer shed (...) light on the objects themselves. Beginning in the late 1870s, this knowledge of laws takes on an increasingly hypothetical character. (shrink)

It can be said that Rousseau is one of the most acute thinkers of the corruption of civilisation. In fact, the Second Discourse and the Essay on the Origins of Languages could be read as elaborate analyses of advancing social and cultural decline inasmuch as mankind is continually moving away from the original state of natural innocence. But Rousseau’s idea of corruption is not straightforward. I try to show that in the Essay, Rousseau emphasizes the natural causes for corruption. I (...) argue that an opposition between necessity and contingency, which more accurately represents the two modes operating in Rousseau’s doctrine, should replace the standard nature/culture divide. The contingency of natural catastrophes is found to be ultimately responsible for the corruption in the social realm, which is therefore largely driven by natural causes. (shrink)

The principle of performative contradiction. On the epistemological significance of the dialogue form in Plato's "Euthydemus". - In this study, an analysis of the section 285d-288a of Plato's "Euthydemus" shall show two things: (1) The sophistic model of a world in which there is no contradiction, in which every linguistic utterance is true and every action correct, has no semantic inconsistencies, but can only be rejected with the help of the principle of performative contradictions. (2) It is precisely these performative (...) contradictions that make it necessary for Plato to philosophize not in treatises but in dialogues; in other words, that the philosophical relevance of the Platonic form of dialogue can be seen, among other things, in the fact that - in contrast to philosophical forms of representation such as the treatise, the essay, and a henology as reconstructed and represented by the Tübingen School - it permits the representation of performative reflections and performative contradictions.

Helmholtz's public reflection about the nature of the experiment and its role in the sciences is a historically important description, which also helps to analyze his own works. It is a part of his conception of science and nature, which can be seen as an ideal type of science and its goals. But its historical reach seems to be limited in an important respect. Helmholtz's understanding of experiments is based on the idea that their planning, realization and evaluation lies in (...) the hands of a person or group acting according to decisions of free will. In my opinion this idea is characteristic for the foundation of the experimental method in early modern times, not however for several forms of its present structures. Above all, the increasing technization of producing knowledge reduces the roIe of the subject in conducting experiments. My lecture consists of three parts. In its first part I would like to present a summary of Helmholtz's own theory of experiment and the change of his conception of science and nature. In the second part I would like to discuss three examples of his experimental practice, which were taken in chronological order from three different periods of his work; in the third part I would like to compare the examples with the change of his conception of science and nature.

The Contingency Postulate of Truth. - Is there a statement that cannot be false under any contingent conditions? Two well-known philosophical schools have given contradictory answers to this question about the existence of a necessarily true statement: Fallibilists (Albert, Keuth) have denied its existence, transcendental pragmatists (Apel, Kuhlmann) and objective idealists (Wandschneider, Hösle) have affirmed it. Dieter Wandschneider has (following Vittorio Hösle) translated the principle of fallibilism, according to which every statement is fallible, into a thesis which he calls the (...) contingency postulate of truth (CPT). It says: <For every true statement there are contingent conditions.> If this postulate were true, it would mark an insurmountable boundary of knowledge: a final epistemic justification would then not be possible. Wandschneider has therefore developed a counterargument to show that the contingency postulate of truth cannot be formulated without contradiction and implies the thesis that there is at least one necessarily true statement. This essay deals with the systematic question whether the contingency postulate of truth really cannot be presented without contradiction. To this end I will first present the contingency postulate and the associated problems (I.). Then I will analyze Wandschneider's argument against the consistency of the contingency postulate (II.) and finally reject it with the help of some considerations from the field of epistemic logic (III.).

Descartes and Architecture -/- The article analyses the architectural metaphor in Descartes' Discourse on Method and The Seventh replies. The idea of Descartes' project, introduced to the reader as a construction of a building and planning of a city, is much more indebted to its architectural imagery than, or so its critics say, is "sound" for a philosophical theory. Architecture is an analogon of philosophy in Descartes' texts. By producing a figure of philosopher-architect, Descartes tries to legitimate his philosophical theory (...) using architectural discourse. Descartes always uses the examples of architecture and urban planning when he intends to introduce his great project of a new beginning in philosophy. This new beginning is manifest in two levels: first, as a denial of traditional metaphysics of the Schools in the Discourse, and second, as a denial of one’s own beliefs in the Meditations using methodical doubt. In the conclusion, the article emphasises through Derrida's analysis of metaphor that, given the metaphysical nature of any metaphor, Descartes’ metaphor also cannot appear as a mere rhetorical figure.

Theophrastus' treatise "Metaphysics" contains a compact and critical reconstruction of unsolved systematic problems of classical Greek philosophy. It is primarily about fundamental problems of ontology and natural philosophy, such as the question of the interdependence of principles and perceptible phenomena or the plausibility of teleology as a methodical principle of the explanation of nature. The aim of the critical Greek-German edition (with introduction and commentary) is to make visible the systematic significance of Theophrastus' critique of metaphysics.

"Language and its Public Features: Reorganizing the Trivium in Locke's Essay and Port-Royal Logic" The new theory of language in the 17th century coincides with the end the traditional order of disciplines in the trivium (grammar, logic and rhetoric), which in the mediaeval times provided a comprehensive view of the problems of discourse. The article focuses on some key passages in Port-Royal Logic and Locke's Essay that provide us with a typical early modern scheme of linguistic representation, characterised by heavily (...) emphasized dualism of ideas and words. Since ideas are also the meanings of words and are ontologically essentially private, one can raise the question, where in this analysis of language is it even possible to locate its public features. The article tries to show that private language is not only possible for Locke and the Port-Royalists, but that it is even a necessary and primary character of language. Language becomes a public medium of communication only on the junctures of private meanings constituted by the “common use” of words. The article then focuses on almost complete marginalisation in the two works of the theory of public speech. Rhetoric, in the 17th century often reduced to mere eloquence, has no place in philosophy, and the duties of making speeches persuasive are taken over by reason alone. To show how the domains of jurisdiction of the trivial disciplines had been transformed in the linguistic theories proposed by the Port-Royal Logic and Locke, one can construct a hypothetical early modern trivium in the light of the following order: idea – word – figure, or, logic – grammar – rhetoric. Rhetoric is found to have kept its structural place only to be singled out as dangerous. (shrink)

"Dieu fainéant? God and Bodies in Descartes, Malebranche, and Leibniz" Conservation, concurrence with secondary causes, and occasionalism are the three attitudes that God can have towards the created universe in early modern philosophy. The aim of this article is to show how and in what forms these three originally mediaeval theories had survived the seventeenth century in Descartes, Malebranche, and Leibniz. I argue that although it cannot always be unequivocally determined which of the three doctrines each of the thinkers is (...) indebted to, Descartes should nevertheless be interpreted as a concurrentist, Malebranche as an occasionalist, and Leibniz can be read as a mere conservationist. The conservation of substances in existence being nothing but a continual creation, we claim (against the famous thesis of Alexandre Koyré) that Leibniz’s God can be called neither Dieu fainéant nor God of the Sabbath day.

In the academic literature and elsewhere, specific relativisms are often a hotly debated topic. In this paper, I considerably up the ante by proposing an across the board universal relativism that is supported by four arguments: an inductive argument, an argument from causality, an argument from elimination, and an argument against self-refutation.
