Husserl’s theory of fulfilment conceives of empty acts, such as symbolic thought, and fulfilling acts, such as sensory perceptions, in a strict parallel. This parallelism is the basis for Husserl’s semantics, epistemology, and conception of truth. It also entails that any true proposition can be known in principle, which Church and Fitch have shown to explode into the claim that every proposition is _actually_ known. I assess this logical challenge and discuss a recent response by James Kinkaid. While Kinkaid’s proposal (...) saves one direction of the parallel for semantics, it gives up the parallelism for truth. I spell out a different response which meshes naturally with Husserl’s account of meaning. If the parallelism is restricted to a class of basic propositions, the truth of non-basic propositions can be defined inductively, without leading to the paradox. I then discuss objections that have been raised against a similar proposal by Dummett. The result is that exegetically plausible and popular interpretations of Husserl’s correlationism are indeed challenged by Church and Fitch. But when taking into account the ‘logical adumbration’ of propositional blindspots, truth and possible fulfilment can be connected without paradox. (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)

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)

The conception that the world can be represented as a system of levels of being can be traced back to the beginnings of European philosophy and has lost little of its plausibility in the meantime. One of the important modern conceptions of levels was developed by Nicolai Hartmann. It exhibits remarkable similarities and contrasts with the classification of the real developed by Werner Heisenberg in his paper Ordnung der Wirklichkeit (Order of Reality). In my contribution I will introduce these two (...) conceptions of levels and compare their salient features. I will discuss them as variants of a scientific worldview that attempts to forge a link to the perspective of the lifeworld. Then I will go on to argue that the shortcomings of these conceptions can be remedied by extending them with the level of the very small and that of the very large. The introduction of these ontologically fundamental levels is based on scientific knowledge that for the most part eludes he intuitively representable character of lifeworld experience. Historical changes in science and the lifeworld could lead to the notion that reality can be represented as a system of levels being challenged in future. (shrink)

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)

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

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)

In future φ. On a subjectivist thought experiment in the embryo debate. -.

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)

Werner Heisenberg made an important – and as yet insufficiently researched – contribution to the transformation of the modern conception of science. This transformation involved a reassessment of the status of scientific knowledge from certain to merely hypothetical – an assessment that is widely recognized today. I examine Heisenberg’s contribution in particular by taking his conception of “closed theories” as an example according to which the established physical theories have no universal and exclusive, but only a restricted validity. Firstly, I (...) characterize the historical process of hypothetization of claims to validity. Then, secondly, I reconstruct Heisenberg’s conception, as far as it can be derived from his popular writings, relating it to the process of hypothetization. Finally, I touch on the history of its reception and compare it with conceptions of science that emphasize the significance of the hypothetical for the modern theories of natural sciences. Compared to these conceptions, Heisenberg’s contribution turns out to be rather independent. (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.

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)

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)

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).

Introduction to Debating Dispositions. Issues in Metaphysics, Epistemology, and Philosophy of Mind, ed. by Gregor Damschen, Robert Schnepf, and Karsten R. Stueber, Berlin/New York: de Gruyter 2009.

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.

In searching for the origins of current conceptions of science in the history of physics, one encounters a remarkable phenomenon. A typical view today is that theoretical knowledge-claims have only relativized validity. Historically, however, this thesis was supported by proponents of a conception of nature that today is far from typical, a mechanistic conception within which natural phenomena were to be explained by the action of mechanically moved matter. Two of these proponents, Hermann von Helmholtz and his pupil Heinrich Hertz, (...) contributed significantly to the modernization of the conception of science. Paradigmatic for their common contribution to this development is the way in which they employed the concept of image. By considering the origin and the different meanings of this concept we may trace a line of development which begins with Helmholtz's original claim that a universally and forever valid theory provides a unique representation of nature. It continues with the realization that the status of scientific knowledge is capable of revision; and it arrives at Hertz's admission that a variety of theories over a domain of objects is possible, at least at times.

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)

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.

John Ellis McTaggart defended an idealistic view of time in the tradition of Hegel and Bradley. His famous paper makes two independent claims (McTaggart1908): First, time is a complex conception with two different logical roots. Second, time is unreal. To reject the second claim seems to commit to the first one, i.e., to a pluralistic account of time. We compare McTaggarts views to the most important concepts of time investigated in physics, neurobiology, and philosophical phenomenology. They indicate that a unique, (...) reductionist account of time is far from being plausible, even though too many conceptions of time may seem unsatisfactory from an ontological point of view.

How do opinion diversity and belief polarisation affect epistemic group decision-making, particularly if decisions must be made without delay and on the basis of permissive evidence? In an agent-based model, we track the consistency of group opinions aggregated through sentence-wise majority voting. Simulations on the model reveal that high opinion diversity, but not polarisation, incurs a significant inconsistency risk. These results indicate that epistemic group decisions based on permissive evidence can be particularly difficult for diverse groups. The results also improve (...) our understanding of what can reasonably be expected of expert groups, and where expert advice might have limits. (shrink)

Jean Baudrillards Kulturphilosophie läßt sich durch die Behauptung charakterisieren, daß die Medien in der modernen Kultur vorherrschend geworden sind. Seine These, die Medien hätten jeden Bezug zu einer von ihnen unabhängigen Realität verloren, haben zahlreiche Autorinnen und Autoren nihilistisch genannt. Das Zutreffende dieser Kennzeichnung verdankt sich im Wesentlichen einem eingeschränkten, auf das 19. Jahrhundert zurückweisenden Begriff des Nihilismus. Allerdings nimmt Baudrillard auf Phänomene Bezug, die er historisch später verortet und die sich ihrer Struktur nach kategorial von den Funktionen der Medien (...) im 19. Jahrhundert unterscheiden. Es gelingt ihm hierbei nicht, den allgemeinen Realitätsverlust, den er vor allem auf den wachsenden Einfluß von Wissenschaft und Technik im 20. Jahrhundert zurückführt, überzeugend nachzuweisen. -/- Als wolle er diesen Mangel beheben, führt Baudrillard in späteren Schriften weitere Struktureigenschaften der kulturellen Mediendominanz ein. Zu diesen Fortentwicklungen gehört die durch Medienmacht erzeugte „Transparenz“, die nicht zuletzt die restlose Durchsichtigkeit aller Zustände und Prozesse meint. Es ist dieses Merkmal, das Baudrillard 1981 selbst mit einem Nihilismusbegriff in Verbindung bringt. Der Nihilismus der Transparenz beansprucht, das spezifisch Neue der Sinnlosigkeit in zunehmend wissenschafts- und technikbestimmten Gesellschaften zu erfassen. Obwohl sich die Schwächen der Medientheorie in seiner Auffassung des Nihilismus reflektieren, gelingt es ihm, Phänomene der Nichtigkeit zu beschreiben, für die man gute Gründe hat anzunehmen, daß sie sich durch keinen Werte- oder Einstellungswandel mehr aufheben lassen. Um diese Einsicht zu begründen, muß man Baudrillards Medientheorie allerdings gleichsam vom Kopf auf die Füße stellen. Nicht auf einen evidenten, alles umfassenden Realitätsverlust, sondern umgekehrt auf einen Teil der vermutlichen Realitätsgehalte der Medien läßt sich die drohende Ausdehnung der Transparenz zurückführen.

The discourse on nihilism in the German-speaking world continues to take its orientation primarily from Friedrich Nietzsche’s understanding of nihilism as a historical movement of the decline of values. This means that the aspects of nihilism that are not tied to specific epochs and cultures are not accorded due importance (I). In order to make a reappraisal of nihilism that does justice to these objective contents, I will present a classification of types of nihilism and of arguments that support it. (...) The discussion of the typology of the principal meanings of nihilism points to a loss in relevance of conceptions that take their orientation from Nietzsche (II). The discussion of the arguments testifies to the importance of objective knowledge in the justification of nihilism (III). (shrink)

Nach einer kurzen Übersicht über das Leben und Werk von Helmholtz, diskutiere ich die drei Themenbereiche, die für die Beurteilung seines Verhältnisses zu Kant vornehmlich ins Gewicht fallen. Der erste Bereich bildet die Begründung des Energieerhaltungssatzes von 1847, den der späte Helmholtz selbst „durch Kant’s erkenntnistheoretische Ansichten […] beeinflusst“ gesehen hat. Während viele Interpreten diese Selbstauskunft für berechtigt halten, sehe ich in der Struktur der Begründung einen Ausdruck der gegensätzlichen Wissenschaftsauffassungen von Helmholtz und Kant. Als zweites gehe ich auf die (...) Rolle der Kausalität in der Wahrnehmungstheorie ein. In diesem Kontext bezieht sich Helmholtz erstmals und durchaus positiv explizit auf Kant. Seine Rede "Über das Sehen des Menschen" von 1855 zur Einweihung eines Kantdenkmals in Königsberg gilt als eines der Gründungsdokumente des Neukantianismus und spiegelt doch zugleich die tiefgreifenden Differenzen zwischen empiristischer und idealistischer Wissenschaftsphilosophie wider. Zeitlich wiederum nachfolgend steht die Begründung der nichteuklidischen Geometrien als dritter Bereich für die deutlichste Kritik an Kants transzendentaler Begründung der Wissenschaft. Sie ist zugleich wohl auch Helmholtz’ bekanntester Beitrag zur Hypothetisierung der Wissenschaftssauffassung. -/- der Gründungsdokumente des Neukantianismus und spiegelt doch zugleich die tiefgreifenden Differenzen zwischen empiristischer und idealistischer Wissenschaftsphilosophie wider. Zeitlich wiederum nachfolgend steht die Begründung der nichteuklidischen Geometrien als dritter Bereich für die deutlichste Kritik an Kants transzendentaler Begründung der Wissenschaft.

Dem Werk von Hermann von Helmholtz wird gemeinhin ein maßgeblicher Stellenwert bei der Begründung der neukantianischen Bewegung im 19. Jahrhundert beigemessen. Wo diese Zuordnung Helmholtz’ positive Bezüge auf Immanuel Kant ohne hinreichende Kontextualisierung hervorhebt, läuft sie Gefahr, die Distanz zu übersehen, die zwischen den wissenschaftsphilosophischen Positionen von Helmholtz und Kant bestand. In meinem Beitrag gewinnt das Verhältnis von Helmholtz zu Kant erst seine Bedeutung vor dem Hintergrund ihrer konträren ontologischen und erkenntnistheoretischen Grundannahmen. Helmholtz betrachte ich als repräsentativen Vertreter einer szientistischen Wissenschaftsauffassung in der Naturforschung des 19. Jahrhunderts. Demgegenüber bietet Kant ein paradigmatisches Beispiel einer metaphysischen Wissenschaftsbegründung. Im Gegensatz zu Kant beschränkt Helmholtz seinen Ausgangspunkt nicht auf erfahrungsfreie Prinzipien, sondern entwickelt und stützt seine Begründung des Geltungsanspruches der wissenschaftlichen Erkenntnis auf forschungsbewährte Theorien und Experimente. Eine Differenz zwischen den beiden Positionen findet sich ebenfalls in den Strukturen der jeweils vertretenen Naturkonzeptionen. Führt Kants dynamischer Mechanismus alle Eigenschaften der Materie auf Kräfte zurück, so geht Helmholtz von einer Dualität von Kraft und Materie aus. (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)

In recent decades, several authors have claimed that an epoch-making change in the development of science is taking place. A closer examination of this claim shows that these authors take different – and problematic – concepts of an epochal break as their points of departure. In order to facilitate an evaluation of the current development of science, I would like to propose a concept of an epochal change according to which it is not necessarily a discontinuous process that typically begins (...) in a subarea of the sciences, has far-reaching consequences for the entire system of the sciences, and can be observed by contemporaries as early as during its initial phase. Taking this concept as my point of departure, I discuss various candidates for the status of an epochal transformation in the recent development of the sciences. Although there are sound reasons to doubt that an epochal break is currently taking place, one must concede that the sciences are probably in a profound transformation, which could unfold in various directions, perhaps even leading to epoch-making new characterizations of the sciences.

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.).

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.

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)

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.

Definition, conditions and bearers of being a person - three philosophical aporias. -/- In this article I examine the philosophical question of how to define the concept of the person in a non-arbitrary way, how to find out the determining conditions of being a person and how to enumerate the bearers of being a person. I come to the conclusion that the question of a non-arbitrary definition, of the essential conditions and of the bearers of being a person has not (...) yet been clarified; it is not sufficiently clear what we actually mean or should mean by "person" - beyond conventions, disciplinary boundaries and doctrines. This results in three philosophical aporias of the concept of the person. (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.

God's necessary existence makes sense. Attempt at a transcendental modal proof. - In this essay I outline a novel three-stage proof of God's necessary existence using transcendental and deductive methods. In the first step of the proof, by retorsion, it is proved that there is at least one sentence that is necessary and inescapable. In the second step, the inescapability of the modal logic supposed in the proof is shown. This step also contains a new argument in favour of epistemic (...) anti-realism. The third step finally proves the necessary existence of the person who proves. The proof thus refers to the subject, the object, and the method of this proof itself. (shrink)

Autologos. A dialogue on fundamental logic. - In this dialogue of three dialogue partners, an attempt is made to prove the logical prerequisites of any meaningful dialogue by using transcendental arguments. Among these inescapable logical premises are a semantics as strong as that of modal logic S5, and an epistemic anti-realism.

Is knowledge-that a species of knowledge-how? - How is knowledge-how related to knowledge-that? Three possible answers are: (A1) intellectualism: knowledge-how is a subspecies of knowledge-that. (A2) Rylean account: knowledge-how and knowledge-that are completely distinct. (A3) anti-intellectualism: knowledge-that is a subspecies of knowledge-how. In this essay I present a new anti-intellectualist reductio argument that shows that answer A3 is true: knowledge-that is a subspecies of knowledge-how.

Forms of justification. On the structure and scope of self-refutation arguments in Plato, Cicero and Apel. - In this essay, the structure and scope of transcendental types of argumentation are analyzed, compared and criticized on the basis of the reception of two antiskeptical types of reasoning in ancient philosophy (Plato, Parmenides 135b-c; Cicero, Lucullus § 28) by a contemporary philosophical author (Karl-Otto Apel). Plato puts forward a transcendental argument for the inevitability of a final knowledge. Cicero argues that a principle (...) of fallibilism occurring with universal claim contradicts itself. In Karl-Otto Apel's transcendental pragmatic variant of philosophy, the two types of self-refutation arguments developed in Plato's and Cicero's dialogues are brought together into a single argumentation.

How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.

"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)

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)

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)
