The present debate in legal theory is dominated by an unfruitful schism. On the one hand, analytical theories are concerned with the positivity of law, running the risk of missing the law's relation to society. On the other hand, sociological approaches analyze all sorts of social interactions of law, but have developed no conceptual tools to do justice to the autonomy of law. The theory of autopoiesis offers law a chance of getting round the falsely posed alternative between an autonomous (...) rule system or a socially conditioned decision-making process. It is a theory of law that sees the law's autonomy in the self-reproduction of a communication network and understands its relation to society as interference with other autonomous communication networks. Building on the ideas of Humberto Maturana, Heinz von Foerster and Niklas Luhmann, Gunther Teubner uses the concepts of self-organization and autopoiesis to develop a concept of law as a hypercyclically closed social system. This book will stand as a landmark in legal theory and become a standard point of departure in the sociology of law. (shrink)

The aim of this article is to contribute to a better understanding of Frege’s views on semantics and metatheory by looking at his take on several themes in nineteenth century geometry that were significant for the development of modern model-theoretic semantics. I will focus on three issues in which a central semantic idea, the idea of reinterpreting non-logical terms, gradually came to play a substantial role: the introduction of elements at infinity in projective geometry; the study of transfer principles, especially (...) the principle of duality; and the use of counterexamples in independence arguments. Based on a discussion of these issues and how nineteenth century geometers reflected about them, I will then look into Frege’s take on these matters. I conclude with a discussion of Frege’s views and what they entail for the debate about his stance towards semantics and metatheory more generally. (shrink)

Mit dem vorliegenden Buch wird eine erkenntnistheoretische Fundierung f r eine empirische Rechtswissenschaft und f r eine ihr ad quate Methode angeboten. Im Mittelpunkt steht eine grundlegende Untersuchung des Verh ltnisses von Sein und Sollen. Veranschaulicht durch eine kritische Auseinandersetzung mit den tragenden Gedanken der reinen Rechtslehre Hans Kelsens und mit ihrem geistesgeschichtlichen Hintergrund, dem bisher noch keine geb hrende Beachtung zuteil geworden ist, entwickelt der Verfasser theoretische Grundpositionen f r eine dem positiven Recht und seiner sozial-kulturellen Erheblichkeit angemessene Rechtserkenntnislehre (...) und Rechtstheorie. Diese gr nden sich auf die transzendentale Logik Immanuel Kants. Der Verfasser, Doyen der sterreichischen Staatsrechtslehre und Leitfigur vieler Juristengenerationen, legt mit diesem Buch das Ergebnis seiner jahrzehntelangen Befassung mit Fragen der Rechtstheorie und der Rechtserkenntnislehre vor. Er kommt zum Ergebnis, da die Rechtswissenschaft die Verkn pfung von Sein und Sollen in Rechtserzeugung, Rechtsbestand und Rechtsverwirklichung erkenntnistheoretisch, rechtstheoretisch und methodologisch beachten mu, will sie das Recht als ein komplexes Kulturph nomen gegenstandsgerecht begreifen. Eine rein normative Rechtslehre versperrt den erkenntnism igen Zugang zum Wesen des positiven Rechts, das nicht nur als ein formales Sollen, sondern auch als eine seinsgebundene wert- und zweckhafte Sinneinheit in Form und Inhalt erkannt, beschrieben, erkl rt, verstehend gedeutet und seinen Eigenarten gem dargestellt werden mu.

Der Begriff der axiomatischen Basis einer physikalischen Theorie wurde in [1] eingeführt. Die dort gegebene Definition ist zu eng verglichen mit dem, was in der theoretischen Physik angestrebt wird und z. B. für die Quantenmechanik in [2] und [3] durchgeführt ist. Die in dieser Arbeit angegebene, neue Definition einer axiomatischen Basis beschreibt das tatsächliche Vorgehen der theoretischen Physik methodisch besser. Die neue Definition erlaubt es auch, die Untersuchungen über physikalische Begriffe insofern gegenüber [1] zu verbessern, als es möglich ist, sauber (...) zwischen "theoretischen Hilfsbegriffen" und "theoretischen Begriffen" zu unterscheiden. Es läßt sich genauer definieren, was man unter "physikalisch interpretierbaren" Gesetzen verstehen will. Entgegen mancher Meinung wird die Vermutung aufgestellt, daß man jede physikalische Theorie mit "physikalisch interpretierbaren" Gesetzen, d. h. ohne theoretische Hilfsbegriffe formulieren kann.

Applied sociology will be understood in the following discussion as a unique and original form of sociology; i.e., in its logic and practice distinguished from traditional sociology it is understood as an explanatory body of knowledge and an intellectual discourse about intentional/purposeful social action and behavior. The application of sociology proper to such substantive fields as family, art, law and sport, commonly called applied sociology, which reproduce the body of sociological knowledge just a second time, is not part of such (...) understanding. Applied sociology in its original sense has its own logic in which purpose, implementation and the process of social-problem solution are crucial. It will in the end lead to an applied action or implementation theory. It is, to paraphrase Lazarsfeld, the methodology of “sociology in action” (1960). (shrink)

This contribution demonstrates that the development and growth of plants depends on the success of complex communication processes. These communication processes are primarily sign-mediated interactions and are not simply an mechanical exchange of ‘information’, as that term has come to be understood (or misunderstood) in science. Rather, such interactions as I will be describing here involve the active coordination and organisation of a great variety of different behavioural patterns — all of which must be mediated by signs. Thus proposed, a (...) biosemiotics of plant communication investigates communicationprocesses both within and among the cells, tissues, and organs of plants as sign-mediated interactions which follow (1) combinatorial (syntactic), (2) context-sensitive (pragmatic) and (3) content-specific (semantic) levels of rules. As will be seen in the cases under investigation, the context of interactionsin which a plant organism is interwoven determines the content arrangement of its response behaviour. And as exemplified by the multiply semiotic roles playedby the plant hormone auxin that I will discuss below, this means that a molecule type of identical chemical structure may function in the instantiation of differentmeanings (semantics) that are determined by the different contexts (pragmatics) in which this sign is used.

I present an argument for the existence of nonconceptual states. A nonconceptual state is an intentional state which does not require the bearer to possess all requisite concepts in order to represent the state. I frame the debate by outlining two constraints that an argument for nonconceptuality should meet. First, successful argument must present a platitude of concepts and illustrate that there are intentional states which both actually violate this platitude and explain behavior independently of conceptual states. This ensures that (...) the notion of nonconceptuality established by the argument will have a significant part in the explanatory arsenal of the intentional psychologist. Secondly, I formulate a platitude of concepts based on the intuition that an individual can only legitimately be held responsible for behavior caused by conceptual states. After qualifying the platitude, I argue that emotional states actually violate the platitude and meet the necessary constraints. Finally, I defend my argument against two challenges: one which denies that the empirical constraint has been met and the other which denies that the robustness constraint has been met. I conclude my discussion with some general remarks on the nature of nonconceptual representation. (shrink)

Manfred Eigen extended Erwin Schroedinger’s concept of “life is physics and chemistry” through the introduction of information theory and cybernetic systems theory into “life is physics and chemistry and information.” Based on this assumption, Eigen developed the concepts of quasispecies and hypercycles, which have been dominant in molecular biology and virology ever since. He insisted that the genetic code is not just used metaphorically: it represents a real natural language.However, the basics of scientific knowledge changed dramatically within the second half (...) of the 20th century.Unfortunately, Eigen ignored the results of the philosophy of science discourse on essential features of natural languages and codes: a natural language or code emerges from populations of living agents that communicate. This contribution will look at some of the highlights of this historical development and the results relevant for biological theories about life. (shrink)

The evidence that L2 learners have full access to UG is not convincing.

(2) The claim that L2 acquisition takes place under the constraints imposed by universal principles lacks empirical support.

Chloride channels are probably found in every cell, from bacteria to mammals. Their physiological tasks range from cell volume regulation to stabilization of the membrane potential, signal transduction, transepithelial transport and acidification of intracellular organelles. These different functions require the presence of many distinct chloride channels, which are differentially expressed and regulated by various stimuli. These include various intracellular messengers (like calcium and cyclic AMP), pH, extracellular ligands and transmembrane voltage. Three major structural classes of chloride channels are known to (...) date, but there may be others not yet identified. After an overview of the general functions of chloride channels, this review will focus on these cloned chloride channels: the CLC chloride channel family, which includes voltage‐gated chloride channels, and the cystic fibrosis transmembrane regulator (CFTR), which performs other functions in addition to being a chloride channel. Finally, a short section deals with GABA and glycine receptors. Diseases resulting from chloride channel defects will be specially emphasized, together with the somewhat limited information about how these proteins work at the molecular level. (shrink)

Background In nursing homes, residents’ relatives represent important sources of support for nurses. However, in the heightened stress of emergency situations, interaction between nurses and relatives can raise ethical challenges. Research objectives The present analysis aimed at elaborating a typology of nurses’ experience of ethical support and challenges in their interaction with relatives in emergency situations. Research design Thirty-three semi-structured interviews and six focus groups were conducted with nurses from different nursing homes in Germany. Data were analysed according to Mayring’s (...) method of qualitative content analysis. Participants and research context Participants were licensed nurses working in nursing homes. Ethical considerations Ethical approval was granted by Ostfalia University of Applied Sciences (02.07.2020) and the Ethics Committee of Hannover Medical School (Nr. 8866_BO_K_2020; 27.01.2020). Interviewees were anonymised and focus group were pseudonymised during transcription. All participants provided written consent. Findings/results In emergency situations, relatives can represent important sources of support for nurses. However, they may also give rise to different challenges, relating to four ethical conflicts: (1) the challenge of meeting the information needs of relatives while providing appropriate care to all residents; (2) the challenge of managing relatives’ demands for hospitalisation when hospitalisation is not deemed necessary by nurses; (3) the challenge of managing relatives’ demands for lifesaving treatment when such treatment contradicts the will of the resident; and (4) the challenge of attempting to initiate hospitalisation when relatives oppose this course of action. Several external factors make these conflicts especially challenging for nurses: fear of legal consequences, a low staffing ratio, and a lack of qualified nursing staff. Conclusions Conflict between nurses and relatives typically revolves around hospitalisation and the initiation of lifesaving treatment. Whether nurses perceive interaction with relatives as supportive or conflictual essentially depends on the quality of the relationship, which may be negatively influenced by a number of external factors.

The philosopher, writer and technology critic Günther Anders, né Stern (1902–1992), occasionally referred to his own thinking as “occasional philosophy”. In order to reconstruct this mode of thought, which is also an essential key to understanding Anders, I will refer to a previously unpublished typescript of the same name from his literary estate. This reconstruction will be based on three theses: From the outset, Anders’ work is characterised by a preoccupation with questions of method. Secondly, the tools of occasional philosophy (...) can be found not only in his philosophical writings, but above all in his reflections on art, literature and photomontage. Thirdly, the prima vista eclectic and anti-systematic method is a logical reaction to the fundamentally changed conditions of philosophising in a (post-)modern, technologised society. (shrink)

Artificial Intelligence as a buzzword and a technological development is presently cast as the ultimate ‘game changer’ for economy and society; a technology of which we cannot be the master, but which nonetheless will have a pervasive influence on human life. The fast pace with which the multi-billion dollar AI industry advances toward the creation of human-level intelligence is accompanied by an increasingly exaggerated chorus of the ‘incredible miracle’, or the ‘incredible horror’, intelligent machines will constitute for humanity, as the (...) human is gradually replaced by a technologically superior proxy, destined to be configured as a functional (data) component at best, a relic at worst. More than half a century ago, Günther Anders sketched out this path toward technological obsolescence, and his work on ‘Promethean shame’ and ‘Promethean discrepancy’ provides an invaluable means with which to recognise and understand the relationship of the modern human to his/her technological products. In this article, I draw on Anders’s writings to unpack and unsettle contemporary narratives of our relation to AI, with a view toward refocusing attention on the responsibilities we bear in producing such immersive technologies. With Anders, I suggest that we must exercise and develop moral imagination so that the human capacity for moral responsibility does not atrophy in our technologically mediated future. (shrink)

The essay reconstructs Gotthard Günther’s interpretation of Fichte’s philosophy. The starting point of this reconstruction are Günther’s investigations into a formal logic of reflection and their approaches in German idealism. Particular attention is given to the volitional aspect of Günther’s logic. According to Günther, Fichte is the first philosopher clearly to see and to explain the duality of reflection posed by Kant as a problem. According to Günther, the second important contribution of Fichte is the insight that thinking in the (...) double reflection is no longer a passive reflection but an action. Despite these two starting points, Fichte does not transcend the framework of classical thought. This is because of his identification of thinking and acting or willing. Their separation is finally accomplished only in Schelling’s late philosophy, in which a change of theme from being to action takes place. This allows the separation of form and content in the double reflection as well. Günther’s introduction of the will into logic is based on the distinction between logical value and ontological location. The latter is, as a floating exchange relation, an indeterminate vacancy which can be occupied by logical values. This assignment is accomplished, which represents Günther’s transference of the Fichtean theory of positing to the theory of trans-classical technique, no longer by thinking, but by way of technical construction. Der Aufsatz rekonstruiert Gotthard Günthers Interpretation der Philosophie Fichtes. Ausgangspunkt dieser Rekonstruktion sind Günthers Untersuchungen zu einer formalen Logik der Reflexion und deren Ansätzen im deutschen Idealismus. Ein besonderes Augenmerk gilt dabei dem volitiven Aspekt von Günthers Logik. Günther zufolge ist Fichte der erste Philosoph, der die von Kant als Problem aufgeworfene Doppelstufigkeit der Reflexion klar gesehen und expliziert hat. Der zweite bedeutsame Beitrag Fichtes besteht nach Günther in der Einsicht, dass in der doppelten Reflexion das Denken nicht mehr passive Widerspiegelung, sondern Handlung ist. Trotz dieser beiden Ansatzpunkte verlässt Fichte den Rahmen des klassischen Denkens aufgrund seiner Identifizierung von Denken und Handeln bzw. Wollen nicht. Deren Trennung wird erst in Schellings Spätphilosophie vorgenommen, in der sich ein Themawechsel vom Sein zur Handlung vollzieht. Dies ermöglicht die Trennung von Form und Inhalt auch in der doppelten Reflexion. Günthers Introduktion des Willens in die Logik erfolgt anhand der Unterscheidung von logischem Wert und ontologischem Ort. Letzterer ist als schwebendes Umtauschverhältnis eine unbestimmte Leerstelle, die durch logische Werte besetzt werden kann. Diese Wertbesetzung erfolgt, und das ist Günthers Übertragung der Fichteschen Theorie des Setzens auf die Theorie trans-klassischer Technik, nicht mehr durch das Denken, sondern auf dem Wege technischer Konstruktion.

Following media-theoretical studies that have characterized digitization as a process of all-encompassing cybernetization, this paper will examine the timely and critical potential of Günther Anders’s oeuvre vis-à-vis the ever-increasing power of cybernetic devices and networks. Anders has witnessed and negotiated the process of cybernetization from its very beginning, having criticized its tendency to automate and expand, as well as its circular logic and ‘integral power’, including disruptive consequences for the constitution of the political and the social. In this vein, Anders’s (...) works, particularly his magnum opus Die Antiquiertheit des Menschen [The Obsolescence of Man], sheds new light on the technologically organized milieus of the contemporary digital regime and also highlights a new form of cybernetic ‘conformism’. The goal of the essay is therefore, not only to emphasize the contemporary nature of Anders’s thought but also to use it to frame a critique of current neo-technocratic and, ultimately, post-political concepts, such as ‘algorithmic regulation’, ‘smart states’, ‘direct technocracy’, and ‘government as platform’. This essay argues that cybernetic capitalism is causing what Anders terms ‘ Unfestgelegtheit’ to disappear; that is, we are losing the originary possibility of technologically (re-)structuring our world in alternative ways, particularly given the determinist character of current technologies.

In lieu of an abstract, here is a brief excerpt of the content:Dei Filius IV:On the Development of DogmaAndrew MeszarosIntroductionHistorically, it is indisputable that the intention of the latter part of chapter 4 of Dei Filius was to restate the substantial immutability of the deposit of faith, not for the sake of rejecting doctrinal development, but for the sake of establishing parameters for a certain profectus fidei—progress or development in the faith—which no Catholic theologian doubted, not even nineteenth-century neo-Scholastics. Then-contemporary (...) (e.g., John Henry Newman and the Tübingen school) and subsequent (e.g., Yves Congar and Henri de Lubac) theologians' theories that were more thoroughly worked out presupposed this immutability.The argument here is simple: Dei Filius's teaching on the immutability of dogma not only did serve as the necessary foundation for any sound (i.e., Catholic) theory of doctrinal development, but continues to do so. While the teaching of Dei Filius itself is limited and incomplete, it is essential. Furthermore, its key feature of dogmatic immutability is not compromised by even the most dramatic of doctrinal developments.To establish the ongoing relevance of Dei Filius for contemporary discussions on doctrinal development, I will first draw out certain key similarities between the nineteenth-century, modernist, and contemporary contexts. This will be followed by a presentation of the relevant portions of Dei Filius. Finally, in the longest section, I will discuss what is at stake in the teaching of Dei Filius and offer some different examples of how doctrines develop in ways that uphold the fundamental-theological principle laid out [End Page 909] in Dei Filius: namely, that all doctrinal development is homogenous with, or in continuity with, the deposit of faith.Anton Günther and Theology TodayWe can identify two major factors that led to the Vatican Council having to address dogmatic development. The first, and perhaps most important, factor is the implication that Anton Günther's (1783–1863) understanding of faith and reason had on dogma and its immutability. The second factor is simply the fact that, in the midst of these pervasive philosophical and theological disputes over faith and reason, Pius IX not only managed to define the Immaculate Conception as dogma, but did so by papal definition: the 1854 definition was the freshest example of what would later be defined in 1870.1 A brief examination of the thought of Günther will help us better understand why the paragraph on development (i.e., the immutability and progress of dogma) pertains to the faith–reason relationship and, hence, appears in the fourth chapter. 2Günther's major concern is a noble one: namely, to respond to the Kantian critique of supernatural religion. To do so, he sees it as necessary not only to defend rationally but also to explain rationally—according to the philosophical systems of Schelling and Hegel—Christian dogma. Günther is no brash and pure rationalist. He believes in the history of supernatural revelation. He acknowledges that reason alone could never discover supernaturally revealed truths; but, as a so-called semi-rationalist, he believes that, once made known to it, reason can then penetrate and, indeed, prove these revealed truths.3 [End Page 910]But if revealed mysteries are discoverable by human reason, then those same mysteries have to be interpreted in such a way that is, indeed, within the reach of reason using its proper resources.4 Not Scholasticism but German idealism—especially its category of self-consciousness—was Günther's vehicle for giving an account of the faith. Such a re-interpretation of Christian dogma according idealism's categories naturally alters the original understanding of that dogma. But for Günther, this reinterpretation is necessary if revelation is to be accessible to reason.So, for example, because modern psychology cannot make sense of a distinction between "person" and "nature" that is not coterminous, we must conclude, against Ephesus, that Christ is in fact a unity of two persons. Nor, for that matter, is the human person a composite of body and soul as defined by the Council of Vienne (1311–1312). Because God is self-conscious spirit, there is a process of trebling in God that tends toward... (shrink)

This paper presents and discusses a series of hybridization experiments carried out by Nils Herman Nilsson-Ehle between 1900 and 1907 at a plant breeding station in Svalöf, Sweden. Since the late 1880s, the Svalöf station had been renowned for its ‘scientific’ breeding methods, which basically consisted of an elaborate system of record-keeping through which the offspring of individual plants were traced over generations while being meticulously described. This record system corresponded to a certain breeding technique and certain theoretical convictions . (...) Inspired by Tschermack’s translation of Mendel’s Pisum-paper, Nilsson-Ehle began his experiments in 1900 and published a first, major synthesis of his findings in 1908. If one compares these experiments as documented in the breeding records, with their representations in print, one encounters discrepancies in terms of procedure and presentation of data. This can be explained by the fact that Nilsson-Ehle was obliged to follow the recording and breeding procedures institutionalised at Svalöf, and these procedures, grounded in a taxonomic discourse, left little room for Mendelian hybridisation experiments. The twists and turns that this story takes are analysed in terms of Bachelardian philosophy of science, where the ‘epistemological obstacle’ functions as a central, analytic category. In contrast to Bachelard, however, I will characterise these obstacles as being of an institutional, rather than mental, nature. Thus characterized, moreover, they turn out to have been prerequisites as much as barriers to scientific progress. (shrink)

This paper provides a translation of the introduction, titled ‘Account of the work’ Ratio operis, to the first edition of Genera plantarum, published in 1737 by the Swedish botanist Carl Linnaeus. The text derives its significance from the fact that it is the only published text in which Linnaeus engaged in an explicit discussion of his taxonomic method. Most importantly, it shows that Linnaeus was clearly aware that a classification of what he called ‘natural genera’ could not be achieved by (...) a top-down approach of logical division, but had to rely on inductive, bottom-up procedures. The translation is supplemented by explanatory notes. (shrink)

The historiography of race is usually framed by two discontinuities: the invention of race by European naturalists and anthropologists, marked by Carl Linnaeus’s Systema naturae and the demise of racial typologies after World War II in favor of population-based studies of human diversity. This framing serves a similar function as the quotation marks that almost invariably surround the term. “Race” is placed outside of rational discourse as a residue of outdated essentialist and hierarchical thinking. I will throw doubt on this (...) underlying assumption, not in order to re-legitimate race but in order to understand better why race has been, and continues to be, such a politically powerful and explosive concept.

Historians and philosophers of science have interpreted the taxonomic theory of Carl Linnaeus as an ‘essentialist’, ‘Aristotelian’, or even ‘scholastic’ one. This interpretation is flatly contradicted by what Linnaeus himself had to say about taxonomy in Systema naturae , Fundamenta botanica and Genera plantarum . This paper straightens out some of the more basic misinterpretations by showing that: Linnaeus’s species concept took account of reproductive relations among organisms and was therefore not metaphysical, but biological; Linnaeus did not favour classification by (...) logical division, but criticized it for necessarily failing to represent what he called ‘natural’ genera; Linnaeus’s definitions of ‘natural’ genera and species were not essentialist, but descriptive and polytypic; Linnaeus’s method in establishing ‘natural’ definitions was not deductive, but consisted in an inductive, bottom-up procedure of comparing concrete specimens. The conclusion will discuss the fragmentary and provisional nature of Linnaeus’s ‘natural method’. I will argue in particular that Linnaeus opted for inductive strategies not on abstract epistemological grounds, but in order to confer stability and continuity to the explorative practices of contemporary natural history.

Gottlob Frege’s Grundgesetze der Arithmetik (Basic Laws of Arithmetic, Vol. I/II; 1893/1903) is a modern classic. Since the 1930s it has belonged to an exclusive class of only eleven works in the history of symbolic logic, which contain the ‘first appearance of a new idea of fundamental importance’ [Church, 1936, p. 122], and its author is the only one whose other major works — Begriffsschrift (1879) and Die Grundlagen der Arithmetik (1884) — also belong to this distinguished group. Together with (...) the seminal paper ‘Über Sinn und Bedeutung’ these three monographs represent the essential contributions to one of the most fascinating foundational projects in mathematics, then and now. For decades Frege struggled with the question, ‘how are we to apprehend logical objects, in particular, the numbers? What justifies us in acknowledging numbers as objects?’ [Frege, 2013, ‘Afterword’, p. 265]. His favourite answer, for a long time, was that arithmetic is a complex branch of logic. But since there is no logicism without logic, Frege started in Begriffsschrift with the invention of a nearly perfect formalization of higher-order classical predicate logic. To discover how far we can get in arithmetic by analytic means alone, it was even necessary to clarify the semantic character of the concept of number. This was done in a marvellous way by Frege five years later, in Grundlagen. The next step was nothing less than the complete execution of his logicist project, a monumental undertaking; and it is well known that here Frege failed, due to Russell’s derivation of the antinomy in 1902. But, despite the contradiction, Grundgesetze contains Frege’s legacy to logicism, which became more and more attractive. (shrink)

The cell is not only the structural, physiological, and developmental unit of life, but also the reproductive one. So far, however, this aspect of the cell has received little attention from historians and philosophers of biology. I will argue that cell theory had far-reaching consequences for how biologists conceptualized the reproductive relationships between germs and adult organisms. Cell theory, as formulated by Theodor Schwann in 1839, implied that this relationship was a specific and lawful one, that is, that germs of (...) a certain kind, all else being equal, would produce adult organisms of the same kind, and vice versa. Questions of preformation and epigenesis took on a new meaning under this presupposition. The question then became one of whether cells could be considered as autonomous agents producing adult organisms of a given species, or whether they were the product of external, organizing forces and thus only a stage in the development of the whole organism. This question became an important issue for nineteenth-century biology. As I will demonstrate, it was the view of cells as autonomous agents which helped both Charles Darwin and Gregor Mendel to think of inheritance as a lawful process. (shrink)

Im 20. Jahrhundert sind Zweifel an normativ hoch aufgeladenen Unterscheidungen aufgekommen, wie zwischen Mensch und Tier oder zwischen Frau und Mann, und dies hat die Dringlichkeit gesteigert, nicht nur uber bestimmte Unterscheidungen zu streiten, sondern sich auf die Arten und Weisen unseres Unterscheidens selbst zu richten. Unsere Praxis des Unterscheidens lasst sich nicht als ganze uberblicken, sondern nur exemplarisch an bestimmten Unterscheidungsvollzugen reflektieren. Dies geschieht in der vorliegenden Studie am Beispiel der Unterscheidung zwischen Wunsch und Wille. Diese Unterscheidung betrifft (...) unser Selbstverstandnis als Handelnde und sie verweist auf die Erfahrung der Diskrepanz zwischen dem, was wir uns vornehmen und gerne tun wurden, und dem, was wir tatsachlich tun.

Prompted by recent recognitions of the omnipresence of horizontal gene transfer among microbial species and the associated emphasis on exchange, rather than isolation, as the driving force of evolution, this essay will reflect on hybridization as one of the central concerns of nineteenth-century biology. I will argue that an emphasis on horizontal exchange was already endorsed by ‘biology’ when it came into being around 1800 and was brought to full fruition with the emergence of genetics in 1900. The true revolution (...) in nineteenth-century life sciences, I maintain, consisted in a fundamental shift in ontology, which eroded the boundaries between individual and species, and allowed biologists to move up and down the scale of organic complexity. Life became a property extending both ‘downwards’, to the parts that organisms were composed of, as well as ‘upwards’, to the collective entities constituted by the relations of exchange and interaction that organisms engage in to reproduce. This mode of thinking was crystallized by Gregor Mendel and consolidated in the late nineteenth-century conjunction of biochemistry, microbiology and breeding in agro-industrial settings. This conjunction and its implications are especially exemplified by Wilhelm Johannsen’s and Martinus Beijerinck’s work on pure lines and cultures. An understanding of the subsequent constraints imposed by the evolutionary synthesis of the twentieth century on models of genetic systems may require us to rethink the history of biology and displace Darwin’s theory of natural selection from that history’s centre.

Abstract.Klaus Günther's (1988) book developed the distinction between two kinds of discourse, the foundation discourse and the application discourse. In an article (Günther 1989a) following the publication of the book, he used this basic distinction as the starting point for a criticism of the special case‐thesis as defended by Robert Alexy (1978, 32ff., 263ff.; Alexy 1989, 16ff., 213ff.). The aim of this article is to criticize this criticism in its turn and to show that the special case‐thesis does not need (...) the reformulation which Günther proposes. It should be clear from the outset that this concerns an internal discussion in the field of discourse theory; certain discourse‐theoretical premises are taken for granted. In order to understand Giinther's criticism I will first give a brief account of the distinction he has made. (shrink)
