Classically, an osculating circle at a point of a planar curve is introduced technically, often with formula giving its radius and the coordinates of its center. In this note, we propose a new and intuitive definition of this concept: among all the circles which have, on the considered point, the same tangent as the studied curve and thus seem equal to the curve through a microscope, the osculating circle is this that seems equal to the curve (...) through a microscope within microscope.

One of the major purposes of this article is to show that friendship was one of Nietzsche's central concerns and that he shared Aristotle's belief that it takes higher and lower forms. Yet Nietzsche's interest in friendship is overlooked in much of the secondary literature. An important reason for this is that this interest is most evident in the works of his middle period, and these tend to be neglected in commentaries on Nietzsche. In the works of the middle period, (...) Nietzsche suggests that there is a close connection between friendship and selfhood, contending that an individual's friendships reflect something about his or her identity. Following Aristotle, he believes that friendship can make a significant contribution to self-knowledge and self-improvement, which are both closely associated with his notion of self-overcoming. Nietzsche encourages individuals to adopt an aesthetic approach to the self: they should refashion themselves by consolidating their strengths, minimising their weaknesses and developing themselves in new directions. The works of the middle period suggest, however, that not only can friendship foster self-overcoming, but that the talent for friendship is one of the marks of a higher human being. Recognising this requires some reconsideration of Nietzsche's putative individualism and the belief that he holds great individuals to be utterly independent and indifferent to the judgements of others. It also requires a revision of the common interpretation that he is unremittingly sceptical about pity and other forms of fellow-feeling. Yet while Nietzsche generalises about friendship in the works of the middle period and contrasts its superior and inferior forms, he remains sensitive to its particularity. He never adopts a wholly formulaic approach to this relationship, but recognises that difference and responsiveness to particularity are among its central characteristics. (shrink)

This abridged and revised edition of the original book (Springer-Verlag Vienna, 2001) offers the only comprehensive history and documentation of the Vienna Circle based on new sources with an innovative historiographical approach to the study of science. With reference to previously unpublished archival material and more recent literature, it refutes a number of widespread clichés about "neo-positivism" or "logical positivism". Following some insights on the relation between the history of science and the philosophy of science, the book offers an (...) accessible introduction to the complex subject of "the rise of scientific philosophy" in its socio-cultural background and European philosophical networks till the forced migration in the Anglo-Saxon world. The first part of the book focuses on the origins of Logical Empiricism before World War I and the development of the Vienna Circle in "Red Vienna" (with the "Verein Ernst Mach"), its fate during Austro-Fascism (Schlick's murder 1936) and its final expulsion by National-Socialism beginning with the "Anschluss" in 1938. It analyses the dynamics of the Schlick-Circle in the intellectual context of "late enlightenment" including the minutes of the meetings from 1930 on for the first time published and presents an extensive description of the meetings and international Unity of Science conferences between 1929 and 1941. The chapters introduce the leading philosophers of the Schlick Circle (e.g., Hans Hahn, Otto Neurath, Rudolf Carnap, Philipp Frank, Felix Kaufmann, Edgar Zilsel) and describe the conflicting interaction between Moritz Schlick and Otto Neurath, the long term communication between Moritz Schlick, Friedrich Waismann and Ludwig Wittgenstein, as well as between the Vienna Circle with Heinrich Gomperz and Karl Popper. In addition, Karl Menger's "Mathematical Colloquium" with Kurt Gödel is presented as a parallel movement. The final chapter of this section describes the demise of the Vienna Circle and the forced exodus of scientists and intellectuals from Austria.The second part of the book includes a bio-bibliographical documentation of the Vienna Circle members and for the first time of the assassination of Moritz Schlick in 1936, followed by an appendix comprising an extensive list of sources and literature.

The paper is devoted to the presentation and analysis of the philosophical views concerning logic and mathematics of the leading members of Cracow Circle, i.e., of Jan Salamucha, Jan Franciszek Drewnowski and Józef Maria Bocheński. Their views on the problem of possible applicability of logical tools in metaphysical and theological researches is also discussed.

Safe-by-Design is an approach to engineering that aims to integrate the value of safety in the design and development of new technologies. It does so by integrating knowledge of potential dangers in the design process and developing methods to design undesirable effects out of the innovation. Recent discussions have highlighted several challenges in conceptualizing safety and integrating the value into the design process. Therefore, some have argued to design for the _responsibility_ for safety, instead of for safety itself. However, this (...) idea has not been developed further. In this article, we develop an approach to Safe-by-Design, grounded in care ethics, which builds on the idea of designing for responsibility and can deal with the complexity that is inherent to the conceptualization of safety. We describe five ways in which care ethics contributes to the conceptualization of Safe-by-Design: (1) It suggests the development of ‘circles of care’ in which stakeholders share the responsibility for safety; (2) it recognizes the importance of considering safety as something that is situated in the surroundings of a technology, instead of as a property of the technology itself; (3) it acknowledges that achieving safety is labour that requires an ongoing commitment; (4) it emphasizes that the way in which we relate to technology impacts its safety; and (5) it recognizes the role of emotions in assessing safety. All these elements combined lead to a broader understanding of safety and a philosophically more substantial and practically more appealing conceptualization of Safe-by-Design. (shrink)

The book aims at the logical and conceptual analysis of philosophical problems in logic, analysis of mind and knowledge. In presents several internal connections between logical, practical and ethical reasoning and getting individual and collective knowledge. The author connects conceptual analysis, some modal logical arguments and some Wittgensteinian motives in the analysis of vagueness, process logic, skepticism, practical reasoning and getting knowledge.

Hermeneutic studies of science locate a circle at the heart of scientific practice: scientists only gain knowledge of what they, in some sense, already know. This may seem to threaten the rational validity of science, but one can argue that this circle is a virtuous rather than a vicious one. A virtuous circle is one in which research conclusions are already present in the premises, but only in an indeterminate and underdeveloped way. In order to defend the (...) validity of science, the hermeneuticist must describe a method by which a vague and confused initial knowledge of nature gets transformed into a clear and determinate knowledge of nature. I consider three such methods. The first is regressus demonstrativa, favoured by the physicians of Padua during the fifteenth and sixteenth centuries. The second is mathēsis, introduced by Martin Heidegger in his discussion of seventeenth-century science. The third is Denkstil, a key concept in Ludwik Fleck’s history of syphilology. I conclude by listing three desiderata for a hermeneutic science studies: that it be anti-metaphysical, historical, and sociological. --- Reprinted in: Erich Otto Graf, Martin Schmid & Johannes Fehr (eds.), Fleck and the Hermeneutics of Science (Collegium Helveticum Heft 14) (Zürich, 2016), pp. 85-93.

How can a business institution function as an ethical institution within a wider system if the context of the wider system is inherently unethical? If the primary goal of an institution, no matter how ethical it sets out to be, is to function successfully within a market system, how can it reconcile making a profit and keeping its ethical goals intact? While it has been argued that some ethical businesses do exist, e.g., Johnson and Johnson, the argument I would like (...) to put forth is that no matter how ethical a business institution is, or how ethical its goals are, its capacity to act in an ethical manner is restricted by the wider system in which it must operate, the market system. Unless there is a fundamental change in the notion of the market system itself, the capacity for individual businesses to act in an ethical manner will always be restricted. My argument is divided into two parts. The first part is to show the inherent bias towards unethical outcomes that is inherent in the market system. The second part is to suggest how to reorient the general economic framework in order to make ethical institutions more possible. The question then becomes, how to define economic behavior in terms other than competition for profit. (shrink)

This article compares the work of Jakob von Uexkull and Charles S. Peirce to elucidate two contrasting yet connected images of ecosemiotics. The intent is not simply to oppose their work, but to explore a tension which has implications for the ethical dimension of this emerging discipline. Uexkull’s functional cycle is associated with the image of a circle, which, while emphasizing the integration of organism and environment, is shown to invoke solipsism, and an overly deterministic depiction of ecological relations. (...) Peirce’s drawing of a labyrinth is taken to represent a maze, which, while exemplifying the evolutionary play of ecosystems, may entail a level of unpredictability that is catastrophically chaotic. The root of these diverging depictions is identified with the role of subjectivity in engendering semiotic relations in the work of both Uexkull and Peirce. Where the more regressive aspects of Uexkull’s theoretical biology are mitigated by a teleological interpretation of life’s underlying causality, orientating agency within Peirce’s work depends upon attention to the idea of the self in his philosophy of signs. In conclusion, Eduardo Kohn’s conception of an ‘ecology of selves’ is cited, and the status of the organism as a living symbol of its environment is reaffirmed. (shrink)

Different methods are available in clinical ethics consultation. In our experience as ethics consultants, certain individual methods have proven insufficient, and so we use a combination of methods. Based on these considerations, we first critically analyze the pros and cons of two well-known methods in the working field of clinical ethics, namely Beauchamp and Childress’s four-principle approach and Jonsen, Siegler, and Winslade’s four-box method. We then present the circle method, which we have used and refined during several clinical ethics (...) consultations in the hospital setting. (shrink)

We hypothesize that threat of dehydration provided selection pressure for the evolutionary emergence and persistence of the anterior communicating artery (ACoA – the inter‐arterial connection that completes the Circle of Willis) in early amniotes.The ACoA is a hemodynamically insignificant artery, but, as we argue in this paper, its privileged position outside the blood‐brain barrier gives it a crucial sensing function for the osmolarity of the blood against the background of the rest of the brain, which efficiently protects itself from (...) dehydration. Till now, the questions of why the ACoA evolved, and what its physiological function is, have remained unsatisfactorily answered. The traditional view—that the ACoA serves as a collateral source of vascularization in case of arterial stenosis—is anthropocentric, and not in accordance with principles of natural selection that apply more generally. Diseases underlying arterial stenosis are associated with aging and the human lifestyle, so this cannot explain why the ACoA formed hundreds of millions of years ago and persisted in amniotes to this day.The peculiar hemodynamic properties of the ACoA could be selected traits that allowed for more efficient forebrain detection of dehydration and complex behavioral responses to water loss, a major advantage in the survival of early amniotes. This hypothesis also explains insufficient hydration often seen in elderly humans. (shrink)

The Russian philosopher and cultural theorist Mikhail Bakhtin has traditionally been seen as the leading figure in the group of intellectuals known as the Bakhtin Circle. The writings of other members of the Circle are considered much less important than his work, while Bakhtin's achievement has been exaggerated in proportion to the downgrading of the thinkers with whom he associated in the 1920s. This volume, which includes new translations and studies of the work of the most important members (...) of the Circle, sets out to correct the distortions in the established representations of its activity. The original contributions to literary and linguistic theory made by Valentin Voloshinov and Pavel Medvedev (but frequently credited to Bakhtin) are assessed, and the distinctiveness of their approaches is highlighted.

What is ethics? Where do moral standards come from? Are they based on emotions, reason, or some innate sense of right and wrong? For many scientists, the key lies entirely in biology---especially in Darwinian theories of evolution and self-preservation. But if evolution is a struggle for survival, why are we still capable of altruism? In his classic study The Expanding Circle, Peter Singer argues that altruism began as a genetically based drive to protect one's kin and community members but (...) has developed into a consciously chosen ethic with an expanding circle of moral concern. Drawing on philosophy and evolutionary psychology, he demonstrates that human ethics cannot be explained by biology alone. Rather, it is our capacity for reasoning that makes moral progress possible. In a new afterword, Singer takes stock of his argument in light or recent research on the evolution of morality.--Publisher's description. (shrink)

What is attention? On one influential position, attention constitutively is the selection of some stimulus for coupling with a response. Wayne Wu has proposed a master argument for this position that relies on the claim that cognitive science commits to an empirical sufficient condition (ESC), according to which, if a subject S perceptually selects (or response-couples) X to guide performance of some experimental task T, she therein attends to X. In this paper I show that this claim about cognitive science (...) is false. Cognitive science allows for inattentive selection-for-task, or inattentive response-coupling. This means that Wu’s account is without independent support. (shrink)

Metaphysicians of a certain stripe are almost unanimously of the view that grounding is necessarily irreflexive, asymmetric, transitive, and well-founded. They deny the possibility of circles of ground and, therewith, the possibility of species of metaphysical coherentism. But what's so bad about circles of ground? One problem for coherentism might be that it ushers in anti-foundationalism: grounding loops give rise to infinite regresses. And this is bad because infinite grounding regresses are vicious. This article argues that circles of ground do (...) not necessarily give rise to infinite regresses, and where they do, those regresses are not necessarily vicious. (shrink)

The study of the fallacies has changed almost beyond recognition since Charles Hamblin called for a radical reappraisal of this area of logical inquiry in his 1970 book Fallacies. The “witless examples of his forbears” to which Hamblin referred have largely been replaced by more authentic cases of the fallacies in actual use. It is now not unusual for fallacy and argumentation theorists to draw on actual sources for examples of how the fallacies are used in our everyday reasoning. However, (...) an aspect of this move towards greater authenticity in the study of the fallacies, an aspect which has been almost universally neglected, is the attempt to subject the fallacies to empirical testing of the type which is more commonly associated with psychological experiments on reasoning. This paper addresses this omission in research on the fallacies by examining how subjects use two fallacies – circular argument and analogical argument – during a reasoning task in which subjects are required to consider a number of public health scenarios. Results are discussed in relation to a view of the fallacies as cognitive heuristics that facilitate reasoning in a context of uncertainty. (shrink)

Roland Barthes’ entire career pursued a dream of being freed from the tyranny of ossified, institutionalized, rote language use, as articulated from his first massively influential work on ‘writing degree zero’ in 1953. The anaemic role of institutional rhetoric and its dusty formulations dulled the capacity for using language and thought otherwise. For Barthes, fragments played a privileged role in the escape from the tyranny of meaning imposed by doxa and received wisdom, sometimes called ‘literature’ and ‘rhetoric’. Barthes once referred (...) to almost all of his writing, and indeed theorizing, as ‘a circle of fragments’. The artist and theorist Victor Burgin has been profoundly influenced by Barthes’ writings and his attempts to escape the ideological constraints of language, institutions and images. His visual rhetorical practice now often takes the form of projection loops that are accessible by gallery attendees at any point in the loop. Their basic building block is also the fragment, and the loop constitutes another circle of fragments. His 2016 work Belledonne uses the time Barthes spent in the sanatorium for tuberculosis treatment as the basis for the piece, its computer-generated imagery and textual intertitles. This article examines Barthes’s writings on pre-Socratic rhetoric, as well as his self-reflexive engagement with his own theorizing, combined with Burgin’s reconsideration of moving image work in gallery or museum spaces as attempts to offer potentially liberatory strategies for eluding rote use and effects of language, image and thought.

Descartes has been accused of reasoning in a circle since the publication of the Meditations. The Circle is easy to point out: it seems that Descartes employs clear and distinct perceptions to demonstrate God’s existence and benevolence, and the latter, in turn, validates the use of clear and distinct perceptions. But is Descartes really guilty of fallacious argument, or can we break the arc somehow?

This article is intended as a contribution to the current debates about the relationship between politics and the philosophy of science in the Vienna Circle. I reconsider this issue by shifting the focus from philosophy of science as theory to philosophy of science as practice. From this perspective I take as a starting point the Vienna Circle’s scientific world-conception and emphasize its practical nature: I reinterpret its tenets as a set of recommendations that express the particular epistemological attitude (...) in which both the Vienna Circle’s (doing) philosophy of science and its political engagement were rooted. -/- Regarding politics, and referring to new primary sources, I reconstruct how the scientific world-conception placed the Vienna Circle within a neoliberal-socialist political network that pursued concrete political aims. In light of my reconstruction I shall argue that neither the Vienna Circle’s alleged ethical noncognitivism nor its alleged adhesion to the Weberian ideal of a value-free science rules out the possibility of ascribing to the Vienna Circle a politically engaged philosophy of science: the case of the Vienna Circle shows how philosophy of science, as a public activity, can itself become a form of political engagement, even without necessarily entailing a theory of objective values.

In the Posterior Analytics, Aristotle takes up the position of those who hold that all knowledge is demonstrable, and, hence, scientific. Such people are said to base their arguments on the fact that some demonstrations are circular or reciprocal (72b251). As Aristotle makes clear in the text, a circular demonstration consists of an argument (form) in which the conclusion is equivalent to one of the premises. But as Aristotle hastens to point out, demonstrations cannot be circular, for the essence of (...) demonstration is to proceed from what is prior to what is posterior, and the same things cannot be both prior and posterior. A circular demonstration has the form ‘if A is, then B must be;’ and ‘if B is, then A must be’: “consequently, the upholders of circular demonstration are in the position of saying that if A is, A must be—a simple way of proving anything” (73a5).

The organisation of mammalian mitochondrial DNA (mtDNA) is more complex than usually assumed. Despite often being depicted as a simple circle, the topology of mtDNA can vary from supercoiled monomeric circles over catenanes and oligomers to complex multimeric networks. Replication of mtDNA is also not clear cut. Two different mechanisms of replication have been found in cultured cells and in most tissues: a strand‐asynchronous mode involving temporary RNA coverage of one strand, and a strand‐coupled mode rather resembling conventional nuclear (...) DNA replication. In addition, a recombination‐initiated replication mechanism is likely to be associated with the multimeric mtDNA networks found in human heart. Although an insight into the general principles and key factors of mtDNA organisation and maintenance has been gained over the last few years, there are many open questions regarding replication initiation, termination and physiological factors determining mtDNA organisation and replication mode. However, common themes in mtDNA maintenance across eukaryotic kingdoms can provide valuable lessons for future work. (shrink)

Members of Vienna Circle explicated determinism in terms of predictability in principle, or calculability. This paper attempts to uncover the rationale for this explication. It argues that the explication was an attempt to escape trivialization arguments; another important factor was the Circle’s views on meaning as testability.

As recent scholarship has repeatedly shown, the history of Vienna Circle is to some extent rooted in the tradition of Austrian Philosophy which Neurath considered as not involved in the “Kantian interlude”. Nevertheless, it seems that the heritage of Leibniz and, in particular, of his “reform of logic” has been hitherto neglected. Indeed, Leibnizianism (along with Herbartianism) represents a main feature of this tradition stretching from Bolzano to quite forgotten figures as Exner and Zimmermann, and still influent on the (...) Brentano circle. This paper attempt to highlight the role played by Leibniz in framing of the “scientific world conception”, focusing in particular both on Carnap’s and Neurath’s stance towards the characteristica universalis underlying the project of the encyclopedia Leibniz aimed to realize.

The apparently circular arguments in Descartes’s Meditations should be read as analytic arguments, as Descartes himself suggested. This both explains and excuses the appearance of circularity. Analysis “digs out” what is already present in the meditator’s mind but not yet “expressly known”. Once this is achieved, the meditator may take the result of analysis as an epistemic starting point independent of the original argument. That is, analytic arguments may be reversed to yield demonstrative proofs that follow an already worked-out order (...) of ideas. The “Cartesian Circle,” for example, is circular only when Descartes’s original analytic argument is mistaken for the demonstration that it enables. This approach to Cartesian Circles is unlike the standard approach, which attempts to show that Descartes’s original arguments do work as demonstrations after all. (shrink)

Foucault rejects the subject as a center, i.e. as a transparent self-conscious being, who gives meaning to his actions. However, ideas about subjects that think and will autonomously go on functioning within modern culture. Discourses on subjectivity call for an archeological and genealogical explanation. This compels Foucault to resort increasingly to subjectivity: as product and target of power, but also as a source of resistance and as an agent. After all, Foucault defines power as ‘actions about actions’. In the end, (...) Foucault started to circumscribe the teleology of his philosophical ethos as the production of new forms of subjectivity, in terms of freedom and autonomy. Concern is more with a continuous circling transgression, apprehending subjectivity as an aimless self-negation, than it is about a return of the subject. (shrink)

Friedrich Nietzsche was among the figures from the history of nineteenth century philosophy that, perhaps surprisingly, some of the Vienna Circle’s members had presented as one of their predecessors. While, primarily for political reasons, most Anglophone figures in the history of analytic philosophy had taken a dim view of Nietzsche, the Vienna Circle’s leader Moritz Schlick admired and praised Nietzsche, rejecting what he saw as a misinterpretation of Nietzsche as a militarist or proto-fascist. Schlick, Frank, Neurath, and Carnap (...) were in different ways committed to the view that Nietzsche made a significant contribution to the overcoming of metaphysics. Some of these philosophers praised the intimate connection Nietzsche drew between his philosophical outlook and empirical studies in psychology and physiology. In his 1912 lectures on Nietzsche, Schlick maintained that Nietzsche overcame an initial Schopenhauerian metaphysical-artistic phase in his thinking, and subsequently remained a positivist until his last writings. Frank and Neurath made the weaker claim that Nietzsche contributed to the development of a positivistic or scientific conception of the world. Schlick and Frank took a further step in seeing the mature Nietzsche as an Enlightenment thinker. (shrink)
