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.

The traditional picture of the development of analytical philosophy, represented especially by such thinkers as G. Frege, G. E. Moore, B. Russell or R. Carnap, whose attitude was generally anti-metaphysical, can, on closer study, be shown to be incomplete. This article treats of the Cracow circle – a group of Polish philosophers among whom are, above all, to be counted J. Salamucha, J. M. Bocheński, J. F. Drewnowski, and B. Sobociński, who were, at the beginning of the twentieth (...) century, fascinated by the development of modern formal logic and its application to philosophical thinking. They also attempted to apply it to Catholic philosophy. The result of their endeavours were many remarkable works introducing not only a defence of the use of modern philosophical approaches in Christian thought, but also the reconstruction, by means of formal logic, of significant proofs given by Scholastic authors.

Józef M. Bocheński began his philosophical career as an eclectic philosopher, then switched to Thomism and finally became a representative of the analytic school. As a Thomist he wanted to reform this orientation by the resources of modern formal logic. This tendency culminated in the establishment of the Cracow Circle (established in 1936) whose members were Bocheński, Jan F. Drewnowski, Jan Salamucha, and Bolesław Sobociński. However, the program of the Cracow Circle was rejected by most Thomists (...) who considered traditional logic as an entirely sufficient device of philosophy. Bocheński was very disappointed by this attitude of his Thomist fellows. His evolution toward analytic philosophy, free of any ideological pressure, can be regarded as his reaction to the conservatism of Thomism. (shrink)

The aim of this paper is to present and analyse the views on logic of the members of the so-called Cracow Circle, namely the Dominican Father Józef M. Bocheński, Rev. Jan Salamucha, and Jan Franciszek Drewnowski. They tried to apply the methods of modern formal/mathematical logic to philosophical and theological problems. In particular, they attempted to modernise contemporary Thomism by employing logical tools. The influence of Jan Łukasiewicz, the co-founder of the Warsaw School of Logic will be also (...) discussed. --------------- Received: 16/01/2021. Reviewed: 24/03/2021. Accepted: 13/05/2021.

Jan Salamucha was born on the 10th of June 1903 in Warsaw and murdered on the 11th of August 1944 in Warsaw during the Warsaw Uprising very early on in his scholarly career. He is the most original representative of the branch of the Lvov-Warsaw School known as the Cracow Circle. The Circle was a grouping of scholars who were interested in reconstructing scholasticism and Christian philosophy in general by means of mathematical logic. As Jan Lukasiewicz’s successor (...) in the area of logic and Konstanty Michalski’s student in the area of the history of medieval thought, Salamucha had an excellent preparation for this task. His main achievements include a masterful logical analysis of the proof _ex motu _for the existence of God, a modern interpretation of analogical notions and a comprehensive approach to the problem of essence. He also contributed several historical studies: he examined Aristotle’s theory of deduction, he reconstructed William Ockham’s propositional logic and established the authenticity of his treatise on _insolubilia,_ and he identified the historical sources of the antinomies in Antiquity and the Middle Ages. He did not shy away from popularizing philosophy, and in that work he was able to elucidate rather than oversimplify the complexities of philosophy. (shrink)

Philosophers of religion of the Cracow Circle (1934-1944) are the principal precursors of what is now called the analytic philosophy of religion. The widespread claim that the analytic philosophy of religion was from the beginning an Anglo-American affair is an ill-informed one. It is demonstrable that the enterprise, although not the label "analytic philosophy of religion," appeared in Poland in the 1930’s. Józef Bochenski’s postwar work is a development of the Cracow Circle’s prewar work in the (...) analytic philosophy of religion, or at least of important elements of that earlier work. Bochenski’s approach in his ’Logic of Religion’ is quite original and might still be profitably studied and discussed by philosophers of religion of the analytic persuasion. (shrink)

The paper offers a historical survey of the emergence of logical formalization in twentieth-century analytically oriented philosophy of religion. This development is taken to have passed through three main ?stages?: a pioneering stage in the late nineteenth and early twentieth centuries (led by Frege and Russell), a stage of crisis in the 1920s and early 1930s (occasioned by Wittgenstein, logical positivists such as Carnap, and neo-Thomists such as Maritain), and a stage of rehabilitation in the 1930s, 1940s, and 1950s (led (...) by the Cracow Circle and Quine).

This article is an overview of the philosophy of informatics with a special regard to some Polish philosophers. It juxtaposes the informationistic worldview with the long-prevailing mechanical conceptualization of nature before introducing the metaphysical perspective of the information revolution in sciences. The article shows also how ontic pancomputationalism – regarded as an update to structural realism – could enrich the philosophical research in some classical topics. The paper concludes with a discussion of the philosophy of Jan Salamucha, a philosopher from (...) the Cracow Circle whose ideas could be inspiring for today’s philosophy of informatics in Cracow.

In this article I present a special contribution to universalism by the Cracow Circle (Bocheński, Drewnowski, Salamucha). Presented thinkers were scientists, philosophers and theologians, and tried to combine these disciplines in their works. They took standards of rationality from logic and other sciences, and applied them to Christian philosophy and theology. This kind of rationality can be considered universal and when we use this rationality in dialogue between religion and other worldviews, the dialogue has a chance to be (...) really universal.

J.M. Bocheński together with J. Salamucha, B. Sobociński, and J.F. Drewnowski formed the so-called Cracow Circle in the 30s of the previous century. Its main aim was to utilize contemporary logic in theology and philosophy of God. The first work in this area was Salamucha’s formal analysis of the prima via, published in 1934. The article was reviewed by Bocheński, who provided a number of remarks concerning Salamucha’s analysis. At that time he did not decide to conduct a (...) holistic research into the prima via. That was done by him only at the end of his life as part of the logical analysis of the quinque viae. This paper aims at presenting Bocheński’s unpublished formal analysis of the prima via from 1953 and proving that it constitutes a valuable completion of his published formal analyses, which come from the 1980s and 1990s. Above all, they provide a more insightful analysis of the notion of movement in the prima via, as well as the form of axiom expressing the lack of regress into infinity. In the formalizations of 1953 there are also interesting analyses concerning the ancestral closure of three-argument relations. (shrink)

The purpose of this paper is to analyse and compare two concepts which tend to be treated as synonymous, and to show the difference between them: these are critical thinking and logical culture. Firstly, we try to show that these cannot be considered identical or strictly equivalent: i.e. that the concept of logical culture includes more than just critical thinking skills. Secondly, we try to show that Christian philosophers, when arguing about philosophical matters and teaching philosophy to students, should not (...) focus only on critical thinking skills, but rather also consider logical culture. This, as we argue, may help to improve debate both within and outside of Christian philosophy. (shrink)

On the 11th of January, 2001 the Philosophical Circle of the University School of Philosophy and of Education Ignatianum in Cracow organised a philosophical symposium on: The subject of metaphysics and the way of its determination. This problem seems important nowadays, although it has been discussed throughout the whole philosophical tradition. Solutions concerning basic philosophical problems have their impact on the understanding of reality, first of all the human being and the culture created by him which is expressed (...) in knowledge, morality, arts and religion. Reflection on the foundations of philosophy is especially important in the contemporary intellectual climate which is dominated by relativism and nihilism. This is demonstrated by Pope John Paul II in his encyclical Fides et Ratio, which also proposes the way of overcoming the crisis through the return to the philosophy of being, that is metaphysics. The guests invited to the symposium belong to the above-mentioned philosophical trend. (shrink)

An illustrated study of the early twentieth-century transformation from Expressionism to Constructivism and beyond in the Central European arts. Central European Avant-Gardes presents the first interpretive overview of the complex webs of interaction among the artists and intellectuals of early twentieth-century Central Europe. The key stylistic transformation of the period was from Expressionism to Constructivism, as artists and writers, against a volatile background of war and revolution, saw the opportunity literally to construct a new world through their work. The borders (...) between the visual arts, photography, film, architecture, poetry, and typography were obliterated, as artists sought to transcend the forces of traditionalism to forge an elemental visual language that would overcome national and linguistic boundaries. Yet at the same time that these artists advocated pluralism and unity, their work engaged issues such as nationalism and tradition that still resonate in artistic circles today. The book, which accompanies a major exhibition organized by the Los Angeles County Museum of Art and curated by Timothy Benson, assisted by Monika Krol, is arranged around events and situations rather than by linear, art historical categories. It features hundreds of color plates and reproductions of documents; discussions of movements from Artificialism to Zenitism; essays on figures, publications, and exhibitions; and shorter "city views" of Belgrade, Berlin, Bucharest, Budapest, Cracow, Dessau, Ljubljana, £ódz, Poznañ, Prague, Vienna, Warsaw, Weimar, and Zagreb.

In the former socialist countries the relation of philosophy to social reality, as shaped by the political interests of the State, must be considered for each particular case with a view to the historical dynamics of its own development. The Polish case is not typical in this regard — it was determined by the failure of forced sovietization at the institutional, cultural level and the maintenance of Poland''s traditional contacts with Western European culture. In this regard Polish universities played an (...) important role since they preserved normal structures of academic activity.Philosophy in Poland has been marked by three currents which managed to rebuff the advances of Marxism. Best known among them is the Lwów-Warsaw school of logic and analytic philosophy. Its contribution is especially important in the methodology of philosophical inquiry and the style of responsible philosophical discourse. Though not a bed of political opposition the school''s members mounted a spiritual opposition to Marxism, especially during the Solidarity period. Catholic philosophy, as represented by the Catholic University of Lublin (KUL), has been and remains a completely independent force in Eastern and Central Europe. Doctrinally, Catholic philosophy in Poland has been divided between a more traditional, dated Thomism and the more progressive circles in Cracow where Western European philosophy, especially phenomenology, existentialism, and hermeneutics, has been influential (the significance of Józef Tischner and Karol Wojtyla, now Pope Jean Paul II). The third major current, centered in Cracow, is the phenomenology of Roman Ingarden, whose influence is manifest in a style of philosophizing that has attracted professional philosophers as well as committed intellectuals from different disciplines.

Against this diversified background Marxism had to prove its mettle, a requirement that explains the unique internal differentiation and pluralism within Polish Marxist philosophy. The decisive factors in its development were its rejection of Soviet Marxism-Leninism and the opening to Western Marxism. The often remarked 'revisionist' character of Polish Marxism consists in the recognition by its most talented representatives of the fundamental incompatibility between Marxism as the ideological legitimation of the Communist state and as a philosophy subject to rational criteria. In effect, Polish Marxists thought the theory through to its end, and in this sense brought to light its inherently unstable nature: to be a philosophy it would have to cease to be Marxist, to be Marxist means having to pander to ideology. The confrontation of the diverse currents in Polish philosophy contributed to an unfortunate result: for political reasons non-Marxists steered clear of social philosophical questions, while official Marxism, which suppressed the 'revisionist' trend, obfuscated the relation between philosophy and social reality. Today philosophy in Poland has the urgent task to contribute to the reconstruction of a social rationality combining a critical consciousness with moral elements of commitment and responsibility.

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)

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.

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.

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?
