John Corcoran’s natural deduction system for Aristotle’s syllogistic is reconsidered.Though Corcoran is no doubt right in interpreting Aristotle as viewing syllogisms as arguments and in rejecting Lukasiewicz’s treatment in terms of conditional sentences, it is argued that Corcoran is wrong in thinking that the only alternative is to construe Barbara and Celarent as deduction rules in a natural deduction system.An alternative is presented that is technically more elegant and equally compatible with the texts.The abstract role assigned by tradition (...) and Lukasiewicz to Barbara and Celarent is retained.The two ‘ perfect syllogisms’ serve as ‘basic elements’ in the construction of an inductively defined set of valid syllogisms.The proposal departs from Lukasiewicz, and follows Corcoran, however, in construing the construction as one in natural deduction.The result is a sequent system with fewer rules and in which Barbara and Celarent serve as basic deductions.To compare the theory to Corcoran’s, his original is reformulated in current terms and generalized.It is shown to be equivalent to the proposed sequent system, and several variations are discussed.For all systems mentioned, a method of Henkin‐style completeness proofs is given that is more direct and intuitive than Corcoran’s original.

This book traces the development of theories of the self and personal identity from the ancient Greeks to the present day. From Plato and Aristotle to Freud and Foucault, Raymond Martin and John Barresi explore the works of a wide range of thinkers and reveal the larger intellectual trends, controversies, and ideas that have revolutionized the way we think about ourselves. The authors open with ancient Greece, where the ideas of Plato, Aristotle, and the materialistic atomists laid (...) the groundwork for future theories. They then discuss the ideas of the church fathers and medieval and Renaissance philosophers, including St. Paul, Philo, Augustine, Aquinas, and Montaigne. In their coverage of the emergence of a new mechanistic conception of nature in the seventeenth century, Martin and Barresi note a shift away from religious and purely philosophical notions of self and personal identity to more scientific and social conceptions, a trend that has continued to the present day. They explore modern philosophy and psychology, including the origins of different traditions within each discipline, and explain both the theoretical relevance of feminism and gender and ethnic studies and also the ways that Derrida and other recent thinkers have challenged the very idea that a unified self or personal identity even exists. Martin and Barresi cover a number of issues broached by philosophers and psychologists, such as the existence of a fixed and unchanging self and whether the concept of the soul has a use outside of religious contexts. They address the question of whether notions of the soul and the self are still viable in today's world. Together, they reveal the fascinating ways in which great thinkers have grappled with these and other questions and the astounding impact their ideas have had on the development of self-understanding in the west.

Whether or not we adopt some form of physicalism in our thinking about the psychology of humans and other organisms we all believe that a mind is something that comes into being, changes, develops and decays. The correlation of the development and then later the decay of our mental powers with changes in the brain post-dates our belief that the mental realm is as much an area where things ebb and flow, come to be and pass away, as is the (...) physical. Even ancient authors who hold to the indestructibility of the soul allow that it changes in a host of ways. It is very odd, then, to discover that Aristotle appears to deny all this and feels impelled to treat the soul as unchanging and motionless. I propose to explore here exactly what Aristotle meant by saying the soul does not move and why he said it. In the end our investigation leads to some difficulties for Aristotle's psychological ontology which I am not able to resolve. (shrink)

Although there are a very few occasions on which Aristotle speaks of words, on the one hand, or mental concepts, on the other, as universals, he was no nominalist and no conceptualist. This negative thesis I have argued sufficiently, at least to my own satisfaction, in an earlier paper. He was, rather, a realist, but of a very tenuous sort. As I said in the earlier paper, he viewed universals as real entities but lacking numerical oneness; each is numerically (...) many, and yet each is also one in some sense. The specific identity of numerically distinct particulars creates something like a class, and this is the universal.This interpretation was not, in the earlier paper, defended against those who would attribute to Aristotle a much more robust form of realism, and it is that defense which this paper will undertake to provide. The evidence which can be marshalled for the more robust realism is impressive – more so, I would say, than that which can be brought forth for either the nominalist or the conceptualist interpretations. It rests on numerous passages which either explicitly or implicitly seem to tie together as identical, forms, substances, universals, and intelligible objects. (shrink)

As an early articulation of Heidegger's thought, this book is an indispensable resource for scholars and students."--BOOK JACKET.

First published in German in 1981 as volume 33 of Heidegger's Collected Works, this book translates a lecture course he presented at the University of Freiburg in 1931.

This chapter contains sections titled: The Philosophical Tale.

This book is an extensive review & analysis of Aristotelian thought as received & adapted by such medieval commentators as Ammonius, Philoponus, Boethius, al-Farabi, Yahya ibn 'Adi, Avicenna, Albertus Magnus, Thomas Aquinas, Martin of Dacia, Simon of Faversham, John Duns Scotus, Peter of Spain, Robert Kilwardby, William of Ockham, & Giles of Rome. The discussions range from metaphysics to logic, linguistics, & epistemology, encompassing such topics as being, god, causation, actuality, potentiality, universals, individuation, signification, cognition, certainty, infallibility, error, ignorance, (...) analogy, grammar, interpretation, foundationalism, & the eucharist & transubstantiation.

The paper describes the theory of the so-called “value-blindness” created by Dietrich von Hildebrand. The importance of the topic becomes apparent especially as its elaboration reveals a complex and dynamic relationship between moral cognitivity and fundamental moral attitudes of the cognizing subject. The article presents Hildebrand’s teaching on moral blindness as a coherent theory that was first introduced in the early work Sittlichkeit und ethische Werterkenntnis, and subsequently in the late Graven Images. By way of a conclusion the author examines (...) the relation between Hildebrand’s theory of moral blindness to Aristotle’s doctrine of acrasia. The significance of Hildebrand’s theory for fundamental systematic questions and problems of moral philosophy thus becomes manifest. (shrink)

The aim of the article is to compare and critically evaluate Kant’s, Aristotle’s, and von Hildebrand’s approach to the question of the moral accountability of emotions. Notoriously, Kant, in his practical philosophy, leaves hardly any place for the moral value of emotions. The only emotion that he acknowledges to possess a moral value is “Achtung für’s Gesetz”. According to Aristotle, emotions can be object of praise and blame in so far as they are formed by good or bad (...) habits. Von Hildebrand, not objecting to this approach of Aristotle, off ers a fi ne phenomenological analysis of how a “morally conscious” person modifi es emotions while experiencing them by either “sanctioning” or “disavowing” them. This analysis implies that emotions can be morally good or bad in still diff erent sense than the one considered by Aristotle. (shrink)

The concept of moral individualism is part of the foundational structure of most prominent modern moral philosophies. It rests on the assumption that moral obligations towards a respective individual are constituted solely by her or his capacities. Hence, these obligations are independent of any ἔθος, of any shared ethical sense and social significations. The moral agent and the individual with moral status are construed as subjects outside of any social relation or lifeworld significations. This assumption has been contested in the (...) last decades by diverse authors with very different approaches to moral philosophy. In the last years, an increasing number of philosophers like Cora Diamond and Alice Crary, but also phenomenologists like Paul Ricœur, Klaus Held, and Bernhard Waldenfels question the presupposition that individual capacities are the agent-neutral and context-neutral ground of moral considerations. This critique of moral individualism in different contemporary discourses shows a striking similarity between Wittgensteinian and phenomenological philosophers as their critical inquiry of prominent theories like the ones by Immanuel Kant, John Rawls, Peter Singer or Tom Regan is derived from mostly implicitly efficacious Aristotelian theorems. Telling examples are the ἔθος as pre-given normative infrastructure, the ἕξις as individual internalization of the ethos, the φρόνησις described as a specific practical know-how in contrast to scientific knowledge, and not at least the definition of the human being as ζῷον πολιτικόν. However, the Aristotelian sources of this movement have not yet been scrutinized systematically. This paper aims, first, to reveal the significance of these sources to make them visible and, second, to contribute to the notion of the topicality of Aristotelian philosophy in current debates on ethics.

This is a concise, comprehensive guide that covers the main schools of thought from the Ancient Chinese philosophies of Confucius and Lao Tzu; Ancient wisdom from Aristotle, Plato, Zeno and Pythagoras; through to those most influential of philosophers studied the world over -- Hegel, Marx, Descartes, Kant, Kierkegaard and Wittgenstein. It also discusses the "big questions," such as: What is truth? What kind of person is it good to be? What do we know and how do we know it? (...) It considers the relationship between philosophy and religion, and the problem of morality. The book takes a two-pronged approach that looks at the chronological development of philosophical thought and the people behind the different schools of thinking. These definitive guides to their subjects together have sold over three million copies worldwide. Their success is undoubtedly owed to the comprehensiveness and quality of content, for an excellent price, and the smaller size is nonetheless filled with 400 illustrations. (shrink)

An essential challenge of Aristotle’s Politics arises from the juxtaposition of contrasting and competing arguments in favour of virtuous monarchy, on the one hand, and the collective superiority of “the many”, on the other. This paper examines the purely theoretical reception of this contrast in the writings of some late medieval Aristotelians by focusing on a key section in Politics Γ (1280a8–1284b34). After reviewing Aristotle’s problematic position, the paper discusses its interpretation in the commentaries of Albert the Great, (...) Thomas Aquinas/Peter of Auvergne and Walter Burley, as well as its use in the works of Giles of Rome, John of Paris and Marsilius of Padua. On that basis, finally, the paper outlines some general trends with regard to how medieval scholars dealt with Aristotle’s idea of the rule of the many as opposed to that of one or few virtuous persons.

Resumen: El tema del presente artículo es la recepción y radicalización heideggeriana de la aporía del tiempo y el alma en Aristóteles en los textos del periodo conocido como la década fenomenológica. La cuestión acerca de si habría o no tiempo en caso de que no existiera el alma conduce a una difícil aporía que queda sin respuesta en el corpus aristotelicum. Heidegger piensa que el planteamiento aporético muestra que Aristóteles intuye ya que el Dasein mismo debe considerarse fundamentalmente tiempo. (...) Puesto que el tiempo es la determinación básica de la existencia humana, el Dasein sería imposible sin el tiempo. En otras palabras, no habría Dasein sin tiempo.: The subject of the present paper is Heidegger’s reception and radicalization of Aristotle’s aporia of time and soul in the texts of the period known as the phenomenological decade. The question about whether there would be time without the existence of soul leads to a difficult aporia which remains unanswered in the corpus aristotelicum. Nevertheless, Heidegger believes that this aporetical approach shows that Aristotle already sensed that Dasein itself is to be considered fundamentally as time. Since time is the basic determination of human existence, Dasein would be impossible without time. In other words, there would not be a Dasein without time. (shrink)

Care of the soul is arguably the core concept in Patočka’s phenomenology. However, what is the soul? In this paper I seek to determine its ontological meaning, connecting the concept of caring for the soul with that of the movement of existence. Starting from Patočka’s affirmative presentation of Aristotle’s criticism of Plato, I interrogate the “orthodox” Platonic concept of caring for the soul and develop an alternative notion, putting emphasis on action in the world. I demonstrate the impossibility of (...) identifying the third movement with true existence, or with the care for the soul, whether conceived as the performance of philosophy or as political action. Finally, I outline a reinterpreted concept of care for the soul in which the self-moving of the soul is not ontologically prior to responding. The soul is inherent in action; and it is free only as responding to the world and responsible only in being free. (shrink)

Das in seinen Einzelheiten so überaus verästelte und verwickelte Problem der Aristotelesübersetzungen und der Aristotelesrezeption im 12. und 13. Jahrhundert schreitet auf drei vielfach in einander übergehenden Forschungswegen der endgültigen Lösung entgegen. Die erste Forschungsmethode faßt die handschriftliche Überlieferung ins Auge und sucht aus der Zusammensetzung und der Eigenart der lateinischen Aristoteleskodizes die Schichten und Formen zu erkennen, in welchen das aristotelische Schrifttum in arabisch-lateinischer und griechisch-lateinischer Übersetzung dem mittelalterlichen Denken überliefert wurde. Von besonderem Werte sind hier Notizen in den (...) Handschriften, welche über die Entstehungszeit einer Übersetzung und über die Persönlichkeit des Übersetzers Auskunft geben. [Aus der Einleitung].

Durch rastlose Forschungsarbeit der letzten Jahrzehnte ist der gewaltige Einfluß, den das Eindringen der aristotelischen Philosophie in Verbindung mit der arabischen Philosophie und Naturwissenschaft auf die Entwicklung des späteren mittelalterlichen Geisteslebens ausgeübt hat, immer mehr und mehr ins Licht gestellt worden. Mühsame Einzelforschung - denn nur sie, nicht geistvolle Linienziehung gibt auf diesem schwierigen Gebiete sichere Führung - hat die Entwicklungsphasen der mittelalterlichen Aristotelesrezeption aufgehellt. Wenn nunmehr die Union académique internationale auf Vorschlag der polnischen Akademie der Wissenschaften das große Werk (...) eines Aristoteles latinus, einer kritischen Edition der mittelalterlichen lateinischen Aristotelesübersetzungen, in Angriff genommen hat und unter der Leitung von G. Lacombe hierfür die Vorbereitungs- und Inventarisierarbeit im weitesten Umfang geleistet worden ist, so geht für die mittelalterliche geisteswissenschaftliche Forschung ein Wunsch in Erfüllung, den Clemens Baeumker und auch ich in unseren Arbeiten so lebhaft zum Ausdruck gebracht haben. Ich hatte, als ich im Jahre 1916, durch die Kriegsverhältnisse eingeengt, mein Buch »Forschungen über die lateinischen Aristotelesübersetzungen des 13. Jahrhunderts« schrieb, nicht daran gedacht, daß in so verhältnismäßig kurzer Zeit der Plan einer Ausgabe der mittelalterlichen lateinischen Aristotelesübertragungen, der auch eine Gesamtausgabe der Werke des Averroes in sich begreifen soll, gefaßt und in so energischer, zielbewußter Weise der Verwirklichung entgegengeführt würde.

The Phenomenology of Religious Life presents the text of Heidegger’s important 1920–21 lectures on religion. The volume consists of the famous lecture course Introduction to the Phenomenology of Religion, a course on Augustine and Neoplatonism, and notes for a course on The Philosophical Foundations of Medieval Mysticism that was never delivered. Heidegger’s engagements with Aristotle, St. Paul, Augustine, and Luther give readers a sense of what phenomenology would come to mean in the mature expression of his thought. Heidegger reveals (...) an impressive display of theological knowledge, protecting Christian life experience from Greek philosophy and defending Paul against Nietzsche. (shrink)

Publisher's description: The Phenomenology of Religious Life presents the text of Heidegger's important 1920621 lectures on religion. First published in 1995 as volume 60 of the Gesamtausgabe, the work reveals a young Heidegger searching for the striking language that eventually formed the mature expression of his thought. The volume consists of the famous lecture course "Introduction to the Phenomenology of Religion," a course on "Augustine and Neoplatonism," and notes for a course on "The Philosophical Foundations of Medieval Mysticism" that was (...) never delivered. Heidegger's engagements with Aristotle, St. Paul, Augustine, and Luther give readers a sense of what phenomenology would come to mean in his later works. Here, Heidegger reveals an impressive display of theological knowledge, protecting Christian life experience from Greek philosophy and defending Paul against Nietzsche. The appearance of this first English translation marks a significant event in Heidegger scholarship and affords a unique look into his phenomenology. (shrink)

First published in 1988 as volume 63 of his Collected Works, Ontology—The Hermeneutics of Facticity is the text of Heidegger's lecture course at the University of Freiburg during the summer of 1923. In these lectures, Heidegger reviews and makes critical appropriations of the hermeneutic tradition from Plato, Aristotle, and Augustine to Schleiermacher and Dilthey in order to reformulate the question of being on the basis of facticity and the everyday world. Specific themes deal with the history of ontology, the (...) development of phenomenology and its relation to Hegelian dialectic, traditional theological and philosophical concepts of man, the present situation of philosophy, and the influences of Aristotle, Luther, Kierkegaard, and Husserl on Heidegger's thinking. Students of Heidegger will find initial breakthroughs in his unique elaboration of the meaning of human experience and the "question of being," which received mature expression in Being and Time.

Biology is the most extensive field in the Corpus Aristotelicum. In his fundamental work De anima, Aristotle tries to fix the borders of this life science. The term ψυχή has a twofold explanatory status. On the one hand, ψυχή is understood as a principle of all living beings. On the other hand, it is understood as a cause of the fact that all living beings are alive. The paper is divided into three sections. The first part shows why (...) class='Hi'>Aristotle discusses these issues in a work entitled Περὶ ψυχῆς. Since Pythagoras and Heraclitus, ψυχή was understood as a life principle: Pythagoras believed that men, animals and plants share the same nature: they are all ἔμψυχα and they are homogenous qua ψυχή. The second part of this article deals with Aristotle’s definition of the soul in DA II: ψυχή is the principle of all living things. This establishes the external criteria to divide living and non-living beings and the internal criteria to divide living beings. The third part of this paper is concerned with the methodological consequences of this definition: the life functions are the central explanandum in Aristotle’s biology. De anima II defines such various life-functions as nourishment, sense-perception and locomotion. These capacities contour the main fields of the philosopher’s biological investigation. For Aristotle, the faculty of reproduction is a subtype of nourishment. Reproduction is the most important and most natural function of all living beings. Genetics is, therefore, the most important field in Aristotle’s biology. (shrink)

This volume reconstructs Martin Heidegger's lecture course at the University of Marburg in the winter semester of 1924-25, which was devoted to an interpretation of Plato and Aristotle.

Volume 18 of Martin Heidegger's collected works presents his important 1924 Marburg lectures which anticipate much of the revolutionary thinking that he subsequently articulated in Being and Time. Here are the seeds of the ideas that would become Heidegger's unique phenomenology. Heidegger interprets Aristotle's Rhetoric and looks closely at the Greek notion of pathos. These lectures offer special insight into the development of his concepts of care and concern, being-at-hand, being-in-the-world, and attunement, which were later elaborated in Being (...) and Time. Available in English for the first time, they make a significant contribution to ancient philosophy, Aristotle studies, Continental philosophy, and phenomenology. (shrink)

This article seeks to contribute to the discussion on the nature of choice in virtue theory. If several different actions are available to the virtuous agent, they are also likely to vary in their degree of virtue, at least in some situations. Yet, it is widely agreed that once an action is recognised as virtuous there is no higher level of virtue. In this paper we discuss how the virtue theorist could accommodate both these seemingly conflicting ideas. We discuss this (...) issue from a modern Aristotelian perspective, as opposed to a purely exegetic one. We propose a way of resolving what seems to be a major clash between two central features of virtue ethics. Our proposal is based on the notion of parity, a concept which recently has received considerable attention in the literature on axiology. Briefly put, two alternatives are on a par (or are ‘roughly equal’) if they are comparable, although it is not the case that one is better than the other, nor that they are equally good. The advantages of applying the concept of parity to our problem are twofold. Firstly, it sheds new light on the account of choice in virtue theory. Secondly, some of the criticisms that have been mounted against the possibility of parity can be countered by considering the notion of choice from a virtue theory perspective. (shrink)

The purpose of this study was to explore if and how social media might come to bear on people’s understanding of ethics. Participants were asked to complete online surveys regarding social media interaction and respond to 14 scenarios depicting ethical dilemmas. Our results suggest that social media and people’s perceptions of ethics do share a relationship. Specifically, we found that people who reported being exposed to ethical violations on social media were more likely to find our unethical scenarios to be (...) personally unacceptable, to be of lower ethicality, and to react negatively to the content. These findings suggest that mere exposure to ethical violations is enough to produce awareness in people regarding ethical issues, which carries significant implications for ethics education.

Lo studio esamina il tema della legge umana e dell'equità , che risulta di notevole importanza per la comprensione della filosofia pratica aristotelica, in Roberto Grossatesta, Alberto Magno e Tommaso d'Aquino a partire da Ethica Nicomachea V. 10. Dopo una breve premessa in cui si espongono le linee guida del saggio, l'A. si sofferma sul capitolo aristotelico, per poi esporre lo status questionis nei canonisti medievali e nei testi pastorali prima della ricezione dell'Etica; l'ultima parte è dedicata al significativo apporto (...) che questa ha dato alla discussione medievale. Se Grossatesta fa ampio ricorso a tale nozione nella discussione del rapporto tra diritto naturale e diritto positivo, Alberto riafferma l'importanza di tale concetto e l'opportunità di utilizzarlo quando la legge, per il suo carattere di universalità, risulti inadeguata e sia necessario ripristinare la giustizia. La trattazione più sistematica è comunque offerta da Tommaso d'Aquino, in particolare nel commento all'Ethica Nicomachea e nella Summa theologiae, che impiega la nozione di aequitas in un senso più vicino a quello aristotelico che a quello dei canonisti o alla tradizione del diritto romano. La filosofia aristotelica è così all'origine di un rinvigorimento della discussione sull'aequitas canonica che offrirà nuovi sviluppi nel campo della filosofia morale e del diritto in epoca tardomedievale.

"I am a Jew who was born and who grew up in a Catholic country; I never had a religious education; my Jewish identity is in large measure the result of persecution." This brief autobiographical statement is a key to understanding Carlo Ginzburg's interest in the topic of his latest book: distance. In nine linked essays, he addresses the question: "What is the exact distance that permits us to see things as they are?" To understand our world, suggests Ginzburg, it (...) is necessary to find a balance between being so close to the object that our vision is warped by familiarity or so far from it that the distance becomes distorting. Opening with a reflection on the sense of feeling astray, of familiarization and defamiliarization, the author goes on to consider the concepts of perspective, representation, imagery, and myth. Arising from the theme of proximity is the recurring issue of the opposition between Jews and Christians -- a topic Ginzburg explores with an impressive array of examples, from Latin translations of Greek and Hebrew scriptures to Pope John Paul II's recent apology to the Jews for antisemitism. Moving with equal acuity from Aristotle to Marcus Aurelius to Montaigne to Voltaire, touching on philosophy, history, philology, and ethics, and including examples from present-day popular culture, the book offers a new perspective on the universally relevant theme of distance.

The idea of a self-organized system brings both political and biological discourses together, for they both aim at explaining how a certain compound can achieve self-unity out of plurality. Whereas biological metaphors in politics have been much examined, political metaphors in biology have not. In this paper I intend to show how political metaphors can enlighten biological discourses, taking the work of Aristotle as a case-study. The relationship between the main elements of a living-body could be better understood within (...) a political scheme: the soul rules over the body through pneuma, its prime minister. This scheme entails, thus, to re-examine Aristotle’s definition of soul in the light of the key concept of pneuma, and to replace the hylemorphic explanation with a triadic one. On the one hand, soul is the entelecheia of the body as it keeps both the form and the end of the organism, which is its unity. On the other hand, the moving-efficacious principle that performs unity by circulating through the body, and by linking the body to its environment is pneuma. Therefore, the political formula: “the king does not govern” could shed light upon the structure of the living body: whereas the soul rules the body, pneuma governs it. Although Aristotle does not build his biology upon political concepts, metaphors are already there, shaping his explanations, within the bio-theo-political paradigm of autarchy. (shrink)
