In this essay I investigate the interplay between actual and potential properties of a thing within an Aristotelian conceptual framework. A minimal formal treatment of such interplay is proposed, outlining the actual or possible causal impact of these properties with respect to the changes of a thing in question. I also mention the historically interesting controversy between Aristotle and the Megarians concerning the relationship between power and act, as well as Hintikka’s application of the Principle of Plenitude. The essay ends (...) with certain suggestions for treating the problems of actual and potential properties by means of dispositions and contrary-to-fact conditionals. (shrink)

There are two fundamental questions concerning the choice and presence of objects in various formal systems: Where do these objects come from? What do we know about them? To answer these questions I introduce the notion of a proto-ontology as the pre-theoretic realm of entities from which the basic objects – individuals – of the formal system S are postulated. The pragmatic aspects of such choices are investigated with regard to first-order logic, both pure and applied, set theory and mereology. (...) It is claimed that the postulated objects enter the formal system S with a package of properties and relationships, the recognition of which depends on the interpretation and application of the available predicates of S. If these properties and relationships are not made explicit, a possible clash may arise between them and the properties and relationships “assigned” to the individuals of S by the interpreted predicates of S. As regards the relationship between logic and metaphysics, I contend that logic can perhaps be viewed as the articulation of the fundamental features of proto-ontological objects without which no discourse or theory would be possible. In this sense logic could also be viewed as a theory and method of the construction of a well-articulated metaphysical theory. (shrink)

When A. J. Ayer commented on Russell’s theory of acquaintance, he claimed that the person who is acquainted with an object knows that the object exists and also that the object in question has the properties which it appears to have. This essay employs Russell’s theory of knowledge by acquaintance from the period between 1910 and 1918 and critically analyzes both the existential and the descriptive statements as they are related to the object of acquaintance. In particular, Ayer’s views on (...) the relationship between appearance and reality are treated as unacceptable from any sound epistemological point of view. I believe that the logical analysis of these epistemological problems reveals intricate issues involved in such discussions, which transcend their limited historical context. (shrink)

In this essay, I investigate the dynamic foundations of Hume’s philosophy which is so heavily dependent upon Newton’s physics. Hume’s ubiquitous phrase „force and vivacity” is symptomatic of his dynamic, rather than voluntaristic, position that dominates his interpretation of impressions, ideas, and causality in particular. After pointing out some inconsistencies of Hume’s Newtonism, I concentrate on Hume’s treatment of power. It is a well-known fact that Hume rejected natural powers, in fear of their occult character, but accepted human powers giving (...) them an actualist interpretation. I suggest that there is a dispositional treatment hidden in Hume’s statements which puts Hume in line with other philosophers of power. (shrink)

Roku 1906 Łukasiewicz uverejnil podnetný návrh na logický výklad kauzálneho vzťahu pomocou pojmu nevyhnutnosti a jednoduchej závislosti. Uplatnil v ňom zákon transpozície, známy z výrokovej logiky, a modálne úvahy . Vo svojej historicky motivovanej analýze Łukasiewiczovho návrhu autor ukazuje, že Łukasiewiczovi sa nepodarilo oddeliť vzťah príčiny a účinku od vzťahu dôvodu a dôsledku, ani špecifikovať príslušné modality. Napriek tomu Łukasiewicz si zaslúži uznanie za pioniersky pokus traktovať tradičný filozofický problém kauzality netradičnými prostriedkami logiky relácií.

This historically oriented article describes Whiteheadś life-long concern with logic. Although his creative phase in logic seemed to have ended with the publication of Principia Mathematica, he remained continuously interested in logic of relations and theory of events and even as a speculative metaphysician appreciated logic as - in his words - his "first love".

Many philosophers have attempted to offer a logical theory of objects, employing different techniques. Thus R. Carnap tried to “reconstruct” logically the world by using the modern symbolic logic, while N. Goodman “constructed” the world with the help of the calculus of individuals or the logic of part-whole relations. W.V. Quine helped to steer the attention toward the question of ontological commitment and toward a theory of objects produced by a logical analysis of natural languages. Recently, there have been controversial (...) discussions concerning the metaphysical and logical aspects of objects in actual and possible worlds as well as new contributions to the theory of nonexistent objects, rekindling the old Russell-Meinong controversy. It seems that even the proposed theories of events, such as that of R. M. Martin, maintain the great significance of the notion of an object. Then there is a plethora of the so-called intensional objects, such as the alleged objects of propositional attitudes, the story of which is tied with the names of Frege, Russell, Carnap and many others. Is it possible to give an all-embracing theory of objects which would satisfy all the parties involved? Although such possibility may be very questionable, the instrumental role of logic for the development of the metaphysical theories of objects is indisputable. Two factors are, however, involved in the constitution of a logical theory of objects: the basis or the given data from which the theory starts; the logical apparatus employed, i.e., the logical axioms and rules of inference, just as the relevant semantical rules which are formulated in the metalanguage. While the logical apparatus is usually very clear, at least in the case of the formally well-construed theories, the given basis of a metaphysical theory T—as we may call it—might contain many tacit assumptions which would need a lot of clarification. It seems that philosophers fight more about the presuppositions and assertions of their systems than about the logic involved. I would like to discuss the interplay between the above two factors, starting with the realm of the given objects. As to the second factor—the logical apparatus involved—the contributions of first-order predicate logic and of the calculus of individuals will be considered. (shrink)

A propositional interpretation of knowledge by acquaintance seems more promising than the nonpropositional one, endorsed by Russell. According to the propositional interpretation, to be acquainted with an object means to attend (pay attention) to individuating features of the object. For the actual, direct acquaintance with an object, a subject's perception of the object and his attending to the individuating features of it (just as the fact that these features do belonge to the object in question) are the essential factors. Proper (...) names of objects and subject's memory images referring to objects of acquaintance may be viewed as their special individuating features (in spite of being attached to these objects "externally"). For the dispositional (non-actual) notion of acquaintance, a relativization of time must be added, together with the subject's ability to attend to the individuating features of the object under proper conditions (when the object of previous acquaintance is presented or represented to the subject). Although the conditional formulas expressing these situations contribute to the explication of the concept of knowledge by acquaintance, their truth-status remains open and contingent upon the ways of solving the problem of individuation (identification).

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K.

The violation of Bell inequalities seems to establish an important fact about the world: that it is non-local. However, this result relies on the assumption of the statistical independence of the measurement settings with respect to potential past events that might have determined them. Superdeterminism refers to the view that a local, and determinist, account of Bell inequalities violations is possible, by rejecting this assumption of statistical independence. We examine and clarify various problems with superdeterminism, looking in particular at its (...) consequences on the nature of scientific laws and scientific reasoning. We argue that the view requires a neo-Humean account of at least some laws, and creates a significant problem for the use of statistical independence in other parts of physics and science more generally.

Versuche zur Bestimmung der Abhängigkeit der Unterschiedsschwelle einer geometrischen Grössendimension von der Intensität bei verschiedener schwacher, nahe der absoluten Intensitätsschwelle liegender Lichter. Im Gegensatz zu den komplizierten Formeln, die die Abhängigkeit bei höheren Lichtintensitäten dargeben, gilt nahe der Minimalschwelle der Intensität ein bilinearer Ausdruck der Invarianz des Produkts der Reizunterschiedsschwelle der Grössendimension und der Lichtintensität . Die Bedeutung des Befundes im Zusammenhang mit früheren ähnlichen Ergebnissen wird besprochen.Experiments on determination of the difference threshold of visual size using different, weak lights, (...) near the absolute intensity threshold, are presented. Contrary to the complicated formulae obtained when the light is bright, near the minimal intensity threshold a simple bilinear equation holds true: the product of the stimulus threshold of visual size and the intensity threshold is found to be invariant. The significance of the findings are discussed in connection with similar, previous results.Des expériences pour déterminer le seuil spatial différentiel , en utilisant différentes lumières faibles, à la limite du seuil de l'intensité absolue, sont exposées.

La signification de ce fait est discutée, en même temps que des résultats analogues antérieurs. (shrink)

"Translated with an uncanny sense for the overall point of Augustine's doctrine. In short, a very good translation. The Introduction is admirably clear." --Paul Vincent Spade, Indiana University.

Russell’s distinction between knowledge by acquaintance and knowledge by description has been recently re-examined in frequently controversial epistemo-logical contributions. The present essay reflects upon the pertinent papers by D. F. Pears, J. Hintikka, R. Chisholm, W. Sellars, A. J. Ayer, and others, but is pri-marily founded on Russell’s significant formulations from his writings published between 1910 and 1918. By employing an auxiliary device of a late-Wittgen-steinian language game, I explore at first the situation in which human subject is “experiencing” and (...) naming particular objects and later the subject’s acquaintance with universals. The reconstruction of such situations shows that, contrary to Russell’s assumptions, even the “purest” acquaintance cannot function without knowledge by description, i.e. without sta-ting propositions about the object of acquaintance . Then the only “descriptionless” alternative would be a kind of intuitive knowledge of such objects which is difficult to reconcile with the position held by Russell in the 1910s. Whatever the consequences, this topic retains its fundamental epistemological significance. (shrink)

This is a sequel to Augustine Shutte's previous book Philosophy for Africa. In that book he engages with some concepts central to traditional African thinking about human nature and society. In this book he offers a new interpretation of the chief ethical idea in African thought, Ubuntu. He argues that it complements the central European ethical notion of individual freedom, and shows how the two ideas can be combined to form an ethic based on a richer understanding of our humanity. (...) He then applies this ethic to different spheres of life: gender relations, sex and family life, education, health care, work, politics and religion. In each sphere he tries to show how an ethic of Ubuntu can provide concrete guidance for our continuing struggle to make a multi-cultural South Africa a truly humane society. (shrink)

Usually called (...) the “Cassiciacum dialogues,” these four works are of a high literary and intellectual quality, combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting his whimsical levity and ironic wryness. _On Order_ is the third work in this tetralogy, and it is Augustine’s only work explicitly devoted to theodicy, the reconciliation of Almighty God’s goodness with evil’s existence. In this dialogue, Augustine argues that a certain kind of self-knowledge is the key to unlocking the answers to theodicy’s vexing questions, and he devotes the latter half of the dialogue to an excursus on the liberal arts as disciplines that will help strengthen the mind to know itself and God.

_A fresh, new translation of Augustine’s fourth work as a Christian convert_ The first four works written by St. Augustine of Hippo after his conversion to Christianity are dialogues that have influenced prominent thinkers from Boethius to Bernard Lonergan. Usually called the Cassiciacum dialogues, these four works are of a high literary and intellectual quality, combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting his whimsical levity (...) and ironic wryness. _Soliloquies_ is the fourth work in this tetralogy. Augustine coined the term “soliloquy” to describe this new form of dialogue. _Soliloquies__,_ a conversation between Augustine and his reason, fuses the dialogue genre and Roman theater, opening with a search for intellectual and moral self-knowledge before converging on the nature of truth and the question of the soul’s immortality. Foley’s volume also includes _On the Immortality of the Soul__,_ which consists of notes for the unfinished portion of the work. (shrink)

In this new translation the brilliant and impassioned descriptions of Augustine's colourful early life are conveyed to the English reader with accuracy and art. Augustine tells of his wrestlings to master his sexual drive, his rare ascent from a humble Algerian farm to the edge of the corridors of high power at the imperial court of Milan, and his renunciation of secular ambition and marriage as he recovered the faith that his mother had taught him. It was in a Milan (...) garden that Augustine finally achieved the act of will to Christian conversion, which he compared to a lazy man in bed finally deciding it is time to get up and face the day. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe.

In this article religion is defined in terms of our concern for the fulfilment of our most fundamental natural desires, especially those that seem beyond all human power to fulfil, such as the achievement of death-transcending life or a complete and enduring community between free beings such as human persons are. A god is always seen as the source of power sufficient to achieve this in us. Our conceptions of our god and of human nature are therefore always linked. The (...) arguments for the existence of a god in the history of European philosophy show this. From the cosmological arguments of pre-modern times, through arguments from design and anthropological arguments in the modern period, to a contemporary argument from interpersonal relationships, a deepening insight into human nature produces an evermore comprehensive conception of a god, one that is not incompatible with a scientific worldview, or the secular rejection of the supernatural in the name of human freedom.

There is little doubt that a second-order axiomatization of Zermelo-Fraenkel set theory plus the axiom of choice (ZFC) is desirable. One advantage of such an axiomatization is that it permits us to express the principles underlying the first-order schemata of separation and replacement. Another is its almost-categoricity: M is a model of second-order ZFC if and only if it is isomorphic to a model of the form Vκ, ∈ ∩ (Vκ × Vκ) , for κ a strongly inaccessible ordinal.

The De Doctrina Christiana is one of Augustine's most important works on the classical tradition. Undertaken at the same time as the Confessions, is sheds light on the development of Augustine's thought, especially in the areas of ethics, hermeneutics, and sign-theory. What is most interesting, however, is its careful attempt to indicate precisely what elements of a classical education are valuable for a Christian, and how the precepts of Ciceronian rhetoric may be used to communicate Christian truth. An up-to-date translation (...) has long been necessary, for readers of Augustine and all who study the early church, or the classical tradition, or the history of literary criticism or Biblical interpretation. This completely new translation gives a close but stylish representation of Augustine's thought and expression. A succinct introduction and select bibliography embodies the results of recent work.

The present study aims to investigate the psychological mechanisms beneath the change in the facial expression of some of the beheaded characters in Caravaggio’s works, starting from The Head of Medusa, from the artist’s youth, and reaching David with the Head of Goliath, a mature workpiece, searching the continuity between them through a series of self-portraits/ self-insertions of the artist in his work. The psychodynamic analysis is limited by the constitution of its practice to the study of the process of (...) image production and the artistic imaginary, rather than to the investigation of man or the artist out of reach by means of figurative and symbolic language. This approach aims to highlight the drives of the unconscious, the structures of censorship and the technique of operating of the defensive mechanisms that ultimately could contribute to the production of such masterful images that are both seductive and confusing. The study incorporates and continues the contribution of authors such as Leo Bersani and Ulysse Dutoit who applied Laplanche’s theory of generalized seduction theory in the analysis of Caravaggio’s works, but also the mirror stage of Lacan and the masterful study of Winnicott regarding the reflection of the baby in the mimics of his mother, an unconscious unclear image that will stand forever for the perception of the self. The change of the affective resonance, expressiveness and emotional relating to violence is natural in the course of human evolution. While not even the artist Caravaggio can elude it, his work can illustrate by deflection these transforma­tions of the dynamics of the mind, it can raise new questions and open new perspectives of understanding the artistic drive.

ABSTRACTThis article aims to bring some understanding to the phenomenon called compassion. The use of particular linguistic expressions to denote the phenomenon of compassion in the East and West can confuse us, as those terms are embedded in unique cultural settings. This article undertakes a historical, etymological, and philosophical exploration of the terms, compassion and karuna. The article will include a short literature review of these concepts and an investigation of the differences and similarities between them. The concluding speculation is (...) that the Western perspective on compassion is founded on an individualistic, self-centred vision, and the karuna of the East is founded on a communitarian, non-self based vision.
