Résultat des recherches du philosophe allemand positiviste ayant pour objectif d'établir un système logique de constitution des concepts par dérivation, à partir d'un petit nombre de concepts fondamentaux.

Ideals (or ideal values) help people to navigate in social life. They indicate at a very fundamental level what people are concerned about, what they strive for, and what they want to be affiliated with. Transferring this to a leader-follower analysis, our first study (n = 306) confirms that followers' identification and satisfaction with their leaders are stronger, the more leaders match followers' ideal leader values. Study 2 (n = 244) extends the perspective by introducing the novel concept of counterideals (...) (i. e., how an ideal leader should not be) as a second, non-redundant point of reference. Results confirm that a leader's match on ideal and on counter-ideal values have independent effects in that both explain unique variance in followers' identification and satisfaction with their leader. Study 3 (n = 136) replicates the previous results in an experimental scenario study and provides evidence for the proposed causal direction of the underlying process. We conclude that counter-ideal values might be an additional point of reference that people use to triangulate targets above and beyond ideal values and discuss the implications of our findings for value research and management.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

Among the various meanings in which the word ‘probability’ is used in everyday language, in the discussion of scientists, and in the theories of probability, there are especially two which must be clearly distinguished. We shall use for them the terms ‘probability1’ and ‘probability2'. Probability1 is a logical concept, a certain logical relation between two sentences ; it is the same as the concept of degree of confirmation. I shall write briefly “c” for “degree of confirmation,” and “c” for “the (...) degree of confirmation of the hypothesis h on the evidence e“; the evidence is usually a report on the results of our observations. On the other hand, probability2 is an empirical concept; it is the relative frequency in the long run of one property with respect to another. The controversy between the so-called logical conception of probability, as represented e.g. by Keynes, and Jeffreys, and others, and the frequency conception, maintained e.g. by v. Mises and Reichenbach, seems to me futile. These two theories deal with two different probability concepts which are both of great importance for science. Therefore, the theories are not incompatible, but rather supplement each other. (shrink)

Uma leitura atenta de Para lá do Princípio de Prazer de Freud sugere que o mecanismo da repetição cega, a oposição a toda a mudança e uma vontade niilista em afirmar o seu próprio poder excessivo caracterizam todas as pulsões. O que distingue as pulsões de morte das outras pulsões deve ser procurado noutra coisa, tal como uma forma particular de prazer ou destruição agressiva. Apesar do seu regresso a Freud, Lacan dá conta de uma nova imagem do mecanismo de (...) repetição. Quer aquilo que se repete seja a expressão de um trauma quer seja de um desejo inconsciente, a repetição ameaça sempre o princípio de prazer e a sua gestão por um ego imaginário. Para Lacan, a repetição descontrolada apela insistentemente à instituição de um sujeito cujo desejo simbolicamente determinado se situa para lá do curso natural de um princípio de prazer. (shrink)

Moral behaviour, based on social norms, is commonly regarded as a hallmark of humans. Hitherto, humans are perceived to be the only species possessing social norms and to engage in moral behaviour. There is anecdotal evidence suggesting their presence in chimpanzees, but systematic studies are lacking. Here, we examine the evolution of human social norms and their underlying psychological mechanisms. For this, we distinguish between conventions, cultural social norms and universal social norms. We aim at exploring whether chimpanzees possess evolutionary (...) precursors of universal social norms seen in humans. Chimpanzees exhibit important preconditions for their presence and enforcement: tolerant societies, well-developed social-cognitive skills and empathetic competence. Here, we develop a theoretical framework for recognizing different functional levels of social norms and distinguish them from mere statistical behavioural regularities. Quasi social norms are found where animals behave functionally moral without having moral emotions. In proto social norms, moral emotions might be present but cannot be collectivized due to the absence of a uniquely human psychological trait, i.e. shared intentionality. Human social norms, whether they are universal or cultural, involve moral emotions and are collectivized. We will discuss behaviours in chimpanzees that represent potential evolutionary precursors of human universal social norms, with special focus on social interactions involving infants. We argue that chimpanzee infants occupy a special status within their communities and propose that tolerance towards them might represent a proto social norm. Finally, we discuss possible ways to test this theoretical framework. (shrink)

The article approaches the work of Van Breda and De Waelhens with respect to the question of how philosophical thought relates to the problems arising in natural life. Van Breda’s main contribution to philosophy is related to the exceptional natural skills he showed in his rescuing of E. Husserl’s Nachlass and his founding of the Husserl Archives in Leuven. It is lesser known that he also brought E. Husserrs widow to Leuven and rescued her from deportation by the German occupation (...) of Belgium during World War II. Extensive excerpts from Malvine Husserl’s private correspondence demonstrate her admiration for and gratitude towards Van Breda. This correspondence also gives us a good idea of her daily life during the seven years that she spent in Leuven, her strong character, and the reasons behind her conversion to Catholicism. Less anchored in natural life than Van Breda, De Waelhens nevertheless claimed that philosophy’s main task is to shed light on the problems of bodily human existence in its social dimensions and its relation to a linguistically-structured world. This led De Waelhens into a study first of Heidegger, then to Merleau-Ponty, Hegel and Marx and, finally, to psychoanalysis. But his entire work remained dedicated to a reflection on the relation between “philosophy and natural experiences‘. He understood this relation in strongly dialectical terms: philosophy must give natural life a better understanding of itself in order to allow it to play the role of a critical counter-balance to philosophical speculation. The article concludes with some of the author’s personal reflections on what philosophy can and cannot do in order to improve natural human life. (shrink)

. E. O. Wilson writes that the “choice between transcendentalism and empiricism” is this century's “version of the struggle for men's soul” . The transcendentalist argues for theism—that there is a God, a creator of the world. The empiricist instead makes the point that the notion of God, including morality and ethics, are adaptive structures of human evolution. Before entering the debate of the transcendentalist/empiricist controversy I analyze how things exist and suggest that all that is exists as united diversity, (...) as identity in difference. I argue that oneness by itself is intangible because wholes are concrete only through their tangible parts. I briefly discuss this understanding of existence in the realm of art to show that transcendence and immanence are not mutually exclusive but constitute each other. I conclude that existence, the hypostasis of unity in diversity, might be seen as a gift from absolute existence. In this view, the world might reveal itself as a gift that reflects the trinitarian existence of the Giver. (shrink)

The developments of recent years have made it more and more clear that one of the most fruitful approaches to the science of science, i.e. to a logical, epistemological and methodological analysis of science, consists in the analysis of the language of science. This analysis is meant not only as an analysis of the general structure of the scientific language, but also as an analysis of the expressions of that language as they are used in science, e.g. of the words (...) used, of the sentences of different forms asserted by scientists, of the theories consisting of such sentences, of proofs and derivations for such sentences, etc. (shrink)

German: Unter den nichtlogischen Konstanten der Wissenschaftssprache werden zwei Arten unterschieden, die Beobachtungsterme (z. B. « blau ») und die theoretischen Terme (z. B. « elektrisches Feld »). Die letzteren werden nicht durch Definitionen eingeführt, sondern durch Postulate zweier Arten, nämlich theoretische Postulate, zum Beispiel Grundgesetze der Physik, und Korrespondenzpostulate, die die theoretischen Terme mit Beobachtungstermen verbinden. Wie schon Hilbert gezeigt hat, können in dieser Weise sowohl die Mathematik als auch die theoretische Physik als ungedeutete Kalküle aufgestellt werden. Es wird (...) hier kurz erklärt, dass durch diesen Aufbau auch den mathematischen Termen eine Bedeutung (in einem weiteren Sinne) beigelegt wird. Die theoretischen Terme erhalten durch die Korrespondenzpostulate wenigstens eine unvollständige Deutung. Es wird gezeigt, wie die Unterscheidung von analytischen und synthetischen Sätzen auch für die theoretische Sprache definiert werden kann. -/- English: Among the non‐logical constants of the language of science two kinds are distinguished, the observation terms (e.g., « blue ») and the theoretical terms (e.g., « electric field »). The latter terms are introduced, not by definitions, but by postulates of two kinds, theoretical postulates, e.g., basic laws of physics, and correspondence postulates which connect the theoretical terms with observation terms. As Hilbert has explained, both mathematics and theoretical physics can in this way be constructed in the form of uninterpreted calculi. It is here briefly indicated that by this method of construction also the mathematical terms have meanings (in a wider sense) assigned to them. The theoretical terms obtain at least an incomplete interpretation by means of the correspondence postulates. It is shown how the distinction between analytic and synthetic sentences can be defined also for the theoretical language. (shrink)

Integration within constructive, especially intuitionistic mathematics in the sense of L. E. J. Brouwer, slightly differs from formal integration theories: Some classical results, especially Lebesgue's dominated convergence theorem, have tobe substituted by appropriate alternatives. Although there exist sophisticated, but rather laborious proposals, e.g. by E. Bishop and D. S. Bridges , the reference to partitions and the Riemann-integral, also with regard to the results obtained by R. Henstock and J. Kurzweil , seems to give a better direction. Especially, convergence theorems (...) can be proved by introducing the concept of “equi-integrability”. (shrink)

Language and imagination play a prominent role in Merleau-Ponty’s early reflections on literature. The “literary use of language” is opposed to usual or ordinary language, and it is also assigned the task of rejuvenating the latter. Merleau-Ponty is here openly inspired by Saussure and more secretly by Bergson. Poetic language is said to effect a coherent deformation of a linguistic code and to liberate signifiers from their subordination under a subjective meaning that directly refers to external objects. Literature also illustrates, (...) in exemplary fashion, the creative power of imagination and the effective force of fictions. This is where the discussion with Sartre comes into the picture. The article explores, in particular, what personal identity and the meaning of real facts owe not only to language but also to the imagination of possibilities. It further investigates the different notions of truth that apply to literary works of art. Literature is also shown to undermine the conception of the relation between fact and meaning, actuality and possibility, reality and fiction, truth and semblance in terms of dual oppositions. Most importantly, literary fictions and narratives can make a real change in the life of writers and readers by unfolding their unrealized personal potentialities, by refining their emotional sensibility, and by distancing them from themselves. In all this, an imaginative mode of ‘projection’ plays a central role. Le langage et l’imagination jouent un rôle de premier plan dans les réflexions de Merleau-Ponty sur la littérature. « L’usage littéraire du langage » est opposé au langage usuel ou ordinaire, et la tâche lui est également dévolue de rajeunir ce dernier. Merleau-Ponty s’inspire ouvertement de Saussure et plus secrètement de Bergson. Le langage poétique est dit effectuer une déformation cohérente du code linguistique et libérer les signifiants de leur subordination à une signification subjective qui réfère directement aux objets externes. La littérature illustre également, de manière exemplaire, la puissance créatrice de l’imagination et la force effective de la fiction. Ici la discussion avec Sartre entre en jeu. Mon article explore en particulier ce que l’identité personnelle et la signification des faits réels doit non seulement au langage, mais également à l’imagination des possibilités. Il discute également les différentes notions de vérité qui s’appliquent aux oeuvres d’art littéraires. Je montre aussi que la littérature empêche de concevoir comme des oppositions duelles les relations entre fait et signification, actualité et possibilité, réalité et fiction, vérité et vraisemblance. Par dessus tout, les fictions et narrations littéraires peuvent provoquer de réels changements dans la vie des écrivains et des lecteurs en déployant leurs potentialités personnelles non réalisées, en affinant leur sensibilité émotionnelle et en se distanciant d’eux-mêmes. Dans tout cela, le mode imaginatif de la projection joue un rôle central.Linguaggio e immaginazione rivestono un ruolo centrale nelle prime riflessioni di Merleau-Ponty sulla letteratura. L’“uso letterario del linguaggio” viene opposto al linguaggio ordinario o quotidiano e al primo viene inoltre assegnato l’incarico di rinnovare il secondo; in questo, Merleau-Ponty si ispira apertamente a Saussure e, in modo meno manifesto, a Bergson. Il linguaggio poetico è ritenuto in grado di imprimere una deformazione coerente a un determinato codice linguistico e di liberare i significanti dalla loro subordinazione a un significato soggettivo che si riferisce direttamente a oggetti esterni. La letteratura, inoltre, illustra in modo esemplare il potere creativo dell’immaginazione e la forza effettiva della finzione letteraria. È qui che entra in gioco la discussione con Sartre. Questo articolo esplora, in particolare, ciò che l’identità personale e il significato dei fatti reali debba non solamente al linguaggio, ma anche all’immaginazione delle possibilità; indaga inoltre le diverse nozioni di verità che possono essere applicate all’opera d’arte letteraria. L’articolo mostra poi come la letteratura possa mettere in discussione il carattere di opposizione binaria della relazione tra fatto e significato, attualità e possibilità, realtà e finzione, verità e verisimiglianza. In maniera significativa, le finzioni e le narrazioni letterarie possono cambiare la vita di scrittori e lettori svelando le loro potenzialità personali irrealizzate, raffinando la loro sensibilità emotiva e ponendoli a distanza da se stessi. In tutto questo, una modalità immaginativa di “proiezione” svolge un ruolo di primaria importanza. (shrink)

The Italian translation of R. Virchow’s conference of 1859 "Atome und Individuen". Virchow’s emphasis on the federal structure of the biological individual as composed of "cell-territories" supersedes the previous cellular atomis, and can be considered as a turning point in the establishment of a modular approach to the organism.
