De acordo com a concepção dominante de causação, eventos espácio-temporalmente localizáveis que podem ser designados por termos singulares e descrições definidas são os únicos relata genuínos da relação causal. Isto dá apoio e é apoiado pela dicotomia aceita entre a explicação causal, concebida como uma relação intensional entre fatos ou verdades, e a relação natural e extensional da causação. O ensaio questiona este modo de ver e argumenta pela legitimidade da noção de causação por fatos: os relata de muitas relações (...) expressas pelo conector sentencial ‘(O fato) C causa (o fato) E’ podem ser causas e efeitos genuínos (I). Esta visão expandida da causação é então aplicada ao problema da causação mental. Assumindo a verdade do realizacionismo físico, o ensaio explora a conexão entre eficácia causal e relevância contrafactual de propriedades. Mostra-se que, pelo menos em muitos casos, as ligações contrafactuais corretas, requeridas pela causação, podem ser encontradas somente no nível dos fatos realizados, não no nível mais básico dos fatos realizadores (II). Finalmente, dadas as similaridades entre a defesa do fisicismo não-reducionista esboçada aqui e as tentativas menos modestas de justificação científica das pretensões do materialismo metafísico, justamente criticadas por van Fraassen como manifestações da ‘falsa consciência’, considera-se se e como a argumento principal do ensaio pode evitar o juízo crítico de van Fraassen (III).

This book challenges the common view that classical education in 19th-century Germany was dominated by a progressive ideal called neohumanism. The prevailing ideal of education at the German Gymnasien was emphatically traditional and is best described as classical humanism. Moreover, this 19th-century classical humanism dynamically related to modern society and should therefore be seen as the continuation of a living tradition.".

O presente trabalho tem por objetivo apresentar os principais aspectos do Empirismo Construtivo de Bas C. van Fraassen, particularmente no que diz respeito ao problema do sucesso científico. Nesse contexto, serão examinadas as noções de observável e inobservável e suas relações com o ‘argumento do milagre’ e da ‘coincidência cósmica’, ambos criticados por van Fraassen. As respostas de autores que defendem o Realismo Científico serão então apresentadas, contrapondo-se aos argumentos do Empirismo Construtivo. Finalmente, possíveis dificuldades do Empirismo Construtivo serão ainda (...) examinadas e uma proposta para superá-las será apresentada. (shrink)

Projet En développant son « empirisme constructif », Bas Van Fraassen est devenu une référence incontournable pour la philosophie des sciences contemporaine. Après la vague de critiques qui, vers les années 1960, avait fait perdre à l'empirisme logique sa prédominance dans le champ des idées, le réalisme scientifique semblait s'être imposé comme le seul compte rendu acceptable du travail et des orientations de la recherche. Quine avait beau énoncer ce que pourrait être un empirisme affranchi de ses deux « dogmes (...) » (l'intangibilité de la distinction vérités analytiques / vérités synthétiques, et la réduction des constructions aux « faits »), le programme d'une philosophie des sciences empiriste renouvelée restait à l'état d'esquisse. Mais par trois ouvrages successifs, Scientific Image (1980), Laws and symmetry (1989), et Quantum mechanics an empiricist view (1991), Van Fraassen a posé les bases d'un empirisme viable, parce que capable de prendre en charge la plupart des spécificités dont se prévaut le réalisme contre l'empirisme classique ou logique, et de rendre raison des développements les plus actuels de la physique. Contre l'empirisme classique ou logique, les réalistes font d'abord valoir que la réduction de toute réalité et de tout acte de référence aux phénomènes, ne rend justice ni à la pratique du langage courant ni à celle des sciences. Lorsque quelqu'un procède à une dénomination, il ne cherche pas à désigner par là une tranche d'apparaître, ou quelque ensemble fini et répertorié d'apparitions; il pointe vers "quelque chose" dont les modalités de manifestation sans fin assignable sont pour partie anticipées et pour partie ouvertes. De même, quand un chercheur scientifique parle de l'objet de ses investigations, il ne limite pas son discours à un ensemble fini de résultats d'expérience obtenus sous des conditions instrumentales actuellement disponibles; il renvoie à une entité dont la variété des manifestations futures est prévue aussi complètement que possible (et avec un succès croissant) par des cadres conceptuels et théoriques révisables. Face à cette objection, Van Fraassen fait jouer un rôle capital aux modèles dans sa version de l'empirisme.. (shrink)

The relation between Emanuel Swedenborg and Immanuel Kant has been the subject of many discussions. The chief aim of this paper is not to elucidate this question from an historical point of view, but to compare the teachings of the two thinkers, as those teachings have come to us. Kant's "Träme eines Geistersehers" embodies a very unfavourable opinion about Swedenborg. It is a curious circumstance, that this judgement is not based on decisive arguments. On the contrary, Swedenborg's fundamental doctrines about (...) the existence of a spiritual world and the communication between the living and the dead, are accepted by Kant as plausible. Du Prel and others have concluded, that Kant was a Swedenborgian in his heart, and that his negative attitude was due to the fear of losing his scientific reputation. A careful consideration of the two philosophical systems does not tend to bear out this opinion; nevertheless, such a comparative study is very instructive. In the mental development of the two thinkers there are remarkable analogies. Both were occupied with the great problems of God and the human soul; and both were disappointed by the leading philosophical and theological doctrines of their days. To Swedenborg those doctrines seemed to lead straightforwardly to naturalism and atheism. Kant was struck by the diversity of the opinions expressed and by the succession of heterogeneous doctrines without lasting results. But the reactions of the two men in these circumstances were different. In his cosmological and anatomical works Swedenborg aims at acquiring a comprehensive view of the Universe, in which view God and the soul should obtain their proper places. When he had reached the age of about 55 years, a crisis set in, which he described as "the opening of his spiritual senses". From that time he could see the spiritual world and speak with its inhabitants; he could study the workings of God and of the soul with the help of living experience. Kant raised the question, whether there are departments of knowledge in which certainty is attainable, and what is the ground of this certainty. His answer is, that the fundamental propositions of mathematical physics are absolutely certain. The ground lies in the fact, that these propositions are not derived from experience, but that they are "synthetic judgments a priori". They express the workings of the "categories" and "forms of intuition". by means of which the mind constructs, out of a chaos of sense-impressions, the ordered universe of science. Of objects to which these propositions do not apply, e.g. God and the soul, no certain knowledge is possible. This precludes the knowledge of "another world", fundamentally different from our ordinary world. So there seems to be an irreconcilable opposition between the teachings of Kant and of Swedenborg, But further considerations tend to lessen this contrast. Notwithstanding his own teaching, Kant accepted a life after death and he even speculated on it. If we follow this example, we come to remarkable conclusions. It is reasonable to suppose, that the spirits, who have been men, use the same categories as we do. Then out of the impressions which reach them, they will construct a world built on the same pattern as our earthly world. So life before and after death will not be very different. And this is precisely Swedenborg's teaching. This may be confirmed by the experiences of our dream-life. In dreams, our mind out of different impressions builds a world closely resembling our ordinary world. The spiritual world, as described by Swedenborg, presents many analogies with the world of our dreams. Now it is a very remarkable circumstance, that modern physics has been under the necessity of modifying the system of categories as described by Kant. In quantum mechanics the connection between cause and effect is less stringent than in classical mechanics. This adds fresh interest to the study of a system like that of Swedenborg, where quantitative laws are largely replaced by qualitative laws. (shrink)

What is empiricism and what could it be? Bas C. van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines, but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing, recurrent critique of metaphysics, (...) and second in a focus on experience that requires a voluntarist view of belief and opinion._ _Van Fraassen focuses on the philosophical problems of scientific and conceptual revolutions and on the not unrelated ruptures between religious and secular ways of seeing or conceiving of ourselves. He explores what it is to be or not be secular and points the way toward a new relationship between secularism and science within philosophy. (shrink)

Bas C. van Fraassen                          Princeton University       My topics today are the relation between science and myth, and the possibility of empiricism as an approach to life as well as to science. But philosophy is a thoroughly historical enterprise, a dialogue that continues in the present but is always almost entirely (...) shaped by our past. So I will devote the first half of this talk to setting the historical stage.

Metaphysicians speak of laws of nature in terms of necessity and universality; scientists, in terms of symmetry and invariance. In this book van Fraassen argues that no metaphysical account of laws can succeed. He analyzes and rejects the arguments that there are laws of nature, or that we must believe there are, and argues that we should disregard the idea of law as an adequate clue to science. After exploring what this means for general epistemology, the author develops the empiricist (...) view of science as a construction of models to represent the phenomena. (shrink)

In this book van Fraassen develops an alternative to scientific realism by constructing and evaluating three mutually reinforcing theories.

This article asks whether states have a right to close their borders because of their right to self-determination, as proposed recently by Christopher Wellman, Michael Walzer, and others. It asks the fundamental question whether self-determination can, in even its most unrestricted form, support the exclusion of immigrants. I argue that the answer is no. To show this, I construct three different ways in which one might use the idea of self-determination to justify immigration restrictions and show that each of these (...) arguments fails. My conclusion is that the nature and value of self-determination have to do with the conditions of genuine self-government, not membership of political society. Consequently, the demand for open borders is fully consistent with respect to self-determination. (shrink)

The attempt to formulate a viable empiricist and non-foundationalist epistemology of science faces four problems here confronted. The first is an apparent loss of objectivity in science, in the conditions of use of models in applied science. The second derives from the theory-infection of scientific language, with an apparent loss of objective conditions of truth and reference. The third, often cited as objection to The Scientific Image, is the apparent theory-dependence of the distinction between what is and is not observable. (...) The fourth and last is the loss of the possibility of objective evaluation of rationality in scientific methodology. It is argued that each of these problems is illusory. (shrink)

The author argues that quantum theory admits a plurality of interpretations, each aiding further understanding of the theory, but also advocating specifically the Copenhagen Variant of the Modal Interpretation. That variant is applied to topics like the Einstein-Podolsky-Rosen paradox and the problem of 'identical' particles.

This is surely a bit of Socrates' famous irony. He draws the analogy to explain how his friends should regard poetry as they regretfully banish it from the ideal state. But lovers were no more sensible then than they are now. The advice to banish poetry, undermined already by Plato's own delight and skill in drama, is perhaps undermined still further by this evocation of a 'sensible' lover who counts love so well lost. Yet Socrates' image is one of avowed (...) rationality and prudence. The sensible lover imitates the older literary example of Ulysses' tying himself to the mast. (The example belongs therefore to the class of problems treated in Elster (1979)). Both this lover and Ulysses foresee that under certain possible future conditions, their opinions, values and preferences will or would differ from what they are now, in a very definite fashion. To what extent is such foresight possible? Correspondingly (when we do not claim foreknowledge) to what extent is such opinion reasonable, rational, coherent, or consistent in some suitably broad sense? It is not easy to understand exactly what is possible or even logically permissible in this respect. In an earlier paper, "Belief and the Will", I argued for a principle ("Reflection") to govern such deliberation. Here I will both generalize the treatment of opinion in "Belief and the Will" and respond to criticism. Critical examples mainly resembled the story of Ulysses who foresaw a period of dysfunction (at the sound 2 of the sirens) in his epistemic and/or doxastic future. Other criticism focused on the model of opinion used (precise numerical subjective probability) and on the merits of Dutch Book arguments. The present argument will not rely on Dutch Book arguments and strategies, and the Reflection principle will be formulated so as to apply also to vague opinion. (shrink)
