Research that is initiated, designed or funded by sponsor agencies based in countries with relatively high social and economic development, and conducted in countries that are relatively less developed, gives rise to many important ethical challenges. Although clinical trials of HIV vaccines began ten years ago in the US and Europe, an increasing number of trials are now being conducted or planned in other countries, including several that are considered “developing” countries. Safeguarding the rights and welfare of individuals participating as (...) research subjects in developing countries is a priority. In September, 1997, the Joint United Nations Programme on HIV/AIDS embarked on a process of international consultation; its purpose was further to define the important ethical issues and to formulate guidance that might facilitate the ethical design and conduct of HIV vaccine trials in international contexts. This paper summarises the major outcomes of the UNAIDS consultative process. (shrink)

Most epistemologists hold that knowledge entails belief. However, proponents of this claim rarely offer a positive argument in support of it. Rather, they tend to treat the view as obvious and assert that there are no convincing counterexamples. We find this strategy to be problematic. We do not find the standard view obvious, and moreover, we think there are cases in which it is intuitively plausible that a subject knows some proposition P without—or at least without determinately—believing that P. Accordingly, (...) we present five plausible examples of knowledge without (determinate) belief, and we present empirical evidence suggesting that our intuitions about these scenarios are not atypical.

The paper is a critical discussion of scholarship on the "Critique of Pure Reason" published during the past ten years. The emphasis is on Anglo-American authors. I identify and discuss three main trends in the field: a shift from the general discussion of transcendental arguments to the analysis and evaluation of particular proofs in Kant; a renewed interest in the doctrine of transcendental idealism and the distinction between things in themselves and appearances; and the emergence of an entire body of (...) literature on Kant's philosophy of mind, centered around the idea of a "transcendental psychology." The main body of the text is supplemented by extensive bibliographical information provided in the notes. (shrink)

As Husserl already noticed, artworks themselves have a phenomenological character. This means, however, that to experience artworks as phenomena no “epoché” and no “phenomenological reduction” is necessary. The leading question of my essay is whether, and possibly how, this observation can be methodologically generalized for understanding phenomena. I discuss if, and possibly how, a phenomenological reflection on art allows and even demands a general conception of phenomenology that nevertheless does not confuse artworks with phenomena in general. My intention is to (...) show that and how phenomenality can be clarified with reference to its spatial character. Accordingly, works of architecture that are artworks will play a decisive role in my argument. (shrink)

Scientific exploration and thus our knowledge about the outside world is subject to the conditions of our experience.These conditions are condensed here into an interface model which,besides being physical,has an additional interface structure not reducible to physics. We suggest that this structure can dynamically be characterized by separate modes.Their selection and operation presupposes free will and a rudimentary concept of time and space. Based on some analogies with quantum networks it is argued that the 'observed' gets 'dressed'as a consequence of (...) the observing. Interface dynamics and system dynamics supplement each other without over- determination. (shrink)

During much of the past century, it was widely believed that phonemes--the human speech sounds that constitute words--have no inherent semantic meaning, and that the relationship between a combination of phonemes (a word) and its referent is simply arbitrary. Although recent work has challenged this picture by revealing psychological associations between certain phonemes and particular semantic contents, the precise mechanisms underlying these associations have not been fully elucidated. Here we provide novel evidence that certain phonemes have an inherent, non-arbitrary emotional (...) quality. Moreover, we show that the perceived emotional valence of certain phoneme combinations depends on a specific acoustic feature--namely, the dynamic shift within the phonemes' first two frequency components. These data suggest a phoneme-relevant acoustic property influencing the communication of emotion in humans, and provide further evidence against previously held assumptions regarding the structure of human language. This finding has potential applications for a variety of social, educational, clinical, and marketing contexts. (shrink)

Landgrebe and Smith provide an argument for the impossibility of Artificial General Intelligence based on the limits of simulating complex systems. However, their argument presupposes a very contemporary vision of artificial intelligence as a model trained on data to produce an algorithm executable in a modern digital computing system. The present contribution explores what it means to be artificial. Current artificial intelligence approaches on modern computing systems are not the only conceivable way in which artificial intelligence technology might be created. (...) If there are conceivable routes by which an artificial intelligence might be developed that are not constrained in the same way as the current generation of artificial neural networks, then these might be plausible routes towards the engineered generation of artificial general intelligence that are not precluded by the Landgrebe and Smith argument against the possibility of artificial general intelligence.

Statements about the behavior of biochemical entities (e.g., about the interaction between two proteins) abound in the literature on molecular biology and are increasingly becoming the targets of information extraction and text mining techniques. We show that an accurate analysis of the semantics of such statements reveals a number of ambiguities that have to be taken into account in the practice of biomedical ontology engineering: Such statements can not only be understood as event reporting statements, but also as ascriptions of (...) dispositions or tendencies that may or may not refer to collectives of interacting molecules or even to collectives of interaction events.

The pressures that led to the evolution of episodic memory have recently seen much discussion, but a fully satisfactory account of them is still lacking. We seek to make progress in this debate by taking a step backward, identifying four possible ways that episodic memory could evolve in relation to simulationist future planning—a similar and seemingly related ability. After distinguishing each of these possibilities, the paper critically discusses existing accounts of the evolution of episodic memory. It then presents a novel (...) argument in favor of the view that episodic memory is a by-product of the evolution of simulationist future planning. The paper ends by showing that this position allows for the maintenance of the traditional view that episodic memory operates on stored memory traces, as well as explaining a number of key features of episodic memory: its being subject to frequent and systematic errors, its neural co-location with the capacity for simulationist future planning, and the potential existence of non-human episodic memory.

This paper deals with the recent policies introduced in Brazil in order to foster a public interest towards science. Persuasive messages and strategies aiming at increasing a public awareness of the importance of scientific literacy for the development of the country are introduced at different levels and targeting different kinds of publics. These policies are analysed in view of classical models of social influence and persuasion.

O presente artigo estabelece algumas das linhas fundamentais relativas à recepção do pensamento de Søren Kierkegaard desde a segunda metade do século XIX até ao presente. Para além de algumas observações sobre o panorama europeu no seu conjunto e o desenvolvimento do mesmo processo na América do Norte, o artigo focaliza a sua atenção no caso alemão, sendo que o autor enfatiza sobretudo a recepção filosófica e teológica do pensador de Copenhaga, pelo que, naturalmente, os âmbitos da literatura e da (...) Teoria Literária são tocados apenas de forma marginal. Assim, o artigo oferece-nos uma história da recepção da obra kierkegaardiana em quatro fases distintas, as quais se mostra corresponderem a seis modos fundamentais de recepção: entre 1860-1890 (recepção sem produção ou produção sem recepção); entre 1890--1910 (sobretudo recepção não-produtiva); entre 1910-1945 (sobretudo recepção produtiva ou formas mistas); desde 1945 (sobretudo produção receptiva). /// The article outlines major historical trends and types of the reception of Kierkegaard's thought between mid 19th century and the present. Occasional glances at the European and American situation notwithstanding it is focused on a survey of the German development. Moreover, the emphasis lies on the philosophical and theological reception, whereas the literary and literature-theoretical aspects of the subject are only touched upon marginally. The upshot of the analysis is a reception-history, which unfolds, roughly speaking, in four basic stages, corresponding in a particular way to six major types of reception: around 1860-1890 (mainly either reception without production or production without reception); around 1890-1910 (mainly unproductive reception); around 1910-1945 (mainly either productive reception or mixed types); since 1945 (mainly receptive production).

Humans are standouts in their propensity to trade. More specially, the kind of trading found in humans—featuring the exchange of many different goods and services with many different others, for the mutual benefit of all the involved parties—far exceeds anything that is found in any other creature. However, a number of important questions about this propensity remain open. First, it is not clear exactly what makes this propensity so different in the human case from that of other animals. Second, it (...) is not clear why other animals did not acquire this propensity to the extent that humans did. Third, it is not clear what explains the fact that the extent to which humans engage in trade is culturally highly variable. The paper argues that at the heart of the human-animal divergence in this propensity is the particular socio-cultural environment in which humans evolved. This has led them to sometimes, but not always, acquire the cognitive technology (writing, algebra, tallying devices, money, etc.) to support a sophisticated disposition and capacity for reciprocal cooperation, and deep and wide concepts of property and exchange value.

Fichte's System of Ethics, published in 1798, is at once the most accessible presentation of its author's comprehensive philosophical project, The Science of Knowledge or Wissenschaftslehre, and the most important work in moral philosophy written between Kant and Hegel. Fichte's ethics integrates the discussion of our moral duties into the systematic framework of a transcendental theory of the human subject. Its major philosophical themes include the practical nature of self-consciousness, the relation between reason and volition, the essential role of the (...) drives in human willing, the possibility of changing the natural world, the reality of one's own body, the reality of other human beings, and the practical necessity of social relations between human beings. This volume offers a translation of the work together with an introduction that sets it in its philosophical and historical contexts. (shrink)

Statements about the behavior of biological entities, e.g. about the interaction between two proteins, abound in the literature on molecular biology and are increasingly becoming the targets of information extraction and text mining techniques. We show that an accurate analysis of the semantics of such statements reveals a number of ambiguities that is necessary to take into account in the practice of biomedical ontology engineering. Several concurring formalizations are proposed. Emphasis is laid on the discussion of biological dispositions.

We propose that children employ specialized cognitive systems that allow them to recover an accurate “causal map” of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed graphical causal models, or “Bayes nets”. Children’s causal learning and inference may involve computations similar to those for learning causal Bayes nets and for predicting with them. Experimental results suggest that 2- to 4-year-old children (...) construct new causal maps and that their learning is consistent with the Bayes net formalism. (shrink)

This article compares Kant and Fichte from the double stand- point of identity and difference with regard to two thinkers who were at first united by a master-student relation but who later on drifted apart from each other due to mutual defamation. At the center of the present discussion stands the relationship between spirit of freedom and system’s form which binds Kant and Fichte beyond methodological divergences and doctrinal differ- ences. The critical comparison between Kant and Fichte will be developed (...) in four steps: it will start with the general positioning of Kant within German Idealism, and then move on to Kant’s double critical enterprise of grounding an aprioristic doctrine of principles of nature and freedom; it will later on address the conception championed by Fichte of having pre- sented the “first system of freedom”, and from there it will focus on the manifestations of freedom within Fichte’s philosophical system, with Kant’s position as contrast.

El presente artículo compara a Kant y a Fichte en la perspectiva doble de identidad y diferencia referida a dos pensadores a quienes une una primera relación de maestro y alumno y a quienes separa una posterior difamación mutua. En el centro de la presentación se encuentra la relación entre espíritu de libertad y forma del sistema que une a Kant y a Fichte más allá de divergencias metódicas y de diferencias doctrinales. La comparación crítica entre Kant y Fichte se (...) desarrollará en cuatro etapas: partirá de la ubicación general de Kant dentro del idealismo alemán y se extenderá a la empresa doble de Kant, expresada de forma crítica, de una doctrina de los principios apriorística de naturaleza y libertad, para después ir a la concepción enfáticamente reclamada por Fichte de un “primer sistema de la libertad”,[1] y de ahí a las manifestaciones de la libertad en el sistema filosófico de Fichte, teniendo como punto de vista rector el contraste con Kant.[2] Palabras clave: [1] En la forma de citación de la Gesamtausgabe de Fichte se señalará el tomo y el volumen con números romanos y arábigos respectivamente, y después el número de página en cuestión. [2] El presente artículo es parte de un proyecto de carácter más amplio, cuyo tema es la dilucidación del aporte filosófico de Kant y de Fichte; de ahí que se haga continua referencia a publicaciones particulares de mi autoría.

Understanding causal structure is a central task of human cognition. Causal learning underpins the development of our concepts and categories, our intuitive theories, and our capacities for planning, imagination and inference. During the last few years, there has been an interdisciplinary revolution in our understanding of learning and reasoning: Researchers in philosophy, psychology, and computation have discovered new mechanisms for learning the causal structure of the world. This new work provides a rigorous, formal basis for theory theories of concepts and (...) cognitive development, and moreover, the causal learning mechanisms it has uncovered go dramatically beyond the traditional mechanisms of both nativist theories, such as modularity theories, and empiricist ones, such as association or connectionism.
