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)

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)

Spatial attention and eye-movements are tightly coupled, but the precise nature of this coupling is controversial. The influential but controversial Premotor theory of attention makes four specific predictions about the relationship between motor preparation and spatial attention. Firstly, spatial attention and motor preparation use the same neural substrates. Secondly, spatial attention is functionally equivalent to planning goal directed actions such as eye-movements (i.e. planning an action is both necessary and sufficient for a shift of spatial attention). Thirdly, planning a goal (...) directed action with any effector system is sufficient to trigger a shift of spatial attention. Fourthly, the eye-movement system has a privileged role in orienting visual spatial attention. This article reviews empirical studies that have tested these predictions. Contrary to predictions one and two there is evidence of anatomical and functional dissociations between endogenous spatial attention and motor preparation. However, there is compelling evidence that exogenous attention is reliant on activation of the oculomotor system. With respect to the third prediction, there is correlational evidence that spatial attention is directed to the endpoint of goal-directed actions but no direct evidence that this attention shift is dependent on motor preparation. The few studies to have directly tested the fourth prediction have produced conflicting results, so the extent to which the oculomotor system has a privileged role in spatial attention remains unclear. Overall, the evidence is not consistent with the view that spatial attention is functionally equivalent to motor preparation so the Premotor theory should be rejected, although a limited version of the Premotor theory in which only exogenous attention is dependent on motor preparation may still be tenable. A plausible alternative account is that activity in the motor system contributes to biased competition between different sensory representations with the winner of the competition becoming the attended item.

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)

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.
