In this essay I propose an alternative theoretical framework for explicating human enhancement. The framework is based on the concepts of reciprocity, which I consider a fundamental aspect of human presence, and of mediation, which I consider a fundamental aspect of the relation between human beings and science and technology. I argue that enhancement is given by the way in which technological and scientific mediation alters the structure of the network of reciprocity characterising human presence. As a matter of fact, (...) technological mediation may turn the reciprocity of presence into a unilateral relation, which prevents any form of response. The lack of responsibility, here understood as the possibility to respond back, is determinant for the generation of a situation of power and for eliciting moral disengagement. The framework will be applied and discussed with reference to robotics technologies. (shrink)

At the present time there is a boom in the use of pharmacological cognitive enhancers (PCEs) particularly within an academic and labor context. Numerous objections to the use of this medicines arise in the context of Neuroethics, being one of the most important, the principle of justice. Among the most prevalent arguments put forward it is noted the disturbance of distributive justice and competitive fairness. -/- Succinctly it is established that hypothetical PCEs without adverse effects could promote the social fragmentation (...) by favoring economically dominant classes. However, it has been experimentally observed that PCEs present benefits ruled by the inverted U phenomenon, where cognitive benefits given by these medicines are not dose-dependent and have dependence on the baseline performance. Producing bigger benefits in individuals that initially had a worst performance. In this way the use of PCEs, assuming a context of open-access, could contribute to social equity and distributive justice. (shrink)
