In this chapter, I propose the mechanism of cognitive enhancement based on studies of cognitive-enhancing drugs and behavioral training. I argue that there are mechanistic differences between cognitive-enhancing drugs and behavioral training due to their different enhancing effects. I also suggest possible mechanisms for cognitive-enhancing drugs and behavioral training and for the synergistic effects of their simultaneous application.

In recent years a large empirical literature has appeared on suffering at the end of life. In this literature it is recognized that suffering has existential and social dimensions in addition to physical and psychological ones. The non-physical aspects of suffering, however, are still understood as pathological symptoms, to be reduced by therapeutical interventions as much as possible. But suffering itself and the negative emotional states it consists of are intentional states of mind which, as such, make cognitive claims: they (...) are more or less appropriate responses to the actual circumstances of the patient. These circumstances often are such that it would rather be a pathological symptom not to be sad and not to suffer. Suffering, therefore, is sometimes and to some extent a condition to be respected. Although I do not dispute that the alleviation of suffering is the main aim of palliative care, in pursuing that aim we should acknowledge a constraint of realism. (shrink)

In this chapter, I consider the idea that physician-assisted death might come into question in the cases of psychiatric patients who are incapable of making autonomous choices about ending their lives. I maintain that the main arguments for physician-assisted death found in recent medical ethical literature support physician-assisted death in some of those cases. After assessing several possible criticisms of what I have argued, I conclude that the idea that physicianassisted death can be acceptable in some cases of psychiatric patients (...) who lack autonomy ought to be taken into account in assessing the moral and legal acceptability of physician-assisted death.
