Abstract Objections to life extension often focus on its effects for individual well-being. Prominent amongst these concerns is the possibility that life extending technologies will extend lifespan without preventing the ageing of the mind. Writers on the subject express the fear that life extending drugs will keep us physically youthful whilst our minds decay, succumbing to dementia, boredom, and loneliness. Generally these fears remain speculative, in part due to the absence of genuine life extending technologies. In this paper, however, I (...) examine the implications of an existing life extension technology. Caloric restriction (CR) and drugs that mimic its effects, such as rapamycin, metformin and resveratrol have been shown to increase average and maximum lifespan in a wide variety of organisms, and seem likely to do so in humans. Moreover, some CR mimetic drugs (CRMs) are already widely used. This means that they present a pressing test case for fears about mental ageing in an extended life. Misgivings about mental ageing can be divided into biomedical factors such as the likelihood of brain ageing, and psychological factors such as loss of meaning and boredom. I argue that studies of CR suggest that brain ageing will be beneficially slowed. However, it is less clear that deleterious aspects of psychological ageing can be similarly retarded. I argue that this reduces the desirability of life extension unless major social changes can be made. (shrink)

We often talk and behave as if being a man required more than just being male, and being a woman required more than just being female. There are expectations that need to be met if someone wants to fully qualify as a man or a woman in their social environment, expectations regarding their behaviour as well as character. It is, however, not entirely obvious what ‘being a man’ or ‘being a woman’ actually means and in what way and to what (...) extent it defines our identity, making us who we are. Would I be a different person if I were a woman? And what would it take for me to be a woman? Could I conceivably be neither? Or both? If gender were nothing but sex, telling a man to ‘be a man’ would make little sense. We may have different ideas about what it means to be a man or woman and how we need to behave in order to secure or maintain our manhood or womanhood, but we are all likely to have some deeply ingrained understanding of what makes a man a man and a woman a woman that goes beyond mere biology. Does it, however, follow that gender can, if necessary or desired, be completely detached from sex, that I can be a woman despite having all the physical attributes of a male member of my species, or a man despite being biologically female? If so, on what grounds exactly would we decide who is what? (shrink)

“Historicity” describes the human condition during one’s life course, marked by contingency and freedom, temporality and finitude. The concept also occurs in evolutionary biology, social sciences and psychology, highlighting history and context. Hannah Arendt situates the capacity for new beginnings at the essence of human beings (natality), allowing for new generations. Transhumanist narratives are shown as foreign to the concept of historicity due to a view of human nature, the load of accumulated past, and directed evolution. Finally, the “back to (...) dust” motif is related to finitude, suggesting that new technologies may move us away from humanness. (shrink)

El movimiento transhumanista tiene, entre sus propuestas principales, el proyecto de alargar la vida para poder alcanzar la inmortalidad en una vida indefinida o en una forma cibernética de existencia. En este artículo se presenta la propuesta del transhumanismo y se reflexiona sobre el deseo de ser inmortales y sobre las implicaciones antropológicas de la muerte. La crítica se hace desde la consideración de aspectos fundamentales del ser humano, como la finitud, la historicidad y la vulnerabilidad. Además, el proyecto transhumanista (...) de vencer la muerte supone una propuesta de salvación, que coincide en su formulación con la misma que hace el cristianismo. Ambos pretenden una victoria sobre la muerte. La crítica teológica se centra en la comprensión de la muerte y en la reflexión sobre los medios para vencerla. En este artículo la crítica al proyecto transhumanista se dirige, más que a lo que propone, a lo que queda sin plantear, provocando una reducción en la comprensión de la muerte y en la forma de vencerla.
