Transhumanists and their fellow travelers urge humanity to prioritize the development of biotechnologies that would eliminate aging, delivering ‘an endless summer of literally perpetual youth.’ Aspiring not to age instantiates what philosopher Martha Nussbaum calls the yearning for ‘external transcendence,’ or the fundamental surpassing of human bounds due to confidence that life without them would be better. Based on Immanuel Kant’s account of the parameters of human understanding, I argue that engineering agelessness could not be a rational priority for humanity (...) on the level of public policy. This stance is complemented by an argument focused on individual decision-making in liberal-democratic milieus, where no governing conception of the good is presumed and the first-personal level matters greatly. Here, drawing on philosopher and cognitive scientist Laurie Ann Paul’s concept of ‘transformative experience,’ I maintain that individuals could not ‘rationally,’ meaning, here, ‘prudentially,’ say ‘yes’ to agelessness. Absorbing the irrationality of human zeal to eliminate aging, based on assurance that an ageless existence would be better, should spur a redoubled dedication to human flourishing. (shrink)

The main objection to genetic enhancement is that it will create a “genetic apartheid,” deepening existing inequalities. This paper offers considerations that can weaken the inequality argument against genetic enhancement. First, I question the dichotomy of treatment versus enhancement since the differences between the two are unclear. Second, I argue that human enhancement is part of human nature and that there is no sound reason to accept it in other domains while rejecting it in genetics. The paper also demonstrates that (...) inequality is present in every dimension of society, that “God-given” genetics is profoundly unequal, and that genetic enhancement can operate as a mechanism by which a new genetic equality can be achieved. However, the paper underlines that genetic equality is not, per se, a value to which we ought to aspire if it leads us to a uniform community of downsized human beings. Genetic equality is only valuable if it enhances humankind in general. (shrink)
