Mortality, Meaning, and the End of Philosophy

This paper examines the transhumanist prospect of abolishing death and argues that technological immortality would undermine the conditions that make meaning and philosophy possible. Mortality is a biological limit but also the existential horizon against which identity, value, and narrative coherence are constituted. If death were eliminated, the structures that orient personhood, ethics, and motivation would be destabilized, along with the urgency and depth that characterize human life. The argument directly relates to current debates in AI ethics, bioethics, and technoethics, as the pursuit of digital or biotechnological immortality raises questions about personhood, embodiment, responsibility, and the moral limits of technological intervention. The central claim is that the very practice of philosophy presupposes mortality as its constitutive horizon, such that removing it would deprive philosophy of its central subject matter. The argument unfolds in three steps. First, it shows that life’s narrative coherence depends on finitude, for without an end, a life cannot take shape. Second, it claims that moral and communal values such as legacy, sacrifice, and generational concern rest on mortality. Third, it considers how the scarcity of time gives urgency to reasoning and commitment. Without temporal limits, projects can always be deferred, eroding their significance. Philosophy has long drawn its seriousness from the confrontation with death, from Platonic Socrates’ practice to modern existentialism. I conclude that transhumanist immortality would not extend philosophy but radically transform or undermine it, since the existential tension supplied by mortality has been indispensable to philosophy.
