Philosophers are accustomed to thinking about human existence as finite and death-bound. Anne O'Byrne focuses instead on birth as a way to make sense of being alive. Building on the work of Heidegger, Dilthey, Arendt, and Nancy, O'Byrne discusses how the world becomes ours and how meaning emerges from our relations to generations past and to come. Themes such as creation, time, inheritance, birth and action, embodiment, biological determinism, and cloning anchor this sensitive and powerful analysis. O'Byrne's thinking advances and deepens important discussions at the intersections of feminism, continental philosophy, philosophy of religion, and social and political thought.
