After LifeLife is one of our most basic concepts, and yet when examined directly it proves remarkably contradictory and elusive, encompassing both the broadest and the most specific phenomena. We can see this uncertainty about life in our habit of approaching it as something at once scientific and mystical, in the return of vitalisms of all types, and in the pervasive politicization of life. In short, life seems everywhere at stake and yet is nowhere the same.
