Is there more to how well a life goes overall (its lifetime well-being) than simply the aggregate goodness and badness of its moments (its momentary well-being)? Atomists about lifetime well-being say ‘no’. Holists hold that there is more to lifetime well-being than aggregate momentary well-being (with different holists offering different candidates for what this extra element might be). -/- This paper presents and defends a novel form of holism about lifetime well-being, which I call ‘End of Life’. This is the (...) view that the momentary goodness or badness of the end of lives has a disproportionate effect upon lifetime well-being. More precisely: a welfare subject’s level of momentary well-being at the end of their life contributes more to their lifetime well-being than their level of momentary well-being at each other point.
