SENSORY Welfare Hedonism:
The number that measures how good someone's life is, for him, is the number that measures (in hedons) the amount of sensory pleasure his or her life contains, minus the number that measures (in dolors) the amount of sensory pain his or her life contains.
The number that measures (in hedons) the amount of sensory pleasure someone's life contains is equal to the sum of the numbers that measure (in hedons) the amounts of sensory pleasure in the episodes of sensory pleasure his or her life contains. (Similarly for sensory pain.)
The number that measures (in hedons) the amount of sensory pleasure in an episode of sensory pleasure is the product of the number that measures (in seconds) the duration of that sensory pleasure, and the number that measures (in ???) the intensity of that sensory pleasure. (Similarly for pain.)
"Attitudinal" Welfare Hedonism:
The number that measures how good someone's life is, for him, is the number that measures (in hedons) the amount of attitudinal pleasure his or her life contains, minus the number that measures (in dolors) the amount of attitudinal pain his or her life contains.
The number that measures (in hedons) the amount of attitudinal pleasure someone's life contains is equal to the sum of the numbers that measure (in hedons) the amounts of attitudinal pleasure in the episodes of attitudinal pleasure his or her life contains. (Similarly for attitudinal pain.)
The number that measures (in hedons) the amount of attitudinal pleasure in an episode of attitudinal pleasure is the product of the number that measures (in seconds) the duration of that attitudinal pleasure, and the number that measures (in ???) the intensity of that attitudinal pleasure. (Similarly for pain.)
"Both lives contain ten years of marital strife followed by contentment; but let us suppose that in the former, you regard your first ten years of marriage as a dead loss, whereas in the former you regard them as the foundation of your happiness. The bad times are just as bad in both lives, but in one they are cast off and in the other they are redeemed" (65-66).
Velleman: "structural" features of a life make a difference to overall welfare.
Question: What structural features?
One proposal: narrative structure. "...an event's place in the story of one's life lends it a meaning that isn't entirely determined by its impact on one's well-being at the time...And the event's meaning is what determines its contribution to the value of one's life. (63)
The "narrative" theory of welfare: X's life is better (in the welfare sense) for X than Y's is for Y if and only if X's life makes for a better story than Y's.
What about the role of redemption?
