Suppose you had the chance to save the life of one sparrow, but doing so kills you with probability p. For what values of p would you do so?
If the answer is only when p=0, then your value of sparrows should never affect your choices, because it will always be dominated by the greater probability of your own welfare.
A strong argument, well done.
This indeed puts me in a conundrum: If I answer anything but p=0, I'm giving a kind of weighting factor that destroys the supposedly strict separation between tiers.
However, if I answer p=0, then indeed as long as there is anything even remotely or possibly affecting my top tier terminal values, I should rationally disregard pursuing any other unrelated goal whatsoever.
Obviously, as evident by my writing here, I do not solely focus all my life's efforts on my top tier values, even though I claim they outweigh any combination of...
