Let's see how a utilitarian dictator would arrange things for Adam, Eve, and Lilith. One heroic assumption that utilitarians make

is that you can actually compare happiness and misery across different people: In reality, brain scans are making this easier to do but it's still a lot of guess$-$work. Let's suppose that this utilitarian dictator has eight apples to distribute: The table shows the utility that each person receives from their first apple $($a lot$),$ but extra apples give less extra happiness $($apples give "diminishing marginal utility," in economic jargon$).$

$\backslash$table$[[$Utility per Apple,Adam,Eve,Lilith$],[1^{st},1,000,600,1,200],[2^{nd},140,500,200],[3^{rd},20,400,100],[4^{th},1,300,50]]$

a$.$ So$,$ if the dictator wants to maximize the sum of Adam, Eve, and Lilith's utility, how many apples does each person get?

Adam would get $$ apples.

Eve would get $$ apples.
