Intertheoretic Comparisons of Choice-Worthiness [chapter]

William MacAskill, Krister Bykvist, Toby Ord

In this chapter we consider the extent to which different theories are unit-comparable, and what makes them comparable when they are. We consider three arguments for the conclusion that intertheoretic comparisons are always impossible: the appeal to cases argument, the swamping argument, and the arbitrary unit arguments. We argue against all three arguments. We distinguish between structural and non-structural accounts of intertheoretic comparisons. We argue in favour of non-structural

We discuss a number of possible accounts of intertheoretic comparisons, ultimately arguing in favour of a 'universal scale' account.
