 There is an important corollary to drawing a distinction between intrinsic value and final value (and between extrinsic value and nonfinal value), and that is that, contrary to what Korsgaard herself initially says, it may be a mistake to contrast final value with instrumental value. If it is possible, as Korsgaard claims, that final value sometimes supervenes on extrinsic properties, then it might be possible that it sometimes supervenes in particular on the property of being a means to some other end. Indeed, Korsgaard herself suggests this when she says that “certain kinds of things, such as luxurious instruments, … are valued for their own sakes under the condition of their usefulness” (Korsgaard 1983, p. 185). Kagan also tentatively endorses this idea. If the idea is coherent, then we should in principle distinguish two kinds of instrumental value, one final and the other  nonfinal.[5]  If something A is a means to something else B and has instrumental value in virtue of this fact, such value will be nonfinal if it is merely derivative from or reflective of B’s value, whereas it will be final if it is nonderivative, that is, if it is a value that A has in its own right (due to the fact that it is a means to B), irrespective of any value that B may or may not have in its own right.
