 We conclude this section by posing a further question to all proponents of  (RI):  what is it that privileges the proper subset of metaphysical dependence relations that are relevant to fundamentality, be there one or many of them? What makes these dependence relations relevant for fundamentality? Given that one major task for the notion of fundamentality is often thought to be related to the idea of the hierarchical structure of reality, one potential starting point might be to appeal to asymmetry and transitivity, but we have seen that there may be relations of dependence that are relevant to fundamentality that fail to be transitive. At this point, it may be helpful to move on to the third potential definition of fundamentality, as something along the lines of this definition is often used to characterize fundamentality defined in terms of (RI) as well.
