 (RI) is restricted to concern only some specific kinds of metaphysical dependence, because it is plausible that some metaphysical dependence relations, such as modal dependence (as we saw in  section 1.1),  would immediately rule out fundamental entities. Notice that (RI) still includes the possibility of including several dependence relations, but we can easily define a restricted sense of dependence for each of \(D_{1}\), \(D_{2}\) … \(D_{N}\). We may also define a much weaker sense of restricted independence, call it some-independence:
