 Why accept OD7? In certain cases, overdetermination strikes us as an overt violation of Ockham’s Razor: do not multiply entities beyond necessity. But given the intimate connection between baseballs and their atoms, it is natural to feel that even if these do count as cases of overdetermination (in the indicated sense), this isn’t an especially objectionable sort of overdetermination. One may then attempt to resist OD7 by articulating a further condition which distinguishes problematic from unproblematic cases of overdetermination. For instance, one might hold that overdetermination by o1 and o2 is unproblematic so long as o1 and o2 aren’t entirely  independent.[46]
