 A further question concerns whether existing non-reductionist accounts of determinables can make sense of these being fundamental. On the face of it, there is no special difficulty with accommodating fundamental determinables on either powers-based or constitution-base accounts of determination, or with such accounts’ making sense of joint determinable/determinate founding. On Johansson’s (2000) account, for example, it might be that determinates depend on determinables in that the latter are constitutive parts of the former (nota bene: not obeying weak supplementation), and determinables depend on determinates in that, modulo gappy quantum indeterminacy  (see §5.3),  determinable instances must be parts of some determinate whole.
