 That determinables and determinates may be jointly fundamental has implications for our understandings of fundamentality and metaphysical dependence. Fundamental entities are commonly assumed to be independent, in being wholly distinct, and (relatedly, as per ‘Hume’s Dictum’) in being such that each can either exist together or exist apart. But if determinables and determinates can be equally fundamental, this understanding is incorrect; for given the intimate relationship between determinables and determinates, to say that these are equally fundamental is evidently not to say either that they are wholly distinct or (even granting Hume’s Dictum) modally independent. Moreover, if determinables and determinates can mutually found each other, other stipulated suppositions are called into question—e.g., that the fundamental entities are those that do not depend on any other entities, and that metaphysical dependence is asymmetric.
