 With this latter claim, Funkhouser’s account moves into ontological territory, and might be plausibly seen as a sophisticated variation on a disjunctivist or other reductionist theme—say, one elucidating the internal dimensional structure of determinate disjuncts vis-á-vis associated  determinables.[32]  In any case, as with reductive accounts, Funkhouser’s assumptions that reality is ultimately maximally determinate and that determinable and determinate instances are token-identical are subject to challenge as either empirically inadequate or such as to not properly accommodate the perceptual and other motivations for determinables. That said, it seems likely that the structural aspects of Funkhouser’s approach could be preserved even if these assumptions are relaxed, such that, e.g., ‘points’ in a property space aren’t taken to correspond to maximal determinates (see note 45).
