 Funkhouser’s (2006) property-space account (see his 2014 for further exposition) starts by filling in what it is to have a determinable “in a specific way” (Increased specificity) by attention to ‘determination dimensions’—features along which a determinable may be determined, such as, e.g., hue, saturation, and brightness in the case of color. The suggested methodology for identifying determination dimensions of a given determinable is broadly empirical, and involves inquiring after “the ways in which determinates under the determinable \(X\) can differ from one another with regard to their \(X\)-ness” (2006: 551), which suggestion picks up on both Determination ‘in respect of’ determinables and Determinate incompatibility.
