 Johansson (2000, 2004) endorses a constitutive account of determinables—more precisely, of ‘maximal’ determinables (such as color, shape, and smell) located at the top of a determination hierarchy—taking Determinate similarity and Determinate gradability as its starting point. It is, he says, characteristic of determinables and determinates that “two different determinates of the same determinable can always be continuously connected” (2000: 108), in a way providing the basis for the gradeable resemblance of the determinates. Conversely, Johansson maintains, determinates under wholly different determinables are not connected in this fashion: “No color-determinate resembles more closely a shape-determinate or volume-determinate than any other” (2000: 108). This ‘gap’ between determinables acts as a criterion, whereby a determinable is posited if and only if there is such a gap—hence it is that only maximal determinates exist, by lights of Johansson’s criterion. In cases where a determinable is appropriately posited, the determinable is shared by its determinates and explains their similarity; for example, all color-determinates have the determinable property color in common (Johansson 2000: sec. 3). Johansson’s view is a mixed eliminativist/non-reductionist view, since he assumes that any non-maximal determinables do not exist, but are merely “man-made constructions” (2000: 113). Such a view is unmotivated, however, since even in the absence of a ‘comparability gap’ between same-level determinates (e.g., yellow and red, or yellow and scarlet), one might still suppose that the difference between yellow and red (or scarlet) is not a matter of convention. Another concern with Johansson’s account reflects that the mere posit of a shared determinable does not (as Bigelow and Pargetter [1990] and Massin [2013] have observed) in itself make sense of determinable differences, though perhaps the appeal to the ‘continuous connection’ between determinates can do some work here.
