 However, the background theory of magnitudes as sui generis entities remains quite underdeveloped. For example, it is unclear what entities can be the “values” of a magnitude; whether there are analogues for magnitudes of logical operations like conjunction and quantification in the realm of quantities; and whether there are analogues for magnitudes of the comprehension principles characteristic of “abundant” conceptions of properties. It is thus not yet clear how much of a difference moving to a magnitude-based framework would require in theorising about naturalness.
