Quantitative (Theoretical) Structures
Steiner (1988) defines quantitative structures as follows:
Theoretical structures allow one to shape and group instances; they are universals and so are generals that are independent of time and place. Although 'quantitative' in a common sense pertains to numbers, in its technical sense it involves extension. Generals independent of time and place are universal classes as so have range. 'All' is a quantifier. (p. 18, italics added)
