Qualitative Structures
Steiner (1988) defines qualitative structures as follows:
Qualitative structures, if adequate, allow one to be sensitive to the immediacy of the given, to the uniques; they are pervasive qualities. Uniques cannot be members of classes and so no extension is involved; each is what it is. It cannot be said of a unique that it is one of a kind. No categorization is possible. (p. 18).
