The reason why agency/structure and micro/macro debates remain unresolved i
s the bad essentialist habit of treating such pairs as opposite natural kin
ds. Once variation is allowed, agency and structure. or micro and macro, ar
e temporal? poles bracketing a continuum. with serial entities moving along
this continuum over time. Explaining these transformations from agency int
o structure, or micro into macro. and vice versa is the challenge for expla
natory theory. This challenge is met by switching to a constructivist level
of second-order observing. Then, agency and structure become variable devi
ces or frames different observers might use to perform different sorts of c
ultural work.
