Why the Hegelian Triad Is Not Sufficient
Hegelian ethical life is conceptually complete—family, civil society, state—and yet its application reveals something Hegel himself did not work out: ethical life appears historically in qualitatively different constitutions, and the difference between these constitutions is not already captured by the triad of family/society/state.
This is no objection to Hegel but a consequence of his own method, once that method is understood heuristically: whoever takes logic not as derivation but as an ordering achievement must expect that concrete application will introduce differentiations not yet worked out in the movement of the concept.
