What died with Dworkin & Coase?

Ronald Coase has passed away at the age of 102.  Earlier this year, another Ronald, Ronald Dworkin, also departed this vale of dissertations. What died with the two Ronalds?
I suppose it's the idea that the margin matters, what happens at the margin is always amenable to a globalized doctrine of harmonious construction such that no repugnancy attaches to what is novel nor can any revolutionary danger lurk in that marchland or beyond its equivocal pale.
Yet, phenotypal plasticity or 'capacitance diversity' must face epigenetic canalisation of some sort or other for Law and Economics to have a subject matter.
Still, if one had to choose a credo in which to grow old and merge imperceptibly into God's gloaming, one might go farther and fare worse than with the two Ronalds.
