Ah, thank you for deepening historical precedent. Should I get
   the inkling later, I may follow the breadcrumb trail. [yes, I'm
   on a search for conceptual-basis (es) of concepts. Similar to
   etymology but a little more woobly than that... although it's
   probably still etymology and my awe is what's making the
   woobly). ]wrt my search for concept of necessity: Ananke
   (necessity) in classical Greece, 5th century BC. Aditi, karma,
   and dharma in the Vedas, 15th century BC. And necessary is
   anything but a metaphor in logic theory. I don't think there are
   metaphors in logic. Economics, though very old, is not the
   oldest discipline to give serious context to necessity. - via
