Kinda continuing discussing of how classic electrodynamics follows from quantum one. I was always wondering myself what is more fundamental of the "trinity" (=charge, field, virtual carrier)? My feeling is that electric charge is the one which is "responsible" for virtual photons (bunch of which is basicly what we label as "electric field"). Or can "field" be postulated and then both electric charge and a virtual photon (field state) derived ? Or can everything be derived from postulating a virtual photon (some call them DC photons, by the way) to be a fundamental entity? Anybody willing to toss/kick opinions or "established views" around?
