Just wanted to chime in and say this is a very fun discussion to read. I’ve said this before but I think the ambiguity of the Force really adds to its mystique. I suppose out of universe George or JJ or Rian can say how they interpret the Force, but I think it would be to its detriment to ever definitively explain its function.
I think it would be cool to get an Old Republic story where we see opposing Jedi philosophies come to a head, not in a violent way, but where we see Jedi debate on the nature of the Force and the dark side. Maybe some Jedi see the dark side as an evil that needs to be purged, where others see it as an aspect of all life that needs to be understood.
