[The X Phial]

I would have to say that changes brought about through hardship and suffering are different from a sudden realization, but I agree that each character probably has a moment in the book when they redefine something that used to be normal to them (except perhaps Gandalf, as you said). I have always thought of a paradigm shift as being on the large scale, i.e. the shift from religion to science as the dominant way of defining the world. I suppose the concepts are connected, though I think of mooreeffoc as being more like the "reframing" done in cognitive therapy.
