I didn't link anything because I am using a copy of Psychological Types that is sitting on my desk. The cognitive function quote is from the cognitiveprocesses.com site.
I feel Jung's quote does clarify, which is why I posted it (apparently it did, based on your new post). I like to support my thought with outside views for the very reason that I can easily pull shit out of the sky that has no basis in reality. I'd rather not fall into that trap, which I set for myself.
Of course you don't have to agree with any experts or me, but I am telling you I take their word over yours, and yes, it explains my mind much better than you are doing. I have repeatedly explained my viewpoint, much more so than knocking your credibility (you seem to be accusing me for exactly what you are doing to me, questioning my sources, asking about links, etc, which is fine, but it ignores my points). I'm not sure what you are not understanding about my viewpoint, or if we just plain disagree. I think it's a little of both.
Of course no function does anything exclusively, and it can be hard to separate each function from the whole type. I said in my last post that Fi needs an outlet, and that's just what my block quote from Jung is saying. I think we can agree there, but we'll have to disagree that Fi is not a source for original ideas, however broad or fuzzy they may be. Although, now you seem to see that it does have a visionary aspect.
Holds = contains, stores, organizes what already exists...it's not creative
Forms = shapes, makes, etc...it's creative
An idea is a view, belief, conception, etc.
I agree it takes more than one function to fully form an idea, but I think ideas may be linked to an internal or external source. I think that many Fi-doms have ideas that are internally sourced (which words like vision and phrases like primordial images support), which indicated they are born from Fi, even if Ne nourishes and pushes it out. There is that little Fi egg there to begin with, waiting for something to provoke it so that it forms into something recognizable that can stand alone externally. Sometimes ideas come from outside also, but a Fi-dom is usually more concerned with their internal self. Is there a whole lot of evaluating that goes on? Yes, and that's why Fi is called rational and Pi is not. I found Jung's description of Ni very interesting, but I do not relate to it for that very reason (it doesn't evaluate so much).
"Primordial image" references:
I can quote from the definition part of what primordial image is referring to, but I'd have to type it out and I don't feel like it right now.It [Fi] is continually seeking an image which has no existence in reality, but which it has seen in a kind of vision. It glides unheedingly over all objects that do not fit with its aim. It strives after inner intensity, for which the objects serve at most as stimulus.
The primordial images are, of course, just as much ideas as feelings. Fundamental ideas, ideas like God, freedom, and immortality, are just as much feeling-values as they are significant ideas.
