Hello Dick: I can understand why you would have a paranoia moment; but I also wouldn't think that's the end-all, nor am I bothered by it, for one, and if it means anything to you.
Also, you say: "Each person has the potential for appropriating and affirming the dynamic structure of his or her knowing and doing, even without having read, or even heard of, Lonergan."
This is quite true, and even germane to Lonergan's own work--it's not about the concept, or applying a method, but about the internal experience, and then the "appropriation" and affirmation of that experience as a "heightening."
From my view, however, we don't want to dispense with Lonergan's work. Philosophical problems come to us "in the air" of our educational history. Unfortunately, we get themas parasites before we are critical enough to filter them out. So that it's Lonergan's theory development, and his understanding of the "peculiarity" of cognitional theory (in Insight) that makes the difference and that signals a slow-in-coming paradigm shift in our philosophical understanding. Further, it's not merely a psychological/individual/isolated event, as we tend to read it in today's environment.
The difficulty is that, unlike how we understand most other studies, how we understand philosophical issues, even theoretically, already correlates with one's present philosophical demeanor; but that demeanor is either synthetic or conflicting with the actual interior structure (of all human beings) and its concrete activities. As conflicting, it's over and above that basic structure and its otherwise-resonant functioning. The resultant polymorphism (from the conflict) and then the taking and expression of poorly-wrought but (to us/them) logical philosophical "positions," presents us with all sorts of blocks to a truly (self-affirmed) empirical base for critical self-understanding.
