Knowing can facilitate the refinements needed to explore diverse routes of thinking. I think in that sense knowledge can serve a valuable purpose.
I'm pretty sure I agree with this at times, it is very reflective, and I could be entirely wrong in my mental picture of what you are referring to.. This process of revealing, bringing into consciousness, is a way to explore a dynamic and changing stream of experience. It can be either a hindrance or virtue I think, as you can be faced with indecision as a result, but if you built a dynamic and robust knowledge and came to this revelation naturally it can promote perspectives that overcome the boundaries of your knowledge. Hmm.. (?)
