Knowledge is relevant to where you are on your life’s path and course and within your field of action and experience. The reason the high schooler is “more knowledgeable” than the preschooler is not that the former’s knowledge is “higher” or “superior”, but that the high schooler has more responsibilities and experience at his or her stage in life and therefore needs a larger skill set. So you have appropriate knowledge for you at this time in your own evolution and so do I and as we evolve, we evolve to different states of knowledge consistent with the evolution. I call it the Jacob’s Ladder principle.
I know things a farmer does not know, but the farmer knows how to grow food. Which is higher? It depends. Are we hungry?
