I am posting this so that I will can refer to it as seems helpful. The gist of it is that the less you know about a particular subject you are learning, the more you think you know. Conversely, the more you truly do know about a subject that you have studied for a lifetime, the less it seems to you that you know of all that there is to know. On the low end, it is sometimes expressed as "Truly stupid people don't know that they are." On the high end, I like to think of it as the humility of the wise. I wish that I had this new thread to refer to some weeks ago when I saw a comment to the effect that "Lee's low prices attract less intelligent people." Not saying that isn't true, BTW.
