Socrates on wisdom –
“Well I am certainly wiser than this man. It is only too likely that neither of us has any knowledge to boast of; but he thinks that he knows something which he does not know, whereas I am quite conscious of my ignorance. At any rate it seems that I am wiser than he is to this small extent, that I do not think that I know what I do not know.” ~ Socrates

My 2 cents
With that quote, I have to say…
“I know enough to know when I don’t know everything about something, but I have the capacity to learn new things.  When I learn something well enough to teach it to others, I have gained an understanding or “wisdom” that has value to others.” ~ Del Wright
