In the comments of the post below, "In a Nutshell," Alison Croogon wrote the following inspirational sentences:
"Yes, of course artists have to be intelligent, but that is not by any means the whole of what's required...Artists are not only concerned with ideas, but with responding to the world around them through the sensual media they use - words, paint, rock, their bodies - in ways which bypass cerebral thinking, which focus on the materiality and sensual properties of the things they use, and which seek emotional as well as intellectual response."
That is as close to a perfect definition of what I mean by wisdom as I am likely to find. To improve on it would only be to add more details to the basic idea that wisdom is the ability to see, appreciate, and express as much of the world as possible using as much of one's self as possible: the intellectual and the emotional, the cerebral and the sensual, the comic and the tragic, the just and the unjust, the heroic and the cowardly, the love and the hate -- the list could go on, of course. But to me wisdom is the embrace of all the possibilities of the world, and express them in such a way as to guide others to see them as well.
Thank you, Alison!
