I'm currently reading a fascinating book. It's entitled: Wisdom: A History. It's written by Revor Curnow, who is a professor of philosophy at the University of Cumbria in England. The book discussions wisdom as it is seen through very areas: literature, history, spirituality, etc. But the one thing that Curnow emphasizes early in this book is that there is no "universal" definition of wisdom that every agrees to. Yet, we are all able to identify wisdom by a certain set of characteristics.
I never really thought of wisdom like that. Yet it makes sense that there isn't an official definition of wisdom that all agree to. But yet we always usually describe wisdom through a particular set of characteristics. Just a little food for thought.
