What is wisdom?
To be wise is to be unequivocally good. Wise men are perceived to make correct judgments most of the time, and though wise men may fail to perceive one or two details that result in incorrect decision making, wisdom itself is never seen as its cause. In addition, the wise are never seen as morally flawed; their wisdom only leads to morally correct pronouncements.
Thus it seems to me wisdomis not a quality. It is a perception we grant to those we deem correct.
