Wisdom is knowing there are 360 degrees of viewpoints, all being slanted in one's favor. To assume there is only one side is foolish; to accept a story without reserve is also fool hardy, and to denigrate another because of one viewpoint over another is the epitome of  ignorance. 

Wisdom is cultivating equal understanding (compassion) for all and holding this truth uppermost in one's mind -- that there is no way one could grasp the entire scope of a person by looks or superficial interaction alone. It would take a great many years to truly "know" a person, if that is ever possible and if one delves deep enough, they find all people are essentially of the same material- a spirit seeking happiness and having had some experience of suffering, therefore reaffirming the need to practice compassion equally.
