There are matters that need knowledge to judge. If wisdom is knowledge, it can be taught. If it is not, it can’t be taught. Formalised methods of teaching wisdom are not available.
Wisdom involves the interaction of cognitive and emotional processes with social values. People seek wisdom through sage advice. Stories and fables convey wisdom. Wisdom is not necessarily conveyed through the content of a statement but through the way the statement is delivered. Wisdom requires experiential demonstration.
As the wise say, “One can have theoretical knowledge without any corresponding transformation of one’s personal being. But one cannot have wisdom without being wise.”
