Wisdom is a spiritual truth to which we posses with our experience, using our experiences as guides. What convinces us to believe this or that? Again I believe it is our heart which is our emotional center of our true nature. Philosophy is our study of others and their actions and beliefs.
One cannot believe without knowledge from others. Is it free will when we decide to believe or the knowledge from the original source? Is wisdom by experiences or observation? How can the words I love you convince you I do? Can we put our emotions into our words? Can we also add the word wisdom to that question?Paul
