From a google group discussion post,
An oft-told example illustrates the relationship of the two virtues of Wisdom and Compassion. Suppose you are approached by a homeless person asking for a handout. You give him some money – which he promptly spends on alcohol. You have been compassionate, but not wise. So the next time you are approached, you give nothing; now you have been wise, but not compassionate. What is the solution? Buy him some food. This is wise and compassionate. Compassion without wisdom is foolish; wisdom without compassion is harsh. As every good parent knows, the two must be used in balance.
