 In response to Whitcomb's penetrating criticism, one could argue that a deeply depressed person who is wise, would still live as well as she can, and would still value living well, even if she falls far short of perfection.  Such a person would attempt to get help to deal with her depression.  If she really does not care at all, she may be very knowledgeable, but she is not wise.  There is something irrational about knowing how to live well and refusing to try to do so.  Such irrationality is not compatible with wisdom.  A person with this internal conflict may be extremely clever and shrewd, one to listen to on many issues, one to trust on many issues, and may even win a Nobel Prize for her intellectual greatness, but she is not admirable enough, and rationally consistent enough, to be wise.  Wisdom is a virtue and a way of living, and it requires more than smart ideas and knowledge.
