The Danger of Wisdom (Ecclesiastes 7:15-29)

We know that the beginning of wisdom is the fear of the Lord.  If we are consistent it would seem that it is better to go through life being wise rather than being a fool.  So, why does the preacher warn us not to make ourselves too wise?  Is he contradicting the wisdom tradition or is he communicating something that is essential for us to remember as we pursue wisdom?
