I think Solomon was wrong on this one.

I think the mere fact that Solomon himself was remembered as a really wise man proves this wrong.  How many fools from Solomon's generation do we remember by name? 

Ecclesiastes 2:16(NKJV)

    For there is no more remembrance of the wise than of the fool forever,     Since all that now is will be forgotten in the days to come.     And how does a wise man die?      As the fool!
