Am I reading this wrong, in taking the words 'wisdom' and 'foolishness' to mean quantities of knowledge rather than opposites?
From Merriam-Webster Online Dictionary:
Main Entry: fool·ish
Pronunciation: 'f-lish
Function: adjective
1 : lacking in sense, judgment, or discretion
2 a : ABSURD, RIDICULOUS b : marked by a loss of composure : NONPLUSSED
3 : INSIGNIFICANT, TRIFLING
The first definition applies to a person who is foolish, not to the foolishness of wisdom. The second definition seems to be pertinent here and says that something that is foolish is not just wrong, but is absurdly wrong. The third definition seems to agree with your interpretation. So it appears that we're both right, both wrong, both wise, and both foolish. Anyone know what the original language text said and its possible interpretations?
