Bliss?

Ecclesiastes 1:18
For with much wisdom comes much sorrow; the more knowledge, the more grief NIV

Or in the the NASB
For in much wisom is much vexation; and he who increases knowledge increases sorrow.

Ecclesiastes always has some sort of fascination for me, I don't know why. These verses in paticular I keep tumbling over in my mind. Maybe it's a key to frustration I seem to regularly feel with the world and with myself (coupled with Romans 7 of course). I don't know, but it does seem to support the idea that ignorance is bliss.

The question is, are we doomed then if we want wisdom? Is happiness an indication of idiocy? I would hope not, yet this makes me wonder. Maybe I'm just moody as I write this. I would hope so anyway, as the opposite is very despressing.
