the happy little slugbug

A conversation with a friend of mine got me thinking....

He said-- "some people are very intelligent with the match tendency to doubt and criticize. Such a person is powerful, but with powerful engines, requires a lot of fuel to maintain a happy amount of energy. A smaller engine, may not see or know much, but is quite happy in ignorance of all things, and requires little fuel to sustain"and I said okay i guess, but I didn't like the idea that the little guy was happier just because he didn't know any better.
So, I'm thinking, what if there are levels? What there's the little slugbug level where he's happy just because he doesn't know any better. Then there's the SUV level or whatever where he's having a harder time being happy 'cuz he's learned some stuff. What if after that there's another level (um.... anologie [too late to splele that word!] difficulty-- airplane????), where the guy has learned even more, but because of that finds it easy to be happy.
I guess that's what I disliked about the little car being the happy one-- Knowledge should make us happy. Or rather, the more Truth we know, the happier we will be because, honestly, the Eternal Truths are pretty awesome, exciting things. They shouldn't get us down.If all we know is getting us down, perhaps we're not seeking after or focusing on the right knowledge...or something like that.
