Divine. Right. You'd be surprised how many people do. Humans often learn from example, not by precept. And if the example is bad, that leaves a bad experience, then whatever teaching they say they may be expounding is regarded as a lie or a joke.
Can't argue with you there. Of all the races I've encountered in my universe, I've always been drawn to humans for their gung-ho sort of attitude. They're a very resilient lot.
