1. Those who believe the world is the way they see it.

2. Those who realize how limited their perspective is.

That's a good point. I suspect that the first one isn't so much a lack of humility, though.

Naively, it seems that you're just perceiving how the world is, as if your eyes are just windows into the world, and that your judgments (e.g. such and such is being a jerk) are simply reflecting the objective nature of how things are.

It takes time, learning and effort to really become aware of your perception of things as something in itself, that it is a process which takes in limited information and makes judgments on the basis of various assumptions, and that it is something which can be turned in on itself in a critical fashion.
