the Ethiopians say that their gods are snub-nosed and dark, Thracians, that theirs are grey-eyed and red-haired.
Addendum: in comments, Michael pointed out to me that I didn't explain the duckrabbit illustration I used (the first pic in this post) so here it is. The duckrabbit is often used to demonstrate the way simple paradigm shifts happen. If you look at the picture thinking it's a duck, then you don't even notice it can also look like a rabbit, and vice versa. Because you're "in the grip of the picture" that you're looking at a duck. But once the idea occurs to you that it could be a rabbit, that's how you perceive it, and there seems to be no trace of duck left in it. And you can make it switch back and forth, thus experiencing a simple paradigm shift in your head in real time.
