I've always wondered about the black/white mentality, and wondered if it has
been influenced at all by the way travel has developed. That is, if you use
a road, or tracks, you have a definite left side and a right side -- as
opposed to riding or walking, which is usually just going wherever looks
easiest or nicest, not in a straight line. I think if you ride/walk you
have a more unified view of the world. I'm not very good at relating my
thoughts. But anyway, I think many people nowadays don't realise they have
this split vision of the world because they've always traveled by road,
sidewalk, tracks -- anything that seeks to make order out of the human need
to get somewhere. And roads are so huge, long, and straght they can divide
the world from horizon to horizon.
