Enriching Effects of Travel

I've been in Scotland now a week. As I am about to leave this country to head over to Ireland I've begun to reflect. I started to think about Scotland in the 1700s before there were cars, or planes or trains. I realized that for the common Scot back then they must have thought the existence of the Sun a myth like King Arthur. I don't see how any Scotsman could have every seen the sun without travelling off the island.
