Two quotes for TWOsday

Let's discuss these quotes:

(1)  "How many oceans are there?  If you did well in middle school geography class, you probably answered 'five':  Pacific, Atlantic, Indian, Arctic, and Southern.  But wait!  That's not quite right.  Five is the cultural answer, based on our twist of reality.  The correct answer — nature's answer — is just one.  Look at a globe if you don't believe me; we live on a one-ocean world."

That's from page 182 of 50 Popular Beliefs That People Think Are True by Guy P. Harrison (2011).  Do you agree?  Looking at the map, would you say there are five oceans or one ocean or something else?

(2)  "I wanted real adventures to happen to myself.  But real adventures, I reflected, do not happen to people who remain at home:  they must be sought abroad."

That's from page 12 of Dubliners by James Joyce (1914).  What's a "real adventure" for you?  Do you think we need to go "abroad" to find adventures?  I seem to find them wherever I am, but maybe I don't define adventure the way James Joyce does.
