“You were asking about the happy people: Well, they don't live on our planet, you see; we'll just have to wait, my boy! On this one human beings are not human beings. They are seamen and farmers and miners and lumberjacks; they are tramps and preachers and professors; they are this and that and the other. And happiness departed from them when they left off being human beings and became this other; for then strife began.” 

― O.E. Rolvaag, Boat of Longing
