Which two themes of o'neill's beyond the horizon are reflected in this excerpt from the play? robert: not so long when you come to consider it. you know the sunda sails around the horn for yokohama first, and that’s a long voyage on a sailing ship; and if we go to any of the other places uncle mentions—india, or australia, or south africa, or south america—they’ll be long voyages, too. andrew: you can have all those foreign parts for all of me. (after a pause) ma's going to miss you a lot, rob. robert: yes—and i’ll miss her. andrew: and pa ain’t feeling none too happy to have you go—though he’s been trying not to show it. robert: i can see how he feels. andrew: and you can bet that i’m not giving any cheers about it. (he puts one hand on the fence near robert). robert: (putting one hand on top of andrew’s with a gesture almost of shyness) i know that, too, andy. andrew: i’ll miss you as much as anybody, i guess. you see, you and i ain’t like most brothers—always fighting and separated a lot of the time, while we’ve always been together—just the two of us. it’s different with us. that’s why it hits so hard, i guess. robert: (with feeling) it’s just as hard for me, andy—believe that! i hate to leave you and the old folks—but—i feel i’ve got to. there’s something calling me—— (he points to the horizon) oh, i can’t just explain it to you, andy. importance of following one's dreams importance of family commitment attraction of the land versus the sea appearance versus reality attraction of people to farming
