Explanation:

"Beyond the Horizon" is Eugene O'Neil's play (1918). The play is about a farmer's family, specifically two brothers, Andrew and Robert Mayo; and their beloved Ruth Atkins. The basic theme of the play is importance of following one's dreams.

Andrew is farmer by nature, while Robert loves poetry, reading books, and daydreaming about adventurous journey to far off parts of the world. Physically, Andrew is strong and healthy while Robert is weak and sick. Andrew plays the role of a lover while Robert is portrayed as an ill-fated husband. Andrew is the one who takes real adventures, while Robert (though he loves adventures) because of his love with Ruth remains on the farm, is ruined and in turn ruins the whole family. Robert is almost free to take decisions whichever he like, whereas Andrew takes most of the decisions because of his brother, or because of the situation. Although Andrew sacrifices more, but it is Robert who has to suffer more.
