Dorothea is an earnest intelligent woman who makes a serious error in judgment when she chooses to marry Edward Casaubon, a pompous scholar many years her senior. Dorothea hopes to be actively involved in his work, but he wants her to serve as a secretary. She comes to doubt both his talent and his alleged magnum opus. Furthermore, the controlling Casaubon becomes jealous when she develops a friendship with Will Ladislaw, his idealistic cousin. Although disappointed, Dorothea remains committed to the marriage and tries to appease her husband. After Casaubon has a heart attack, Dorothea is clearly devoted to him, but he bars Ladislaw from visiting, believing that his cousin will pursue Dorothea when he dies. Casaubon subsequently seeks her promise that she will follow his wishes even after his death. She delays answering but ultimately decides that she should agree to his request. However, he dies before she can tell him. Dorothea later discovers that his will contains a provision that calls for her to be disinherited if she marries Ladislaw. Afraid of scandal, Dorothea and Ladislaw initially stay apart. However, they ultimately fall in love and marry. Ladislaw later becomes a politician, and, despite her sacrifices, Dorothea is content, because “the growing good of the world is partly dependent on unhistoric acts.”
