Helmer: Before all else, you are a wife and a mother.

Nora: I don't believe that any longer. I believe that before all else I am a reasonable human being, just as you are—or, at all events, that I must try and become one. I know quite well, Torvald, that most people would think you right, and that views of that kind are to be found in books; but I can no longer content myself with what most people say, or with what is found in books. I must think over things for myself and get to understand them.

–A Doll’s House,
Henrik Ibsen
