Is the statement, "As the play progresses Nora learns a lot about herself," true?

The statement is very true. Nora's character is round and dynamic. This means that the perceptions, attitudes, behavior or beliefs of the character will change throughout the story, novel, or play. Main characters are usually round and dynamic. This is because the main problem of the story will likely have an impact on them that will result in change.

The statement is very true. Nora's character is round and dynamic. This means that the perceptions, attitudes, behavior or beliefs of the character will change throughout the story, novel, or play. Main characters are usually round and dynamic. This is because the main problem of the story will likely have an impact on them that will result in change.

Nora's character undergoes a change when her husband, Torvald, discovers the secret that she had been keeping from him: That she had borrowed money from a man in order to pay for medical expenses for Torvald. The act of doing such a transaction constitutes misconduct from a wife to her husband, at least during the time period when the play is set. However, Nora had internally wished to see a "miracle" unfold in case the secret is ever found out. She expected, or at least wished, that her husband would ignore the social conventions and praise Nora for this act. After all, she did it for him, and nobody else.

However, the exact opposite happens. Torvald is offended and mortified about what Nora did. He insults Nora and even says that she is an unfit wife and mother. Yet, after he finds out that Krogstad, his disgruntled employee and the man who loaned the money, will not blackmail them for the secret, Torvald immediately changes his tone and tells Nora that she is forgiven.

This was all Nora needed to see that her presence in the household for all these years had been simply ornamental; that her husband only expectation of her was for her to be a plaything, a doll, for his own entertainment. She also realizes that she had enabled such expectations by acting the way that Torvald wanted her to.

Another realization that hits Nora is that she has always been this way, even with her own father. That she has always sought her validation as a woman without avail, since the society in which she exists fails to recognize the efforts and sacrifices of her gender. This is when she decides that it is time to quit the charade that has been her life. She chooses to leave everything behind, even her children, and she walks out of her home for good, in hopes of perhaps finding herself one day.
