What are the motifs in Burger's Daughter by Nadine Gordimer?

Developing a sense of personal identity is a recurring idea in the text. Rosa is a person who inherits a revolutionary identity from her father and mother. She has to decide if she wants to make this identity her own. Her lover and then pseudo-brother Conrad argues that Rosa does not have an identity and is just a brainwashed victim of her parents' politics. At a certain level, Conrad's ideas appeal to Rosa, because they give her the excuse she needs to stop being active in the networks of the Communist Party and the ANC.
