Dr. Stockmann: "the strongest man in the world is he who stands most alone." (5.310)
This is one of Ibsen's more famous quotes. You can find this sentiment in almost all of his plays. His work almost always tells the story of an individual attempting to establish a distinct identity in the face of tremendous societal pressure. Whether it's Brand, Hedda Gabler, or Nora Helmer of A Doll's House, almost all of Ibsen's protagonists are loners in some way. Ibsen's heroes and heroines tend to constantly seek a way break the rigid societal rules that bind them.
