Ibsen's letters, extending over a period of more than fifty years, provide us with a direct presentment of the man during the changing conditions of his life and of his friendships, and contain much, of both biographical and literary interest. They were written without any thought whatever of publication, and there is, therefore, nothing of the literary character about them - now they are ponderous, clumsy, official communications, now spontaneous, or even violent expressions of the feeling of the moment. But this very lack of literary finish endows them with the charm of real life, and makes them of inappreciable value as sources from which to derive knowledge of Ibsen. We have in these letters that unreserved expression of his personal feelings; we see him in his human weakness and greatness; we learn that his proverbial reserve is not in reality an essential element of his character; and a wonderful light is thrown upon the development of his theories of life and art, and upon the germination and growth and aim of his works.
Henrik Johan Ibsen was a major Norwegian playwright largely responsible for the rise of modern realistic drama. He is often referred to as the "father of modern drama." Ibsen is held to be the greatest of Norwegian authors and one of the most important playwrights of all time, celebrated as a national symbol by Norwegians.
His plays were considered scandalous to many of his era, when Victorian values of family life and propriety largely held sway in Europe and any challenge to them was considered immoral and outrageous. Ibsen's work examined the realities that lay behind many facades, possessing a revelatory nature that was disquieting to many contemporaries.
Ibsen largely founded the modern stage by introducing a critical eye and free inquiry into the conditions of life and issues of morality. Victorian-era plays were expected to be moral dramas with noble protagonists pitted against darker forces; every drama was expected to result in a morally appropriate conclusion, meaning that goodness was to bring happiness, and immorality pain. Ibsen challenged this notion and the beliefs of his times and shattered the illusions of his audiences.
