Although To the Lighthouse is a radical departure from the nineteenth-century novel, it is, like its more traditional counterparts, intimately interested in developing characters and advancing both plot and themes. Woolf’s experimentation has much to do with the time in which she lived: the turn of the century was marked by bold scientific developments. Charles Darwin’s theory of evolution undermined an unquestioned faith in God that was, until that point, nearly universal, while the rise of psychoanalysis, a movement led by Sigmund Freud, introduced the idea of an unconscious mind. Such innovation in ways of scientific thinking had great influence on the styles and concerns of contemporary artists and writers like those in the Bloomsbury Group. To the Lighthouse exemplifies Woolf’s style and many of her concerns as a novelist. With its characters based on her own parents and siblings, it is certainly her most autobiographical fictional statement, and in the characters of Mr. Ramsay , Mrs. Ramsay , and Lily Briscoe , Woolf offers some of her most penetrating explorations of the workings of the human consciousness as it perceives and analyzes, feels and interacts.
