There are many binary oppositions in To the Lighthouse. The representative one is male/female. They are all first unified, then deconstructed, and then finally denied. The female painter, Lily Briscoe, seems to embody Virgina Woolf"s androgyny, but in fact, she lacks not only masculinity but also femininity. Most previous studies of To the Lighthouse argue that this novel embodies Woolf"s ideal model, androgyny. However, Woolf shows that androgyny can be deconstructed and denied through the symbol of the waves, and the lighthouse itself. The waves contain both soothing and destructive impulses, in other words, femininity and masculinity. However, readers ultimately discover that the waves in the novel signify destruction as they reach the end of the novel. The lighthouse embodies masculinity and femininity. The light from the Lighthouse represents femininity, which is soothing and inspires hope like Mrs. Ramsay. The Lighthouse, itself, symbolizes masculinity because of its shape. The Lighthouse seems to represent to Mr. and Mrs. Ramsay a revelation, but it was too far and too controlling for Mrs. Ramsay, akin to masculinity, while it was really nothing when Mr. Ramsay gave it a closer look. Lily Briscoe finished her painting with "a line". The critics of the novel usually interpret "the line" as a unification or a balance between masculinity and femininity. However, the line, correctly interpreted, signifies a separation between male and female. She thinks of "a line" when she sees Mrs. Ramsay showing pity to William Bankes, who seems unnecessary and controlling to Lily. As she begins to separate male and female, recognizing that their differences are meaningless, she can finally finish her work. It was her own "revelation". This paper argues that this novel ultimately deconstructs and denies androgyny, which was Virginia Woolf"s ideal model. Woolf"s alternative ideal is art like literature and painting. "He" and "she" vanish; while words and paint remain.
