James Joyce addresses his calling as an artist through the parable of water in the “Ithaca” episode of Ulysses. An idealistic concept of an artist is in the harmony of the opposites. In other words, an artist has the ability to grasp the similarities between seemingly conflicting qualities. Furthermore, the artist has the ability to connect the opposites; as currents of water flowing from all directions meet in the sea, the artist is able to blur all kinds of boundaries. This attribute of water or Nature is reflected in the characterization of Bloom, his opinion of Molly, and even in the narrative style of “Ithaca.” The author also considers vulgarity along with economic and sexual interests as innate traits of human beings. The characterization of Stephen or Bloom may indicate Joyce’s internal struggle between materialistic concerns and transcendental ideals. While Bloom mentally roves in regard to Molly’s adultery, his consciousness embodies the rhythms of nature: the rhythms of sexual organs or of the heart, which pumps blood throughout the body. He finally makes peace with conflicting pairs-such as the body and the spirit, the real and the ideal-in that process. Bloom comes to life as an artist again by accepting Molly’s sexual energy and by confronting human conditions as they are. Joyce presents a portrait of an artist who is the most realistic and sincere in history through the parable of water or the order of Nature.
