Adversiting discourse is no longer marginal in the Joyce industry. In her heralding study, Advertising Fictions, Jennifer Wicke regards advertising as "an archive, in the Foucauldian sense." She also argues that advertising looks forward to "the death of the human subject." Here I will argue that advertising discourse is inseparable from other politico-socio-economical discourses, since advertising employs other discourses strategically and in turn they use strategic methods in promoting their ideas and practices. So I deal with the ways in which both Irish nationalist ideology and Catholic creeds are so interrelated to advertising that the borderline between "high culture" and "low culture" is being erased or at least incessantly being blurred. James Joyce`s childhood nickname was "Sunny Jim," a phrase from the jingle used in a cereal advertisement, since he was always a merry boy. In his Trieste library, a book titled The Art of Selling Goods, is a good example of Joyce`s interest in advertising. These may explain why Leopold Bloom, the main hero of Ulysses, works as an ad canvasser. On June 16, 1904, his main mission is to get a three-month renewal from his client, Alexander Keyes, whose ad he is working on. Bloom thinks that the ad of "the House of Keyes" has an "innuendo of home rule." In other words, he deploys political discourse in promoting his ad. In an ad printed in Shan Van Vocht, the advertised brooches and pins have a phrase, "Who Fears to Speak of `98?" This phrase is a reminder of the 1798 revolution led by Wolfe Tone, and this revolution is regarded as a starting point of militant nationalism throughout Irish history. Its other manifestations are the Phoenix Park murders in 1882, and the Easter Rising in 1916. The former is mentioned in a talk about Ignatius Gallaher`s "inspiration of genius" and the case of selling a 10-year anniversary postcard in the Phoenix Park. Both events are related to advertising and commodity culture. Adversiting trespasses the holy ground of religous discourse by stimulating people`s religious emotions and persuading them to buy something while religion cannot help using advertising strategies in order to sell religious creeds to non-believers. One of the most distinctive examples of the convergence of religion and advertising is American revivalist Alexand John Dowie`s throwaway, an advertising sheet. Alexander Dowie is presented as the modern-day Elijah with a commerical tinge. The efficacy of the Revelation is lost in the middle of commercial jargons. So the boundaries between advertising and religion is blurred or effaced. In Ulysses, James Joyce looks forward to the advent of new age, primarily based on capitalism and commodity culture. Advertising does not only play an important role in constructing the human subject in modern age, but also tears down any hierarchical system of discourses. Joyce regards advertising not only as the scene of writing, as Jennifer Wicke emphasizes, but also as the arena of competing discourses, in which the reader must actively participate, in order to get some meanings.
