Joyce`s concept of "nat language" as not language has been understood as his way of interrogating language per se. But nothing can be politically neutral, considering the fact that Finnegans Wake was written during the Irish Civil War and then the implementation of a free state. Furthermore, Joyce`s last work is permeated by so many Irish historical events that we cannot discuss it without referring to them. One of the important historical events is the Gaelic League, an organization that led the bandwagon of Irish cultural nationalism. As an Irish writer and a colonized subject of the British Empire, however, Joyce must have inevitably been ridden by the controversial agenda of reviving the "native" language, and have found it difficult to keep totally aloof from the debate. In the post-colonial era, many newly independent nations made efforts to revive their own languages and at least to make them "official" languages. Ireland also officialized the Irish language with English with the advent of a new nation in 1921. Throughout his career as a writer, Joyce never forgot the significance of language in constructing a national or racial identity. Such a belief leads him to incessantly interrogate the efficacy of language as a communicative means within the national conflict of building a new free state. By dismantling the binarism of "native" language, Joyce seems to admit that his "acquired" language is unavoidable. Although his English is "secondmouth language," it is also "nat language," a language acquired in the historical moments where he is fatalistically positioned. Finnegans Wake is a result of Joyce`s guerilla war against both his "native" language and "nat language" by multiplying or confusing the "origins." It could be an answer to those writers whose colonial experience always pits them against their obligation for using their "native tongues," not colonizer`s language.
