This study intends to analyze Joyce`s attitude against the nationalistic notions of the Celtic twilight. In his terms, they are characteristic of anti-Semitism, imperialism and cultural provincialism. He is harsh with nationalism. But peculiarly in his criticism he often superimposed excrements on the professed high sentiments of nationalism. With such superimposition did he work out comic effect. The comedy enables us to feel convinced with mirth of his criticism when the nationalistic movement was criticized as `cultic twalette` that implicates the Celtic twilight overlaid with cul toilette. Therefore, by criticizing nationalism with the stylistic use of superimposition, he led his contemporaries (or us readers) to the realization of their aberrant notions of nationalism. That is why we can acknowledge his own nationalism
