The style in which Portrait of the Artist as a Young Man is written has a different feeling in its stream of consciousness. I am comparing it to the type of stream of consciousness found in Mrs. Dalloway. In Mrs. Dalloway I would be reading and the point of view would jump from one person into another. It's as if you could jump into other characters' minds for that moment and listen to what they were thinking. We are privy to many opinions and ideas.
The emphasize changes in the Portrait of the Artist as a Young Man to one person, Stephen. Although I have not finished Portrait, we are primarily in Stephen's mind then out. When we are out of his head we get descriptions of what is happening around him. It seems like we are looking at the world through his eyes.
I don't know which style I like better but both are challenging to read. One last thought, I wonder if the gender of the writer had an influence on the way the stream consciousness was written. I know Woolf wanted to write a book in the manner in which a woman would think. Did Joyce have the same motivation? Did he want to model his writing after the thinking of a young man?
