You might like to think about the way in which Chapter Five, the last chapter, represents a development of Stephen's role as an artist that he chooses in Chapter Four. In this last Chapter, Stephen comes to completely explore his understanding of being an artist. This is mostly achieved through the way that Stephen is shown to distance himself more and more from those around him as he embraces the role of solitary exile. This chapter actually contains a large amount of speech, more than other chapters in this novel, but we need to realise that the function of this dialogue is to demonstrate the way in which Stephen is becoming more and more distanced from his surroundings. In what Stephen says and how he responds to others, we can see the need of Stephen to court isolation and to escape the various "nets" of nation, family and religion that threaten to enmesh him. Consider, for example, his conversation with his Physics tutor when Stephen becomes more and more aware that he is speaking in English rather than Stephen's own language and he is but only paying Stephen minimal attention. Stephen becomes more disillusioned with those around him.
This increasing sense of isolation as Stephen moves towards becoming the artist he realises that he wants to be is mirrored by the way that the novel ends with Stephen's voice alone with no other interruptions. The final section of the novel represents Stephen addressing himself in a journal form without any narrative intrusion. Stephen therefore in the course of this chapter moves ever closer towards the isolation that he feels is vital to be an artist and to create.
