Professor Dedalus

This section starts out in Stephen's classroom mid class. What struck me most about this portion of the section was how poor of a professor he seemed to be. His students didn't seem to know much, he got lost in thought and changed subjects without completing them. What about the history? one of his students asks, Oh we can get to that later. Then when Sargent comes in with his math work, though he helps him, Stephen also seems to quietly loathe him. The connections between his own awkward childhood and experiences at school, illustrated in Portrait, seem pretty clearly drawn and therefore point to self loathing, but his incompetence as a teacher is curious to me. Maybe the fact that he is working a job that is not artistically fulfilling and is a waste of his intellect causes him to not care enough to put effort into the job? I'm not sure. What do you all think?
