Professor Chan: The literature department' s undergraduate courses should cover only true literary works, and not such frivolous material as advertisements  Professor Wigmore: Advertisements might or might not be true literary works but they do have a powerfully detrimental effect on society -- largely because people cannot discern their real messages  The literature department' s courses give students the critical skills to analyze and understand texts
Ttherefore, it is the literature department' s responsibility to include the study of advertisements in its undergraduate courses
Advertisements ought to be framed in such a way that their real messages are immediately clear.
