Answer:
The author's argument in the passage is that the emotion that the man is feeling (presumably Hamlet) is complex and difficult to understand, and cannot be adequately expressed or objectified. This emotion, which is in excess of the facts as they appear, is caused by the man's disgust with his mother, but his mother is not an adequate equivalent for this disgust. As a result, the emotion remains unexpressed and poisons the man's life and obstructs his actions. The author suggests that no action can satisfy this emotion, and that Shakespeare was unable to effectively express it through the plot of the play. The author also notes that presenting characters in action, such as the sleepwalking scene in "Macbeth," can be an effective way to evoke emotion in the audience.
