Analysis: Emotion and Jon

The extract under analysis is taken from the great work “The Forsyte Saga”. The events in the extract are presented in chronological order. The form of representation is narration broken by dialogues, descriptive narration and half-reported speech. It’s a 3rd person singular.

Fleur is young, may be slightly vulgar lady. “Fleur was smiling, a little defiantly…”. Jon’s mother (Irene) appears in us as a calm and wise woman. “…his mother’s startled face was changing quickly to the impersonal and gracious”, “his mother said quietly…”. And only description of Jon’s father can be direct. “…in the eyes of that tranquil figure, with his knees crossed, thin, old, and elegant…” Judging by that as Jon is afraid of the reaction of his father we can tell that his father is the strict man.

Here high emotional rise is felt. Especially it’s concerned of Jon. “There are various kinds of shocks: to the vertebrae; to the nerves; to moral sensibility; and, more potent and permanent, to personal dignity.” The emotions of Fleur and Irene are calmer.
