The purpose of the second letter serves as a reminder that she never wanted to hurt him. With reminding him of what she did, she does not care of how he sees her since he has left her during these dark times questioning his cruel actions. In both letters that Tess writes, the circumstances she is put into effect the purpose of writing to Angel.
In the first letter, Tess expresses her tone of sorrow by all three rhetorical appeals and as her tone changes to anger she expresses it only in paphos. Tess begins her first letter with pathos calling herself "an unworthy wife"" (353) "exposed to temptation " (353), but is still "[clung] to [Angel] in a way [he] cannot think"" (353). Her tone begins in remorse because of how she made Angel feel and writes in her regret. However, she writes to reach sympathy and pity from Angel of the state she is in at the moment without his presence. Tess then moves on to using logos, taking hold of Angel's logical mind and clarifying her understanding that "it was necessary [for Angel to] find a farm "(353). She continues in her tone of understanding and accepting that she is the person who did wrong and excusing Angel for leaving her. It has become has become logical to her that Angel had to leave for finding a farm, displayed as a necessary, since Tess now believes it was his husband duty to do so. Tess also uses ethos in her first letter to convince Angel to return since her beauty "may be at least one thing about [her] worth [his] having"" (354). She believes in her morals of marriage that all she has to offer is for her husband, even if he dislikes her, her appearance is all she has for him. Her tone makes her appear humble and exhibit that she wants to re-establish the love between them and wants him home. Regardless, in the second letter, Tess uses only pathos calling Angel "cruel indeed"" (374), since he "treated [her] so monstrously"" (374). She no longer is convincing Angel to come back and her tone changes to anger.
