Persuasion was entitled Jane Austen died, by her brother. Austen herself seems to have referred to the work as The Elliots. While dealing with the traditional Austenian themes of class and society, persuasion itself is an important theme throughout the book. Anne allows herself to be persuaded by her family to give up on Frederick (whom she is still in love with). This speaks to the norms and mores of the day where women were eminently pressured – by their family as well as society at large – to act a certain way. To persuade or be persuaded, rightly or wrongly, is an important part of society; and whose persuasion one falls under can have a significant impact on their life (as well as the life of another, as is the case in Persuasion).
Like all of Jane Austens works, Persuasion has been adapted to multiple mediums of media. If you want to do a deep dive into the text the Norton Critical Edition is ideal. If you’d like a full set of Austens works, this is an affordable option.
