You know it is not sound, and that you would never act this way yourself." Because of the point of view of the text, the reader is encouraged to agree with Elizabeth's view. This shows that Austen also feels alike to Elizabeth, and thusly she fulfills her aim of criticizing the marriage procedure of the time.
This criticism is carried throughout the novel and next appears in force after Mr. Collins proposes marriage to Elizabeth. Not two days after this proposal does Mr. Collins make a similar proposal to Charlotte Lucas. During Collins" proposal to Elizabeth we see her attitude towards him, she believes him to be ridiculous and obsequious. This encourages the reader to view him as a totally unsuitable marriage partner for anybody, despite his monetary attractions. So when Charlotte accepts his proposal the reader has been positioned to immediately disapprove of the union. When Elizabeth asks Charlotte why she is going to marry this "disagreeable" man, charlotte replies; "I am not romantic I ask only a comfortable home, and considering Mr. Collins's character, connections, and situation in life, I am convinced that my chance of happiness is fair." With the reader already positioned to view this marriage negatively, the reader is now positioned to view her reasoning negatively. And so Austen has been able to input her criticism of Napoleonic marriage reasoning yet again, this strengthens the negative connotations already put upon marrying for monetary or social advantage. .
Whilst Austen is discrediting the above marriage reasoning she is also putting forward her values on the subject through Elizabeth. Elizabeth's view is that of marriage for love & reason, this is positioned positively for the reader by the fact that this view goes against marrying the obsequious Mr. Collins who is the most "disagreeable" man presented in the entire novel. Elizabeth is also presented with another proposal for marriage later in text.
