In Marx's words, ideology is as "the ruling ideas of the ruling class." Those with wealth control the means of making wealth. Thus in Jane Austen's novel, Pride and Prejudice, Mr. Darcy owns Pamberly House and its estate. People who live in Pamberly work for him. Their productions belongs to Mr. Darcy and they receive wages and annual income distributed from him. Those workers in Pamberly do not complain because they do not know how and why. More, it is Mr. Darcy and Lady Catherine who think the Bennets' social status do not suitable for the life of aristocracy. And again we find that none character, except Elizabeth, denies it.
Moreover, Louis Althusser and nowadays' convince reckons the term ideology as "processes of cultural signification and personal formation that cannot be summed up merely as ruling class. It also consists of training in certain practices of self-discipline or certain modes of self-identification" (Rivkin and Ryan, 237). Therefore, also in Pride and Prejudice, we can tell that Darcy's workers and housekeepers see Mr. Darcy's nobility as granted because they are taught to believe so. And so does Mr. Darcy himself. Elizabeth rebukes Lady Catherine's warning and decides to marry Mr. Darcy is out of contemporary ideology. At her time, the aristocratic speaks louder not only because his or her high social position but also because the whole society has the same common view.
