The idealized model of the public sphere based on liberal, Enlightenment political theory is best described by Jürgen Habermas. But its assumptions and problems are deeply embed-ded in our traditions of a liberal, humanistic education (Atwill; Roberts-Miller). Called the “bourgeois public sphere” because of its roots in the rise of the middle class and capitalism, this ideal asserts the need to bracket or ignore social difference, to exclude the personal and private in a focus on common concerns, and to arrive at consensus though critical-rational argument.
This is saying that individuals should take their lives experiences and put them to the side and be objective and rational. I don't think this would be effective at all because nobody is going to be able to give a good argument for something they need if they are unable to introduce their personal experiences and why they need it. People need community literacy and to use it in their debates.
