Attempt at Habermas

I am not totally sure what Habermas is really saying that relates to rhetoric but heres a shot at it. Habermas is separating the public and private spheres. These are spheres that were recognized as important parts of life, but have sort of slipped by the wayside. He says that to be a sphere of influence, the people involved must share common believes and ideas. In the public sphere, you would only discuss and suggest things that fit into the common beliefs that you share. For example, in America we all share the belief of freedom so things that allow freedom can commonly be discussed; whereas, we do not all share a common belief in religion and so religion is something that is kept for a smaller, more private sphere.
Habermas also says that there are three things that define the public sphere: work, interaction, and power. He says that these things carry between the public and private spheres. Habermas also introduces the idea of the “lifeworld” which he defines as “the immediate miliu of the individual social actor” (242). He says that the lifeworld is the life in the public sphere and the social world.
I am not totally sure on what exactly he is saying about rhetoric but perhaps it has something to do with the different types of rhetoric that can be used in each sphere.
