ESPN12, Marx and Althusser

In Marx’s writings one can see the ideas of classes and that the class with the most material force is equal to the class that is the intellectual force. Further more from Marx, I found his idea of the classes as two separate parts and as a whole. It seems that another thing and groups of people can be parts and whole. As a Steeler fan we are part of the Pittsburgh sports culture. However, on a greater note, they are a part of the NFL and the Steelers, like other teams are a part of something greater.
Just has there are parts within Marx, there are two parts with Althusser, He explains the RSA and ISA. These are terms I never quite grasped in 100 however I now believe I further understand and they seem to be a simple concept. RSA leaves room for people to question the ideologies while the ISA leaves no room for such things. ISA can be such things as church or a political system which gives you a guide line for life. I question is this almost the same thing as with Lyotard and the previously discussed idea of a mena-narratives? The authors both speak of ideologies as well. We use ideologies to explain things that happen, they seem to be greater ideas then the ones we have control of on a personal level. Ideologies are a greater idea for instance they might be on a political level. Though, I understand ideology, if you will, has a hegemonic idea, which as we saw from Marx seems to be the group with the most materials. The group that is in power, “the upper class”, is the ones that enforces ideologies on others. People then accept that and rarely question even though the dominant class may not always be right. It is as if the ideology’s control people; I understand an ideology to be one grand idea with two separate kinds, an RSA and ISA. Furthermore, there is a regular idea and an ideology.
