That's the sad reality.
I'm studing sociology since 2007 and no one can convince me. Who are Marx, Weber and Durkheim?, Who are Parsons, Luhmann, Giddens, Habermas and Bourdieu? Who are member of the Frankfurt School?...All of them have reason, and that's the big problem.
If u are learning about systems theory, Parsons, Luhmann, Arnold & Rodriguez will be correct in their analysis, but if you are studing about marxist theory, all the different authors of that theory, will be your favorite. Has been common for me, be in the science's kiosk with my friends talking about this. One day I'm the biggest fan of Althusser, but the next day, I will "give a child" to Bourdieu.
And I think that's normal, because we are learning about it...we are just students.The reason about that, I think, is that I'm idealist (only in sociology). I'm expecting about "THE THEORY", one specific and perfect viewpoint. Other reason could be, the clear political position that I have about the role of the discipline in the society. If the sociology don't theming the social inequialities...NEXT!
I'm expecting to find my favorite theory or author, but actually, I'm just a geek.
