The Contemporary Reception of the Class Struggle – to What Extension the Marxism Impacted on XXth-century’s Conceptions and is it Valid until Today?

The aim of this paper is to compare the Karl Marx’s theory of classes fighting to influenced by it a neo-marxist conception of Ralf Dahrendorf concerning conflicts and arguing with a theory of social system elaborated by Talcott Parsons. Such an arrangement mostly enables answering the question in what extension the conceptions of a XIXth – century philosopher and an economist remain up-to date in the following century. In the second part of deductions the evolution of that term will be presented in a form of showing as examples the followers of the mentioned thinkers, because contemporarily the term of classes fighting is used not only by Marxists, but also by the members of feministic movements such as Pierre Bourdieu and representatives of organizations which fight for a protection of the environment, among others Murray Bookchin. Such different points of view will be shown and compared in this paper, which will lead to answering the question in what extension the thoughts of Karl Marx influence XXth-century philosophy and if they are still up-to-date.
