Every branch of knowledge has a central concept that expresses the fundamental feature or function of the sector of reality it investigate and deals with. The pivotal category of political science is the state.
The state did not always exist. Certain sociologists and other representatives of academic political science are in error when they speak of the state in primitive societies. What they are really doing is identifying the state with the community. In so doing, they strip the state of its special characteristic.
Through the struggle waged by the labour movement certain institutions of the bourgeois state become both more subtle and more complex.
When we say that the state remains in existence up to and including the transitional society between capitalism and socialism, the question arises whether the working class still needs a state when it takes power.
