Marx analyses capitalist production as if it were a natural phenomenon, whose behaviour is lawlike. But he prefaces the whole discussion with the assertion that society is not static, but changing, and the laws he elucidates are specific to given circumstances. They appear to be law-like, operating beyond our control, but the very process of identifying these alienated social forms is the first step on the way to overthrowing them. Over and again he reminds us that the apparently independent power that capital exercises over us is nothing more than the alienated form of human activity, reappearing to us as a hostile force. As Korsch says, the point of the socialist movement is to substitute the free agency of the working class for the blind operation of the market.
