Contradictions in the material world had to be met head-on, lived through, and finally transcended by leave of practical activity. Thus if one says that the class struggle ought not to exist, one is still a long way from ending it. For the class struggle exists as long as production and exchange are mediated through the bourgeois form of private ownership. Said laws of motion are the means by which practical activity remains bound to certain conditions of possibility. In terms of the class struggle under capitalism, the revolutionary moment comes about when the conflict between social production and private ownership can no longer be satisfactorily resolved in the eyes of the proletariat.
Immanent critique emphasizes that the transcendence of historical necessity is a vexed process.
Thus an immanent critique must address itself to the tension between tendencies and laws, which itelf is productive of historical movement. The tendency is usually of one mode of production, the law of another. Which is to say, a historical tendency is a historical law whose day has not yet arrived. In the antebellum south, some slaves were permitted to hire themselves out and earn their own money. This might be seen as a historical tendency in the sense that wage labor was the more typical form of exploitation in post-Jacksonian America.
