Surplus value vs Surplus enjoyment

Herein lies the difference from Marxism: in the predominant Marxist perspective the ideological gaze is a partial gaze overlooking the totality of social relations, whereas in the Lacanian perspective ideology rather designates a totality set on effacing the traces of its own impossibility. This difference corresponds to the one which distinguishes the Freudian from the Marxian notion of fetishism: in Marxism a fetish conceals the positive network of social relations, whereas in Freud a fetish conceals the lack ("castration") around which the symbolic network is articulated.
