Criticism or Positivism?

El Lissitzky's "Lenin Tribune" (1925)

A fairly interesting discussion is going on over here regarding the imperative for the Left to either critique (negate) ideologies or produce (posit) its own ideology.  Predictably, I maintain that the outline of a different future is best conceived as the negative image of the present.  Hegelian sublation was never a “synthesis” but rather the antithesis of the antithesis, the negation of the negation, expropriating the expropriators (Marx).
