For this notion defines the present in which he himself is writing history. The historical materialist leaves it to others to be drained by the whore called 'Once upon a time' in historicism's bordello. He remains in control of his powers, man enough to blast open the continuum of history. XVII Historicism rightly culminates in universal history. Materialistic historiography differs from it as to method more clearly than from any other kind.
Universal history has no theoretical armature.
Materialistic historiography, on the other hand, is based on a constructive principle. Thinking involves not only the flow of thoughts, but their arrest as well. Where thinking suddenly stops in a configuration pregnant with tensions, it gives that configuration a shock, by which it cristallizes into a monad. A historical materialist approaches a historical subject only where he encounters it as a monad. In this structure he recognizes the sign of a Messianic cessation of happening, or, put differently, a revolutionary chance in the fight for the oppressed past.
