What history grasps in an event is the way it’s actualized in particular circumstances; the event’s becoming is beyond the scope of history. History isn’t experimental, it’s just the set of more or less negative preconditions that make it possible to experiment with something beyond history. Without history the experimentation would remain indeterminate, lacking any initial conditions, but experimentation isn’t historical … history amounts only the set of preconditions, however recent, that one leaves behind in order to “become,” that is, to create something new.
