In particular, we may distinguish and place against one another: a zone of singularities wherein the demonstrated adheres to the demonstration to the point of being indistinguishable from it, characterising a unique moment of science; and on the other hand the set of concatenations proper, which, although they are binding only in so far as they actually demonstrate something and thus cannot be redeployed in their entirety elsewhere, nonetheless display commonalities of type from group to group—they bear the mark of the unity of all such movements, [a unity] that can be manifested in the abstract.…
