Unknown Unknowns.  Ami Clarke.  (text work, 2009).

Quote by Donald Rumsfeld, the former US Secretary of Defence during a news briefing in the lead up to the Iraq war, in 2002 that betrays itself, in its seemingly absurd investigation into what might be regarded as the truth. As a statement essentially designed to put the general public and media off the scent, it displayed a remarkable lack of self-awareness, as it alludes to the actual activity of covering up the truth, and mention of the ideological 'unknown knowns' that structure society itself. (With a nod to the structure of the Ettore Sottsass room divider, Memphis group, early 1980's).
