Margret Thatcher, October 31, 1987 • Sie ist eine Differenz. Sie ist nicht nur ein Objekt mit bestimmten Qualitäten. Sie ist eine Differenz, die sie selber erzeugt, wobei auf der einen Seite die innere Seite dieser Differenz, das heißt, das was die Gesellschaft tut, wie sie operiert, wie sie beobachtet, wie sie kommuniziert zu sehen ist, aber auf der andere Seite auch noch etwas.
