Vaclav Havel:

Obviously the greengrocer is indifferent to the semantic content of the slogan on exhibit; he does not put the slogan in his window from any personal desire to acquaint the public with the ideal it expresses. This, of course, does not mean that his action has no motive or significance at all, or that the slogan communicates nothing to anyone. The slogan is really a sign, and as such it contains a subliminal but very definite message. Verbally, it might be expressed this way: "I, the greengrocer XY, live here and I know what I must do. I behave in the manner expected of me. I can be depended upon and am beyond reproach. I am obedient and therefore I have the right to be left in peace." This message, of course, has an addressee: it is directed above, to the greengrocer's superior, and at the same time it is a shield that protects the greengrocer from potential informers. The slogan's real meaning, therefore, is rooted firmly in the greengrocer's existence. It reflects his vital interests. But what are those vital interests?

Let us take note: if the greengrocer had been instructed to display the slogan "I am afraid and therefore unquestioningly obedient;' he would not be nearly as indifferent to its semantics, even though the statement would reflect the truth. The greengrocer would be embarrassed and ashamed to put such an unequivocal statement of his own degradation in the shop window, and quite naturally so, for he is a human being and thus has a sense of his own dignity. To overcome this complication, his expression of loyalty must take the form of a sign which, at least on its textual surface, indicates a level of disinterested conviction. It must allow the greengrocer to say, "What's wrong with the workers of the world uniting?" Thus the sign helps the greengrocer to conceal from himself the low foundations of his obedience, at the same time concealing the low foundations of power. It hides them behind the facade of something high. And that something is ideology.
